It completes the sealing of fuel gas together with the cylinder, piston, cylinder wall, etc. The early piston ring was formed by casting, but with the progress of technology, high-power steel piston rings were born. When the opening milling machine tool of the prior art opens the piston ring, the piston ring is clamped by a clamp, and the rotation of the piston ring is realized by the oil cylinder. The oil cylinder is difficult to ensure the machining precision and cannot well control the pushing progress. In addition, different specifications of the piston ring need to be opened with different sizes, and a solution needs to be proposed to solve the above technical problems.

[0003] As disclosed in the patent document CN216096590U, the device clamps and mills the opening through the left and right clamping head seats, the first nut seat of the first driving mechanism moves up and down to drive the swing plate and the left swing arm to swing, the left and right swing arms are connected by a connecting shaft to realize synchronous swinging, thereby driving the left and right clamping head seats to swing synchronously, and driving the piston ring to swing left and right. The position of the milled opening can be adjusted as needed, and openings of different sizes can be milled.

[0004] However, the existing device needs to manually load the piston ring into the tool clamp for outer corner processing when processing the end face and outer corner of the piston ring. After processing is completed, the piston ring is manually taken out of the clamp, which is low in efficiency, poor in safety, and cannot guarantee the quality, and cannot realize automatic processing. Secondly, the process of taking out the piston ring after processing by clamping the mold sleeve to fix the piston ring is easy to scratch the inner wall of the clamping mold sleeve, which reduces the efficiency of the clamping mold sleeve for clamping the piston ring. Finally, in the prior art, the piston ring is cooled and flushed with water during processing, and the piston ring is not dried during collection. The piston ring will rust if stored in a humid environment for a long time, which affects the product quality of the piston ring. SUMMARY
