Description

Technical Field

[0001] This application relates to the field of motor manufacturing technology, and in particular to a motor rotor shaping device. Background Technology

[0002] The motor contains a stator and a rotor. The rotor contains a rotor core and an excitation winding. The rotor core has a columnar structure and is made of multiple layers of silicon steel sheets stacked together.

[0003] In related technologies, the motor rotor core is formed by stacking multiple silicon steel sheets or other magnetically conductive materials. During the stacking process, factors such as lamination precision errors, stacking process fluctuations, and external forces during transportation or assembly may cause deformation of the core, resulting in uneven end faces, radial dimensional deviations, local bulges, or depressions. To address these issues, a rotor core shaping process has emerged. The common method involves using specialized tools, such as shaping dies and presses, to correct and reshape the deformed core, restoring it to the designed geometric dimensions, shape accuracy, and surface quality. However, before the shaping operation, the rotor core needs to be loaded onto a testing table. Currently, this process is usually done manually; operators must manually place the rotor core on the testing table before proceeding with the subsequent shaping operation.

[0004] Regarding the aforementioned technologies, the existing manual feeding method has significant drawbacks. Manual feeding is inefficient, as operators must place each rotor core individually on the testing table, resulting in a slow feeding speed that cannot meet the demands of large-scale production. Furthermore, manual operation carries inherent risks; operators may be injured by equipment such as presses during the process, posing a safety hazard. Summary of the Invention

[0005] In order to provide an automated feeding and unloading shaping device, this application provides a motor rotor shaping device.

[0006] This application provides a motor rotor shaping device, which adopts the following technical solution:

[0007] A motor rotor shaping device, comprising

[0008] Workbench;

[0009] A conveyor belt is provided on the workbench for transporting a motor rotor. The transport direction of the conveyor belt is parallel to a first direction, and the top wall of the conveyor belt is flush with the top wall of the workbench.

[0010] The feeding assembly includes a feeding push rod, a positioning gripper, and a first driving member. The conveyor belt is disposed above the positioning gripper and the feeding push rod, and the positioning gripper and the feeding push rod are slidably connected to the worktable along a second direction, which is perpendicular to the first direction. The first driving member is used to drive the feeding push rod to slide.

[0011] A pressure plate is disposed between the positioning gripper and the feeding push rod. The pressure plate is slidably connected to the worktable along a third direction, which is perpendicular to both the first direction and the second direction.

[0012] The unloading assembly includes an unloading push rod and a second driving member. The unloading push rod is located between the positioning gripper and the conveyor belt. The unloading push rod is slidably connected to the worktable along a first direction. The second driving member is used to drive the unloading push rod to slide.

[0013] By adopting the above technical solution, and by setting up a feeding component and a discharging component, the conveyor belt transports the motor rotor along the first direction to between the feeding push rod and the positioning gripper. The first driving component drives the feeding push rod to slide along the second direction, and the positioning gripper and the feeding push rod clamp the rotor. The pressure plate slides along the third direction to contact the top wall of the rotor, thereby flattening the rotor. After the rotor is processed, the feeding push rod and the positioning gripper slide along the second direction to the side away from each other. The second driving component drives the discharging push rod to slide along the first direction, pushing the rotor to the side away from the feeding gripper. Through the first driving component, the second driving component, and the conveyor belt, the fully automatic feeding and discharging of the motor rotor can be achieved without manual operation, thus improving work efficiency.

[0014] Optionally, it may also include a third driving member for driving the pressure plate to slide in a third direction.

[0015] By adopting the above technical solution, and by setting a third driving component, the pressure plate is driven to slide along a third direction.

[0016] Optionally, a buffer assembly is also included, the buffer assembly comprising a first mounting base and an elastic element, the pressure plate being directly or indirectly fixedly connected to the bottom wall of the first mounting base, the third driving element being connected to the top wall of the first mounting base, the extension and retraction direction of the elastic element being parallel to a third direction, one end of the elastic element being fixedly connected to the worktable, and the other end being directly or indirectly connected to the first mounting base.

[0017] By adopting the above technical solution and setting a buffer component, when the pressure plate slides along the third direction, under the action of the elastic element, the pressure plate can receive the damping force of the elastic element when it moves downward along the third direction, thereby reducing the rigid impact between the rotor and the pressure plate.

[0018] Optionally, the buffer assembly further includes a first guide rod, which is a telescopic rod structure. The movable section of the first guide rod is fixedly connected to the bottom wall of the first mounting base, and the fixed section of the first guide rod is fixedly connected to the worktable. The ends of the fixed section and the movable section of the first guide rod that are close to each other are slidably connected in a third direction. The elastic element is sleeved on the fixed section of the first guide rod and is fixedly connected between the worktable and the movable section of the first guide rod.

[0019] By adopting the above technical solution, and by setting a first guide rod, which is a telescopic rod structure, when the pressure plate slides along a third direction, the movable section of the first guide rod slides along the fixed section, and the first guide rod guides the sliding of the pressure plate.

[0020] Optionally, the feeding assembly further includes a feeding slide, which is inclined and one end is fixedly connected to the worktable. The feeding slide is correspondingly arranged with the feeding push rod.

[0021] By adopting the above technical solution, by setting up a feeding slide, which is inclined, after the rotor is processed, the feeding push rod slides along the first direction to push the rotor to the feeding slide, and the rotor slides along the inclined direction of the feeding slide to the collection point.

[0022] Optionally, the positioning gripper includes a positioning plate and two arc-shaped plates connected to the positioning plate. The two arc-shaped plates have positioning areas in a first direction, and the arc-shaped openings of the two arc-shaped plates are arranged facing the positioning areas. The arc-shaped plates are movably connected to the positioning plate to change the width of the positioning areas.

[0023] By adopting the above technical solution, and by setting up arc-shaped plates, there is a positioning area between the two arc-shaped plates. The rotor is located in the positioning area, and the side wall of the rotor contacts the side wall of the arc-shaped plate. The contact area between the arc-shaped plate and the outer wall of the rotor is larger, thereby improving the stability of the rotor.

[0024] Optionally, the feeding push rod has a first arc-shaped groove extending through it in a third direction on the side near the arc-shaped plate.

[0025] By adopting the above technical solution, by setting a first arc-shaped groove on the feeding push rod, the rotor contacts the groove wall of the first arc-shaped groove, thereby improving the stability of the feeding push rod when it contacts the rotor.

[0026] Optionally, it also includes a first cleaning assembly, which includes a suction nozzle, an air duct, and a fan. A plurality of the suction nozzles are obliquely installed on the side wall of the pressure plate. One end of the air duct is connected to the suction nozzle, and the other end is connected to the fan. The fan is installed on the first mounting base.

[0027] By adopting the above technical solution and setting the first cleaning component, when the rotor is transported to the bottom of the pressure plate, the fan is started, and negative pressure is generated in the air duct. The negative pressure in the air duct and the external atmospheric pressure form a pressure difference, thereby sucking the debris into the air duct through the suction nozzle, reducing the debris residue on the rotor and improving product quality.

[0028] Optionally, a second cleaning component is also included. A second cleaning component is provided on both sides of the discharge slide. The second cleaning component is disposed on the discharge slide. The second cleaning component includes a cleaning plate and a magnetic strip. Magnetic strips are installed on both sides of the cleaning plate. The magnetic strips are parallel to the length direction of the discharge slide.

[0029] By adopting the above technical solution and setting a second cleaning component, the rotor passes through two feeding channels, and the magnetic strip can adsorb the iron filings adsorbed on the rotor, thereby improving the cleanliness of the rotor.

[0030] Optionally, the cleaning plate slides along the width direction of the discharge chute, and the cleaning plate contacts the bottom wall of the discharge chute.

[0031] By adopting the above technical solution, the cleaning plate is set to contact the bottom wall of the feeding slide. The cleaning plate slides along the width of the feeding slide and cleans the dust and debris on the feeding slide, thereby reducing dust contamination between the rotor and the feeding slide.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This application, by setting up a feeding component and a discharging component, transports the motor rotor along the first direction to between the feeding push rod and the positioning gripper. The first driving component drives the feeding push rod to slide along the second direction, and the positioning gripper and the feeding push rod clamp the rotor. The pressure plate slides along the third direction to contact the top wall of the rotor, thereby flattening the rotor. After the rotor is processed, the feeding push rod and the positioning gripper slide along the second direction to the side away from each other. The second driving component drives the discharging push rod to slide along the first direction, pushing the rotor to the side away from the feeding gripper. Through the first driving component, the second driving component, and the conveyor belt, the fully automatic feeding and discharging of the motor rotor can be realized without manual operation, thus improving work efficiency.

[0034] 2. This application sets up a first cleaning component. When the rotor is transported to the bottom of the pressure plate, the fan is started, and a negative pressure is generated in the air duct. The negative pressure in the air duct and the external atmospheric pressure form a pressure difference, thereby sucking the debris into the air duct through the suction nozzle, reducing the debris residue on the rotor and improving product quality.

[0035] 3. By setting a second cleaning component, the rotor passes through two feeding channels, and the magnetic strip can adsorb the iron filings adsorbed on the rotor, thereby improving the cleanliness of the rotor. Attached Figure Description

[0043] This application discloses a motor rotor shaping device. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically referred to in the figure, where the first direction is represented by X, the second direction by Y, and the third direction by Z. The first direction, the second direction, and the third direction are perpendicular to each other.

[0044] Reference Figure 1The motor rotor shaping device includes a worktable 1, a conveyor belt 2, a feeding assembly 3, and a pressure plate 4. The conveyor belt 2 is located on the worktable 1 and is used to transport the motor rotor. The transport direction of the conveyor belt 2 is parallel to the first direction. The feeding assembly 3 includes a feeding push rod 31, a positioning gripper 32, and a first driving member 33. The conveyor belt 2 is located between the positioning gripper 32 and the feeding push rod 31, and both the positioning gripper 32 and the feeding push rod 31 are slidably connected to the worktable 1 along the second direction. The first driving member 33 is used to drive the feeding push rod 31 to slide. The pressure plate 4 is located above the positioning gripper 32 and the feeding push rod 31. The pressure plate 4 is slidably connected to the worktable 1 along the third direction. The conveyor belt 2 transports the motor rotor along the first direction to the space between the feeding push rod 31 and the positioning gripper 32. The first driving member 33 drives the feeding push rod 31 to slide along the second direction. The positioning gripper 32 and the feeding push rod 31 clamp the rotor. The pressure plate 4 slides along the third direction until it contacts the top wall of the rotor, thereby flattening the rotor.

[0045] Reference Figure 1 In some embodiments, the first driving member 33 can be driven by a worm gear, a lead screw, or a cylinder. Any driving structure that can make the feeding push rod 31 slide is within the protection scope of this application. In this embodiment, the first driving member 33 is a cylinder. The cylinder housing is fixedly connected to the worktable 1, and the cylinder piston rod is parallel to the second direction and fixedly connected to the feeding push rod 31. The first driving member 33 drives the feeding push rod 31 to slide along the second direction.

[0046] Reference Figure 1 and Figure 2 In order to unload the processed rotor, the motor rotor shaping device also includes an unloading assembly 5. The unloading assembly 5 includes an unloading push rod 51 and a second driving member 52. The unloading push rod 51 is located between the positioning gripper 32 and the conveyor belt 2. The unloading push rod 51 is slidably connected to the worktable 1 along the first direction. The second driving member 52 is used to drive the unloading push rod 51 to slide. When the rotor is processed, the loading push rod 31 and the positioning gripper 32 slide away from each other along the second direction. The second driving member 52 drives the unloading push rod 51 to slide along the first direction, pushing the rotor away from the loading gripper.

[0047] Reference Figure 2 In some embodiments, the second driving member 52 can be a worm gear drive, a lead screw drive, or a cylinder drive. Any driving structure that can realize the sliding of the unloading push rod 51 is within the protection scope of this application. In this embodiment, the second driving member 52 is a cylinder. The cylinder housing is fixedly connected to the worktable 1, and the cylinder piston rod is parallel to the first direction and fixedly connected to the unloading push rod 51. The second driving member 52 drives the unloading push rod 51 to slide along the first direction.

[0048] Reference Figure 1 and Figure 2It should be noted that the conveyor belt 2 is existing technology in this field. The conveyor belt 2 slides along the first direction to transport multiple rotors. The driving structure of the conveyor belt 2 will not be described in detail here. The top wall of the conveyor belt 2 is flush with the top wall of the worktable 1.

[0049] Reference Figure 1 In order to facilitate the movement of the processed rotor to the collection point, the feeding assembly 5 also includes a feeding slide 53. The feeding slide 53 is inclined and one end of the feeding slide 53 is fixedly connected to the worktable 1. The feeding push rod 51 pushes the rotor to the feeding slide 53, and the rotor further slides from the inclined feeding slide 53 to the collection point (not shown in the figure).

[0050] Reference Figure 2 In order to drive the pressure plate 4 to slide in a third direction, the pressure plate 4 is driven by a third driving member 41. The third driving member 41 drives the pressure plate 4 to slide in a third direction. In this embodiment, the third driving member 41 is a cylinder.

[0051] Reference Figure 2 When the pressure plate 4 slides towards the rotor along the third direction, in order to reduce the rigid impact between the rotor and the pressure block, the motor rotor shaping device also includes a buffer assembly 6. In this embodiment, there are four buffer assemblies 6. The buffer assembly 6 includes a first mounting base 61 and an elastic element 62. The pressure plate 4 is fixedly connected to the bottom wall of the first mounting base 61 through the first connecting rod 42. The third driving element 41 is connected to the worktable 1 through the second mounting base 42. The second mounting base 42 is fixedly connected to the worktable 1 through the second connecting rod 43. The third driving element 41 is a cylinder, and the cylinder shell is fixed. The cylinder piston rod is parallel to the third direction and fixedly connected to the top wall of the first mounting base 61. The extension and retraction direction of the third elastic element 62 is parallel to the third direction. One end of the elastic element 62 is fixedly connected to the worktable 1, and the other end is directly or indirectly connected to the first mounting base 61. In this embodiment, the elastic element 62 is a compression spring. By setting the elastic element 62, the pressure plate 4 can receive the damping force of the elastic element 62 when it moves downward along the third direction, thereby reducing the rigid impact between the rotor and the pressure plate 4.

[0052] Reference Figure 2 To guide the sliding of the pressure plate 4 along a third direction, the buffer assembly 6 further includes a first guide rod 63. The first guide rod 63 is a telescopic rod structure. The movable section of the first guide rod 63 is fixedly connected to the bottom wall of the first mounting base 61, and the fixed section of the first guide rod 63 is fixedly connected to the worktable 1. The ends of the fixed section and the movable section of the first guide rod 63 that are close to each other are slidably connected along a third direction. An elastic element 62 is sleeved on the fixed section of the first guide rod 63, and the elastic element 62 is fixedly connected between the worktable 1 and the movable section of the first guide rod 63. The sliding of the pressure plate 4 is guided by the first guide rod 63. In this embodiment, the elastic element 62 is a compression spring.

[0053] Reference Figure 1 In order to drive the positioning gripper 32 to slide along the second direction, the positioning gripper 32 is driven by the fourth driving member 34. In some embodiments, the fourth driving member 34 can be driven by a worm gear, a lead screw, or a cylinder. Any driving structure that can realize the sliding of the positioning gripper 32 is within the protection scope of this application. In this embodiment, the fourth driving member 34 is a cylinder. The cylinder shell is fixedly connected to the worktable 1, and the cylinder piston rod is parallel to the second direction and fixedly connected to the unloading push rod 51. The fourth driving member 34 drives the positioning gripper 32 to slide along the second direction.

[0054] Reference Figure 3 To further improve the stability of the positioning gripper 32 in clamping the rotor, the positioning gripper 32 includes a positioning plate 321 and two arc-shaped plates 322 connected to the positioning plate 321. The two arc-shaped plates 322 have a positioning area 323 in a first direction. The arc-shaped openings of the two arc-shaped plates 322 are set towards the positioning area 323. The arc-shaped plates 322 are rotatably connected to the positioning plate 321 and elastically rotatably connected to the positioning plate 321. The arc-shaped plates 322 are parallel to the third direction along the rotation axis of the positioning plate 321. Under recoverable deformation, the arc-shaped plates 322 have a force that moves away from the positioning area 323. The ends of the arc-shaped plates 322 are arc-shaped, which facilitates the rotor entering the positioning area 323. The feeding pusher 31 pushes the rotor between the two arc-shaped plates 322. The arc-shaped plates 322 further increase the contact area with the rotor, further improving the stability of the rotor.

[0055] Reference Figure 3 When the feeding push rod 31 pushes the rotor to the bottom of the pressure plate 4, in order to further improve the stability of the rotor pushing process, the feeding push rod 31 is provided with a first arc groove 311 through the third direction on the side near the arc plate 322. The first arc groove 311 of the feeding push rod 31 increases the contact area with the rotor and improves the stability when pushing the rotor.

[0056] Reference Figure 4Because the rotor may have accumulated copper shavings, iron shavings, solder dross, dust, etc. on its surface (especially between the winding copper wires and commutator segments) during previous manufacturing processes (such as winding, welding, and handling), these debris, especially conductive metal debris, if left on the rotor and carried into the final product with the motor, may cause an electrical short circuit and lead to a safety accident. To clean the debris from the rotor, the motor rotor shaping device also includes a first cleaning component 7. In this embodiment, a first cleaning component 7 is provided on both sides of the pressure plate 4. The first cleaning component 7 includes... The device includes a suction nozzle 71, an air duct 72, and a fan 73. Multiple suction nozzles 71 are obliquely installed on the side wall of the pressure plate 4. The suction nozzles 71 are fixed to the pressure plate 4 by a mounting plate 74. The suction nozzles 71 are obliquely arranged towards the side closer to the pressure plate 4 along the direction close to the workbench 1. One end of the air duct 72 is connected to the suction nozzle 71, and the other end is connected to the fan 73. The fan 73 is installed on the first mounting base 61. In this embodiment, the air duct 72 is a flexible air duct. When the fan 73 is started, a negative pressure is generated in the air duct 72. The negative pressure in the air duct 72 forms a pressure difference with the external atmospheric pressure, thereby sucking the debris into the air duct 72 through the suction nozzles 71.

[0057] It should be noted that in this embodiment, the fan 73 is a miniature negative pressure fan. To further improve safety, the fan 73 is selected as an explosion-proof negative pressure fan, and the duct 72 is an anti-static duct.

[0058] Reference Figure 5 When the shaped rotor is pushed into the discharge chute 53 by the discharge pusher 51, in order to further clean the dust and debris on the rotor, the motor rotor shaping device also includes a second cleaning component 8. The second cleaning component 8 is disposed on the discharge chute 53. In this embodiment, two second cleaning components 8 are spaced apart along the width direction of the discharge chute 53. The second cleaning component 8 includes a cleaning plate 81 and a magnetic strip 82. Magnetic strips 82 are installed on both sides of the cleaning plate 81. The magnetic strips 82 are parallel to the length direction of the discharge chute 53. When the rotor passes between the two second cleaning components 8, the magnetic strips 82 can adsorb the iron filings adsorbed on the rotor, thereby improving the cleanliness of the rotor.

[0059] Reference Figure 5 Dust on the rotor may also adhere to the inner wall of the feeding slide 53. In order to further clean the inner wall of the feeding slide 53, the cleaning plate 81 slides along the width direction of the feeding slide 53, and the bottom wall of the cleaning plate 81 contacts the bottom wall of the feeding slide 53. When the bottom wall of the cleaning plate 81 slides along the width direction of the feeding slide 53, the rotor is less likely to be contaminated with debris again during the feeding process.

[0060] Reference Figure 5In order to improve the cleaning effect of the cleaning plate 81 on the material feeding slide 53, the cleaning plate 81 is inclined on the side close to the material feeding slide 53 so that the cleaning plate 81 and the material feeding slide 53 are in line contact, thereby improving the cleaning effect of the cleaning plate 81 on the dust on the inner wall of the material feeding slide 53.

[0061] Reference Figure 5 In order to drive the cleaning plate 81 to slide along the width direction of the feeding slide 53, the motor rotor shaping device also includes a drive assembly 9. The drive assembly 9 includes a motor 91 and a bidirectional screw 92. The bidirectional screw 92 is mounted on the side wall of the feeding slide 53 through a third mounting seat 93 and is fixedly connected to the feeding slide 53. Each third mounting seat 93 has a through slot 931 through the side wall near the feeding slide 53. The bidirectional screw 92 is rotatably connected to the third mounting seat 93. The axis of the bidirectional screw 92 and the axis of rotation are parallel to the width direction of the feeding slide 53. The motor housing is fixedly connected to the third mounting seat 93. The output shaft of the motor 91 is coaxially fixedly connected to the bidirectional screw 92. One end of the cleaning plate 81 is threadedly connected to the bidirectional screw 92. The cleaning plate 81 slides along the axial direction of the bidirectional screw 92.

[0062] Reference Figure 5 To guide the sliding of the cleaning plate 81 along the axis of the bidirectional screw 92, a second guide rod 94 is fixedly connected between the two third mounting bases 93. The second guide rod 94 is parallel to the bidirectional screw 92. The cleaning plate 81 is sleeved on the second guide rod 94 and slides along the length of the second guide rod 94. The motor 91 drives the bidirectional screw 92 to rotate, causing the two cleaning plates 81 to slide towards the side that is closer or farther apart. During the transportation or shaping process of the rotor, the motor 91 drives the cleaning plate 81 to slide towards the side that is farther apart, and the cleaning plate 81 cleans the discharge slide 53, thereby causing the dust on the bottom wall of the discharge slide 53 to fall to the outside through the through groove 931. The motor 91 then drives the cleaning plate 81 to slide towards the side that is closer together. After the shaped rotor passes through the discharge slide 53, the magnetic strip 82 on the cleaning plate 81 adsorbs the iron filings on the rotor.

[0063] It should be noted that the positions of the bidirectional screw 92 and the guide rod do not affect the rotor's passage through the feeding slide 53.

[0064] The implementation principle of the motor rotor shaping device in this application embodiment is as follows: The rotor is transported by the conveyor belt 2. When the rotor is transported to the position of the feeding push rod 31, the first driving member 33 drives the feeding push rod 31 to slide along the second direction, pushing the rotor to the bottom of the pressure plate 4. The fourth driving member 34 drives the positioning claw 32 to slide along the second direction. The positioning claw 32 and the feeding push rod 31 clamp and fix the rotor. The third driving member 41 drives the pressure plate 4 to slide in the third direction. The pressure plate 4 flattens and shapes the rotor, thereby shaping the uneven or local protrusions on the rotor end face. After shaping, the positioning claw 32 and the feeding push rod 31 slide along the second direction to the side away from each other. The second driving member 52 drives the unloading push rod 51 to slide along the first direction. The unloading push rod 51 pushes the rotor to the unloading slide 53, and further enters the collection point through the unloading slide 53.

[0065] When the rotor is clamped by the positioning gripper 32 and the feeding pusher 31, the negative pressure fan 73 is started, and the suction nozzle 71 adsorbs the dust and debris adsorbed on the rotor. After the rotor enters the unloading slide 53, the magnetic strip 82 adsorbs the iron filings on the rotor. The motor 91 drives the bidirectional screw 92 to rotate, which drives the two cleaning plates 81 to slide along the axis of the bidirectional screw 92. The cleaning plates 81 clean the dust and debris on the unloading slide 53.

[0066] 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.
