Specifically, one end of the guide mechanism 300 is connected with the driving mechanism 200, and the side of the guide mechanism 300, which is far away from the driving mechanism 200, is provided with the gripper assembly 400; the driving mechanism 200 drives the guide mechanism 300 to press against the gripper assembly 400 to provide driving force for the gripper assembly 400 to grip the workpiece, and the guide mechanism 300 guides the gripper assembly 400 to perform automatic alignment operation according to the shape of the workpiece gripped by the gripper assembly 400.
In the disclosed embodiment of the present invention, the driving mechanism 200 may include a second mounting base 210 and a driving member 220, the second mounting base 210 may be fixed to the base plate 100 by bolts, a side surface of the second mounting base 210 may be fixed to the driving member 220, and a telescopic end of the driving member 220 is connected to the guiding mechanism 300. The driving member 220 may be an air cylinder, an electric cylinder, an oil cylinder, etc., as long as a linear motion power source is provided, and the embodiment of the present invention is not particularly limited thereto.
In the disclosed embodiment of the invention, the guiding mechanism 300 may include a first mounting seat 310, a sliding member 320 and a pressing member 330, the first mounting seat 310 is fixedly connected to the base plate 100, and the first mounting seat 310 is located at the retractable end side of the driving member 220.

Preferably, limit baffles (not shown) may be disposed at both ends of the guide slot 311 to prevent the sliding member 320 from sliding out of the guide slot 311. One end of the sliding member 320 is connected to the retractable end of the driving member 220, and as shown in fig. 4, one end of the sliding member 320, which is far away from the driving member 220, is provided with a first notch 321.

It should be noted that the sliding direction of the floating joint 340 in the second notch 322 may be perpendicular to the sliding direction of the pressing element 330 in the first notch 321, and may also be perpendicular to the sliding direction of the slider 320 in the guide slot 311. The floating joint 340 can reduce the difficulty of assembling between the driving mechanism 200 and the guiding mechanism 300, and improve the operation stability of the slider 320.
Further, one end of the second slot 322, which faces away from the pressing member 330, may be provided with a second limiting plate 324, which limits the floating joint 340, and the limiting direction is the same as the retraction direction of the retractable end of the driving member 220.

In the disclosed embodiment, the gripper assembly 400 may include a rotating shaft 410, a scissor gripper 420, and a stop 430. The rotating shaft 410 is a stepped shaft, the large end of the stepped shaft can be fixed on the bottom plate 100 through bolts, and the cross section of the small end of the stepped shaft is circular. The scissors type gripper 420 is composed of two jaws, each jaw is provided with a clamping portion 421, a transmission portion 422 and a connecting portion between the clamping portion 421 and the transmission portion 422, and the connecting portion is provided with a circular through hole matched with the small end of the stepped shaft. Of course, each part of the claw may be an integrated structure, and may also be a structure of inlaying, welding, assembling, and the like, which is not specifically limited in this embodiment of the present invention. The through holes of the two clamping jaws are sequentially sleeved at the small end of the stepped shaft, the two clamping jaws are mutually crossed and symmetrically arranged, one side, deviating from the large end of the stepped shaft, of the small end of the stepped shaft can be fixed with a limiting part 430 through a bolt, the clamping jaws can rotate around the small end of the stepped shaft, and the large end of the stepped shaft is matched with the limiting part 430 to limit the clamping jaws along the axial direction of the stepped shaft.

Preferably, the elastic compression member 440 may be a compression spring.
Further, the connecting portion of two jack catchs can also set up the spacing portion that matches each other, and the cooperation is spacing to the limit of opening of the clamping part 421 of two jack catchs.
Further, the grip 421 of the jaws may be heat treated to increase its hardness and wear resistance.
Further, the opposite sides of the clamping portion 421 of the two jaws may be arc-shaped, so as to increase the contact area with the workpiece, and to increase the clamping force of the clamping device on the workpiece.
