A device for automatically removing electrode caps

Abstract

The invention discloses a device for automatically disassembling electrode caps, which is used in the technical field of electrode cap disassembly and assembly. It includes a cap-removing mechanism and a driving mechanism. The cap-removing mechanism includes a positioning seat and a wedge-shaped pliers. The wedge-shaped pliers have a clamping The clamp end of the electrode cap and the bottom inclined toward the clamp end The positioning seat is provided with a guide surface that can cooperate with the bottom bevel. The driving mechanism can drive the wedge-shaped pliers to move and lift the wedge-shaped pliers upward through the cooperation of the bottom bevel and the guide surface so that the wedge pliers can pass through the pliers. The force that pulls the electrode cap off the electrode rod. This device can automatically and quickly remove the welding gun electrode cap without damaging the cone surface of the electrode rod, so as to solve the problem of electrode rod wear in existing cap removal equipment or devices. It can also adapt to any connection form and any The welding gun with "open mouth" and "throat depth" dimensions can meet the disassembly conditions of the upper and lower electrode caps of the welding gun.

Description

technical field [0001] The invention is used in the technical field of electrode cap disassembly and assembly, and in particular relates to a device for automatically disassembling an electrode cap. Background technique [0002] At present, the joint surface of the welding torch and the electrode cap used in the spot welding of the automobile body-in-white is a conical fit, and the electrode cap as a consumable part needs to be replaced frequently. There are two existing methods for disassembling the electrode cap-manual disassembly and automatic disassembly. Due to the low production efficiency, manual disassembly has been gradually eliminated by the market. The equipment suitable for automatic disassembly is either "twist" or "crowbar". The existing equipment for replacing electrode caps in the market is still There are some defects. Whether it is based on the "twist" principle or the "crowbar" principle, there is a problem of wearing the electrode rod when removing the ca...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a device for automatically dismantling the electrode cap, which can realize automatic and quick disassembly of the electrode cap of the welding torch, and hardly damages the cone surface of the electrode rod, so as to solve the problems existing in the existing cap removal equipment or devices. The problem of wear and tear of the electrode rod can also be adapted to any type of connection, welding torch of any "mouth opening" and "throat depth" size, and can meet the disassembly conditions of the upper and lower electrode caps of the welding torch
