Abstract

The invention discloses a welding jig for an exhaust manifold heat dissipation auxiliary fixing frame. The welding jig comprises a fixing part, a connecting part and a compressing part all of which are sequentially connected. The fixing part is provided with a guiding groove, the guiding groove is internally provided with a moving block, a first threaded rod penetrates the moving block, the moving block and the first threaded rod are screwed, the moving block can move along the first threaded rod, and the moving block is provided with a fixing plate. A baffle is arranged at one end of the guiding groove. The compressing part comprises a guiding plate, a second threaded rod penetrates the guiding plate, the guiding plate and the second threaded rod are screwed, and a compressing plate is arranged at the end, far away from the guiding plate, of the second threaded rod. According to the welding jig, the fixing part is arranged on a workbench, the problem that during manual welding, fixing is instable, and shaking occurs easily can be solved, meanwhile, the operator can be prevented from being hurt, the movement locus of the compressing plate is fixed, shaking is not prone to occur, and the position of the compressing plate is adjusted conveniently.

Description

technical field [0001] The invention relates to a fixture, in particular to a welding fixture for an exhaust manifold heat dissipation auxiliary fixing frame. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine, and gathers the exhaust of each cylinder into the exhaust manifold, with divergent pipelines. Early automobile engines had low power per unit weight, low fuel combustion efficiency, and the exhaust gas temperature did not exceed 500°C. With the improvement of the efficiency of the automobile engine, the exhaust temperature is increased to 600-650°C. In recent years, the automobile exhaust emission standards have been continuously improved, and the application of catalytic technology and turbocharging technology has significantly increased the working temperature of the exhaust manifold, reaching above 750°C. With the further improvement of engine performance, the working temperature of the exhaust manifold will also i...
