Description

Technical Field

[0001] The invention relates to the technical field of engine accessories, in particular to a chain cleaning machine. Background Art

[0002] The cleaning requirements for engine parts after processing are getting higher and higher. The cylinder head water jacket holes are very irregular and difficult to clean thoroughly. At present, the industry mostly uses fixed-point spraying for cleaning engine cylinder heads. The inner cavity of the engine cylinder head water jacket is relatively irregular, with concave, convex and curved inner holes. When cleaning by fixed-point spraying, the cleaning fluid cannot be sprayed into the inner cavity of the water jacket, resulting in incomplete cleaning of the inner cavity, affecting the overall cleanliness of the product, and the cleaning time is long. The traditional material conveyor belt will cause the spraying equipment to be unable to flush the inside of the water jacket from the bottom of the water jacket upward, and the water jacket needs to be turned over again for cleaning. This step is too cumbersome, and the cleaning fluid generated during the cleaning process is difficult to recover, and there will be residues on the conveyor belt. Therefore, a chain cleaning machine is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a chain cleaning machine for solving the problem of comprehensive cleaning of the water jacket in the prior art.

[0004] In order to achieve the above-mentioned purpose and other related purposes, the present invention provides the following technical solutions:

[0005] A chain cleaning machine comprises a base, a chain conveyor belt mounted in the base, a tooling seat mounted on the chain conveyor belt, and a spraying assembly arranged in the base for spraying the tooling seat;

[0006] A connecting rod is provided between the tooling seat and the chain conveyor. Two groups of connecting rods are provided in the tooling seat, and both groups of connecting rods penetrate the tooling seat. Two groups of connecting rod through holes are provided in the tooling seat, and the connecting rod through holes located at the front end of the chain conveyor in the forward direction are matched with the connecting rod clearance. A circumferentially arranged clamping seat is provided on the upper end surface of the tooling seat.

[0007] To implement the above technical solution, the water jacket to be cleaned is transported to the cleaning work surface by using a chain conveyor belt, and cleaned in cooperation with a spray assembly. The chain conveyor belt can reduce the obstruction of the traditional belt conveyor belt on the bottom surface to be cleaned of the workpiece, and the chain conveyor belt can reduce the occupancy of the cleaning surface at the bottom of the workpiece as much as possible, thereby achieving a better cleaning effect on the bottom of the workpiece, and the chain conveyor belt can reduce the residue of cleaning liquid on the conveyor belt during the cleaning process, thereby better recycling the cleaning liquid.

[0008] By passing both sets of connecting rods through the tooling seat and rotatably connecting the two sets of connecting rods to the tooling seat, the stability of the tooling seat moving with the chain conveyor can be ensured, and the connecting rod through-hole located at the front end of the chain conveyor in the forward direction is matched with the connecting rod clearance. At the turning point of the chain conveyor, the connecting rod has sufficient displacement space to ensure the reliability and stability of the movement of the connecting rod at the turning point of the chain conveyor. The upper end surface of the tooling seat is provided with a circumferentially arranged clamping seat to clamp the workpiece to be cleaned, thereby ensuring the stability of the workpiece during the cleaning process.

[0009] In one embodiment of the present invention, both ends of the connecting rod are respectively passed through the chain pins on the chain conveyor, and both ends of the connecting rod are rotatably connected to the chain.

[0010] To implement the above technical solution, both ends of the connecting rod are respectively passed through the chain pins on the chain conveyor, which can ensure the stability and reliability of the connecting rod moving with the chain on the chain conveyor.

[0011] In one embodiment of the present invention, the spray wheel assembly includes an upper spray head arranged above the chain conveyor and a lower spray head arranged below the lower end surface of the chain conveyor, and the upper spray head and the lower spray head spray the workpiece in the tooling seat on the chain conveyor.

[0012] To implement the above technical solution, the upper end and the lower end of the workpiece in the fixture seat are sprayed respectively by the upper spray head and the lower spray head, thereby ensuring comprehensive coverage of the spray and improving the cleaning effect.

[0013] In one embodiment of the present invention, a connecting pipe is provided between one side of the lower shower head and the upper shower head.

[0014] To implement the above technical solution, the setting of the connecting pipe can not only facilitate the connection between the upper spray head and the lower spray head, but also facilitate the transportation of the cleaning liquid, thereby ensuring the stability of the cleaning effect.

[0015] In one embodiment of the present invention, a chain pressure assembly is provided under the chain conveyor, and the chain pressure assembly includes an upper pressure frame and a lower pressure frame. The upper pressure frame is provided with two groups of upper pressure wheels, and the upper pressure wheels press the upper end of the chain of the chain conveyor. The lower pressure frame is symmetrically provided with two groups below the upper pressure frame, and both groups of lower pressure frames are provided with lower pressure wheel pairs to tighten the lower end of the chain of the chain conveyor.

[0016] To implement the above technical solution, in order to ensure the conveying stability of the chain conveyor during operation, an upper pressure frame and a lower pressure frame are arranged on the conveyor chain below the chain conveyor. Since the conveyor chain at the upper end has a workpiece that can press the chain, the chain will not shake. However, when the conveyor chain below the chain conveyor runs a long distance, if there is no compression treatment, the chain will jump and affect the stable operation of the equipment. The upper pressure wheel presses the upper end of the chain conveyor, and the two sets of lower pressure frames are provided with lower pressure wheels to tighten the lower end of the chain conveyor, thereby avoiding the conveyor chain below the chain conveyor from shaking during operation.

[0017] In one embodiment of the present invention, the holder is provided with a plurality of groups equally divided circumferentially on the upper end surface of the tooling seat, two groups of limiting protrusions are provided on the outer contour of the holder, a guiding slope is provided on the top of the limiting protrusion, and a limiting base is provided on the bottom of the limiting protrusion, and the holder is detachably connected to the tooling seat.

[0018] To implement the above technical solution, two sets of limiting protrusions are provided on the outer contour of the base, so that the workpiece to be cleaned can be placed on the workholding seat for positioning. The guiding slope on the top of the limiting protrusion can guide the workpiece to be placed on the workholding seat, and the limiting base at the bottom of the limiting protrusion can prevent the workpiece from being displaced after being placed, thereby ensuring the stability of the workpiece placed on the workholding seat.

[0019] As described above, a chain cleaning machine of the present invention has the following beneficial effects: by utilizing a chain conveyor belt to transport the water jacket to be cleaned to the cleaning working surface, and cooperating with a spray assembly for cleaning, the chain conveyor belt can reduce the obstruction of the traditional belt conveyor belt to the bottom surface to be cleaned of the workpiece, and the chain conveyor belt can reduce the occupancy of the cleaning surface at the bottom of the workpiece as much as possible, thereby achieving a better cleaning effect on the bottom of the workpiece, and the chain conveyor belt can reduce the residue of inclined liquid on the conveyor belt during the cleaning process, thereby better recycling the cleaning liquid.

[0020] By passing both sets of connecting rods through the tooling seat and rotatably connecting the two sets of connecting rods to the tooling seat, the stability of the tooling seat moving with the chain conveyor can be ensured, and the connecting rod through-hole located at the front end of the chain conveyor in the forward direction is matched with the connecting rod clearance. At the turning point of the chain conveyor, the connecting rod has sufficient displacement space to ensure the reliability and stability of the movement of the connecting rod at the turning point of the chain conveyor. The upper end surface of the tooling seat is provided with a circumferentially arranged clamping seat to clamp the workpiece to be cleaned, thereby ensuring the stability of the workpiece during the cleaning process.
