[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a precision cutting device for valve body processing, the precision cutting device for valve body processing includes: a support frame 1, a servo motor 2 installed at one end of the support frame 1, a rotary motor 3 installed at the other end of the support frame 1, and a finger cylinder 4 installed at one end of the rotary motor 3.

[0025] Tool box 5, several precision cutting tools 6 are installed inside the tool box 5, and a moving slider 7 is installed below the tool box 5. The moving slider 7 is connected to a drive power supply 8.

[0026] In use, the valve body can be locked onto one end of the finger cylinder 4. The rotary motor 3 at one end of the finger cylinder 4 drives the finger cylinder 4 to rotate rapidly. At the same time, the servo motor 2 drives the tool box 5 to move longitudinally, and the drive power supply 8 drives the actuator slider 7 to slide laterally, thereby controlling the lateral movement of the tool box 5. The lateral and longitudinal movements of the tool box 5 work together to perform precision cutting on the valve body at one end of the finger cylinder 4. The tool box 5 can be equipped with multiple precision cutting tools 6, which can be switched at will, thus avoiding the problem of frequent tool changes.

[0027] Example 2: Based on Example 1, a lead screw 11 is provided to ensure the precision of the precision cutting process. A lead screw nut 12 is fitted on the surface of the lead screw 11. The end of the lead screw 11 closest to the motor housing 10 is fixedly connected to the inner ring surface of the fixed bearing 14. A fixed plate is provided at the other end of the lead screw 11. A hole is opened on the surface of the fixed plate, and a fixed bearing 14 is installed in the hole. The end of the lead screw 11 away from the motor housing 10 passes through the fixed bearing 14 in the fixed plate and is fixedly connected to the output end of the servo motor 2. The lead screw nut 12 has a "convex" shaped structure and is locked in the limiting slide frame 13. The lead screw nut 12 can be displaced within the limiting slide frame 13, which is fixedly installed on the surface of the support plate 9. During the precision cutting process, the servo motor 2 drives the lead screw 11 to rotate, causing the lead screw nut 12 on the surface of the lead screw 11 to move longitudinally. This allows the precision cutting tool 6 in the tool box 5 to be precisely displaced to the appropriate position in the longitudinal direction, ensuring the precision of the precision cutting process.

[0028] The moving slider 7 is installed inside the stator slide rail 21, allowing it to move within the stator slide rail 21. The moving slider 7 is electrically connected to the drive power supply 8, which is fixedly installed on the outer side of the support frame 1. Several holes are formed on the surface of the moving slider 7, and fixing screws are installed inside these holes. The external threads of the fixing screws are threaded into the mounting screw holes 19 on the lower surface of the tool box 5. The stator slide rail 21 is fixedly installed on the surface of the lead screw nut 12. A rotary motor 3 is installed inside the motor housing 10. A hole is formed on the surface of the motor housing 10 near the lead screw 11, and a rotary bearing 15 is fixedly installed inside this hole. The inner ring surface of the rotary bearing 15 is flush with the finger. The outer wall of the cylinder 4 is fixedly connected. The end of the finger cylinder 4 away from the lead screw 11 has a slot 16. A connecting shaft 17 is inserted into the slot 16. The connecting shaft 17 is fixedly connected to the output end of the rotary motor 3. During precision cutting, the rotary motor 3 in the motor housing 10 drives the valve body at one end of the finger cylinder 4 to rotate rapidly. At the same time, the drive power supply 8 drives the mover slider 7 to move laterally on the stator slide rail 21, thereby enabling the precision cutting tool 6 to move precisely laterally. Under the synergistic action of the lead screw nut 12 and the mover slider 7, the precision cutting tool 6 is controlled to move precisely longitudinally and laterally, thereby performing precision cutting on the rapidly rotating valve body.

[0029] Example 3: Based on Example 2, a tool box 5 is provided to avoid frequent tool replacements. The tool box 5 has a rectangular parallelepiped structure. A tool groove 18 is formed on the surface of the tool box 5 near the finger cylinder 4. A precision cutting tool 6 is inserted into the tool groove 18. Several mounting screw holes 19 are formed on both the upper and lower surfaces of the tool box 5. A mounting plate 20 is provided on the upper surface of the tool box 5. Several holes are formed on the surface of the mounting plate 20. Screws are placed in the holes and are threaded to the mounting screw holes 19 on the upper surface of the tool box 5. The support frame 1 has a rectangular parallelepiped structure. The structure includes a support plate 9 installed below, a motor housing 10 fixedly installed at one end of the support frame 1, a servo motor 2 fixedly installed at the other end of the support frame 1, and a lead screw 11 fixedly installed between the servo motor 2 and the motor housing 10. Before precision cutting, the required precision cutting tool 6 is installed in the tool slot 18 inside the tool box 5. Then, the precision cutting tool 6 is fixedly installed in the tool box 5 by the cooperation of the mounting plate 20 and the lead screw. Then, the precision cutting tool 6 for processing the valve body is adjusted by controlling the lateral and longitudinal movement of the precision cutting tool 6, thereby eliminating the need for frequent replacement of the precision cutting tool 6.

[0030] In actual use, the valve body can be locked onto one end of the finger cylinder 4. The rotary motor 3 at one end of the finger cylinder 4 drives the finger cylinder 4 to rotate rapidly. At the same time, the servo motor 2 drives the tool box 5 to move longitudinally, and the drive power supply 8 drives the mover slider 7 to slide laterally, thereby controlling the lateral movement of the tool box 5. The lateral and longitudinal movements of the tool box 5 work together to perform precision cutting on the valve body at one end of the finger cylinder 4. The tool box 5 can be equipped with multiple precision cutting tools 6, which can be switched at will, thus avoiding the problem of frequent tool changes.
