Welding machine

Technical Field

The invention relates to the technical field of welding equipment, in particular to a welding machine.

Background

Welding is the process of joining metal parts using various fusible alloys (solders). The melting point of the solder is lower than that of the material to be welded, so that the welding is completed by intermolecular connection between the surfaces of the parts without melting the parts.

In the process of laser welding, a workpiece needs to be clamped on a workbench, and the workpiece is prevented from moving in the welding process, so that the welding point is prevented from deviating, and the welding quality is influenced. In the prior art, a heavy object is usually adopted and the workpiece is pressed by supplying power through a bolt and a nut. The process of placing or replacing the workpiece is complicated by the compression mode, and the next workpiece can be clamped and welded only by loosening the nut and the bolt one by a worker after the workpiece is welded.

A large amount of welding dust and impurities can be generated in the laser welding process, and the dust and the impurities are harmful to human bodies, can affect the welding quality and even affect the normal work of equipment. Therefore, the welding machine is usually provided with a dust removing mechanism to treat dust generated by welding. In the prior art, a dust collector is generally used to absorb dust and impurities generated by welding from the side edge of the gun head to the gun head. However, it is difficult to thoroughly clean the dust generated by welding in such a dust removal manner.
