Description

Technical Field

[0001] The utility model relates to the technical field of mechanical basic parts and manufacturing, in particular to a spraying device for the inner wall coating of a bimetallic cylinder liner. Background Technique

[0002] An internal combustion engine cylinder liner includes a cylinder liner provided with an intake pipe and an exhaust pipe. A cylinder piston connected to a crankshaft connecting rod is arranged inside the cylinder liner. An inorganic non-metallic silicon nitride ceramic coating is arranged on the inner surface of the cylinder liner. The provided inorganic non-metallic silicon nitride ceramic coating not only improves the wear resistance, corrosion resistance and high temperature resistance of the cylinder liner, but also has high hardness and good thermal shock resistance. After the production and processing of the cylinder liner are completed, a spraying treatment needs to be carried out on the surface of the cylinder liner to extend its service life.

[0003] At present, the existing cylinder liner spraying device can fix and rotate the cylinder liner during spraying, which improves the spraying uniformity to a certain extent.

[0004] For example, a cylinder liner spraying device disclosed in the authorized publication number CN218945409U, belonging to the technical field of cylinder liners, includes a bottom support plate, a lifting frame installed on the top of the bottom support plate, and a sleeve column installed on the top of the bottom support plate. A spraying liquid tank is installed on the top of the bottom support plate. A liquid guide pipe is connected to the bottom of one side of the spraying liquid tank. Two lifting motors are installed on the top of the lifting frame. The output shaft of each lifting motor is coaxially connected with a threaded rod. A lifting block is sleeved on the two threaded rods. A clamping block inserted into a rotating seat is installed at the bottom of the sleeve column. Three top blocks are installed on the inner wall of the sleeve column. Two springs are connected to each top block. Each top block is connected to a top plate through two springs. The sleeve column is slidably inserted with a top column through the three top blocks. However, for such a cylinder liner spraying device, when the spraying pipe sprays paint on the bimetallic cylinder liner, the generated spray will pollute the surrounding environment, and it is not convenient to check the paint spraying amount in real time and add it in time.
