Electrode cap overlay welding device with automation function

Abstract

The invention relates to an electrode cap overlay welding device with an automation function and belongs to the technical field of spot-welding electrode manufacturing machinery. The electrode cap overlay welding device comprises a workbench, a pawl shaft driving mechanism, a rotary disc, a rotary disc shaft driving mechanism, a group of electrode cap pivoting support mechanisms, a power transmission mechanism and an automatic electrode cap expelling mechanism, wherein a tubular seat and a guide rail seat are fixedly arranged on the workbench, a push rod yielding chamber is formed at one side, facing to the pawl shaft driving mechanism, of the tubular seat, and the pawl shaft driving mechanism is arranged on the workbench and is matched with the guide rail seat; a rotary disc shaft is fixedly arranged at the center of the rotary disc and supports the tubular seat, and the lower end of the rotary disc shaft extends into a tubular seat chamber; the rotary disc shaft driving mechanism is fixedly connected with the lower end of the rotary disc shaft; the electrode cap pivoting support mechanisms are equidistantly distributed around the edge positions of the rotary disc in a spaced manner; the power transmission mechanism is arranged on the workbench; the automatic electrode cap expelling mechanism is arranged on the workbench and is matched with the electrode cap pivoting support mechanisms. The electrode cap overlay welding device with the automation function has the advantages that the dependence on clamping devices of complicated structures is not required; the intensity of overlay welding operation is reduced; an ideal automatic effect can be embodied; the labor cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of spot welding electrode processing machinery, and in particular relates to an electrode cap surfacing welding device with automatic function. Background technique [0002] The aforementioned electrode cap is the spot welding electrode, which is widely used in various welding equipment such as spot welding machines, resistance welding pliers, etc. The welding equipment that heats the junction of two workpieces to be welded to a plasticized state or partially melted state due to the difference in resistance calorific value, and forms a firm joint under pressure, is used in vehicles, aircraft, ships, electromechanical products, etc. It is widely used in production, even widely used in the production of power transmission and transformation devices such as transformer cooling fins.

AI Technical Summary

Problems solved by technology

[0007] The fused titanium carbide on the surface of the electrode cap mentioned above is surfacing welding titanium carbide (hereinafter the same), in view of the fact that there is no such method used to fused titanium carbide on the end surface of the point electrode cap in the published patents and non-patent literature so far. Due to the technical inspiration of the special device, workers usually hold the welding torch to fuse the transition metal rod (rod-shaped) clamped on the welding torch to the end face of the electrode cap. However, due to the special shape of the electrode cap (like a hollow one It has the shape of a bullet head with a conical blind hole), so it is very troublesome to clamp it reliably unless a complex and unique fixture device is used; Reliable clamping, then the worker needs to make the welding torch frequently move 360° around the electrode cap (circling action) during melting, which leads to the worker's work intensity is high, and the efficiency is not flattering; also because if the clamping and The longer the process of releasing the electrode cap, the greater the impact on the melting efficiency, which makes it difficult to meet the requirements of industrial scale-up production; and in order to adapt to the requirements of industrial production, more surfacing workers have to be invested, resulting in both Waste of labor resources leads to increased manufacturing costs
