Description

Technical Field

[0001] The utility model relates to the field of electrode cap disassembly tools, in particular to a spot welder electrode cap disassembly tooling. Background Art

[0002] The electrode and the electrode cap of a spot welder are connected in a tapered surface matching form with the same taper. During the welding process, under the action of heat, the electrode and the electrode cap will be connected more and more firmly. Since the electrode is greatly worn during the welding process of the spot welder, the electrode cap needs to be frequently replaced in actual working conditions. However, due to the firm connection between the electrode and the electrode cap, it is difficult to disassemble the electrode cap. The existing disassembly method is to use pliers to screw off the electrode cap, but if the force is not applied properly, it is easy to cause the deformation of the electrode taper. When reinstalled and used, the electrode cap is likely to be loosely connected and fall off. At the same time, since a large amount of heat is generated during the welding process of the spot welder, a coolant pipeline is provided in the electrode and the electrode cap for cooling. If the connection tapered surface of the electrode or the electrode cap is damaged or the electrode cap is deformed during the disassembly process of the electrode cap, it will also cause the problem of coolant leakage when used again. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a spot welder electrode cap disassembly tooling to solve the problems mentioned in the background art.

[0004] To achieve the above purpose, the technical solution adopted is: a spot welder electrode cap disassembly tooling, including an upper clamp body, a lower clamp body, and connection bolts and arc-shaped elastic pieces connecting the two. The arc-shaped elastic piece is installed in the middle of the upper and lower clamp bodies through fixing screws; a upper clamp connection bushing integrally formed with the upper clamp body is provided at the front of the upper clamp body, and a lower clamp connection bushing integrally formed with the lower clamp body is provided at the front of the lower clamp body. The connection bolt passes through the upper clamp connection bushing and the lower clamp connection bushing; the front ends of the upper clamp body and the lower clamp body are U-shaped jaw parts. Among them, the jaw part of the upper clamp body is the electrode side jaw, and the jaw part of the lower clamp body is the electrode cap side jaw. The electrode side jaw is larger than the electrode cap side jaw. The front ends of the jaw parts are all L-shaped groove structures for inserting into the tapered connection part between the electrode and the electrode cap; handles are provided at the rear parts of the upper and lower clamp bodies. In the natural state, the electrode side jaw and the electrode cap side jaw are close to closing, and in the working state, the jaw parts of the electrode side jaw and the electrode cap side jaw open.

[0005] Preferably, a fixing plate is fixedly connected to the outside of the L-shaped groove, which enhances the clamping stability of the jaw part.

[0006] Specifically improved, the arc-shaped elastic piece is made of elastic material and is not prone to plastic deformation after repeated use.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The structure of the utility model is simple and the operation is convenient. It preferably solves the problem that the electrode cap is not easily detached from the electrode, and it is not necessary to place the electrode in a specific device to complete the disassembly work, thus saving working hours.
