Description

Technical Field

[0001] The invention relates to the technical field of DC permanent magnet motor maintenance, in particular to a DC permanent magnet motor disassembly and assembly device. Background Art

[0002] Permanent magnet DC motor is a DC motor that uses permanent magnets to establish a magnetic field. It can be divided into permanent magnet brushless DC motor and permanent magnet brushed DC motor according to whether it has brushes or not. It is widely used in various portable electronic devices or appliances.

[0003] When repairing permanent magnet DC motors, it is often difficult or even impossible to disassemble them because of the permanent magnet strong magnetic blocks installed inside the motors. During installation, there is a serious safety hazard of squeezing fingers due to the strong magnetic attraction of metal. In addition, it is difficult to ensure that the air gap between the rotor and the stator is in a uniform state during installation, resulting in poor dynamic balance of the rotor after the motor is assembled, which seriously affects the stability of the motor rotation. Therefore, after this type of motor is damaged, it is often impossible to repair it and can only be replaced with a new DC permanent magnet motor. The procurement cost is huge and the procurement cycle is long. Summary of the invention

[0004] The present invention provides a DC permanent magnet motor disassembly and assembly device, which is used to solve the problem in the above technology that after the motor is damaged, it is often impossible to repair it and can only be replaced by purchasing a new DC permanent magnet motor.

[0005] The present invention provides a DC permanent magnet motor disassembly and assembly device, comprising:

[0006] A base, a fixed bearing assembly is mounted on the top surface of the base, and the fixed bearing assembly includes a vertical plate;

[0007] A moving component is arranged on one side of the fixed bearing component, and a card seat is slidably mounted on the moving component;

[0008] The sliding guide assembly is arranged at the rear side of the moving assembly, and the sliding guide assembly is matched with the card seat.

[0009] Preferably, a bearing tray 1 is slidably provided on one side surface of the vertical plate, a motor is placed on the top surface of the bearing tray 1, and an axle hole seat is provided in the middle of the end surface of the motor.

[0010] Preferably, a chuck is installed on the side of the chuck seat, and three clamping jaws are installed on the end surface of the chuck, which move toward the center at the same time, and the inner wall surfaces of the three clamping jaws are in tight contact with the outer surface of the shaft hole seat;

[0011] The end face center of the chuck is consistent with the center of the motor;

[0012] The end face center of the chuck is consistent with the center of the motor. At this time, the center of the chuck is in line with the center of the rear end cover of the motor, which makes it easier for the clamping claws to clamp the shaft hole seat.

[0013] Preferably, a second carrying pallet used in conjunction with the first carrying pallet is provided below the chuck;

[0014] The first bearing support plate and the second bearing support plate are arranged flush and in line, and the upper surfaces of the first bearing support plate and the second bearing support plate are both provided with a V-shaped inclined surface in contact with the outer surface of the motor;

[0015] The first load-bearing pallet and the second load-bearing pallet are arranged flush and in line, so that when the second load-bearing pallet squeezes and pushes the first load-bearing pallet, the stator housing and the rear end cover in the motor housing can enter into the second load-bearing pallet. The upper surfaces of the first load-bearing pallet and the second load-bearing pallet are both provided with a V-shaped inclined surface in contact with the outer surface of the motor, and are placed on the motor housing through the V-shaped inclined surface.

[0016] Preferably, a central bevel gear driven by a forward and reverse motor is installed in the middle of the inner cavity of the chuck, and three driven bevel gears are meshed on the end face of the central bevel gear, the three driven bevel gears are arranged in a ring, and each driven bevel gear is rotatably arranged with the inner wall surface of the chuck, and a screw is fixedly connected to the middle of the end face of each driven bevel gear;

[0017] The end surface of the chuck is provided with three sliding grooves, the screw rod and the inner wall surface of the sliding groove are rotatably arranged, and the outer surface of the screw rod is threadedly sleeved with a sliding seat, and the sliding seat is fixed to the surface of the corresponding clamping jaw;

[0018] Before clamping the shaft hole seat of the rear end cover of the motor, the clamping jaws connected to the three slides are away from each other and are located outside the shaft hole seat, and are installed in a ring shape on the end face of the chuck, with the three clamping jaws having the same center. When the end faces of the clamping jaws contact the rear end cover, the center bevel gear drives the three driven bevel gears to rotate together, and the three driven bevel gears simultaneously drive the screw to rotate in the corresponding sliding groove. Due to the threaded connection between the screw and the slide, the slide and the clamping jaws connected thereto move toward the center together. At this time, the three clamping jaws simultaneously tighten the outer surface of the shaft hole seat, thereby connecting the stator housing and the rear end cover together. When the front end cover and the stator housing are released from the installation connection, the three clamping jaws on the chuck are driven by the return of the clamping seat to separate the stator housing from the front end cover.

[0019] Preferably, a mounting hole for the motor shaft to enter is provided on the middle surface of the vertical plate, and a plurality of bolt holes aligned with the holes of the motor end cover are evenly provided on the outer surface of the mounting hole;

[0020] The end of the motor connected to the shaft (i.e. the front cover) is fitted with the surface of the vertical plate, and the shaft passes through the inside of the mounting hole. The motor is supported by a supporting plate. The position of the motor is rotated and adjusted so that the hole groove on the front cover is aligned with the bolt hole, and then the bolt is screwed in to fix the motor on the vertical plate.

[0021] Preferably, a through groove is provided on the surface of the vertical plate below the mounting hole, one end of the first supporting plate slides through the inside of the through groove, and a blocking plate is fixedly connected to the end of the first supporting plate;

[0022] Two fixing rods are fixed on the outer surface of the vertical plate, and fixing plates are fixed at the ends of the fixing rods, and the fixing rods and the blocking plates are slidably arranged, and a spring is installed between the blocking plate and the fixing plate. Initially, the spring is in a free state. When the bearing pallet two approaches the bearing pallet one, the end of the bearing pallet one is squeezed, so that the bearing pallet one slides in the through groove, and the blocking plate moves synchronously and slides within a limited position in the fixing rod. The spring is squeezed by the joint action of the blocking plate and the fixing plate. At this time, the spring is in an elastically compressed state, and the pushing end of the bearing pallet one reaches the front end cover of the motor. When the bearing pallet two is compressed and returned to its position, the bearing pallet one returns to its initial position under the elastic reset of the spring, which is convenient for the installation of the motor and the dismantling and maintenance of the next motor.

[0023] Preferably, two fixing rods are fixedly provided on the outer surface of the vertical plate, fixing plates are fixed to the ends of the fixing rods, and the fixing rods and the blocking plates are slidably arranged, and a spring is installed between the blocking plate and the fixing plate.

[0024] Preferably, the sliding guide assembly comprises a guide rail fixed on the upper surface of the base, a slider is slidably provided outside the guide rail, and the top surface of the slider is fixed to the lower surface of the holder by bolts.

[0026] The rotation of the screw is manually controlled by the rocker, and the screw is manually provided with rotational power. The screw rotates in the two screw seats, and then the nut seat and the screw thread rotate, converting the rotational motion into linear motion, driving the cassette to move. Due to the limit guide of the slider at the bottom of the cassette on the guide rail, the cassette and its side supporting plate 2 and the chuck are driven to move along the guide rail.

[0027] Compared with the prior art, the advantages of the present invention are:

[0028] 1. First, place the motor housing steadily on the bearing tray 1, and then use bolts to fix the front end cover of the motor to the vertical plate, and then by toggling the moving component, the holder is driven by the moving component and slides in a limited position along the direction of the sliding guide component to ensure the stable movement of the holder. At this time, the holder drives the chuck and the bearing tray 2 to approach the rear end cover of the motor and the bearing tray 1 respectively, and the bearing tray 2 squeezes and pushes the bearing tray 1, so that the bearing tray 1 slides in the vertical plate, and the bearing tray 2 does not move to the position of the front end cover of the motor, and the positioning housing and its rear end cover are supported by the bearing tray 2, and the three clamps are close to the outside of the motor shaft hole seat until the end face of the clamp contacts the surface of the rear end cover to stop the movement of the holder, and then the three clamps move toward the center at the same time, automatically adjusting the opening of the clamps so that the three clamps are in tight contact with the shaft hole surface at the same time to ensure the shaft hole The seat and the clamping claw cannot be easily separated, and then the connection restriction between the front end cover and the stator housing on the motor is released. The clamping seat and the second bearing support plate are driven to reset in the reverse direction by the moving component, and the chuck and its removed stator housing and its rear end cover are driven to retreat and reset, so that the stator housing and the front end cover of the DC permanent magnet motor can be separated. The stator housing and the rear end cover are supported by the setting of the second bearing support plate to provide auxiliary support to avoid the possibility of falling during removal. After the motor is repaired, the end cover, the stator housing and the rotor are assembled through the device to ensure the relative position of the end cover and the stator housing, and to ensure that the air gap between the stator and the rotor remains unchanged before disassembly, thereby ensuring the reliability of the motor after assembly, overcoming the difficult disassembly and assembly caused by the strong suction of the stator strong magnetic block and the safety hazards in the disassembly and assembly process. Through disassembly and assembly repair, there is no need to purchase new equipment, saving costs;

[0029] 2. The central bevel gear drives the three driven bevel gears to rotate together. The three driven bevel gears drive the screw to rotate in the corresponding sliding groove at the same time. Due to the threaded connection between the screw and the slide, the slide and its connected jaws move toward the center together (that is, the three jaws move toward the center at the same time), ensuring the consistency of movement, improving the tightness of the connection between the jaws and the shaft hole seat, and automatically tightening without manual adjustment.

[0123] like Figure 1-Figure 4 As shown, the present invention provides a DC permanent magnet motor disassembly and assembly device, comprising:

[0124] A base 1, a fixed bearing assembly is installed on the top surface of the base 1, and the fixed bearing assembly includes a vertical plate 2;

[0125] A moving component is arranged on one side of the fixed bearing component, and a card seat 9 is slidably mounted on the moving component;

[0126] A sliding guide assembly is arranged at the rear side of the moving assembly, and the sliding guide assembly cooperates with the card seat 9;

[0127] The sliding guide assembly is arranged at the rear side of the moving assembly, and the sliding guide assembly cooperates with the card seat 9, and the sliding guide assembly includes a guide rail 13 fixed on the upper surface of the base 1, and a slider 10 is slidably arranged outside the guide rail 13, and the top surface of the slider 10 is fixed to the lower surface of the card seat 9 by bolts;

[0128] The moving component is arranged on one side of the fixed bearing component, and a card seat 9 is slidably mounted on the moving component. The moving component includes two screw seats 5, a screw 6 is rotatably mounted between the two screw seats 5, and a nut seat 7 is provided on the external thread sleeve of the screw 6. The upper surface of the nut seat 7 is fixed to the lower surface of the card seat 9, and a rocker 8 for driving the screw 6 to rotate is installed on the surface of one of the screw seats 5;

[0129] The rotation of the lead screw 6 is manually controlled by the rocker 8, and the rotational power is manually provided to the lead screw 6. The lead screw 6 rotates in the two lead screw seats 5, and then the nut seat 7 and the lead screw 6 threadedly rotate, converting the rotational motion into linear motion, driving the base 9 to move. Due to the limited guidance of the slider 10 at the bottom of the base 9 on the guide rail 13, the base 9 and its side supporting plate 2 4 and the chuck 11 are driven to move along the guide rail 13.

[0130] When the present invention is in use, the motor housing is first placed stably on the bearing support plate 3, and then the front end cover of the motor is fixed to the vertical plate 2 by bolts, and then the moving assembly is toggled, and the holder 9 is driven by the moving assembly and slides in a limited position along the direction of the sliding guide assembly to ensure the stable movement of the holder 9. At this time, the holder 9 drives the chuck 11 and the bearing support plate 2 4 to approach the rear end cover of the motor and the bearing support plate 3 respectively, and the bearing support plate 2 4 squeezes and pushes the bearing support plate 3, so that the bearing support plate 3 slides in the vertical plate 2, wherein the bearing support plate 2 4 does not move to the position of the front end cover of the motor, and the positioning housing and its rear end cover are supported by the bearing support plate 2 4, and the three clamping claws 12 are close to the outside of the motor shaft hole seat 21 until the end face of the clamping claw 12 contacts the surface of the rear end cover to stop the movement of the holder 9, and then the three clamping claws 12 move toward the center at the same time, and the opening of the clamping claw 12 is automatically adjusted so that the three clamping claws 12 are simultaneously with the shaft The hole surface is in tight contact, ensuring that the shaft hole seat 21 and the clamping claw 12 cannot be easily separated, and then the connection restriction between the front end cover and the stator housing on the motor is released, and the clamping seat 9 and the bearing support plate 24 are driven to reset in the reverse direction by the moving component, and the chuck 11 and its removed stator housing and its rear end cover are driven to retreat and reset, so that the stator housing and the front end cover of the DC permanent magnet motor can be separated. Through the setting of the bearing support plate 24, the stator housing and the rear end cover are supported to provide auxiliary support to avoid the possibility of falling during removal. After the motor is repaired, the end cover, stator housing and rotor are assembled through the device to ensure the relative position of the end cover and the stator housing, and to ensure that the air gap between the stator and the rotor remains unchanged before disassembly, thereby ensuring the reliability of the motor after assembly, overcoming the problems of difficult disassembly and assembly caused by the strong suction of the stator strong magnetic block and the potential safety hazards in the disassembly and assembly process, and through disassembly and assembly repair, there is no need to purchase new equipment, saving costs;

[0131] The central bevel gear 22 drives the three driven bevel gears 23 to rotate together, and the three driven bevel gears 23 drive the screw rod 25 to rotate in the corresponding sliding groove 24 at the same time. Due to the threaded connection between the screw rod 25 and the slide seat 26, the slide seat 26 and the clamping jaws 12 connected thereto move together toward the center, that is, the three clamping jaws 12 move toward the center at the same time, thereby ensuring the consistency of movement, improving the tightness of the connection between the clamping jaw 12 and the shaft hole seat 21, and automatically tightening without manual adjustment.

[0132] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention.
