Description

Technical Field

[0001] The present invention belongs to the technical field of motor stator production and processing, and in particular relates to a coil transition line finishing device for a block-type circular stator. Background Art

[0002] The circular core stator is usually composed of multiple stator core blocks, which are assembled to form a complete circular stator core (such as Figure 12 This structure helps improve the overall performance and efficiency of the motor.

[0003] During the production and processing of the circular stator, the coils on the two segmented cores are usually wound together, that is, the segmented cores are double wound. The coils on the two segmented cores are usually connected by a bridge wire. However, the bridge wire is higher than the coil. Some bridge wires are close to the outside of the stator, while others are close to the inside of the stator (such as Figure 12 As shown), therefore, it is necessary to shape the bridge wire to prevent the bridge wire from affecting the assembly of the motor housing and the rotor. In response to the above technical problems, the applicant has retrieved some existing technologies to achieve the shaping of the bridge wire. For example, the patent publication number is CN111769701B. Its main technical means is that after the stator is placed in the positioning groove of the stator fixture base, the second drive component drives the stator pressure block downward to press the stator to prevent the stator from floating; the first drive component drives the core shaft in the positioning groove to lift up, so that the stator bridge wire on the stator exceeds the stator inner diameter range; the expansion component runs to expand the stator bridge wire and spread the stator bridge wire on the stator; the third drive component drives the shaping block downward to press and shape it. According to the applicant's analysis, the disadvantage of this technical solution is that when the expansion component expands the bridge wire, the expanded bridge wire part will still be in an inclined state. At this time, if the bridge wire is directly pressed down to reshape it, the highest part of the inclined bridge wire will be pressed down first, and the vertical parts corresponding to the two ends of the bridge wire will be easily bent when pressed down (such as Figure 13 Continuing to press down will cause the bridge wires to be stacked up in layers, which may cause the stacked parts of the bridge wires to bulge out. On the one hand, they are prone to breakage when squeezed, and on the other hand, the bulging parts are higher than the height of other shaped bridge wires, which may affect the subsequent assembly of the motor housing and rotor. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the existing technology and provide a coil transition wire straightening device for a segmented circular stator to solve the technical problem that when the inclined bridge wire is pressed down after expansion, the bridge wire is stacked up and down, resulting in the stacked part of the bridge wire protruding. On the one hand, it is easy to break when squeezed, and on the other hand, the protruding part is higher than the height of other shaped bridge wires, which may affect the subsequent assembly of the motor housing and the rotor.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] like Figures 1-11 As shown, a coil transition line finishing device for a segmented circular stator includes a stator fixture 3 for placing the circular stator, and the device also includes:

[0043] The frame 2 is connected to the driving member 1, and the frame 2 includes a mounting plate 21, an outer cover 23, and a cable drum 24. The mounting plate 21 and the cable drum 24 are connected by the outer cover 23. The mounting plate 21 is equipped with a telescopic member 22, which extends into the outer cover 23.

[0044] The shaping mechanism 4 includes a plurality of connecting rods 41, which are movably connected to the output end of the telescopic member 22. The other end of the connecting rod 41 is movably connected to a slider 42. A limit frame 43 is evenly provided on the whole wire drum 24. The slider 42 is slidably installed in the limit frame 43. A wire hooking rod 44 is installed on one side of the slider 42. The wire hooking rod 44 passes through the whole wire drum 24.

[0045] A limiting mechanism 5 is installed at the bottom of the entire cable drum 24;

[0046] Driving part four 6, a driving part four 6 is installed at the bottom of the stator fixture 3.

[0047] In one case of this embodiment, the driving part 1 can be a pneumatic slide, which provides power for the frame 2 to move up and down; the telescopic part 22 can be a cylinder, and the telescopic part 22 can be extended and retracted to drive several connecting rods 41 to move; the driving part 46 can be a rotary cylinder, which provides power for the rotation of the stator fixture 3; the sliding installation method of the slider 42 and the limit frame 43 can be that there are support plates on both sides of the slider 42, and the limit frame 43 has slide grooves on opposite sides, and the support plates are stuck in the slide grooves, so that the slider 42 can only move horizontally along the limit frame 43 when sliding.

[0048] In actual application of this embodiment, the circular stator to be shaped is placed on the stator fixture 3, and then the frame 2 is moved downward by the driving member 1, and at the same time, the connecting rod 41 is moved by the telescopic member 22, so that the connecting rod 41 drives the slider 42 to slide in the limit frame 43, and the slider 42 drives the hooking rod 44 to adjust its position; when the bridge line near the outside of the stator is to be shaped, the hooking rod 44 is first adjusted to the outside of the bridge line, and then the hooking rod 44 is moved downward by the driving member 1 so that the hooking rod 44 is located between the bridge line and the stator, and then the hooking rod 44 is moved inward, thereby slowly hooking the bridge line; when the bridge line near the inside of the stator is to be shaped, the hooking rod 44 is first adjusted to the inside of the bridge line, Then, the wire hooking rod 44 is moved downward by the driving member 1 so that the wire hooking rod 44 is located between the bridge wire and the stator, and then the wire hooking rod 44 is moved outward to slowly hook the bridge wire; after hooking the bridge wire, the stator fixture 3 is driven by the driving member 46 to rotate the circular stator, so that after rotation, the hooked bridge wire will bend and deform, and be in a semi-lying state. Finally, the bridge wire is pressed downward by the limiting mechanism 5 to be flattened. This shaping method can effectively prevent the bridge wires from being layered and stacked when being pressed down, prevent the stacked parts of the bridge wires from protruding, effectively prevent the stacked bridge wires from being squeezed and broken, and prevent the height of the bridge wires from being too high to affect the subsequent motor housing and rotor matching.

[0049] Furthermore, the connecting rod 41 includes a sleeve 411, a sleeve 1 412 and a sleeve 2 413. The sleeve 1 412 and the sleeve 2 413 are respectively sleeved on the two ends of the sleeve 411. A baffle 4111 is provided in the sleeve 411. An elastic member 1 414 is provided between the baffle 4111 and the sleeve 1 412. An elastic member 2 415 is provided between the baffle 4111 and the sleeve 2 413.

[0050] In one case of this embodiment, elastic member 1 414 may be a spring, and elastic member 1 414 is always in a stretched state; elastic member 2 415 may be a spring, and elastic member 2 415 is always in a contracted state; elastic member 1 414 assists sleeve 1 412 to contract into sleeve 411, and elastic member 2 415 assists sleeve 2 413 to extend out of sleeve 411.

[0051] In actual application of this embodiment, the connecting rod 41 can be elastically extended and retracted, so that the positions of the slider 42 and the thread hooking rod 44 can be adjusted.

[0052] Furthermore, a second driving member 4122 is installed in the first sleeve 412, a circular plate 4123 is provided at the output end of the second driving member 4122, and a plurality of locking blocks 41231 are provided on the periphery of the circular plate 4123. A third driving member 4132 is installed in the second sleeve 413, a circular plate 4133 is provided at the output end of the third driving member 4132, and a plurality of locking blocks 41331 are provided on the periphery of the circular plate 4133. A limiting step 4112 and a limiting step 4112 are provided in the sleeve 411 respectively. 13. Limiting step 1 4112 and limiting step 2 4113 limit locking block 1 41231 and locking block 2 41331, respectively. Slideway 1 4114 and slideway 2 4115 are respectively provided in sleeve 411. When locking block 1 41231 rotates to overlap with slideway 1 4114 or locking block 2 41331 rotates to overlap with slideway 2 4115, locking block 1 41231 slides in slideway 1 4114 and locking block 2 41331 slides in slideway 2 4115.

[0053] In one aspect of this embodiment, the second driving member 4122 and the third driving member 4132 may both be micro motors, providing power for the rotation of the first circular plate 4123 and the second circular plate 4133 .

[0054] In actual application of this embodiment, when the bridge wire near the outside of the stator is to be shaped, after several hooking rods 44 hook the corresponding shorter bridge wire and bend it, the driving member four 6 is closed, and the driving member three 4132 at the hooking rod 44 corresponding to the bent and deformed bridge wire is started, so that the circular plate two 4133 rotates, and the locking block two 41331 coincides with the slideway two 4115. Due to the rebound ability of the elastic member two 415, the sleeve two 413 stretches, so that the slider 42 drives the hooking rod 44 corresponding to the shorter bridge wire away from the shorter bridge wire that has been bent and deformed. Then the driving member four 6 is started to rotate the stator fixture 3, so that the hooking rod 44 corresponding to the longer bridge wire hooks the longer bridge wire, and the longer bridge wire is also bent and deformed. In this way, the bridge wires of different lengths can be bent and deformed. In this process, the hooking rod 44 corresponding to the shorter bridge wire will not collide with the shorter bent and deformed bridge wire. The bridge wires are in contact; when the bridge wires on the inner side of the stator need to be shaped, after a number of hooking rods 44 hook the corresponding shorter bridge wires and bend and deform them, the driving member 46 is closed, and the driving member 2 4122 at the hooking rod 44 corresponding to the bent and deformed bridge wire is started, so that the circular plate 1 4123 rotates, and the locking block 1 41231 coincides with the slide 1 4114. Due to the resilience of the elastic member 1 414, the sleeve 1 412 contracts, so that the slider 42 drives the hooking rod 44 corresponding to the shorter bridge wire away from the shorter bridge wire that has been bent and deformed. Then the driving member 46 is started to rotate the stator fixture 3, so that the hooking rod 44 corresponding to the longer bridge wire hooks the longer bridge wire and causes the longer bridge wire to bend and deform as well. In this way, the bridge wires of different lengths can be bent and deformed. During this process, the hooking rod 44 corresponding to the shorter bridge wire will not contact the shorter bridge wire that has been bent and deformed.

[0055] Furthermore, a plurality of through holes 242 are formed on the wire reel 24 , and the wire hooking rod 44 passes through the through holes 242 .

[0056] In actual application of this embodiment, the wire hooking rod 44 can move within the range of the through hole 242, so that the position of the wire hooking rod 44 can be adjusted more flexibly, so that the wire hooking rod 44 can be adjusted to a suitable position to hook the bridge wire.

[0057] Furthermore, a thread hooking groove 441 is formed on the thread hooking rod 44 .

[0058] In one case of this embodiment, the wire hooking groove 441 is an inwardly concave arc groove, which can easily hook the bridge wire and drive the bridge wire to bend after hooking the bridge wire.

[0059] like Figure 11 As shown, the limiting mechanism 5 includes:

[0060] A plurality of inner limit plates 51 are arranged equidistantly around the periphery. A second telescopic member 53 is installed on the inner side of the inner limit plate 51. The second telescopic member 53 is installed at the bottom of the whole wire drum 24. When the inner limit plate 51 moves outward, it slowly approaches the wire hook rod 44.

[0061] A plurality of outer limit plates 52 are equidistantly arranged circumferentially. A telescopic member 3 54 is installed on the outer side of the outer limit plate 52. The telescopic member 3 54 is installed at the bottom of the whole wire drum 24. When the outer limit plate 52 moves inward, it slowly approaches the wire hook rod 44.

[0062] In one case of this embodiment, the inner limit plate 51 and the outer limit plate 52 are both arc-shaped; the telescopic part 2 53 and the telescopic part 3 54 can both be cylinders to provide power for the movement of the inner limit plate 51 and the outer limit plate 52; in addition, the bottom of the inner limit plate 51 and the outer limit plate 52 are flush with the bottom of the hook rod 44.

[0063] In actual application of this embodiment, when the bridge wire is to be shaped, after adjusting the position of the hook rod 44 so as to hook the bridge wire for bending and deformation, the inner limit plate 51 is moved outward and the outer limit plate 52 is moved inward by the telescopic member 2 53 and the telescopic member 3 54, so that the coil on the segmented stator is located between the inner limit plate 51 and the outer limit plate 52, so that the bridge wire can be restricted between the inner limit plate 51 and the outer limit plate 52, and the range of movement of the bridge wire is within the range of the coil on the segmented stator, and will not exceed the inner and outer walls of the segmented stator, so that when the bridge wire is shaped During shaping, the shaped bridge wire is located within the range of the coil on the segmented stator, so it is not easy to affect the matching of the motor housing and the rotor; in addition, after the bridge wire is shaped, the positions of the inner limit plate 51 and the outer limit plate 52 are adjusted by the telescopic member 2 53 and the telescopic member 3 54, so that the inner limit plate 51 and the outer limit plate 52 are located within the range of the coil on the segmented stator, and then the frame 2 is moved downward by the driving member 1, so that the inner limit plate 51 and the outer limit plate 52 are moved downward to press the bridge wire, so that the bridge wire is flattened, effectively avoiding the raised part of the shaped bridge wire.

[0064] Furthermore, a plurality of rolling elements 55 are installed at the bottom of the inner limiting plate 51 and the outer limiting plate 52 .

[0065] In one case of this embodiment, the rolling member 55 may be a roller, or a component that can roll and flatten the bridge line.

[0066] In actual application of this embodiment, after the bridge wire is shaped, the inner limit plate 51 and the outer limit plate 52 move down to press the bridge wire so that the bridge wire is flattened. At this time, the driving member 4 6 is started to make the stator fixture 3 drive the circular stator to rotate, so that the rolling members 55 on the inner limit plate 51 and the outer limit plate 52 will roll, thereby further compacting the flattened bridge wire and preventing the bridge wire from warping and affecting the subsequent assembly of the motor housing and the rotor.

[0067] like Figure 4-Figure 7 As shown, a sinking groove 241 is provided on the whole line drum 24, and a circular ring 46 is rotatably installed at the center position of the sinking groove 241. One end of the limit frame 43 is fixed to the outside of the circular ring 46, and the other end of the limit frame 43 slides relative to the inner wall of the sinking groove 241. Guide grooves 244 are evenly provided on the inner wall of the sinking groove 241, and the end of the limit frame 43 close to the guide groove 244 is stuck in the guide groove 244 and slides along the guide groove 244.

[0068] In one case of this embodiment, the sinking groove 241 is circular, and the limiting frame 43 can perform circular motion around the ring 46.

[0069] In actual application of this embodiment, the limiting frame 43 slides along the sinking groove 241 to adjust the position of the thread hooking rod 44.

[0070] Furthermore, a plurality of spacer plates 243 are circumferentially arranged at equal intervals in the sinking groove 241 , the limiting frame 43 is located between two adjacent spacer plates 243 , and a plurality of elastic members 45 are provided between the side surfaces of the limiting frame 43 and the adjacent spacer plates 243 .

[0071] In one case of this embodiment, the elastic member 3 45 may be a spring, wherein the rebound capability of the elastic member 3 45 is greater than the rebound capability of the elastic member 1 414 and the elastic member 2 415 .

[0072] In actual application of this embodiment, when the bridge wire near the outside of the stator is shaped, before the hooking rod 44 hooks the bridge wire for shaping, the outer limit plate 52 is pressed against the hooking rod 44 through the telescopic member 3 54. When shaping, the driving member 4 6 drives the circular stator on the stator fixture 3 to rotate, and the shorter bridge wire is hooked and deformed by the corresponding hooking rod 44, while the longer bridge wire has a gap between the hooking rods 44 and cannot bend and deform. At this time, the driving member 3 4132 at the hooking rod 44 corresponding to the bridge wire that is bent and deformed is started, so that the locking block 2 41331 coincides with the slide 2 4115, unlocking the sleeve 2 413 so that the sleeve 2 413 can extend out of the sleeve 411. At the same time, the circular stator is still rotating, and the hooking rod 4 4 will be resisted by the bridge line, and the limit frame 43 here will move along the guide groove 244, and the hooking rod 44 corresponding to the longer bridge line will slowly approach the longer bridge line until the longer bridge line is bent and deformed. At this time, the driving member 4 6 is started to rotate in the opposite direction, so that the hooking rod 44 is away from the bending position of the bridge line. At this time, due to the rebound ability of the elastic member 3 45, the displaced limit frame 43 slowly returns to its original position, and the extended sleeve 2 413 also slowly shrinks into the sleeve 411. When the limit frame 43 returns to its original position, the circular plate 2 4133 is located at the limiting step 2 4113, and the corresponding driving member 3 4132 is controlled to start, so that the circular plate 2 4133 rotates, so that the locking block 2 41331 and the slide 2 4115 are staggered, so that the sleeve 2 413 is restricted;When the bridge wire near the inner side of the stator is shaped, before the wire hooking rod 44 hooks the bridge wire for shaping, the inner limit plate 51 is pressed against the wire hooking rod 44 through the telescopic member 2 53. When shaping is performed, the driving member 4 6 drives the circular stator on the stator fixture 3 to rotate, and the shorter bridge wire is hooked and deformed by the corresponding wire hooking rod 44, while the longer bridge wire has a gap between the wire hooking rods 44 and cannot bend and deform. At this time, the driving member 2 4122 at the wire hooking rod 44 corresponding to the bridge wire that is bent and deformed is started, so that the locking block 1 41231 coincides with the slide 1 4114, unlocking the sleeve 1 412, so that the sleeve 1 412 is retracted into the sleeve 411. At the same time, the circular stator is still rotating, and the wire hooking rod 44 corresponding to the bent and deformed bridge wire will be pressed against the bridge wire. When the guide rail 42 is held in place, the limit frame 43 here will displace along the guide groove 244, and the corresponding wire hooking rod 44 of the longer bridge wire will gradually approach the longer bridge wire until the longer bridge wire is bent and deformed. At this time, the driving member 46 is activated to rotate in the opposite direction, causing the wire hooking rod 44 to move away from the bent position of the bridge wire. At this time, due to the rebound ability of the elastic member 3 45, the displaced limit frame 43 will slowly return to its original position, and the sleeve 1 412 retracted into the sleeve 411 will slowly extend out of the sleeve 411. When the limit frame 43 returns to its original position, the circular plate 1 4123 is located at the limit step 1 4112, controlling the corresponding driving member 2 4122 to activate, causing the circular plate 1 4123 to rotate, thereby staggering the locking block 1 41231 and the slideway 1 4114, thereby restricting the sleeve 1 412.

[0073] like Figure 6-Figure 7 As shown, sleeve 1 412 is connected to the output end of telescopic member 1 22 through a universal joint, and sleeve 2 413 is connected to slider 42 through a universal joint.

[0074] In one case of this embodiment, the universal coupling can be composed of steel balls and ball grooves, wherein a connector 221 is provided at the output end of the telescopic member 22, and a plurality of steel balls 47 are fixed to the outer periphery of the connector 221, and a ball groove 4121 is provided at one end of the sleeve 412, and the steel ball 47 is movably clamped in the ball groove 4121, so that the sleeve 412 can move in all directions, and a steel ball 48 is fixed on the slider 42, and a ball groove 4131 is provided at one end of the sleeve 413, and the steel ball 48 is movably clamped in the ball groove 4131, so that the sleeve 413 can move in all directions.

[0075] In actual application of this embodiment, the connecting rod 41 can be universally movable through the universal coupling, so as to facilitate the displacement of the limit frame 43 and the slider 42.

[0076] Working principle: When the bridge wire near the outside of the stator needs to be shaped, first adjust the wire hook rod 44 to the outside of the bridge wire, then move the wire hook rod 44 downward through the driving member 1 so that the wire hook rod 44 is located between the bridge wire and the stator, and then move the wire hook rod 44 inward to slowly hook the bridge wire. At this time, the outer limit plate 52 is pressed against the wire hook rod 44 through the telescopic member 3 54, and then the driving member 4 6 is turned on to drive the circular stator on the stator fixture 3 to rotate. The shorter bridge wire is hooked and bent by the corresponding wire hook rod 44, while the longer bridge wire has a gap between the wire hook rods 44 and cannot be bent and deformed. At this time, the driving member 3 4132 at the wire hook rod 44 corresponding to the bridge wire that is bent and deformed is started, so that the locking block 2 41331 coincides with the slide 2 4115, unlocking the sleeve 2 413 so that the sleeve 2 413 can extend out of the sleeve 411. At the same time , the stator is still rotating, and the hooking rod 44 corresponding to the bent and deformed bridge line will be held against by the bridge line, and the limit frame 43 here will move along the guide groove 244, and the hooking rod 44 corresponding to the longer bridge line will slowly approach the longer bridge line until the longer bridge line is bent and deformed. At this time, the driving member 46 is started to rotate in the opposite direction, so that the hooking rod 44 is away from the bent position of the bridge line. At this time, due to the rebound ability of the elastic member 3 45, the displaced limit frame 43 slowly returns to its original position, and the extended sleeve 2 413 also slowly shrinks into the sleeve 411. When the limit frame 43 returns to its original position, the circular plate 2 4133 is located at the limiting step 2 4113, and the corresponding driving member 3 4132 is controlled to start, so that the circular plate 2 4133 rotates, so that the locking block 2 41331 is staggered with the slide 2 4115, so that the sleeve 2 413 is restricted.When the bridge wire near the inner side of the stator is to be shaped, the wire hooking rod 44 is first adjusted to the inner side of the bridge wire, and then the wire hooking rod 44 is moved down by the driving member 1 so that the wire hooking rod 44 is located between the bridge wire and the stator, and then the wire hooking rod 44 is moved outward to slowly hook the bridge wire. At this time, the inner limit plate 51 is pressed against the wire hooking rod 44 by the telescopic member 2 53, and then the driving member 4 6 is turned on to drive the circular stator on the stator fixture 3 to rotate. The shorter bridge wire is hooked by the corresponding wire hooking rod 44 and bent and deformed, while the longer bridge wire has a gap between the wire hooking rods 44 and cannot be bent and deformed. At this time, the control The driving member 2 4122 at the hooking rod 44 corresponding to the bridge line that is bent and deformed is started, so that the locking block 1 41231 coincides with the slide 1 4114, unlocking the sleeve 1 412, and retracting the sleeve 1 412 into the sleeve 411. At the same time, the stator is still rotating, and the hooking rod 44 corresponding to the bent and deformed bridge line will be held against by the bridge line, and the limit frame 43 here will move along the guide groove 244, and the hooking rod 44 corresponding to the longer bridge line will slowly approach the longer bridge line until the longer bridge line is bent and deformed. At this time, the driving member 46 is started to rotate in the opposite direction, so that The hook rod 44 is moved away from the bending position of the bridge wire. At this time, due to the resilience of the elastic member 3 45, the limit frame 43 that has been displaced slowly returns to its original position, and the sleeve 1 412 retracted into the sleeve 411 slowly extends out of the sleeve 411. When the limit frame 43 returns to its original position, the circular plate 1 4123 is located at the limiting step 1 4112, and the corresponding driving member 2 4122 is controlled to start, so that the circular plate 1 4123 rotates, so that the locking block 1 41231 and the slide 1 4114 are staggered, so that the sleeve 1 412 is restricted. At this time, all the bridge wires are in a semi-lying state, and the sleeve 1 412 is retracted. Component 2 53 and telescopic component 3 54 adjust the positions of the inner and outer limit plates 51 52 so that they are within the range of the coils on the segmented stator. Frame 2 is then moved downward by driving component 1 1 , causing the inner and outer limit plates 51 52 to move downward and press against the bridge wires, flattening them. This shaping method effectively prevents the bridge wires from overlapping when pressed downward, preventing the overlapping portions of the bridge wires from protruding, effectively preventing the stacked bridge wires from breaking after being squeezed, and preventing the bridge wires from being too high, which could affect the subsequent assembly of the motor housing and rotor.
