Mould-repair replacing equipment for electrode caps of welding machine

Abstract

The invention belongs to the technical field of welding equipment, in particular to mould-repair replacing equipment for electrode caps of a welding machine. The mould-repair replacing equipment comprises an electrode cap mould repair device and a supporting part for mounting and supporting the electrode cap mould repair device, wherein the electrode cap mould repair device comprises a transmission body as well as a motor, a driven gear and a mould repair gear mounted on the transmission body; the motor drives the driven gear to rotate; the driven gear drives the mould repair gear to rotate; a mould repair plate is mounted in the mould repair gear; a blade is arranged on the mould repair plate; and the mould repair plate rotates along with the mould repair gear, so that the blade carries out cutting and mould-repair on the electrode caps. The mould-repair replacing equipment is used for carrying out mould repairing on the electrode caps on a pair of electrodes of an automatic welding machine; the completely scrapped electrode cap can be automatically dismounted, and a brand-new electrode cap can be automatically replaced; the electrode caps of the two electrodes can be mounted, dismounted or subjected to mould-repair simultaneously; and the end surfaces of the electrodes subjected to mould-repair are concentric and fitted, so that the mould-repair speed is high.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a mold repairing and replacing equipment for electrode caps of welding machines, which is used to repair the molds of the electrode caps on a pair of electrodes of an automatic welding machine, and can automatically replace completely discarded electrode caps. Disassemble, and automatically replace a new electrode cap. Background technique [0002] The electrode cap is a kind of welding electrode, which is used for welding resistance welding equipment, such as fixed spot welding machine, hanging spot welding machine, manipulator spot welding machine and robot spot welding machine, etc., because it is set on the electrode connecting rod, so called the electrode cap. Most of the materials are chrome-zirconium copper, and there are also dispersed copper. After welding for a certain number of times (generally 1000-1200 points), it needs to be repaired or repla...

AI Technical Summary

Problems solved by technology

[0004] As the electrode cap is so easy to wear and tear, the traditional way to deal with it is to directly replace the electrode cap

It is also very difficult to replace the electrode cap, or it will be laborious and unsafe to disassemble it manually with pliers

There is also a method of repairing the electrode caps by manual grinding in order to save costs, but the effect of the repairing is not very satisfactory, and the shape of the electrode caps after the repairing is also seriously deformed, making t...
