Description

Technical Field

[0001] The invention relates to the technical field of engine exhaust pipe production, and in particular to high-pressure cleaning equipment used in an engine exhaust pipe production line. Background Art

[0002] The exhaust nozzle is a key component in the engine's exhaust system, channeling high-temperature exhaust gases from combustion away from the cylinder head and transporting them to components such as the catalytic converter and muffler for final discharge. During production, the nozzle's surface must be thoroughly cleaned of contaminants such as oil, cutting fluid residue, and weld scale to ensure quality subsequent assembly. Currently, production lines primarily utilize high-pressure spray cleaning machines for surface treatment, spraying high-pressure, high-temperature cleaning fluids.

[0003] However, there are two main technical problems with the existing cleaning process:

[0004] 1) Blind spot problem of outer wall cleaning:

[0005] The exhaust pipe needs to be placed on the wire mesh inside the cleaning machine for cleaning. The contact area between the wire mesh and the pipe will form a physical obstruction, resulting in a cleaning blind spot in this area (the typical blind spot width is about 3-4mm), which seriously affects the cleaning uniformity;

[0006] 2) Inner wall cleaning efficiency problem:

[0007] The current placement method makes the exhaust pipe opening in a horizontal direction, which prevents the high-pressure water flow from being directly sprayed into the inner wall of the pipe. The removal rate of pollutants such as anti-rust oil and metal debris remaining in the inner cavity is less than 60%. Currently, an additional dedicated inner wall cleaning process is required, resulting in a reduction of production efficiency by about 30%. Therefore, to address the above problems, a high-pressure cleaning equipment for engine exhaust pipe production line is proposed. Summary of the Invention

The number of transition plates 203 is not necessarily 3, and can be designed according to actual work needs. The exhaust pipes are stored in turn through multiple transition plates 203 to ensure the normal turnover of the exhaust pipes; at the same time, the third electric telescopic rod 201 can adjust the vertical position of the transition plate 203 through the connecting frame 202. When the exhaust pipe on the surface of the stainless steel mesh belt conveyor 9 needs to be transported to the surface of the transition plate 203, the upper surface of the transition plate 203 and the upper surface of the stainless steel mesh belt conveyor 9 are in the same horizontal plane; and the transition plate 203 can be kept in a cleaning state through the flip assembly, so that the exhaust pipe on the surface of the transition plate 203 slides to the surface of the second clamping disk 306.

[0052] As a further improvement of the present invention, Figure 6 and Figure 7 As shown, the flip assembly includes a fixed shell 205 fixedly connected to the frame 5, and a fourth electric telescopic rod 206 is fixedly connected to the inner side of the fixed shell 205.

After the flange opening faces upward, since the liquid sprayed by the spray head 7 is fan-shaped and has a wide spray range, and multiple rows of spray heads 7 for cleaning the exhaust pipe cavity are arranged on the inner side of the frame 5, when passing under the spray head 7, the spray head 7 can make the high-pressure water flow directly spray into the cavity through the flange opening to clean the anti-rust oil, metal debris and other pollutants remaining in the inner cavity, without the need for an additional special inner wall cleaning process, thereby improving the overall cleaning efficiency.
