[0001] This utility model relates to the field of rotor riveting technology, and in particular to a rotary rotor riveting device. Background Technology

[0002] In electric motors and rotating machinery, the rotor is a key component for energy conversion or transmission, and its structural stability and operational reliability are of paramount importance. A rotor typically consists of core components such as a rotor shaft, iron core, and windings. To meet specific electrical performance, mechanical strength, or heat conduction requirements, copper rings are often installed on the rotor shaft. Copper rings have a wide range of applications, including but not limited to serving as short-circuit rings to eliminate vibrations caused by electromagnetic imbalances, as conductive rings to conduct current, and as heat dissipation rings to improve heat transfer efficiency.

[0003] In existing technologies, when using fixed single-station tooling, operators' hands can easily enter the machine's working area during manual feeding and material handling. Especially during riveting, if the operator's movements are not quick enough or the machine's safety protection measures are inadequate, hand crushing accidents can easily occur. Traditional fixed single-station tooling and manual feeding methods often lack effective safety protection measures, such as protective covers and safety doors, and cannot effectively prevent operators from entering dangerous areas.

[0031] Please see Figure 1 - Figure 7 A rotary rotor riveting device includes a rotary disk 1, a feeding mechanism 2 and a driving device 3. The rotary disk 1 has multiple placement slots 11 arranged around its circumference. Magnets 12 that attract rotor cores are arranged in the placement slots 11. The placement slots 11 include two parts: the inner part is used to install the magnets 12, and the outer part is arc-shaped to fit the rotor core.

[0032] The driving device 3 includes a drive motor 31 and an electric cylinder 32 that drive the rotating disk 1 to rotate. The drive motor 31 is fixed to the rotating disk 1, and a downward pressing column 33 is connected to the electric cylinder 32.

[0033] The feeding mechanism 2 includes a mounting block 21, on which a copper ring is located directly below the pressing column 33. The mounting block 21 is provided with a copper ring feeding channel 211. The feeding mechanism 2 also includes a worktable 22, on which a drive motor 31 is mounted. The mounting block 21 is fixed to the surface of the worktable 22. A fixing column 13 supporting the rotating disk 1 is fixed on the worktable 22. A lifting plate 23 is provided on the upper side of the mounting block 21. A through groove for the copper ring to pass through is opened on the lifting plate 23. A lifting cylinder 24 is provided on the lower side of the mounting block 21. The lifting cylinder 24 is installed inside the worktable 22. A lifting plate 25 passing through the mounting block 21 is fixed to the extended end of the lifting cylinder 24. The upper end of the lifting plate 25 is fixed to the lifting plate 23. When the pressing column 33 moves down, it causes the rotor to descend and the rotor shaft to be inserted into the copper ring. Finally, the rotor shaft and the copper ring are interference-fitted.

[0034] The feeding mechanism 2 also includes a feeding section 26, which includes a feeding cylinder 261 fixed on the worktable 22. The extended end of the feeding cylinder 261 is connected to a feeding plate 262 that moves within the feeding channel 211. A copper ring inlet 2621 is provided on one side of the feeding plate 262. Only one copper ring can be placed in the inlet 2621, and the copper ring is in contact with the inner wall of one side of the feeding channel 211, so that the position of the copper ring is stable. A vibratory feeder for feeding copper rings is provided on one side of the feeding section 26. The discharge end of the vibratory feeder is connected to the mounting block 21. The vibratory feeder is existing technology and is not shown in the figure.

[0035] A limiting block 27 fixed on the mounting block 21 is provided on one side of the lifting plate 23. The limiting block 27 and the placement groove 11 are located on both sides of the rotor. The limiting block 27 has an arc surface adapted to the surface of the rotor core. The limiting block 27 is used to limit the rotor from the other side when the rotor descends, so that the rotor can descend stably and thus keep the rotor shaft accurately inserted into the copper ring.

[0036] A positioning groove 14 is provided between two adjacent placement grooves 11. The positioning groove 14 is V-shaped in this application. Three placement grooves 11 and three positioning grooves 14 are used in this application to facilitate the insertion of positioning blocks 44. A positioning device 4 is provided on one side of the rotating disk 1. The positioning device 4 includes a support plate. A positioning cylinder 41 is fixed on the support plate. A guide block 42 is connected to the extended end of the positioning cylinder 41. A guide strip 43 is fixed on the support plate. The guide strip 43 is slidably connected to the guide block 42. A positioning block 44 adapted to the positioning groove 14 is fixed on the guide block 42. The guide strip 43 keeps the guide block 42 stable, thereby keeping the positioning block 44 stable. The rotating disk 1 is positioned by the cooperation of the positioning block 44 and the positioning groove 14, so that the rotor shaft is directly above the copper ring.

[0037] A support frame 34 supporting the electric cylinder 32 is provided on the workbench 22. A guide post 35 is fixed on the support frame 34. A guide body 36 is connected to the extended end of the electric cylinder 32. The guide body 36 is fixed to the pressing column 33, and the guide post 35 and the guide body 36 are slidably connected. Symmetrical top posts 37 are fixed to the lower end of the pressing column 33. There are two top posts 37. The gap between the two top posts 37 is used for the rotor shaft to pass through. The top posts 37 are used to abut against the end face of the rotor core. When the pressing column 33 contacts the rotor shaft, the top posts 37 simultaneously contact the end face of the rotor core, and thus press down simultaneously to maintain the stability of the rotor core and the rotor shaft.

[0038] In use, the rotor is manually placed into the placement slot 11, where it is attracted by the magnet 12. The operation is simple and convenient, and the hand does not need to enter the pressing range of the pressing column 33. After the rotor is attracted by the magnet 12, the drive motor 31 drives the rotating disk 1 to rotate, causing the rotor in the placement slot 11 to rotate directly below the pressing column 33. After the drive motor 31 stops, the positioning cylinder 41 moves the guide block 42, which in turn moves the positioning block 44. The positioning block 44 enters the positioning slot 14 to position the rotating disk 1, ensuring the rotor shaft is aligned with the copper ring. Before the pressing column 33 presses down, the vibrating plate vibrates to allow the copper ring to enter the inlet 2621. Then, the feeding cylinder 261 extends, and the feeding plate 262 moves with a copper ring. Finally, the copper ring moves to the underside of the lifting plate 23. Then, the electric cylinder 32 starts, causing the guide block 42 to move. The guide column 35 guides the guide body 36 downward, and the lowering column 33 and the top column 37 descend together. The top column 37 abuts against the end face of the rotor core, and the lowering column 33 abuts against the end face of the rotor shaft, causing the rotor to descend. After the rotor descends, the outer side is restricted by the limiting block 27, which plays a limiting role in the insertion of the rotor shaft into the copper ring, so that the rotor remains stable. The rotor shaft and the copper ring are connected by an interference fit. The electric cylinder 32 resets the lowering column 33 and the top column through the guide block 42. The lifting cylinder 24 is started, causing the lifting plate 25 and the top plate 23 to rise together. The top plate 23 pushes the rotor to rise. After the rotor is reset, the drive motor 31 continues to rotate, causing the rotor in the next placement slot 11 to rotate to the top of the mounting block 21. The rotor with the copper ring installed rotates out and is taken out, and then a new rotor without the copper ring installed is put in.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
