Table device for polishing electrode caps

Abstract

The invention relates to a table device for polishing electrode caps, which is used for solving the problems existing in the process of polishing the electrode caps of resistance welding tongs. The device comprises a motor and speed reduction mechanism, a polishing cutter, an electrode cap installing and pushing mechanism, a discharging mechanism, a worktable and an electric control system, wherein the motor and speed reduction mechanism is arranged below a table top of the worktable and connected with the polishing cutter; the polishing cutter is provided with two sets of blades for supporting the simultaneous polishing of left and right electrode caps, is positioned at the middle position of the table top of the worktable, and is arranged in an axial floating mode; and each of the electrode cap installing and pushing mechanism and the discharging mechanism comprises two eudipleural parts and is arranged on the table top of the worktable. The device has the characteristic of high automation degree, is convenient to operate and maintain, can ensure the polishing quality of the electrode caps, improves the polishing efficiency of the electrode caps, and is maintenance equipment necessary for a welding production line.

Description

technical field [0001] The invention relates to a grinding device, in particular to an automatic grinding device for an electrode cap. Background technique [0002] Resistance welding tongs is an important equipment for car body welding in automobile manufacturing enterprises. It uses the characteristics of different resistance heating values ​​of different materials (copper and iron) under the same current intensity conditions to heat the joint of two welding workpieces to a plastic state or local It is a welding equipment that forms a firm joint under pressure in a molten state, and is characterized by compact structure, simple operation, and high welding efficiency. At present, the electrode ends of this kind of welding equipment generally use detachable standard electrode caps. In order to ensure the welding quality, the electrode caps whose end surface wear exceeds the specified requirements must be ground and replaced in time. [0003] The existing electrode cap grind...

AI Technical Summary

Problems solved by technology

Although this kind of equipment is cheap and simple in structure, manual operation is required throughout the whole process, and the efficiency is low. Moreover, due to the heat generated by the friction between the grinding tool and the electrode cap, the removal of the electrode cap after grinding is laborious, and there is a hidden danger of scalding the operator's hands.

The other type is semi-automatic grinding equipment, whose working principle and operation method are the same as the former, but it is equipped with a disc grinding seat, which can place multiple electrode caps at the same time, and enter the grinding position by rotation. The crowbar automatically disassembles the electrode cap; the disadvantage of the semi-automatic grinding equipment is that the rotation is not concentric, which may easily cause partial grinding of the electrode cap, and the crowbar blanking may easily damage the mounting surface and affect normal use.
