Description
Technical Field
[0001] This utility model relates to the field of motor processing technology, and in particular to a magnetic block assembly device for an external rotor. Background Technology
[0002] Traditional magnet assembly relies on manual insertion of magnets one by one into the rotor's magnet slots. Manual assembly is not only inaccurate and slow, but also carries the risk of worker error leading to magnet damage. With the continuous development of the electromechanical industry, some semi-automated magnet assembly machines have emerged. However, current market magnet assembly machines all use a single-slot insertion method. While this significantly improves efficiency compared to manual assembly, the strong magnetism of the magnets causes some positional shift during insertion, thus failing to meet the industry's current requirements for high precision and high speed. To address these issues, a solution is proposed below. Utility Model Content
[0003] The purpose of this invention is to provide a magnetic block assembly device for an external rotor, which has the advantages of high assembly accuracy and high working efficiency.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A magnetic block assembly device for an external rotor includes a frame. A guide seat is fixed to the upper end of the frame, and the guide seat has several guide grooves at equal angles. A support seat is fixed to the upper end of the guide seat. A magnetic insertion seat is fixed to the upper end of the frame, and the magnetic insertion seat has several magnetic insertion slots at equal angles. These magnetic insertion slots are respectively connected to the guide grooves. A mounting plate is provided on the inner side of the frame, and several pressure blocks are connected to the outer side of the mounting plate. Several through slots are opened at equal angles at the upper end of the frame, and the pressure blocks pass through these through slots and are slidably embedded in the magnetic insertion slots. A pushing mechanism is also provided inside the frame. The moving mechanism is connected to the mounting plate. Several support columns are fixed at the upper end of the frame. A top plate is connected to the upper end of the support columns. A first electric cylinder is installed at the upper end of the top plate. A moving plate is fixed to the output shaft of the first electric cylinder. Several pressure shafts are connected to the moving plate. Several guide sleeves are fixed on the top plate. Several pressure shafts are slidably inserted into the guide sleeves. A mounting plate is connected to the lower side of the pressure shafts. A limiting seat is provided below the mounting plate. A lifting mechanism is provided on the mounting plate and is connected to the limiting seat. Several limiting grooves are opened at equal angles on the limiting seat. The limiting grooves are respectively connected to several magnetic insertion grooves.
[0006] Preferably, the pushing mechanism includes a second electric cylinder, a plurality of connecting shafts are fixedly provided on the inner top of the frame, a connecting plate is fixedly provided at the lower end of the plurality of connecting shafts, and the second electric cylinder is installed at the lower end of the connecting plate. A push plate is provided above the connecting plate, and the output shaft of the second electric cylinder is fixedly connected to the push plate. The mounting plate is fixedly provided at the upper end of the push plate.
[0007] Preferably, the lifting mechanism includes a third electric cylinder, which is mounted on the upper end of the mounting plate. The output shaft of the third electric cylinder is fixedly connected to the upper end of the limiting seat. A plurality of sliding sleeves are fixedly provided on the mounting plate. Each sliding sleeve is provided with a sliding shaft, and the lower ends of the plurality of sliding shafts are fixedly connected to the upper end of the limiting seat.
[0008] Preferably, the connecting plate is fixed with several bushings, and the lower end of the push plate is connected with several guide shafts, which are slidably inserted into the bushings.
[0009] Preferably, an operation screen is installed on the top plate, and several support legs are installed at the lower end of the frame.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. When performing magnetization work on the outer rotor of the motor, simply place the outer rotor housing on the upper end of the support base. Then, the output shaft of the first electric cylinder can drive the moving plate to move up and down, thereby driving several pressure shafts to slide up and down along several guide sleeves. Thus, the pressure shafts can move down and make the lower ends of the pressure shafts abut against the upper surface of the outer rotor housing placed on the support base, thereby fixing the outer rotor housing.
[0012] 2. After the outer rotor housing is fixed, the magnetic blocks can be placed into several guide slots according to the actual number of magnetic blocks to be inserted. Then, the magnetic blocks can move along the guide slots and pass through the lower end of the support base, and finally enter the magnetic insertion base. At this time, the topmost magnetic block is located in the magnetic insertion slot. Then, the mounting plate can be moved upward by the pushing mechanism, which will drive several pressure blocks to move upward at the same time. Finally, the upper end of the pressure block can move upward along the magnetic insertion slot, thereby pushing the frontmost magnetic block upward, so as to push the magnetic block into the inner wall of the outer rotor housing, thus completing the assembly of the magnetic blocks.
[0013] 3. The lifting mechanism can drive the limit seat to move downward, so that the limit seat can enter the outer rotor housing. When the magnetic block is pushed upward, it can enter the limit groove. At this time, the limit groove can further limit the magnetic block to prevent the magnetic block from shifting position. This can further improve the accuracy of the magnetic block after assembly and greatly improve the practicality of the device. Attached Figure Description

[0019] like Figures 1 to 3 As shown, a magnetic block assembly device for an outer rotor includes a frame 1, a guide seat 2 fixed at the upper end of the frame 1, and a support seat 4 fixed at the upper end of the guide seat 2. When performing magnetic insertion work on the outer rotor of the motor, the outer rotor housing only needs to be placed on the upper end of the support seat 4. Several support columns 11 are fixedly mounted on the upper end of the frame 1. The upper ends of the support columns 11 are connected to a top plate 12. A first electric cylinder 13 is installed on the upper end of the top plate 12. A moving plate 14 is fixedly mounted on the output shaft of the first electric cylinder 13. Several pressure shafts 15 are connected to the moving plate 14. Several guide sleeves 16 are fixedly mounted on the top plate 12. The pressure shafts 15 are slidably inserted into the guide sleeves 16. The moving plate 14 can be driven to move up and down by the output shaft of the first electric cylinder 13, thereby driving the pressure shafts 15 to slide up and down along the guide sleeves 16. Therefore, the pressure shafts 15 can move downward and make the lower ends of the pressure shafts 15 abut against the upper surface of the outer rotor housing placed on the support base 4, thereby fixing the outer rotor housing.
[0020] The guide seat 2 has several guide grooves 3 at equal angles. A magnetic insertion seat 5 is fixed to the upper end of the frame 1. The magnetic insertion seat 5 has several magnetic insertion slots 6 at equal angles, each connected to one of the guide grooves 3. A mounting plate 7 is located inside the frame 1, and several pressure blocks 8 are connected to the outer side of the mounting plate 7. Several through slots 9 are opened at equal angles at the upper end of the frame 1, and the pressure blocks 8 pass through these through slots 9 and are slidably embedded within the magnetic insertion slots 6. A pushing mechanism 10 is also provided inside the frame 1, and the pushing mechanism 10 is connected to the mounting plate 7. When the outer rotation... After the sub-shell is fixed, the magnetic blocks can be placed into several guide grooves 3 according to the actual number of magnetic blocks to be inserted. Then the magnetic blocks can move along the guide grooves 3 and pass through the lower end of the support base 4, and finally enter the magnetic insertion base 5. At this time, the topmost magnetic block is located in the magnetic insertion groove 6. Then, the mounting plate 7 can be driven to move upward by the pushing mechanism 10, thereby driving several pressure blocks 8 to move upward at the same time. Finally, the upper end of the pressure block 8 can move upward along the magnetic insertion groove 6, thereby pushing the frontmost magnetic block upward, so as to push the magnetic block into the inner wall of the outer rotor shell, thereby completing the assembly of the magnetic blocks.
[0021] A mounting plate 17 is connected to the lower side of several pressure shafts 15. A limiting seat 18 is provided below the mounting plate 17. A lifting mechanism 19 is provided on the mounting plate 17 and is connected to the limiting seat 18. Several limiting grooves 20 are opened at equal angles on the limiting seat 18. The limiting grooves 20 are respectively connected to several magnetic insertion grooves 6. The lifting mechanism 19 can drive the limiting seat 18 to move downward, so that the limiting seat 18 can enter the outer rotor housing. When the magnetic block is pushed upward, it can enter the limiting groove 20. At this time, the limiting groove 20 can further limit the magnetic block to prevent the magnetic block from shifting position. This can further improve the accuracy of the magnetic block after assembly and greatly improve the practicality of the device.
[0022] The pushing mechanism 10 includes a second electric cylinder 21. Several connecting shafts 22 are fixedly installed on the inner top of the frame 1. A connecting plate 23 is fixedly installed at the lower end of the connecting shafts 22. The second electric cylinder 21 is installed at the lower end of the connecting plate 23.

[0023] Several bushings 28 are fixed on the connecting plate 23, and several guide shafts 29 are connected to the lower end of the push plate 24. The guide shafts 29 are slidably inserted into the bushings 28. When the push plate 24 moves up and down, it can drive the guide shafts 29 to slide up and down along the bushings 28. Therefore, the movement trajectory of the push plate 24 can be made straighter and more stable, which can further ensure the accuracy of the magnetic block insertion position.
[0024] The lifting mechanism 19 includes a third electric cylinder 25, which is mounted on the upper end of the mounting plate 17. The output shaft of the third electric cylinder 25 is fixedly connected to the upper end of the limiting seat 18. Several sliding sleeves 26 are fixedly mounted on the mounting plate 17.

The lower ends of the sliding shafts 27 are fixedly connected to the upper end of the limiting seat 18. When the limiting seat 18 moves up and down, it can drive the sliding shafts 27 to slide up and down along the sliding sleeves 26. Therefore, the movement trajectory of the limiting seat 18 is more straight and stable, and the position of the limiting seat 18 entering the outer rotor is more accurate, thereby ensuring the accuracy of the magnetic block insertion position.
