Description

Technical Field

[0001] The utility model relates to the technical field of engine parts processing, and more specifically to a shot blasting device for processing an engine piston ring. Background Art

[0002] The engine piston ring processing shot blasting device is a specific equipment used in the production and processing of engine piston rings. When in use, the engine piston ring is placed on the turntable of the turntable shot blasting machine, and the ring is ensured to be firmly placed and rotate smoothly with the turntable through appropriate clamping or positioning methods. After starting the equipment, the turntable rotates at a uniform speed according to the set speed. At the same time, multiple shot blasters distributed in different directions around the turntable (such as above, side, etc.) work synchronously. The projectiles in the shot blaster obtain sufficient kinetic energy under the action of high-speed rotating impellers and other components, and are ejected toward the piston ring on the turntable according to the angle set by the directional sleeve. As the turntable continues to rotate, the piston ring is repeatedly hit by projectiles from different directions, thereby achieving all-round and uniform shot blasting treatment of the ring, effectively removing surface oxide scale, impurities, etc., while enhancing the surface performance of the ring.

[0003] Under the existing technical conditions, there is a problem when the turntable shot blasting machine is working, that is, the surface where the engine piston ring fits the turntable is difficult to be polished during the conventional shot blasting process. In view of this, it is often necessary to turn the piston ring over and put it back on the turntable after completing one round of shot blasting to continue polishing the fitting surface. During the flipping operation, the turntable shot blasting machine can only be in a waiting state and cannot continue to carry out shot blasting operations. In this way, the effective working time of the equipment will be reduced accordingly, and the equipment utilization rate will be greatly reduced. For those automated production lines, this intermittent idle state of the equipment will break the continuity of production, and then have a negative impact on the overall production efficiency, making it difficult for the equipment to fully utilize its original production capacity advantages. Not only that, the flipping and grinding operation process will also slow down the processing efficiency of the engine piston ring, which is not conducive to the efficient completion of production tasks.

[0025] The rotating components 5 are arranged in a ring shape on the surface of the turntable 2, and every four rotating components 5 in the horizontal direction are connected to a driving component 4. The top of the outer surface of the left rotating roller 54 and the right rotating roller 59 is arc-shaped, and the top of the steel ball 510 extends to the upper surface of the base 51.

[0026] In this embodiment, by setting up a driving component 4 and a rotating component 5, after the engine piston ring is clamped by the left-turn roller 54 and the right-turn roller 59, the rotation of the turntable 2 can drive one of the left-turn rollers 54 to rotate, and the engine piston ring can be rotated.
