Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a clamp for welding machines. Background Art

[0002] Welding machine fixtures can firmly fix the workpiece on the welding machine, allowing the operator to complete the welding work more quickly and accurately. Fixtures can help reduce adjustment and alignment time and improve production efficiency. Fixtures can ensure that the workpiece maintains a stable position and angle during the welding process. They can eliminate vibration and displacement, reduce the occurrence of welding flaws and defects, and thus improve welding quality. Some workpieces have complex structures and are difficult to weld by hand alone. Fixtures can provide additional support and positioning to help operators complete delicate operations during the welding process and ensure welding quality and accuracy.

[0003] Existing welding machine fixtures usually consist of a clamping device, a supporting structure, and an adjustment mechanism. When clamping and fixing the welding workpiece, the welding workpiece needs to be placed on a support, and then clamped and fixed by the clamping device, and the position, angle and size of the fixture are adjusted by the adjustment mechanism to adapt to different workpiece requirements. The welding workpiece cannot move by itself after being clamped and fixed. When the welding position needs to be changed, the welding position cannot be quickly adjusted according to the needs, which is inconvenient. In addition, the clamping device does not have a short-distance buffer structure, and the welding workpiece is not prestressed when fixed, and the reinforcement is not stable enough.
