The utility model can weld irregular welds between plates by controlling the multi-directional movement and adjustment of the welding mechanism and the grinding mechanism, and can grind while welding, and can work simultaneously on the same machine for welding and grinding, which effectively solves the problem that the welding port position often produces some unevenness and burrs during the welding process, and is transferred to the grinding equipment for grinding during processing, which not only adds an additional process, but also increases the labor intensity of production workers.

[0004] However, when the above-mentioned device is in use, the grinding plate moves downward under the movement of the piston rod of the third cylinder so that the welding part of the plate can be fully polished. Due to the staff's misoperation, the piston rod of the third cylinder may move downward too much, resulting in excessive polishing of the welding part of the plate. Therefore, external grinding equipment is needed to prevent excessive polishing. Utility Model Content
