[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1-3As shown, a servo commutator precision machining device for easy maintenance includes a base 1, a control panel 2 mounted on the base 1, a movable groove 3 on the base 1, a first stepper motor 4 mounted on the side wall of the base 1 via a base, a first lead screw 5 mounted on the output shaft of the first stepper motor 4, the first lead screw 5 rotatably mounted on the inner wall of the movable groove 3, a movable block 6 assembled in the movable groove 3, a dust collection hopper 7 fixedly mounted on the movable block 6, a dust collection groove 7 having a dust collection hopper 7, multiple dust collection holes 8 on the dust collection hopper 7, a dust collection hose 9 mounted on the side wall of the dust collection hopper 7, a dust collection box 10 mounted at the other end of the dust collection hose 9, a dust collection container 11 placed inside the dust collection box 10, a handle 12 mounted on the outer wall of the dust collection container 11, a filter plate mounted on the side wall of the dust collection container 11, and an exhaust box 13 mounted on the side wall of the dust collection box 10, the two side walls of the exhaust box 13 and An exhaust trough 14 is provided on one side wall of the dust collection box 10. The exhaust trough 14 corresponds to the position of the filter plate. The first drive motor 15 is installed in the exhaust box 13 through the base. The rotor 16 is installed on the output shaft of the first drive motor 15. The fan blade 17 is installed on the rotor 16. During operation, the existing precision turning device has difficulty in efficiently collecting the debris generated during the precision turning of the servo commutator 25. The debris is easy to accumulate inside the device, making the device difficult to maintain and resulting in poor maintenance convenience. After the servo commutator 25 is clamped and fixed by two clamping blocks 24, the first stepper motor 4 is operated to drive the first lead screw 5 to rotate. The first lead screw 5 drives the moving block 6 to move horizontally. The moving block 6 drives the dust collection hopper 7 to move horizontally to the left, so that the dust collection hopper 7 moves to the periphery of the servo commutator 25.

[0020] Afterwards, the turning tool 32 performs precision machining on the surface of the servo commutator 25. During this process, debris is generated. The first drive motor 15 operates, driving the rotor 16 to rotate at high speed. The rotor 16 drives the fan blade 17 to rotate at high speed, causing the air inside the exhaust box 13, the dust collection box 10, the dust collection hose 9, and the dust collection hopper 7 to be instantly discharged from the exhaust channel 14. There is a pressure difference between the inside of the exhaust box 13, the dust collection box 10, the dust collection hose 9, and the dust collection hopper 7 and the outside. Under the action of the pressure difference, the debris and air are sucked into the dust collection hopper 7 together, and then enter the dust collection box 11 of the dust collection box 10 from the dust collection hose 9. The debris is intercepted by the filter plate on the side wall of the dust collection box 11, and the clean air is discharged from the exhaust channel 14. This achieves efficient collection of debris, avoids the accumulation of debris inside the device, avoids difficulties in device maintenance, and helps to improve the convenience of device maintenance.

[0021] Please see Figures 4-5As shown, a support seat 18 is mounted on the base 1. A second drive motor 19 is mounted on the support seat 18 via a base. A rotating seat 20 is mounted on the output shaft of the second drive motor 19. The rotating seat 20 is rotatably connected to the support seat 18. A sliding groove 21 is provided on the rotating seat 20. A second lead screw 22 is rotatably mounted on the inner wall of the sliding groove 21. The threads on the second lead screw 22 are symmetrically opposite. A knob is installed at one end of the second lead screw 22. Two sliders 23 are symmetrically assembled in the sliding groove 21. Clamping blocks 24 are mounted on the sliders 23. Servo commutators 25 are placed on the two clamping blocks 24. A first guide assembly is mounted on the base 1. The first guide assembly includes a first guide groove 26. A first guide groove 26 is provided on the base 1. A third stepper motor 27 is mounted on the side wall of the base 1 via a base. A third lead screw 28 is mounted on the output shaft of the third stepper motor 27. The third lead screw 28 is rotatably mounted on the support seat 1. A first guide block is installed on the inner wall of the first guide groove 26. A guide plate 29 is installed on the first guide block. A second guide assembly 30 is installed on the guide plate 29. The second guide assembly 30 has the same structure as the first guide assembly. A moving plate 31 is installed on the second guide block inside the second guide assembly 30. A turning tool 32 is installed on the moving plate 31. During operation, the existing precision turning device is difficult to perform efficient precision turning of the servo commutator 25 during the precision turning process, resulting in low precision turning efficiency. By placing the servo commutator 25 on two clamping blocks 24 and rotating the knob, the second lead screw 22 is driven to rotate. The second lead screw 22 drives the two sliders 23 on it to move synchronously in opposite directions. The two sliders 23 drive the two clamping blocks 24 to move synchronously in opposite directions. The two clamping blocks 24 clamp the inner wall of the servo commutator 25.

[0022] Then, the control system inside the control panel 2 controls the movement of the turning tool 32. Specifically, the third stepper motor 27 operates, driving the third lead screw 28 to rotate. The third lead screw 28 drives the first guide block to move horizontally left and right. The first guide block drives the guide plate 29 to move horizontally left and right. The guide plate 29 drives the moving plate 31 to move horizontally left and right. The moving plate 31 drives the turning tool 32 to move horizontally left and right, thus realizing the horizontal left and right movement of the turning tool 32. The second guide component 30 on the guide plate 29 operates in the same way as above, driving the moving plate 31 to move horizontally back and forth. The moving plate 31 drives the turning tool 32 to move horizontally back and forth, thus realizing the horizontal back and forth movement of the turning tool 32. In other words, the control system inside the control panel 2 controls the turning tool 32 to move accurately. At the same time, the second drive motor 19 operates, driving the rotating seat 20 to rotate. The rotating seat 20 drives the servo commutator 25 clamped on it to rotate. The turning tool 32 performs turning machining on the surface of the servo commutator 25, realizing efficient precision turning machining of the servo commutator 25, which is beneficial to improving the efficiency of precision turning machining.

[0023] Working principle: Existing precision turning devices struggle to efficiently collect debris generated during the precision turning of the servo commutator 25. This debris easily accumulates inside the device, making maintenance difficult and inconvenient. After clamping and fixing the servo commutator 25 with two clamping blocks 24, the first stepper motor 4 rotates the first lead screw 5. The first lead screw 5 drives the moving block 6 horizontally, which in turn moves the dust collection hopper 7 horizontally to the left, placing it around the periphery of the servo commutator 25. Then, the turning tool 32 performs precision turning on the surface of the servo commutator 25. During this process, debris is generated, which is then collected by the first drive motor 15, driving the rotor 16 to rotate at high speed. The rotor 16 drives the fan blades 17 to rotate at high speed, causing the air inside the exhaust box 13, dust collection box 10, dust collection hose 9, and dust collection hopper 7 to be instantly discharged from the exhaust channel 14. A pressure difference exists between the inside of the exhaust box 13, dust collection box 10, dust collection hose 9, and dust collection hopper 7 and the outside environment. Under the action of this pressure difference, debris and air are sucked into the dust collection hopper 7, and then enter the dust collection box 11 of the dust collection box 10 through the dust collection hose 9. The debris is intercepted by the filter plate on the side wall of the dust collection box 11, and clean air is discharged from the exhaust channel 14. This achieves efficient collection of debris, avoiding debris accumulation inside the device and preventing difficulties in device maintenance, thus improving the convenience of device maintenance. In the existing precision machining process of the servo commutator 25 surface... The servo commutator 25 is difficult to precision machine efficiently, resulting in low precision machining efficiency. To address this, the servo commutator 25 is placed on two clamping blocks 24. Rotating the knob drives the second lead screw 22 to rotate, which in turn drives two sliders 23 to move synchronously in opposite directions. These sliders, in turn, drive the two clamping blocks 24 to move synchronously in opposite directions, thus clamping the inner wall of the servo commutator 25. Then, the control system inside the control panel 2 controls the movement of the turning tool 32, which is achieved through the operation of the third stepper motor 27, driving the third lead screw 28 to rotate. The third lead screw 28 then drives the first guide block to move horizontally left and right, which in turn drives the guide plate 29 to move horizontally left and right, and the guide plate 29 then drives the moving plate 31 to move horizontally left and right. The moving plate 31 drives the turning tool 32 to move horizontally left and right, realizing the horizontal left and right movement of the turning tool 32; through the operation of the second guide component 30 on the guide plate 29, the same steps are performed, that is, the moving plate 31 is driven to move horizontally back and forth, and the moving plate 31 drives the turning tool 32 to move horizontally back and forth, realizing the horizontal back and forth movement of the turning tool 32; that is, the control system inside the control panel 2 controls the turning tool 32 to move accurately, and at the same time the second drive motor 19 operates, driving the rotating seat 20 to rotate, and the rotating seat 20 drives the servo commutator 25 clamped on it to rotate, and the turning tool 32 performs turning processing on the surface of the servo commutator 25, realizing efficient precision turning processing of the servo commutator 25, which is conducive to improving the efficiency of precision turning processing.
