Description

Technical Field

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

[0002] The stator of the motor is composed of an iron core and a coil embedded in the inner teeth of the iron core. Since the shape of the part of the coil exposed at both ends of the iron core is irregular, it creates certain obstacles when the stator is assembled with the rotor or the casing. Therefore, the stator coil needs to be shaped before assembly, including the end height, inner ring and outer ring of the coil. The existing shaping methods are generally divided into two types. One is to perform shaping by manual hammering, and the second method is to perform internal shaping of the stator coil through an internal shaping mold or a stator shaping machine.

The present invention solves the existing problems of inconsistent dimensions after shaping due to manual shaping and easy paint loss or even breakage of the enameled wire in the stator coil. In addition, the present invention has a simple structure, is easy to repair and maintain, and is safe and easy to operate.

[0004] In the above application, when the stator is manually clamped with an arc-shaped gripper, the center point of the stator cannot be well coincident with the center point between the upper die and the lower die, so that when the upper die and the lower die move relative to each other, due to the locking of the arc-shaped gripper, one end of the stator will be subjected to excessive force, while the other end will be subjected to insufficient force, thereby affecting the shaping effect of the stator coil. In addition, when the arc-shaped gripper clamps the stator, the staff is required to hold the stator while screwing the screw and nut, which is time-consuming and labor-intensive.

[0013] Working principle: When shaping the coil of the motor stator body, the elastic driving force of spring 1 causes one end of the support plate to slide to the bottom of the extension arm, thereby horizontally supporting the extension arm and the semi-ring body, so that the support table can place the stator body in a horizontal state, and 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 mold and the distance between the lower end of the stator body and the lower shaping mold are the same, so that the center point of the stator body is automatically aligned with the center point between the two shaping molds, so that the two shaping molds can evenly press the upper and lower ends of the stator body to avoid uneven force, thereby improving the shaping effect of the stator body coil.

[0014] During shaping, the upper cylinder first extends a certain range, and the extension of the cylinder drives the upper shaping mold to descend, and the descent of the shaping mold drives the connecting arm to descend, and the descent of the connecting arm drives the tooth groove to descend until the tooth ring and the tooth groove are offset and then stop running. Through the meshing transmission of the tooth groove and the gear, the tooth ring is driven to rotate when the connecting arm descends, and the rotation of the tooth ring drives the lead screw to rotate, and the rotation of the lead screw drives the threaded barrel to slide horizontally, and the sliding of the threaded barrel drives the clamp to move toward the direction of the stator body, so that when the tooth ring and the tooth groove are offset, the clamp is tightly pressed against the stator body for clamping and fixing, thereby realizing automatic clamping of the stator body and improving the stability of the stator body during shaping.

[0015] Subsequently, the lower cylinder is also extended to a certain extent, driving the lower shaping mold to rise. The rising of the shaping mold drives the pushing arm to rise, and the pushing arm rises along the bevel surface and gradually pushes open the extension plate. The extension plate drives the support plate to slide outward, so that the support plate and the extension arm are staggered. The lack of support under the extension arm will drive the semi-ring body to rotate downward under the action of gravity, thereby causing the semi-ring body to rotate automatically, avoiding blocking the rising of the lower shaping mold to perform shaping operations on the stator main body coil. At this time, the stator main body is clamped and fixed by the fixing assembly, and the stability of the stator main body will not be affected in the absence of semi-ring body support.

[0016] Then the two cylinders continue to extend synchronously, so that the upper and lower shaping molds are respectively against the two ends of the stator body, so that the two ends of the coil of the stator body enter the shaping groove for end height shaping respectively, and when the shaping mold is against the stator body, the two rods will be against each other, thereby producing contraction and sliding inside the cylinder respectively, and when the rod slides in the cylinder, it will drive the connecting piece to move in the direction of the rotating plate, and the movement of the connecting piece drives the rotating bracket to rotate, thereby pushing the wedge block to slide and unfold, so that the arc surface of the wedge block is against the inner side of the end of the stator body coil, and the arc side of the shaping groove will fit the outer side of the end of the stator body coil. At this time, the driver is run, and the upper rotating plate and the side shaping piece are driven to rotate by the driver, and the spring telescopic connecting rod is automatically inserted when it rotates to align with the connecting hole, thereby automatically connecting the two connecting rods, so that a single set of drivers can simultaneously drive the two side shaping pieces to shape the upper and lower ends of the stator body coil, and the wedge block is driven to rotate by the driver, so that the coil of the stator body completes the shaping of the inner and outer circles of a whole circle, thereby realizing automated shaping operation.

[0017] The present invention provides a device for bending and shaping the stator lead wires of a motor. It has the following beneficial effects: 1. The present invention places the stator body at the center of the support platform so that the distance between the stator body and the two shaping molds is the same, thereby realizing the center positioning of the stator body. Therefore, during shaping, the shaping mold can apply uniform extrusion force to the coils at both ends of the stator body for shaping. Compared with the prior art, the shaping effect of the stator body coil is improved.

[0018] 2. The present invention can automatically clamp and fix the stator body by driving the fixing assembly when the upper mold body descends, thereby improving the stability of the stator body during shaping. When the mold body rises, the fixing assembly automatically opens to facilitate the removal of the stator body, thereby improving the convenience of coil shaping operation.

[0019] 3. The present invention realizes the end height shaping of the coil through the shaping groove, and can shape the inner and outer circles of the coil end through the arc surface and the arc side surface when the wedge block rotates, thereby realizing relatively comprehensive shaping of both ends of the stator main body coil.

The spacing between the two shaping molds 52 is the same, the cylinder 51 is electrically connected to a controller for controlling the operation of the cylinder 51, and 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 and off of the solenoid valve according to the feedback signals of the two sensors, thereby realizing precise control of the position of the cylinder 51.

[0024] 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 distance between the two shaping molds 52, and one end of the sliding plate is slid to the bottom of the extension arm 7 to provide it with horizontal support force, so that the extension arm 7 and the semi-ring body 3 remain horizontal, which is used to horizontally place the stator body 4, and by pulling the sliding plate so that one end is staggered with the extension arm 7, the extension arm 7 drives the semi-plate body to rotate downward to avoid blocking the rise of the shaping mold 52 below, and the cylinder 51 is used to drive the shaping mold 52 to rise and fall. After the stator body 4 is installed, the two shaping molds 52 are respectively pressed 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 molds 52, the shaping mold 52 can evenly apply pressure to both ends of the coil of the stator body 4 for shaping.

[0025] Please refer to the attached Figure 4 The inner wall of the sliding seat 81 is fixedly connected with a spring 83, and the other end of the spring 83 is fixedly connected with the outer wall of the support plate 82. An extension plate 84 is fixedly connected below the support plate 82, and a corner of the bottom end of the extension plate 84 is provided with a chamfered surface.

[0026] Specifically, spring 1 83 is used to apply a driving force to the support plate 82, so that the support plate 82 can be relatively stably maintained under the extension arm 7 to provide support, effectively preventing the support plate 82 from being affected by external forces and being offset from the extension arm 7 when the stator body 4 is installed, causing the stator body 4 to fall.

[0027] Please refer to the attached Figure 3 The support assembly 8 also includes two push arms 85, one end of the two push arms 85 is symmetrically fixedly connected to the outer side wall of the lower shaping mold 52, and a slot 1 is formed on the lower side wall of the support frame 2, and the slot 1 is used for the push arms 85 to pass through the support frame 2.

[0028] Specifically, when the lower shaping mold 52 rises, the pushing arm 85 is driven to rise, and one end of the pushing arm 85 gradually pushes open the extension plate 84 along the cutting slope, thereby pushing the extension plate 84 to slide outward, and the movement of the extension plate 84 drives the support plate 82 to slide, and the support plate 82 slides so that one end of the support plate is staggered with the extension arm 7, so that the extension arm 7 can automatically rotate downward when the lower shaping mold 52 rises, avoiding obstruction to the shaping mold 52 against the lower end of the stator body 4, thereby realizing automatic adjustment of the support platform position.

[0029] Please refer to the attached Figure 5 -Attached Figure 6A fixing assembly 6 is installed on the outer side of the stator body 4 and the outer side of the shaping mold 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 wall of the support frame 2. The inner wall of the fixing frame 61 is rotatably connected with a lead screw 62. The outer wall of the lead screw 62 is threadedly connected with a threaded cylinder 63. The outer wall of the threaded cylinder 63 passes through the support frame 2. One end of the threaded cylinder 63 is fixedly connected with an arc-shaped clamping hand 64. The inner side wall of the clamping hand 64 is fixedly provided with a rubber layer. The rubber layer is used to increase the friction with the outer wall of the stator body 4 and improve the clamping stability.

[0030] Specifically, the fixing frame 61 is used to rotate the supporting screw 62. The rotating screw 62 drives the threaded tube 63 to slide through the supporting frame 2. The sliding of the threaded tube 63 drives the clamping hand 64 to move, so that the clamping hand 64 can be pressed against the outer wall of the stator body 4 for clamping and fixing. After the support platform is rotated downward and the bottom support is cancelled, lateral support is provided for the stator body 4, thereby improving the stability of the stator body 4 during shaping.

[0031] Please see attached Figure 5 -Attached Figure 6 The 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.

[0032] 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.

[0033] Please see attached Figure 7 -Attached Fig. 9A 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.

[0034] 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.

[0035] Please see attached Figure 8 -Attached Fig.10 The side shaping member 56 includes a cylinder 561 and a rod 562, one end of the cylinder 561 is fixedly connected to the outer wall of the rotating plate 55, and grooves are respectively provided on both sides of the cylinder 561. One end of the rod 562 is slidably arranged inside the cylinder 561, and a connecting member 563 is sleeved on the outer wall of the cylinder 561. The inner wall of the connecting member 563 passes through the groove and is fixedly connected to the outer wall of the rod 562. A spring 2 564 is fixedly connected to the inner bottom wall of the cylinder 561, and the other end of the spring 2 564 is fixedly connected to one end of the rod 562. The outer wall of the connecting member 563 is rotatably connected to a plurality of rotating brackets 568 through an axis, and the other end of the rotating bracket 568 is rotatably connected to a wedge block 565 through an axis. A plurality of slide grooves 18 are provided on the surface of the rotating plate 55, and one end of the wedge block 565 is slidably connected to the inner wall of the slide groove 18, and the wedge block 565 faces the cylinder A tension spring 19 is fixedly connected to the side wall of 561, and the other end of the tension spring 19 is fixedly connected to the inner wall of the slide groove 18. The tension spring 19 is used to apply pressure to the wedge block 565 to facilitate the wedge block 565 to return to its original position. One side of the wedge block 565 is provided with an arc surface adapted to the coil end of the stator body 4. A plurality of connecting holes 566 are provided at the top of the lower rod body 562, and a plurality of spring telescopic connecting rods 567 are embedded and connected to the bottom end of the upper rod body 562. The connecting hole 566 is located on the rotation trajectory of the spring telescopic connecting rod 567. When the two rod bodies 562 are squeezed against each other, the spring telescopic connecting rod 567 is squeezed and contracted into the rod body 562. When the subsequent rotation of the rod body 562 drives the spring telescopic connecting rod 567 to align with the connecting hole 566, the spring telescopic connecting rod 567 stretches and is inserted into the inside of the connecting hole 566, thereby realizing the automatic connection of the two rod bodies 562.

[0036] Specifically, the second spring 564 is used to apply elastic force to the rod 562, so that one end of the rod 562 extends out of the cylinder 561, and when the rod 562 extends out of the cylinder 561, it pulls the connecting frame to slide, and the connecting member 563 slides to drive the rotating bracket 568 to rotate, so that the wedge block 565 slides close to the cylinder 561, so that the side shaping member 56 automatically shrinks as a whole, which is convenient for the coil end to be inserted into the shaping groove 53. When the shaping mold 52 moves toward the stator body 4 and abuts against the stator body 4, the upper and lower rods 562 will squeeze each other after approaching, so that the rod 562 shrinks and slides inside the cylinder 561, so that the connecting frame slides in the direction close to the rotating plate 55, and drives the rotating bracket 568 to rotate, and the rotating bracket 568 rotates to push the wedge block 565 to move in the direction of the coil, until the shaping mold 52 abuts against the stator body 4, the rod 562 shrinks to the minimum amplitude, at which 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, and the driver 17 drives the upper rotating plate 55 and the side shaping piece 56 to rotate, so that when the spring telescopic link 567 rotates to the connecting hole 566, the spring telescopic link 567 stretches and inserts into the inside of the connecting hole 566, so that the two side shaping pieces 56 can realize synchronous rotation, and when the wedge block 565 rotates, the inner and outer sides of the coil are comprehensively shaped through the cooperation of the arc surface and the arc side surface, and the friction force applied according to the rotation direction of the wedge block 565 can drive the coil to tilt.
