Welding tool fixture for electrolytic bath cathode steel rod and explosion block

Abstract

The invention discloses a welding tool fixture for an electrolytic bath cathode steel rod and an explosion block. The welding tool fixture comprises a fixed frame 5, a rotary hanging hook 6, a welding steel piece box 8, a lifting handle cover 10, an extension rod 3, a first spanner 2 and a second spanner 11; the fixed frame 5 consists of a door-shaped front frame 15, a side plate 17 and a cross beam 16; the rotary hanging hook 6 is fixed up and down through penetrating through one end of the cross beam 16 and a base 19 on the side plate 17; the welding steel piece box 8 is hung on the cross beam 16 through a cylinder pin 9; the first spanner 2 and the door-shaped front frame 15 can enable the explosion block 14 to fix with the fixed frame 5; and the second spanner 11 and the rotary hanging hook 6 can enable the cathode steel rod 7 to fix with the fixed frame 5. The welding tool fixture is convenient for installation, easy to dismount, simple in whole structure and easy to operate, improves the labor intensity and the working environment, is easier to realize automatic welding through matching with a welding machine, and improves the welding efficiency.

Description

technical field [0001] The invention relates to a welding fixture, in particular to a welding fixture for an electrolytic cell cathode steel rod and an explosive block, and belongs to the field of welding technology. Background technique [0002] When installing and overhauling the electrolytic cell of an aluminum electrolysis plant, it is necessary to weld the cathode steel rod and the explosive block through 29 welded steel sheets, that is, to weld 29 layers. The current welding method is manual welding. The cathode steel rod is fixed, and the explosion block is a steel plate formed by explosive welding with the busbar, so the explosion block is movable. External force is required to align and fix the explosive block during welding, which is currently done manually. Because the space is narrow, the welding position is deep, and the environment is harsh, one person assists and one person performs welding, which causes great difficulties for the workers' welding, makes the...
