Description

Technical Field

[0001] This utility model relates to the technical field of compressor end cover processing equipment, and in particular to a clamping device for processing automotive air conditioning compressor end covers. Background Technology

[0002] The automotive air conditioning compressor is the heart of the automotive air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement. Based on their working principles, air conditioning compressors can be classified as fixed displacement compressors and variable displacement compressors. During the compressor manufacturing process, the end cap needs to be connected to the compressor, and this process requires clamping the compressor end cap.

[0003] A search revealed a public disclosure (announcement) number: CN217914775U, which discloses a processing device for the rear cover of an automotive air conditioning compressor. The device includes a support plate and a chuck. The support plate is slidably fitted with a base, and the base engages with the chuck. The chuck engages with a limit rod, and the limit rod is slidably fitted with a shaft. A lower pressure plate is provided at the upper end of the shaft. Several first grooves and spiral grooves are formed on the outer wall of the shaft. The first grooves are perpendicular to the upper end face of the chuck, and the spiral grooves communicate with the first grooves. The chuck is equipped with a slider that slidably engages with the first grooves. The limit rod is fixedly connected to the support rod via an elastic element. This invention uses a chuck controlled by a motor rotation to clamp the workpiece. Furthermore, a rotatable lower pressure block, controlled by the squeezing force generated by the chuck clamping the workpiece, presses down and limits the edge of the workpiece, thus ensuring that the internal processing of the workpiece is not affected. This effectively reduces processing steps and improves work efficiency.

[0004] While the above solution does not affect the internal processing of the workpiece and effectively reduces the processing steps, it is not convenient enough when moving the end cap and is not stable enough when clamping the end cap, making it difficult to clamp multiple end caps of different sizes at the same time to speed up work efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a clamping device for processing end caps of automotive air conditioning compressors. By setting up a moving unit, it solves the problem of inconvenience when moving the end cap. By setting up a clamping unit, it solves the problem of instability when clamping the end cap and the difficulty in clamping multiple end caps of different sizes at the same time to speed up work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Preferably, the clamping assembly in the clamping unit further includes a plurality of arc-shaped plates arranged in pairs at the bottom end of the corresponding movable slot, an extension block fixedly connected to the top of one of the arc-shaped plates, and snap-fit ​​grooves opened on both sides of the extension block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] I. In this utility model, by setting up a moving unit, starting the electric telescopic rod can drive the cylinder and telescopic column to move, thereby driving multiple end caps at the bottom of the telescopic column to move together. Furthermore, the cylinder can be started to drive the telescopic column to extend and retract up and down, driving multiple end caps to move in the vertical direction. Then, the rotating motor can be started to drive the connecting plate and multiple end caps to rotate, thereby fine-tuning the position of the end caps, facilitating connection with the compressor, and improving the convenience of moving the end caps.

[0020] II. In this utility model, by setting up a clamping unit, rotating multiple screw sleeves changes the distance between the corresponding two limiting plates, thereby changing the distance between the two arc-shaped plates to accommodate end caps of different sizes. At the same time, under the action of the second elastic column and the second spring, multiple push plates are moved to clamp end caps of different sizes. Furthermore, under the action of the first elastic column and the first spring, the snap-fit ​​plate snaps into the corresponding snap-fit ​​groove, simultaneously clamping multiple end caps of different sizes. This facilitates the connection of different end caps with their corresponding compressors, improving work efficiency. Attached Figure Description
