[0006] Furthermore, connecting rods one are fixedly connected to the outer walls of the plurality of first rotating shafts, the plurality of connecting rods one are respectively rotatably connected to the plurality of second rotating shafts, and clamping wheels are rotatably connected to the plurality of connecting rods one.

[0007] Furthermore, a turntable is rotatably connected to the front side of the fixed ring, a first connecting block is fixedly connected to the front side of the turntable, a threaded rod is rotatably connected to the middle axis of the first connecting block, and the bottom of the threaded rod penetrates through the first connecting block.

[0008] Further, a handle is fixedly connected to the extending portion of the threaded rod. A connecting plate is fixedly connected to the outer wall of the rotating ring. A second connecting block is rotatably connected to the front side of the fixed ring. The top of the threaded rod penetrates through the second connecting block, and the threaded rod is threadedly connected to the second connecting block.

[0009] Further, a first spring is sleeved on the outer wall of the threaded rod. The top of the first spring is fixedly connected to the second connecting block, and the bottom of the first spring is fixedly connected to the first connecting block. A rotor shaft is arranged in the motor housing. A plurality of clamping wheels are all in contact with the rotor shaft, and the rotor shaft is fixedly connected to the rotor.

[0010] Further, a first limiting groove is formed in the motor housing. A plurality of limiting rods are fixedly connected to the mounting plate. Two fixing plates are respectively fixedly connected to the inner walls of the plurality of limiting rods.

[0011] Further, a plurality of push rods are slidably connected to the inner walls of the plurality of fixing plates.

Two limiting balls are respectively arranged on the plurality of limiting rods, and the plurality of limiting balls are respectively adapted to the plurality of second limiting grooves.

[0013] The present invention has the following beneficial effects: 1. In the present invention, the rotor is fixed inside the motor housing. When fixing, the rotor shaft and the rotor are placed inside the motor housing, and then the handle is rotated. When the handle rotates, the threaded rod will also rotate on the first connecting block. When the threaded rod rotates, it will drive the second connecting block to slide on its outer wall through the thread. When the second connecting block moves, it will drive the connecting plate to move accordingly. At the same time, the rotating ring will be driven by the connecting plate to move. When the rotating ring moves, it will drive the first connecting rod to move accordingly. At this time, due to the limitation of the second rotating shaft and the first rotating shaft, the first connecting rod can only change its angle. When the first connecting rod changes its angle, the clamping wheel will also be driven accordingly, so as to move closer to each other. As the clamping wheels move closer to each other, they will come into contact with the rotor shaft. At this time, stop rotating the handle. As the first connecting block and the second connecting block rotate, they will move away from each other. As the first connecting block and the second connecting block move away from each other, the first spring will be pulled. As the pulling force of the first spring pulls the second connecting block and the first connecting block closer to each other, the effect of preventing reverse rotation can be achieved at this time. After the clamping wheel contacts the rotor shaft, the rotor shaft can be fixed. Thus, the rotor shaft can also be fixed by the mutual approach of the clamping wheels, and the effect of adapting to rotor shafts of different sizes can also be achieved. The adjustable fixing method enables the same set of fixing devices to be used for a variety of motors with different specifications, improving the versatility and applicability of the equipment, and reducing the production cost and inventory pressure of enterprises.

[0014] 2. In the present invention, after the rotor shaft and the rotor are fixed, the mounting plate can be installed on the motor housing. When installing, insert the limiting rod into the motor housing. When inserting, press the push rod. At this time, the push rod will drive the sliding plate to slide towards the side close to the motor housing. As the sliding plate slides, it will cooperate with the two push rods to squeeze and stretch the two second springs. When the sliding plate slides into the motor housing, it can stretch the side far from the motor housing and also squeeze the second spring close to the motor housing. As the connecting rod two of the push rod also moves accordingly, as the connecting rod two moves, the limiting ball will slide into the second limiting groove. At this time, the limiting ball will be received into the limiting rod. Then continue to push the mounting plate until the mounting plate contacts the motor housing. After contact, stop pressing the push rod. Then the two second springs will reset the sliding plate and the push rod. At this time, the limiting ball will be pushed by the second limiting groove again and slide out of the limiting rod. At this time, the limiting ball will be limited in the first limiting groove, so as to achieve the effect of limiting the limiting rod. The same mounting plate and limiting device can be used for installation, improving the versatility and applicability of the equipment, and reducing the production cost and inventory pressure of enterprises.

[0015] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0020] Please refer to Figures 1 - 8As shown in the figure, the present invention is a brushless motor rotor, which includes a motor housing 1. There are two adjusting mechanisms 2 and an installation mechanism 3 arranged on the motor housing 1. A number of stators 101 are fixedly connected to the inner wall of the motor housing 1. A rotor 102 is arranged inside the motor housing 1. The adjusting mechanism 2 includes a fixed ring 211 fixedly connected to the inner wall of the motor housing 1. A rotating ring 212 is rotatably connected to the front side of the fixed ring 211. A number of first rotating shafts 213 are rotatably connected to the front side of the fixed ring 211. A number of second rotating shafts 214 are rotatably connected to the rotating ring 212. Connecting rods 215 are fixedly connected to the outer walls of the first rotating shafts 213. The connecting rods 215 are respectively rotatably connected to the second rotating shafts 214. At the same time, the rotating ring 212 is driven to move by a connecting plate 2111. When the rotating ring 212 moves, it will drive the connecting rods 215 to move accordingly. At this time, due to the limitation of the second rotating shafts 214 and the first rotating shafts 213, the connecting rods 215 can only change their angles. Clamping wheels 216 are rotatably connected to the connecting rods 215. A turntable 217 is rotatably connected to the front side of the fixed ring 211. A first connecting block 218 is fixedly connected to the front side of the turntable 217. A threaded rod 219 is rotatably connected to the central axis of the first connecting block 218. The bottom of the threaded rod 219 penetrates through the first connecting block 218. A handle 2110 is fixedly connected to the extending part of the threaded rod 219.Rotate the handle 2110. When the handle 2110 rotates, the threaded rod 219 will also rotate on the first connecting block 218. A connecting plate 2111 is fixedly connected to the outer wall of the rotating ring 212. A second connecting block 2112 is rotatably connected to the front side of the fixed ring 211. The top of the threaded rod 219 passes through the second connecting block 2112, and the threaded rod 219 is threadedly connected to the second connecting block 2112. When the threaded rod 219 rotates, it will drive the second connecting block 2112 to slide on its outer wall through the thread. When the second connecting block 2112 moves, it will drive the connecting plate 2111 to move accordingly. A first spring 2113 is sleeved on the outer wall of the threaded rod 219. The top of the first spring 2113 is fixedly connected to the second connecting block 2112, and the bottom of the first spring 2113 is fixedly connected to the first connecting block 218. As the first connecting block 218 and the second connecting block 2112 rotate, they will move away from each other. As the first connecting block 218 and the second connecting block 2112 move away from each other, the first spring 2113 will be stretched. As the pulling force of the first spring 2113 pulls the second connecting block 2112 and the first connecting block 218 to move closer to each other, the effect of preventing reverse rotation can be achieved at this time. A rotor shaft 2114 is arranged in the motor housing 1. A plurality of clamping wheels 216 are all in contact with the rotor shaft 2114. When the first connecting rod 215 changes its angle, the clamping wheels 216 will also be driven accordingly and move closer to each other. As the clamping wheels 216 move closer to each other, they will come into contact with the rotor shaft 2114. After the clamping wheels 216 come into contact with the rotor shaft 2114, the effect of fixing the rotor shaft 2114 can be achieved. Thus, the clamping wheels 216 can also be fixed by moving closer to each other to achieve the effect of adapting to rotor shafts 2114 of different sizes. The rotor shaft 2114 is fixedly connected to the rotor 102. By setting the adjusting mechanism 2, the adjustable fixing method enables the same set of fixing devices to be used for motors of multiple different specifications, improving the versatility and applicability of the equipment and reducing the production cost and inventory pressure of the enterprise.,

[0021] The mounting mechanism 3 includes a mounting plate 311 provided on the front side of the motor housing 1. The mounting plate 311 extends into the motor housing 1. A first limiting groove 312 is formed in the motor housing 1. A plurality of limiting rods 313 are fixedly connected to the mounting plate 311. Two fixing plates 314 are respectively fixedly connected to the inner walls of the plurality of limiting rods 313. A plurality of push rods 315 are slidably connected to the inner walls of the plurality of fixing plates 314. Slide plates 316 are fixedly connected to the outer walls of the plurality of push rods 315. Two second springs 317 are respectively sleeved on the outer walls of the plurality of push rods 315. The mutually remote sides of the plurality of second springs 317 are respectively fixedly connected to the plurality of fixing plates 314. The mutually close sides of the plurality of second springs 317 are respectively fixedly connected to the plurality of slide plates 316. When the push rods 315 are pressed during insertion, at this time, the push rods 315 will drive the slide plates 316 to slide towards the side close to the motor housing 1. As the slide plates 316 slide, they will cooperate with the two push rods 315 to squeeze and stretch the two second springs 317. When the slide plates 316 slide into the motor housing 1, the side far from the motor housing 1 can be stretched, and the second springs 317 close to the motor housing 1 can also be squeezed. Connecting rods two 318 are fixedly connected to the rear sides of the plurality of push rods 315. Second limiting grooves 319 are formed in the plurality of connecting rods two 318. Two limiting balls 3110 are respectively arranged on the plurality of limiting rods 313. As the connecting rods two 318 of the push rods 315 move accordingly, as the connecting rods two 318 move, the limiting balls 3110 will slide into the second limiting grooves 319. At this time, the limiting balls 3110 will be received into the limiting rods 313. The plurality of limiting balls 3110 respectively match the plurality of second limiting grooves 319. After contact, stop pressing the push rods 315. Subsequently, the two second springs 317 will reset the slide plates 316 and the push rods 315. At this time, the limiting balls 3110 will be pushed by the second limiting grooves 319 again and slide out of the limiting rods 313. At this time, the limiting balls 3110 will be limited in the first limiting groove 312, so as to achieve the effect of limiting the limiting rods 313. By providing the mounting mechanism 3, the same mounting plate and limiting device can be used for mounting, improving the versatility and applicability of the equipment, and reducing the production cost and inventory pressure of the enterprise.

[0022] In use, first fix the rotor 102 inside the motor housing 1. When fixing, place the rotor shaft 2114 and the rotor 102 inside the motor housing 1. Then rotate the handle 2110. When the handle 2110 rotates, the threaded rod 219 will also rotate on the first connecting block 218. When the threaded rod 219 rotates, it will drive the second connecting block 2112 to slide on its outer wall through the thread. When the second connecting block 2112 moves, it will drive the connecting plate 2111 to move accordingly. At the same time, the rotating ring 212 will be driven by the connecting plate 2111 to move. When the rotating ring 212 moves, it will drive the first connecting rod 215 to move. At this time, due to the restrictions of the second rotating shaft 214 and the first rotating shaft 213, the first connecting rod 215 can only change its angle. When the first connecting rod 215 changes its angle, the clamping wheel 216 will also be driven accordingly, so as to move closer to each other. As the clamping wheels 216 move closer to each other, they will contact the rotor shaft 2114. At this time, stop rotating the handle 2110. As the first connecting block 218 and the second connecting block 2112 rotate, they will move away from each other. As the first connecting block 218 and the second connecting block 2112 move away from each other, the first spring 2113 will be pulled. As the pulling force of the first spring 2113 pulls the second connecting block 2112 and the first connecting block 218 to move closer to each other, the effect of preventing reverse rotation can be achieved at this time. After the clamping wheel 216 contacts the rotor shaft 2114, the effect of fixing the rotor shaft 2114 can be achieved. Thus, the rotor shaft 2114 of different sizes can also be fixed by the mutual approach of the clamping wheels 216, so as to achieve the effect of adapting to different sizes of the rotor shaft 2114. After the rotor shaft 2114 and the rotor 102 are fixed, the mounting plate 311 can be installed on the motor housing 1. When installing, insert the limiting rod 313 into the motor housing 1. When inserting, press the push rod 315. At this time, the push rod 315 will drive the sliding plate 316 to slide towards the side close to the motor housing 1 accordingly. As the sliding plate 316 slides, it will cooperate with the two push rods 315 to squeeze and stretch the two second springs 317. When the sliding plate 316 slides into the motor housing 1, it can stretch the side away from the motor housing 1 and also squeeze the second spring 317 close to the motor housing 1. As the connecting rod 318 of the push rod 315 also moves accordingly, as the connecting rod 318 moves, the limiting ball 3110 will slide into the second limiting groove 319. At this time, the limiting ball 3110 will be received into the limiting rod 313. Then continue to push the mounting plate 311 until the mounting plate 311 contacts the motor housing 1. After contact, stop pressing the push rod 315. Then the two second springs 317 will reset the sliding plate 316 and the push rod 315. At this time, the limiting ball 3110 will be pushed by the second limiting groove 319 again and slide out of the limiting rod 313. At this time, the limiting ball 3110 will be limited in the first limiting groove 312, so as to achieve the effect of limiting the limiting rod 313.
