Description

Technical Field

[0001] This application relates to the technical field of surface treatment apparatus, and in particular to a surface treatment apparatus for an electric motor rotor. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to convert electrical energy into mechanical energy. An electric motor includes a rotor. During the production process of the rotor, its surface needs to be polished to ensure that the motor rotor and the motor mounting parts fit together precisely, so that the produced motor can run for a long time.

[0003] Currently, in the common motor rotor grinding process, after the rotor is conveyed to one side of the grinding machine, the chuck picks up the rotor and moves it to the output end of the grinding machine. Then, the grinding machine grinds the rotor. After the rotor is finished grinding, the chuck picks up the finished rotor and unloads it. This process is repeated to grind other rotors. However, this method of grinding rotors takes a lot of time, resulting in low production efficiency for rotor grinding. Summary of the Invention

[0004] To improve the production efficiency of rotor grinding, this application provides a motor rotor surface treatment device.

[0005] This application provides a surface treatment device for a motor rotor, which adopts the following technical solution:

[0006] A surface treatment apparatus for an electric motor rotor, comprising:

[0007] Work platform;

[0008] Conveyor Component: The conveyor component is located on the top of the work platform and is used to convey the rotor from the previous process to the top of the work platform.

[0009] Grinding mechanism: The grinding mechanism is used to grind the rotor;

[0010] First clamping unit: The first clamping unit is slidably connected to the top of the work platform. The first clamping unit is located at the top of the grinding mechanism. The first clamping unit includes a first unloading clamping component and a first loading clamping component. The first unloading clamping component is used to clamp the rotor unloading after grinding, and the first loading clamping component is used to clamp the rotor loading at the output end of the conveying component.

[0011] The transfer assembly is installed on the top surface of the work platform away from the conveying assembly. The transfer assembly is located on one side of the grinding mechanism and transfers the polished rotor to the next process.

[0012] By adopting the above technical solution, after the grinding mechanism finishes grinding the rotor, it simultaneously activates the first unloading clamping component and the first loading clamping component. The first unloading clamping component clamps the ground rotor, and the first loading clamping component clamps the rotor at the output end of the conveying component. The first unloading clamping component and the first loading clamping component move simultaneously towards one end of the transfer component until the first unloading clamping component is aligned with the input end of the transfer component. At this time, the first loading clamping component is aligned with the position where the grinding mechanism places the rotor. Then, the first unloading clamping component and the first loading clamping component are activated simultaneously. The first unloading clamping component places the clamped rotor at the input end of the transfer component for unloading, and correspondingly, the first loading clamping component places the clamped rotor on the grinding mechanism, so that the grinding mechanism can grind the next rotor that needs to be ground.

[0013] Therefore, this application performs unloading and loading simultaneously, which can reduce the time required for the rotor to go through loading, grinding, unloading and then loading the next rotor, thereby improving the production efficiency of rotor grinding.

[0014] Preferably, an installation platform is installed on the top of the work platform, the top surface of the installation platform is inclined towards the end near the grinding mechanism, a movable plate is slidably connected to the top surface of the installation platform, and the first clamping unit is installed at one end of the movable plate.

[0015] By adopting the above technical solution, the movable plate can move along the long side of the installation platform. By moving the movable plate, the first clamping unit is moved, so that the first unloading clamping component and the first loading clamping component can move synchronously.

[0016] Preferably, a motion drive component is installed on the side of the mounting platform away from the moving board, and the output end of the motion drive component is connected to one end of the moving board.

[0017] By adopting the above technical solution, the moving plate can be driven to move under the action of the moving drive component, thereby driving the first gripping unit on the moving plate to move.

[0018] Preferably, the first unloading clamping assembly includes a push drive, a sliding block, and a clamp. The push drive is mounted on the top surface of the mounting platform, the sliding block is slidably connected to the top surface of the moving plate, and the sliding block can move along the wide side of the mounting platform. The output end of the push drive is connected to one end of the sliding block, and the clamp is mounted on the end of the sliding block near the grinding mechanism.

[0019] By adopting the above technical solution, the drive component is activated, which can drive the sliding block to slide along the wide side of the mounting platform. The sliding block drives the gripper to move, thereby causing the gripper to pick up the rotor.

[0020] Preferably, there are two grinding mechanisms, which are distributed on both sides of the conveying component. There are also two transfer components, which are located on the side of the grinding mechanism closest to them that is away from the conveying component. A second clamping unit is provided at the end of the moving plate away from the first clamping unit. The first clamping unit is located on top of one grinding mechanism, and the second clamping unit is located on top of the other grinding mechanism.

[0021] By adopting the above technical solution, after the first clamping unit completes the placement of the rotor and retracts, another grinding mechanism completes the grinding of the rotor. At the same time, the second clamping unit is activated, which clamps the rotor at the output end of the conveying component and the rotor that has been ground by the other grinding mechanism. Then, the second clamping unit retracts, and the moving plate moves towards the conveying component end near the second unloading clamping component. Then, in the same way as the first clamping unit, the ground rotor is unloaded, and the next rotor that needs to be ground is placed in another grinding mechanism for grinding. This cycle continues.

[0022] By alternating the operation of the two grinding mechanisms, when one grinding mechanism is grinding the rotor, the other grinding mechanism, which has just finished grinding, can simultaneously load and unload materials. This allows for continuous and uninterrupted grinding of the rotors conveyed from the transmission assembly, thereby further improving the production efficiency of rotor grinding.

[0023] Preferably, the conveying assembly includes two limiting plates, which are arranged in parallel and at an angle. The end of the limiting plate closest to the working platform is the lower end of the horizontal plane, and the rotor is placed between the two limiting plates.

[0024] By adopting the above technical solution, the rotor is placed between two limiting plates. Then, under the action of the rotor's gravity, the rotor rolls downward along the long side of the limiting plates, thereby transferring the rotor from the previous process to the top of the work platform. This application utilizes the characteristics of the rotor itself for movement, which can save resources.

[0025] Preferably, the grinding mechanism includes a limiting component, which includes a limiting seat and a limiting post. The limiting post passes through the top of the side wall of the limiting seat. There are two limiting posts, which are arranged along the wide side of the limiting seat. There are two limiting seats, which are arranged opposite to each other. The rotor is placed on the top of the limiting post, and the limiting post limits the rotor.

[0026] By adopting the above technical solution, the rotor is placed on top of the limiting post, and one side of the limiting post abuts against the side wall of the rotor, thereby achieving the function of supporting and limiting the rotor, which facilitates the grinding of the rotor.

[0027] Preferably, the limiting component further includes an abutment post, which is installed on the top of a limiting seat, with one end of the abutment post abutting against one end of the rotor.

[0028] By adopting the above technical solution, the rotor can be further limited under the action of the abutment column. When the grinding mechanism grinds the outer wall of the rotor, and at the same time, the grinding block moves towards one end of the abutment column, the abutment column can press against the rotor, thereby reducing the situation where the rotor moves due to the force applied by the grinding block to the rotor. At the same time, it can also reduce the situation where the limiting column causes damage to the rotor.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. After the grinding mechanism finishes grinding the rotor, it simultaneously activates the first unloading clamping component and the first loading clamping component. The first unloading clamping component clamps the ground rotor, and the first loading clamping component clamps the rotor at the output end of the conveying component. The first unloading clamping component and the first loading clamping component move towards one end of the transfer component until the first unloading clamping component is aligned with the input end of the transfer component. At this time, the first loading clamping component is aligned with the position where the grinding mechanism places the rotor. Then, the first unloading clamping component and the first loading clamping component are activated simultaneously. The first unloading clamping component places the clamped rotor at the input end of the transfer component for unloading. Correspondingly, the first loading clamping component places the clamped rotor onto the grinding mechanism, so that the grinding mechanism can grind the next rotor that needs to be ground.

[0031] Therefore, this application performs unloading and loading simultaneously, which can reduce the time required for the rotor to go through loading, grinding, unloading and then loading the next rotor, thereby improving the production efficiency of rotor grinding.

[0032] 2. After the first clamping unit finishes placing the rotor and retracts, another grinding mechanism finishes grinding the rotor. At the same time, the second clamping unit is activated. The second clamping unit clamps the rotor at the output end of the conveying component and the rotor that has been ground by the other grinding mechanism. Then, the second clamping unit retracts, and the moving plate moves towards the conveying component end near the second unloading clamping component. Then, in the same way as the first clamping unit, the ground rotor is unloaded. The next rotor that needs to be ground is placed in another grinding mechanism for grinding, and this cycle continues.

[0033] By alternating the operation of the two grinding mechanisms, when one grinding mechanism is grinding the rotor, the other grinding mechanism, which has just finished grinding, can simultaneously load and unload materials. This allows for continuous and uninterrupted grinding of the rotors conveyed from the transmission assembly, thereby further improving the production efficiency of rotor grinding.

[0038] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0039] This application discloses a surface treatment device for an electric motor rotor.

[0040] Reference Figure 1 and Figure 2 A surface treatment device for an electric motor rotor includes a working platform 1, a conveying assembly 2 on the top surface of the working platform 1, and a limiting plate 21. In this embodiment, the limiting plate 21 is an "L"-shaped plate. A support base is fixedly installed on the top surface of the working platform 1, and the limiting plate 21 is fixed on the top surface of the support base. One end of the limiting plate 21 extends to the output end of the previous process. The limiting plate 21 is inclined and tilted from top to bottom along its long side. The end of the limiting plate 21 near the working platform 1 is the end with the lower horizontal plane. There are two limiting plates 21, and the openings of the two limiting plates 21 are opposite and parallel. A placement space for placing a rotor 8 is reserved between the two limiting plates 21. A baffle 22 is fixed between the two limiting plates 21 and is located at the end of the limiting plate 21 near the working platform 1. The baffle 22 seals the bottom end of the placement space. The rotor 8 includes a rotor body and two rotating shafts 82. The two rotating shafts 82 are respectively installed on both sides of the rotor body.

[0041] The rotor 8 is placed on the conveying assembly 2 from the output end of the previous process. The bottom of the rotor 8 body is located in the placement space, and the two rotating shafts 82 are respectively located on the top surface of the limiting plate 21 that is close to it. Then, under the action of the gravity of the rotor 8, the rotor 8 rolls down along the long side of the limiting plate 21 until the rotor 8 abuts against one side of the baffle 22. The baffle 22 blocks the rotor 8 from continuing to move downward, so that the baffle 22 stops on one side, thereby transferring the rotor 8 from the previous process to the top of the working platform 1.

[0042] A support platform 11 is fixed on the top surface of the work platform 1. The long side of the support platform 11 is parallel to the wide side of the work platform 1. A grinding mechanism 3 is provided on the top surface of the support platform 11. The grinding mechanism 3 includes a rotating unit 31. The rotating unit 31 includes a housing 311 and a rotation drive assembly. The housing 311 is rotatably connected to the top of the support platform 11. The rotation drive assembly includes an output motor 312 and a rotating roller. The output motor 312 is installed on the top surface of the work platform 1. The rotating roller is rotatably connected inside the housing 311. Pulleys are fixed on the output shaft of the output motor 312 and the rotating roller. The two pulleys are linked by a belt. The rotating roller is driven to rotate continuously by turning on the output motor 312.

[0043] Reference Figure 1 and Figure 2 The rotating unit 31 also includes a pressure belt 313. The end of the rotating roller away from the pulley and the output end inside the housing 311 are both equipped with pulleys. The two ends of the pressure belt 313 are respectively sleeved on the outer walls of the two pulleys. The rotating roller rotates, thereby driving the pulleys and the pressure belt 313 to rotate.

[0044] A spring 314 is connected to one end of the housing 311 away from the pressure belt 313. The other end of the spring 314 is fixed to one end of the top surface of the work platform 1. A lifting drive component is installed on the top surface of the work platform 1. In this embodiment, the lifting drive component is a lifting drive cylinder. The output end of the lifting cylinder 315 extends out of the top surface of the support platform 11, and the output end of the lifting cylinder 315 is aligned with the bottom of the end of the housing 311 away from the pressure belt 313.

[0045] The polishing mechanism 3 also includes a polishing unit 32, which is arranged opposite to the rotating unit 31. The polishing unit 32 includes a polishing assembly, which includes a mounting block 321, a housing 322, and a polishing block 323. The mounting block 321 is slidably connected to the top surface of the support platform 11 and can move along the wide side of the support platform 11. The housing 322 is slidably connected to the top surface of the mounting block 321 and can move along the long side of the support platform 11. The polishing block 323 is installed on the top surface of the housing 322 near the end of the pressure band 313.

[0046] The grinding unit 32 also includes a limiting component, which is disposed between the pressure belt 313 and the grinding component. The limiting component includes a limiting seat 324 and a limiting post 325. The limiting seat 324 is installed on the top surface of the support platform 11. The limiting post 325 passes through the top of the side wall of the limiting seat 324. There are two limiting posts 325, which are arranged along the wide side of the limiting seat 324. There is a gap between the two limiting posts 325. Correspondingly, there are two limiting seats 324, which are arranged opposite to each other. A space is reserved between the two limiting seats 324 for placing the rotor 8 body. The rotating shaft 82 is placed between the tops of the two limiting posts 325. One side of the limiting post 325 abuts against the side wall of the rotor 8 body, thereby achieving the function of supporting and limiting the rotor 8.

[0047] Reference Figure 1 and Figure 2 When the rotor 8 needs to be polished, first place the rotor 8 on top of the two limit seats 324. Then, start the lifting cylinder 315. The output end of the lifting cylinder 315 pushes one end of the bottom of the housing 311, so that the end of the housing 311 near the pressure belt 313 moves downward until the outer wall of the pressure belt 313 presses against the outer wall of the rotor 8. At this time, the spring 314 is in a stretched state. At the same time, the outer shell 322 drives the polishing block 323 to move towards the end near the limit seat 324 until the output end of the polishing block 323 abuts against the outer wall of the rotor 8. Then, start the rotation drive assembly. The rotation drive assembly drives the pressure belt 313 to rotate. The rotation of the pressure belt 313 drives the rotor 8 to rotate, so that the polishing block 323 can polish the outer wall of the rotor 8. When the polishing block 323 polishes the outer wall of the rotor 8, the mounting block 321 moves along the wide side of the support platform 11, so that the outer wall of the rotor 8 is polished more thoroughly.

[0048] After the rotor 8 finishes grinding, the rotation drive assembly stops working, the output end of the lifting cylinder 315 retracts downward, and during the process of the spring 314 restoring its deformation, the spring 314 pulls one end of the housing 311 downward, thereby causing the pressure belt 313 to move upward until it is away from the outer wall of the rotor 8 body. At the same time, the housing 322 drives the grinding block 323 to move away from the limit seat 324, and the mounting block 321 drives the housing 322 to move back to its original position.

[0049] Reference Figure 3The limiting component also includes an abutment post 326, which is fixed on the top of a limiting seat 324. The abutment post 326 is located on the limiting seat 324 in the direction of movement of the mounting block 321 when the rotor 8 is being ground. One end of the abutment post 326 abuts against one end of a rotating shaft 82. Under the action of the abutment post 326, the rotor 8 can be further limited. When the grinding block 323 grinds the outer wall of the rotor 8 body, and at the same time, the grinding block 323 moves towards the abutment post 326, the abutment post 326 can press against the rotating shaft 82, thereby reducing the situation where the grinding block 323 applies force to the rotor 8 body and causes the rotor 8 to move. At the same time, it can also reduce the situation where the limiting post 325 causes damage to the rotor 8 body.

[0050] The top of the work platform 1 is equipped with a transfer component 4. The structure of the transfer component 4 is consistent with the structure of the conveying component 2. In this embodiment, it will not be described in detail. The transfer component 4 is located at the end of the grinding mechanism 3 away from the conveying component 2. The input end of the transfer component 4 is located on one side of the grinding mechanism 3, and the output end of the transfer component 4 is located at the input end of the next process. After the rotor 8 finishes grinding, the rotor 8 is placed on the transfer component 4 and conveyed to the next process.

[0051] Reference Figure 1 and Figure 2 In this embodiment of the application, there are two grinding mechanisms 3, which are distributed on both sides of the conveying component 2. Correspondingly, there are two transfer components 4, which are located on the side of the grinding mechanism 3 that is close to it and away from the conveying component 2.

[0052] A mounting platform 12 is provided on the top of the working platform 1. The mounting platform 12 is located at the end of the working platform 1 away from the rotating unit 31 and is located on top of the grinding mechanism 3. The top surface of the mounting platform 12 is inclined from top to bottom along one end of the rotating unit 31. A clamping mechanism is provided on the top surface of the mounting platform 12. The clamping mechanism includes a movable plate 5, which is slidably connected to the top surface of the mounting platform 12. The long side of the movable plate 5 is parallel to the long side of the mounting platform 12. The movable plate 5 can move along the long side of the mounting platform 12. A moving drive component is provided on the side of the mounting platform 12 away from the movable plate 5. In this embodiment, the moving drive component is a moving cylinder. The moving cylinder is installed on the side of the mounting platform 12 away from the moving plate 5. The output end of the moving cylinder is assembled with one end of the moving plate 5. When the moving cylinder is activated, it can drive the moving plate 5 to move along the long side of the mounting platform 12.

[0053] The clamping mechanism includes a first clamping unit 6, which includes a first unloading clamping assembly 61. The first unloading clamping assembly 61 includes a push drive, a sliding block 612, and a gripper 613. In this embodiment, the push drive is a push cylinder 611, which is mounted on the top surface of the mounting platform 12. The sliding block 612 is slidably connected to the top surface of the moving plate 5 and can move along the width of the mounting platform 12. The output end of the push cylinder 611 is connected to one end of the sliding block 612. When the push cylinder 611 is activated, it can drive the sliding block 612 to slide along the width of the mounting platform 12. The gripper 613 is mounted on the end of the sliding block 612 near the grinding mechanism 3. When the push cylinder 611 is in the extended state, the gripper 613 is aligned with the top of a limiting assembly and can clamp the rotor 8 located on the top of the limiting assembly.

[0054] Reference Figure 1 The first clamping unit 6 also includes a first feeding clamping component 62, which is located on one side of the first unloading clamping component 61. The structure of the first feeding clamping component 62 is consistent with the structure of the first unloading clamping component 61. In this embodiment, it will not be described in detail. The distance between the first feeding clamping component 62 and the first unloading clamping component 61 is adapted to the distance between the limiting seat 324 and the conveying component 2. When the first unloading clamping component 61 is aligned with the rotor 8 on the limiting seat 324, the output end of the first feeding clamping component 62 is aligned with the rotor 8 at the output end of the conveying component 2.

[0055] After the rotor 8 at the top of the limiting seat 324 is polished, the first unloading clamping assembly 61 and the first loading clamping assembly 62 are simultaneously activated. The first unloading clamping assembly 61 clamps the rotor 8 at the top of the limiting seat 324, and the first loading clamping assembly 62 clamps the rotor 8 at the output end of the conveying assembly 2. After the first unloading clamping assembly 61 and the first loading clamping assembly 62 retract, the moving cylinder is activated. The moving cylinder drives the moving plate 5 to move towards the end of the transfer assembly 4 near the first unloading clamping assembly 61, until the first unloading clamping assembly 61 is engaged. The material clamping component 61 is aligned with the input end of the transfer component 4. At this time, the first loading clamping component 62 is aligned with the position of the limiting seat 324 where the rotor 8 is placed. Then, the first unloading clamping component 61 and the first loading clamping component 62 are started simultaneously. The first unloading clamping component 61 places the clamped rotor 8 to the input end of the transfer component 4 for unloading. Correspondingly, the first loading clamping component 62 places the clamped rotor 8 on the top of the limiting seat 324, so that the grinding mechanism 3 grinds the next rotor 8 that needs to be ground.

[0056] Therefore, this application performs unloading and loading simultaneously, which can reduce the time for the rotor 8 to go through loading, grinding, unloading and then loading the next rotor 8, thereby improving the production efficiency of rotor 8 grinding.

[0057] The clamping mechanism also includes a second clamping unit 7, which includes a second feeding clamping component 71 and a second unfeeding clamping component 72. The structure of the second clamping unit 7 is consistent with the structure of the first clamping unit 6. In this embodiment, it will not be described in detail. When the first unfeeding clamping component 61 clamps the rotor 8 and aligns it with the transfer component 4 for unfeeding, and the first feeding clamping component 62 clamps the rotor 8 and aligns it with the nearby grinding mechanism 3 for feeding, the second feeding clamping component 71 aligns with the rotor 8 at the output end of the transfer component 2, and the second unfeeding clamping component 72 aligns with the rotor 8 being ground by another grinding mechanism 3.

[0058] Reference Figure 1 After the first clamping unit 6 completes the placement of the rotor 8 and retracts, another grinding mechanism 3 completes the grinding of the rotor 8. At the same time, the second loading clamping assembly 71 and the second unloading clamping assembly 72 are activated. The second loading clamping assembly 71 clamps the rotor 8 at the output end of the conveying assembly 2, and the second unloading clamping assembly 72 clamps the rotor 8 that has been ground by the other grinding mechanism 3. Then, the second clamping unit 7 retracts, and the moving plate 5 moves towards the conveying assembly 2 end close to the second unloading clamping assembly 72. Then, in the same way as the first clamping unit 6, the ground rotor 8 is unloaded, and the next rotor 8 that needs to be ground is placed in another grinding mechanism 3 for grinding. This cycle continues.

[0059] By alternating the operation of the two grinding mechanisms 3, when one grinding mechanism 3 is grinding the rotor 8, the other grinding mechanism 3 that has finished grinding is simultaneously fed and unloaded, so that the rotor 8 conveyed from the conveying component 2 can be ground continuously and uninterruptedly, thereby further improving the production efficiency of rotor 8 grinding.

[0060] The above are all preferred embodiments of this application. These embodiments are merely explanations 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.
