[0002] In an extended-range vehicle, the engine has a higher power, larger size and weight than the generator motor of a traditional fuel vehicle. During the maintenance of the generator motor, because the magnetic steel of the rotor has a strong magnetic field, the stator and rotor will be attracted to each other during the disassembly process. The adsorption of the stator and rotor may destroy the structural characteristics of the stator and rotor, which will cause economic losses. In addition, the adsorption force of the stator and rotor is large, far exceeding the strength limit of ordinary people. Professional tools are required to disassemble the stator and rotor. There is no tool specifically used to remove the stator and rotor of the motor in the prior art. Utility Model Content

[0003] Based on the above description, the utility model provides a motor stator and rotor removal tool for an engine assembly on an extended-range vehicle, aiming to solve the problem of difficulty in disassembling the stator and rotor during maintenance of the generator motor in the extended-range vehicle.

[0029] like Figure 1 As shown, an embodiment of the present application provides a motor stator and rotor removal tool for an engine assembly on an extended-range vehicle, which includes a fixed bracket 10, a screw rod 20, a transmission nut 30 and a movable bracket 40.

[0030] Among them, the fixing bracket 10 includes a fixing plate 11 and a plurality of guide pillars 12 arranged at the lower end of the fixing plate 11, and the lower end of the guide pillar 12 is used to be fixed to the engine 200 assembly. Specifically, the lower end of the guide pillar 12 has a fastening structure connected to the engine 200. In this embodiment, the lower end of the guide pillar 12 is provided with a thread, which is penetrated and arranged on the outer shell of the engine 200 assembly. The fastening structure is a nut that fixes the engine 200 and the guide pillar 12 relatively.

[0031] Among them, the screw rod 20 can be rotatably installed on the fixed plate 10; specifically, a mounting hole 10a is formed in the middle of the fixed plate 11, and the part of the screw rod 20 close to the upper end can be rotatably connected to the mounting hole 10a through a screw rod rotating bearing 111, thereby realizing the rotational connection of the screw rod 20 relative to the fixed plate 10.

[0032] Preferably, the screw rod 20 is arranged in the middle of the fixed plate 10, and the number of the guide pillars 12 is three, and the three guide pillars 12 are evenly distributed along the circumference of the screw rod 20 to ensure accurate guidance of the movable bracket 40 during movement and prevent the stator or rotor from being offset when being taken out, resulting in impact damage.

[0033] The movable bracket 40 is slidably mounted on the guide pillar 12 , the transmission nut 30 is fixedly mounted on the movable bracket 40 and threadedly connected to the screw rod 20 , and the movable bracket 40 is used to be connected to the stator or rotor of the motor.

[0034] In order to ensure the smooth movement of the movable bracket 40 relative to the guide pillar, the movable bracket 40 is fixedly provided with a lubricating part 41 corresponding to the guide pillar 12, and the lubricating part 41 is slidably sleeved on the outer side of the corresponding guide pillar 12. Preferably, the lubricating part 41 is a linear bearing, an oil-free bushing or other guide lubrication structure.

[0035] In the present application, the screw rod 20 is driven by the rotation of the rotating handle 50. Specifically, the upper end of the screw rod 20 passes through the fixed plate 11 and is fixedly connected to the rotating handle 50. In order to facilitate the installation of the rotating handle, a square positioning pin 21 is formed at the upper end of the screw rod 20, and a positioning hole that cooperates with the square positioning pin 21 is formed at the lower end of the rotating handle 50. When in use, the rotating handle 50 is inserted, and it can be directly removed when not in use. Alternatively, a key can be formed at the upper end of the screw rod 20, and the positioning hole at the lower end of the rotating handle 50 forms a key connection with the key.

[0036] When using the embodiment of the present application, first, the first step is as follows: Figure 2As shown, the three guide pillars 12 with the movable bracket 40 are installed on the housing of the engine 200 assembly, and then the screw rod 20 is installed on the drive nut on the movable bracket 40. The movable bracket 40 and the stator 201 of the motor are locked by bolts. Then, in the second step, as shown in FIG. Figure 3 Combination Figure 1 As shown, the fixing plate 11 is installed on the upper end of the guide pillar 12, wherein the screw rod 20 is matched with the screw rod rotating bearing 111. At this time, the square positioning pin 21 at the upper end of the screw rod 20 extends to the upper end of the fixing plate 11. Finally, in the third step, as shown in FIG. Figure 4 Combination Figure 3 As shown, the rotating handle 50 is correspondingly mounted on the square positioning pin 21. At this time, by rotating the handle 51 on the rotating handle 50, the screw rod 20 can be rotated, and the transmission nut 30 drives the movable bracket 40 to move, thereby pulling the stator 201 of the motor out of the motor. During the pulling-out process, the guide pillar 12 is used to guide the stator or the rotating stator 201, thereby ensuring that the stator will not deviate when being pulled out, thereby effectively preventing damage caused by collision with each other.

[0037] The motor stator and rotor removal tooling provided in the present application is a purely mechanical mechanism. All connections are mechanically connected, can be quickly locked, and have a low failure rate in long-term use. The rotation of the screw rod is manually adjusted, and no power or air source is required. The design is very environmentally friendly and energy-saving. The motor stator and rotor removal tooling can be used to completely remove the stator or rotor from the engine 200, which is of great significance for the re-online manufacturing of the engine 200 or the debugging of new products, and can effectively reduce the scrap rate during maintenance.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
