The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1

[0025] Reference Figure 1 to Figure 5 , which is the first embodiment of the utility model, provides a piston ring cleaning device, which can realize the cleaning of the piston ring after honing, and the cleaning and loading and unloading are more convenient.

[0026] A piston ring cleaning device includes a cleaning machine 1 with a cleaning pool 102, a gear box 7 is fixedly connected to the upper side of the cleaning frame 101 of the cleaning machine 1, a transmission motor 6 is fixedly connected to the upper side of the gear box 7, the transmission motor 6 is connected to the input end of the gear box 7, a rotating connecting plate 2 is connected to the output shaft 5 of the gear box 7, a support portion 501 is fixed to the outer end of the output shaft 5, a positioning hole 203 is opened in the center of the rotating connecting plate 2, a plurality of connecting countersunk holes 502 are arranged on the output shaft 5 outside the support portion 501, and the positioning holes 203 are arranged outside the output shaft 5. The rotating connecting disk 2 is provided with a plurality of connecting holes 202 corresponding to the connecting countersunk holes 502. When the supporting portion 501 is inserted into the positioning hole 203, the connecting hole 202 can be coaxial with any connecting countersunk hole 502. The rotating connecting disk 2 is provided with a plurality of hanging units 3 for hanging piston rings. The hanging unit 3 includes a hanging rod 302. A detection port 201 is provided on the rotating connecting disk 2 close to the hanging rod 302. A photoelectric switch 4 is fixedly connected to the cleaning frame 101. The photoelectric switch 4 can be aligned with any detection port 201.

[0027] The hanging rod 302 above the cleaning machine 1 and close to the photoelectric switch 4 is the loading station. At this time, the photoelectric switch 4 is aligned with the detection port 201 on one side of the hanging rod 302, and the position of the hanging rod 302 above the cleaning machine 1 and away from the photoelectric switch 4 is the unloading station; in the initial state, the detection port 201 at the loading station is aligned with the photoelectric switch 4, and the photoelectric switch 4 detects whether there is an obstruction under the loading station. The external manipulator transfers the honed piston ring to the loading station, and the photoelectric switch 4 detects the presence of the piston ring, and the photoelectric switch 4 loads the piston ring. The material signal is transmitted to the external controller to control the operation of the transmission motor 6, and the output shaft 5 drives the rotating connecting disk 2 to rotate (with the main view as a reference, the rotating connecting disk 2 rotates counterclockwise), and the rotating connecting disk 2 drives the piston ring to rotate downward to the set position in the cleaning tank 102, and the transmission motor 6 stops moving, and the cleaning is completed. The transmission motor 6 continues to move, and when it rotates to the unloading station, the external manipulator removes the piston ring; it does not require people to fish out the piston ring in the cleaning tank 102, which is convenient for loading the piston ring before cleaning and unloading the piston ring after cleaning.

[0028] Specifically, one end of the hanging rod 302 away from the rotating connecting disk 2 is fixedly connected to a baffle 303 extending toward the center of the rotating connecting disk 2. When the hanging rod 302 is above the cleaning frame 101, the baffle 303 is downward relative to the hanging rod 302. When the hanging rod 302 is in the cleaning pool 102, the baffle 303 is upward relative to the hanging rod 302.

[0029] With this design, when the piston ring is driven into the cleaning tank 102, the piston ring will not slide into the cleaning tank 102 due to the blocking effect of the baffle 303, thereby further improving the reliability of cleaning and discharging.
