Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a camshaft rear bearing cover cleaning device. Background Art

[0002] As we all know, the camshaft is a component in piston engines. Its function is to control the opening and closing of the valves. Although the camshaft speed in a four-stroke engine is half that of the crankshaft (in a two-stroke engine, the camshaft speed is the same as the crankshaft), it is generally still very high and must withstand high torque. Therefore, the design of the camshaft requires high strength and support. The material is generally special cast iron, and forgings are occasionally used. Because the valve movement pattern is related to the power and operating characteristics of an engine, camshaft design plays a very important role in the engine design process.

[0003] The existing camshaft rear bearing cover, such as the engine camshaft bearing cover disclosed in announcement number CN101906999B, has an irregular shape, and the shape of the camshaft bearing cover of each engine is different. The existing camshaft rear bearing cover cleaning device is a sealed container, the camshaft rear bearing cover is placed inside the container, and then a high-pressure cleaning medium (such as cleaning liquid, high-temperature steam, etc.) is injected into the container to achieve the purpose of cleaning the camshaft rear bearing cover.

[0004] In order to accommodate camshaft rear bearing caps of different sizes and models, the internal volume of the existing camshaft rear bearing cap cleaning device is relatively large. However, in actual use, the following deficiencies exist:

[0005] 1. Since the internal volume of the existing camshaft rear bearing cover cleaning device is large, the amount of cleaning medium required is also increased, which wastes a lot of cleaning medium and increases the cost of use;

[0006] 2. Since the internal volume of the existing camshaft rear bearing cover cleaning device is relatively large, the cleaning medium flows into the larger space, and the flow rate of the cleaning medium inside it will be significantly reduced, affecting the flushing effect on the cleaning parts. Utility Model Content

[0009] (2) Technical solution

[0010] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a camshaft rear bearing cover cleaning device, comprising several detachable shells, each of which is provided with an elastic sealing assembly inside, and after several of the shells are merged, the several elastic sealing assemblies inside them form a cleaning chamber for accommodating cleaning parts, and each of the shells is equipped with several driving assemblies for driving the deformation of the elastic sealing assembly, and the shell is provided with several inlet pipes and several sewage pipes.

[0011] Furthermore, one end of each of the driving components is provided with a connector connected to the elastic sealing component, and the other end of each of the driving components is provided with a limiting component.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 The utility model provides a camshaft rear bearing cover cleaning device, comprising several detachable shells 1, each of which is provided with an elastic sealing assembly 2 inside. After the several shells 1 are merged, the several elastic sealing assemblies 2 inside them form a cleaning chamber 9 for accommodating a cleaning piece 8. Several driving assemblies 3 are installed on each shell 1. By moving the driving assembly 3 to deform the elastic sealing assembly 2, the cleaning chamber 9 formed by the elastic sealing assembly 2 is adapted to the cleaning piece 8. Therefore, the cleaning chamber 9 can adapt to cleaning pieces 8 of different models and sizes, thereby improving practicality and reducing the volume of the cleaning chamber 9, effectively reducing the waste of cleaning medium, and the cleaning medium flows in the reduced space, and its flow rate will be significantly improved, thereby preferably improving the flushing effect of the cleaning medium. Several inlet pipes 6 and several sewage pipes 7 are provided on the shell 1.

[0027] One end of each driving assembly 3 is provided with a connecting piece 5 connected to the elastic sealing assembly 2 , and the other end of each driving assembly 3 is provided with a limiting assembly 4 , which prevents the driving assembly 3 from entering the housing 1 .

[0028] In the first embodiment, the driving component 3 is a smooth support shaft, and the support shaft and the connecting member 5 are fixedly connected. The support shaft is squeezed or offset by an external object to keep the position of the support shaft unchanged so as to keep the cleaning chamber 9 unchanged. For example, a heavy object is used to support the support shaft, or a top screw is provided on the shell 1 to squeeze the support shaft using the top screw.

[0029] In the second embodiment, the driving component 3 is a screw, and the screw and the connecting member 5 are rotatably connected. Rotating the screw can adjust the deformation of the elastic sealing component 2 to adjust the shape and volume of the cleaning chamber 9.

[0030] The shape of the limiting component 4 matches the screwing tool or the limiting component 4 is provided with anti-slip grooves, so as to facilitate the use of tools or manual rotation of the lead screw.

[0031] The elastic sealing component 2 is preferably made of rubber.

[0032] Wherein, valves are provided on both the inlet pipe 6 and the sewage pipe 7.

[0033] To sum up, when using this camshaft rear bearing cover cleaning device, the cleaning part 8 is placed in the cleaning chamber 9, the driving component 3 is moved to deform the elastic sealing component 2, so that the cleaning chamber 9 formed by the elastic sealing component 2 is adapted to the cleaning part 8, and the volume of the cleaning space is reduced. Then, the cleaning medium is injected into the cleaning chamber 9 through the inlet pipe 6 to clean the cleaning part 8, thereby reducing the waste of the cleaning medium, increasing the flow rate of the cleaning medium, and improving the flushing effect of the cleaning medium. Finally, the dirt is discharged from the drain pipe 7.
