Vehicle exhaust pipe hot end welding fixture tool

Abstract

The invention relates to the technical field of vehicle machining and production, in particular to a vehicle exhaust pipe hot end welding fixture tool. The vehicle exhaust pipe hot end welding fixturetool comprises a base, an exhaust pipe is arranged at the upper end of the base, a clamping block is arranged on the rear side of the upper end of the base in a sliding mode, side plates are vertically welded to the front end and the rear end of the left side of the upper end surface of the base, a hydraulic cylinder and a fixing clamp are correspondingly arranged on the inner sides of the pair of side plates in sagittal symmetry, and the end part of a telescopic rod of the hydraulic cylinder is fixedly arranged on the rear side of the clamping block. The vehicle exhaust pipe hot end weldingfixture tool has the beneficial effects that the clamping block pushed by the hydraulic cylinder is arranged, so that an exhaust pipe is fixedly clamped, meanwhile, an inserting rotating rod with a limiting clamping groove is utilized, so that the clamping force is limited, and through cooperation of the rotating rod capable of rotating, the inclination angle of the exhaust pipe device is adjusted; and through cooperation of a rotating groove and a rotating arc plate, autorotation adjustment of the exhaust pipe after being clamped and fixed is realized, so that circumferential rotating weldingis realized in the welding process, manual rotation is avoided, and therefore the welding and fixing precision is greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicle processing and production, in particular to a welding jig for the hot end of a vehicle exhaust pipe. Background technique [0002] The exhaust pipe is installed between the engine exhaust manifold and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, facilitating installation and prolonging the life of the exhaust muffler system. [0003] Most of the existing automobile exhaust pipes are installed by welding. However, when welding and clamping, the existing devices lack a position adjustment device, which requires manual low-precision adjustment, which not only consumes manpower, but also The quality is poor. The exhaust pipe is a hollow pipe with a thin outer wall. When clamping, the clamping force is difficult to control, which may easily cause deformation of the outer wall of the pipe. [0004] Therefore, a vehicle exhaust pipe hot end ...

Problems solved by technology

[0003] Most of the existing automobile exhaust pipes are installed by welding. However, when welding and clamping, the existing devices lack a position adjustment device, which requires manual low-precision adjustment, which not only consumes manpower, but also The quality is poor. The exhaust pipe is a hollow pipe with a thin outer wall. When clamping, the clamping force is difficult to control, which may easily cause deformation of the outer wall of the pipe.

[0004] To this end, a vehicle exhaust pipe hot end welding fixture tool is provided to solve the problem of clamping and adjusting the exhaust pipe
