[0002] Steel balls are a kind of spherical iron alloy wear-resistant body with carbon, chromium, manganese, molybdenum and other metal elements added as the main elements, and produced by forging, spinning, rolling, grinding and casting. Steel balls are the most important component of precision bearings and the most used rolling elements in the bearing industry. In order to arrange the steel balls neatly and reduce unnecessary wear caused by collisions between steel balls, the steel balls coated with anti-rust oil need to be placed in a special steel ball bearing device.

[0003] As retrieved from the existing related patent: CN216735324U, a combined steel ball box is disclosed. The prior art disassembles the shelf and the placement frame to facilitate replacement of the shelf according to the specifications of the steel balls, and there is no need to manufacture multiple steel ball boxes for holding steel balls of different specifications.

[0004] However, the inventor believes that the prior art has the following drawbacks when used: during the steel ball processing process, there is a situation where a small number of steel balls with different diameters need to be carried. Although the prior art can replace shelves of different specifications, shelves of different specifications can only carry steel balls of a single diameter. This results in the need to use multiple carrying devices when carrying steel balls of different diameters, and there is a situation where a single shelf cannot be filled, resulting in vacancies in the placement positions on the shelf, affecting the utilization rate of the carrying device. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a dense bearing steel ball multi-ball bearing device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A multi-ball bearing device for dense bearing steel balls comprises a bearing box, wherein a bearing plate is arranged in the bearing box, a plurality of placement holes arranged in a rectangular array are provided on the bearing plate, two arc-shaped support plates arranged in a mirror image are provided in the placement holes, the two arc-shaped support plates are arranged obliquely and combined into a trumpet shape, a plurality of n-type inner cavities are provided on the bearing plate, the placement holes are located between two transverse grooves of the n-type inner cavity, control rods are arranged on the surfaces of the opposite sides of the two arc-shaped support plates, the other end of the control rod slides through the transverse groove of the n-type inner cavity, and a control component for driving the displacement of the control rod is arranged in the vertical groove of the n-type inner cavity.

DETAILED DESCRIPTION

[0022] See also Figure 1-4 , the utility model provides the following technical solutions:

[0023] Specifically, it refers to a multi-ball bearing device for dense bearing steel balls, including a bearing box 1, a bearing plate 2 is arranged in the bearing box 1, a plurality of placement holes 3 arranged in a rectangular array are opened on the bearing plate 2, two arc-shaped support plates 4 arranged in a mirror image are arranged in the placement holes 3, the two arc-shaped support plates 4 are inclined and combined into a trumpet shape. When in use, a steel ball coated with anti-rust oil is placed between the two arc-shaped support plates 4. Since the two arc-shaped support plates 4 are in the shape of a trumpet, a better supporting effect can be formed on the steel ball, and the problem of the steel ball falling off during the placement process is avoided as much as possible.

[0024] Friction layers 5 are provided on the opposite surfaces of the two arc-shaped support plates 4, which are used to increase the friction between the arc-shaped support plates 4 and the steel balls, thereby avoiding the problem of loosening of the steel balls during placement as much as possible and further ensuring the stability of the steel balls when bearing.

[0025] A plurality of n-type cavities 7 are provided on the bearing plate 2, the number of the n-type cavities 7 is the same as the number of the placement holes 3, and the placement holes 3 are located between the two transverse grooves of the n-type cavity 7. Control rods 6 are provided on the surfaces on the opposite sides of the two arc-shaped support plates 4, and the other ends of the control rods 6 slide through the transverse grooves of the n-type cavity 7. A control component 8 for driving the displacement of the control rods 6 is provided in the vertical grooves of the n-type cavity 7. When in use, the two control rods 6 are driven by the control component 8 to displace in relative or opposite directions, thereby adjusting the distance between the two arc-shaped support plates 4. When carrying steel balls of different diameters, it is only necessary to adjust the distance between the two arc-shaped support plates 4, so that steel balls of various diameters can be placed on the bearing device, further improving the utilization rate of the bearing device.

[0026] The control component 8 includes a screw 82, the upper and lower ends of which are rotatably connected to the upper and lower inner walls of the vertical groove of the n-type inner cavity 7 respectively. A threaded sleeve 86 is provided on the outer surface of the screw 82. The upper end of the screw 82 rotates to pass through the upper surface of the supporting plate 2. A rotating head 81 is provided at the upper end of the screw 82. When in use, the rotating head 81 is rotated, and the rotating head 81 synchronously drives the screw 82 to rotate, so that the threaded sleeve 86 moves upward or downward under the transmission of the threaded teeth of the screw 82.

[0027] The two control rods 6 are both provided with a control plate 83 at one end of the n-type inner cavity 7. One side of the control plate 83 extends into the vertical groove of the n-type inner cavity 7. A rotating plate 84 is hinged between the threaded sleeve 86 and the control plate 83. When the threaded sleeve 86 moves downward, a thrust is applied to the rotating plate 84, so that the rotating plate 84 pushes the control plate 83 to move to the side away from the placement hole 3, so that the distance between the two arc support plates 4 becomes larger. When the threaded sleeve 86 moves upward, a pulling force is applied to the rotating plate 84, so that the rotating plate 84 pulls the control plate 83 to move to the side close to the placement hole 3, so that the distance between the two arc support plates 4 becomes smaller. The above structure can simultaneously control the displacement of the two arc support plates 4, thereby improving the efficiency when carrying steel balls of different diameters.

[0028] A limiting slide bar 85 is provided on the sliding sleeve of the control board 83, and the two ends of the limiting slide bar 85 are arranged on the inner walls on the opposite sides of the horizontal groove of the n-type inner cavity 7. The limiting slide bar 85 is located at the center of the control board 83. In this way, the limiting slide bar 85 forms a limiting effect on the control board 83, and the problem of offset and tilt of the control board 83 is avoided as much as possible.

[0029] An inclined plate 9 is provided on the left inner wall of the carrier box 1, and the inclined plate 9 is located directly below the carrier plate 2. Therefore, when the steel ball coated with anti-rust oil is placed on the carrier plate 2, the anti-rust oil on the surface of the steel ball can drip onto the inclined plate 9, and then slide to the right along the inclined surface of the inclined plate 9. A filter screen 10 for filtering the anti-rust oil is provided between the right side of the inclined plate 9 and the inner wall of the carrier box 1. A drawer 11 that slides into the carrier box 1 is provided on the right side surface of the carrier box 1. The drawer 11 is located directly below the filter screen 10 and slides on the bottom wall of the carrier box 1. Therefore, the anti-rust oil filtered by the filter screen 10 falls into the drawer 11, thereby achieving the purpose of collecting the anti-rust oil and reducing the waste of resources.

[0030] A handle 12 is provided on the right side of the drawer 11 , so the drawer 11 can be pulled out through the handle 12 .

[0031] The working principle of the dense bearing steel ball multi-ball bearing device provided by the utility model is as follows: by rotating the rotating head 81, the rotating head 81 synchronously drives the screw 82 to rotate, so that the threaded sleeve 86 moves upward or downward under the transmission of the threaded teeth of the screw 82, and when the threaded sleeve 86 moves downward, it will apply a thrust to the rotating plate 84, so that the rotating plate 84 pushes the control plate 83 to move to the side away from the placement hole 3, so that the distance between the two arc-shaped support plates 4 becomes larger, and when the threaded sleeve 86 moves upward, it will apply a pulling force to the rotating plate 84, so that the rotating plate 84 pulls the control plate 83 to move to the side close to the placement hole 3, so that the distance between the two arc-shaped support plates 4 becomes smaller.
