Description

Technical Field

[0001] The invention relates to the technical field of rolling machines, in particular to a motor end ring rolling machine. Background Art

[0002] The motor end ring is a metal ring used at the end of the motor stator or rotor, usually made of copper or aluminum. Its main function is to provide uniform distribution of current and mechanical stability. The appearance of the end ring is usually a round or ring-shaped metal sheet, which may have some holes or slots for connection or fixation with other parts. Rolling processing is a process of forming smooth fillets or strengthening edges on the edge of the workpiece by rolling. It can increase the strength and rigidity of the end ring and reduce deformation or damage caused by vibration and stress concentration during the operation of the motor. The edge of the end ring after rolling processing is smoother, which reduces the electro-corrosion or arcing caused by current concentration and improves the electrical performance.

[0003] During the hemming process, the motor end ring to be processed is fixed in the fixture or mold of the hemming machine to ensure that it will not move during the process. The roller begins to roll along the edge of the end ring. The roller applies a certain amount of pressure through a mechanical or hydraulic system, so that the edge of the end ring gradually forms a preset shape. The traditional motor end ring hemming machine mainly relies on two roller structures to roll the end ring, and uses the rotating motion of the roller to apply a shaping downward pressure on the surface of the end ring to make the surface of the end ring smooth and formed. However, this passive motion processing method has many defects: since the end ring is passively moving, it is difficult to achieve precise positioning, resulting in poor accuracy and consistency of hemming; during the rolling process, the end ring is unevenly stressed, and edge deformation or irregularity is prone to occur, affecting the quality of the finished product; the passive motion method limits the processing speed, especially under the requirements of high precision and high output, and cannot meet the efficiency requirements of modern production; the friction between the roller and the end ring is large, resulting in increased wear of the roller and the end ring, increasing the maintenance cost and downtime of the equipment.

[0004] In view of this, research and improvement are carried out on the existing problems, and a motor end ring rolling machine is provided to solve the current problems. The purpose is to solve the problems and improve the practical value through this technology. Summary of the invention

[0031] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0032] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0033] A motor end ring rolling machine provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0034] Combination Figure 1-7As shown, a motor end ring hemming machine provided by the present invention comprises: a track frame 100, a rolling assembly 200, a moving tooling assembly 300 and a clamping assembly 400, and a rolling stand 110 and a slide seat 120 slidably mounted on the surface of the track frame 100, the rolling assembly 200 comprises two lifting guide seats 210 slidably mounted on the inner side of the rolling stand 110 and a screw assembly 220 for driving the two lifting guide seats 210 to slide relative to each other, a rolling head 230 which is rotatably mounted on the surface of the lifting guide seat 210 and is transmission-connected to the output end of the reduction drive box 130, the moving tooling assembly 300 comprises a fixed seat 310, a supporting seat 340 and a supporting guide wheel 350, and a first driving motor 320 and a second driving motor 330 which are respectively fixedly mounted on both ends of the fixed seat 310, a rudder gear 341 is provided on one side of the supporting seat 340 and is rotationally mounted on the surface of the fixed seat 310, and the output end of the first driving motor 320 is connected to the surface of the rudder gear 341 by belt transmission;

[0035] A main shaft 343 and a worm shaft 344 are rotatably mounted on the surface of the support seat 340, and a worm is provided at the output end of the second drive motor 330 which is transmission-connected to the surface of the worm shaft 344. There are two clamping assemblies 400 which are fixedly mounted on one side of the support seat 340 and symmetrically arranged about the center line of the support guide wheel 350, and the clamping assemblies 400 are used to abut against the circumferential side of the motor end.

[0036] In this embodiment, the rolling die 230 has a conical structure and the opposite surfaces of the two rolling die 230 are arranged parallel to each other, and the surface of the rolling die 230 is provided with an annular groove for forming the motor end ring.

[0037] Specifically, by setting different annular grooves on the surface of the rolling die head 230 to roll-form the edge of the motor end ring, different rolling die heads 230 can be replaced to achieve different rolling edge processing.

[0038] In this embodiment, the screw assembly 220 includes a screw and a reduction motor fixed to the top surface of the rolling frame 110. The lifting guide seat 210 is slidably installed on the inner side of the rolling frame 110, and the two lifting guide seats 210 are respectively provided with threaded sleeve holes that are compatible with the surface of the screw and in opposite directions.

[0039] Specifically, the two lifting guide seats 210 and the rolling head 230 are driven by the screw assembly 220 to move relative to each other to apply pressure to the rolled motor end ring to form it by rolling.

[0040] In this embodiment, the first driving motor 320 and the second driving motor 330 are located on the same axis and are used for deflection driving of the support seat 340 and rotation driving of the support guide wheel 350 respectively.

[0041] In this embodiment, the main shaft rod 343 and the worm shaft rod 344 are connected by a pulley and a belt transmission located inside the support seat 340. A sliding cover plate 342 is provided on the surface of the support seat 340, and the end of the main shaft rod 343 passes through the surface of the sliding cover plate 342 and is fixedly connected to the support guide wheel 350.

[0042] Specifically, the transmission connection between the second drive motor 330 and the main shaft 343 is achieved by utilizing the transmission of the worm shaft 344 and the main shaft 343 .

[0043] In this embodiment, the top surface of the sliding cover plate 342 is a smooth and polished structure, and the main shaft rod 343 is arranged perpendicular to the surface of the sliding cover plate 342 .

[0044] Specifically, the motor end ring is supported by the sliding cover plate 342 so that the motor end ring can freely rotate, slide, and perform other movements.

[0045] In this embodiment, the clamping assembly 400 includes a positioning seat 410 and a dynamic chuck 420 and a driving rod 430 rotatably mounted on the surface of the positioning seat 410, the surface of the driving rod 430 and the output end of the driving rod 430 are rotatably connected to the surface of the positioning seat 410 and the surface of the dynamic chuck 420, respectively, and a wheel-resisting rod 440 is rotatably mounted on the other end of the dynamic chuck 420, and a pressure pad 441 for crimping the motor end ring is provided at the top of the wheel-resisting rod 440.

[0046] Furthermore, the surface of the wheel-repelling rod 440 is provided with a roller seat connected to the surface of the dynamic chuck 420, and the rotation direction of the roller seat and the surface of the dynamic chuck 420 is the same as the rotation direction of the connection point between the positioning seat 410 and the dynamic chuck 420. The wheel-repelling rod 440 is rotatably installed on the roller seat and the rotation direction is the same as the rotation direction of the support guide wheel 350.

[0047] Specifically, the driving rod 430 drives the dynamic chuck 420 to deflect so that the wheel-repelling rod 440 abuts against the surface of the motor end ring and the pressure pad 441 presses against the top surface of the motor end ring, thereby realizing the tooling clamping of the motor end ring. The motor end ring can abut and transmit rotation on the surfaces of the support guide wheel 350 and the wheel-repelling rod 440 when in contact with the support guide wheel 350.

[0048] The working principle and use process of the present invention:

[0049] During the rolling hemming process of the motor end ring, the motor end ring is sleeved on the surface of the supporting guide wheel 350, and the driving rod 430 drives the dynamic clamp 420 to deflect so that the wheel rod 440 abuts against the surface of the motor end ring and the pressure pad 441 presses the top surface of the motor end ring to realize the tooling clamping of the motor end ring, and the sliding slide 120 moves the rolling assembly 200 so that one side of the motor end ring approaches and enters the action range of the two rolling heads 230, and the lifting guide seat 210 is lifted and lowered under the drive of the screw rod assembly 220, and the rolling head 230 contacts and rolls the surface of the motor end ring to start the rolling work. By replacing different rolling head 230 structures and coordinating the support seat 340 and the clamping assembly 400 to adjust the inclination angle of the motor end ring, the equipment can be compatible with more types and sizes of motor end rings, adapt to different processing requirements, improve the versatility of the equipment, and be able to process end rings of different sizes and shapes, reducing the number of equipment replacement and adjustment times;

[0050] During rolling, the first drive motor 320 can drive the rudder gear 341 and the support seat 340 to deflect on the surface of the fixed seat 310 as a whole, thereby driving the motor end ring to deflect. The inclination angle of the motor end ring can be adjusted by the tooling structure, so that the contact angle between the motor end ring and the surface of the rolling structure can be changed, thereby performing processing at different angles, improving processing flexibility, and adapting to different processing requirements. When the angle of the motor end ring changes, the force and friction during the processing can be optimized, which can reduce equipment wear and extend the service life of the rolling equipment and fixture. During the rolling process, the second drive motor 330 is used to drive the support guide wheel 350 to rotate and drive the support guide wheel 350 to rotate. In the clamping tooling of the clamping assembly 400, the motor end ring can rotate synchronously with the rolling structure, and its position and speed can be accurately controlled to ensure consistency and accuracy in the rolling process and ensure that the end ring is subjected to uniform pressure during the rolling process.
