Automatic welding machine

Abstract

The invention discloses an automatic welding machine, which comprises a seat and a worktable arranged on the seat. X-axis guide tracks are arranged at two ends of the worktable, a portal frame capable of moving front and back is arranged on the X-axis guide tracks, a Y-axis guide track is arranged on the portal frame, a Y-axis seat capable of moving left and right is disposed on the Y-axis guide track, a Z-axis guide track is arranged on the Y-axis seat and provided with a Z-axis seat capable of vertically moving, a U-axis seat is disposed on the Z-axis seat, a welding gun seat capable of rotating horizontally is disposed on the U-axis seat, and a welding gun angle adjusting mechanism capable of swinging on a perpendicular plane is disposed on the welding gun seat and provided with a welding gun. During operation, after definite setting of the angle adjusting mechanism is finished, an operator only needs to place a workpiece on a positioning fixture, then the welding machine can automatically finish a welding process, the workpiece is taken down after welding is finished, and the operator only needs to carry out feeding and discharging operations. Besides, as production factors are stable and repeatability is good in a welding process, quality stability can be guaranteed while work efficiency is improved.

Description

technical field [0001] The invention relates to a welding machine, in particular to a four-axis automatic welding machine. Background technique [0002] In the existing technology, it is often necessary to weld two workpieces together to form a workpiece or product. Usually, there are two welding methods: manual welding and machine welding. The shapes of the two workpieces to be welded are ever-changing, and the shape of the joint line of the two workpieces is also ever-changing. , such as the welding of tool handles, etc. [0003] Manual welding has the advantage of flexibility and adaptation, but manual welding has many limitations, and the labor intensity of workers is high and the working environment is harsh; machine welding is currently more suitable for dealing with those workpieces with relatively regular shapes, and for the situation where the joint line weld is a complex space curve , very difficult or even impossible to handle.
