[0045] The motor stator winding slot wedge auxiliary installation device of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0046] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0047] This embodiment discloses a motor stator winding slot wedge auxiliary installation device, which can realize automatic loading, slot wedge installation and unloading of stator winding through a mechanical structure, reducing the labor intensity of workers, and at the same time ensuring the slot wedge installation quality and installation accuracy through the mechanical structure. Figure 1 , which mainly includes a frame part 1, a limiting feeding part 2, a matching drive part 3 and a slot wedge feeding unit 4. The limiting feeding part 2 is arranged in the middle of the frame part 1. The matching drive part 3 is arranged on both sides of the frame part 1. At the same time, the main body of the matching drive part 3 is located above the limiting feeding part 2. The slot wedge feeding unit 4 is arranged on the side of the matching drive part 3. The frame part 1 is used to support the limiting feeding part 2 and the matching drive part 3, and at the same time transport the stator winding 5. The limiting feeding part 2 can deliver the stator winding 5 to the matching drive part 3, and the stator winding 5 is driven by the matching drive part 3 to rotate. The stator winding 5 rotates and the slot wedge is inserted by the slot wedge insertion unit 4. See the following for details.

[0048] To accommodate the limited feeding part, cooperate with the driving part, and transmit the stator winding, see Figure 1 The frame portion 1 includes a base frame 101, legs 102, and a top frame 103. The base frame 101 is supported and connected to the top frame 103 via the legs 102. The top frame 103 is arranged in an inclined shape, and the limited feeding portion 2 is arranged in the middle of the base frame 101. The mating drive portion 3 is fixedly connected to the outer side of the top frame 103.

[0049] Through the above structure, the inclined top frame 103 can make the stator winding 5 placed thereon roll from one end to the other end, thereby completing the transmission of the stator winding 5.

[0050] In this embodiment, the base frame 101 is made of I-shaped steel to ensure support strength. Figure 3 A receiving plate 111 is provided in the middle of the inner side of the base frame 101 . The receiving plate 111 is used to receive the position-limiting feeding part 2 , and the lifting support rod 201 is fixedly provided on the receiving plate 111 .

[0051] In order to ensure the stability of the stator winding during transmission, in actual implementation, the top frame 103 includes two symmetrically arranged L-shaped limiting rails 131. Figure 3 、 Figure 4 The L-shaped limiting rails 131 are connected by an H-shaped reinforcement frame 132. The spacing between the two symmetrically arranged L-shaped limiting rails 131 matches the stator width of the stator winding 5. The H-shaped reinforcement frame 132 ensures the strength of the L-shaped limiting rails 131 and prevents the stator winding 5 from sliding out of the L-shaped limiting rails 131 during rolling, ensuring stability during stator winding 5 transportation.

[0052] To ensure that the stator winding is delivered to the mating drive during transport, see Figure 1 The limited feeding section 2 includes a lifting rod 201 and a support platform 202. The bottom end of the lifting rod 201 is mounted on the receiving plate 111. The support platform 202 is mounted on the top end of the lifting rod 201. The specifications of the support platform 202 are compatible with the specifications of the stator winding 5. With this structure, the lifting rod 201 can be raised and lowered via the support platform 202 to lift or lower the stator winding 5 from the top frame 103.

[0053] Specifically, in order to achieve the stator winding stably supported by the support 202, see Figure 1 、 Figure 3 , the support platform 202 includes a U-shaped support plate 221, a roller group 222 and a reinforcing rib A223. The U-shaped support plate 221 is fixedly arranged on the top of the lifting support rod 201. The roller group 222 is arranged inside the U-shaped support plate 221. The reinforcing rib A223 is symmetrically arranged on the top inner side of the U-shaped support plate 221. An arc-shaped bracket 226 is opened on the top of the U-shaped support plate 221. In this embodiment, the specifications of the arc-shaped bracket 226 are adapted to the curvature of the outer surface of the stator winding 5. The roller group 222 is arranged inside the U-shaped support plate 221 at the arc-shaped bracket 226. Through the above structure, the arc-shaped bracket 226 cooperates with the roller group 222, and under the action of the lifting support rod 201, the stator winding 5 on the top frame is stably lifted.

[0054] See also Figure 1 、 Figure 3 In this embodiment, a sensor probe 224 is further disposed within the U-shaped support plate 221 below the arc-shaped bracket 226. The sensor probe 224 is disposed within the U-shaped support plate 221 via a probe bracket 225. The sensor probe 224 can sense the position of the stator winding 5, thereby controlling the operating time of the lifting support rod 201.

[0055] In order to realize that after the stator winding is sent to the matching drive part by the limited feeding part, the matching drive part drives the stator winding to rotate, see Figure 1 、 Figure 2The mating drive unit 3 includes a mounting frame 301 and a positioning drive frame 302. The mounting frame 301 is symmetrically arranged on the side of the top frame 103. The positioning drive frame 302 is arranged above the support 202 through the mounting frame 301. The positioning drive frame 302 is adapted to the specifications of the stator winding 5. The slot wedge feeding unit 4 is arranged on the mounting frame 301 on one side of the positioning drive frame 302. The positioning drive frame 302 can be limited and installed through the mounting frame 301. The positioning drive frame 302 can position the stator winding 5 and drive it. See the following for details.

[0056] To realize positioning of the positioning drive frame 302, see Figure 2 、 Figure 3 The mounting frame 301 is symmetrically arranged on both sides of the top frame 103. The bottom of the mounting frame 301 is fixedly connected to the top frame 103. The inner side of the top is connected to the positioning drive frame 302 through a compensation block 311. The above structure can ensure the stability of the positioning drive frame 302 during operation.

[0057] To drive the stator winding, see Figure 1 、 Figure 2 The positioning drive frame 302 includes a limit plate 321, a drive motor 322 and a drive roller 323. The limit plate 321 is symmetrically arranged on the inner side of the mounting frame 301. The limit plate 321 is used to limit the position of the stator winding 5. In order to ensure the strength of the limit plate 321, reinforcing ribs B324 are provided between the limit plates 321. The drive motor 322 is arranged on the inner side of the limit plate 321, and the output end of the drive motor 322 is driven and connected to the drive roller 323. The drive motor 322 can drive the drive roller 323 to operate, and the operation of the drive roller 323 can also drive the stator winding 5 to rotate.

[0058] To achieve the limit plate to limit the stator winding, see Figure 5 The inner side of the limiting plate 321 corresponding to the edge of the stator winding 5 has an arc-shaped limiting groove 325. The arc-shaped limiting groove 325 matches the curvature of the edge of the stator winding 5. The driving roller 323 is disposed on the inner side of the limiting plate 321 at the arc-shaped limiting groove 325. The arc-shaped limiting groove 325 limits the stator winding 5 to prevent lateral displacement.

[0059] In this embodiment, the drive motor 322 is a dual-shaft reduction motor. The output shaft of the drive motor 322 passes through a stop plate 321 and is provided with a drive wheel 326 at each end. The rotating shaft of the drive roller 323 passes through the stop plate 321 and is provided with a driven wheel 327. The drive wheel 326 is connected to the driven wheel 327 via a transmission belt 328.

[0060] It should be noted that, in specific implementation, the transmission structure of the above-mentioned driving wheel 326, driven wheel 327 and transmission belt 328 can be equivalently replaced by a chain transmission structure, a gear transmission structure and an axis transmission structure, etc., as long as the structure can realize the driving motor to drive the driving roller 323.

[0061] In addition, in order to prevent the driving roller from slipping when driving the stator winding to rotate, an anti-slip sleeve is provided on the outside of the driving roller 323.

[0062] To insert the slot wedges after the stator winding is in place, see Figure 2 、 Figure 6 The slot wedge feeding unit 4 includes a feeding roller assembly 401 and a feeding motor 402. The feeding roller assembly 401 is mounted on the mounting frame 301. The feeding motor 402 is connected to the feeding roller assembly 401 via a transmission gear assembly 403 and a transmission chain 404. With this structure, the feeding motor 402 drives the feeding roller assembly 401, which in turn drives the slot wedges to be inserted into the stator windings.

[0063] For details, see Figure 6 In this embodiment, the feed roller assembly 401 includes a limiting roller 411 and a positioning roller 412. The limiting roller 411 and positioning roller 412 are mounted on the mounting frame 301 via a roller frame. To ensure accurate wedge feeding, in this embodiment, the positioning roller 412 is a profiled roller with an annular groove in the middle that matches the wedge's external dimensions. This profiled roller limits the wedge's position, thereby ensuring accurate wedge feeding. The feed motor 402 drives and connects to the positioning roller 412 and / or limiting roller 411.

[0064] The working principle of the motor stator winding slot wedge auxiliary installation device of the utility model is as follows:

[0065] When this device is in use, the stator winding is placed on the inclined top frame, and the stator winding rolls along the inclined top frame. After rolling to the support platform of the limited feeding part, the sensor probe at the support platform senses the stator winding and the lifting support rod runs. The operation of the lifting support rod drives the support platform to rise, and the support platform lifts the sensed stator winding to the positioning drive frame. At the same time, the support platform rises to intercept the next stator winding.

[0066] When the support platform lifts the stator winding to the positioning drive frame, the positioning drive frame cooperates with the support platform to limit the position of the stator winding. After the stator winding position is limited, the drive motor is started, and the drive motor drives the drive roller to run, and the drive roller drives the stator winding to rotate. When the slot of the stator winding corresponds to the slot wedge feeding unit, the feeding motor drives the feeding roller group to run, and the feeding roller group runs to feed the slot wedge into the slot of the stator winding, thereby completing the slot wedge insertion.

[0067] It should be noted that, during the specific implementation of this device, the structures depicted in the drawings of this specification are not fixed, unchanging implementations. For example, the transmission structure of the drive wheel 326, driven wheel 327, and transmission belt 328 can be replaced with a chain drive structure, a gear drive structure, a shaft drive structure, etc., as long as the drive motor 322 can drive the drive roller 323. Furthermore, during actual implementation, the tilt angle of the top frame and the number of slot wedge feed units can be adjusted according to actual needs. Furthermore, the drawings of this specification and the abstract are schematic diagrams only and do not represent the specific structure or actual number of units in a specific implementation.
