Description
Technical Field
[0001] This invention relates to the field of compressors, specifically a compressor valve plate machining production line. Background Technology
[0002] The compressor valve plate is a core component of the compressor, and its machining accuracy directly affects the overall performance and service life of the compressor. Traditional valve plate machining is mostly carried out by individual machines in a decentralized manner. The process involves manual feeding, positioning, flipping, transfer and inspection to complete the processes such as chamfering of air holes and surface polishing. The machining process relies on manual operation and experience judgment, making it difficult to form a continuous and automated production line.
[0003] Existing processing methods suffer from problems such as low positioning accuracy, easy bumping during flipping, and poor processing consistency. Manual transfer is inefficient and easily causes scratches on the valve plate surface. At the same time, the limit compatibility of valve plates of different specifications is poor, the chamfering and polishing positions are difficult to align precisely, and visual inspection and processing are disconnected, resulting in low production efficiency and high scrap rate, which cannot meet the needs of large-scale, high-precision valve plate processing.

The second plate 104 is provided with a second adjustable side limiting mechanism. The top of the second adjustable side limiting mechanism is provided with a second adjustable top limiting mechanism.
[0021] Those skilled in the art will understand that the valve plate is conveyed by the belt conveyor 1, the end is limited by the limit baffle 101, the valve plate is transferred to the first plate 103 on the stand 102 by the pick-and-place mechanism 3, the positioning detection is completed by the first vision sensor 107, the single-sided processing is completed by the first air hole chamfering mechanism 5 and the first polishing mechanism 6, and then the first push mechanism 9 sends it to the flipping mechanism 4 to flip it and enter the second plate 104 to complete the processing of the other side.

Both first sliding sleeves 205 are slidably connected to the first guide rod 204. A guide plate 206 is fixedly connected to the bottom of both first sliding sleeves 205. The left end of the guide plate 206 extends outward.
[0023] Those skilled in the art will understand that the guiding mechanism 2 drives the first double-headed threaded rod 202 to rotate via the first motor 203, causing the two first sliding sleeves 205 to move synchronously towards or away from each other along the first guide rod 204, thereby driving the two guide plates 206 to adjust their spacing.

Several slots 405 arranged in a ring array are opened on the outer circumferential surface of the rotating disks 404. The number of slots 405 is even. The slots 405 on the two rotating disks 404 are arranged in a one-to-one correspondence. Limiting rings 406 coaxially arranged with the rotating disks 404 are fixedly connected to the front and rear sides of the fourth mounting bracket 401.
[0027] As will be understood by those skilled in the art, the flipping mechanism 4 drives the rotating shaft 402 through the second motor 403 to rotate the two rotating disks 404.

[0040] The working principle and usage process of this device are as follows: The compressor valve plate is conveyed by the belt conveyor 1, automatically centered and guided by the guide mechanism 2, and after reaching the limit baffle 101, the pick-and-place mechanism 3 picks up the valve plate and transfers it to the first plate 103 through the vacuum suction hoist 307. The first adjustable side limit mechanism 7 and the first adjustable top limit mechanism 8 simultaneously complete the adaptive limit of the valve plate's side and top. The first vision sensor 107 performs positioning detection on the valve plate. Subsequently, the first air hole chamfering mechanism 5 completes the air hole chamfering process, and the first polishing mechanism 6 completes the surface polishing process. After completing the single-sided processing, the first push... The feeding mechanism 9 pushes the valve plate to the flipping mechanism 4. The flipping mechanism 4 drives the rotating disk 404 to rotate, so that the valve plate can be flipped 180°. The second pushing mechanism 10 pushes the flipped valve plate to the second plate 104. The positioning, chamfering and polishing of the other side of the valve plate are completed by the second adjustable side limiting mechanism, the second adjustable top limiting mechanism, the second vision sensor, the second air hole chamfering mechanism and the second polishing mechanism. The entire process of feeding, guiding, positioning, detection, chamfering, polishing, flipping, double-sided processing and process flow is completed automatically, so as to realize the efficient, high-precision and automated machining of the compressor valve plate.
