Description

technical field [0001] The invention belongs to the technical field of spot welding electrode processing machinery, and in particular relates to a semi-automatic electrode cap overlay welding machine. Background technique [0002] The semi-automatic concept of the semi-automatic electrode cap surfacing machine mentioned above refers to: the operator manually places the electrode cap to be surfacing on the electrode cap surfacing machine, and manually adjusts the electrode in the rotating state. The end face of the cap is surfacing, and other actions such as rotating the electrode cap and driving away the electrode cap after surfacing are all automatically completed by the electrode cap surfacing machine. [0003] The electrode cap mentioned above is the spot welding electrode, which is widely used in various welding equipment such as spot welding machines, resistance welding pliers, etc. Under the condition of strength, there is a difference in the resistance calorific valu...

Problems solved by technology

[0008] 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 The shape and size of the bullet with a conical blind hole is small), so it is very troublesome to clamp it reliably unless a complex and unique fixture device is used; If the electrode cap is reliably clamped, the worker needs to make the welding torch frequently move 360° around the electrode cap (circling action) during the melting process, resulting in high work intensity for the worker and unsatisfactory surfacing efficiency; Also because the longer the process of clamping and releasing the electrode cap, the greater the impact on the melting efficiency, so it is difficult to meet the requirements of industrial scale-up production; and because in order to adapt to the requirements of industrial production, more piles have to be invested Welders, which not only cause waste of labor resources, but also lead to increased manufacturing costs
