Projection welding nut welding clamp

Abstract

The invention relates to a welding clamp for projection welding nuts, which is used for solving the welding problem of a sheet metal component. The welding clamp comprises a clamp seat, a clamping mechanism, an upper clamping piece, a lower clamping piece, an upper press block and a lower press block, wherein the position of the upper press block corresponds to the position of the lower press block from top to bottom, the lower clamping piece is fixed on the clamp seat, the lower press block is fixedly connected with the lower clamping piece, and the lower press block is provided with a nut positioning pin coated with an insulating layer; the upper clamping piece is connected with the clamping mechanism and fixedly connected with the upper press block, an insulation sheet is arranged between the upper press block and the upper clamping piece, and a lower insulation sheet is arranged between the lower press block and the lower clamping piece. The welding clamp can position and clamp a projection welding nut and a sheet metal component and directly weld the projection welding nut on the sheet metal component on a positioned work station by utilizing a suspension spot welder. Due to the adoption of the clamp, the technique process is simplified, a middle transportation link is saved, and the clamp plays an obvious role in enhancing the work efficiency and saving the carrying space.

Description

technical field [0001] The invention relates to a fixture, in particular to a special fixture for positioning projection welding nuts and sheet metal parts in automobile manufacturers, and then directly welding them with a suspension spot welder. Background technique [0002] In the automobile manufacturing plant, when the projection welding nut needs to be fixed as an ordinary loading part and the body, the current process is as follows: first, the projection welding nut is welded on the sheet metal part to be fixed by a projection welding spot welding machine, Then transport the sheet metal parts welded with projection welding nuts to each welding station of the suspension spot welding machine, and the welding personnel of the suspension spot welding machine will use the suspension spot welding machine to carry out spot welding connection of each sheet metal part. Due to the lack of suitable tooling, the welding station for projection welding nuts and the welding station f...

AI Technical Summary

Problems solved by technology

Due to the lack of suitable tooling, the welding station for projection welding nuts and the welding station for sheet metal parts are operated separately, which reduces work efficiency, increases intermediate transportation links, and occupies semi-finished product handling space and transportation personnel.
