Description

Technical Field

[0001] The utility model relates to the technical field of straight pipes of mufflers, in particular to a universal welding tooling for straight pipes of mufflers. Background Technique

[0002] An automobile muffler is mainly used to reduce the noise generated when the engine of a motor vehicle works. The principle is that the automobile exhaust pipe is composed of two pipes with different lengths. These two pipes are first separated and then converged. Since the difference in the lengths of these two pipes is equal to half of the wavelength of the sound wave emitted by the automobile, when the two sound waves are superimposed, interference occurs and they cancel each other out, weakening the sound intensity and reducing the sound transmitted, thereby achieving the effect of silencing.

[0003] A welding tooling is a set of flexible welding fixtures for fixing, clamping, and positioning, mainly used for welding various weldable materials, welding of large, medium, and small-sized materials, and small and medium batch production. Three-dimensional flexible welding tooling is widely applicable to steel structures, manufacturing of various vehicle bodies, rail transit welding, etc., as well as welding and inspection systems.

[0004] When a muffler needs to be installed on a square pipe, a welding tooling is required to fix and clamp the square pipe. When clamping square pipes of different sizes, some toolings can only be used to clamp mufflers of one model height. This method causes that when people encounter mufflers with a height higher than the original size in daily life, they cannot be used, affecting the use. Content of the Utility Model

[0012] As a further improvement of the above technical solution: limit the position of the handle at the upper end through the connecting shaft. When people manually lift the handle upward, the handle rotates around the connecting shaft at the uppermost end and the limiting block as the center.

[0013] Preferably, the connecting shaft in the middle passes through the mounting bracket, the handle and the fixed column, and the connecting shaft in the middle is rotatably connected to the handle, and the connecting shaft in the middle is fixedly connected to the mounting bracket and the fixed column.

[0014] As a further improvement of the above technical solution: connect the mounting bracket and the fixed column through the connecting shaft at the lower end. When the handle is pushed upward, it will drive the fixed column to move upward.

[0015] Preferably, the upper end of the handle is arranged in an L-shaped clamping plate shape, and the upper end of the handle is located outside the fixed column and at one end where two mounting brackets are adjacent. The handle is slidably connected to the two mounting brackets.

[0016] As a further improvement of the above technical solution: this shape is convenient for lifting the fixed column upward when the handle is lifted during use.

[0017] The utility model has the following beneficial effects:

[0018] Compared with the prior art, for this universal welding tooling for the straight pipe of the muffler, by setting the clamping plate, the fixing plate, the handle and the connecting shaft, during use, the height of the clamping plate can be changed by pressing down and pushing up the handle, so as to fix mufflers with different heights in a square shape on the workbench through this device, facilitating subsequent processing, and improving the clamping of mufflers with different heights when using this tooling.
