Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and specifically to a motor stator lead wire bending and shaping device. Background Art

[0002] The motor stator is composed of an iron core and coils embedded in the inner teeth of the iron core. Since the shapes of the partial coils exposed at both ends of the iron core are irregular, it causes certain obstacles during the assembly of the stator and the rotor or the stator and the motor housing. Therefore, it is necessary to shape the stator coils before assembly, including shaping the end height, inner circle, and outer circle of the coils. The existing shaping methods are generally divided into two types. One is to perform knocking and shaping manually, and the second method is to perform internal shaping on the stator coils through an internal shaping die or a stator shaping machine.

[0003] After retrieval, a motor stator coil shaping device is disclosed in the publication number: CN108667230B, which includes a processing table. Above the processing table, a clamping mechanism for clamping and fixing the stator is provided. Above and below the clamping mechanism, an upper die and a lower die for shaping the stator coils are respectively provided; both sides of the upper die and the lower die are connected with a driving and guiding mechanism located on the processing table, and the clamping mechanism is connected to the driving and guiding mechanism through a bearing. The present invention solves the problems that the shaped dimensions are inconsistent due to manual shaping and the enameled wire in the stator coils is prone to paint peeling or even breakage. In addition, the structure of the present invention is simple, easy to repair and maintain, and safe and easy to operate.

[0004] When the stator is clamped by an artificial arc-shaped clamp in the above application, the center point of the stator cannot coincide well with the center points between the upper die and the lower die. When the upper die and the lower die move relative to each other, due to the locking of the arc-shaped clamp, one end of the stator will be subjected to excessive force, while the other end will be under insufficient force, thus affecting the shaping effect of the stator coils. Moreover, when the stator is clamped by the arc-shaped clamp, the staff also needs to hold the stator while screwing the screw and nut, which is time-consuming and laborious.

[0011] Preferably, shaping grooves are formed on the surface of the shaping die, and the side walls of the shaping grooves are formed as arc-shaped sides adapted to the coil end faces of the stator body. The shaping die includes a die body and a housing. One end of the housing is fixedly connected to the outer side wall of the die body. A driver is fixedly arranged on the upper surface of the upper die body. Grooves are formed on the inner wall of the shaping groove, and a rotating plate is rotatably connected inside the grooves. A side shaping member is installed on the outer side wall of the rotating plate, and the driving end of the driver is fixedly connected to the inner wall of the upper rotating plate.

[0012] Preferably, the side shaping member includes a cylinder and a rod. One end of the cylinder is fixedly connected to the outer wall of the rotating plate. Slots are respectively formed on both sides of the cylinder. One end of the rod is slidably arranged inside the cylinder. A connecting member is sleeved on the outer wall of the cylinder. The inner wall of the connecting member passes through the slots and is fixedly connected to the outer side wall of the rod. A second spring is fixedly connected to the inner bottom wall of the cylinder, and the other end of the second spring is fixedly connected to one end of the rod.

A plurality of connecting holes are formed at the top end of the lower rod, and a plurality of spring telescopic connecting rods are embedded and connected to the bottom end of the upper rod.

[0013] Working principle: When shaping the coil of the motor stator body, due to the elastic driving force of the first spring, one end of the support plate slides below the extension arm, so as to horizontally support the extension arm and the semi-ring body, so that the support table can place the stator body in a horizontal state. The stator body is placed in the placement channel, so that the distance between the upper end of the stator body and the upper shaping die is the same as the distance between the lower end of the stator body and the lower shaping die, so that the center point of the stator body is automatically aligned with the center point between the two shaping dies, so that the two shaping dies can evenly press the upper and lower ends of the stator body to avoid uneven stress and improve the shaping effect of the stator body coil.

[0014] During shaping, the upper cylinder extends by a certain amplitude first. The extension of the cylinder drives the upper shaping die to descend. The descent of the shaping die drives the connecting arm to descend. The descent of the connecting arm drives the tooth groove to descend until the tooth ring and the tooth groove are misaligned, then the operation stops. Through the meshing transmission between the tooth groove and the gear, when the connecting arm descends, it drives the tooth ring to rotate. The rotation of the tooth ring drives the lead screw to rotate. The rotation of the lead screw drives the threaded barrel to slide horizontally. The sliding of the threaded barrel drives the gripper to move towards the stator body. Thus, while the tooth ring and the tooth groove are misaligned, the gripper tightly presses against the stator body for clamping and fixing, achieving automatic clamping of the stator body and improving the stability during the shaping of the stator body.

[0015] Subsequently, the lower cylinder also runs and extends by a certain amplitude first, driving the lower shaping die to rise. The rise of the shaping die drives the push arm to rise. The push arm rises along the inclined plane and gradually pushes open the extension plate. The extension plate drives the support plate to slide outward, causing the support plate and the extension arm to be misaligned. The lack of support under the extension arm will drive the semi-ring body to rotate downward under the action of gravity, thus enabling the semi-ring body to rotate automatically, avoiding blocking the rise of the lower shaping die for shaping the stator body coil. At this time, the stator body has been clamped and fixed by the fixing component, so the stability of the stator body will not be affected even in the case of lack of support from the semi-ring body.

[0016] Then the two cylinders continue to extend synchronously, causing the upper and lower shaping dies to respectively press against both ends of the stator body, enabling the two ends of the coil of the stator body to respectively enter the shaping grooves for end height shaping. When the shaping die presses against the stator body, the two rod bodies will press against each other and respectively generate contraction sliding inside the cylinder. When the rod body slides inside the cylinder, it will drive the connecting piece to move towards the rotating plate. The movement of the connecting piece drives the rotating bracket to rotate, thereby pushing the wedge block to slide and expand, making the arc surface of the wedge block press against the inner side of the end of the stator body coil. The arc side surface of the shaping groove will fit against the outer side of the end of the stator body coil. At this time, the driver is operated. The driver drives the upper rotating plate and the side shaping parts to rotate, and when the spring telescopic connecting rod rotates and aligns with the connecting hole, it automatically inserts, thus automatically connecting the two connecting rods, enabling a single set of drivers to simultaneously drive the two side shaping parts to shape the upper and lower ends of the stator body coil. By driving the wedge block to rotate through the driver, the coil of the stator body completes the shaping of the entire inner and outer circles, realizing an automated shaping operation.

[0017] The present invention provides a device for bending and shaping the lead wire of an electric motor stator. It has the following beneficial effects:

[0018] 1. By placing the stator body at the center of the support table in the present invention, the distance between the stator body and the two shaping dies is made the same, achieving the central positioning of the stator body. Thus, during shaping, the shaping die can apply a uniform extrusion force to the coils at both ends of the stator body for shaping. Compared with the prior art, the shaping effect on the coils of the stator body is improved.

[0019] 2. When the upper mold body descends, the fixing component can be driven to automatically clamp and fix the stator body, improving the stability during the shaping of the stator body. When the mold body ascends, the fixing component automatically opens, facilitating the removal of the stator body and enhancing the operational convenience of coil shaping.

[0020] 3. The present invention realizes the end height shaping of the coil through the shaping groove, and when the wedge block rotates, the inner and outer circles of the coil end can be shaped through the arc surface and the arc side surface, thereby realizing relatively comprehensive shaping of both ends of the stator body coil.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to the attached Figure 1 - attached Figure 4, an embodiment of the present invention provides a motor stator lead wire bending and shaping device, which includes a processing table 1. A support frame 2 is fixedly connected to the upper surface of the processing table 1. U-shaped outer partitions 20 are respectively and fixedly arranged on both sides of the support frame 2. A support table is arranged inside the support frame 2. A convex placement channel is opened on the surface of the support table. The placement channel includes a large channel and a small channel. The diameter of the large channel is the same as the outer diameter of the stator body 4, and the diameter of the small channel is smaller than the outer diameter of the stator body 4 and larger than the diameter of the coil of the stator body 4, so as to provide positioning support for the stator body 4. The support table is composed of two semi-cylindrical bodies 3. One end of the semi-cylindrical body 3 is fixedly connected with an extension arm 7. One end of the extension arm 7 is rotationally connected to the inner side wall of the support frame 2 through a shaft. A support component 8 is installed on the lower side wall of the support frame 2. The support component 8 includes a sliding seat 81. One end of the sliding seat 81 is fixedly connected with the outer side wall of the support frame 2. A support plate 82 is slidably connected to the inner wall of the sliding seat 81. One end of the support plate 82 penetrates through the support frame 2 and extends below the extension arm 7. The support component 8 is used to horizontally support the extension arm 7. The stator body 4 is placed inside the placement channel. Shaping components 5 are arranged above and below the stator body 4. The shaping components 5 include two cylinders 51, the outer wall of the upper cylinder 51 is fixedly connected with the support frame 2, and the outer wall of the lower cylinder 51 is fixedly connected with the processing table 1. The driving end of the cylinder 51 is fixedly connected with a shaping die 52. The two shaping dies 52 are symmetrically distributed along the horizontal center line of the stator body 4, so that the distances between the stator body 4 and the two shaping dies 52 are the same when the stator body 4 is installed in the placement channel. The cylinder 51 is electrically connected to a controller for controlling the operation of the cylinder 51. Displacement sensors are respectively installed on the piston rods of the two cylinders 51 to detect the position of the cylinder 51 in real time and feed back the position signal to the controller. The controller adjusts the movement speed and position of the cylinder 51 by controlling the on-off of the solenoid valve according to the feedback signals of the two sensors, realizing precise control of the position of the cylinder 51.

[0034] Specifically, the placement channel is used to place the stator body 4, and the support table is used to support and position the stator body 4, so that after the stator body 4 is placed in the placement channel, its center point coincides with the center point of the distances between the two shaping dies 52. One end of the sliding plate is slid to the lower part of the extension arm 7 to provide a horizontal supporting force for it, so that the extension arm 7 and the semi-cylindrical body 3 are kept horizontal for horizontally placing the stator body 4. By pulling the sliding plate to stagger one end of it from the extension arm 7, the extension arm 7 drives the semi-plate body to rotate downward to avoid blocking the upward movement of the lower shaping die 52. The cylinder 51 is used to drive the shaping die 52 to move up and down. After the stator body 4 is installed, the two shaping dies 52 respectively abut against the upper and lower ends of the stator body 4 for bending and shaping. Since the stator body 4 is located at the center of the two shaping dies 52, the shaping dies 52 can uniformly apply pressure to both ends of the coil of the stator body 4 for shaping. Compared with the prior art, the shaping effect on the coil of the stator body 4 is improved.

[0035] Please refer to the attached Figure 4 , on the inner side wall of the sliding seat 81, a first spring 83 is fixedly connected, and the other end of the first spring 83 is fixedly connected to the outer side wall of the support plate 82. A prolonging plate 84 is fixedly connected below the support plate 82, and a bevel surface is provided at one corner of the bottom end of the prolonging plate 84.

[0036] Specifically, the first spring 83 is used to apply a driving force to the support plate 82, so that the support plate 82 can relatively stably remain below the extension arm 7 to provide support, effectively preventing the support plate 82 from being displaced from the extension arm 7 under the influence of external force when installing the stator main body 4, which may cause the stator main body 4 to fall.

[0037] Please refer to the attached Figure 3 , the support assembly 8 further includes two pushing arms 85. One ends of the two pushing arms 85 are symmetrically and fixedly connected to the outer side wall of the lower shaping die 52. A first slot is provided on the lower side wall of the support frame 2, and the first slot is used for the pushing arms 85 to pass through the support frame 2.

[0038] Specifically, when the lower shaping die 52 rises, it drives the pushing arms 85 to rise. One end of the pushing arm 85 gradually pushes open the prolonging plate 84 along the bevel surface, thereby pushing the prolonging plate 84 to slide outward. The movement of the prolonging plate 84 drives the support plate 82 to slide, and the sliding of the support plate 82 causes one end of it to be displaced from the extension arm 7, so that the extension arm 7 can automatically rotate downward when the lower shaping die 52 rises, avoiding hindering the shaping die 52 from pressing against the lower end of the stator main body 4, and realizing the automatic adjustment of the position of the support platform.

[0039] Please refer to the attached Figure 5 - attached Figure 6 , a fixing assembly 6 is installed on the outer side of the stator main body 4 and the outer side of the shaping die 52. The fixing assembly 6 includes a U-shaped fixing frame 61. Both ends of the fixing frame 61 are fixedly installed on the upper outer side wall of the support frame 2. A lead screw 62 is rotatably connected to the inner wall of the fixing frame 61. A threaded cylinder 63 is threadedly connected to the outer wall of the lead screw 62. The outer wall of the threaded cylinder 63 penetrates through the support frame 2. One end of the threaded cylinder 63 is fixedly connected to an arc-shaped clamping hand 64. A rubber layer is fixedly arranged on the inner side wall of the clamping hand 64, and the rubber layer is used to increase the friction force with the outer wall of the stator main body 4 and improve the clamping stability.

[0040] Specifically, the fixing frame 61 is used to rotatably support the lead screw 62. Rotating the lead screw 62 drives the threaded cylinder 63 to slide through the support frame 2. The sliding of the threaded cylinder 63 drives the clamping hand 64 to move, so that the clamping hand 64 can press against the outer side wall of the stator main body 4 for clamping and fixing. After the subsequent support platform rotates downward and the bottom support is cancelled, it provides lateral support for the stator main body 4 and improves the stability of the stator main body 4 during shaping.

[0041] Please refer to the attached Figure 5 - attached Figure 6The outer wall of the lead screw 62 is fixedly connected with a gear ring 65, and an L-shaped connecting arm 67 is arranged on one side of the gear ring 65. A second slot is provided on the upper side wall of the support frame 2, and the second slot is used for the connecting arm 67 to pass through the support frame 2. One end of the connecting arm 67 is fixedly connected to the outer wall of the upper shaping mold 52, and one side of the connecting arm 67 is slidably connected to the inner wall of the fixed frame 61 to improve the stability of the connecting arm 67 when sliding. A raised layer is fixedly provided on the other side of the connecting arm 67, and a plurality of equidistantly distributed tooth grooves 68 are provided on the surface of the raised layer, and the tooth grooves 68 are meshed and connected with the tooth ends of the gear ring 65.

[0042] Specifically, when the upper shaping mold 52 descends, it drives the connecting arm 67 to descend, and the descent of the connecting arm 67 drives the tooth groove 68 to descend, so that the gear ring 65 rotates, and the rotation of the gear ring 65 drives the lead screw 62 to rotate, thereby automatically applying a rotational force to the lead screw 62, and when the tooth groove 68 and the gear ring 65 are completely staggered, the lead screw 62 drives the threaded tube 63 to slide so that the clamping hand 64 is tightly against the stator body 4 for clamping and fixing, thereby achieving an automatic clamping and fixing effect on the stator body 4, and when the upper shaping mold 52 rises after the shaping is completed, the tooth groove 68 rises and drives the gear ring 65 to rotate in the opposite direction to apply a reverse rotational force to the lead screw 62, so that the two clamping hands 64 are automatically opened, so as to facilitate the removal of the stator body 4.

[0043] Please see attached Figure 7 -Attached Figure 9 A shaping groove 53 is provided on the surface of the shaping mold 52, and the side wall of the shaping groove 53 is set to an arc-shaped side surface adapted to the coil end face of the stator body 4. The shaping mold 52 includes a mold body 521 and a shell 522, one end of the shell 522 is fixedly connected to the outer wall of the mold body 521, and a driver 17 is fixedly provided on the upper surface of the upper mold body 521. A groove is provided on the inner wall of the shaping groove 53, and a rotating plate 55 is rotatably connected inside the groove. A side shaping piece 56 is installed on the outer wall of the rotating plate 55, and a driving end of the driver 17 is fixedly connected to the inner wall of the upper rotating plate 55. The controller is electrically connected to the driver 17, and the controller is used to control the operation of the driver 17.

[0044] Specifically, the shell 522 is used to connect the driving end of the cylinder 51. When the cylinder 51 is extended, it drives the mold body 521 to press against the end of the stator body 4, so that the coil end of the stator body 4 enters the inside of the shaping groove 53 for extrusion shaping, thereby realizing the end height shaping of the coil. The side shaping piece 56 cooperates with the arc-shaped side surface to shape the inner and outer circles of the coil end.

[0045] Please see attached Figure 8 -Attached Figure 10, the side shaping member 56 includes a cylinder body 561 and a rod body 562. One end of the cylinder body 561 is fixedly connected to the outer wall of the rotating plate 55. Slots are respectively formed on both sides of the cylinder body 561. One end of the rod body 562 is slidably arranged inside the cylinder body 561. A connecting member 563 is sleeved on the outer wall of the cylinder body 561. The inner wall of the connecting member 563 passes through the slots and is fixedly connected to the outer side wall of the rod body 562. A second spring 564 is fixedly connected to the inner bottom wall of the cylinder body 561. The other end of the second spring 564 is fixedly connected to one end of the rod body 562. A plurality of rotating brackets 568 are rotatably connected to the outer side wall of the connecting member 563 through a shaft. The other end of the rotating bracket 568 is rotatably connected to a wedge-shaped block 565 through a shaft. A plurality of sliding grooves 18 are formed on the surface of the rotating plate 55. One end of the wedge-shaped block 565 is slidably connected to the inner side wall of the sliding groove 18. A tension spring 19 is fixedly connected to the side wall of the wedge-shaped block 565 facing the cylinder body 561. The other end of the tension spring 19 is fixedly connected to the inner side wall of the sliding groove 18. The tension spring 19 is used to apply pressure to the wedge-shaped block 565 to facilitate the wedge-shaped block 565 to return to its original position. An arc surface adapted to the coil end of the stator body 4 is provided on one side of the wedge-shaped block 565. A plurality of connection holes 566 are formed at the top end of the lower rod body 562. A plurality of spring telescopic connecting rods 567 are embedded and connected to the bottom end of the upper rod body 562. The connection holes 566 are located on the rotation trajectory of the spring telescopic connecting rod 567. When the two rod bodies 562 are pressed against each other, the spring telescopic connecting rod 567 is compressed and contracted into the rod body 562. When the rod body 562 rotates subsequently to drive the spring telescopic connecting rod 567 to align with the connection hole 566, the spring telescopic connecting rod 567 extends and inserts into the inside of the connection hole 566, realizing the automatic connection of the two rod bodies 562.

[0046] Specifically, the second spring 564 is used to apply an elastic force to the rod body 562, so that one end of the rod body 562 extends out of the cylinder body 561. When the rod body 562 extends out of the cylinder body 561, it pulls the connecting frame to slide. The sliding of the connecting member 563 drives the rotating bracket 568 to rotate, causing the wedge block 565 to slide closer to the cylinder body 561, so that the side shaping member 56 as a whole automatically contracts, facilitating the insertion of the coil end into the shaping groove 53. When the shaping die 52 moves towards the stator body 4 and abuts against the stator body 4, the upper and lower rod bodies 562 will squeeze each other when approaching, causing the rod body 562 to contract and slide inside the cylinder body 561, causing the connecting frame to slide towards the direction close to the rotating plate 55, and driving the rotating bracket 568 to rotate. The rotation of the rotating bracket 568 pushes the wedge block 565 to move towards the coil. When the shaping die 52 abuts against the stator body 4, the rod body 562 contracts to the minimum amplitude. At this time, the arc surface abuts against the inner side wall of the coil end, realizing the automatic extension of the side shaping member 56 as a whole. Finally, the driver 17 is operated. The driver 17 drives the upper rotating plate 55 and the side shaping member 56 to rotate. When the spring telescopic link 567 rotates to the connection hole 566, the spring telescopic link 567 extends and inserts into the inside of the connection hole 566, enabling the two side shaping members 56 to rotate synchronously. When the wedge block 565 rotates, it comprehensively shapes the inner and outer sides of the coil through the cooperation of the arc surface and the arc side surface, and the frictional force applied according to the rotation direction of the wedge block 565 can drive the coil to tilt.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
