Description

Welding clamp electrode cap removal wrench

technical field

The utility model belongs to a special tool for removing electrode caps, in particular to a wrench for removing electrode caps of welding tongs in resistance welding.

Background technique

The electrode cap of the welding tongs in resistance welding is a bullet-shaped cylinder with a smooth surface. After it is connected to the electrode rod, it is almost impossible to disassemble it without damaging the parts, that is, between the electrode cap of the welding tongs and the electrode rod. Disassembly is extremely difficult.

Contents of the invention

The purpose of this utility model is to provide a simple in structure and easy to use wrench for removing electrode caps of welding tongs in view of the above deficiencies.

The utility model is realized in the following way: it is composed of a card plate with a connecting groove and a sleeve hole, and a handle with an eccentric cam at one end, wherein the connecting groove communicates with the sleeve hole, and the eccentric cam is located in the connecting groove and is connected to the clamp through the pin shaft. board connection.

The utility model can conveniently and easily remove the electrode cap of the welding tongs through the clamping plate and the eccentric cam, and can solve the problem of difficult disassembly of the cylindrical workpiece with a smooth surface. The utility model has the advantages of simple structure, convenient use and portability.

Description of drawings

Fig. 1 is the structural representation of the utility model.

FIG. 2 is a schematic cross-sectional view along line A-A of FIG. 1 .

In the figure: 1—connection slot, 2—hole, 3—clamp plate, 4—eccentric cam, 5—handle, 6—pin shaft, 7—electrode cap of welding tongs.

Detailed ways

Further illustrate the utility model below in conjunction with accompanying drawing and embodiment.

Embodiment: the clamping plate 3 is provided with interconnecting connecting groove 1 and sleeve hole 2, and one end of the handle 5 is provided with an eccentric cam 4, wherein the eccentric cam 4 is located in the connecting groove 1 and is connected to the clamping plate 3 through a pin shaft 6. Become the utility model.

When using, first set the sleeve hole 2 on the electrode cap 7 of the welding tongs to be disassembled, then turn the handle 5 so that the eccentric cam 4 firmly clamps the electrode cap 7 of the welding tongs in the sleeve hole 2, and finally tap the The clamping plate 3 can easily remove the electrode cap 7 of the welding tongs.
