The working principle of the invention is as follows: when a user needs to use the invention to clamp a right shell of a differential gear machine from another clamping jaw to turn over, the invention is pushed to another clamping jaw through the air cylinder, in the process that the embedded disc 5 contacts the right shell of the differential gear machine and the right shell of the differential gear machine is embedded into the right shell, the rod part 3 is pressed to the floating seat 7 until the lower rod surface 31 is abutted to the floating groove 8, a certain floating space is required to be reserved between the side wall of the floating groove 8 and the side wall of the rod part 3, meanwhile, the floating spring 13 is compressed, the upper groove 9 and the lower groove 10 are gradually closed, the rod body caliber of the control rod 12 is smaller than the groove top caliber of the control groove 11, and at the moment, the circular truncated cone end of the control rod 12 is separated from the upper half part of the control groove 11 which is relatively embedded, enters the floating space of the lower half part of the control groove 11 and can move in all directions; if the positioning is not accurate and the adjustment is needed, the rod part 3 can be correspondingly displaced, so that the embedded disc 5 is driven to be displaced to a proper position to be embedded with the right shell of the differential mechanism;

after the right shell of the differential gear machine is embedded, the air cylinder resets, the floating spring 13 pushes the rod part 3 away through elastic force when no external force is applied to the compression, the upper groove 9 and the lower groove 10 are separated, the control rod 12 fixed in the upper groove 9 is pulled up, the truncated cone end of the control rod 12 is embedded into the control groove 11 again and can not move any more, and the rod part 3 can also be reset to the original position at the moment

When a user uses the invention to carry out the embedding of the embedded disc 5, if the positioning is inaccurate, the rod part 3 can deviate to a certain extent, the embedded disc 5 is embedded to the right shell of the differential mechanism after the flexible position adjustment, compared with the traditional clamping jaw with a rigid structure, the invention does not bear the bending stress generated on the rod part 3 by the embedded disc 5 adjustment and the hard embedding to the right shell of the differential mechanism, but achieves the purpose of eliminating the bending stress by the floating space in the control groove 11 and the floating space between the floating groove 8 and the rod part 3, if the positioning error of the individual differential mechanism is larger, the user can also carry out the position adjustment of the rod part 3 after the manual compression, thereby ensuring that the service life of the invention is longer.

The matching of the limit plate 14, the limit ring 16 and the limit rod 17 can further fix the embedded disc 5 to prevent the embedded disc from slipping when being embedded with the right shell of the differential mechanism; on the other hand, in order to deal with the situation that the lengths of the right shells of the differential mechanism are different when the right shells of the differential mechanism are machined, the whole embedded disc 5 is in a lifting state through the matching of the sliding groove 25, the clamping plate 201 and the sliding plate 202 and the matching of the limiting hole 23, the limiting nut 24 and the threads of the side arm at one end of the limiting rod 17, but a user needs to pull the embedded disc 5, the limiting nut 24 is loosened, the inserting rod is pulled out of the proper ruler section from the inserting hole 4, the clamping plate 201 is driven to be pulled up along with the sliding of the sliding plate 202, and after the position is proper, the limiting nut 24 is screwed again to adapt to the machining of the right shells of the differential mechanism with different lengths.

The compression spring 28 can prevent the user from exerting excessive force when pressing the embedded disc 5 downwards, so that the inserted link is prevented from impacting the bottom of the inserting hole 4 to cause damage to components due to over-violent force, and the effect of buffering the impact force under the inserted link is achieved.

The design of the horizontal positioning grooves 26 and the vertical positioning grooves 27 of the clamping plate 201 can help the clamping plate 201 to be clamped better in edge contact with the fixing plate 18 when the fixing plate 18 is clamped, and the clamping stability is improved.

When the lower rod surface 31 is abutted to the floating groove 8, the hemispherical limit groove 32 of the lower rod surface 31 is pressed above the limit ball 30, so that the rod part 3 turns more roundly, the floating angle of the rod part 3 is limited to a certain extent, the impact of the floating angle on the groove wall of the floating groove 8 is avoided, and the service life of the invention is further prolonged.

The specific embodiments are only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications without inventive contribution to the present embodiments as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
