Device for automatically dismounting electrode caps

Abstract

The invention discloses a device for automatically dismounting electrode caps and is used for the technical field of mounting and dismounting of the electrode caps. The device comprises a cap dismounting mechanism and a driving mechanism; the cap dismounting mechanism comprises a positioning seat and wedge-shaped tongs; the wedge-shaped tongs comprise a tong end capable of clamping the electrode caps and a bottom inclined surface inclining towards the tong end; a guiding surface matched with the bottom inclined surface is arranged on the positioning seat; and the driving mechanism can drive the wedge-shaped tongs to move and provide the acting force to lift the wedge-shaped tongs upwards so as to separate the electrode caps from electrode poles by the aid of the tong end through matching of the bottom inclined surface with the guiding surface. By the aid of the device, the electrode caps of various welding guns can be dismounted automatically and quickly, conical surfaces of the electrode poles are almost not damaged, the problem of abrasion of the electrode poles by existing cap dismounting equipment or devices is solved, and meanwhile, the device can adapt to any joining manners and welding guns with opening and throat depth sizes and can meet dismounting conditions of upper and lower electrode caps of the welding guns.

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...

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
