Technical Field

[0001] The utility model relates to the technical field of composite welding, in particular to a laser arc composite welding fixture. Background Art

[0002] Laser arc hybrid welding combines the advantages of two independent heat sources, laser and arc (such as laser heat source has high energy density, excellent directivity, and transparent medium conduction characteristics, arc plasma has high heat-to-electricity conversion efficiency, low equipment cost and operating cost, mature technology development and other advantages), and avoids the disadvantages of both to a great extent (such as laser energy loss caused by high reflectivity of metal materials to laser, high equipment cost of laser equipment, low electro-optical conversion efficiency, etc., arc heat source has low energy density, poor discharge stability at high speed movement, etc.), and the organic combination of the two has derived many new characteristics (high energy density, high energy utilization rate, high arc stability, low tooling preparation accuracy and surface quality of workpiece to be welded, etc.), making it a new type of welding heat source with great application prospects.

[0003] When welding the workpieces that need to be welded, the two workpieces need to be clamped and fixed to facilitate the subsequent welding of the contact points of the two workpieces. However, when the existing fixing device fixes the workpiece, it is necessary to manually adjust the workpiece during the process of fixing the workpiece, which reduces the efficiency of workpiece welding. For this reason, we designed a laser arc hybrid welding fixture. Utility Model Content

Arranging two bidirectional screw rods facilitates increasing the stability of the movement of the slide plate.

[0008] Preferably, there are two clamps, and rubber layers are embedded on the opposite surfaces of the two clamps. Workpieces are arranged on the opposite surfaces of the two clamps. By setting the clamps, it is convenient to clamp and fix the two workpieces to be welded.
