AI Technical Summary
In the existing technology, the central shaft hole and working end face of the swash plate are unstable during machining due to the asymmetrical irregular structure of the slide plate, which makes it difficult to meet the accuracy requirements, resulting in unstable machining quality and a high scrap rate.
The universal tooling, consisting of a centering seat, Y-shaped limit block, U-shaped pressure plate and moving jaws, achieves precise positioning and stable clamping of the swashplate through the cooperation of positioning pins and inclined planes, adapting to the processing needs of different models of swashplates.
It improves the precision and stability of swashplate machining, reduces the scrap rate, enhances the versatility of tooling, and meets the needs of industrialized production.

A general tool for turning and drilling a swash plate of an automobile air conditioner compressor, characterized in that, include: The chuck consists of a base (1), a positioning base (2), a centering base (3), a Y-shaped limiting block (4), a moving jaw (5), a connecting block, and a U-shaped pressure plate (7). The base (1) is a single-jaw chuck for turning. A fixed positioning block (10) is provided on the side working end face. The moving jaw (5) is mounted on the working end face of the base (1) with a groove rail. It can move back and forth on the working end face within a radially limited range. A rotating shaft (8) is fixedly installed in the internal cavity. A shifting block (9) is rotatably fitted on the rotating shaft (8). Two shifting teeth (14) are correspondingly provided on the shifting block (9). The shifting teeth (14) correspond to the shifting groove structure opened on the moving jaw (5) and the pull rod (20) and are respectively fitted into the shifting groove. The positioning base (2) is radially corresponding to the moving jaw (5). It is fixedly mounted on the base by the fixed positioning block (10). On the end face of the chuck (1), the centering seat (3) and the Y-shaped limiting block (4) are fixedly installed on the positioning base (2) and are arranged in a corresponding manner. The upper end face of the centering seat (3) is an inclined plane, and a circular positioning groove coaxial with the base chuck (1) is opened in the central area. A positioning pin (11) is installed on the bottom surface of the circular positioning groove. The front end of the Y-shaped limiting block (4) extends radially towards the center of the base chuck (1) and branches symmetrically to both sides to form forks. The inner sides of the two forks have arc surfaces. The connecting block is fixedly installed on the right side of the moving jaw (5). The U-shaped pressure plate (7) is connected to the right side of the connecting block. The front end extends radially towards the center of the base chuck (1), and the inner side of the front end has a smooth transition surface with an inclination direction corresponding to the inclined plane of the upper end of the centering seat (3).
2. The general tooling for turning and drilling of the swash plate of an automobile air conditioner compressor according to claim 1, characterized in that: The centering seat (3) is connected to the positioning base (2) by a detachable bolt connection, and a cylindrical limiting pin (12) is provided between the centering seat (3) and the positioning base (2).
3. The general tooling for turning and drilling of the swash plate of an automobile air conditioner compressor according to claim 1, characterized in that: The positioning pin (11) is an elastic positioning pin equipped with a supporting spring (13).
4. The general tooling for turning and drilling of the swash plate of an automobile air conditioner compressor according to claim 1, characterized in that: The Y-shaped limiting block (4) is installed on the positioning base (2) by a detachable bolt connection. The bolt connection hole on the Y-shaped limiting block (4) is a strip hole arranged in the radial direction of the base chuck (1).
5. The general tooling for turning and drilling of the swash plate of an automobile air conditioner compressor according to claim 1, characterized in that: The U-shaped pressure plate (7) and the connecting block are connected by a split connection through a connecting column (15). The connecting column (15) is a cylindrical structure that fits inside the connecting block and is connected to the connecting block by a rear connecting bolt (17) set on the central axis of the connecting column (15). The U-shaped pressure plate (7) is connected to the connecting column (15) by a front connecting bolt (18) set coaxially with the rear connecting bolt (17), so that the U-shaped pressure plate (7) has a degree of rotational freedom relative to the connecting block.
6. The universal tooling for swashplate turning and drilling of an automotive air conditioning compressor as described in claim 5, characterized in that: A gasket (19) is provided between the rear connecting bolt (17) and the connecting column (15), and a separation gap distance ΔL is left between the gasket (19) and the connecting block.
