Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing equipment technology, specifically to a bearing ball metering device. Background Technology

[0002] In bearing manufacturing, accurate ball metering and conveying are crucial for ensuring assembly quality. Traditional ball supply methods mainly rely on manual sorting or simple funnel-type feeding devices, which suffer from low quantitative accuracy, high risk of clogging, and insufficient flexibility. While existing technologies employ electromechanical control for quantitative control, such as the rotary ball-picking device disclosed in CN218494053U, which achieves single-ball counting through the periodic alignment of the rotating plate's through-hole with the discharge pipe, significant shortcomings remain: they require motors, photoelectric encoders, and complex control systems, resulting in high costs; continuous friction between the rotating plate and the balls can damage the ball surface finish, affecting bearing performance; and the single-ball-per-pass capability is insufficient for batch production cycle requirements. Therefore, there is an urgent need to develop a ball-feeding device with a simple structure, accurate quantitative control, and flexible capacity adjustment to improve conveying efficiency while ensuring zero damage. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bearing ball metering device that can not only flexibly adjust the ball feeding capacity, but also improve the ball conveying efficiency.

Detailed Implementation

[0022] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0023] See Figure 1-6 In one embodiment of this utility model, a bearing ball metering device is provided. The device is used to meter and transport bearing balls and includes: a base 1, a feeding assembly 2, a hopper 3, a bracket 4, a slide 5, a cylinder 6, a first position sensor 7, a second position sensor 8, and a controller (not shown in the figure).

[0024] The hopper 3 is fixed above the base 1 by the bracket 4. The hopper 3 has a box-shaped structure with an inlet 31 for loading the balls 9 at the upper end and an outlet 32 ​​for unloading the balls 9 at the lower end. The opening size of the inlet 31 is larger than the opening size of the outlet 32. At the same time, the opening width of the outlet 32 ​​is adapted to the diameter of the balls 9 to ensure that the balls 9 can flow out of the hopper 3 in an orderly single row.

[0025] The slide table 5 is arranged on the base 1 and below the hopper 3 in a left-right direction; the top of the slide table 5 has an L-shaped groove 51 along its length, and the upper end and front end of the groove 51 are open; the right end of the side wall of the groove 51 has an inclined feed port 52.

[0026] The cylinder 6 is fixedly installed on the base 1, on the left side of the hopper 3, and is used to provide the reciprocating driving force to the feeding assembly 2.

[0027] The feeding assembly 2 is located on the lower side of the hopper 3 via a cylinder 6. The feeding assembly 2 includes a feeding plate 21, a fixing plate 22, and a capacity adjustment assembly 23. The left end of the feeding plate 21 is fixedly connected to the output end of the cylinder 6 via the fixing plate 22. A guide groove 211 is provided at the right end of the feeding plate 21. The front and rear ends of the guide groove 211 are open, and the opening direction of the guide groove 211 is perpendicular to the length direction of the slide table 5. Furthermore, the bottom wall of the guide groove 211 is designed to be inclined with the front higher than the back. In implementation, the inclination angle of the bottom wall of the guide groove 211 is usually 10°~15°, so that the ball 9 can slide towards the slide table 5 by its own weight. The width of the guide groove 211 is adapted to the diameter of the ball 9, and the guide groove 211 can allow multiple balls 9 to be arranged in a single straight line within it.

[0028] The rear end of the feed plate 21 is slidably mounted on the slide table 5. Specifically, the rear end of the feed plate 21 is slidably connected to the side wall of the slide groove 51. This arrangement allows the slide table 5 to dynamically close the rear end of the guide groove 211. The lower end of the feed plate 21 is in slidable contact with the bottom wall of the slide groove 51. The feed port 52 is located within the sliding stroke of the guide groove 211.

[0029] The upper end of the feeding plate 21 is slidably connected to the lower end of the hopper 3. During the process of the cylinder 6 driving the feeding plate 21 to repeatedly move below the hopper 3, the upper surface of the feeding plate 21 dynamically blocks or opens the outlet 32 ​​of the hopper. When the outlet 32 ​​coincides with the guide groove 211, the balls 9 flow from the hopper into the guide groove 211 until it fills its effective loading section. It can be seen that the effective length of the guide groove 211 determines the number of balls 9 loaded in a single loading. In this embodiment, the size of the outlet 32 ​​is smaller than the size of the guide groove 211.

[0030] The capacity adjustment component 23 is movably installed on the right end of the feed plate 21 and corresponds to the position of the guide groove 211. It is used to block the front end of the guide groove 211. At the same time, by adjusting the position of the capacity adjustment component 23, the effective loading length of the guide groove 211 is changed, thereby precisely controlling the number of balls 9 loaded in a single load. The capacity adjustment component 23 includes a slider 231, a push button 232 and a connecting plate 233. The slider 231 and the push button 232 are fixedly connected by the connecting plate 233. The push button 232 is provided with an anti-slip groove.

[0031] The right end of the feed plate 21 is provided with a connecting hole 212 that communicates with and is perpendicular to the guide groove 211. The size of the connecting hole 212 is larger than the size of the connecting plate 233, allowing the connecting plate 233 to slide back and forth within the connecting hole 212.

[0032] The connecting plate 233 passes through the connecting hole 212. The slider 231 is slidably disposed in the guide groove 211 as the front end baffle of the guide groove 211, and the upper end of the slider 231 is flush with the upper end of the feeding plate 21. The push button 232 is disposed on the right side of the feeding plate 21. By manually sliding the push button 232 back and forth, the slider 231 is driven to move back and forth in the guide groove 211, thereby adjusting the effective loading length of the guide groove 211.

[0033] The cylinder 6, the first position sensor 7, and the second position sensor 8 are all connected to the controller via circuits; the first position sensor 7 and the second position sensor 8 are both located on the base 1 and below the hopper 3, and the first position sensor 7 and the second position sensor 8 are arranged at intervals along the sliding direction of the feed plate 21, wherein the first position sensor 7 is close to the feed plate 21.

[0034] Working principle:

[0035] In the initial position, the guide groove 211 is located on the left side of the hopper 3. The controller controls the cylinder 6 to start and push the feed plate 21 to slide to the right. When the feed plate 21 moves to trigger the first position sensor 7, the controller controls the cylinder 6 to pause for 5 to 10 seconds. At this time, the outlet 32 ​​coincides with the position of the guide groove 211, and the ball bearing 9 flows from the hopper 3 into the guide groove 211 until it is filled to its currently set effective loading length.

[0036] After the pause ends, the controller instructs the cylinder 6 to continue pushing the feed plate 21 to slide to the right. When the feed plate 21 moves to trigger the second position sensor 8, the controller pauses the cylinder 6 again for 5 to 10 seconds. At this time, the outlet (rear end) of the guide groove 211 corresponds to the position of the feed port 52. Under the action of its inclined bottom wall, the ball 9 in the guide groove 211 slides out through the rear end of the guide groove 211 by its own weight and flows orderly to the next production process through the feed port 52 of the slide table 5.

[0037] In one embodiment, to further simplify the structure of the device, the capacity adjustment component 23 can be a pin, which can be movably disposed in the guide groove 211, and can also close the front end of the guide groove 211.

[0038] This technical solution precisely controls the effective loading length of the guide groove through a sliding adjustable capacity adjustment component, achieving stepless adjustment of the number of balls output per cycle and significantly improving quantitative accuracy. The inclined guide groove design allows the balls to slide entirely by their own weight, completely eliminating surface damage caused by mechanical friction. Based on a reciprocating motion mechanism driven by a cylinder and coordinated with a position sensor, multiple balls can be output in a single operation, significantly improving efficiency compared to traditional single-ball counting schemes. Furthermore, compared to existing technologies, the overall structure of this device eliminates complex electrical control units such as motors and encoders, greatly reducing manufacturing costs and maintenance difficulty. The dynamic enclosed design of the slide table also prevents ball jamming, ensuring stability during continuous operation.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
