Description

Technical Field

[0001] This utility model relates to the technical field of piston ring cleaning equipment, specifically an automatic piston ring cleaning equipment for receiving materials. Background Technology

[0002] Piston rings undergo multiple processes during production, which may generate impurities and oil stains. If these are not removed promptly, they will affect the sealing performance and durability of the piston rings. Cleaning ensures the cleanliness of the piston ring surface and prevents impurities from affecting engine performance.

[0003] Existing piston ring cleaning equipment cannot achieve a reasonable connection with the previous process. It generally needs to be transferred through a transfer station, which increases costs and reduces production efficiency. For example, a piston ring cleaning mechanism disclosed in CN 106269643 A requires the setting of a piston ring picking chamber and a picking robot, which is complex in structure and high in cost.

[0026] 2) The second lifting drive motor 22 drives the second lead screw 21 to rotate, which drives the receiving pipe 29 to the lowering position. The first rotation drive motor 26 drives the receiving pipe 29 to rotate to the docking state with the receiving and cleaning rack 4.

[0027] 3) The linear driver 30 pushes the piston ring 50 on the receiving pipe 29 onto the receiving and cleaning rack 4, and then the first rotary drive motor 26 drives the receiving pipe 29 to rotate to the right to the lowering position.

[0028] 4) The second rotary drive motor 38 drives the rotating shaft 37 to rotate, and the rotating shaft 37 drives the piston ring to rotate, so that the opening of the piston ring passes through the rotating shaft 37 and falls down onto the piston ring support track 34. At the same time, the top spray head 42 connects to spray water to rinse the piston ring.

[0029] 5) The first lifting drive motor 43 drives the first lead screw 14 to rotate, which drives the piston ring connected to the receiving and cleaning rack 4 at the lower end of the L-shaped bracket 13 into the cleaning tank 1 for cleaning. After cleaning, the piston ring is pushed to output along the T-shaped discharge track 44 (the piston ring can be pushed manually or by a drive structure to output, but the specific structure is not within the scope of protection of this application).
