[0036] A worm 802 is rotatably connected to one side of the inner wall of the mounting box 8, a threaded sleeve 805 is sleeved on the shaft of the threaded rod 804, the worm 802 is meshed with the worm wheel 803, a connecting plate 11 is provided at the rear end of the threaded sleeve 805, an electric telescopic rod 14 is provided on the inner wall of the movable plate 12, and the other side of the output end of the electric telescopic rod 14 is fixedly connected to the outer wall of the lifting box 7;

[0037] The meshing transmission between the worm 802 and the worm wheel 803 is self-locking, which can ensure the stability of the position of the cutting knife 15 after it is adjusted to the appropriate height, and prevent height changes due to external factors such as vibration. The threaded sleeve 805 and the connecting plate 11 convert rotational motion into linear motion to achieve precise lifting and lowering of the cutting knife 15. The connection between the electric telescopic rod 14 and the lifting box 7 further enhances the flexibility and controllability of the height adjustment of the cutting knife 15.

[0038] The two sides of the rear end of the lifting box 7 are provided with slide grooves 17, and the front end of the connecting plate 11 slides with the inner wall of the connecting groove 18. The two sides of the front end of the connecting plate 11 are slidably connected with the inner wall of the slide groove 17. The slide groove 17 provides a precise guide for the up and down movement of the connecting plate 11, ensuring that the cutting knife 15 will not deviate during the lifting process, further improving the accuracy and stability of the position of the cutting knife 15. This sliding connection method can reduce the influence of vibration or other external force factors on the position of the cutting knife 15 during the cutting process, ensuring that the cutting knife 15 always moves along the predetermined trajectory, which is beneficial to improving the quality and accuracy of gear processing. A protective glass 2 is hingedly connected to one side of the body box 1, and a PLC control panel 4 is fixedly connected to the rear end of the main body box 1. The hinged protective glass 2 is convenient for the operator to open for installation and removal of gears. At the same time, closing it when the equipment is running can effectively prevent debris generated during the cutting process from splashing and injuring people, protecting the safety of the operator. The PLC control panel 4 provides a convenient control interface for the automated operation of the entire equipment. The operator can accurately set and adjust the cutting parameters, motor speed, etc. on the panel to achieve precise control of the equipment, improve production efficiency and product quality, and also facilitate fault diagnosis and maintenance of the equipment.

[0039] A third servo motor 801 is fixedly connected to one side of the front end of the inner wall of the mounting box 8, and the output end of the third servo motor 801 is fixedly connected to the front end of the worm 802.

[0040] The rear end of the upper surface of the base plate 5 is fixedly connected to a fixing frame 6, the middle part of the lower end of the fixing frame 6 is fixedly connected to a first servo motor 13, the upper end of the fixing frame 6 is rotatably connected to a placement plate 9, the middle part of the upper surface of the placement plate 9 is fixedly connected to a clamping column 10, and the first servo motor 13 provides stable and precise power for the rotation of the placement plate 9. The clamping column 10 can firmly fix the gear to ensure that the gear will not be displaced during the cutting process. During cutting, the first servo motor 13 drives the placement plate 9 and the gear to rotate at a constant speed. Combined with the precise position control of the cutting knife 15, it can achieve uniform cutting in the circumferential direction of the gear, ensure the consistent processing accuracy of each tooth or other cutting part, improve the quality and performance of the gear, and is also suitable for processing gears of various shapes and sizes.

[0041] A second servo motor 16 is fixedly connected to the middle of the other side of the connecting plate 11, and a cutting knife 15 is rotatably connected to the middle of the connecting plate 11. The high-speed rotating cutting knife 15 cooperates with the uniformly rotating gear to achieve efficient and precise cutting, reduce burrs, cracks and other defects in the cutting process, and improve the surface quality and dimensional accuracy of gear processing. The output end of the second servo motor 16 passes through the connecting plate 11 to the outside of the connecting plate 11 and is fixedly connected to the outer wall of the cutting knife 15. The second servo motor 16 serves as the power source for the rotation of the cutting knife 15 and can accurately control the rotation speed of the cutting knife 15. The rotation speed of the cutting knife 15 can be flexibly adjusted through the PLC control panel 4 according to factors such as gear material and thickness to ensure the stability of the cutting process and the cutting quality.

[0042] Working principle: This gear processing and cutting equipment realizes the opening and closing of the operating area through the hinged protective glass 2. After opening the protective glass 2, the gear to be processed is placed on the placement plate 9 so that the middle part of the gear is engaged with the clamping column 10, thereby fixing the gear. This fixing method provides a basis for subsequent stable cutting and ensures that the gear will not be displaced during the cutting process. After closing the protective glass 2, the equipment forms a relatively closed working space, which not only protects the safety of the operator but also reduces the interference of external factors on the cutting process. The PLC control panel starts the electric telescopic rod 14, and the electric telescopic rod 14 pushes the lifting box 7 to slide on the bottom plate 5 to realize the preliminary coarse adjustment of the cutting knife 15 in the vertical direction. At the same time, the third servo motor 801 in the mounting box 8 is started, driving the worm 802 to rotate, and the worm wheel 803 engaged with the worm 802 rotates accordingly. Since the worm wheel 803 is fixedly connected to the threaded rod 804, the threaded rod 804 also rotates, and the threaded sleeve 805 on the threaded rod 804 rotates. Under the action of the drive mechanism, the drive mechanism 11 drives the cutting knife 15 to be further accurately adjusted in the vertical direction through the connecting plate 11. This method of the electric telescopic rod 14 and the threaded transmission mechanism working together can control the distance between the cutting knife 15 and the gear, ensuring that the cutting knife 15 is close to the gear at the optimal height, and preparing for accurate cutting. After the height of the cutting knife 15 is adjusted into place, the first servo motor 13 is started, driving the placement plate 9 and the clamping column 10 to rotate, thereby making the gear fixed on the clamping column 10 rotate at a uniform speed. At the same time, the second servo motor 16 installed on the connecting plate 11 drives the cutting knife 15 to rotate at a high speed. During the rotation of the gear, the cutting knife 15 cuts the gear. Since the height of the cutting knife 15 is accurately adjusted and the gear rotates at a uniform speed, the cutting knife 15 can achieve uniform cutting in the circumferential direction of the gear. Whether it is cutting the tooth shape of the gear or other parts that need to be processed, the consistency of each cutting position can be guaranteed, thereby effectively improving the processing quality of the gear.
