Description

Technical Field

[0001] The utility model relates to a novel welding electrode grinder, in particular to an electrode grinding connector component, belonging to the technical field of electrical welding. Background Art

[0002] At present, the various sub-assemblies of the truck body and most of the auxiliary parts are connected and fixed by welding technology to form a complete cab structure. Most white cabs are welded using resistance welding tongs. When welding 800-1000 welds, the welding strength and appearance quality will gradually decrease with the number of welds. Therefore, the electrode must be ground every 800-1000 welds. The electrode after grinding is restored to its original size, and this operation is repeated continuously to ensure the welding strength and welding appearance quality of all cabs. At present, when grinding the electrode of the welding tongs, the grinding tool used is a special electrode electric grinder. This grinder has a complex structure, and the purchase price and subsequent maintenance costs are very high, so each workshop is only equipped with one, which is far from meeting the welding requirements under the fast production rhythm. In addition, the use of this grinding tool also has certain risks. Since the electrode electric grinder requires power, the power cord must be connected from a long distance every time the equipment is used. The welding site is mostly made of sheet metal, which can easily scratch the power cord. It is highly dangerous and cumbersome, resulting in low grinding efficiency and seriously affecting the production rhythm. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a new welding electrode grinder for the defects of the prior art, which is safe and convenient, ensures the spot welding strength and appearance quality, and improves the grinding efficiency.

[0004] To solve this technical problem, the utility model provides a new welding electrode grinder, including an electrode grinding connector, a blade, a blade mounting bracket, and a connecting screw. The electrode grinding connector is provided with a stepped hole and a square hole inside, one end of the blade is clamped on the blade mounting bracket, the blade mounting bracket is installed in the stepped hole, and the square hole is connected to a bolt tightening machine.

[0005] The end surface of the electrode grinding connector connected to the blade mounting bracket is provided with a through slot having a width equal to the diameter of the stepped hole, and two symmetrical threaded holes are provided on the bottom surface of the through slot for connecting the blade mounting bracket.

[0006] A square groove is provided at the lower end of the electrode grinding connector to facilitate insertion of a wrench for tightening.

[0007] A process hole is provided between the stepped hole and the square hole inside the electrode grinding connector.

[0008] The electrode cap is placed in the internal stepped hole of the electrode grinding connector. The electrode grinding connector assembly is used in conjunction with a bolt tightening machine used on site. When the bolt tightening machine rotates, it drives the electrode grinding connector and the blade and blade mounting bracket thereon. The rotation of the blade realizes the grinding of the electrode cap.

[0009] Beneficial effects: The electrode grinding connector of the utility model is formed in one time and will never be damaged; the processing cost is low, and it can be used in conjunction with the bolt tightening machine used by the team, which is safe and convenient, with high grinding efficiency, ensuring the spot welding strength and appearance quality; the bolt tightening machine is a necessary tool for all welding workshops, with a simple structure and easy maintenance; it uses existing tools and gas sources and has a low cost.
