A welding fixture for automobile exhaust pipe manufacturing

Abstract

The invention relates to a welding jig for manufacturing automobile exhaust pipes, comprising a base plate, two sets of clamping devices slidingly arranged on the top of the base plate, and a driving device for driving the clamping devices. The two sets of clamping devices are arranged symmetrically, and the clamping devices It includes a moving plate and a horizontal bracket arranged on the side wall of the moving plate. The end of the horizontal bracket is fixedly connected with a clamping head. The clamping head includes a 匚-shaped plate and a first threaded rod screwed on the top of the 匚-shaped plate. The first thread The bottom end of the rod is rotatably provided with a pressing block through a bearing. In the present invention, multiple sets of clamping heads are provided, and through multi-point fixing methods and limiting the position of the muffler, the exhaust pipe is prevented from turning over, and at the same time, it is also ensured that the exhaust pipe will not be misplaced during welding; the present invention uses a bidirectional motor and The two-way screw cooperates to drive the two sets of clamping devices to approach or move away synchronously. According to the scale pointed by the two sets of pointers, the distance moved by the moving plate can be observed, and then the distance between the two sets of exhaust pipes can be determined.

Description

technical field [0001] The invention relates to the technical field of welding fixtures, in particular to a welding fixture for manufacturing automobile exhaust pipes. Background technique [0002] The exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter that controls the emission of engine pollutants is also installed in the exhaust system. The exhaust The pipe generally includes a front exhaust pipe and a rear exhaust pipe. For some cars with relatively large displacement or some sports cars, because the engine power and energy consumption are relatively large, and the waste generated during this period is relatively large, often one exhaust pipe cannot completely solve the problem, so it will be Then install an exhaust pipe. The advantage of this is that it can quickly help the vehicle to clean up the exhaust. [0003] The two exhaust...

AI Technical Summary

Problems solved by technology

[0003] The two exhaust pipes are fixed by welding, but the existing welding fixture has the following disadvantages: 1. When the welding fixture clamps the two exhaust pipes, it cannot ensure that the ends of the two exhaust pipes are even. Misalignment may occur during the welding process; 2. The distance between the two exhaust pipes of different models is different, and the distance between the two exhaust pipes cannot be seen when the two exhaust pipes are moving
