Description

Technical Field

[0001] This utility model relates to the field of motor structure technology, specifically to a motor rotor mounting device. Background Technology

[0002] With the rapid development of science and technology, motors are needed in various fields. The development of motors has also promoted the continuous improvement of social productivity. A motor consists of two parts: a rotor and a stator. The motor rotor is divided into a motor rotor and a generator rotor. The rotor plays a vital role in the motor and needs to be properly installed and fixed.

[0003] Most existing motor shafts and rotors are assembled using an interference fit. The entire assembly process requires operators to use tools directly, which is time-consuming and labor-intensive. Furthermore, when the assembled motor is subjected to force, the rotor is prone to offset and self-rotation on the motor shaft, resulting in poor assembly stability. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems by providing a motor rotor mounting device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A motor rotor mounting device includes a connecting platform arranged opposite to each other and a pneumatic four-jaw clamp disposed on the connecting platform. Limiting devices for fixing the motor shaft are slidably connected to the two connecting platforms.

[0007] The limiting device includes a slider that slides to connect the connecting platform. A fixed column is installed on the slider. A movable screw is internally threaded to the fixed column. A limiting block is installed on one side of the movable screw. Multiple sets of movable arms are hinged to the side of the fixed column near the pneumatic four-jaw chuck. Movable connecting arms are installed between the limiting block and the multiple movable arms.

[0008] The connecting platform is equipped with a drive device that pushes the limiting device close to the pneumatic four-jaw clamp.

[0009] Preferably, the pneumatic four-jaw clamp and the fixing column are coaxially arranged.

[0010] Preferably, the two ends of the connecting arm are respectively hinged to a movable arm and a limiting block.

[0011] Preferably, the driving device includes a toothed plate connected between two connecting platforms and a rotating shaft connected to a slider via a bearing.

A rotating gear is rotatably connected to the outside of the rotating shaft and meshes with the toothed plate.

[0012] Preferably, connecting plates are arranged opposite each other on one side of the connecting platform, and stepping screws are threadedly connected to the two connecting plates, with one end of the stepping screws abutting against the slider.

[0013] Preferably, a connecting block is installed at the other end of the stepper screw, and a through hole is formed on the connecting block, in which an extension arm is movably installed.

[0014] Preferably, the pneumatic four-jaw clamp is mounted on the connecting platform via a bracket.

[0015] With the above structure, this utility model has the following advantages:

[0016] This invention uses a pneumatic four-jaw clamp and a limiting device to fix the motor rotor and the main shaft, and uses a drive device to install the main shaft inside the motor rotor.

[0025] The present invention will now be described in further detail in conjunction with the full text.

[0026] Combined with appendix Figures 1-3 A motor rotor mounting device includes a connecting platform 1 and a pneumatic four-jaw clamp 5 mounted on the connecting platform 1. A limiting device 2 for fixing the motor shaft is slidably connected to the two connecting platforms 1. The limiting device 2 includes a slider 201 slidably connected to the connecting platform 1, a fixing post 202 mounted on the slider 201, a movable screw 203 internally threaded onto the fixing post 202, a limiting block 204 mounted on one side of the movable screw 203, and multiple sets of movable arms 205 hinged to the side of the fixing post 202 near the pneumatic four-jaw clamp 5. Movable connecting arms 206 are mounted between the limiting block 204 and the multiple movable arms 205. The pneumatic four-jaw clamp 5 and the fixing post 202 are coaxially arranged to ensure that the motor shaft and rotor maintain the same axis, preventing deviation of the motor shaft during installation. One end of the connecting arm 206 is hinged to the limiting block 204, and the other end is hinged to the middle of the movable arm 205. When the movable screw 203 rotates and moves within the fixed column 202, it drives the limit block 204 to move, which in turn drives multiple movable arms 205 to clamp the motor shaft through the connecting arm 206, ensuring that the motor shaft and the fixed column 202 are on the same axis.

[0027] In specific implementation of this utility model, such as Figures 1-3As shown. A drive device 3 is installed on the connecting platform 1 to push the limiting device 2 closer to the pneumatic four-jaw clamp 5. The drive device 3 includes a toothed plate 301 connected between the two connecting platforms 1 and a rotating shaft 302 connected to the slider 201 via a bearing. The lower end of the slider 201 has a groove 303 and the rotating shaft 302 extends into the groove 303. A rotating gear 304 is rotatably connected to the outside of the rotating shaft 302 and meshes with the toothed plate 301. The rotating shaft 302 rotates through the bearing, driving the rotating gear 304 to rotate outside the toothed plate 301. The toothed plate 301 is fixedly connected between the connecting platforms 1, so the rotating gear 304 drives the slider 201 to move on the connecting platform 1 in the opposite direction.

[0028] Specifically, connecting plates 305 are arranged opposite each other on one side of the connecting platform 1. Stepping screws 306 are threadedly connected to the two connecting plates 305, and one end of the stepping screws 306 can abut against the slider 201. A connecting block 307 is installed on the other end of the stepping screws 306. A through hole 308 is opened on the connecting block 307, and an extension arm 309 is movably installed in the through hole 308. The stepping screws 306 rotate and move threadedly on the connecting plates 305, which can abut against the slider 201 and move. They can also move through the through hole 308 via the extension arm 309 and then rotate, which saves effort. The arrangement of the two connecting plates 305 can ensure the consistency of the movement direction of the stepping screws 306.

[0029] Specifically, a rapidly rotating handle is installed on one side of both the rotating shaft 302 and the moving screw 203.

[0030] In specific implementation of this utility model, such as Figure 1 As shown, the pneumatic four-jaw clamp 5 is mounted on the connecting platform 1 via the bracket 4. The pneumatic four-jaw clamp 5 is connected to the connecting platform 1 via the bracket 4 and bolt assembly. The pneumatic four-jaw clamp 5 is existing technology. The pneumatic four-jaw clamp 5 can clamp the rotor and can use a pneumatic finger cylinder MHS3 or an equivalent type of clamp, which will not be described in detail here.

[0031] The working principle of this utility model:

[0032] First, fix the connecting platform 1 in a suitable position. The pneumatic four-jaw clamp 5 clamps the rotor. When the moving screw 203 rotates and moves within the fixed column 202, it drives the limit block 204 to move. Through the connecting arm 206, it drives multiple movable arms 205 to clamp the motor shaft. The rotating shaft 302 rotates through the bearing, driving the rotating gear 304 to rotate on the outside of the toothed plate 301. The toothed plate 301 is fixedly connected between the connecting platforms 1. Therefore, the rotating gear 304 drives the slider 201 to move on the connecting platform 1 and approach the rotor. When the reverse force is too great and installation is impossible, the extension arm 309 can move through the through hole 308 and then rotate. The stepping screw 306 rotates and moves on the connecting plate 305, which can resist the movement of the slider 201, thus saving effort and completing the installation of the motor shaft.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
