Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to an automatic precision spot welding machine which is easy to clamp. Background Art

[0002] Spot welding machine is a mechanical device that adopts the principle of double-sided double-point overcurrent welding. During operation, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other, an instantaneous thermal weld is formed at the two contact resistance points. The welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop without damaging the internal structure of the workpiece being welded.

[0003] However, when fixing the workpiece, the existing devices mostly use simple clamping to squeeze and fix the outer wall of the workpiece. When the workpiece is cylindrical, simple clamping and spot welding will cause a certain amount of shaking, and the workpiece is prone to axial movement, resulting in offset of the spot weld, which in turn affects the spot weld quality.

[0004] Therefore, an automatic precision spot welding machine that is easy to clamp is proposed. Utility Model Content

A plurality of grooves 212 are opened on the side of the L-shaped plate 211. The inner walls of the plurality of grooves 212 are installed with special-shaped rods 213 for fixing the workpiece;

[0034] Specifically, such as Figure 1-7 As shown, a moving plate 201 is fixedly installed on the top surface of the moving device 102, and a moving frame 202 is fixedly installed on the top surface of the moving plate 201.
