Description

Technical Field

[0001] The invention relates to the technical field of motor stator and rotor assembly, in particular to an assembly tool for a motor stator and rotor. Background Art

[0002] The fixed part of the motor is called the stator, on which a pair of static main magnetic poles with DC excitation are installed; the rotating part, the rotor, is called the armature core, on which the armature winding is installed. When energized, it generates an induced electromotive force, which acts as a rotating magnetic field. Then it generates electromagnetic torque for energy conversion. The stator winding can be divided into two types: centralized and distributed, depending on the shape and embedding method of the stator winding.

[0003] After the motor stator and rotor are produced, they need to be aligned for assembly. During assembly, special attention should be paid to whether the positions of the rotor and stator are centered and no offset should occur. Currently, some assembly tools specifically used for motor stators and rotors can only process a single set of stators and rotors when in use. After one set of assembly is completed, another set of stators and rotors can be placed for assembly. When placing the rotor on the assembly tool, 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 tool for motor stators and rotors. Summary of the invention

[0004] The object of the present invention is to provide an assembly tool for a motor stator and rotor to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: An assembly tool for a motor stator and rotor, comprising: Assembly table; A hydraulic device arranged on the top of the assembly table for assisting assembly; A supporting mechanism disposed on the top of the assembly platform for supporting the stator and rotor; 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.

[0006] 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.

[0007] 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.

[0008] Preferably, a through groove is provided on the surface of the main shaft to allow the rotor bracket to move up and down.

[0009] 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.

[0010] Preferably, a pawl is provided on the surface of the rotating rod, and a ratchet 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, and 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 sliding rod slides downward along the spiral groove on the surface of the rotating rod, 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, thereby failing to drive the main shaft to rotate.

[0011] 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 passes 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, and a tension spring is fixed on the top of the rotor bracket, and 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 the hydraulic equipment is started to assemble the stator and rotor, the hydraulic equipment contacts the rotor and pushes the rotor and the rotor bracket to move downward. The rotor is limited by the positioning assembly to ensure that the rotor can be stably rotated 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.

[0012] Preferably, a limit assembly is arranged on the inner side of the positioning hole, the inner side of the through slot and the slide bar, and the limit assembly includes an L-shaped clamping rod, the L-shaped clamping rod passes through the slide bar and is slidably connected to the slide bar, a spring 1 is fixed to the bottom of the L-shaped clamping rod, and one end of the spring 1 away from the L-shaped clamping rod is fixed to the inner wall of the slide bar, a connecting rod is fixed to the top of the L-shaped clamping rod, and the connecting rod passes through the top of the slide bar and is slidably connected to the slide bar, a clamping groove is opened on the inner side of the positioning hole, a connecting plate is fixed on the top of the connecting rod, and a fixing plate is fixed on the inner side of the through slot. When the triangular block at the bottom of the control rack is resisted by the resisting rod, it pushes The control rack moves to the side close to the main shaft. When the slide bar is inserted into the positioning hole, the slide bar is inserted together with the L-shaped clamping rod, and 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 moves upward with the slide bar for a distance, the connecting plate is resisted by the fixed plate, and the connecting plate moves downward with the connecting rod and the L-shaped clamping rod in disguise, and 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 reset spring, the control rack moves to the side away from the main shaft, and the slide bar withdraws from the positioning hole, so that the slide bar moves downward and resets under the action of the connecting spring.

[0013] Compared with the prior art, the present invention provides an assembly tool for a motor stator and rotor, which has the following beneficial effects: 1. Through the support mechanism, positioning assembly and driven assembly, after placing four groups of unassembled stators and rotors on the corresponding rotor bracket and stator bracket respectively, start the hydraulic equipment to assemble one group of stators and rotors. After one group of assembly is completed, the main shaft can automatically rotate 90°, so that the other group of unassembled stators and rotors can be rotated under the hydraulic equipment, and the assembly work can be carried out directly. The staff only needs to remove the assembled stators and rotors and place the unassembled stators and rotors. In the case of large-scale assembly operations, the work efficiency can be effectively improved.

[0014] 2. Through the positioning assembly, the control rack is pushed to move to the side close to the main shaft, and 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, so that the positioning frame moves and the rotor passes through the rotor bracket. At this time, it is only necessary 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 the center and aligned with the stator. The operation is convenient and the assembly efficiency is effectively improved.

[0015] 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, and the pawl on the surface of the rotating rod can be stuck on the ratchet on the inner wall of the spindle, thereby driving the spindle to rotate together. When the slide bar slides downward along the spiral groove on the surface of the rotating rod, the rotating rod rotates counterclockwise. The pawl on the surface of the rotating rod cannot be stuck on the ratchet on the inner wall of the spindle, thereby failing to drive the spindle to rotate. This can effectively prevent the spindle from rotating in the opposite direction after a set of stators and rotors are assembled. In addition, the automatic rotation of the spindle eliminates the need for manual operation by the staff, thereby improving the assembly efficiency to a certain extent.

DETAILED DESCRIPTION

[0018] like Figure 1-Figure 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.

[0019] The positioning assembly 3 includes a turntable 31, which is rotatably mounted at the bottom of the rotor bracket 63. An arc groove 32 is provided at the top of the turntable 31, and a guide groove 33 is provided on the rotor bracket 63. A positioning frame 34 is slidably mounted on the inner side of the guide groove 33. The bottom of the positioning frame 34 is inserted into the inner side of the arc groove 32. An annular gear 35 is fixed to the surface of the turntable 31. A slide groove 36 is provided at the bottom of the rotor bracket 63. A control rack 37 is slidably mounted on the inner side of the slide groove 36. The control rack 37 is meshed with the annular 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 to the inner side of the slide groove 36. When assembling the stator and rotor, the stator is first placed on the stator bracket 64. When the control rack 37 is pushed to move toward 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 guide groove 33 on the rotor bracket 63, when the turntable 31 rotates, the arc groove 32 opened on the top of the turntable 31 can contact the positioning frame 34, so that the positioning frame 34 moves and the rotor passes through the rotor bracket 63. At this time, it is only necessary to loosen the control rack 37. Under the action of the reset spring 38, the control rack 37 is reset, and 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, thereby controlling the positioning frame 34 to move toward 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.

[0020] A rubber pad 7 is fixed to one 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, the rubber pad 7 can protect the rotor without affecting the fixing effect.

[0021] A through slot 8 is formed on the surface of the main shaft 62 to allow the rotor bracket 63 to move up and down.

[0022] 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°.

[0023] 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.

[0024] 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.

[0025] A limit assembly 5 is provided on the inner side of the positioning hole 47, the inner side of the through slot 8 and the slide bar 44. The limit assembly 5 includes an L-shaped clamping rod 51, which passes through the slide bar 44 and is slidably connected to the slide bar 44. A spring 52 is fixed to the bottom of the L-shaped clamping rod 51, and one end of the spring 52 away from the L-shaped clamping rod 51 is fixed to the inner wall of the slide bar 44. A connecting rod 53 is fixed to the top of the L-shaped clamping rod 51, and the connecting rod 53 passes through the top of the slide bar 44 and is slidably connected to the slide bar 44. A clamping groove 54 is provided on the inner side of the positioning hole 47, a connecting plate 55 is fixed to the top of the connecting rod 53, and a fixing plate 56 is fixed to the inner side of the through slot 8. When the triangular block 41 at the bottom of the control rack 37 is resisted by the resisting rod 46, the control rack 37 is pushed to approach the main shaft 62. When the control rack 37 moves upward with the slide bar 44 for a certain distance, the connecting plate 55 is abutted by the fixed plate 56, and the connecting plate 55 in disguised form brings the connecting rod 53 and the L-shaped connecting rod 51 downward, and the L-shaped connecting rod 51 withdraws from the groove 54 on the inner side of the locking hole 47, thereby releasing the limit on the control rack 37. Under the action of the reset spring 38, the control rack 37 moves to the side away from the main shaft 62, and the slide bar 44 withdraws from the locking hole 47, so that the slide bar 44 moves downward and resets under the action of the connecting spring 45.

[0026] Based on the above embodiment, first, four sets of stators and rotors to be assembled are prepared, the stators are placed on the stator bracket 64, the rotor is taken, and the control rack 37 is pushed to move to 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 guide groove 33 on the rotor bracket 63, when the turntable 31 rotates, the arc groove 32 opened on the top of the turntable 31 can contact the positioning frame 34, so that the positioning frame 34 moves and the rotor passes through the rotor bracket 63. At this time, it is only necessary to loosen the control rack 37. Under the action of the reset spring 38, the control rack 37 is reset, and 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, thereby controlling the positioning frame 34 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.

[0027] At this time, the hydraulic equipment 2 is started to assemble one set of stators and rotors. The hydraulic equipment 2 contacts the rotor, pushing the rotor and the rotor bracket 63 downward. When the rotor contacts the stator and the assembly is completed, the contact rod 46 contacts the triangular block 41 at the bottom of the control rack 37, pushing the control rack 37 to move to the side close to the main shaft 62, and the sliding rod 44 is inserted into the locking hole 47. At the same time, the L-shaped locking rod 51 is locked into the slot 54 on the inner side of the locking hole 47, thereby limiting the control rack 37.

[0028] At this time, since the control rack 37 moves toward 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, thereby completing the assembly of the rotor.

[0029] After assembly is completed, the hydraulic equipment 2 is controlled to move upward and reset. At this time, the rotor bracket 63 is no longer resisted downward. Under the action of the tension spring 11, the rotor bracket 63 moves upward with the control rack 37, and the control rack 37 moves upward with the slide bar 44. 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 90° clockwise. 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 90° clockwise together, thereby causing the other set of unassembled stators and rotors to rotate to the bottom of the hydraulic equipment 2.

[0030] When the slide bar 44 follows the control rack 37 to move upward for a certain distance, the connecting plate 55 is resisted by the fixed plate 56, and the connecting plate 55 disguisedly moves the connecting rod 53 and the L-shaped clamping rod 51 downward, and the L-shaped clamping rod 51 withdraws from the clamping groove 54 on the inner side of the clamping hole 47, thereby releasing the limit on the control rack 37. Under the action of the reset spring 38, the control rack 37 moves to the side away from the main shaft 62, and the slide bar 44 withdraws from the clamping hole 47, so that the slide bar 44 moves downward and resets 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, thereby failing to drive the main shaft 62 to rotate.

[0031] At this time, it is only necessary to continue placing the unassembled stator and rotor on the stator bracket 64 and the rotor bracket 63 to continuously carry out the assembly work, thereby effectively improving the overall work efficiency.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
