[0001] This utility model relates to the field of motor assembly technology, and in particular to a convenient tool for disassembling and assembling electric motors. Background Technology

[0002] The main components of a permanent magnet motor include the housing, flange, stator, and rotor. The stator is mainly composed of the stator core, coils, and frame. The rotor is mainly composed of the rotor core and permanent magnets. The permanent magnets are assembled in the rotor core slots. The stator is fixedly installed inside the housing, and the rotor is located inside the stator. There is an air gap between the stator and the rotor, which causes the rotor to rotate under the action of magnetic force.

[0003] A search of existing Chinese patent technology reveals a "Permanent Magnet Motor Disassembly and Assembly Tool" with publication number "CN222802713U". This device reliably secures the rotor in the air. The rotor lifting mechanism both lifts and straightens the rotor, ensuring coaxiality and preventing rotor misalignment that could lead to wear or collision damage. During use, bushings are fitted at both ends of the stator on the central rotor. Disassembly requires pulling the bushings off. However, this device struggles to effectively pull the bushings during motor disassembly and assembly, resulting in poor disassembly and assembly efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a convenient motor disassembly and assembly tool to address the problem that it is difficult to achieve a good pulling effect on the bushing, resulting in poor motor disassembly and assembly and affecting the efficiency of motor disassembly and assembly work.

[0005] A convenient electric motor disassembly and assembly tool is provided, comprising: a base frame, the lower end of which has two guide grooves, and a connecting frame fixedly connected to the upper end of the base frame; a pull-out disassembly and assembly mechanism, which is mounted on the surface of the connecting frame and extends into the interior of the guide grooves; wherein the pull-out disassembly and assembly mechanism includes a biting component mounted on the inner side of the connecting frame, and adjusting components are provided on both sides of the biting component. The adjusting components are mounted on the side of the connecting frame, and positioning components are connected to the surfaces of the two biting components. The lower end of the positioning component extends into the interior of the guide groove.

[0006] In one embodiment, the positioning component includes two circular sleeves rotatably connected to the surfaces of adjacent control components. A vertical plate is fixedly connected to the lower end of each circular sleeve, and a sliding seat is fixedly connected to the lower end of each vertical plate. The sliding seat is slidably connected to the inner wall of the guide groove.

[0007] In one embodiment, the control assembly includes two side frames fixedly connected to the side of the connecting frame. The inner walls of the two side frames are fixedly connected with threaded sleeves, and the inner walls of the threaded sleeves are threadedly connected with threaded rods. One end of the threaded rods is fixedly connected with a handle.

[0008] In one embodiment, the engagement assembly includes an inner frame fixedly connected to the inside of the connecting frame, with sliding grooves on both sides of the inner frame and engagement buckles fixedly connected to the inner bottom wall of the inner frame.

[0009] In one embodiment, a plurality of side grooves are provided on one side of the vertical plate, and the plurality of side grooves are evenly distributed longitudinally along the surface of the vertical plate.

[0010] In one embodiment, a support plate is inserted into the inside of the side groove, and two waist holes are formed at the upper end of the support plate.

[0011] In one embodiment, a connector is fixedly connected to the other end of the threaded rod, and a round rod is fixedly connected to the surface of the connector away from the threaded rod.

[0012] In one embodiment, a crossbeam is slidably connected to the inner wall of the chute, the end of the crossbeam passing through the chute and extending to the outside of the inner frame. Beneficial effects

[0013] 1. The above-mentioned convenient motor disassembly and assembly tool, through the set pull disassembly and assembly mechanism, can provide good support for the motor during use. The lower end of the crossbeam engages with the snap fastener to properly position the bushing. The drive engagement component can move the motor, which will result in a good pull effect on the bushing during the movement of the motor, thus ensuring the efficiency of motor disassembly and assembly.

[0014] 2. During the pulling operation, the knob handle drives the threaded rod to rotate, which in turn moves the threaded rod horizontally in conjunction with the threaded sleeve. The connecting head then moves the round rod, thereby adjusting the motor position and performing the pulling and disassembly operation. This optimizes the motor disassembly and assembly effect and ensures the efficiency of the motor disassembly and assembly work. Attached Figure Description

[0024] The following is combined Figures 1-5 This invention describes a convenient tool for disassembling and assembling electric motors.

[0025] In one embodiment, a portable electric motor disassembly and assembly tool includes: a base frame 1, with two guide grooves 11 at the lower end of the base frame 1, and a connecting frame 2 fixedly connected to the upper end of the base frame 1; a pull-out disassembly and assembly mechanism 3, which is mounted on the surface of the connecting frame 2 and extends into the interior of the guide grooves 11; wherein, the pull-out disassembly and assembly mechanism 3 includes a biting component 33 mounted on the inner side of the connecting frame 2, and an adjustment component 31 is provided on both sides of the biting component 33. The adjustment component 31 is mounted on the side of the connecting frame 2, and a positioning component 32 is connected to the surface of the two biting components 33. The lower end of the positioning component 32 extends into the interior of the guide groove 11.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the positioning component 32 includes two circular sleeves 321 that are rotatably connected to the surfaces of adjacent control components 31. A vertical plate 322 is fixedly connected to the lower end of the circular sleeve 321. A sliding seat 323 is fixedly connected to the lower end of the vertical plate 322. The sliding seat 323 is slidably connected to the inner wall of the guide groove 11. A plurality of side grooves 324 are provided on one side of the vertical plate 322. The plurality of side grooves 324 are evenly distributed longitudinally along the surface of the vertical plate 322. A support plate 325 is inserted into the inside of the side groove 324. Two waist holes 326 are provided at the upper end of the support plate 325.

[0027] In this embodiment, the device supports the motor by means of a support plate 325, the two ends of which extend to the outside of the side grooves 324 and are then positioned by bolts, thus preventing the support plate 325 from easily shaking when supporting the motor. The waist hole 326 can be used to connect and position the deposit, and the support position can be adjusted according to different motor models by means of the cooperation between the multiple side grooves 324 and the support plate 325. Under the guidance of the sliding seat 323, it works with the guide groove 11 to form a good guiding effect.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the control assembly 31 includes two side frames 311 fixedly connected to the side of the connecting frame 2. Threaded sleeves 312 are fixedly connected to the inner walls of the two side frames 311. Threaded rods 313 are threadedly connected to the inner walls of the threaded sleeves 312. A handle 314 is fixedly connected to one end of the threaded rod 313, and a connector 315 is fixedly connected to the other end of the threaded rod 313. A round rod 316 is fixedly connected to the surface of the connector 315 away from the threaded rod 313.

[0029] The engagement component 33 includes an inner frame 331 fixedly connected to the inner side of the connecting frame 2. Both sides of the inner frame 331 are provided with sliding grooves 332. An engagement buckle 334 is fixedly connected to the inner bottom wall of the inner frame 331. A crossbar 333 is slidably connected to the inner wall of the sliding groove 332. The end of the crossbar 333 passes through the sliding groove 332 and extends to the outside of the inner frame 331.

[0030] In this embodiment, the device engages with the snap fastener 334 at the lower end of the horizontal frame 333 during disassembly and assembly, which facilitates the pulling operation of the motor components. During the pulling operation, the knob handle 314 drives the threaded rod 313 to rotate, which in turn, in conjunction with the threaded sleeve 312, causes the threaded rod 313 to move horizontally. The connecting head 315 drives the round rod 316 to move, thereby adjusting the position of the motor and performing the pulling and disassembly operation.

[0031] Working principle: During disassembly and assembly, the lower end of the crossbar 333 engages with the snap fastener 334 to form a bite. The knob handle 314 drives the threaded rod 313 to move horizontally. The connector 315 drives the round rod 316 to move. The support plate 325 holds the motor in place. The bolts at both ends of the support plate 325 extend to the external bolts of the side groove 324 for positioning. This limits the support plate 325 from easily shaking when supporting the motor. The slotted hole 326 is used for positioning the fixing connection. Through the cooperation of multiple side grooves 324 and the support plate 325, the support position is adjusted according to different motor models. Under the guidance of the sliding seat 323, it works with the guide groove 11 to form a good guiding effect.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
