Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically a mechanism for limiting the movement of the inner and outer diameters of the coil during the pressing of flat wire stator wire. Background Technology

[0002] Stator bars are the basic units that make up the generator stator winding. As half of the coil, they are composed of coil sides and ends. The upper and lower layers of bars are assembled into a complete coil through a specific method. They are molded using F-grade epoxy powder mica insulation material, with built-in multi-strand transposed conductors to reduce eddy current losses, and a semiconductor anti-corona layer is applied to the surface to optimize the electric field distribution. The manufacturing of the bars involves precision processes such as hollow and solid strand brazing and brazing of water and electricity joints. In the past, fixed tooling was used. During the commissioning of the wire pressing equipment, if the inner and outer diameters of the stator coil did not meet the requirements, the tooling dimensions had to be disassembled and modified. Before the coil was fully inserted into the iron core, the coil would expand outward, making it difficult to enter the tooling and affecting the final coil condition. After the wire was pressed in, the coil dimensions still needed to be manually corrected. Summary of the Invention

[0003] To address the problems in the prior art, the present invention provides a mechanism for limiting the movement of the inner and outer diameters of the coil during the pressing of the flat wire stator.

[0004] The technical solution adopted by this invention to solve its technical problem is: a mechanism for limiting the movement of the inner and outer diameters of the coil during the pressing of the flat wire stator, comprising a forming mounting plate, a first reducer mounting base fixedly connected to the forming mounting plate, a first reducer fixedly connected to the first reducer mounting base, a first motor mounted on the first reducer, a first coupling connected to the lower end of the first reducer, the first coupling being located at the center of the first reducer mounting base, a first ball screw fixedly connected to the lower end of the first coupling, and a first screw support assembly provided on the outer side of the first ball screw. The first lead screw support assembly is used for center positioning of the first ball screw, so that the first ball screw can rotate within the first lead screw support assembly. The first lead screw support assembly is fixedly connected to the forming mounting plate. The lower end of the first ball screw is threadedly connected to the sliding block to change the longitudinal position of the sliding block. An inner expansion block is slidably provided on the sliding block, and the sliding block is set in a conical structure. The inner expansion block is slidably connected in the groove on the inner guide member. The upper end of the inner expansion block is fixed to the pressure cover. The upper end of the pressure cover is fixed to the middle plate. The upper end of the middle plate is fixed to the forming mounting plate. The rotation control disk rotates on the outside of the middle plate.A sliding block is threaded onto the first ball screw. An outer limit plate is fixedly mounted on the lower end of the pressed mounting plate. A rotation control plate is rotatably mounted inside the outer limit plate. The side end of the rotation control plate is slidably connected to the angle connecting rod. The side end of the angle connecting rod is hinged to the cam follower. The upper end of the cam follower is hinged to the push seat. A movable seat is slidably connected to the upper end of the push seat. The movable seat is threaded onto the second ball screw via a cylinder. The push seat is fixedly connected to the protective cover. The module mounting plate and the protective cover are fixedly connected. The system is slidably connected to the linear guide rail. A second ball screw is rotatably mounted on the screw support assembly. The side end of the second ball screw is connected to the second reducer mounting plate. The side end of the second reducer mounting plate is connected to the second reducer via a second coupling. A second motor is mounted on the second reducer. A second screw support assembly is also fixedly mounted on the side end of the second reducer mounting plate. The guide rail mounting plate is fixedly connected to the linear guide rail, and the guide rail mounting plate is also fixedly connected to the second screw support assembly and the screw support assembly. The lower end of the outer limit plate... The rotating part is equipped with a rotation control disc, which has an inclined groove. An adjusting rod slides along the inclined groove, and the lower end of the adjusting rod is fixedly connected to the outer shaping connecting rod via a needle roller bearing. The lower end of the outer shaping connecting rod is slidably connected to the outer shaping block, and the outer shaping connecting rod passes through the outer shaping block and is fixed to the outer guide plate. The rotation of the first ball screw causes the sliding block to move longitudinally, changing the position of the inner expansion block on the inner guide. The inner guide provides lateral limitation for the inner expansion block, allowing the inner expansion block to slide and adjust on the inner guide, thereby driving... The inner expansion block moves outward, and the push seat drives the rotation control disk to rotate via the cam follower and angle linkage. This rotation control disk, through the adjusting rod and needle roller bearing, drives the outer forming linkage to slide on the outer forming block, changing the position of the outer guide disk. This causes the outer guide disk to move in the opposite direction to the inner expansion block, clamping the outer guide disk and the center copper wire of the inner expansion block. Simultaneously, this stabilizes the connection structure, more securely connecting the forming mounting plate and the outer limit plate, thereby absorbing the vibration force of the forming mounting plate and achieving internal energy absorption.

[0005] Specifically, the second motor drives the second ball screw to rotate through the second reducer and the second coupling, causing the moving seat to slide accordingly, and the lower end of the push seat is fixed to the module mounting plate and the protective cover for limiting.

[0006] Specifically, the movable seat is slidably mounted on the push seat, and the push seat is hinged to the angle linkage via a cam follower, which pulls the angle linkage to move. The rotation control disk is provided with a groove that matches the angle linkage, which drives the rotation control disk to move, so that the rotation control disk rotates at the upper limit of the outer limit disk.

[0007] Specifically, the lower end of the outer limiting plate is provided with a rotation control plate. The angle connecting rod drives the adjusting rod to move through the rotation control plate, so that the adjusting rod drives the outer shaping connecting rod to move, and the outer shaping connecting rod drives the outer guide plate to move. There are multiple outer guide plates, all of which adopt an arc-shaped structure.

[0008] Specifically, the outer guide plate and the inner expansion block both slide on the outer shaping block, and by controlling the movement directions of the outer guide plate and the inner expansion block to be opposite, the center position of the outer guide plate and the inner expansion block is squeezed.

[0009] Specifically, the upper end of the outer shaping block is fixedly connected to the pressure cover, and the guide rail mounting plate is fixedly connected to the upper side of the forming mounting plate.

[0010] Specifically, the sliding block is provided with an inclined groove adapted to the inner expansion block for guiding the inner expansion block.

[0011] Specifically, a fixed side block is fixedly connected to the outer shaping block via a fixed docking rod. A damping rod is hinged to the fixed side block, and the side end of the damping rod is hinged to the docking block. The lower end of the docking block is elastically connected to a spring connecting rod, and the spring connecting rod is fixedly connected to the fixed side block.

[0012] Specifically, the docking block is fixedly connected to the inner wall of the forming mounting plate, and the forming mounting plate and the outer limiting plate are combined through a stable connection structure, thereby improving the buffer protection performance between the forming mounting plate and the outer limiting plate.

[0013] Specifically, the docking block is adjusted by the extension and retraction of a spring connecting rod, and the damping rod follows the extension and retraction of the docking block, and the damping rod has the function of adjusting the following angle.

[0014] The beneficial effects of this invention are:

[0015] First, after this mechanism is put into use, the debugging of the wire crimping equipment is more convenient. Under the premise that the motor torque allows, there is no need to disassemble or modify the tooling. The size of the coil can be changed within a certain range to meet the requirements. The existence of the allowance makes it easier for the coil to enter the tooling, thereby improving the success rate of wire crimping. After the wire is crimped, no manual correction is required, and it can be directly sent to the next process, simplifying the process and improving production accuracy.

[0016] Second, this invention uses the rotation of the first ball screw to cause the sliding block to move longitudinally, changing the position of the inner expansion block on the inner guide. The inner guide then limits the lateral movement of the inner expansion block, allowing it to slide and adjust on the inner guide, thereby driving the inner expansion block to move outward. The push seat drives the rotation control disk to rotate via the cam follower and angle linkage, causing the rotation control disk to drive the outer shaping linkage to slide on the outer shaping block via the adjusting rod and needle roller bearing, changing the position of the outer guide disk. This causes the outer guide disk and the inner expansion block to move in opposite directions, clamping the outer guide disk and the center copper wire of the inner expansion block. At the same time, the structural setting of the connection structure is stabilized, and the forming mounting plate and the outer limiting disk are connected more firmly, thereby absorbing the vibration force of the forming mounting plate and achieving the purpose of internal energy absorption.

[0029] The invention will be further described below with reference to the accompanying drawings. Example 1

[0030] like Figure 1-7As shown, a mechanism for limiting the movement of the inner and outer diameters of the coil during the pressing of the flat wire stator wire according to the present invention includes a forming mounting plate 1, a first reducer mounting base 8 fixedly connected to the forming mounting plate 1, a first reducer 22 fixedly connected to the first reducer mounting base 8, a first motor 24 mounted on the first reducer 22, a first coupling 23 connected to the lower end of the first reducer 22, the first coupling 23 being located at the center of the first reducer mounting base 8, a first ball screw 25 fixedly connected to the lower end of the first coupling 23, a first screw support assembly 21 provided on the outer side of the first ball screw 25, the first screw support assembly 21 being used for center positioning of the first ball screw 25, allowing the first ball screw 25 to rotate within the first screw support assembly 21, the first screw support assembly 21 being fixedly connected to the forming mounting plate 1, and the lower end of the first ball screw 25 being threadedly connected to a sliding block 9, changing the longitudinal position of the sliding block 9. An inner expansion block 10 is slidably provided on the sliding block 9, and the sliding block 9 is set in a conical structure. The inner expansion block 10 is slidably connected in the groove of the inner guide 7. The upper end of the inner expansion block 10 is fixed to the pressure cover 11, the upper end of the pressure cover 11 is fixed to the middle plate 12, and the upper end of the middle plate 12 is fixed to the forming mounting plate 1. The rotation control disk 33 rotates on the outside of the middle plate 12, and the motor stator copper wire is placed at the center position of the outer guide disk 3 and the inner expansion block 10. At this time, the first motor 24 works, driving the first reducer 22 to rotate, driving the first ball screw 25 to rotate. The first ball screw 25 is threadedly connected to the sliding block 9, so that the sliding block 9 can move longitudinally. The inner expansion block 10 is slidably provided on the sliding block 9, and the inner expansion block 10 is limited by the inner guide 7. When the sliding block 9 moves longitudinally, it can push the inner expansion block 10, so that the inner expansion block 10 slides and adjusts on the inner guide 7, so that the inner expansion block 10 expands outward.A sliding block 9 is threaded onto the first ball screw 25. An outer limiting plate 2 is fixedly installed at the lower end of the pressed mounting plate 1. A rotation control plate 33 is rotatably installed inside the outer limiting plate 2. The side end of the rotation control plate 33 is slidably connected to the angle connecting rod 6. The side end of the angle connecting rod 6 is hinged to the cam follower 19. The upper end of the cam follower 19 is hinged to the push seat 17. A movable seat 15 is slidably connected to the upper end of the push seat 17. The movable seat 15 is threaded onto the second ball screw 31 through the cylinder. The push seat 17 is fixedly connected to the protective cover 18. The module is installed... Mounting plate 13 and protective cover 18 are fixedly connected. Module mounting plate 13 and protective cover 18 are slidably connected on linear guide rail 32. A second ball screw 31 is rotatably mounted on the screw support assembly 27. The side end of the second ball screw 31 is connected to the second reducer mounting plate 14. The side end of the second reducer mounting plate 14 is connected to the second reducer 28 via the second coupling 29. A second motor 30 is mounted on the second reducer 28. A second screw support assembly 26 is also fixedly mounted on the side end of the second reducer mounting plate 14. Guide rail mounting plate 16 is connected to the linear guide rail. 32. Fixed connection: The guide rail mounting plate 16 is also fixedly connected to the second lead screw support assembly 26 and the lead screw support assembly 27. A rotation control disk 33 is rotatably provided at the lower center of the outer limit disk 2. The rotation control disk 33 is provided with an inclined groove, and an adjusting rod 34 is slidably provided on the inclined groove. The lower end of the adjusting rod 34 is fixedly connected to the outer shaping connecting rod 4 through the needle roller bearing 20. The lower end of the outer shaping connecting rod 4 is slidably connected on the outer shaping block 5, and the outer shaping connecting rod 4 passes through the outer shaping block 5 and is fixed to the outer guide disk 3. By rotating the first ball screw 25, the sliding block... 9. The longitudinal movement changes the position of the inner expansion block 10 on the inner guide 7. The inner guide 7 then laterally limits the inner expansion block 10, allowing it to slide and adjust on the inner guide 7. This causes the inner expansion block 10 to move outward. The push seat 17, through the cam follower 19 and the angle connecting rod 6, drives the rotation control disk 33 to rotate. The rotation control disk 33, through the adjusting rod 34 and the needle roller bearing 20, drives the outer shaping connecting rod 4 to slide on the outer shaping block 5, changing the position of the outer guide disk 3. This causes the outer guide disk 3 to move in the opposite direction to the inner expansion block 10.

[0031] The second motor 30 drives the second ball screw 31 to rotate via the second reducer 28 and the second coupling 29, causing the movable seat 15 to slide accordingly. The lower end of the push seat 17 is fixed to the module mounting plate 13 and the protective cover 18 for limiting its position. The second motor 30 also operates, driving the second coupling 29 to rotate via the second reducer 28. The second reducer 28 drives the second screw support assembly 26 to rotate, changing the position of the movable seat 15. The movable seat 15 and the push seat 17 are limited by the module mounting plate 13, the second reducer mounting plate 14, and the linear guide rail 32, allowing for lateral movement. The lower end of the push seat 17 is controlled by a cam follower 1. 9 is hinged to the angle connecting rod 6, causing the angle connecting rod 6 to move. The angle connecting rod 6 is slidably connected to the rotation control disk 33 inside the outer limit disk 2, so that the rotation control disk 33 rotates inside the outer limit disk 2. When the rotation control disk 33 rotates, it drives the adjusting rod 34 to move in coordination. The adjusting rod 34 slides on the inclined groove of the rotation control disk 33, changing the position of the needle roller bearing 20. This causes the needle roller bearing 20 to drive the outer shaping connecting rod 4 to slide on the outer shaping block 5. The lower end of the outer shaping connecting rod 4 is connected to the outer guide disk 3, causing the outer guide disk 3 to move in coordination. The outer guide disk 3 moves inward, thereby extruding the stator copper wire through the outer guide disk 3 and the inner expansion block 10, facilitating the processing of the stator copper wire.

[0032] The movable seat 15 is slidably mounted on the push seat 17. The push seat 17 is hinged to the angle connecting rod 6 via the cam follower 19, which pulls the angle connecting rod 6 to move. The rotation control disk 33 is provided with a groove that matches the angle connecting rod 6, which drives the rotation control disk 33 to move, so that the rotation control disk 33 rotates at the upper limit of the outer limit disk 2.

[0033] The lower end of the outer limit plate 2 is provided with a rotation control plate 33. The angle connecting rod 6 drives the adjusting rod 34 to move through the rotation control plate 33, so that the adjusting rod 34 drives the outer shaping connecting rod 4 to move, and the outer shaping connecting rod 4 drives the outer guide plate 3 to move. There are multiple outer guide plates 3, and all of them adopt an arc-shaped structure.

[0034] Both the outer guide plate 3 and the inner expansion block 10 slide on the outer shaping block 5, and by controlling the movement directions of the outer guide plate 3 and the inner expansion block 10 to be opposite, the center position of the outer guide plate 3 and the inner expansion block 10 is squeezed.

[0035] The upper end of the outer shaping block 5 is fixedly connected to the pressure cover 11, and the guide rail mounting plate 16 is fixedly connected to the upper side of the forming mounting plate 1.

[0036] The sliding block 9 is provided with an inclined groove that is adapted to the inner expansion block 10 for guiding the inner expansion block 10.

[0037] A fixed side block 37 is fixedly connected to the outer shaping block 5 via a fixed docking rod 40. A damping rod 38 is hinged to the fixed side block 37. The side end of the damping rod 38 is hinged to the docking block 36. The lower end of the docking block 36 is elastically connected to the spring connecting rod 39, and the spring connecting rod 39 is fixedly connected to the fixed side block 37.

[0038] The working principle is as follows: During use, the motor stator copper wire is placed at the center of the outer guide plate 3 and the inner expansion block 10. At this time, the first motor 24 works, driving the first reducer 22 to rotate, which in turn drives the first ball screw 25 to rotate. The first ball screw 25 is threadedly connected to a sliding block 9, allowing the sliding block 9 to move longitudinally. The inner expansion block 10 is slidably mounted on the sliding block 9, and the inner expansion block 10 is limited by the inner guide 7. When the sliding block 9 moves longitudinally, it can push the inner expansion block 10, allowing the inner expansion block 10 to slide and adjust on the inner guide 7, causing the inner expansion block 10 to expand outward. At the same time, the second motor 30 also works. The second motor 30 drives the second coupling 29 to rotate through the second reducer 28. The second reducer 28 drives the second screw support assembly 26 to rotate, changing the position of the moving seat 15 and moving it. Seat 15 and push seat 17 are limited by module mounting plate 13, second reducer mounting plate 14 and linear guide rail 32 for lateral movement. The lower end of push seat 17 is hinged to angle link 6 through cam follower 19, which drives angle link 6 to follow the movement. Angle link 6 is slidably set with rotation control disk 33 in outer limit disk 2, so that rotation control disk 33 rotates in outer limit disk 2. When rotation control disk 33 rotates, it drives adjustment rod 34 to move in coordination. Adjustment rod 34 slides on the inclined groove of rotation control disk 33, changing the position of needle roller bearing 20, so that needle roller bearing 20 drives outer shaping link 4 to slide on outer shaping block 5. The lower end of outer shaping link 4 is connected to outer guide disk 3, so that outer guide disk 3 follows the movement. Outer guide disk 3 moves inward, thereby squeezing stator copper wire through outer guide disk 3 and inner expansion block 10, which facilitates stator copper wire processing. Example 2

[0039] Based on Example 1, such as Figure 8-9 As shown, the mating block 36 is fixedly connected to the inner wall of the forming mounting plate 1. The forming mounting plate 1 and the outer limiting plate 2 are combined through the stable connection structure 35, which improves the buffer protection performance between the forming mounting plate 1 and the outer limiting plate 2.

[0040] The docking block 36 is telescopically adjustable via the spring connecting rod 39, and the damping rod 38 follows the telescopic movement of the docking block 36. The damping rod 38 also has an angle adjustment function. In use, the fixed side block 37 is fixed to the outer limiting plate 2, and the docking block 36 is docked with the forming mounting plate 1. When the forming mounting plate 1 vibrates, the docking block 36 is subjected to force, which is transmitted to the spring connecting rod 39 and the damping rod 38. The spring connecting rod 39 can be compressed, and the damping rod 38 can also telescopically move. At the same time, the damping rod 38 is hinged to the fixed side block 37 and the docking block 36, and can follow the angle change, thereby achieving the purpose of multi-point docking and improving the connection stability of the forming mounting plate 1 and the outer limiting plate 2.
