Embodiment Construction

[0013] The working process of a new type of online grinding grinding head developed for burning spot welding electrodes has the following steps:

[0014] (4) Grinding is completed.

[0015] (3) Start the motor 7, drive the belt 4 through the transmission shaft, and the belt 4 drives the drive box 3 to start rotating. As shown in the structure shown in the figure, the grinding box 2 is fixed in the drive box and rotates with the drive box 3. The base of the grinding head 1 Bonded in the grinding box 2 and rotate together with the grinding box 2, and start to grind the burnt spot welding electrode;

[0016] (2) if figure 1 As shown, open the welding tongs equipped with burnt spot welding electrodes, align the burnt upper and lower spot welding electrodes with the grinding area of ​​the grinding head, press the switch of the spot welding machine, and clamp the base of the grinding head 1;

[0017] (1) Adjust the spot welding machine installed with the burnt electrode (the size...

Abstract

The invention provides a novel spot-welding electrode trimming head to replace a traditional trimming blade. The novel electrode trimming head is manufactured by sintering abrasive materials on a metal machine body. In the using process, an upper electrode and a lower electrode directly stretch into the trimming head, and the electrodes can be trimmed into required formed electrodes through rotation of the trimming head. The trimming head is suitable for trimming all resistance spot-welding type equipment electrodes with the technological requirement ranges that the diameter is phi 16, the spherical radian requirement of the electrodes is SR20, and the central welding spot diameter is phi 6-8. The novel spot-welding electrode trimming head is easy to use and convenient and safe to operate, the application cost is greatly reduced compared with the traditional blade, and the novel spot-welding electrode trimming head is suitable for all automobile industries and sheet metal lap welding machining.

Description

technical field [0001] The invention belongs to the technical field of trimming, and in particular relates to a trimming method for burnt spot welding electrodes. Background technique [0002] Due to the continuous improvement of the corrosion resistance requirements of automobiles, galvanized sheet has become one of the indispensable materials in automobile manufacturing. Galvanized steel sheets have strong corrosion resistance, and have replaced traditional cold-rolled steel sheets as body materials in large quantities to improve the corrosion resistance and overall service life of vehicles. The main welding method used in welding the body of galvanized steel sheet is resistance spot welding. During the resistance welding process, a layer of Cu5Zn8 (copper-zinc) alloy will build up on the electrode due to high temperature and pressure. After many times of accumulation, the electrode will be covered by the accumulation layer, which will eventually damage the electrode and...
