Description

Technical Field

[0001] This utility model relates to the field of rotor cutting technology, specifically to a cutting mechanism for an automatic de-weighting and balancing machine for motor rotors. Background Technology

[0002] The cutting mechanism of an automatic rotor balancing machine is designed to improve the motor's stability and lifespan by balancing the rotor and eliminating unbalanced mass. As the core component of the balancing machine, the cutting mechanism is responsible for removing material from the unbalanced parts of the rotor.

[0003] According to a public announcement (Publication No.: CN 212443542 U), a motor rotor cutting and repair device includes a cutting mechanism, a vertical lifting mechanism, and a moving slide mechanism. The vertical lifting mechanism is located at the upper end of the moving slide mechanism, and the cutting mechanism is installed in front of the vertical lifting mechanism. The cutting mechanism includes a brushless DC motor, a hexagonal support column, a baffle, a support frame, a front locking nut, a spindle seat, a spindle, and a cutter. The drive end of the brushless DC motor is connected to the spindle through a second coupling.

[0004] The aforementioned method, which relies on the interaction between components such as hexagonal supports and baffles, is insufficient to ensure the rotor's stability during the cutting process with flexibility and precision. This leads to changes in the rotor's position, resulting in uneven or inaccurate cutting and reduced adaptability, which requires improvement. Utility Model Content

[0007] Two fixing plates and threaded sleeves are provided and are symmetrical to each other along the vertical central axis of the bidirectional lead screw. The two fixing plates help to clamp the two sides of the rotor to be cut and prevent displacement.

[0008] The fixing plate is located on the inner wall of the machine body, at the bottom of the rotor and cutting tool. This design ensures that the movement of the fixing plate is not affected, allowing for normal operation and movement.

[0009] Two supports are provided and are symmetrical to each other along the vertical central axis of the machine body. A touch screen is provided on the side of the machine body. The design of the touch screen is conducive to direct operation, control and adjustment of parameters of the machine body.

[0013] A spring is fixedly connected to the inner wall of the rectangular box. The end of the spring away from the rectangular box is fixedly connected to the bottom of the displacement plate. The design of the spring is conducive to the automatic reset of the displacement plate when it is not compressed.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-5 As shown, this embodiment proposes a cutting mechanism for an automatic rotor balancing machine for motors, including a machine body 1. A control panel 2 is provided on the side of the machine body 1. A cutting anti-movement component 3 is provided on the inner wall of the machine body 1. The cutting anti-movement component 3 includes a bracket 31. The bottom of the bracket 31 is fixedly connected to the top of the machine body 1. A motor 36 is provided on the side of the bracket 31. A rotating rod 32 is provided on the output shaft of the motor 36. A rotor 33 is provided on the circumferential surface of the rotating rod 32. A cutting tool 34 is provided on the inner wall of the machine body 1. A support rod 35 is fixedly connected to the side of the machine body 1. A motor 37 is fixedly connected to the side of the support rod 35. A bidirectional lead screw 38 is fixedly connected to the output shaft of the motor 37. A threaded sleeve 39 is threadedly connected to the circumferential surface of the bidirectional lead screw 38. A cylindrical rod 310 is fixedly connected to the side of the motor 37. The end of the cylindrical rod 310 away from the motor 37 passes through the side of the threaded sleeve 39. A fixing plate 311 is fixedly connected to the side of the threaded sleeve 39.

[0028] There are two fixing plates 311 and threaded sleeves 39, which are symmetrical to each other along the vertical central axis of the double-acting screw 38. The two fixing plates 311 help to clamp the two sides of the rotor 33 to be cut and prevent displacement.

[0029] The fixing plate 311 is located on the inner wall of the machine body 1, at the bottom of the rotor 33 and the cutting tool 34. This design helps to ensure that the movement of the fixing plate 311 is not affected, allowing it to move normally.

[0030] There are two brackets 31, which are symmetrical to each other along the vertical central axis of the body 1. A touch screen 312 is provided on the side of the body 1. The design of the touch screen 312 is conducive to direct operation, control and adjustment of parameters of the body 1.

[0031] In this embodiment, motor 36 drives the rotating rod 32 to rotate, and the rotation of the rotating rod 32 drives the rotor 33 to rotate. Therefore, the rotor 33 is an electric rotor 33. The unbalanced rotor 33 is cut by the cutting tool 34. Motor 37 is started and rotated forward. The forward rotation of motor 37 drives the bidirectional lead screw 38 to rotate forward. The forward rotation of the bidirectional lead screw 38 will drive the two threaded sleeves 39 to move relative to each other. The relative movement of the two threaded sleeves 39 will drive the two fixed plates 311 to move relative to each other. The threaded sleeves 39 are limited by the cylindrical rod 310, so that the threaded sleeves 39 can only move laterally left and right, thereby driving the two fixed plates 311 to move laterally left and right. Located on both sides of the rotor 33, when the two fixing plates 311 move relative to each other, they will temporarily clamp the two sides of the rotor 33, temporarily limiting the rotor 33 so that the rotor 33 will not move during cutting. The bidirectional lead screw 38 drives the movement of the threaded sleeve 39 and the fixing plate 311, which can achieve precise limiting of the rotor 33. Compared with traditional fixing methods, such as simple mechanical clamps, this design is more flexible and precise, which can ensure the stability of the rotor 33 during the cutting process and avoid uneven or inaccurate cutting due to changes in the position of the rotor 33. This design has strong adaptability and can handle the clamping and limiting of rotors 33 of different sizes and shapes.

[0032] Example 2

[0033] like Figures 1-5 As shown, based on the same concept as in Embodiment 1 above, an automatic cooling and overheat protection component 4 is provided on the inner wall of the machine body 1. The automatic cooling and overheat protection component 4 includes a long rod 41, one end of which is fixedly connected to the top of the threaded sleeve 39. A pressing block 42 is fixedly connected to the side of the long rod 41. A rectangular box 43 is fixedly connected to the inner wall of the machine body 1. A liquid outlet pipe 48 passes through the side of the rectangular box 43. A square plate 44 is fixedly connected to the inner wall of the rectangular box 43. A displacement plate 45 is slidably connected to the inner wall of the rectangular box 43. A moving rod 46 is fixedly connected to the top of the displacement plate 45. A triangular block 47 is fixedly connected to the end of the moving rod 46 away from the displacement plate 45. A storage box 410 is fixedly connected to the inner wall of the machine body 1. A connecting pipe 49 passes through the top of the storage box 410. The end of the connecting pipe 49 away from the storage box 410 passes through the top of the rectangular box 43. The motor 36 is cooled by coolant to prevent overheating.

[0034] Two square plates 44 are provided and are symmetrical to each other along the vertical central axis of the displacement plate 45. The end of the liquid outlet pipe 48 away from the rectangular box 43 is located at the top of the motor 36. This design is conducive to allowing the coolant to flow directly onto the motor 36 for direct heat dissipation.

[0035] The triangular block 47 is located on the displacement trajectory of the extrusion block 42. A one-way valve 411 is provided at the top of the connecting pipe 49. A limit rod 412 is fixedly connected to the inner wall of the rectangular box 43. The end of the limit rod 412 away from the rectangular box 43 passes through the bottom of the displacement plate 45. The design of the limit rod 412 is beneficial to restrict the movement trajectory of the displacement plate 45 and prevent the movement trajectory of the displacement plate 45 from deviating.

[0036] A spring 413 is fixedly connected to the inner wall of the rectangular box 43. The end of the spring 413 away from the rectangular box 43 is fixedly connected to the bottom of the displacement plate 45. The design of the spring 413 is conducive to the automatic reset of the displacement plate 45 when it is not compressed.

[0037] In this embodiment, the threaded sleeve 39 moves bidirectionally, which moves the long rod 41 and the pressing block 42. The triangular block 47 and the moving rod 46 are located on the movement trajectory of the pressing block 42. When the pressing block 42 presses against the triangular block 47, it will press the triangular block 47 and the moving rod 46 downward. The storage box 410 contains coolant. When the one-way valve 411 is opened, the coolant is transferred to the rectangular box 43 through the connecting pipe 49. The connecting pipe 49 is located above the two square plates 44 and one displacement plate 45. Therefore, the coolant transferred in is located at the top of the two square plates 44 and one displacement plate 45, while the outlet pipe 48 is located below the two square plates 44 and one displacement plate 45. Therefore, the coolant temporarily transferred into the rectangular box 43 cannot flow out. When the moving rod 46 moves downward, it will slide between the two square plates 44, causing the two square plates to... A notch is created in the middle of plate 44, allowing coolant at the top of the two square plates 44 and the displacement plate 45 to flow downwards to the bottom of the two square plates 44 and the displacement plate 45. A drain pipe 48 runs through the bottom, allowing coolant to flow out. The end of the drain pipe 48 away from the rectangular box 43 is located next to the motor 36, allowing coolant to reach the motor 36 and dissipate heat from the rotor 33. The heat generated during cutting may increase friction between the cutting tool and the workpiece, affecting cutting accuracy and efficiency. Coolant not only helps dissipate heat but also reduces friction during cutting, improves cutting effect, and increases machining accuracy and cutting speed. Through effective heat dissipation, the coolant system can reduce overheating of the motor rotor 33 and other mechanical components, reduce wear and aging rates, extend equipment life, and reduce maintenance costs.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
