[0032] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: a valve sleeve milling fixture, including an installation shell 2, the installation shell 2 is used to install the entire clamping device. A motor 11 is fixedly connected inside the installation shell 2, and a rotating shaft 10 is fixedly connected to the driving end of the motor 11. Starting the motor 11 can drive the rotating shaft 10 to rotate. One end of the rotating shaft 10 is fixedly connected to a rotating plate 8, and the rotation of the rotating shaft 10 can drive the rotating plate 8 to rotate. A plurality of uniformly distributed connecting plates 12 are rotatably connected to one side of the rotating plate 8. When the rotating plate 8 rotates, it can drive the plurality of connecting plates 12 to rotate. One end of the connecting plate 12 away from the rotating plate 8 is rotatably connected to a moving block 7. When the connecting plate 12 rotates, it can drive the moving block 7 to slide. The outer circumference of the moving block 7 slides inside the installation shell 2. The moving block 7 is used to fix the clamping plate 5. One side of the moving block 7 is fixedly connected to the clamping plate 5. When the moving block 7 slides, it can drive the clamping plate 5 to move to clamp and fix the valve sleeve. The bottom of the installation shell 2 abuts against a base 1, and the base 1 is used to fix the installation shell 2.

[0033] Referring to Figure 1 , Figure 3 and Figure 4 , a disassembly component is provided between the installation shell 2 and the base 1. The disassembly component is used to disassemble the installation shell 2 for convenient maintenance or replacement. The disassembly component includes two connecting blocks 14. The two connecting blocks 14 are used to connect the base 1 and the installation shell 2. The top of the connecting block 14 is fixedly connected to the bottom of the installation shell 2. A support rod 13 is fixedly connected inside the base 1. The support rod 13 is used to support the slider 16 to make the slider 16 slide more stably. The outer circumference of the support rod 13 is slidably connected to a slider 16. The slider 16 is used to fix two convex blocks 15 and drive the two convex blocks 15 to move. Two convex blocks 15 are fixedly connected to the top of the slider 16. When the convex blocks 15 slide inside the connecting block 14, the installation shell 2 can be fixed. When the convex blocks 15 slide out of the inside of the connecting block 14, the fixation of the installation shell 2 is released. A sliding rod 4 is fixedly connected to one side of the slider 16. The sliding rod 4 is used to drive the slider 16 to slide. The outer circumference of the sliding rod 4 slides inside the base 1. A spring 17 is sleeved on the outer circumference of the support rod 13. One end of the spring 17 is fixedly connected to one side of the slider 16. Pressing the sliding rod 4 can drive the slider 16 to slide, so that the two convex blocks 15 slide out of the inside of the two connecting blocks 14 and compress the spring 17. Releasing the sliding rod 4 can make the spring 17 reset and drive the slider 16 to reset, so that the two convex blocks 15 slide into the inside of the two connecting blocks 14.

[0034] Referring to Figure 1 , Figure 3 and Figure 4, a fixing block 18 is fixedly connected to the outer periphery of the support rod 13. One end of the spring 17 away from the slider 16 is fixedly connected to one side of the fixing block 18. The fixing block 18 is used to fix the spring 17, which can prevent the spring 17 from shifting when compressed or restored. A plurality of uniformly distributed mounting holes 3 are provided inside the base 1. The plurality of mounting holes 3 are used to mount the base 1. A chute 9 is provided inside the front side of the mounting shell 2. The outer periphery of the clamping plate 5 is slidably connected inside the chute 9. When the moving block 7 slides, it can drive the clamping plate 5 to slide inside the chute 9 to clamp and fix the valve sleeve. A groove 19 is provided inside the connecting block 14. The outer periphery of the convex block 15 is slidably connected inside the groove 19. When the convex block 15 slides out of the groove 19, the fixing of the mounting shell 2 can be released, so as to repair or replace the mounting shell 2. One side of the clamping plate 5 is fixedly connected with an anti-slip pad 6. The anti-slip pad 6 is made of rubber. The anti-slip pad 6 is used to increase the friction between the clamping plate 5 and the valve sleeve, protect the surface of the valve sleeve, and prevent the valve sleeve from moving or vibrating during the processing. Two clamping grooves are provided inside the base 1. The outer periphery of the connecting block 14 is slidably connected in the clamping grooves provided inside a part of the base 1. The connecting block 14 slides into the base 1 through the clamping grooves.

[0035] Working principle: When the device needs to be used, the motor 11 needs to be started first to drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 can drive the rotating plate 8 to rotate. While the rotating plate 8 rotates, it drives a plurality of connecting plates 12 to rotate. While the plurality of connecting plates 12 rotate, they drive a plurality of moving blocks 7 to slide. The sliding of the plurality of moving blocks 7 drives a plurality of clamping plates 5 to move. The movement of the plurality of clamping plates 5 clamps and fixes the valve sleeve, thereby preventing the valve sleeve from displacing or vibrating during the processing. By pressing the sliding rod 4, the slider 16 can be driven to slide. While the slider 16 slides, it drives two convex blocks 15 to slide out of the two connecting blocks 14 and compresses the spring 17 at the same time, so as to release the fixing of the mounting shell 2 for repair or replacement. After the repair or replacement, the two connecting blocks 14 are slid into the base 1 again. At the same time, the sliding rod 4 is released to restore the spring 17. The restoration of the spring 17 drives the slider 16 to reset and makes the two convex blocks 15 slide into the two connecting blocks 14, thereby fixing the mounting shell 2.
