Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to a positioning fixture for a spot welding machine. Background Art

[0002] Spot welding machine is a mechanical equipment that adopts the principle of double-sided double-point overcurrent welding. When working, 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 through the other electrode, an instantaneous heat weld is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the workpiece being welded.

[0003] At present, when spot welding is performed on a spot welding machine by moving the workpiece by hand, it is difficult to control the position between spot welds, resulting in uneven distribution of weld spots.

[0004] The reason for this problem is that currently spot welding is mainly performed by continuously touching the workpiece with a metal rod on a spot welding machine. Since the spot welding position needs to be adjusted by constantly moving the workpiece by hand, it is difficult to control the position between spot welds when the workpiece is moved by hand, resulting in disordered and uneven distribution of welds on the workpiece, which can easily affect the performance of the workpiece. In view of the shortcomings of the existing technology, we propose a spot welding machine positioning fixture to solve the above problems. Utility Model Content
