In addition, the clamping mechanism 31 may be connected to the inner side of the annular frame 20, or may be connected to the outer side of the annular frame 20, and the present application is not limited thereto, as long as it is ensured that the normal operation of the clamping mechanism 31 is not affected (i.e., the clamping and fixing of the component to be tack-welded by the clamping mechanism 31 is not affected).

The fixed end of the cylinder 312 of the clamping mechanism 31 is connected to the connecting block 311, and the output end is connected to the clamp arm 313. In this way, the air cylinder 312 can drive the clamping arm 313 to rotate, so that the clamping arm 313 approaches to the component to be repair-welded, and then cooperates with the other clamping mechanism 31 to clamp and fix the component to be repair-welded. In the present invention, since the air cylinder 312 needs to drive the clamp arm 313 to rotate, the air cylinder 312 having a rotation function should be selected.

Wherein, optionally, the cylinder 312 is a flat plate cylinder 312. Compared with the circular cylinder 312, the flat-plate cylinder 312 can be mounted in multiple directions, the mounting mode is wider, and the overall volume is smaller than that of the circular cylinder 312, so that the space can be effectively saved. Thus, by applying the flat plate type cylinder 312 to the present application, more clamping mechanisms 31 can be correspondingly mounted on the connecting plate 21 of the ring frame 20, and the applicability of the repair welding clamping machine of the present application to various types of vehicles can be further improved.

Optionally, the cylinder 312 is disposed at an angle to the clamping arm 313. Specifically, the angle α between the cylinder and the clamp arm can be seen in fig. 4.

It should be noted that, referring to fig. 4, an included angle is formed between the cylinder 312 and the clamping arm 313, so that when the cylinder 312 is driven to move and the clamping arm 313 is driven to rotate relative to the cylinder 312, the opening and closing angle of the clamping arm 313 of the clamping mechanism 31 can be further increased due to the included angle α between the cylinder and the clamping arm.

In another aspect of the present application, a welding system is further provided, and the welding system includes the above repair welding clamping machine. Since the structure and the advantages of the repair welding clamping machine are described in detail in the foregoing, they are not described herein again.

The above description is only an alternative embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
