Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures for spot welding machines, and is a positioning fixture for spot welding machines. Background Technology

[0002] A spot welding machine is a mechanical device that uses the principle of double-sided, double-point overcurrent welding. During operation, two electrodes press on the plate-shaped workpiece, causing the two layers of metal to form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, it forms an instantaneous thermal fusion at the two contact resistance points. The welding current also flows instantaneously from the other electrode along the two plate-shaped workpieces to this electrode to form a circuit, without damaging the internal structure of the plate-shaped workpiece being welded.

[0003] During the spot welding process of plate-shaped workpieces, it is necessary to manually hold the plate-shaped workpiece to adjust the spot welding position. This can easily lead to inaccurate spot welding positions, resulting in misalignment of the spot welds and affecting the subsequent use of the plate-shaped workpieces. Utility Model Content
