Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, fig. 1 is a schematic structural diagram of the present invention.
The utility model provides a pair of argon arc welding machine's ground clamp, including first splint 1, second splint 2, pivot 3, torsional spring 4 and application of force subassembly 5, first splint 1 links to each other through pivot 3 with second splint 2, has seted up first pinhole on the first splint 1, has seted up on the second splint with first pinhole complex second pinhole, and pivot 3 passes first pinhole and second pinhole. During clamping or unclamping of a workpiece, the first clamping plate 1 and the second clamping plate 2 rotate about the rotating shaft 3.
As shown in fig. 1, the torsion spring 4 is sleeved on the periphery of the rotating shaft 3, one end of the torsion spring 4 abuts against the first clamping plate 1, the other end of the torsion spring 4 abuts against the second clamping plate 2, under the normal state of not clamping the workpiece, the distance between one end of the torsion spring 3 and the other end of the torsion spring is farthest, in the process of opening the clamping opening to clamp the workpiece, one end of the torsion spring 3 and the other end of the torsion spring are slowly close to each other until clamping the workpiece, and when loosening the workpiece, one end of the torsion spring 3 is separated from the other end of the torsion spring.
