Example 1

As shown in fig. 1 to 4, and in particular in fig. 1 and 2, the present invention relates to an assembly 100 comprising: a motor 110; a motor telescopic rod 111 fixedly connected with the motor 110 and driven by the motor 110; a guide rod 120; a lifting platform 130 fixedly connected with the motor telescopic rod 111 and the guide rod 120; and a jig 1.

Specifically, the motor 110 is used for driving the motor telescopic rod 111 to move up and down, the clamp 1 is used for limiting the motor 110 and the guide rod 120 so as to prevent the motor 110 from displacing or shaking in the driving process, the lifting platform 130 is installed at one end of the motor telescopic rod 111 and one end of the guide rod 120, and the lifting platform 130 can move up and down along the guide rod 120 through the up-and-down movement of the motor telescopic rod 111, so that a user can implement operation at the lifting platform 130.

As shown in fig. 1-4, and with particular reference to fig. 2, the assembly 100 of the present invention further includes a positioning support bar 140.

Specifically, the positioning support rods 140 are disposed at the left and right sides of the freezing point osmometer to further prevent the body from shaking.

As shown in fig. 1 to 4, and in particular in fig. 3 and 4, the clamp 1 of the assembly 100 according to the invention comprises: a first arm 10; a second arm 20; a first through hole 30 for fixing the guide bar; and a second through hole 40 for fixing the motor; wherein, one end of the first arm 10 close to the first through hole 30 and one end of the second arm 20 close to the first through hole 30 are of a seamless integral structure; wherein the first through hole 30 and the second through hole 40 are limited by the first arm 10 and the second arm 20.

Specifically, as shown in fig. 3, the heights of the first and second arms 10 and 20 near the first through hole 30 are higher than the heights of the first and second arms 10 and 20 near the second through hole 40, and preferably, the heights of the first and second arms 10 and 20 near the first through hole 30 are twice as high as the heights of the first and second arms 10 and 20 near the second through hole 40. A motor (not shown) is fixed to the second through hole 40, and a guide rod (not shown) is driven by the motor to move up and down along the first through hole 30.

As shown in fig. 3 to 4, an end of the first arm 10 close to the second through hole 40 is provided with a first extension 11 extending outward, an end of the second arm 20 close to the second through hole 40 is provided with a second extension 21 extending outward corresponding to the first extension 121, and a gap 50 is provided between the first extension 121 and the second extension 122.

Specifically, the gap 50 is preferably 1mm, and the gap 50 provides a favorable elastic space for the process of fixing the motor (not shown in the figure), so that when the second through hole 40 is not completely matched with the shape of the motor, the motor can be effectively prevented from being damaged due to the extrusion of the second through hole 40 to the motor.

As shown in fig. 3 to 4, an end of the first arm 10 close to the first through hole 30 and an end of the second arm 20 close to the first through hole 30 are provided with a third extension 123 extending outward in a direction opposite to the extending direction of the first extension 121 and the second extension 122.

As shown in fig. 3 to 4, and particularly referring to fig. 4, the first extension 121 and the second extension 122 are provided with at least one mounting hole 61 in a direction perpendicular to the axial direction of the first through hole 30 and the second through hole 40.

As shown in fig. 3 to 4, and particularly referring to fig. 4, the third extension 123 is provided with a mounting hole 62 in a direction perpendicular to the axial direction of the first through hole 30 and the second through hole 40.

Specifically, the mounting holes 61 and 62 are used to fix the jig 1, on which the motor and the guide bar are mounted, to a mechanical assembly, such as a mechanical device having a transmission structure. In use, the user first fixes the guide bar and the motor by being sleeved with the first through hole 30 and the second through hole 40 in the clamp 1, and then the user can fix the clamp 1 with the motor and the guide bar mounted to the mechanical assembly by fixing screws or pins into the mounting holes 61 and the mounting holes 61, respectively. During the use process, a user can optionally select and use one or more of the mounting holes 61 and the mounting holes 61 according to the actual output power of the motor, the vibration frequency and amplitude of the guide rod during the up-and-down movement process, whether the guide rod is stopped or stopped due to excessive friction force during the up-and-down movement process, and the like.

According to a preferred embodiment of the present invention, the diameter of the first through-hole 30 is 11mm, and the diameter of the second through-hole is 30 mm.

According to a preferred embodiment of the invention, the diameter of the mounting hole is 5 mm.

Specifically, the diameter dimensions of the mounting holes 61 and 62 may be selected from: 1mm, 2mm, 3mm, 4mm and 5 mm. Preferably, the diameter size of the mounting holes 61 and 62 is 5 mm.

According to a preferred embodiment of the present invention, the ends of the first and second arms 10 and 20 adjacent to the first through hole 30 have a radius of curvature corresponding to the first through hole 30, and the ends of the first and second arms 10 and 20 adjacent to the second through hole 40 have a radius of curvature corresponding to the second through hole 40.

The clamp 1 can be machined and also can be printed in a 3D mode, and different materials can be selected according to the actual needs of users. The processing is convenient, and the cost is lower. The clamp 1 related by the invention replaces a motor fixing frame in the original mechanical structure, has a simple structure, and can be conveniently moved or placed by a user according to actual needs.
