Description

Technical Field

[0001] The present invention relates to the technical field of motor stator-rotor assembly technology, and specifically relates to an assembly tooling for motor stators and rotors. Background Art

[0002] For a stator and rotor, the fixed part in a motor is called the stator, on which pairs of stationary main magnetic poles with direct current excitation are installed; while the rotating part, the rotor, is called the armature core, on which an armature winding is to be installed. After being energized, it generates an induced electromotive force, acting as a rotating magnetic field, and then generates an electromagnetic torque for energy conversion. Classified by the shape and embedding method of the stator winding, according to the different shapes of the coil winding and the embedding wiring methods, the stator winding can be divided into two categories: concentrated type and distributed type.

[0003] After the motor stator and rotor are produced, they need to be aligned for assembly. During assembly, special attention needs to be paid to whether the positions of the rotor and the stator are centered and there should be no deviation. Currently, when some assembly toolings specifically for motor stators and rotors are in use, they can only process a single set of stators and rotors. After one set is assembled, another set of stators and rotors can be put in for assembly work. And when placing the rotor on the assembly tooling, the staff needs to pay special attention to ensure that the rotor is in a centered state. During large-scale assembly work, the assembly efficiency is low. For this reason, we propose an assembly tooling for motor stators and rotors. Summary of the Invention

[0004] The purpose of the present invention is to provide an assembly tooling for motor stators and rotors to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An assembly tooling for motor stators and rotors, comprising:

[0007] An assembly table;

[0008] A hydraulic device arranged on the top of the assembly table for assisting assembly;

[0009] A supporting mechanism arranged on the top of the assembly table for supporting the stator and rotor;

[0010] The supporting mechanism is composed of a base, a main shaft, a rotor bracket and a stator bracket. A positioning component for centering and fixing the rotor is arranged on the rotor bracket, and a driven component for controlling the rotation of the main shaft is arranged on the top of the base.

[0011] Preferably, the positioning assembly includes a turntable, which is rotatably mounted on the bottom of the rotor bracket, an arc-shaped groove is provided on the top of the turntable, a guide groove is provided on the rotor bracket, a positioning frame is slidably mounted on the inner side of the guide groove, the bottom of the positioning frame is plugged into the inner side of the arc-shaped groove, an annular gear is fixed on the surface of the turntable, a slide groove is provided at the bottom of the rotor bracket, a control rack is slidably mounted on the inner side of the slide groove, the control rack is meshed with the annular gear, a return spring is fixed on the side of the control rack close to the main shaft, and one end of the return spring away from the control rack is fixed on the inner side of the slide groove. When assembling the stator and rotor, first assemble the stator It is placed on the stator bracket. When the control rack is pushed to move to the side close to the main shaft, the annular gear meshing with the control rack drives the turntable to rotate. Since the positioning frame is limited by the guide groove on the rotor bracket, the turntable can contact the positioning frame through the arc groove opened on its top when rotating, so that the positioning frame moves and the rotor passes through the rotor bracket. At this time, you only need to loosen the control rack. Under the action of the reset spring, the control rack is reset, and the control rack drives the annular gear to rotate in the opposite direction. The annular gear drives the turntable to rotate, thereby controlling the positioning frame to move to the side close to the rotor. While fixing the rotor, it can ensure that the rotor is in a centered position and aligned with the stator, which is easy to operate.

[0012] Preferably, a rubber pad is fixed to one side of the positioning frame close to the center of the rotor bracket. When the positioning frame positions and fixes the rotor, the rubber pad can protect the rotor without affecting the fixing effect.

[0013] Preferably, a through groove is provided on the surface of the main shaft to allow the rotor bracket to move up and down.

[0014] The top of the stator bracket is fixed with an end portion which is away from the sliding rod and an end portion which is away from the sliding rod and is slidably connected to the sliding rod.

[0015] Preferably, a ratchet pawl is provided on the surface of the rotating rod, and a ratchet wheel is provided on the inner wall of the main shaft. When the sliding rod slides upward along the spiral groove on the surface of the rotating rod, the rotating rod rotates. At this time, the rotating rod rotates clockwise, and the ratchet pawl on the surface of the rotating rod can be stuck on the ratchet wheel on the inner wall of the main shaft, thereby driving the main shaft to rotate together. When the sliding rod slides downward along the spiral groove on the surface of the rotating rod, the rotating rod rotates counterclockwise at this time, and the ratchet pawl on the surface of the rotating rod cannot be stuck on the ratchet wheel on the inner wall of the main shaft, so the main shaft cannot be driven to rotate.

[0016] Preferably, the base is fixed on the top of the assembly table. The top of the base is rotatably connected to the bottom of the main shaft. The main shaft penetrates through the stator bracket and is fixedly connected to the stator bracket. The rotor bracket is slidably installed in the through groove on the surface of the main shaft. A tension spring is fixed to the top of the rotor bracket. The end of the tension spring away from the rotor bracket is fixed to the inner side of the through groove. By placing the stator on the stator bracket and the rotor on the rotor bracket, when starting the hydraulic equipment to assemble the stator and rotor, the hydraulic equipment abuts against the rotor, pushing the rotor and the rotor bracket downward. The rotor is limited by the positioning component to ensure that the rotor can be stably inserted into the stator. When the hydraulic equipment is controlled to reset, the rotor bracket can move upward and reset under the action of the tension spring.

[0017] Preferably, a limiting component is provided on the inner side of the positioning hole, the inner side of the through groove and the sliding rod. The limiting component includes an L-shaped clamping rod. The L-shaped clamping rod penetrates through the sliding rod and is slidably connected to the sliding rod. A first spring is fixed to the bottom of the L-shaped clamping rod. The end of the first spring away from the L-shaped clamping rod is fixed to the inner wall of the sliding rod. A connecting rod is fixed to the top of the L-shaped clamping rod. The connecting rod penetrates through the top of the sliding rod and is slidably connected to the sliding rod. A clamping groove is provided on the inner side of the positioning hole. A connecting plate is fixed to the top of the connecting rod. A fixing plate is fixed to the inner side of the through groove. When the triangular block at the bottom of the control rack is abutted by the abutting rod and the control rack is pushed to move toward the side close to the main shaft, when the sliding rod is inserted into the positioning hole, the sliding rod drives the L-shaped clamping rod to be inserted together. The L-shaped clamping rod is clamped into the clamping groove on the inner side of the positioning hole, thereby limiting the control rack. When the control rack drives the sliding rod to move upward for a certain distance, the connecting plate is abutted by the fixing plate, and the connecting plate drives the connecting rod and the L-shaped clamping rod to move downward in a deformed manner. The L-shaped clamping rod withdraws from the clamping groove on the inner side of the positioning hole, thereby releasing the limit on the control rack. Under the action of the return spring, the control rack moves toward the side away from the main shaft, and the sliding rod withdraws from the positioning hole, so the sliding rod moves downward and resets under the action of the connecting spring.

[0018] Compared with the prior art, the present invention provides an assembly tooling for a motor stator and rotor, which has the following beneficial effects:

[0019] 1. After placing the four unassembled stators and rotors on the corresponding rotor brackets and stator brackets respectively through the set supporting mechanism, positioning component and driven component, start the hydraulic equipment to assemble one set of stators and rotors. After one set is assembled, the main shaft can automatically rotate 90°, so that another set of unassembled stators and rotors rotates under the hydraulic equipment, and the assembly work can be directly carried out. The staff only needs to remove the assembled stators and rotors and then place the unassembled ones. During large-batch assembly operations, the work efficiency can be effectively improved.

[0020] 2. Through the set positioning component, the control rack is pushed to move towards the side close to the main shaft. The annular gear meshing with the control rack drives the turntable to rotate. Since the positioning frame is limited by the guide groove on the rotor bracket, when the turntable rotates, it can contact the positioning frame through the arc groove opened on its top, causing the positioning frame to move. Pass the rotor through the rotor bracket. At this time, just loosen the control rack. Under the action of the return spring, the control rack resets. The control rack drives the annular gear to rotate in the opposite direction, and the annular gear drives the turntable to rotate, thereby controlling the positioning frame to move towards the side close to the rotor. While fixing the rotor, it can ensure that the rotor is in the centered position and aligned with the stator. The operation is convenient and the assembly efficiency is effectively improved.

[0021] 3. When the slide bar slides upward along the spiral groove on the surface of the rotating rod, the rotating rod rotates. At this time, the rotating rod rotates clockwise. The pawl on the surface of the rotating rod can be stuck on the ratchet on the inner wall of the main shaft, thereby driving the main shaft to rotate together. When the slide bar slides downward along the spiral groove on the surface of the rotating rod, at this time the rotating rod rotates counterclockwise, and the pawl on the surface of the rotating rod cannot be stuck on the ratchet on the inner wall of the main shaft, so it cannot drive the main shaft to rotate. It can effectively avoid the reverse rotation of the main shaft after a set of stators and rotors are assembled. And through the automatic rotation of the main shaft, there is no need for manual operation by the staff, which improves the assembly efficiency to a certain extent. Description of the Drawings

DETAILED DESCRIPTION

[0032] like Figures 1-9 As shown, the present invention provides a technical solution: an assembly tool for a motor stator and rotor, comprising an assembly table 1, a hydraulic device 2 for assisting assembly is arranged on the top of the assembly table 1, a supporting mechanism 6 for supporting the stator and rotor is arranged on the top of the assembly table 1, the supporting mechanism 6 is composed of a base 61, a main shaft 62, a rotor bracket 63 and a stator bracket 64, a positioning component 3 for centering and fixing the rotor is arranged on the rotor bracket 63, and a driven component 4 for controlling the rotation of the main shaft 62 is arranged on the top of the base 61.

[0033] The positioning component 3 includes a turntable 31 which is rotatably installed at the bottom of the rotor bracket 63. An arc-shaped groove 32 is formed at the top of the turntable 31. A guiding groove 33 is formed on the rotor bracket 63. A positioning frame 34 is slidably installed inside the guiding groove 33. The bottom of the positioning frame 34 is inserted inside the arc-shaped groove 32. A ring gear 35 is fixed on the surface of the turntable 31. A sliding groove 36 is formed at the bottom of the rotor bracket 63. A control rack 37 is slidably installed inside the sliding groove 36. The control rack 37 meshes with the ring gear 35. A return spring 38 is fixed on the side of the control rack 37 close to the main shaft 62. The end of the return spring 38 away from the control rack 37 is fixed inside the sliding groove 36. When assembling the stator and rotor, first place the stator on the stator bracket 64. When the control rack 37 is pushed to move towards the side close to the main shaft 62, the ring gear 35 meshing with the control rack 37 drives the turntable 31 to rotate. Since the positioning frame 34 is limited by the guiding groove 33 on the rotor bracket 63, when the turntable 31 rotates, it can contact the positioning frame 34 through the arc-shaped groove 32 formed at its top, causing the positioning frame 34 to move. Pass the rotor through the rotor bracket 63. At this time, just release the control rack 37. Under the action of the return spring 38, the control rack 37 returns to its original position. The control rack 37 drives the ring gear 35 to rotate in the opposite direction, and the ring gear 35 drives the turntable 31 to rotate, thereby controlling the positioning frame 34 to move towards the side close to the rotor. While fixing the rotor, it can ensure that the rotor is centered and aligned with the stator, and the operation is convenient.

[0034] A rubber pad 7 is fixed on the side of the positioning frame 34 close to the center of the rotor bracket 63. When the positioning frame 34 positions and fixes the rotor, through the arranged rubber pad 7, it can play a role in protecting the rotor while not affecting the fixing effect.

[0035] A through groove 8 is formed on the surface of the main shaft 62, which allows the rotor bracket 63 to move up and down.

[0036] The driven assembly 4 includes a triangular block 41, which is fixed at the bottom of the control rack 37. A rotating rod 42 is rotatably installed on the top of the base 61. A spiral groove 43 is provided on the surface of the rotating rod 42. A sliding rod 44 is slidably installed on the inner side of the spiral groove 43. The sliding rod 44 passes through the through groove 8 on the surface of the main shaft 62 and is slidably connected with the through groove 8. A connecting spring 45 is fixed at the bottom of the sliding rod 44. One end of the connecting spring 45 away from the sliding rod 44 is fixed on the inner side of the through groove 8. A resisting rod 46 is fixed on the top of the stator bracket 64. A locking hole 47 is provided on the side of the control rack 37 close to the main shaft 62. When the rotor bracket 63 drives the control rack 37 to move downward a certain distance, the triangular block 41 at the bottom of the control rack 37 is resisted by the resisting rod 46, pushing the control rack 37 to move to the side close to the main shaft 62. When the control positioning frame 34 releases the fixation on the rotor, the slide bar 44 is inserted into the locking hole 47. Then, when the rotor bracket 63 moves upward, the rotor bracket 63 drives the control rack 37 to reset upward together. The control rack 37 can drive the slide bar 44 to move upward together. The slide bar 44 slides along the spiral groove 43 on the surface of the rotating rod 42, so that the rotating rod 42 rotates 90°.

[0037] A pawl 9 is provided on the surface of the rotating rod 42, and a ratchet 10 is provided on the inner wall of the main shaft 62. When the sliding rod 44 slides upward along the spiral groove 43 on the surface of the rotating rod 42, the rotating rod 42 rotates. At this time, the rotating rod 42 rotates clockwise, and the pawl 9 on the surface of the rotating rod 42 can be stuck on the ratchet 10 on the inner wall of the main shaft 62, thereby driving the main shaft 62 to rotate together. When the sliding rod 44 slides downward along the spiral groove 43 on the surface of the rotating rod 42, the rotating rod 42 rotates counterclockwise, and the pawl 9 on the surface of the rotating rod 42 cannot be stuck on the ratchet 10 on the inner wall of the main shaft 62, thereby failing to drive the main shaft 62 to rotate.

[0038] The base 61 is fixed on the top of the assembly table 1, and the top of the base 61 is rotatably connected to the bottom of the main shaft 62. The main shaft 62 passes through the stator bracket 64 and is fixedly connected to the stator bracket 64. The rotor bracket 63 is slidably installed in the through groove 8 on the surface of the main shaft 62. A tension spring 11 is fixed on the top of the rotor bracket 63, and one end of the tension spring 11 away from the rotor bracket 63 is fixed to the inner side of the through groove 8. By placing the stator on the stator bracket 64 and the rotor on the rotor bracket 63, when the hydraulic equipment 2 is started to assemble the stator and rotor, the hydraulic equipment 2 contacts the rotor and pushes the rotor and the rotor bracket 63 to move downward. The rotor is limited by the positioning assembly 3 to ensure that the rotor can be stably rotated into the stator. When the hydraulic equipment 2 is controlled to be reset, the rotor bracket 63 can be moved upward and reset under the action of the tension spring 11.

[0039] A limiting component 5 is arranged on the inner side of the clamping hole 47, the inner side of the through groove 8 and the sliding rod 44. The limiting component 5 includes an L-shaped clamping rod 51. The L-shaped clamping rod 51 penetrates through the sliding rod 44 and is slidably connected with the sliding rod 44. A first spring 52 is fixed to the bottom of the L-shaped clamping rod 51. One end of the first spring 52 away from the L-shaped clamping rod 51 is fixed to the inner wall of the sliding rod 44. A connecting rod 53 is fixed to the top of the L-shaped clamping rod 51. The connecting rod 53 penetrates through the top of the sliding rod 44 and is slidably connected with the sliding rod 44. A clamping groove 54 is formed on the inner side of the clamping hole 47. A connecting plate 55 is fixed to the top of the connecting rod 53. A fixing plate 56 is fixed to the inner side of the through groove 8. When the triangular block 41 at the bottom of the control rack 37 is abutted by the abutting rod 46 and the control rack 37 is pushed to move towards the side close to the main shaft 62, and when the sliding rod 44 is inserted into the clamping hole 47, the sliding rod 44 drives the L-shaped clamping rod 51 to be inserted together. The L-shaped clamping rod 51 is clamped into the clamping groove 54 on the inner side of the clamping hole 47, so as to limit the control rack 37. When the control rack 37 drives the sliding rod 44 to move upwards for a certain distance, the connecting plate 55 is abutted by the fixing plate 56. The connecting plate 55 drives the connecting rod 53 and the L-shaped clamping rod 51 to move downwards in a disguised form. The L-shaped clamping rod 51 withdraws from the clamping groove 54 on the inner side of the clamping hole 47, so as to release the limit on the control rack 37. Under the action of the return spring 38, the control rack 37 moves towards the side away from the main shaft 62, and the sliding rod 44 withdraws from the clamping hole 47. Thus, the sliding rod 44 moves downwards to reset under the action of the connecting spring 45.

[0040] Based on the above embodiments, first, prepare four sets of stators and rotors to be assembled. Place the stator on the stator bracket 64, take the rotor, and push the control rack 37 to move towards the side close to the main shaft 62. The annular gear 35 meshing with the control rack 37 drives the turntable 31 to rotate. Since the positioning frame 34 is limited by the guiding groove 33 on the rotor bracket 63, when the turntable 31 rotates, it can abut against the positioning frame 34 through the arc groove 32 formed on its top, so that the positioning frame 34 moves. Pass the rotor through the rotor bracket 63. At this time, just loosen the control rack 37. Under the action of the return spring 38, the control rack 37 resets. The control rack 37 drives the annular gear 35 to rotate in the opposite direction. The annular gear 35 drives the turntable 31 to rotate, so as to control the positioning frame 34 to move towards the side close to the rotor. While fixing the rotor, it can ensure that the rotor is in the centered position and aligned with the stator, which is convenient to operate.

[0041] At this time, start the hydraulic device 2 to perform the assembly work on one set of stators and rotors. The hydraulic device 2 abuts against the rotor and pushes the rotor and the rotor bracket 63 to move downwards. When the rotor contacts the stator and the assembly is completed, the abutting rod 46 abuts against the triangular block 41 at the bottom of the control rack 37 and pushes the control rack 37 to move towards the side close to the main shaft 62. The sliding rod 44 is inserted into the clamping hole 47, and at the same time, the L-shaped clamping rod 51 is clamped into the clamping groove 54 on the inner side of the clamping hole 47, so as to limit the control rack 37.

[0042] At this time, since the control rack 37 moves towards the side close to the main shaft 62, the positioning frame 34 releases the positioning and fixing of the rotor, and the hydraulic device 2 continues to press the rotor downward, thus completing the assembly of the rotor.

[0043] After the assembly is completed, the control hydraulic device 2 moves upward to reset. At this time, the rotor bracket 63 is no longer pushed downward. Under the action of the tension spring 11, the rotor bracket 63 drives the control rack 37 to move upward. The control rack 37 drives the slide bar 44 to move upward. The slide bar 44 slides upward along the spiral groove 43 on the surface of the rotating rod 42, so that the rotating rod 42 rotates clockwise by 90°. At this time, the pawl 9 on the surface of the rotating rod 42 is stuck on the ratchet 10 on the inner wall of the main shaft 62, driving the main shaft 62 to rotate clockwise by 90° together, so that the other set of unfitted stator and rotor rotates to the bottom of the hydraulic device 2.

[0044] When the slide bar 44 moves upward a certain distance following the control rack 37, the connecting plate 55 is resisted by the fixing plate 56. The connecting plate 55 drives the connecting rod 53 and the L-shaped clamping rod 51 to move downward in a disguised form. The L-shaped clamping rod 51 withdraws from the clamping groove 54 inside the clamping hole 47, thus releasing the limit on the control rack 37. Under the action of the return spring 38, the control rack 37 moves towards the side away from the main shaft 62, and the slide bar 44 withdraws from the clamping hole 47. Thus, the slide bar 44 moves downward to reset under the action of the connecting spring 45. When the slide bar 44 slides downward along the spiral groove 43 on the surface of the rotating rod 42, the rotating rod 42 rotates counterclockwise, and the pawl 9 on the surface of the rotating rod 42 cannot be stuck on the ratchet 10 on the inner wall of the main shaft 62, so the main shaft 62 cannot be driven to rotate.

[0045] At this time, it is only necessary to continue placing the unfitted stator and rotor on the stator bracket 64 and the rotor bracket 63, and the assembly work can be carried out continuously, effectively improving the overall work efficiency.

[0046] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
