Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0018] see figure 1 , the tooling structure is divided into three parts: manifold transition section 1, intermediate connecting section 2 and receiving adjustment section 3. The exhaust manifold adapter flange 14 on the manifold transition section 1 and the engine exhaust manifold outlet flange The first disc flange 12 is connected to the first spherical flange 11, the second spherical flange 8 is connected to the second disc flange 7, and the air outlet interface disc 4 is connected to the air outlet. The first to third bellows 13, 10, 6 are the same parts. The first and second spherical flanges 11, 8 are of the same type. The first and second disk flanges 12, 7 are of the same kind.

[0019] see figure 2 , Schematic diagram of the disc flange. The disc flange is in the shape of a disc as a whole, four arc-shaped holes 15 are symmetricall...

Abstract

The invention provides a highly versatile engine exhaust tooling which is simple in structure, easy to use, and can be shared by various engines. It is used in the bench test of automobile engines, and saves the time and cost of repeatedly manufacturing the tooling in the bench test of the engine. The exhaust tooling is composed of three sequentially connected manifold transition sections, intermediate connecting sections and receiving adjustment sections. Use the special exhaust port interface plate and the special plate-shaped flange to realize the change of the connection angle between the transition section of the manifold and the intermediate connecting section and between the intermediate connecting section and the adjusting section; Changes; using the bellows, each flange surface can be adjusted in a small angle, so as to ensure the cooperation between each flange surface. Angle and distance adjustment can be realized by using the engine exhaust tooling, so it can be used together by various engines.

Description

technical field [0001] The invention relates to a highly versatile engine exhaust tool that can be used in engine bench tests. Background technique [0002] When carrying out the engine bench test, it is necessary to lead the exhaust to a fixed exhaust outlet, and usually a tooling exhaust pipe is made for the engine. The current practice is to first measure the relevant dimensions of the engine on the bench, and then cut and weld different pipes to obtain the exhaust tooling for a specific engine. Due to the different lengths and connection faces of the exhaust manifolds of different engines, the required exhaust tooling is also different, so a corresponding exhaust tooling must be made for each engine. This method is time-consuming and labor-intensive, and there are too many exhaust tooling, which is inconvenient to store. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a highly versatile engine exhaust tooli...
