Description

Technical Field

[0001] This application relates to the technical field of auxiliary equipment for motor production, and in particular to a device for quickly grinding the ends of motor rotors during production. Background Art

[0002] The motor rotor is an essential basic component of synchronous or asynchronous motors. In the actual motor production process, many different production processes are used. In some existing drive components, metal copper bars are inserted equidistantly into the rotor to enhance the heat dissipation, stability, or power of the rotor. During the manufacturing of such rotors, after inserting the copper bars, the ends of the rotor need to be welded. After welding, there are uneven parts such as welding slag on the planes at both ends of the rotor. Therefore, it is necessary to grind the ends of the welded rotor. In the existing grinding devices, there is no special grinding equipment for this type of motor rotor. It is necessary to manually hold a grinding machine or hold the rotor to grind the ends. This form is slow in grinding speed on the one hand, and uneven in grinding quality on the other hand. In order to achieve better grinding quality, more time needs to be consumed in grinding, which will affect the motor performance to a certain extent and reduce the production efficiency. Therefore, it is necessary to improve the existing grinding equipment to solve these problems in grinding. Summary of the Invention

Detailed Embodiments

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] To more clearly understand the technical solutions shown in the embodiments of the present application, the working principle of the existing end grinding for the production of motor rotors will be introduced first.

[0022] After the existing motor rotors are welded, there are raised parts such as metal slag at the ends. It is necessary to manually hold the rotor and make its end contact with the grinding machine to achieve grinding. For some larger rotors, due to their own weight, they can only be placed on the ground or other supporting planes, and then hold the grinding tool to grind. There are certain safety hazards in this operation process, and for the hand-held grinding method, the grinding quality is mostly based on the experience of the workers, and the quality is uneven. Therefore, a special grinding device needs to be set up to solve these problems.

The movable rod 2 is vertically slidably connected to a position near the middle of the connecting plate 1. The connecting seat 3 is fixedly connected to the upper end of the movable rod 2. A chute is provided in the middle of the connecting seat 3. The slide bar 4 is slidably connected in the chute of the connecting seat 3. Tooth grooves are equidistantly provided on the upper surface of the slide bar 4. The connecting arm 5 is L-shaped in appearance. One side of the connecting arm 5 is fixedly connected to the side surface of the connecting seat 3. The bent end of the connecting arm 5 corresponds to the right end of the slide bar 4. The rotor body of the motor is connected between the slide bar 4 and the bent end of the connecting arm 5. The toothed shaft 6 is rotatably connected to a position above the right end of the slide bar 4. The toothed shaft 6 is meshed and connected to the tooth groove at the upper end of the slide bar 4. The servo motor 7 is fixedly connected to the surface of one side of the toothed shaft 6. The output shaft of the servo motor 7 is fixedly connected to one end of the toothed shaft 6. The rotating shaft 8 is rotatably connected to a position slightly to the right of the middle of the connecting plate 1. The connecting disc 9 is fixedly connected to the upper end of the rotating shaft 8. The grinding disc 10 is cooperatively connected to the upper surface of the connecting disc 9. The spiral spring 11 is sleeved outside the corresponding movable rod 2 between the lower surface of the connecting seat 3 and the upper surface of the connecting plate 1. The driving motor 12 is provided on the lower surface of the right end of the connecting plate 1. The driven disc 13 is fixedly connected to the lower end of the rotating shaft 8. The end of the output shaft of the driving motor 12 is in transmission connection with the driven disc 13 through the transmission belt 14. One end of the connecting rod 15 is fixedly connected to the lower end of the movable rod 2. The vertical slide bar 16 is vertically slidably connected to a position near the middle of the left end of the connecting plate 1. The lower end of the vertical slide bar 16 is fixedly connected to the connecting rod 15. The connecting rod 17 is fixedly connected to the rear side surface of the connecting plate 1 near the left end. One end of the pressing rod 18 is movably connected to the connecting rod 17. The lower surface of the pressing rod 18 is cooperatively connected to the upper end of the vertical slide bar 16. The limiting block 19 is fixedly connected to the middle position of the left end of the connecting plate 1. The guiding rod 20 is vertically slidably connected in the limiting block 19. The lower end of the guiding rod 20 is fixedly connected to the other end of the connecting rod 15.

[0024] Specifically, the provided connecting plate 1 is used to provide a position for connection and support for the installation of components.

At this time, the lower end of the rotor body approaches the grinding disk 10, so as to realize grinding.

[0032] Specifically, the setting of the handle 24 is convenient for holding, enabling personnel to complete the operation with less force applied at the holding position, and at the same time avoiding problems such as pinching caused by personnel operating other positions, ensuring safety during use.
