During operation, when it is necessary to fix the rotor, the rotor can be sleeved on the rotating rod 2, and then the rotating handle 301 can be rotated so that the rotating handle 301 drives the threaded rod 3 to rotate, and then the threaded rod 3 and the threaded block 4 cooperate with each other to drive the threaded block 4 to slide inside the rotating rod 2, and then the clamping block 5 is pushed by the inclined push block 401, so that the clamping block 5 slides to a position close to one side of the rotor, and the rotor is squeezed and fixed by the clamping block 5, which can make the rotor more stable on the rotating rod 2. At the same time, the clamping block 5 is pushed by the threaded block 4 and the inclined push block 401, which can make the clamping block 5 slide to one side of the rotor at the same time, so that the rotor can be better arranged concentrically with the center of the circle of the rotating rod 2, and the device can be adapted to fix rotors of more sizes by pushing and fixing the clamping block 5.
[0025] Reference Figures 2 to 3 As shown, a positioning rod 6 is fixedly connected to the side wall of the clamping block 5; the positioning rod 6 is slidably connected to the internal position of the rotating rod 2; during operation, when the clamping block 5 is sliding, the sliding of the positioning rod 6 is restricted by the rotating rod 2, so that the clamping block 5 is less likely to tilt during the sliding process, making the sliding of the clamping block 5 more stable.
[0026] Reference Figure 3As shown, an anti-slip block 7 is fixedly connected to the end of the positioning rod 6; the anti-slip block 7 is arranged at one end of the anti-slip block 7 away from the clamping block 5; the anti-slip block 7 is slidably connected to the internal position of the rotating rod 2; during operation, when the positioning rod 6 slides inside the rotating rod 2, the anti-slip block 7 is blocked by the rotating rod 2, which can effectively prevent the positioning rod 6 from being separated from the rotating rod 2, causing the clamping block 5 to be separated from the rotating rod 2.
[0027] Reference Figures 2 to 4 As shown, a plurality of guide rods 8 are fixedly connected to the interior of the rotating rod 2; the guide rods 8 are arranged at positions corresponding to the inclined push blocks 401; the inclined push blocks 401 are slidably connected to the guide rods 8; the guide rods 8 are arranged in parallel with the threaded rods 3; during operation, when the threaded block 4 slides inside the rotating rod 2, the sliding of the threaded block 4 is restricted by setting the guide rods 8, so that the threaded block 4 is less likely to tilt during the sliding process, and the sliding of the threaded block 4 is more stable, so that the inclined push block 401 can push the clamping block 5 better.
[0028] Reference Figure 2 and Figure 4 As shown, the interior of the tilted push block 401 is rotatably connected with an anti-wear roller 9; the side wall of the anti-wear roller 9 contacts the side wall of the clamping block 5; during operation, when the tilted push block 401 pushes the clamping block 5, by arranging the anti-wear roller 9 inside the tilted push block 401, the sliding friction between the tilted push block 401 and the clamping block 5 can be converted into rolling friction, so that the friction force between the tilted push block 401 and the clamping block 5 is smaller, thereby reducing the wear between the tilted push block 401 and the clamping block 5.
[0029] Reference Figure 2 As shown, an anti-skid pad 10 is fixedly connected to the side wall of the clamping block 5; the anti-skid pad 10 is arranged at a position of the clamping block 5 away from the rotating rod 2; during operation, when the clamping block 5 squeezes and fixes the rotor, by arranging the anti-skid pad 10 on the side wall of the clamping block 5, the contact area between the clamping block 5 and the rotor can be made larger, so that the clamping block 5 can better fix the rotor.
[0030] Reference Figure 4 As shown, a positioning block 11 is fixedly connected to the threaded rod 3; the positioning block 11 is rotatably connected to the internal position of the rotating rod 2; during operation, when the threaded rod 3 rotates inside the rotating rod 2, the rotation of the positioning block 11 is restricted by the rotating rod 2, so that the threaded rod 3 is less inclined during the rotation process, and the threaded rod 3 is more stable when rotating.
[0031] Reference Figure 4As shown, a plurality of balls 12 are arranged between the rotating rod 2 and the positioning block 11; the side walls of the balls 12 are in contact with the side walls of the rotating rod 2 and the positioning block 11; during operation, when the positioning block 11 rotates inside the rotating rod 2, by arranging the balls 12 between the positioning block 11 and the rotating rod 2, the sliding friction between the rotating rod 2 and the positioning block 11 can be converted into rolling friction, so that the friction force between the rotating rod 2 and the positioning block 11 is smaller, thereby reducing the wear between the rotating rod 2 and the positioning block 11.
[0032] Working principle: when the rotor needs to be fixed, the rotor can be sleeved on the rotating rod 2, and then the rotating handle 301 can be rotated, so that the rotating handle 301 drives the threaded rod 3 to rotate, and then the threaded rod 3 and the threaded block 4 are matched with each other to drive the threaded block 4 to slide inside the rotating rod 2, and then the clamping block 5 is pushed by the inclined push block 401, so that the clamping block 5 slides to a position close to one side of the rotor. The rotor is squeezed and fixed by the clamping block 5, which can make the rotor more stable on the rotating rod 2. At the same time, the clamping block 5 is pushed by the threaded block 4 and the inclined push block 401, so that the clamping block 5 can slide to one side of the rotor at the same time, so that the rotor can be better arranged concentrically with the center of the circle of the rotating rod 2. The push and fixation of the clamping block 5 can also make the device adapt to the fixation of rotors of more sizes.
[0033] When the pressing block 5 is sliding, the sliding of the positioning rod 6 is restricted by the rotating rod 2, so that the pressing block 5 is less likely to tilt during the sliding process, and the sliding of the pressing block 5 is more stable.
[0034] When the positioning rod 6 slides inside the rotating rod 2, the rotating rod 2 blocks the anti-detachment block 7, which can effectively prevent the positioning rod 6 from detaching from the rotating rod 2, causing the clamping block 5 to detach from the rotating rod 2.
[0035] When the threaded block 4 slides inside the rotating rod 2, the sliding of the threaded block 4 is restricted by setting the guide rod 8, so that the threaded block 4 is less likely to tilt during the sliding process, and the sliding of the threaded block 4 is more stable, so that the inclined push block 401 can push the clamping block 5 better.
[0036] When the tilting push block 401 pushes the clamping block 5, by arranging the anti-wear roller 9 inside the tilting push block 401, the sliding friction between the tilting push block 401 and the clamping block 5 can be converted into rolling friction, so that the friction force between the tilting push block 401 and the clamping block 5 is smaller, thereby reducing the wear between the tilting push block 401 and the clamping block 5.
[0037] When the pressing block 5 is used to squeeze and fix the rotor, by providing an anti-skid pad 10 on the side wall of the pressing block 5 , the contact area between the pressing block 5 and the rotor can be made larger, so that the pressing block 5 can better fix the rotor.
[0038] When the threaded rod 3 rotates inside the rotating rod 2, the rotating rod 2 limits the rotation of the positioning block 11, so that the threaded rod 3 is less inclined during the rotation process, and the threaded rod 3 is more stable during the rotation.
[0039] When the positioning block 11 rotates inside the rotating rod 2, by arranging the ball 12 between the positioning block 11 and the rotating rod 2, the sliding friction between the rotating rod 2 and the positioning block 11 can be converted into rolling friction, so that the friction force between the rotating rod 2 and the positioning block 11 is smaller, thereby reducing the wear between the rotating rod 2 and the positioning block 11.
[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
