One side of each of the protruding sliding structures is in sliding abutment with the inner clamping arm of the clamping jaw part. The driving structure drives the clamping jaw part to move towards the clamping jaw body module. The clamping jaw body module and the protruding sliding structure move towards each other in linkage, and the clamping jaw parts interact to clamp the core wire.

[0009] Preferably, the protruding sliding structure comprises two support protruding plates protruding from one end of the clamping jaw body module and spaced apart by a certain gap, and a pulley arranged between the two support protruding plates and in sliding abutment with the inner clamping arm of the clamping jaw part.

[0027] Please refer to Figure 1 and Figure 2 The high-precision multiplying clamp jaw of the embodiment comprises a fixed support module 1, a clamping drive module 2, a guide rod module 3 and a clamp jaw main body module 4. The clamping drive module 2 and the guide rod module 3 are both arranged on one side of the fixed support module 1, a pair of the clamp jaw main body module 4 used in pairs is arranged on the guide rod module 3, and the clamping drive module 2 clamps the protruding sliding structure b1 of the two clamp jaw main body modules 4 through the clamping opening a1 on it. As the opening of the clamping opening a1 gradually becomes smaller, the protruding sliding structure b1 inserted into the inner clamping arm exerts a force on it, so that the two clamp jaw main body modules 4 move towards each other through the guide rod module 3, and the clamp jaw part b2 clamps the core wire.

[0028] In the preferred embodiment, the clamping drive module 2 comprises a drive structure 21 arranged on the fixed support module 1, and a clamping plate 22 arranged on the drive structure 21 and driven by the drive structure 21 to move back and forth in the direction of the clamping jaw body module 4. Specifically, the clamping plate 22 comprises a fixed plate abutting against the drive structure 21, and a clamping opening a1 formed by hollowing out one end of the fixed plate. The clamping opening a1 is a groove hollowed out from the outside to the inside, which is V-shaped or ladder-shaped. When the drive structure 21 is not working, the opening end of the clamping opening a1 faces the two protruding sliding structures b1, and the driving force of the drive structure 21 drives the two protruding sliding structures b1 to abut and be clamped into the clamping opening a1. Due to the structural design of the clamping opening a1 and the force exerted by the inner clamping arms of the clamping opening a1 on the two protruding sliding structures b1, the clamping jaw body module 4 moves towards the other, and the core wire is clamped by the clamping jaw part b2.

[0029] The guide rod module 3 comprises an upper support plate 31 and a lower support plate 32 fixed to the fixed support module 1 and spaced apart, a guide rod 33 fixed between the upper support plate 31 and the lower support plate 32 and penetrating through the clamping jaw body module 4, and a guide sleeve 34 sleeved between the guide rod 33 and the clamping jaw body module 4, assembling the clamping jaw body module 4 and the guide rod 33 with a 0-gap. The 0-gap assembly further improves the stability of the product design, and cooperates with the structure of the clamping opening a1 to make the product have a high-precision core wire clamping effect.

[0030] Each of the gripper body modules 4 comprises a gripper arm 41 through which the guide rod 33 penetrates, the gripper portion b2 perpendicularly arranged on the other end of the gripper arm 41, and the protruding sliding structure b1 protruding from the other end of the gripper arm 41. Specifically, the gripper portion b2 is shaped with a groove, and the grooves of the two gripper portions b2 are circular, so that the gripper portion b2 better grips the core wire. The elastic member is connected between the two gripper arms 41, and when the two gripper body modules 4 move towards each other, the elastic member is elastically compressed, and when the driving structure 21 drives the clamping plate 22 to reset, the elastic member elastically recovers to drive the two gripper body modules 4 to reset. Specifically, the movement path of the clamping plate 22 and the gripper body module 4 is perpendicular to each other. The protruding sliding structure b1 comprises two support protruding plates b21 protruding from the other end of the gripper arm 41 and spaced apart by a certain gap, and the pulley b22 arranged between the two support protruding plates b21 and slidingly abutting the inner clamping arm of the clamping port a1. The two support protruding plates b21 are shaped on the side of the gripper arm 41 close to the other gripper arm 41, and one side is shaped as an inclined structure. When clamping, the inclined side abuts the inner clamping arm of the clamping port a1, and the inner clamping arm generates pressure on the inclined side, and the two gripper arms 41 move towards each other along the guide rod 33, and the gripper portion b2 arranged at one end of the gripper arm 41.

[0031] As can be seen from the above description, the high-precision multiplying gripper of the present application, through the design of the clamping plate 22 and the protruding sliding structure b1, the driving structure 21 drives the clamping port a1 of the clamping plate 22 to move towards the sliding structure b1, and the structure design of the clamping port a1 exerts force on the two protruding sliding structures b1 to drive the gripper portions b2 to interact and clamp the core wire. The structure design is simple and reasonable, improves the clamping force, and effectively improves the stability and precision of the product after clamping the wire.
