Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 A sieving device for stator laminations and rotor laminations includes a base plate 1, a first support plate 2 fixedly connected to the top of the base plate 1 by a support leg, a rectangular hole 3 penetrating the outer wall of the first support plate 2, a first adjustment mechanism provided on the upper end face of the first support plate 2, a second support plate 13 fixedly connected to the lower end face of the first support plate 2 by a support leg, and a second adjustment mechanism located above the second support plate 13 provided inside the first support plate 2.

[0025] The first adjustment mechanism includes a first threaded rod 4 rotatably connected to the top of the first support plate 2 via an ear plate. Both ends of the outer wall of the first threaded rod 4 are threaded with symmetrically distributed first limiting plates 5, and the lower end surfaces of the two first limiting plates 5 abut against the upper end surfaces of the first support plate 2.

[0026] In this embodiment: rotating the first threaded rod 4 causes the two first limiting plates 5 to move relative to or away from each other along the first limiting rod 11, thereby facilitating the adjustment of the distance between the two first limiting plates 5 according to the outer diameter of the rotor laminations. The mixed stator laminations and rotor laminations are placed on the higher side of the first support plate 2, and the stator laminations and rotor laminations slide downwards. The larger rotor laminations slide down from above the two sliding plates 7, and the smaller stator laminations fall down onto the second support plate 13 through the gap between the two sliding plates 7. If the stator laminations are not in the center of the rectangular hole 3, the stator laminations can still fall downwards under unbalanced force, resulting in good performance.

[0027] As a technical optimization of this utility model, the second adjustment mechanism includes two symmetrically distributed slide plates 7, and two sliders 8 are fixedly connected to both ends of the two slide plates 7. The inner wall of the first support plate 2 has two symmetrically distributed grooves 6. The four sliders 8 are slidably connected to the two grooves 6 respectively. A second threaded rod 10 is rotatably connected inside one of the grooves 6. The two slide plates 7 are respectively threaded to both ends of the second threaded rod 10 through the sliders 8.

[0028] In this embodiment: rotating the second threaded rod 10 causes the two sliding plates 7 to move relative to or away from each other along the second limiting rod 12 via the slider 8, thereby facilitating the adjustment of the distance between the two sliding plates 7 and the two second limiting plates 9 according to the outer diameter of the stator lamination, which is highly practical.

[0029] As a technical optimization of this utility model, the lower end surfaces of the two slide plates 7 are fixedly connected with the second limiting plate 9, and the lower end surfaces of the two second limiting plates 9 abut against the upper end surface of the second support plate 13.

[0030] In this embodiment, two second limiting plates 9 are used to limit the stator segments that fall onto the second support plate 13, so that the stator segments can slide down stably.

[0031] As a technical optimization of this utility model, the first adjustment mechanism also includes a first limiting rod 11 fixedly connected to the top of the first support plate 2 via an ear plate, and both first limiting plates 5 are slidably connected to the first limiting rod 11.

[0032] In this embodiment: the first limiting rod 11 facilitates the limiting of the two first limiting plates 5, so that the first limiting plates 5 move back and forth stably.

[0033] As a technical optimization of this utility model, a second limiting rod 12 is fixedly connected inside another slide groove 6, and both slide plates 7 are slidably connected to the second limiting rod 12 through a slider 8.

[0034] In this embodiment, the second limiting rod 12 facilitates the limiting of the two slide plates 7, making the forward and backward movement of the slide plates 7 stable.

[0035] As a technical optimization of this utility model, the upper ends of the two first limiting plates 5 and the upper ends of the two second limiting plates 9 are all trumpet-shaped.

[0036] In this embodiment: by setting the upper end of the two first limiting plates 5 in a trumpet shape, it is easy for the rotor laminations to move to the center of the first support plate 2; by setting the upper end of the two second limiting plates 9 in a trumpet shape, it is easy for the stator laminations to move to the center of the second support plate 13.

[0037] As a technical optimization of this utility model, a first collection box 14 is provided at the lower end of the first support plate 2, and a second collection box 15 is provided at the lower end of the second support plate 13.

[0038] In this embodiment: the first collection box 14 facilitates the collection of rotor laminations, and the second collection box 15 facilitates the collection of stator laminations.

[0039] The working principle and usage process of this utility model are as follows: Before use, firstly rotate the first threaded rod 4. The first threaded rod 4 drives the two first limiting plates 5 to move relative to or away from each other along the first limiting rod 11, which facilitates the adjustment of the distance between the two first limiting plates 5 according to the outer diameter of the rotor laminations. Then, rotate the second threaded rod 10. The second threaded rod 10 drives the two sliding plates 7 to move relative to or away from each other along the second limiting rod 12 through the slider 8, which facilitates the adjustment of the distance between the two sliding plates 7 and the two second limiting plates 9 according to the outer diameter of the stator laminations. After the adjustment is appropriate, place the mixed stator laminations and rotor laminations on the higher side of the first support plate 2. The stator laminations and rotor laminations slide downwards. The larger rotor laminations slide down from above the two sliding plates 7, and the smaller stator laminations fall down from the gap between the two sliding plates 7 onto the second support plate 13. If the stator laminations are not in the center of the rectangular hole 3, the stator laminations can still fall downwards under unbalanced force, resulting in good performance.
