A fixed plate is fixedly mounted on one side of the bottom of the support plate, and a fixed clamp is installed at the bottom end of the fixed plate. A movable plate is movably connected to the other side of the bottom of the support plate, and a movable clamp corresponding to the fixed clamp is installed at the bottom end of the movable plate. A through groove is opened in the middle of the top of the support plate, and a movable connecting piece is movably connected inside the through groove. An adjusting screw is screwed inside the movable connecting piece, and a fixed nut is fixed at the top of the adjusting screw. A disassembly head is provided at the bottom end of the adjusting screw. A limiting groove is opened on one side of the through groove, and a lead screw is rotatably connected inside the limiting groove. The top end of the movable plate is screwed to the outside of the lead screw. One end of the limiting groove extends to the outer wall of the other side of the support plate, and a handwheel is fixed at one end of the limiting groove. In this solution, the fixed clamp and the movable clamp are fixed to the edge of the air conditioning compressor.

[0026] Embodiment one

[0027] This embodiment is the first embodiment of a repair fixture for automotive air conditioning compressors, such as... Figures 1 to 4 As shown, the device includes a fixed frame 1, a support 2, a screw 3, and a sleeve 4. The fixed frame 1 has a through hole 13 for the sleeve 4 to pass through. The support 2 is located on the top of the fixed frame 1. One end of the screw 3 is threaded to the support 2, and the other end of the screw 3 is connected to the sleeve 4. One end of the sleeve 4 has a sliding groove 41, and the other end of the sleeve 4 has an insertion groove 42 that cooperates with the fastening nut. The other end of the screw 3 has a sliding block 31, which can slide along the central axis of the sleeve 4 within the sliding groove 41. When the screw 3 rotates, it drives the sleeve 4 to rotate synchronously through the sliding block 31. The bottom of the fixed frame 1 has at least two fixing pins 5, which cooperate with the countersunk holes located on the drive plate.

[0028] The aforementioned repair tool for an automotive air conditioning compressor includes a mounting bracket 1, a support 2, a screw 3, and a sleeve 4. In use, the side of the mounting bracket 1 with the fixing pin 5 faces the drive disc, and the mounting bracket 1 is connected to the compressor housing. The drive disc of the compressor is rotated so that the countersunk holes on the drive disc align with the fixing pins 5 on the mounting bracket 1. The repair tool is pushed so that the fixing pins 5 are engaged in the countersunk holes. At this time, the drive disc is fixed, and the mounting bracket 1 and its support 2 are fixed to the compressor housing. The screw 3 is rotated; since one end of the screw 3 is threaded to the support 2, the screw 3 and support 2 slide relative to each other. Simultaneously, the rotation of the screw 3 drives the sleeve 4 to rotate via the sliding block 31, bringing the sleeve 4 close to the fastening nut on the compressor's drive disc. Pushing the sleeve 4 causes the sliding block 31 to slide relative to the sliding groove 41, allowing the insertion groove 42 of the sleeve 4 to engage with the fastening nut. Reversing the rotation of the screw 3 allows the sliding block 31 to drive the sleeve 4 to rotate in the opposite direction, completing the removal of the fastening nut. In this embodiment, the drive plate is fixed to the compressor housing by the fixing bracket 1 and the drive plate is limited by the fixing pin 5. The drive plate will not rotate during the process of disassembling the fastening nut, and the maintenance personnel can independently complete the disassembly of the fastening nut.

[0029] like Figure 3As shown, the spring is connected to the inner wall of the mounting groove at one end, and connected to the ball 32 at the other end. The sliding groove 41 is provided with a clamping hole, which cooperates with the ball 32. When the rotating screw 3 drives the sleeve 4 to rotate close to the fastening nut on the driving disc, the sleeve 4 is pushed, and the sleeve 4 moves relative to the sliding block 31, so that the sleeve 4 further approaches the driving disc. During the relative sliding of the sliding block 31 and the sliding groove 41, the inner wall of the sliding groove 41 extrudes the ball 32, and the spring is compressed. When the sliding block 31 slides to the position where the ball 32 corresponds to the clamping hole, the ball 32 is clamped into the clamping hole under the elastic force of the spring, limiting the sliding block 31, preventing the sliding block 31 from falling out of the sliding groove 41, and ensuring that the sleeve 4 can rotate synchronously while the rotating screw 3 rotates. It should be noted that other limiting structures that can limit the sliding block 31 and prevent the sliding block 31 from falling out of the sliding groove 41 are also applicable to this embodiment.

[0030] As shown in Figure 1 , Figure 2 , the fixing pin 5 is provided with three, which are uniformly spaced on the outer periphery of the through hole 13, and each of the three fixing pins 5 cooperates with one of the three counterbores on the driving disc. In implementation, the three fixing pins 5 are clamped into the three counterbores respectively, so that the driving disc is stably fixed and limited, preventing the driving disc from rotating with the fastening nut.

[0031] Specifically, as shown in Figure 1 , Figure 2 , the fixing pin 5 is cylindrical, and the bottom of the fixing pin 5 is provided with a first chamfer. In implementation, after the fixing frame 1 is connected to the shell of the compressor, the driving disc of the compressor is rotated so that the three counterbores on the driving disc are aligned with the three fixing pins 5, the maintenance tool is pushed, the fixing pin 5 is guided by the first chamfer, and the fixing pin 5 is further aligned with the counterbores and clamped into the counterbores.

[0032] The sliding block 31 is prismatic. Specifically, as shown in Figure 3 , the sliding block 31 can be cuboid, and the side surface of the sliding block 31 corresponds to the inner wall surface of the sliding groove 41 respectively, preventing the rotating screw 3 from rotating relative to the sliding groove 41, and ensuring that the sleeve 4 rotates synchronously while the rotating screw 3 rotates.

[0033] As shown in Figure 1 , Figure 2 , the support 2 is cylindrical, the bottom of the support 2 is fixedly connected to the top of the fixing frame 1, one end of the screw 3 is threadedly connected to the top of the support 2, and the side wall of the support 2 is provided with a plurality of operation windows 21. In implementation, when the rotating screw 3 drives the sleeve 4 to rotate close to the fastening nut on the driving disc, the maintenance personnel can apply force to the sleeve 4 through the operation window 21 to push the sleeve 4.

[0034] As shown in Figure 2 , the insertion groove 42 is hexagonal. The fastening nut is hexagonal, and the hexagonal insertion groove 42 can fit the fastening nut to unscrew the fastening nut when the sleeve 4 is reversed. It should be noted that the sleeve 4 can be selected according to the actual size of the fastening nut to match the insertion groove 42 at the bottom of the sleeve 4 with the corresponding fastening nut.
