Problems solved by technology

[0003] However, the current spot welding head rotary spot welding machine has the problem that the spot welding needle is prone to torsion loss due to the torque of the position shift driven by the spot welding head, not only because the spot welding needle needs to be replaced frequently, but also the spot welding The implementation of the welding work is inconvenient, and in the long run, the extra cost of spot welding needle replacement, mold repair, needle coplanar adjustment, needle distortion, etc. will increase the economic burden.

Abstract

The invention relates to a spot welding machine. The spot welding machine comprises a base, two electrode rotating plates, two spot welding pins and two driving mechanisms, wherein the driving mechanisms can apply force to the electrode rotating plates so as to drive the electrode rotating plates to rotate along a rotating shaft, then the spot welding pins can be rotated in an autorotation mode, thus the spot welding pins can be smoothly separated from a workpiece without adhesion during construction, and meanwhile, the loss rate of the spot welding pins can be reduced.

Description

technical field [0001] The invention relates to a spot welding machine, in particular to a spot welding machine with low consumption of spot welding needles. Background technique [0002] The automation of the spot welding machine makes the spot welding work easier and saves time. The traditional automatic spot welding machine uses the spot welding head to drive the spot welding needle to press down, apply force to the workpiece through spot welding and energize to generate an arc, so that the part of the workpiece that is in contact with the spot welding needle is in a molten and viscous state, and then completes the spot welding of the workpiece Work. However, after the traditional automatic spot welding machine completes the spot welding work, the spot welding head directly drives the spot welding needle up to separate from the workpiece, but there is a lack of adhesion to the workpiece. Therefore, some current technologies are improved for this deficiency, so that afte...
