Technical Field

The utility model relates to a technical field of anchor clamps, in particular to clamping jaw for laser cutting.

Background

Laser cutting is widely used in metal processing in manufacturing enterprises because of its characteristics of reducing processing time, reducing processing cost and improving workpiece quality. When the laser cutting equipment is used for cutting square pipe workpieces, the square pipe workpieces need to be clamped by the special clamp, so that the stability of the square pipe workpieces is guaranteed during cutting, and the clamp is arranged on the moving mechanism, so that the square pipe workpieces can be driven to move to realize feeding, and the cutting work is smoothly carried out.

In enterprises, a three-jaw chuck type clamp is generally adopted to clamp a workpiece, but the three-jaw chuck type clamp is difficult to apply to a square pipe workpiece, and the periphery of the workpiece needs to be clamped when the workpiece is clamped. And in actual operation there are the following problems: square pipe work piece need set up support piece before the cutting point of laser cutting equipment when the cutting to long banding square pipe work piece can be placed, thereby avoid relying on anchor clamps to guarantee steadily, because support piece's existence, for avoiding anchor clamps and support piece collision when moving mechanism feeds, consequently need stop motion in advance, and the final section that finally leads to square pipe work piece can't cut or the clout is longer, causes unnecessary extravagant.
