Therefore, the limiting top end with the reduced width can extend into the process groove on the upper surface of the workpiece to be welded to be matched with each other for limiting.

Furthermore, the welding table is a platform, and the workpiece hole is vertically arranged.

Furthermore, the frame, including the base of lower extreme and connect the bracing piece between base and welding bench.

Furthermore, the limiting top end is arranged along the direction perpendicular to the central line of the threaded hole.

The utility model discloses a frock clamp for laser welding, its advantage embodies in following several aspects:

1. the utility model discloses a frock clamp for laser welding can quick clamping, accurate location, through the top of clamping handle front end, the spacing of hole top locating piece and spacing top, from three dimension quick clamping work piece;

2. the working efficiency of welding workers can be obviously improved, and the number of welding workpieces in unit time is increased;

3. the tool clamp for laser welding has the advantages of light weight, simple structure and low cost.
