Description

Technical Field

[0001] This invention belongs to the field of motor disassembly technology, and particularly relates to a disassembly assembly for a brushless DC torque motor shaft. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by a current-carrying coil (stator winding) that acts on the rotor (such as a squirrel-cage closed aluminum frame) to create a magnetoelectric torque. Electric motors are classified into DC motors and AC motors based on the power source they use. Most motors in power systems are AC motors, which can be synchronous or asynchronous (the stator magnetic field speed and rotor rotation speed are not synchronized). An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] A search revealed that application number CN202021307960.X discloses a disassembly assembly for a water pump. The water pump has a mounting plate at its bottom with multiple bolt holes. The water pump housing and end cover are interference-fitted. The disassembly assembly includes a base plate, a movable plate, a linear drive mechanism, and a fixed base. The base plate is horizontally positioned, and the movable plate is vertically positioned and slidably connected to the base plate along its length. The movable plate has an opening for accommodating the water pump housing and end cover, extending vertically downwards. Top rod assemblies are installed on the left and right sides of the opening on the movable plate. Compared with manual prying, the wedge block makes surface contact with the water pump end cover, and both sides of the end cover can be stressed simultaneously, resulting in more even stress distribution and reducing the risk of damage to the water pump end cover and housing. Furthermore, it eliminates the need for laborious manual prying, making the disassembly process more effortless.

[0004] The problem with the above technical solution is that when the motor is used for a long time, the motor shaft is prone to wear, so the staff needs to disassemble and maintain the motor regularly. It is not convenient to fix the motor during the disassembly and maintenance process, which increases the difficulty of disassembling the motor and reduces the maintenance efficiency.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The starting motor shaft clamping and fixing assembly of this invention can fix and clamp the motor output shaft, and then drive the housing fixing assemblies on both sides of the load-bearing plate to move inward to the load-bearing plate, achieving initial limiting of the outer side of the motor. After initial limiting, the starting housing fixing assembly can initially fix the motor housing, which facilitates the disassembly of the motor housing by the workers, thus improving the disassembly efficiency of the motor. After disassembly, the starting shaft conveying assembly can convey the motor shaft, thereby better disassembling the shaft and speeding up the work efficiency. The dual-shaft motor drives the positive and negative lead screws on both sides to rotate, and the positive and negative lead screws on both sides are connected by screws. The meshing connection has a slider, which can drive the support rod to support the lower fixed rod. After support, the first limiting plate limits the connecting sheet metal to move towards the center along the lower and upper fixed rods. The lower and upper fixed rods are vertically installed together through the connecting sheet metal, which not only drives the lower and upper fixed rods to rise and fall, but also, through the second limiting plate, drives the two side clamps to move towards the center along the limiting sleeve to clamp and fix the motor shaft. Furthermore, since the connecting rod and connecting frame are installed between the second limiting plate, the two side housing fixing components can move with the second limiting plate, thus providing initial limitation for the motor on the load-bearing plate.

[0016] 2. The present invention starts the conveyor motor to drive the rotating shaft to rotate. Since each rotating shaft is installed through sprocket and chain drive, each rotating shaft can rotate in the same direction. When the rotating shaft rotates, it can drive the traveling gear to rotate. The traveling gear is connected to the toothed plate through the meshing of the toothed teeth, which can drive the clamp to move along the toothed plate. When it moves to the ends of both ends of the toothed plate, it can drive the roller on the mounting rod to embed into the upper and lower clamping blocks, thereby limiting and fixing the clamp, and effectively transporting the disassembled rotating shaft. Then, the single-axis motor drives the drive screw to rotate. The drive screw drives the lifting plate to move up and down in the mounting shell. At the same time, the extension rod on the lower surface of the lifting plate can drive the top rod to rotate around the central axis. Then, the second top plate at one end of the top rod and the first top plate on the connecting rod clamp and fix the motor shell. Attached Figure Description

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 9As shown in the figure, an embodiment of the present invention provides a brushless DC torque motor shaft disassembly assembly, including a support frame 1, a motor shaft clamping and fixing assembly 2, a shaft conveying assembly 4, and a housing fixing assembly 9. The shaft conveying assembly 4 includes a mounting box 401, which is fixedly connected to the middle of the outer surface of the clamp 5. A conveying motor 410 is fixedly connected to one side of the inner wall of the mounting box 401. The output shaft of the conveying motor 410 is fixedly connected to a shaft 411. The shaft 411 is also disposed on both sides inside the mounting box 401. The three shafts 411 are installed together through a sprocket 412 and a chain 413. The motor shaft clamping and fixing assembly 2 includes a slide groove 201, which is disposed on the support frame 1, the motor shaft clamping and fixing assembly 2, the motor shaft clamping and fixing assembly 2, and the housing fixing assembly 9. Below the inner wall of the support frame 1, a dual-axis motor 202 is fixedly connected to the middle of the inner wall of the slide groove 201. The output shafts at both ends of the dual-axis motor 202 are fixedly connected to positive and negative lead screws 203. The threads of the positive and negative lead screws 203 on both sides are opposite. The positive and negative lead screws 203 are connected to the slider 204 through the surface thread engagement. The housing fixing assembly 9 includes a central shaft 902, which is fixedly connected between the inner walls of the groove 8. A top rod 909 is movably installed on the central shaft 902. A limit groove 910 is provided in the middle of the top rod 909. An extension rod 908 is installed in the limit groove 910. A lifting plate 907 is fixedly connected to the upper end of the extension rod 908. The lifting plate 907 is installed inside the housing 904.

[0030] A disconnection is provided above the support frame 1. Two support frames 1 are arranged in parallel. Each support frame 1 is equipped with a motor shaft clamping and fixing assembly 2. A clamping plate 3 is installed on the motor shaft clamping and fixing assembly 2. A shaft conveying assembly 4 is installed on the upper end of one clamping plate 3. A clamp 5 is installed on the shaft conveying assembly 4. A connecting frame 7 and a connecting rod 6 are installed between the two motor shaft clamping and fixing assemblies 2. A housing fixing assembly 9 is installed between the connecting frame 7 and the connecting rod 6. A load-bearing plate 10 is also installed between the two motor shaft clamping and fixing assemblies 2. First, the motor to be disassembled is placed on the load-bearing plate. After the surface is 10, the motor shaft clamping and fixing assembly 2 can clamp and fix the motor output shaft. Then, it can drive the housing fixing assemblies 9 on both sides of the load-bearing plate 10 to move inward to the load-bearing plate 10, so as to initially limit the outer side of the motor. After the initial limit, the housing fixing assembly 9 can initially fix the motor housing. After fixing, it is convenient for the staff to disassemble the motor housing, thus improving the disassembly efficiency of the motor. After disassembly, the shaft conveying assembly 4 can convey the motor shaft, thereby better disassembling the shaft and speeding up the work efficiency.

[0031] Each rotating shaft 411 has a fixedly mounted traveling gear 414 at the same end. A gear plate 403 is connected below each traveling gear 414 via a meshing mechanism. The gear plate 403 is fixedly connected to the upper end of the clamping plate 3. A limit block 405 is fixedly connected to one side surface of the gear plate 403. A fitting block 404 is installed in conjunction with the limit block 405 and is fixedly connected to the lower surface of the mounting box 401. Fixed sheet metal 402s are fixedly connected to both sides of the mounting box 401. A mounting rod 406 is rotatably mounted on one side of the inner wall of the fixed sheet metal 402s on both sides. Rollers 407 are rotatably mounted above and below one end of each mounting rod 406. Upper locking blocks 408 are provided on both sides of the upper rollers 407 and are fixedly connected to one side of the inner wall of the fixed sheet metal 402. The lower roller 407 is fitted with a lower locking block 409, which is fixedly connected to both ends of the side surface of the toothed plate 403. When the conveyor motor 410 is started, it drives the rotating shaft 411 to rotate. Since each rotating shaft 411 is installed through a sprocket 412 and a chain 413, each rotating shaft 411 can rotate in the same direction. When the rotating shaft 411 rotates, it can drive the traveling gear 414 to rotate. The traveling gear 414 is connected to the toothed plate 403 through the meshing of the teeth, which can drive the clamp 5 to move along the toothed plate 403. When it moves to the ends of both ends of the toothed plate 403, it can drive the roller 407 on the mounting rod 406 to embed into the upper locking block 408 and the lower locking block 409, thereby limiting and fixing the clamp 5 and effectively transporting the disassembled rotating shaft.

[0032] The other end of the top rod 909 is fixedly connected to the second top plate 911. One end of the lifting plate 907 is threadedly connected to the drive screw 906. The lower end of the drive screw 906 is fixedly connected to the single-axis motor 905. The single-axis motor 905 is mounted on the lower surface of the mounting housing 904. The upper end of the mounting housing 904 is rotatably mounted on the connecting rod 6. The connecting rod 6 is also rotatably mounted on the sliding plate 901. The two ends of the sliding plate 901 are equipped with slide rails 11. The two slide rails 11 are fixedly connected to the inner surfaces of the two side support frames 1. Rotatably mounted on connecting rod 6, the front end of slide plate 901 is fixedly connected to top plate 903. Single-axis motor 905 drives drive screw 906 to rotate, and drive screw 906 drives lifting plate 907 to move up and down inside mounting housing 904. While moving, the extension rod 908 on the lower surface of lifting plate 907 can drive top rod 909 to rotate around central axis 902. Then, the motor housing is clamped and fixed by top plate 911 at one end of top rod 909 and top plate 903 on connecting rod 6.

[0033] Support rods 205 are rotatably mounted on the sliders 204 on both sides. Mounting seats 206 are rotatably mounted on the upper ends of the support rods 205 on both sides. Lower fixing rods 207 are fixedly connected to the upper surfaces of the mounting seats 206 on both sides. Upper fixing rods 208 are set above the lower fixing rods 207. Connecting sheet metal 209s are movably mounted at both ends of the lower fixing rods 207 and the upper fixing rods 208. A first limiting plate 210 is rotatably mounted between the connecting sheet metal 209s on both sides and the support frame 1. A second limiting plate 211 is rotatably mounted on the connecting sheet metal 209s on both sides. Clamping plates 3 are rotatably mounted on the second limiting plates 211 on both sides. Limiting sleeves 212 are installed on the outer side of the clamping plates 3. The limiting sleeves 212 are fixedly connected to the disconnection at the upper end of the support frame 1. The dual-axis motor 202 drives the positive and negative lead screws 203 on both sides to rotate. The positive and negative lead screws 203 on both sides are connected by screws The sliding block 204 is connected by a meshing mechanism. The sliding block 204 can drive the support rod 205 to support the lower fixed rod 207. After support, the connecting sheet metal 209 moves towards the center along the lower fixed rod 207 and the upper fixed rod 208 after being limited by the first limiting plate 210. The lower fixed rod 207 and the upper fixed rod 208 are vertically installed together through the connecting sheet metal 208. This achieves the simultaneous lifting and lowering of the lower fixed rod 207 and the upper fixed rod 208, and the limiting by the second limiting plate 211. This causes the clamping plates 3 on both sides to move towards the center along the limiting sleeve 212 to clamp and fix the motor shaft. Furthermore, since the connecting rod 6 and the connecting frame 7 are installed between the second limiting plate 211, the fixing components 9 on both sides of the housing can move with the second limiting plate 211, thus providing initial limitation for the motor on the load-bearing plate 10.

[0034] Working principle of the invention:

[0035] In use, starting the motor shaft clamping and fixing assembly 2 can clamp and fix the motor output shaft. This then drives the housing fixing assemblies 9 on both sides of the load-bearing plate 10 to move inwards towards the load-bearing plate 10, achieving initial limiting of the motor's outer side. After initial limiting, starting the housing fixing assembly 9 can initially fix the motor housing, facilitating disassembly and improving disassembly efficiency. After disassembly, starting the shaft conveying assembly 4 can convey the motor shaft, further improving disassembly and accelerating work efficiency. The dual-shaft motor 202 drives the positive and negative lead screws 2 on both sides. 03 Rotation, the positive and negative lead screws 203 on both sides are connected to the slider 204 through thread engagement. The slider 204 can drive the support rod 205 to support the lower fixed rod 207. After support, the first limit plate 210 drives the connecting sheet metal 209 to move towards the center along the lower fixed rod 207 and the upper fixed rod 208. At the same time, the second limit plate 211 supports the two clamping plates 3 to move towards the center along the limit sleeve 212 to clamp and fix the motor shaft. Since the connecting rod 6 and the connecting frame 7 are installed between the second limit plate 211, the two housing fixing components 9 can be driven to move with the second limit plate 211.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can exercise their rights without departing from the scope of the present invention.
