Through such setting, the material subassembly 500 is carried to the cooperation outside, and this anchor clamps subassembly can realize the automatic centre gripping to section bar 400 for section bar 400's promotion and fixed need not manual operation, and is easy and simple to handle, and can reduce section bar 400 wearing and tearing in the course of working, is favorable to improving the processing yield.

Referring to fig. 1 to 3, in some embodiments of the present application, a plurality of slot positions 120 are provided at one side of a base 100, the slot positions 120 are provided in one-to-one correspondence to troughs 110, and bottoms of the slot positions 120 communicate with the troughs 110; the body 210 is rotatably disposed in the slot.

It can be understood that the slot 120 may be opened at one side of the base 100, or may communicate with two adjacent sides of the base 100, only that the body 210 can rotate in the slot 120. When the slots 120 communicate with two adjacent sides of the base 100, the body 210 can be more easily installed and the rotational angle of the clamping mechanism 200 can be increased.

Referring to fig. 1 to 3, in some embodiments of the present application, the driving member 300 includes a rod 310 and a driving mechanism 320, the rod 310 is disposed parallel to the rotation axis of the body 210, and the driving mechanism 320 is configured to drive the rod 310 to abut against the body 210 and drive the body 210 to rotate to the clamping position.

It can be understood that the rod 310 of the driving member 300 is arranged parallel to the rotation axis of the clamping mechanism 200, when the rod 310 is driven by the driving mechanism 320 to move in the direction parallel to the trough 110, the rod 310 abuts against the protrusion 211 on the body 210, so that the body 210 is driven by the rod 310 to rotate along the rotation axis, the end of the body 210 near the top side is close to the trough 110 and clamps the profile 400 in the trough, and after the profile 400 is clamped in the trough 110, the driving mechanism 320 keeps the rod 310 unchanged, so that the profile 400 is stably fixed in the trough 110, and thus the machine tool main cutter can perform the cutting and milling process on the profile 400. Through such setting, driving member 300's occupation space is less, and drive power is big, drive stability is high and low cost.

Referring to fig. 1 and 2, in some embodiments of the present application, the driving mechanism 320 is fixedly disposed on the base 100, the driving mechanism 320 includes two air cylinders, two air cylinders are disposed at two ends of the base 100, and two ends of the rod 310 are connected to driving ends of the two air cylinders.

It can be understood that through holes are opened at two sides of the base 100, two cylinders are provided and are respectively fixedly disposed at the bottom side of the base 100, and the driving ends penetrate through the through holes, the rod member 310 is connected to the driving ends of the two cylinders, and the two cylinders synchronously operate to drive the rod member 310 to move along a direction parallel to the trough 110 and abut against the protrusion 211 of the body 210.

Meanwhile, it should be noted that the mounting holes are disposed on two sides of the base 100, so that the base 100 can be mounted on the rotating mechanism or other driving mechanism 320, and the base 100 can rotate at multiple angles, thereby implementing processing of different structural angles of the profile 400.

Through such setting, set up actuating mechanism 320 in base 100, actuating mechanism 320 can carry out multi-angle rotating together with base 100 to make section bar 400 all can be lifted and press from both sides tightly in silo 110 under any angle, make things convenient for the processing of section bar 400.

It can be understood that the protrusion 211 is disposed on a side of the body 210 away from the trough 110, and a side of the protrusion 211 on the body 210 protrudes out of the trough 120, so that the lever 310 does not need to have a convex structure to extend into the trough 120 to abut against the protrusion 211 on the body 210, and therefore, the lever 310 can be configured as a straight rod. With this arrangement, the rod member 310 can be manufactured at low cost.

Meanwhile, the abutting position of the protrusion 211 of the body 210 and the rod 310 is an inclined plane or an arc surface. By such arrangement, when the rod 310 abuts against the protrusion 211 and drives the body 210 to rotate in the groove 120, the rotation of the body 210 is smoother, so that the acting force on the profile 400 at the moment when the clamping mechanism 200 abuts against the profile 400 is reduced, the profile 400 is prevented from being bent and deformed due to sudden stress, and the surface of the profile 400 can be kept smooth and free from indentation.

Referring to fig. 4, in some embodiments of the present application, a side of the body 210 facing the trough 110 is provided with a first clamping portion 220, and the first clamping portion 220 protrudes from the surface of the body 210; when the body 210 is in the clamped position, the first clamping portion 220 is adjacent the trough 110.

It is understood that the first clamping portion 220 is disposed at a position where the clamping mechanism 200 is close to one side of the trough 110 and close to the top side of the clamping mechanism 200, and the width of the first clamping portion 220 is smaller than the width of the trough 110; meanwhile, it should be understood that the first clamping portion 220 is made of plastic material. So set up for section bar 400 can obtain better fixed centre gripping in silo 110.

Referring to fig. 5 and 6, in some embodiments of the present application, the first clamping portion 220 is embedded in the body 210, and a first elastic member 230 is disposed between a side of the first clamping portion 220 away from the trough 110 and the body 210.

It is understood that the first clamping portion 220 is embedded in the body 210. Specifically, an installation position is formed in the body 210, the installation position communicates with the top surface of the body 210 and a side surface of the material groove 110, and meanwhile, the clamping mechanism 200 further includes an upper cover plate, the upper cover plate is used for covering the installation position, and when the first clamping portion 220 is installed in the installation position, the upper cover plate is connected with the body 210 through a bolt, so that the installation of the first clamping portion 220 can be completed. So set up, first clamping part 220 easy dismounting.

In order to alleviate the force applied to the profile 400 at the moment when the clamping mechanism 200 abuts against the profile 400 and to allow the clamping mechanism 200 to continuously and stably fix the profile 400 to the trough 110, the first elastic member 230 is provided between the main body 210 and one side surface of the first clamping portion 220 away from the trough 110, and the first elastic member 230 may be a rectangular spring.

Meanwhile, in order to prevent the rectangular spring from ejecting the first clamping portion 220, which affects the rotation of the body 210 in the slot 120, a limit structure is provided on the first clamping portion 220. Specifically, limit structure is for setting up the bulge in first clamping part 220 both sides, and under the elastic force effect of rectangle spring, the bulge and the inside wall butt of installation position to the distance that stretches out of restriction first clamping part 220.

Referring to fig. 3 and 7, in some embodiments of the present application, a second elastic member 130 is fixedly disposed at the bottom of the trough 120 on both sides of the trough 110, and the second elastic member 130 is used to keep the body 210 in the release position.

It can be understood that, when the profile 400 needs to be lifted to a certain height, the driving mechanism 320 drives the rod 310 to return to the original position, at this time, the rod 310 is separated from the abutting state with the clamping mechanism 200, in order to make the first clamping portion 220 completely separated from the abutting state with the profile 400 when the profile 400 is lifted, so as to reduce the resistance when the profile 400 is lifted, specifically, the second elastic members 130 are fixedly disposed at the bottom of the slot 120 and at the two sides of the trough 110, the second elastic members 130 may be springs, meanwhile, the acupuncture points 240 are correspondingly disposed at one side of the body 210 opposite to the bottom of the slot 120, the acupuncture points 240 are disposed at the top side close to the body 210, and one end of the second elastic member 130 facing the body 210 is inserted into the acupuncture points 240. When the rod 310 is out of abutment with the protrusion 211 on the body 210, the second elastic member 130 pushes the body 210 to rotate along the rotation axis, so that the first clamping portion 220 on the clamping mechanism 200 is completely out of abutment with the profile 400, thereby reducing the moving resistance of the profile 400 during lifting.

Referring to fig. 4 and 6, in some embodiments of the present application, the clamping mechanism 200 further includes a second clamping portion 250, the second clamping portion 250 is disposed on the same side of the body 210 as the first clamping portion 220, the second clamping portion 250 is inserted into the body 210 and disposed opposite to the trough 110, and a third elastic member 260 is disposed between the second clamping portion 250 and the body 210, and the third elastic member 260 is configured to maintain the second clamping portion 250 in the pop-up state.

It can be understood that when the rod 310 leaves the protrusion 211 on the body 210 and the second elastic member 130 pushes the clamping mechanism 200 to rotate in the slot 120, the profile 400 is lifted by the external lifting assembly 500 to a certain height, however, the lifting assembly 500 is merely inserted into the groove 420 on the profile 400, and the possibility of shaking or external force influence is not eliminated during the lifting process, because there is no contact between the profile 400 and the clamping mechanism 200, if the shaking amplitude is too large, the profile 400 is separated from the lifting assembly 500, the profile 400 directly slides in the slot 110, and a serious person may cause the profile 400 to deform or even to be discarded.

To avoid this, a second clamping portion 250 is provided on the clamping mechanism 200. Specifically, the second clamping portion 250 is disposed on the same side of the body 210 as the first clamping portion 220, the second clamping portion 250 is inserted into the body 210 and disposed opposite to the trough 110, and a third elastic member 260 is disposed between the second clamping portion 250 and the body 210, the third elastic member 260 may be a rectangular spring, and the third elastic member 260 is used for keeping the second clamping portion 250 in an ejecting state all the time, so that the second clamping portion 250 always abuts against the profile 400 in the trough 110 and applies a certain pressing force to the profile 400. It should be noted that the elastic force of the third elastic member 260 is smaller than that of the first elastic member 230, and when the body 210 is in the release position and the lifting assembly 500 is lifting the profile 400, the second clamping portion 250 does not obstruct the lifting of the profile 400.

When the rod 310 abuts against the protrusion 211 on the body 210, the first clamping portion 220 abuts against the profile 400, and at this time, the second clamping portion 250 also abuts against the profile 400 under the elastic force of the third elastic member 260; when the rod 310 is driven by the driving mechanism 320 to leave the protrusion 211 on the body 210, the second elastic member 130 pushes the body 210 to rotate in the groove 120, and during the rotation, the second clamping portion 250 is always abutted against the profile 400 under the elastic force of the third elastic member 260 to prevent the profile 400 from sliding down in the groove 110; when the body 210 is in the release position, the second clamping portion 250 abuts against the profile 400 under the elastic force of the third elastic member 260. Through so setting up, be favorable to improving the stability of section bar 400 in silo 110 when promoted, prevent that section bar 400 from receiving to rock and landing in silo 110, be favorable to improving the processing yield.

Referring to fig. 3 and 7, in some embodiments of the present application, an air passage is provided in the base 100 and an air outlet 140 is provided at the opening of the trough 110 on the top side of the base 100.

In the machining process, when one end of the profile 400 is cut and milled to form a product piece 410, the clamp assembly is driven by the driving mechanism 320 and inserts the end, on which the product piece 410 is formed, of the profile 400 into a die position of another clamp mechanism, and then a main cutter of a machine tool cuts along the groove 420 on the profile 400 to separate the product piece 410 from the unprocessed profile 400. Because the cutting and milling process can generate a large amount of scraps, the generated scraps can be left on the processing station, and if the scraps are not cleaned completely, the scraps can scratch the surface of the product piece 410, so that the surface smoothness of the product piece 410 is not satisfactory. For this reason, through setting up the air flue in base 100, and set up venthole 140 in the silo 110 of base 100 topside near the mouth, when the anchor clamps subassembly bears the motion of section bar 400 and inserts the one end that is formed with product piece 410 on section bar 400 and establishes in the mould position of other fixture mechanism, venthole 140 of base 100 topside begins to blow, clears away the sweeps that leave over in the fixture mechanism mould position after the last round of cutting, and makes the fixture mechanism mould position keep clean to avoid product piece 410 fish tail damage in the mould position, influence the product yield.

The embodiments of the present application have been described in detail with reference to the drawings, but the present application is not limited to the embodiments, and various changes can be made without departing from the spirit of the present application within the knowledge of those skilled in the art.
