[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the flipping mechanism 3 consists of a second cylinder 301, a rack 302, a limit bar 303, a gear 304, a drive shaft 305, a drive pulley 306, a drive belt 307, a driven pulley 308, a connecting shaft 309, and an electric push rod 310. The second cylinder 301 is fixedly connected to the top of the base plate 2. The front end of the rack 302 is fixedly connected to the output end of the second cylinder 301. The gear 304 is located above the rack 302, and the gear 304 meshes with the rack 302. The drive shaft 305 is rotatably connected to both ends of the mounting bracket 1, and the drive shaft 305 is fixedly connected to the gear 304.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the limiting strip 303 is fixedly connected to the bottom surface of the rack 302, and a sliding groove adapted to the limiting strip 303 is provided on the top of the base plate 2.

[0026] By allowing the limit bar 303 to slide inside the groove, the rack 302 can be ensured to move in a straight line, thus improving the stability of the rack 302's movement.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that both ends of the drive shaft 305 extend outside the mounting bracket 1. The drive pulley 306 is symmetrically and fixedly connected to the outside of the end of the drive shaft 305. The drive belt 307 is located outside the drive pulley 306. The driven pulley 308 is located above the drive belt 307. The connecting shaft 309 is rotatably connected to the inside of the fixed base 5. One end of the connecting shaft 309 is fixedly connected to the driven pulley 308. The fixed end of the electric push rod 310 is fixedly connected to the other end of the connecting shaft 309.

[0028] As can be seen from the above working process, by using the set flipping mechanism 3, the control cylinder 2 301 can drive the connecting shafts 309 on the left and right sides to rotate synchronously, thereby driving the compressor fixed by the clamping mechanism 4 to flip, so that the processing equipment can quickly complete the processing of multiple sides of the compressor, greatly reducing the labor intensity of workers, saving time, and improving production efficiency.

[0029] Further as Figure 1 , Figure 3 and Figure 4As shown, it is worth noting that the clamping mechanism 4 consists of a fixed disk 401, a rotating disk 402, a connecting plate 403, a connecting disk 404, a fixed shaft 405, a rotating rod 406, a clamping block 407, a telescopic rod 408, a connecting block 409, a connecting column 410, and an electric push rod 411. The fixed disk 401 is fixedly connected to the output end of the electric push rod 310. The rotating disk 402 is rotatably connected to the inside of the fixed disk 401 on the side away from the electric push rod 310. The connecting plate 403 is symmetrically fixedly connected to one side of the rotating disk 402, and the connecting disk 404 is fixedly connected to the other side of the connecting plate 403.

[0030] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that there are three connecting plates 403 and three fixed shafts 405. The fixed shafts 405 are symmetrically fixedly connected to one side of the fixed plate 401. One end of the rotating rod 406 is rotatably connected to the outside of the fixed shaft 405. The clamping block 407 is rotatably connected to the other end of the rotating rod 406. The rotating rod 406 is located between the two connecting plates 403. The telescopic rod 408 is fixedly connected between the clamping block 407 and the connecting plate 403.

[0031] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting block 409 is fixedly connected to the lower outer side of the rotating disk 402, the connecting column 410 is rotatably connected to one side of the connecting block 409, the electric push rod 411 is fixedly connected to the lower side of the fixed disk 401, and the output end of the electric push rod 411 is rotatably connected to the connecting column 410.

[0032] When the connecting block 409 is running, the connecting column 410 drives the connecting block 409 to move, thereby driving the rotating disk 402 to rotate inside the fixed disk 401, improving the practicality of the mechanism.

[0033] This solution has the following working process: In use, the workpiece is first placed above the support plate 7. The cylinder 6 is controlled to move the support plate 7 upwards until the horizontal axis of the workpiece above the support plate 7 is at the same height as the clamping mechanism 4. Then, the electric push rod 310 is controlled to move the two fixed plates 401 towards each other until both ends of the workpiece are respectively positioned inside the rotating disk 402. Next, the electric push rod 411 is controlled to move the connecting block 409, thereby causing the rotating disk 402 to rotate. The telescopic rod 408 drives the clamping block 407 to rotate, and the rotating rod 406 controls the distance between the clamping blocks 407 until the arc-shaped surface of the clamping block 407 contacts the workpiece. After clamping and fixing the workpiece, the first cylinder 6 drives the support plate 7 to reset to avoid affecting the workpiece's flipping. Then, the workpiece can be processed. When it is necessary to process the other side of the workpiece, the second cylinder 301 drives the rack 302 to move, which drives the transmission shaft 305 to rotate through the gear 304. The drive pulley 306 and the transmission belt 307 drive the upper connecting shaft 309 to rotate. The electric push rod 310 can drive the clamping mechanism 4 and the workpiece to rotate and flip. By controlling the extension length of the rack 302, the rotation angle of the gear 304 can be adjusted, thereby controlling the workpiece's flipping angle and improving the flexibility of the fixture.

[0034] In summary: By using the flipping mechanism 3, the control cylinder 2 301 can drive the connecting shafts 309 on both sides to rotate synchronously, causing the compressor fixed by the clamping mechanism 4 to flip. This allows the processing equipment to quickly complete the processing of multiple sides of the compressor, greatly reducing the labor intensity of workers, saving time, and improving production efficiency. Through the clamping mechanism 4, cylinder 6, and support plate 7, the relative distance of the clamping mechanism 4 and the clamping size of the clamping block 407 can be adjusted to adapt to the processing needs of air conditioning compressor parts of different shapes and sizes, thereby improving the applicability and flexibility of the fixture.
