Centering clamp for friction welding steel claw

Abstract

The invention relates to a centering clamp for a friction welding steel claw. The centering clamp for the friction welding steel claw can enable clamping force to be evenly distributed, reduce welding vibration and improve clamping efficiency and welding efficiency, so that electrolytic aluminum welding quality is improved, welding time is shortened, and economic benefits of enterprises are improved. The clamp comprises a clamp body (1), steel claw cores (3), a pull rod (6) and a steel claw (7), before friction welding, the steel claw is placed in an inner hole of the clamp body, the right side walls of the steel claw cores and the inner hole of the clamp body have the same taper, the inner hole surface formed by the inner surfaces of the steel claw cores makes contact with the outer circle of the steel claw, and the effects of positioning and clamping are achieved during clamping; and the left part of each steel claw core is connected with the pull rod which is connected with an oil cylinder. In the welding process, the steel claw cores are driven by the pull rod to move leftwards, and the multiple steel claw cores move leftwards and contract towards the center in parallel to clamp the steel claw; and after welding is completed, the oil cylinder pushes the pull rod to enable the steel claw cores to move rightwards, and the steel claw is loosened.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a centering fixture for friction welding steel claws, which is mainly used for positioning and clamping when the friction welding electrolysis guide rod steel claws are welded. Background technique [0002] The electrolytic anode in the electrolytic aluminum equipment is composed of carbon blocks, steel claws, and aluminum guide rods. The steel claws will be ablated or deformed during the electrolytic aluminum liquid process. After cutting off the steel claws, re-weld the new steel claws to the steel Claws on steel beams. [0003] At present, during the welding process of steel claws, due to the limitation of the fixture structure and the dimensional deviation of the outer surface of the steel claws, the clamping area is small, and the clamping force is unevenly distributed and weak, resulting in the welding process. The vibration in the machine will affect the welding...
