Description

Technical Field

[0001] This application relates to the technical field of engine cylinder head manufacturing and processing, and in particular to a special cleaning machine for engine cylinder heads. Background Technology

[0002] During the manufacturing and processing of engine cylinder heads, residual metal shavings, oil stains, and coolant may remain. Before installation, the engine cylinder head needs to be cleaned to ensure the surface and mating surfaces are clean. This guarantees good sealing and assembly quality, preventing air and oil leaks. Furthermore, a clean surface facilitates subsequent quality inspection, ensuring product consistency and reliability—a crucial step in guaranteeing engine performance and safe operation.

[0003] In related technologies, the cleaning process of engine cylinder heads is mostly carried out manually, combined with compressed air and chain-plate through-type spray cleaning equipment. After cleaning, the cylinder heads are dried with compressed air.

[0004] Regarding the aforementioned technologies, manual operation makes it difficult to standardize and control the degree of cleanliness, which can easily lead to incomplete or over-cleaning of products. Secondly, the overall cleaning efficiency is low, affecting the production cycle and failing to meet the needs of modern, efficient production lines. Summary of the Invention

[0047] The implementation principle of a dedicated engine cylinder head cleaning machine according to this application embodiment is as follows: The operator controls the piston rod of the opening cylinder 12 to retract, causing the cover 11 to rotate and open. The rotation drive device drives the fixed base 4 to be horizontally positioned. The piston rods of the two position adjustment cylinders 6 retract, causing the two height clamping components 5 to move in opposite directions, placing the workpiece 100 to be cleaned between multiple positioning blocks 44. The multiple positioning blocks 44 will position the workpiece 100 to be cleaned in the horizontal direction. The piston rod of the position adjustment cylinder 6 is extended, causing the two clamping blocks 54 to move above the workpiece 100 to be cleaned. The piston rods of the two height drive cylinders 58 retract, causing the two clamping blocks 54 to press firmly onto the workpiece 100 to be cleaned. The operator controls the piston rod of the opening cylinder 12 to extend, causing the cover 11 to close. The water pump 13 is turned on, drawing the heated cleaning solution from the water tank 7 into the bag filter 14. After filtration, the solution is sprayed out from the spray nozzles of multiple spray columns 31 through the spray pipe. Simultaneously, the rotary drive device drives the fixed base 4 to rotate around the axis of the rotating shaft 41, achieving all-round cleaning of the workpiece 100. After cleaning, the air pump blows air onto the workpiece 100 through the air jet pipe to dry it. The operator then controls the piston rod of the cover-opening cylinder 12 to retract, controlling the rotary drive device to drive the fixed base 4 to a horizontal position, with the workpiece 100 above the fixed base 4. The piston rods of the two-position adjustment cylinder 6 retract, while the piston rods of the height drive cylinder 58 extend, allowing the operator to remove the workpiece 100 from the fixed base 4.

[0048] While the water jet 31 is spraying water to clean the workpiece 100, the wastewater will flow back to the water storage tank 7 through the open opening of the drainage trough 21. The oil removal device 9 and the slag removal device 8 in the water storage tank 7 will maintain the cleanliness of the cleaning solution in the water storage tank 7, so as to achieve recycling.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
