Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and more specifically, to a grinding device for processing motor stator laminations. Background Technology

[0002] The stator of an electric motor is an important component of motors such as generators and starters. Existing stator cores are usually made by overlapping and welding multiple stator laminations of the same shape. After the stator laminations are cut and drilled, they often need to be ground. For example, the grinding device for processing electric motor stator laminations proposed in application number "CN202221902488.3" includes a base plate and a mounting plate. The mounting plate is mounted on the base plate and is provided with a positioning mechanism and a grinding mechanism. The positioning mechanism includes two sets of positioning grooves and support wheels, and the grinding mechanism includes two sets of grinders and sliding plates. The two sets of grinders are mounted on the corresponding sliding plates. However, in the above technical solutions, the grinding position can only be adjusted by manually rotating the motor blades during the grinding process. There is a lack of automatic conveying and position adjustment structure. When it is necessary to continuously grind different areas of the stator blades, manual operation not only increases the labor intensity, but also easily affects the grinding accuracy due to the deviation of the rotation angle. It is difficult to meet the needs of batch and high-precision stator blade grinding. Therefore, we propose a grinding device based on motor stator blade processing to solve the above problems.

[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) In this utility model, an automatic conveying structure is set up by a drive wheel, a driven wheel and a third motor. The third motor can drive one of the drive wheels to rotate. Then, with the help of the transmission of the fourth sprocket and the second chain, the two drive wheels can rotate synchronously. With the help of the driven wheel, the material can be moved stably. This not only greatly reduces the labor intensity of the workers, but also avoids the problem of rotation angle deviation in manual operation, ensures the accuracy of the stator plate grinding area, effectively improves the precision consistency during batch grinding, and meets the high precision stator plate processing requirements.

[0011] (2) In this utility model, on the one hand, the hydraulic cylinder on the bracket can drive the placement frame to move up and down, thereby adjusting the distance between the driving wheel and the driven wheel, which can stably clamp stator plates of different thicknesses. On the other hand, the first motor in the placement frame drives the positive and negative lead screws to rotate. Under the limiting action of the guide rod, the two sliders can move synchronously in opposite directions along the slide groove, thereby adjusting the distance between the two sets of first grinding rollers to adapt to the grinding of the front and rear sides of stator plates of different widths. At the same time, the movable rod under the bearing seat in the support frame cooperates with the spring to ensure that the second grinding roller is always in close contact with the surface of the stator plate. Even if there are slight unevennesses on the surface of the stator plate, they can be adjusted adaptively by the elasticity of the spring to further ensure the uniformity of the grinding effect.

The lower end of the slider 503 is respectively installed with a second motor 506. The output end of the second motor 506 is respectively installed with a first grinding rod 507. The first grinding rod 507 is located at the front and rear ends of the raw material 4, and the first grinding rod 507 is in contact with the front and rear sides of the raw material 4. The rotating shaft 511 is movably installed in the middle of the support frame 2. The second grinding rod 512 is sleeved on the outside of the shaft of the rotating shaft 511 and is in contact with the surface of the raw material 4.

[0016] like Figures 4 to 10As shown, in another embodiment of this utility model, a fourth sprocket 11 is installed on the outer side of the rod at the front end of the drive wheel 7, and a second chain 12 is sleeved between the fourth sprockets 11. A hydraulic cylinder 9 is installed on the upper surface of the bracket 8. The output end of the hydraulic cylinder 9 movably passes through the interior of the bracket 8 and is connected to the placement frame 6. A third motor 10 is installed at one rear end of the placement frame 6. The output end of the third motor 10 movably passes through the interior of the placement frame 6 and is connected to one of the drive wheels 7. A groove 501 is provided in the middle of the upper end of the placement frame 6. The upper ends of the sliders 503 are movably installed in the groove 501. Guide rods 502 are installed at both ends of the groove 501. The rods of the guide rods 502 movably pass through the interior of the sliders 503. A positive and negative lead screw 505 is movably installed in the middle of the groove 501. The rods of the positive and negative lead screws 505 are respectively threaded and inserted into the interior of the sliders 503. A first The output end of the first motor 504 is connected to the positive and negative lead screws 505. Bearing seats 509 are movably installed on the front and rear sides of the lower end of the support frame 2. The shaft of the rotating shaft 511 is installed through the inside of the bearing seat 509. Movable rods 508 are installed on the lower surface of the bearing seat 509. The shaft of the movable rod 508 is movably installed through the inside of the worktable 1. Springs 510 are sleeved on the outer side of the shaft of the movable rod 508 located between the worktable 1 and the bearing seat 509. A third sprocket 516 is installed at the rear end of the shaft of the rotating shaft 511. A first sprocket 513 is installed at the rear end of the shaft of one of the driven wheels 3. A first chain 517 is sleeved between the first sprocket 513 and the third sprocket 516. A connecting rod 515 is installed on the rear side of the inside of the support frame 2 and near the first chain 517. A second sprocket 514 is movably installed at the front end of the connecting rod 515. The second sprocket 514 is engaged inside the first chain 517.

[0017] The user first places the raw material 4 onto the driven wheel 3. As the raw material 4 is inserted into the driven wheel 3, the lower end of the raw material 4 pushes the second grinding roller 512 downward. Then, the second grinding roller 512 drives the rotating shaft 511 to move, causing the rotating shaft 511 to drive the bearing seat 509 and the movable rod 508 downward, and compressing the spring 510. The spring 510 pushes the second grinding roller 512 to always be in contact with the raw material 4. At the same time, the rotating shaft 511 also drives the third sprocket 516 to move. The second sprocket 514 is used to compensate the first chain 517 when the third sprocket 516 moves up and down, ensuring that the first sprocket 513, the second sprocket 514 and the third sprocket 516 can always transmit power. Then, the hydraulic cylinder 9 installed on the bracket 8 is activated. The output end of the hydraulic cylinder 9 pushes the placement frame 6 to move down until the drive wheel 7 inside the placement frame 6 is in contact with the upper end of the raw material 4 to complete the positioning of the raw material 4. Then, the first motor 504 is activated. The output end of the first motor 504 drives the positive and negative lead screws 505 inside the slide groove 501 to rotate. Under the limiting action of the guide rods 502 at both ends of the slide groove 501, the two sliders 503 move closer or further away from each other along the slide groove 501 in sync, and finally the sliders 503 drive the first grinding roller 507 to contact the front and rear sides of the raw material 4. After the raw material 4 is installed and the position of the first polishing roller 507 is adjusted, the user can start the third motor 10. The output end of the third motor 10 drives one of the drive wheels 7 to rotate. The fourth sprocket 11 on the outer side of the front end of the drive wheel 7 drives the other drive wheel 7 to rotate synchronously through the second chain 12. When the drive wheel 7 controls the raw material 4 to rotate, the raw material 4 will also drive the driven wheel 3 to rotate passively, assisting the raw material 4 to rotate. Then, the second motor 506 is started, and the second motor 506 drives the first polishing roller 507 to rotate, so as to achieve the polishing work on the front and rear sides of the raw material 4. Then, when the driven wheel 3 assists the raw material 4 to rotate, the first sprocket 513 of the rod at the rear end of the driven wheel 3, through the first chain 517, cooperates with the second sprocket 514 at the front end of the connecting rod 515 on the rear side of the support frame 2 to drive the third sprocket 516 at the rear end of the rotating shaft 511 to rotate, thereby causing the second grinding roller 512 on the outer side of the rotating shaft 511 to rotate synchronously and grind the surface of the raw material 4. During this process, the spring 510 on the outer side of the movable rod 508 on the lower surface of the bearing seat 509 in the support frame 2 always provides an upward elastic force, pushing the bearing seat 509 to drive the rotating shaft 511 and the second grinding roller 512 to fit tightly against the surface of the raw material 4, completing the high-precision grinding of the entire area of ​​the raw material 4; The third motor 10 drives the drive wheel 7 to rotate, and together with the fourth sprocket 11 and the second chain 12, the two drive wheels 7 rotate synchronously, replacing the manual pushing of the raw material 4, greatly reducing the labor intensity of the workers. At the same time, the drive wheel 7 and the driven wheel 3 work together to ensure the stability of the conveying path of the raw material 4 and avoid the deviation of the raw material 4 caused by manual operation. The first motor 504 drives the positive and negative lead screws 505 to rotate. Under the limit of the guide rod 502, the slider 503 moves synchronously in the opposite direction. The distance between the two sets of first grinding rollers 507 can be quickly adjusted to accurately adapt to raw materials 4 of different widths. The grinding needs of the front and back sides of stator plates of various specifications can be met without changing the grinding parts, thus improving the adaptability of the device and the grinding efficiency. The driven wheel 3 is driven to rotate by the conveying of raw material 4, and the second grinding roller 512 is rotated by the first sprocket 513, the second sprocket 514, the third sprocket 516 and the first chain 517. There is no need to set up an additional power source for the second grinding roller 512, which reduces the energy consumption of the device. The spring 510 provides continuous contact pressure to the second grinding roller 512 through the movable rod 508 and the bearing seat 509. Even if there are slight unevenness on the surface of the raw material 4, the spring 510 can adapt and adjust itself through elastic deformation to ensure that the second grinding roller 512 is always in close contact with the raw material 4, avoiding grinding omissions or over-grinding caused by the undulations of the raw material 4 surface, and ensuring the grinding accuracy of the raw material 4 surface.

[0018] The working principle of a grinding device for processing motor stator laminations: In use, the user first places the raw material 4 onto the driven wheel 3. When the raw material 4 is inserted into the driven wheel 3, the lower end of the raw material 4 will push the second grinding roller 512 to move downward. Then, the second grinding roller 512 drives the rotating shaft 511 to move, causing the rotating shaft 511 to drive the bearing seat 509 and the movable rod 508 to move downward, and compress the spring 510. Through the push of the spring 510, the second grinding roller 512 is kept in contact with the raw material 4. At the same time, the rotating shaft 511 will also drive the third sprocket 516 to move. Then, the second sprocket 514 is used to compensate the first chain 517 when the third sprocket 516 moves up and down, ensuring that the first sprocket 513, the second sprocket 514 and the third sprocket 516 can always be in transmission. Then, the hydraulic cylinder 9 installed on the bracket 8 is activated. The output end of the hydraulic cylinder 9 pushes the placement frame 6 to move down until the drive wheel 7 inside the placement frame 6 is in contact with the upper end of the raw material 4 to complete the positioning of the raw material 4. Then, the first motor 504 is activated. The output end of the first motor 504 drives the positive and negative lead screws 505 inside the slide groove 501 to rotate. Under the limiting action of the guide rods 502 at both ends of the slide groove 501, the two sliders 503 move closer or further away from each other along the slide groove 501 in sync, and finally the sliders 503 drive the first grinding roller 507 to contact the front and rear sides of the raw material 4. After the raw material 4 is installed and the position of the first polishing roller 507 is adjusted, the user can start the third motor 10. The output end of the third motor 10 drives one of the drive wheels 7 to rotate. The fourth sprocket 11 on the outer side of the front end of the drive wheel 7 drives the other drive wheel 7 to rotate synchronously through the second chain 12. When the drive wheel 7 controls the raw material 4 to rotate, the raw material 4 will also drive the driven wheel 3 to rotate passively, assisting the raw material 4 to rotate. Then, the second motor 506 is started, and the second motor 506 drives the first polishing roller 507 to rotate, so as to achieve the polishing work on the front and rear sides of the raw material 4. Then, when the driven wheel 3 assists the raw material 4 to rotate, the first sprocket 513 of the rod at the rear end of the driven wheel 3, through the first chain 517, cooperates with the second sprocket 514 at the front end of the connecting rod 515 on the rear side of the support frame 2 to drive the third sprocket 516 at the rear end of the rotating shaft 511 to rotate, thereby causing the second grinding roller 512 on the outer side of the rotating shaft 511 to rotate synchronously and grind the surface of the raw material 4. During this process, the spring 510 on the outer side of the movable rod 508 on the lower surface of the bearing seat 509 inside the support frame 2 always provides an upward elastic force, pushing the bearing seat 509 to drive the rotating shaft 511 and the second grinding roller 512 to fit tightly against the surface of the raw material 4, completing the high-precision grinding of the entire area of ​​the raw material 4.

[0019] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
