Description

Technical Field

[0001] This invention relates to the field of stator coil finishing technology, and in particular to a finishing device for winding coils used in main pumps. Background Technology

[0002] The manufacturing process of motor stator coils involves a systematic forming process: First, after the coil winding is completed, an initial shaping operation is performed, and the coil outline is initially corrected using special tooling; then, a rolling process is used to radially compact the coil to ensure the density of the conductor arrangement; finally, a finishing process is performed before final assembly. This process must strictly ensure that the inner diameter of the coil and the outer profile of the rotor maintain the design gap (usually requiring a single-sided gap of ≥0.5mm between the inner wall of the coil and the outer wall of the rotor), while controlling the assembly tolerance between the outer diameter of the coil and the inner diameter of the housing (ensuring a single-sided gap of ≤0.3mm between the outer wall of the coil and the inner wall of the housing).

[0003] Traditional finishing equipment has significant drawbacks: to adapt to the production needs of motors of various specifications, the equipment requires multiple sets of molds, which not only leads to complex mold inventory management and time-consuming tooling changeovers (an average of 45 minutes per mold change), but also results in high mold processing costs (the cost of a single precision mold is approximately 80,000-120,000 yuan). To address these pain points, this invention proposes a solution. Summary of the Invention

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Reference Figures 1-10 This embodiment of the invention provides a finishing device for winding coils of a main pump, capable of automatically adapting to finishing operations of various motor models. It includes a base assembly 100, a drive assembly 200 fixed to the base assembly 100, a positioning assembly 300 sliding in the middle of the drive assembly 200, a trigger assembly 400 sliding in the center of the positioning assembly 300, a measuring assembly 500 fixed to the bottom of the trigger assembly 400, an expansion assembly 600 fixed to the top of the trigger assembly 400, and a spring assembly 700 fixed inside the positioning assembly 300. A limiting component 800 is fixed at the center of the elastic component 700. The limiting component 800 is connected to the trigger component 400. A pressing component 900 is fixed at the bottom of the elastic component 700. The trigger component 400 can trigger the measuring component 500 to measure the inner wall of the stator and drive the expansion component 600 to fit and press the stator coil. The trigger component 400 can also drive the limiting component 800 to release the limiting of the elastic component 700. Thus, the elastic component 700 can drive the pressing component 900 to press the outer wall of the stator coil. It has the function of automatically adapting to various stator coil finishing operations.

[0037] Specifically, such as Figure 4 In the process, the base support assembly 100 includes a worktable 101, a support platform 102 fixed to the top of the worktable 101, a positioning groove 103 at the front end of the support platform 102, a positioning plate 104 movably connected to the positioning groove 103, a base support 105 fixed to the top of the positioning plate 104, and an abutment block 106 fixed to the center of the interior of the base support 105. Since the abutment block 106 is the fundamental component that abuts the positioning assembly 300 and triggers the subsequent structure of the present invention, the abutment block 106 can be replaced along with the base support 105 when the stator height is different. In use, different base supports 105 can be used according to different motor models. Simply place the stator on the base support 105 and then align the positioning plate 104 with the positioning groove 103.

[0038] Furthermore, such as Figure 1 In the drive assembly 200, there are motors 201 fixed to the top of the support platform 102, pulleys 202 rotatably disposed at the center of the top of the support platform 102, the drive end of the motor 201 and the pulleys 202 connected by a belt, a movable tube 205 sliding on the inner wall of the pulleys 202, a telescopic rod 203 fixed to the inner wall of the bottom end of the support platform 102, the drive end of the telescopic rod 203 passing through the top of the support platform 102, a connecting rod 204 fixed to the drive end of the telescopic rod 203, and the connecting rod 204 connected to the trigger assembly 400. In use, the telescopic rod 203 can drive the connecting rod 204 and the trigger assembly 400 to move up and down, and the motor 201 can drive the pulleys 202 and the movable tubes 205 to rotate by a belt.

[0039] Furthermore, such as Figure 5 In the middle, the positioning component 300 includes a housing 301 fixed to the bottom of the drive component 200. The housing 301 is T-shaped. The top of the housing 301 is connected to the bottom of the movable tube 205 in the drive component 200. The bottom end of the housing 301 is provided with a first slide groove 302 and a second slide groove 303. There are four first slide grooves 302 and four second slide grooves 303 at the bottom of the housing 301. The first slide groove 302 is located on the inner side of the bottom of the housing 301, and the second slide groove 303 is located on the outer side of the bottom of the housing 301. A conical block 304 is fixed to the outer wall of the housing 301. The conical block 304 has the function of expanding the stator coil when the positioning component 300 is inserted into the stator, and also prevents the possibility of subsequent structures squeezing the coil. A trigger block 305 is rotatably set at the bottom of the housing 301.

[0040] Furthermore, such as Figure 5 In the middle, the trigger component 400 includes a central rod 401 that slides on the inner wall of the positioning component 300. The central rod 401 slides on the inner wall of the outer shell 301 of the positioning component 300. The top end of the central rod 401 is provided with a square groove 402. A transmission rod 403 slides in the square groove 402. A spring 404 is fixed at the bottom of the transmission rod 403 and located in the square groove 402. The transmission rod 403 is connected to the drive component 200. The transmission rod 403 is rotatably connected to the connecting rod 204 in the drive component 200. In use, the transmission rod 403 can drive the central rod 401 to move downward. When the central rod 401 cannot move, the spring 404 can be squeezed by the transmission rod 403.

[0041] Furthermore, such as Figure 6 In the measurement assembly 500, there are a first ring 501 fixed to the bottom of the central rod 401, a first push-pull rod 502 rotatably disposed on both sides of the first ring 501, a housing 301 having a reserved groove at the first push-pull rod 502 for moving the first push-pull rod 502, and a slide rod 503 rotatably disposed at the bottom of the first push-pull rod 502. The slide rod 503 is adapted to the positioning assembly 300. The two slide rods 503 slide on the T-shaped bottom of the housing 301 in the positioning assembly 300. A roller 504 is rotatably disposed on the outside of the slide rod 503. In use, when the central rod 401 drives the first ring 501 to move downward, it can drive the first push-pull rod 502 to drive the slide rod 503 to move outward. The slide rod 503 can drive the roller 504 to move to the inner wall of the stator, thereby forming the function of measuring the inner wall of the stator.

[0042] Furthermore, such as Figure 7In the middle, the expansion component 600 includes a second ring 601 fixed to the top of the central rod 401, four second push-pull rods 602 rotatably disposed around the second ring 601, and a first slider 603 rotatably disposed at the bottom of the second push-pull rods 602. The first slider 603 is adapted to the positioning component 300 and slides inside the positioning component 300. An expansion roller 604 is rotatably disposed at the bottom of the first slider 603. The overall outer position of the four expansion rollers 604 is larger than the overall outer position of the two rollers 504. In use, when the central rod 401 moves downward, the second push-pull rods 602 can drive the first slider 603 and the expansion rollers 604 to move outward. Since the central rod 401 synchronously drives the measuring component 500, the expansion rollers 604 can automatically expand to the stator coil, thereby automatically adapting to the stator coil and squeezing the inner side of the stator coil.

[0043] Furthermore, such as Figure 8 In the middle, the elastic component 700 includes a fixing ring 701 fixed to the inner wall of the positioning component 300, the fixing ring 701 being fixed inside the outer shell 301 of the positioning component 300, and a limiting ring 702 rotatably disposed on the outer wall of the fixing ring 701. The outer wall of the limiting ring 702 is provided with an arc-shaped edge 703, and four arc-shaped edges 703 are evenly distributed on the outer wall of the limiting ring 702. A connecting ring 704 is fixed to the top of the limiting ring 702, and a circular block 705 is disposed at the arc-shaped edge 703. The initial position of the circular block 705 is at the arc-shaped edge 703. On the outer side, an arc-shaped block 706 is fixed to the bottom of the circular block 705. An elastic band 707 is located inside the arc-shaped block 706. In use, rotating the connecting ring 704 can drive the limiting ring 702 to rotate. As a result, the circular block 705 located on the outer side of the arc-shaped edge 703 on the limiting ring 702 will be released from its limit. Thus, the elastic band 707 can drive the arc-shaped block 706, the circular block 705, and the pressing assembly 900 to move inward. Therefore, when the inner coil of the stator is finely trimmed, the fine work on the outer coil of the stator is also triggered.

[0044] Furthermore, such as Figure 9 , 10 In the middle, the limiting component 800 includes a circular tube 801 fixed to the center of the elastic component 700. The circular tube 801 is connected to the inner wall of the connecting ring 704 in the elastic component 700. The inner wall of the circular tube 801 is provided with a vertical groove 802 and an inclined groove 803. The vertical groove 802 and the inclined groove 803 are connected. A circular rod 804 slides in the vertical groove 802 and the inclined groove 803. The circular rod 804 is connected to the trigger component 400. The circular rod 804 is connected to the transmission rod 403 in the trigger component 400.

[0045] The extrusion assembly 900 includes a second slider 901 fixed to the bottom of the arc-shaped block 706. The second slider 901 is adapted to the positioning assembly 300. An extrusion roller 902 is rotatably disposed at the bottom of the second slider 901. In use, when the transmission rod 403 moves downward, it can drive the round rod 804 to move downward. Thus, the round rod 804 can move from the top of the vertical groove 802 to the bottom of the inclined groove 803, and then from the top of the inclined groove 803 to the bottom of the inclined groove 803. At this time, the movement relationship between the round rod 804 and the inclined groove 803 can cause the round tube 801 to rotate. The round tube 801 can drive the elastic assembly 700 to rotate. This can realize the delayed triggering of the elastic assembly 700 and the extrusion assembly 900. In use, the expansion assembly 600 can first expand the inner side of the stator coil, and then the extrusion assembly 900 can extrude the outer side of the stator coil.

[0046] In use, different base supports 105 can be used depending on the motor model. Simply place the stator on the base support 105, and then align the positioning plate 104 with the positioning groove 103. Then, the drive telescopic rod 203 drives the connecting rod 204, transmission rod 403, and subsequent structures to move downwards. When the trigger block 305 contacts the abutment block 106, the transmission rod 403 can continue to move downwards and compress the spring 404. The pressure of the spring 404 is applied to the center rod 401, causing the center rod 401 to move downwards. When the first ring 501 and the second ring 601 move downwards, the first ring 501 drives the first push-pull rod 502 to drive the two side slide rods 503 and rollers 504 to expand outwards until the rollers 504 are in contact with the inner wall of the stator. At the same time, the second ring 601 drives the second push-pull rod 602 to drive the first slider 603 to automatically expand outwards to the stator coil, thus realizing the function of automatically adapting to the coil finishing of various stators. Furthermore, when the central rod 401 moves downwards, it can drive the round rod 804 to move downwards. The round rod 804 can move from the top of the vertical groove 802 to the bottom of the inclined groove 803, and then from the top of the inclined groove 803 to the bottom of the inclined groove 803. At this time, the movement relationship between the round rod 804 and the inclined groove 803 can cause the round tube 801 to rotate. The round tube 801 can drive the connecting ring 704 and the limiting ring 702 to rotate. As a result, the round block 705 located on the outer side of the arc edge 703 on the limiting ring 702 will be released from its limiting position. Then, the elastic band 707 can drive the arc block 706, the round block 705, and the extrusion assembly 900 to move inward. The lateral movement triggers the fine finishing of the inner side of the stator coil, and after a delay of the vertical slot 802, it triggers the fine finishing of the outer side of the stator coil. At this time, the inner and outer sides of the stator coil can be automatically adapted. By starting the motor 201, the drive end of the motor 201 drives the pulley 202 to rotate through the belt. The pulley 202 can drive the movable tube 205, the outer shell 301 and subsequent structures to rotate. The rotating expansion component 600 and the extrusion component 900 can then fine the inner and outer sides of the stator coil.

[0047] In summary, the triggering component 400, measuring component 500, and expansion component 600 can automatically measure the inner wall of the stator and expand the inner wall of the stator coil. Then, through the elastic component 700, limiting component 800, and extrusion component 900, after expanding the inner wall of the stator coil, the outer wall of the stator coil can be extruded. This solves the problem of changing molds when processing different models of motors, realizes the function of automatically adapting and fine-tuning the stator coil, and improves the preparation speed and practicality before processing.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
