Description

Technical Field

[0001] This utility model relates to the field of bearing steel ball screening, and in particular to an adaptive aperture bearing steel ball vibrating screening device. Background Technology

[0002] As the core component of a bearing, the dimensional accuracy and surface quality of bearing steel balls directly affect the bearing's rotational accuracy, load-bearing capacity, and service life. During the production and processing of steel balls, it is necessary to use a screening device to efficiently classify steel balls of different diameters to meet the stringent requirements of downstream assembly.

[0003] Refer to the bearing steel ball filter device (application number: 2020212180114). This application uses a cam that is driven by a motor to rotate two cams synchronously, thereby causing the screen plate to reciprocate in the vertical direction. This causes the bearing steel balls inside the screening shell to be continuously vibrated, so that qualified bearing steel balls fall to the bottom of the inner side of the screening shell for subsequent conveying.

[0004] However, when this application is used, larger diameter steel balls may get stuck directly in the screen holes. When steel balls are continuously fed, they are prone to accumulate, which can lead to screen blockage. Frequent manual intervention is required to clean them, which increases production costs. It is also difficult to achieve adjustable screen holes to facilitate the classification and screening of steel balls of different sizes.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an adaptive aperture bearing steel ball vibrating screen device to solve the aforementioned technical defects.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1 - Figure 5 As shown, this utility model is an adaptive aperture bearing steel ball vibrating screening device, including a classification storage box 1. The classification storage box 1 has symmetrically distributed partitions 11 inside, and the partitions 11 are all fixedly connected to the classification storage box 1. The partitions 11 divide the classification storage box 1 into three compartments: storage compartment one 12, storage compartment two 16, and storage compartment three 17. Storage compartment one 12 is used to store bearing steel balls with smaller size, storage compartment two 16 is used to store bearing steel balls with appropriate size, and storage compartment three 17 is used to store bearing steel balls with larger size. Slide grooves 13 are opened on both sides of the upper part of the classification storage box 1. One end of the classification storage box 1 is also provided with symmetrically distributed lead screw motors 14, and the lead screw motors 14 are all fixedly connected to the classification storage box 1. The drive shaft of the lead screw motor 14 extends into the slide groove 13 and is fixedly connected to a ball screw 15. The threads on the outer side of the ball screw 15 are not shown in the figure.

[0026] An adjustable screening mechanism 2 is provided above the classification storage box 1. The adjustable screening mechanism 2 includes symmetrically distributed base frames 21. The base frames 21 are located above the classification storage box 1 and are slidably connected to the classification storage box 1. Symmetrically distributed connecting plates 22 are fixedly provided between the base frames 21. A screw slider 23 is fixedly connected below each base frame 21. The screw slider 23 is located in the slide groove 13 and is threadedly connected to the ball screw 15. When the screw motor 14 is started, it drives the ball screw 15 to rotate. The ball screw 15 drives the screw slider 23 to move horizontally within the slide groove 13.

[0027] Above the base frame 21, there are arrayed spring shock absorbers 24. The lower ends of the spring shock absorbers 24 are all fixed to the base frame 21 by bolts. Above the base frame 21, there is also a screening frame 25. The lower end of the screening frame 25 is fixed to the upper end of the spring shock absorbers 24 by bolts. Below the screening frame 25, there are symmetrically distributed extension plates 28. The inside of the extension plates 28 is provided with a rotatably connected hand-tightening screw 29. Above the screening frame 25, an extension frame 26 is fixed by bolts. Above the extension frame 26, there are symmetrically distributed vibration motors 27. When the vibration motors 27 are started, they provide vibration force to the screening frame 25.

[0028] The screening rack 25 has an array of screening slots 30 inside. Each screening rack 25 on one side of the screening slot 30 has an embedded slot 31. Each embedded slot 31 has a slidingly connected adjusting plate 32 inside. Below the adjusting plate 32 is a fixedly connected connecting strip. Below the connecting strip is a fixedly connected nut 33. The nut 33 is located outside the hand-tightening screw 29 and is threadedly connected to the hand-tightening screw 29.

[0029] The working process and principle of this utility model are as follows:

[0030] In use, first tighten the hand screw 29 so that the distance between the adjusting plate 32 and the inner wall of the screening tank 30 is less than the size of the qualified product. At this time, start the lead screw motor 14. When the lead screw motor 14 starts, it drives the ball screw 15 to rotate. The ball screw 15 drives the adjustable screening mechanism 2 above it to move horizontally to the top of the storage chamber 12. At this time, pour down the bearing steel balls to be screened and start the vibration motor 27. When the vibration motor 27 starts, it drives the screening frame 25 to vibrate, so that the steel balls in the screening frame 25 that are smaller than the standard value fall through the gap between the screening tank 30 and the adjusting plate 32 into the storage chamber 12 for storage.

[0031] After screening, qualified steel balls and larger diameter steel balls remain in the screening rack 25. The screw motor 14 is started again to move the adjustable screening mechanism 2 above the storage chamber 2 16. Then, the hand screw 29 is turned until the distance between the adjusting plate 32 and the screening groove 30 is equal to the length of the qualified steel ball diameter. The vibration motor 27 is then started to screen the steel balls in the screening rack 25 until the standard steel balls in the screening rack 25 fall through the gap between the screening groove 30 and the adjusting plate 32 into the storage chamber 2 16 for storage. The screw motor 14 is then started again to move the adjustable screening mechanism 2 above the storage chamber 3 17. The hand screw 29 is turned to retract the adjusting plate 32 into the embedded groove 31. At this time, the steel balls in the screening rack 25 fall through the gap in the screening groove 30 into the storage chamber 3 17 for storage, thus completing the classification and vibration screening operation of the bearing steel balls.
