Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a dynamic balancing and weight-reducing cutting device. Background Technology

[0002] Currently, in rotor motors, the dynamic balance of the rotor plays a crucial role. Due to various factors such as uneven material, defects in the blank, errors in processing and assembly, and even asymmetrical geometry in the design, the centrifugal inertial forces generated by each tiny particle on the rotor cannot cancel each other out when it rotates. The centrifugal inertial forces act on the machine and its foundation through the bearings, causing vibration, generating noise, accelerating bearing wear, shortening the life of the machine, and in severe cases, causing destructive accidents.

[0003] For related technology, please refer to Chinese patent application CN218592630U, which discloses a dynamic balancing and weight-reducing device, including a base, a first cylinder facing downward on the base, a stepper motor connected to the rod end of the first cylinder, a clamping coupling on the shaft of the stepper motor, a clamp below the clamping coupling, a workpiece fixed in the clamp, the base of the workpiece connected to the clamp, the rotating part of the workpiece being opposite to the clamping coupling, a second cylinder on one side of the clamp, and an electric grinding head connected to the rod end of the second cylinder.

[0004] Regarding the aforementioned technologies, when the deweighting device removes weight from the workpiece, the electric grinding head grinds the workpiece. During this grinding process, the resulting debris falls into the cabinet and fixture. When the workpiece is finished being ground, the operator needs to clean the debris from the cabinet and fixture. This process takes a lot of time and the debris cleaning is inconvenient. Utility Model Content

[0005] To improve the ease of debris removal, this application provides a dynamic balancing and weight-removing cutting device.

[0006] This application provides a dynamic balancing and weight-removing cutting device, which adopts the following technical solution:

[0007] A dynamic balancing and weight-reducing cutting device includes a cutting device body, which comprises a cabinet, a lifting component, a gripper mechanism, a fixing component, and a grinding component. The lifting component is located inside the cabinet, and the gripper mechanism is located below the lifting component. The lifting component is used to drive the gripper mechanism to move vertically. A support plate is fixed inside the cabinet, and the support plate is arranged along the length of the cabinet and located below the gripper mechanism. A support block is fixed at the upper end of the support plate, and the support block is arranged along the length of the support plate. An arc-shaped groove is formed at the upper end of the support block along the length direction. A receiving opening connected to the arc-shaped groove is formed vertically on the support block. The grinding component is located in the receiving opening and is used to grind the rotor. A pressing component is provided on one side of the support block along the width direction, and the pressing component is used to position the rotor. The fixing component is located above the support plate and is used to fix the rotor.

[0008] By adopting the above technical solution, the cutting device body is used to grind the motor rotor. During operation, the motor rotor is located inside the cabinet. The lifting component drives the gripper mechanism to grab the rotor. Then, the gripper mechanism rotates and moves to directly above the support block. The support plate supports the support block. The gripper mechanism places the rotor in the arc groove on the support block. The fixing component fixes the rotor. The grinding component in the collection port grinds the rotor. The grinding debris passes through the arc groove and falls into the collection port, which helps to reduce the probability of debris splashing into the cabinet and improves the convenience of debris cleaning.

[0009] Optionally, the lifting component includes a first horizontal plate, a second horizontal plate, and two first cylinders. The first horizontal plate is fixedly connected to the upper end of the cabinet, the two first cylinders are fixedly connected to the lower end of the first horizontal plate and are arranged vertically, the upper end of the second horizontal plate is fixedly connected to the output end of the two first cylinders, and the gripper mechanism is connected to the second horizontal plate.

[0010] By adopting the above technical solution, the first horizontal plate supports the first cylinder. When the gripper mechanism needs to grasp the rotor, the two first cylinders extend, and the first cylinders and the second horizontal plate work together to drive the gripping mechanism to move downward, which improves the convenience of the gripper mechanism's movement.

[0011] Optionally, the gripper mechanism includes a rotary motor, a connecting plate, and two gripper components. The rotary motor is fixedly connected to the upper end of the second horizontal plate and located between the two first cylinders. The output shaft of the rotary motor passes through the second horizontal plate and is fixedly connected to the center of the connecting plate. The two gripper components are respectively fixedly connected to both sides of the connecting plate along its length.

[0012] By adopting the above technical solution, the connecting plate supports the two gripper pieces. When one of the gripper pieces grabs the rotor, the lifting component drives the connecting plate to move upward. At this time, the rotating motor drives the connecting plate to rotate, so that the rotor is located directly above the support block. Then, the lifting component drives the connecting plate to descend, and the gripper piece places the rotor in the arc groove on the support block. At the same time, the other gripper piece grabs other rotors, which improves the efficiency of rotor grabbing and placement.

[0013] Optionally, the fixing components include a positioning block, a moving block, a moving component, a drive motor, two connecting cylinders, and a rubber sleeve. The positioning block is vertically fixed to the upper end of the support plate and located on one side of the support block along its length. One of the connecting cylinders passes through the positioning block and is detachably connected to it. The moving block is located on the side of the support block away from the positioning block and is slidably connected to the support plate along its length. The moving component is located at the upper end of the support plate and is used to drive the moving block to move along the length of the support plate. The drive motor is fixedly connected to the upper end of the moving block. The other connecting cylinder is coaxially fixedly connected to the output shaft of the drive motor. The rubber sleeve is fixedly connected inside the connecting cylinder near the drive motor and is arranged along the length of the connecting cylinder. The inner diameter of the rubber sleeve is smaller than the diameter of the rotor on both sides.

[0014] By adopting the above technical solution, the positioning block supports one of the connecting cylinders. When the rotor is placed in the arc-shaped groove, the positional relationship between the connecting cylinder and the positioning block is adjusted so that one end of the rotor is located inside the connecting cylinder. At this time, the moving part and the moving block cooperate to drive the drive motor to move closer to the support block, thereby making the other end of the rotor located inside the other connecting cylinder. The moving block continues to move, and at this time, one end of the rotor is located inside the rubber sleeve. Since the inner diameter of the rubber sleeve is smaller than the diameter of the rotor, the rubber sleeve and the rotor are in a tight fit. When the rotor needs to be rotated, the drive motor rotates, and the connecting cylinder and the rubber sleeve cooperate to drive the rotor to rotate, which improves the convenience of rotor fixing and rotor rotation.

[0015] Optionally, the pressing component includes an inclined block, a second cylinder, a connecting block, a rotating block, a micro motor, and a pressing block. The inclined block is fixedly connected to the upper end of the support plate and located on one side of the support block along the width direction. The upper surface of the inclined block is inclined from bottom to top along the direction from the inclined block to the support block. The second cylinder is fixedly connected to the upper end of the inclined block and located on the side of the inclined block away from the support block. The connecting block is slidably connected to the upper end of the inclined block along the length direction and fixedly connected to the output end of the second cylinder. The rotating block is rotatably connected to the side of the connecting block away from the second cylinder. The micro motor is fixedly connected to one side of the connecting block along the width direction. The output shaft of the micro motor passes through the connecting block and is fixedly connected to the rotating block. The pressing block is fixedly connected to the side of the rotating block away from the connecting block.

[0016] By adopting the above technical solution, when the connecting cylinder is fixed to the rotor, the second cylinder pushes the connecting block along the inclined block toward the support block. When the pressure block is above the rotor, the micro motor rotates to drive the rotating block to rotate, thereby making the pressure block fit with the rotor and fixing the rotor, thus improving the stability of the rotor during grinding.

[0017] Optionally, the grinding components include a milling cutter, a rotating component, and a telescopic component. The telescopic component is located inside the receiving opening and is fixedly connected to the upper end of the support plate. The rotating component is connected to the telescopic component and is used to drive the rotating component to move up and down vertically. The milling cutter is located on the side of the rotating component away from the telescopic component and is used to drive the milling cutter to rotate. The milling cutter is directly opposite the arc-shaped groove.

[0018] By adopting the above technical solution, the rotating component drives the milling cutter to rotate. At this time, the telescopic component drives the rotating component and the milling cutter to rise vertically, so that the milling cutter contacts the rotor and grinds the rotor. The grinding debris falls into the collection port, which improves the convenience of rotor grinding and the convenience of debris cleaning.

[0019] Optionally, the support plate has a vertically opening for a discharge port that is connected to the storage opening, and a storage box is provided at the lower end of the support plate. The storage box is directly opposite the discharge port and is detachably installed with the support plate.

[0020] By adopting the above technical solution, the grinding debris passes through the collection port and discharge port in sequence and is stored in the collection box, which further improves the convenience of debris cleaning.

[0021] Optionally, a controller is fixed to the upper part of the cabinet.

[0022] By adopting the above technical solution, the controller is used to set the milling cutter speed and lifting height, which improves the convenience of grinding parameter adjustment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During operation, the lifting component drives the gripper mechanism to grab the rotor. The gripper mechanism rotates and moves above the support block, placing the rotor in the arc-shaped groove. The fixing component and the pressing component work together to fix the rotor. The grinding component grinds the rotor. The grinding debris passes through the collection port and the discharge port in sequence and falls into the collection box, improving the convenience of debris cleaning.

[0025] 2. When the fixing component fixes the rotor, one end of the rotor is located inside the rubber sleeve. Since the inner diameter of the rubber sleeve is smaller than the diameter of one end of the rotor, the rubber sleeve and the rotor are in a tight fit. When the rotor needs to be rotated, the drive motor rotates, and the connecting cylinder and the rubber sleeve cooperate to drive the rotor to rotate, which improves the convenience of rotor rotation.

[0026] 3. After one of the grippers grabs the rotor, the lifting component moves the connecting plate upward. At this time, the rotating motor drives the connecting plate to rotate, so that the rotor is directly above the support block. Then, the lifting component moves the connecting plate downward, and the gripper places the rotor in the arc groove on the support block. At the same time, the other gripper grabs other rotors, which improves the efficiency of rotor grabbing and placement. Attached Figure Description

The lifting component 2 is located inside the cabinet 11, and the gripper mechanism 3 is located below the lifting component 2. The lifting component 2 is used to drive the gripper mechanism 3 to move vertically up and down.

[0034] Reference Figure 1The lifting component 2 includes a first horizontal plate 21, a second horizontal plate 22, and two first cylinders 23. The first horizontal plate 21 is fixedly connected to the upper end of the cabinet 11, and the two first cylinders 23 are fixedly connected to the lower end of the first horizontal plate 21 and are arranged vertically. The first horizontal plate 21 supports the two first cylinders 23. The upper end of the second horizontal plate 22 is fixedly connected to the output end of the two first cylinders 23. The gripper mechanism 3 is connected to the second horizontal plate 22. When the two first cylinders 23 extend simultaneously, they drive the second horizontal plate 22 to move downward, thereby driving the gripper mechanism 3 to move downward.

The support plate 12 is arranged along the length of the cabinet 11 and is located below the gripper mechanism 3. A support block 13 is fixed at the upper end of the support plate 12. The support block 13 is arranged along the length of the support plate 12 and supports the support block 13. An arc-shaped groove 14 is formed at the upper end of the support block 13 along the length. When the rotor is ground, the rotor is located in the arc-shaped groove 14.

[0036] Reference Figure 1 The gripper mechanism 3 includes a rotary motor 31, a connecting plate 32, and two gripper pieces 33. The rotary motor 31 is fixedly connected to the upper end of the two horizontal plates and located between the two first cylinders 23. The output shaft of the rotary motor 31 passes through the second horizontal plate 22 and is fixedly connected to the center of the connecting plate 32. The rotary motor 31 rotates, causing the connecting plate 32 to rotate. The two gripper pieces 33 are respectively fixedly connected to both sides of the connecting plate 32 along the length direction. The connecting plate 32 supports the two gripper pieces 33. When one of the gripper pieces 33 grips the rotor, the lifting member 2 drives the connecting plate 32 to move upward. At this time, the rotary motor 31 drives the connecting plate 32 to rotate, thereby placing the rotor directly above the support block 13. At this time, the lifting member 2 drives the connecting plate 32 to descend, and the gripper piece 33 places the rotor in the arc groove 14 on the support block 13. At the same time, the other gripper piece 33 grips other rotors, improving the efficiency of rotor gripping and placement.

[0037] Reference Figure 2 The fixing member 4 is located above the support plate 12 and is used to fix the rotor. The fixing member 4 includes a positioning block 41, a moving block 42, a moving part 43, a drive motor 44, and two connecting cylinders 45. The positioning block 41 is fixedly connected to the upper end of the support plate 12 vertically and is located on one side of the support block 13 along the length direction. One of the connecting cylinders 45 passes through the positioning block 41 and is detachably set with the positioning block 41. The positioning block 41 supports one of the connecting cylinders 45. When the rotor is placed in the arc groove 14, the positional relationship between the connecting cylinder 45 and the positioning block 41 is adjusted so that one end of the rotor is located in the connecting cylinder 45.

[0038] Reference Figure 2 The movable block 42 is located on the side of the support block 13 away from the positioning block 41, and is slidably connected to the support plate 12 along its length.

The drive motor 44 is fixedly connected to the upper end of the movable block 42, and another connecting cylinder 45 is coaxially fixedly connected to the output shaft of the drive motor 44. The movable component 43 and the movable block 42 cooperate to drive the drive motor 44 to move closer to the support block 13, thereby making the other end of the rotor located inside the other connecting cylinder 45.

[0039] Reference Figure 2 A pressing member 5 is provided on one side of the support block 13 along the width direction. The pressing member 5 is used to position the rotor. The pressing member 5 includes an inclined block 51, a second cylinder 52, a connecting block 53, a rotating block 54, a micro motor 55, and a pressing block 56. The inclined block 51 is fixedly connected to the upper end of the support plate 12 and is located on one side of the support block 13 along the width direction. The upper end surface of the inclined block 51 is inclined from bottom to top along the direction from the inclined block 51 to the support block 13. The support plate 12 supports the inclined block 51. The second cylinder 52 is fixedly connected to the upper end of the inclined block 51 and is located on the side of the inclined block 51 away from the support block 13. The connecting block 53 is slidably connected to the upper end of the inclined block 51 along the length direction of the inclined block 51 and is fixedly connected to the output end of the second cylinder 52. The extension of the second cylinder 52 drives the connecting block 53 to move on the upper end surface of the inclined block 51.

[0040] Reference Figure 2 The rotating block 54 is rotatably connected to the side of the connecting block 53 away from the second cylinder 52. The micro motor 55 is fixedly connected to the side of the connecting block 53 along the width direction. The output shaft of the micro motor 55 passes through the connecting block 53 and is fixedly connected to the rotating block 54. The pressure block 56 is fixedly connected to the side of the rotating block 54 away from the connecting block 53. When the pressure block 56 is above the rotor, the micro motor 55 rotates and drives the rotating block 54 to rotate, thereby making the pressure block 56 fit against the rotor and fixing the rotor, which improves the stability of the rotor during grinding.

[0041] Reference Figure 2 and Figure 3The support block 13 has a vertically opening 15 for receiving the rotor, which is connected to the arc-shaped groove 14. The grinding component 6 is located inside the receiving opening 15 and is used to grind the rotor. The grinding component 6 includes a milling cutter 61, a rotating component 62, and a telescopic component 63.

The milling cutter 61 is located on the side of the rotating component 62 away from the telescopic component 63. The milling cutter 61 is directly opposite the arc-shaped groove 14. The rotating component 62 drives the milling cutter 61 to rotate. At this time, the telescopic component 63 drives the rotating component 62 and the milling cutter 61 to rise vertically, so that the milling cutter 61 contacts the rotor and grinds the rotor. The grinding debris falls into the receiving opening 15.

[0042] Reference Figure 3 The fixing component 4 also includes a rubber sleeve 46, which is fixedly connected to the inside of the connecting cylinder 45 near the drive motor 44 and is set along the length of the connecting cylinder 45. The inner diameter of the rubber sleeve 46 is smaller than the diameter of the two sides of the rotor. When the connecting cylinder 45 fixes the rotor, both ends of the rotor are located inside the connecting cylinder 45. The moving block 42 continues to move, and at this time, one end of the rotor is located inside the rubber sleeve 46. Since the inner diameter of the rubber sleeve 46 is smaller than the diameter of the rotor, the rubber sleeve 46 is in a tight fit with the rotor. When the rotor needs to be rotated, the drive motor 44 rotates, and the connecting cylinder 45 and the rubber sleeve 46 cooperate to drive the rotor to rotate, thereby adjusting the position of the rotor so that the milling cutter 61 can grind other parts of the rotor.

[0043] Reference Figure 1 and Figure 3 The support plate 12 has a vertically opened discharge port 16 that is connected to the storage port 15. The lower end of the support plate 12 is provided with a storage box 17. The storage box 17 is directly opposite to the discharge port 16 and is detachably set with the support plate 12. The grinding debris passes through the storage port 15 and the discharge port 16 in sequence and is stored in the storage box 17, which further improves the convenience of debris cleaning.

[0044] Reference Figure 1 A controller 18 is fixedly installed at the upper end of the cabinet 11. The controller 18 is used to set the rotation speed and lifting height of the milling cutter 61, which improves the convenience of adjusting the grinding parameters.

[0045] The implementation principle of the dynamic balancing and weight-removing cutting device in this application embodiment is as follows: During operation, the first cylinder 23 extends, and the first cylinder 23 cooperates with the second horizontal plate 22 to drive the gripper 33 to descend. The gripper 33 grips the rotor. When the gripping is completed, the first cylinder 23 and the second horizontal plate 22 cooperate to drive the gripper 33 to rise. At this time, the rotating motor 31 drives the connecting plate 32 to rotate, thereby placing the rotor directly above the support block 13. The gripper 33 places the rotor into the arc groove 14. The fixing member 4 fixes the rotor. The telescopic member 63 drives the rotating member 62 and the milling cutter 61 to lift. The rotating member 62 drives the milling cutter 61 to rotate, thereby grinding the rotor surface. The grinding debris passes through the collection port 15 and the discharge port 16 in sequence and falls into the collection box 17, which helps to reduce the probability of debris remaining on the cabinet 11 and the support plate 12 and improves the convenience of debris cleaning.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
