Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel ball production and processing, and in particular to a steel ball screening device for steel ball production and processing. Background Technology
[0002] Steel ball sorting is a crucial quality control step in steel ball production. Equipment such as vibrating screens and drum screens sorts steel balls according to diameter and precision grade. Vibrating screens separate steel balls of different sizes based on differences in screen aperture, while drum screens use a stepped structure within a rotating drum for screening. In some high-precision applications, optical inspection equipment is required to remove steel balls with excessive ellipticity. After sorting, the steel balls are categorized according to tolerance grades to ensure suitability and stability for applications such as bearings and precision instruments.
[0003] Although existing screening devices can process steel balls, they typically separate steel balls of different sizes by utilizing differences in screen mesh size. When the steel balls fall, they impact the screen mesh, which can easily cause the mesh to deform. This not only requires replacing the screen mesh, but the replacement process also affects continuous production. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel ball screening device for steel ball production and processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A steel ball screening device for steel ball production and processing includes a housing, a plurality of discharge ports connected to the housing, two studs connected to each of the plurality of discharge ports, and plates rotatably connected to each of the plurality of studs. Each pair of corresponding plates is designed to gradually expand, and threaded sleeves are threadedly connected to each of the plurality of studs.
[0007] Preferably, each of the multiple plates is connected to a side plate, each of the multiple discharge ports is connected to two seats, each of the multiple seats is rotatably connected to a corresponding double-ended screw, each of the multiple double-ended screws has a block threadedly connected to one end and the other end, each of the multiple blocks is connected to a stop bar, and each of the multiple stop bars is in contact with a corresponding side plate.
[0008] Preferably, each of the multiple plates is machined with a bevel.
[0009] Preferably, the bottom of the box is designed to be inclined.
[0010] Preferably, rubber pads are adhered to each of the multiple threaded sleeves, and the multiple rubber pads are in contact with the corresponding plate body.
[0011] Preferably, the plurality of seats are respectively connected to the corresponding slide rods, and the plurality of slide rods are respectively slidably connected to the corresponding blocks.
[0012] Preferably, each of the plurality of double-ended screws has a handle connected to one end and the other end.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. Through the coordination between the set box, discharge port, stud and plate, when steel balls are placed in the box, the steel balls will be discharged from multiple discharge ports due to the inclined design of the box. When the steel balls move between the corresponding two plates, the distance between the two plates is gradually widened from the box inlet to the outlet. During the rolling process of the steel balls, when the diameter is smaller than a certain distance, it will fall due to gravity and fall into the corresponding external container. This abandons the "hole-shaped interception" mode of traditional screens and uses two plates to guide the rolling of steel balls. When the steel balls fall, they are only subject to gravity to pass through the distance, without the process of high-speed impact on the screen. It also eliminates the traditional screen replacement process and ensures the production efficiency of steel balls.
[0015] 2. By coordinating the studs, plates, threaded sleeves, double-ended screws, blocks, and stop bars, the distance between the two stop bars is adjusted using the double-ended screws, and the corresponding plates are rotated around the corresponding studs to contact the stop bars. Then, the threaded sleeves are brought into contact with the plates to restrict their movement. This allows for further adjustment of the distance between the two plates, enabling the screening of steel balls of various sizes. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1, referring to Figures 1 to 5 A steel ball screening device for steel ball production and processing includes a housing 1, with multiple discharge ports 2 connected to the housing 1. Each discharge port 2 is connected to two studs 3, and each stud 3 is rotatably connected to a plate 4. Each pair of corresponding plates 4 has a gradually expanding design. Each stud 3 is threadedly connected to a threaded sleeve 5, which cooperates with the studs 3. By rotating the threaded sleeve 5, the angle of the plate 4 can be quickly adjusted, changing the gradually expanding distance between the two plates 4, which facilitates the screening operation of steel balls of different specifications.
[0024] In this embodiment, multiple plates 4 are connected to side plates 11, and multiple discharge ports 2 are connected to two seats 6. Each seat 6 is rotatably connected to a corresponding double-ended screw 7. The two ends of the double-ended screw 7 are respectively forward and reverse threads. Rotating the handle 13 can synchronously drive the two side blocks 8 to move towards or away from each other, adjusting the spacing of the stop rods 9. Each of the multiple double-ended screws 7 has a block 8 threadedly connected to one end and the other end. Each block 8 is connected to a stop rod 9, which contacts the corresponding side plate 11. The stop rod 9 is used to cooperate with the threaded sleeve 5 to adjust and fix the spacing of the side plates 11. Multiple plates 4 are machined with inclined surfaces 10, allowing the steel ball to move between the two plates 4 at an angle. The conveyor is located on the surface 10. The bottom of the box 1 is designed to be inclined. The steel ball is driven by gravity to roll along the inner wall of the box 1 towards the discharge port 2. No additional power device is required, which reduces energy consumption. Rubber pads 12 are attached to multiple threaded sleeves 5. The threaded sleeves 5 are tightened by the external threads of the studs 3, which squeezes the rubber pads 12 to generate friction and fix the angle of the plate 4 to prevent the plate 4 from sliding during the screening process. Multiple rubber pads 12 are in contact with the corresponding plate 4. Multiple seats 6 are connected to the corresponding slide rods 14. Multiple slide rods 14 are slidably connected to the corresponding blocks 8 to ensure that the blocks 8 do not shake when they move horizontally and improve the stability of adjustment. Handles 13 are connected to one end and the other end of multiple double-headed screws 7.
[0025] The working principle of this embodiment is as follows: During use, based on the diameter range of the steel balls to be sorted, the handle 13 is rotated to adjust the distance between the two stoppers 9 by rotating the double-headed screw 7. After adjustment, the plate 4 is rotated around the stud 3, causing the plate 4 to contact the corresponding stopper 9. After contact, the threaded sleeve 5 is rotated at the corresponding stud 3, causing the stud 3 to drive the rubber pad 12 to rotate and connect the plate 4. This allows for further modification of the gradually expanding space between the two plates 4. After modification, the steel balls are continuously fed into the box 1. Due to the tilt of the box 1, the steel balls fall at the discharge port 2 between the corresponding two plates 4. Because the space between the two plates 4 is gradually expanding, the steel balls fall sequentially at the corresponding distances between the two plates 4 according to their diameter during the rolling process. This process does not require screen interception; the steel balls are dynamically graded by size through a purely mechanical structure, avoiding impact wear and jamming problems.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
