Description

Technical Field

[0001] This utility model relates to the field of stator processing technology, and in particular to a device for expanding holes in a motor stator. Background Technology

[0002] The stator of a motor is the stationary part of the motor or generator. Its main function is to generate a rotating magnetic field, while the rotating part (rotor) of the stator mainly functions to generate (output) current by being cut by magnetic lines of force in the rotating magnetic field. During the stator manufacturing process, the inner diameter of the metal cylinder is often smaller than the required inner diameter. To ensure subsequent machining accuracy and meet design requirements, its inner diameter needs to be enlarged, i.e., a hole reaming operation is performed.

[0003] The process of expanding the stator hole requires manual operation of multiple steps. This method not only hinders production speed but also increases the labor intensity of workers. In the process of expanding the stator inner ring, mechanical extrusion is often used, which can easily affect the stator slots. Currently, there is a need for a hole-expanding device that can protect the stator slots. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for expanding the hole in a motor stator.

[0029] As a technical optimization of this utility model, the fixing mechanism includes a first fixed plate 5 and movable plates 10. An electric telescopic rod 4 is installed on the side of the movable slider 3 away from the annular guide rail 2. The telescopic end of the electric telescopic rod 4 is away from the annular guide rail 2 and is connected to the first fixed plate 5. Multiple movable plates 10 are evenly and movably installed on the side of the first fixed plate 5 away from the electric telescopic rod 4. The extension and retraction of the electric telescopic rod 4 can drive the first fixed plate 5 to move according to different operational requirements.

[0030] As a technical optimization of this utility model, the second fixed plate 6 has a plurality of first sliding grooves 8 evenly distributed on the side away from the electric telescopic rod 4. The movable plate 10 is equipped with a first electric slider 9 at the end near the first sliding groove 8, and the first electric slider 9 is slidably installed inside the first sliding groove 8. By sliding the first electric slider 9 in the first sliding groove 8, the movable plate 10 can be moved on the second fixed plate 6, thereby completing the clamping and fixing of the stator.

[0031] As an optimized technical solution of this utility model, the hole-expanding mechanism includes an extrusion plate 26, a stabilizing rod 18, and a rotating rod 19. A rotary motor 21 is embedded in the second fixed plate 6 on the side near the annular guide rail 2. The output end of the rotary motor 21 is away from the second fixed plate 6, and the rotating rod 19 is installed at the output end of the rotary motor 21. Multiple extrusion plates 26 are evenly arranged along the circumference of the rotating rod 19 on its outer side. A fixing ring 17 is installed on the side of the second fixed plate 6 near the annular guide rail 2, and multiple stabilizing rods 18 are evenly installed on the side of the fixing ring 17 away from the second fixed plate 6. The rotary motor 21 can drive the rotating rod 19 to rotate, so that the device can expand the holes in the inner ring of the stator at different positions. The expansion of the inner ring of the stator can be completed by the extrusion plate 26 extruding the inner ring of the stator. During the hole-expanding process, the stabilizing rod 18 is inserted into the stator slot to provide auxiliary fixation for the stator slot and prevent damage to the stator slot during the hole-expanding process.

[0032] As a technical optimization of this utility model, a plurality of electric extension rods 20 are evenly installed on the side of the extrusion plate 26 near the rotating rod 19. The mounting ends of the electric extension rods 20 are away from the extrusion plate 26, and the mounting ends of the electric extension rods 20 are connected to the rotating rod 19. The electric extension rods 20 can drive the extrusion plate 26 to extend.

[0033] As a technical optimization of this utility model, a moving groove 23 is provided on the side of the extrusion plate 26 away from the rotating rod 19. A grinding plate 22 is provided inside the moving groove 23. Second sliding grooves 24 are provided on the inner walls of both ends of the moving groove 23. A second electric slider 25 is installed on the end of the grinding plate 22 facing the second sliding groove 24. The second electric slider 25 is slidably installed inside the second sliding groove 24. By sliding the second electric slider 25 in the second sliding groove 24, the grinding plate 22 can be moved out of the moving groove 23. Combined with the rotation of the rotating rod 19, the inner wall of the stator can be ground after the hole expansion is completed, thereby improving the production quality of the device.

[0034] As a technical optimization of this utility model, the cleaning mechanism includes a cleaning block 12 and a brush 13. A connecting rod 11 is installed on the side of the third fixing plate 7 facing the annular guide rail 2, and a cleaning block 12 is installed on the end of the connecting rod 11 facing the annular guide rail 2. An air groove 14 is opened inside the cleaning block 12, and multiple first openings 15 are evenly opened around the outer edge of the cleaning block 12. Multiple second openings 16 are evenly opened on the side of the cleaning block 12 facing the third fixing plate 7, and a brush 13 is installed on the side of the cleaning block 12 away from the third fixing plate 7. At this time, the cleaning block 12 and the brush 13 extend into the interior of the stator. During the movement, the brush 13 can brush off the iron filings that fall off the inner ring of the stator. The vacuum cleaner connected to the second opening 16 is activated, and the iron filings inside the stator can be removed through the first opening 15, increasing the ease of use of the device.

[0035] In use, all electrical devices in this device are powered via external power supplies connected by wires. The device controls these devices through a control system. The second opening 16 connects to a pre-installed industrial vacuum cleaner outside the device via a conduit. Industrial vacuum cleaners are existing, mature technology, and will not be described in detail here. The fixing ring 17 is bolted to the second fixing plate 6. The fixing ring 17 comes in various specifications, each with a different stabilizer bar 18. When dealing with different motor stators, different models of fixing rings 17 can be used to adjust the stabilizer bars 18 for different motor stators. The motor stator slots are protected. A rotating motor is installed at the connection between the electric telescopic rod 4 and the first fixed plate 5, which can drive the first fixed plate 5 to rotate. A camera is installed on the side of the second fixed plate 6 facing the annular guide rail 2. When the stator slot of the stator installed on the first fixed plate 5 needs to be inserted and installed with the stabilizer rod 18, the camera takes a picture of the stator. The background control system determines the position of the stator and controls the rotating motor to drive the first fixed plate 5 to rotate, so that the stator slot can be aligned with the position of the stabilizer rod 18. This facilitates the smooth insertion of the stator slot into the stabilizer rod 18 and increases the stability of the device's function.

[0036] When it is necessary to enlarge the hole of the motor stator, the movable slider 3 slides in the annular guide rail 2, so that the first fixed plate 5 moves to the preset position. At this time, the worker places the motor stator between the multiple movable plates 10 on the first fixed plate 5. Then, by sliding the first electric slider 9 in the first slide groove 8, the multiple movable plates 10 move closer to each other, so that the movable plates 10 complete the clamping and fixing of the motor stator.

[0037] After the motor stator is fixed, the sliding slider 3 moves the first fixing plate 5, on which the motor stator is fixed, to a preset position on the second fixing plate 6. Then, the electric telescopic rod 4 drives the first fixing plate 5 to move toward the second fixing plate 6 until the inner ring of the motor stator is fitted onto the outside of the extrusion plate 26. The stabilizing rod 18 is inserted into the wire groove of the stator. The electric extension rod 20 drives the extrusion plate 26 to move away from the rotating rod 19. During the movement of the extrusion plate 26, the inner ring of the stator can be extruded and enlarged by the extrusion plate 26 extruding the inner ring of the stator. By rotating the rotating rod 19, the device can enlarge the inner ring of the stator at different positions, thus completing the initial enlargement work of the inner ring of the stator.

[0038] During the hole enlargement process, the stabilizing rod 18 is inserted into the stator slot to provide auxiliary fixation for the stator slot, preventing damage to the stator slot during hole enlargement and increasing the ease of use of the device. After the stator hole enlargement is completed, the second electric slider 25 slides in the second slide groove 24, allowing the grinding plate 22 to extend out of the preset position inside the moving groove 23 and be adjusted to abut against the inner ring of the stator. Then, by rotating the rotating rod 19, the inner ring of the stator can be ground, completing the final hole enlargement work of the stator and improving the processing quality of the stator by the device.

[0039] After the stator is enlarged and polished, the electric telescopic rod 4 drives the first fixed plate 5 to retract, causing the stator to detach from the extrusion plate 26. Then, the first fixed plate 5 moves to the preset position of the third fixed plate 7. The electric telescopic rod 4 drives the first fixed plate 5 to move towards the third fixed plate 7. At this time, the cleaning block 12 and the brush 13 can extend into the interior of the stator. During the movement, the brush 13 can brush off the iron filings that fall off the inner ring of the stator during polishing. The vacuum cleaner connected to the second opening 16 is started. Through the first opening 15, the iron filings inside the stator can be removed, increasing the ease of use of the device. After cleaning, the first fixed plate 5 moves away from the third fixed plate 7 and moves to the preset position under the drive of the moving slider 3. Then, the multiple movable plates 10 move away from each other and no longer fix the stator. At this time, the operator unloads the stator. The loading and unloading of the stator in this device can be done manually or automatically by a preset robotic arm.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
