[0003] When the bearing is running, the rollers roll between the inner and outer rings, converting sliding friction into rolling friction, greatly reducing the frictional resistance. The size of the rollers determines the size of the bearing. In the prior art, when screening the rollers, different aperture-sized sieve plates are replaced to achieve the screening purpose. The accumulation of too many sieve plates occupies space, and it is time-consuming and laborious to replace the sieve plates, with low efficiency. Moreover, when screening, a single-layer sieve plate is used for screening, and it is difficult to make all the screened rollers meet the requirements, requiring multiple screenings, which increases the production cost.

[0019] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.
[0020] As Figures 1-4 shown, the utility model provides a technical solution: a roller screening and detecting device for bearing manufacturing, including a screening box 1. A vibrator 4 is fixedly connected to one side of the screening box 1. Four bases 3 are fixedly connected to the bottom of the screening box 1. The base 3 includes a slide bar 31 and a support seat 32. An elastic space 34 is opened in the support seat 32. A spring 33 is arranged in the elastic space 34. Two ends of the spring 33 are respectively fixedly connected to the bottom of the slide bar 31 and the inner bottom of the support seat 32. The slide bar 31 is slidably connected with the support seat 32. Under the vibration of the vibrator 4, the base 3 supports the screening box 1, and the spring 33 provides a continuous buffering effect on the slide bar 31, which can avoid the sound caused by the direct contact between the slide bar 31 and the ground and is easy to damage the device after a long time.
[0021] Six chutes 12 are arranged on the side wall of the screening box 1, and the six chutes 12 are paired in two to form three groups. The chutes 12 are arranged in an inclined state. The lower sieve plate 16 is fixedly connected to the inner bottom of the chutes 12. An upper sieve plate 15 is slidably connected in the chutes 12. The upper sieve plate 15 and the lower sieve plate 16 form a group. Three groups are arranged in the screening box 1 from top to bottom. The size of the communicating part between the upper sieve holes 17 and the lower sieve holes 18 decreases successively from top to bottom. Under the action of the chutes 12, both the upper sieve plate 15 and the lower sieve plate 16 are in an inclined state. Under the action of the self-gravity of the bearing rollers and the vibration of the vibrator 4, the rollers move towards the lower parts of the upper sieve plate 15 and the lower sieve plate 16.
[0022] The upper sieve plate 15 is located above the lower sieve plate 16. Three plate grooves 9 are opened on one side of the screening box 1. The upper sieve plate 15 is slidably connected with the plate grooves 9. A plurality of upper sieve holes 17 and lower sieve holes 18 which are evenly distributed are respectively opened on the upper sieve plate 15 and the lower sieve plate 16. The upper sieve holes 17 and the lower sieve holes 18 are vertically corresponding to each other. The size of the communicating part between the upper sieve holes 17 and the lower sieve holes 18 is used to screen the size of the rollers. By the limit sliding of the upper sieve plate 15, the size of the communicating part between the upper sieve holes 17 and the lower sieve holes 18 is adjusted, and the plate grooves 9 provide a place for the sliding of the upper sieve plate 15.
[0023] An upper observation hole 20 and a rack 19 are provided on the upper sieve plate 15. One side of the lower sieve plate 16 is fixedly connected with an observation plate 14, and a lower observation hole 21 is provided on the observation plate 14. The mutual cooperation of the rack 19 and the gear 11 provides power for the sliding of the upper sieve plate 15. The communication part of the upper observation hole 20 and the lower observation hole 21 corresponds to the communication part of the upper sieve hole 17 and the lower sieve hole 18. Thus, the size of the internal screening rollers of the screening box 1 can be judged by actually measuring the sizes of the upper observation hole 20 and the lower observation hole 21.
[0024] One side of the top of the screening box 1 is fixedly connected with a feeding cylinder 2. Two slats 5 are fixedly connected to one side of the screening box 1. Three rotating rods 10 are inserted on the slats 5. A gear 11 is fixedly connected to the rotating rod 10. One end of the rotating rod 10 penetrates through the slat 5 and is fixedly connected with a turntable 13. Three discharge ports 6 are provided on one side of the screening box 1. The inner bottom of the screening box 1 is slidably connected with a storage box 7. One side of the storage box 7 is fixedly connected with a handrail 8.
[0025] The slats 5 provide a supporting function for the rotating rods 10, enabling the rotating rods 10 to rotate under the action of the turntable 13. The meshing of the gear 11 and the rack 19 drives the upper sieve plate 15 to move, thereby adjusting the aperture size of the screening rollers. Since the feeding cylinder 2 is arranged on one side of the top of the screening box 1 facing the slats 5, it can prevent the rollers from entering the screening box 1 and affecting the screening results due to insufficient rolling distance of the rollers.
[0026] The working principle of the present utility model is as follows: Before use, first rotate the turntable 13 to adjust the size of the communication part between the upper sieve hole 17 and the lower sieve hole 18 inside the screening box 1. Determine whether the size of the communication part between the internal upper sieve hole 17 and the lower sieve hole 18 meets the requirements through the upper observation hole 20 and the lower observation hole 21 on the outside of the screening box 1. Pour the rollers to be screened and detected into the screening box 1 through the feeding cylinder 2. At this time, the vibrator 4 is started. Under the action of the vibrator 4 and the self-gravity of the rollers, the rollers roll on the upper sieve plate 15 at the top. The rollers smaller than or equal to the screening size enter the next layer, and the too-large rollers enter the outside of the screening box 1 through the discharge port 6. After the rollers in the second layer are screened, those smaller than the size of the communication part between the upper sieve hole 17 and the lower sieve hole 18 in the first layer enter the third layer. The rollers that meet the standard in the first layer enter the outside of the screening box 1 through the second discharge port 6. After the rollers in the third layer are screened, they enter the storage box 7. The rollers that meet the standard in the second layer enter the outside of the screening box 1 through the third discharge port 6. This device screens out the rollers required in the first layer through two-stage screening.
