Description

Technical Field

[0001] The present application relates to the technical field of motor assembly, and in particular to a winding stator core embedding device for a central high H355-H630 high voltage motor. Background Art

[0002] The center height H355-H630 high-voltage motor refers to a high-voltage motor whose vertical distance from the axis to the plane of the motor base ranges from 355 mm to 630 mm. It is mainly used in industrial fields, such as driving water pumps, fans, compressors and other equipment. During the motor manufacturing process, the stator coil needs to be embedded in the stator wire slots of the motor to form the stator winding of the motor. Wire embedding is a very important link in the motor winding rewinding process, and it is also a meticulous job. At present, the stator wire embedding of existing medium and large motors is basically completed on the ground or on a steel structure platform. In order to facilitate the workers to operate the embedding operation, the motor stator wire embedding position must always be kept in the area under the operator's hand that can be touched, which needs to be achieved by flipping the motor stator along the center axis. Reference Figure 1 There are stator ribs 101 on the outer diameter of the stator of the center high H355-H630 high-voltage motor. The stator core 100 is heavy. It is difficult to manually turn it over and carry it during wire embedding. The production efficiency is low and the labor intensity is high. Moreover, it is easy to cause the insulation of the formed coil to be damaged during wire embedding, which affects the electrical performance of the motor.

[0003] For related technologies, please refer to the Chinese patent with the announcement number CN207753586U, which discloses a motor stator winding wire embedding tool. The tool includes a support seat and a rotating frame for installing the motor stator. The support seat includes two vertically arranged and detachably connected support plates. Two rolling bearings are arranged on each support plate. The rotating frame is located between the two support plates, and the rotating frame is rotatably supported on the rolling bearings. Two latch holes are also arranged on each support plate. The two latch holes are located on the outside of the rolling bearings, and each latch hole is provided with a pluggable limit latch. When in use, the motor stator is first installed on the rotating frame, and the rotating frame is rotated on the rolling bearings on the support seat by external force. After the rotating frame rotates to the right position, the limit latch is inserted and pulled out in the latch hole to complete the temporary fixation of the rotating frame. At this time, the winding embedding work of the motor stator can be carried out.

[0004] With regard to the above-mentioned related technologies, the relative distance between the two support plates is fixed and can only be used to embed stator cores of the same length. At the same time, the distance between the two rolling bearing axes is also fixed. When the outer diameter of the stator core is large, during the placement or rotation of the stator core, the stator core is prone to eccentricity due to its own gravity and fall from the rolling bearing, thereby causing quality problems.

[0046] Reference Figure 2 One end of the driving shaft 212 is connected to a driving device 25, and the driving device 25 is located on the side of the support seat 2 close to the first locking block 132. The rotating ring 24 provided on the first supporting wheel 211 and the second supporting wheel 221 is adapted to the stator rib 101 on the outer wall of the stator core 100. The driving device 25 drives the first supporting wheel 211 to rotate through the driving shaft 212, thereby driving the rotating ring 24 to rotate, and then driving the stator core 100 to rotate, thereby reducing manual handling and flipping, reducing labor intensity, and improving wire insertion efficiency.

[0047] Reference Figure 6 and Figure 7 The driving device 25 includes a rotating rod 253, a chain 254, a first sprocket 255, a second sprocket 256, a handle link 251 and a handle grip 252. One end of the rotating rod 253 is rotatably connected to the first support frame 21. The axial directions of the rotating rod 253 and the driving shaft 212 are parallel to each other. One end of the handle link 251 is fixedly connected to the handle grip 252. The end of the handle link 251 away from the handle grip 252 is fixedly connected to the rotating rod 253. The handle grip 252 is located on a side of the handle link 251 away from the first support frame 21. The driving shaft 212 is coaxially fixedly connected to the first sprocket 255. The rotating rod 253 is coaxially fixedly connected to the second sprocket 256. The first sprocket 255 and the second sprocket 256 are both meshed with the chain 254. A positioning rod 26 is inserted into the handle link 251, and the positioning rod 26 is located between the handle grip 252 and the rotating rod 253. The axial direction of the positioning rod 26 is parallel to the axial direction of the driving shaft 212. A plurality of positioning holes 214 are provided on the first support frame 21, and the plurality of positioning holes 214 are evenly arranged along the circumference of the first support wheel 211. The arrangement of the positioning rod 26 allows the handle link 251 to be locked at different angles, so that the handle position can be adjusted according to actual needs, thereby improving the convenience of operation and the efficiency of thread insertion.

[0048] Reference Figure 7A retaining ring 261 is fixedly disposed on the outer wall of the positioning rod 26 , and the retaining ring 261 is located between the handle connecting rod 251 and the first support frame 21 . An elastic member 262 is disposed between the retaining ring 261 and the handle connecting rod 251 , and the elastic member 262 can be a spring. The spring 262 is sleeved on the outer wall of the positioning rod 26, and a limit block 263 is fixedly provided at the end of the positioning rod 26 away from the first support frame 21. The outer diameter of the limit block 263 is larger than the outer diameter of the positioning rod 26. When the spring 262 is in a natural state, one end of the positioning rod 26 is inserted into the positioning hole 214 and the end of the limit block 263 close to the first support frame 21 abuts against the end of the handle connecting rod 251 away from the first support frame 21 to prevent the positioning rod 26 from axial movement during use. At the same time, the positioning rod 26 and the first support frame 21 can be quickly positioned when the handle 252 is rotated; the setting of the limit block 263 is used to limit the positioning rod 26 to prevent the positioning rod 26 from falling from the side of the handle connecting rod 251 close to the first support frame 21, thereby ensuring the position stability of the positioning rod 26 when it is inserted into the positioning hole 214, ensuring the reliable fixation of the handle connecting rod 251 at different angles, and improving the stability of the equipment and the convenience of operation during the wiring process.

[0049] When the stator core 100 needs to be rotated, the staff pulls the limit block 263 to pull the positioning rod 26 out of the first support frame 21, and then the staff holds the handle 252 and rotates it. The handle connecting rod 251 rotates to drive the rotating rod 253 to rotate, and then drives the driving shaft 212 to rotate through the first sprocket 255, the second sprocket 256 and the chain 254. After rotating a certain angle, the positioning rod 26 is inserted into the positioning hole 214 under the action of the elastic member 262, so that the first support wheel 211 does not rotate, thereby preventing the stator core 100 from rotating, and preventing accidents and quality problems caused by the rotation of the stator core 100 during the wire embedding process.

[0050] The implementation principle of the stator core wire embedding device for a high-voltage motor with windings of H355-H630 in the embodiment of the present application is as follows: the stator core wire embedding device for a high-voltage motor with windings of H355-H630 in the embodiment of the present application can realize the rapid adjustment and positioning of the stator core 100. The two support seats 2 on the workbench 1 can slide in opposite directions along the axial direction thereof through the first bidirectional lead screw 11, thereby adapting to the wire embedding requirements of the stator core 100 with different lengths along the axial direction, thereby improving the adaptability of the device. The first support frame 21 and the second support frame 22 slide in opposite directions along their axis through the second bidirectional lead screw 23, so that the first support wheel 211 and the second support wheel 221 can accurately adjust the spacing to adapt to stator cores 100 of different diameters, improve the adaptability of the equipment, ensure the stable support of the stator core 100 during the wire embedding process, and ensure that the stator core 100 does not deviate when it is placed on the first support wheel 211 and the second support wheel 221 and rotates, reducing the phenomenon of the stator core 100 falling due to eccentricity caused by its own gravity during the rotation process, and reducing the quality problems caused by falling. The rotating ring 24 set on the first support wheel 211 and the second support wheel 221 is adapted to the stator rib 101 on the outer wall of the stator core 100, and the driving device 25 drives the first support wheel 211 to rotate through the driving shaft 212, thereby driving the rotating ring 24 to rotate, and then driving the stator core 100 to rotate, reducing manual handling and flipping, reducing labor intensity, and improving wire embedding efficiency.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
