Description

Technical Field

[0001] This utility model relates to the field of bearing steel ball size detection technology, and in particular to a high-precision size detection device for bearing steel balls. Background Technology

[0002] As a key component of precision machinery, the dimensional accuracy of bearing steel balls directly affects the operating performance and service life of bearings. Currently, the dimensional inspection of bearing steel balls mainly relies on manual screening or traditional screening equipment. These methods have problems such as low efficiency and unstable accuracy. In particular, for the dimensional stratification screening of large batches of steel balls, traditional methods are difficult to achieve fast and accurate classification, resulting in great difficulty in quality control during the production process and failing to meet the needs of high-precision bearing manufacturing.

[0003] Existing steel ball size detection devices mostly use a single screen or a fixed aperture screening structure, which cannot efficiently screen steel balls of different size ranges at the same time. In addition, the traditional manual screening method is prone to jamming or missed detection of steel balls during the screening process, resulting in low efficiency and further reducing the detection efficiency and accuracy. To address the above problems, we have launched a high-precision size detection device for bearing steel balls. Utility Model Content

[0004] This utility model discloses a high-precision dimension detection device for bearing steel balls, which aims to solve the technical problem of bearing steel ball dimension detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Three inspection frames are equidistantly arranged inside the support frame. The bottom of the inner walls of the three inspection frames are arranged in a rectangular array with holes for dimensional inspection. The diameter of the holes in the three inspection frames decreases sequentially from top to bottom. An inspection mechanism is provided inside the support frame. The inspection mechanism includes an inspection component, a power component, and a feeding component. The inspection component, power component, and feeding component work together. The inspection component includes a limiting slide groove located on the outer side of the support plate. Sliding rods are fixedly connected equidistantly on both sides of the support frame. Sliding blocks are slidably connected to the outer side of each sliding rod. The sliding blocks and the limiting slide groove are slidably connected. A return spring is sleeved on the outer side of each sliding rod.

[0007] The set-up detection mechanism can accurately classify steel balls of different sizes. Compared with manual sieving, it saves labor costs. Compared with single-mesh sieving, it greatly improves sieving efficiency. It can quickly distinguish steel balls of different diameters. The structure is simple and highly practical.

[0008] In a preferred embodiment, the power assembly includes a motor, which is fixedly connected to the outer side of the support frame.

[0010] In a preferred embodiment, the feeding assembly includes a feeding hopper, which is fixedly connected to the top of the support frame, and the inside of the feeding hopper is fixedly connected with distribution plates at equal intervals.

[0011] The feed hopper and distribution plate in the feeding assembly can evenly distribute the steel balls, avoiding accumulation or jamming, ensuring that the steel balls enter the detection frame in an orderly manner, and improving the continuity and stability of the detection.

[0012] In a preferred embodiment, a collection box is placed on the side of the support frame away from the motor.

[0013] A collection box is provided on one side of the support frame to facilitate the collection of larger, non-compliant steel balls, thereby improving the sorting efficiency and reducing the workload of manual sorting.

[0014] In a preferred embodiment, a protective cover is fixedly connected to the outside of the motor for protection, and heat dissipation slots for the motor to dissipate heat are equidistantly opened inside the protective cover.

[0015] The motor is equipped with a protective cover and heat dissipation slots on the outside, which can protect the motor from the influence of the external environment, effectively dissipate heat, extend the service life of the motor, and improve the reliability of the equipment.

[0016] In a preferred embodiment, a controller is fixedly connected to the outside of the support frame, and the motor is electrically connected to the controller.

[0017] A controller is installed on the outside of the support frame, which can precisely control the speed and vibration frequency of the motor, optimize the detection process, improve the degree of automation, and make the operation more convenient.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] The high-precision dimension detection device for bearing steel balls disclosed in this utility model is mainly used in the scenario of detecting the dimension of bearing steel balls.

[0029] Reference Figure 1 - Figure 5 A high-precision dimension detection device for bearing steel balls includes a support frame 1. Support plates 2 are equidistantly arranged on both sides of the support frame 1. Three detection frames 3 are equidistantly arranged inside the support frame 1. The bottom of the inner walls of the three detection frames 3 are arranged in a rectangular array with holes for dimension detection. The diameter of the holes in the three detection frames 3 decreases sequentially from top to bottom. A detection mechanism is provided inside the support frame 1. The detection mechanism includes a detection component, a power component, and a feeding component. The detection component, power component, and feeding component work together. The detection component includes a limiting slide groove 41, which is located on the outer side of the support plate 2. Slide rods 42 are fixedly connected equidistantly on both sides of the support frame 1. Slide blocks 43 are slidably connected to the outer side of the slide rods 42. The slide blocks 43 and the limiting slide groove 41 are slidably connected. A return spring 44 is sleeved on the outer side of the slide rods 42. The power assembly includes a motor 45, which is fixedly connected to the outer side of the support frame 1. A rotating shaft 47 is rotatably connected to the side of the support frame 1 near the motor 45. One end of the rotating shaft 47 is fixedly connected to the output end of the motor 45. A cam 48 is symmetrically fixedly connected to the outer side of the rotating shaft 47. Three detection frames 3 are symmetrically fixedly connected to limit rails 46 on the side near the motor 45. The limit rails 46 and the cams 48 are slidably connected.

[0030] In this embodiment: Steel balls first enter from the feed hopper 5, are evenly dispersed by the distribution plate 6, and fall into the uppermost detection frame 3. At this time, the motor 45 starts, driving the cam 48 to rotate via the rotating shaft 47, causing the detection frame 3 to vibrate regularly with the help of the limiting track 46. During the vibration, steel balls smaller than the aperture of the upper detection frame 3 fall into the middle detection frame 3, while the remaining steel balls continue to roll and be screened within the upper detection frame 3. Similarly, the vibration of the middle detection frame 3 causes steel balls that meet its aperture requirements to fall into the lower detection frame 3, and the smallest steel ball eventually passes through the hole in the lower detection frame 3. Throughout the process, the reset spring 44 ensures that the detection frame 3 can quickly reset after vibration, while the cooperation of the sliding block 43 and the sliding rod 42 ensures the stability of vibration. Through the set detection mechanism, steel balls of different sizes can be accurately graded. Compared with manual screening, it saves labor costs. Compared with single screen screening, it greatly improves screening efficiency. It can quickly distinguish steel balls of different diameters. The structure is simple and highly practical.

[0031] In the above technical solution, considering the issue of bearing steel ball size detection, the specific operation is as follows to solve this problem:

[0032] Reference Figure 1 - Figure 5 In a preferred embodiment, the feeding assembly includes a feeding hopper 5, which is fixedly connected to the top of the support frame 1. Distributor plates 6 are fixedly connected at equal intervals inside the feeding hopper 5. A collection box 7 is placed on the side of the support frame 1 away from the motor 45. A protective cover is fixedly connected to the outside of the motor 45, and heat dissipation slots for cooling the motor 45 are evenly spaced inside the protective cover. A controller 8 is fixedly connected to the outside of the support frame 1, and the motor 45 is electrically connected to the controller 8.

[0033] In this embodiment, the feeding hopper 5 and the distribution plate 6 in the feeding assembly can evenly distribute the steel balls, avoiding accumulation or jamming, ensuring that the steel balls enter the detection frame 3 in an orderly manner, and improving the continuity and stability of the detection. A collection box 7 is provided on one side of the support frame 1 to facilitate the collection of larger, non-conforming steel balls, improving the sorting efficiency and reducing the workload of manual sorting. A protective cover and heat dissipation grooves are provided on the outside of the motor 45, which can protect the motor 45 from external environmental influences and effectively dissipate heat, extending the service life of the motor 45 and improving the reliability of the equipment. A controller 8 is provided on the outside of the support frame 1, which can precisely control the speed and vibration frequency of the motor 45, optimizing the detection process, improving the degree of automation, and making operation more convenient.

[0034] Working Principle: Steel balls first enter from the feed hopper 5, are evenly dispersed by the distribution plate 6, and fall into the uppermost detection frame 3. At this time, the motor 45 starts, driving the cam 48 to rotate via the rotating shaft 47. With the cooperation of the limiting track 46, the detection frame 3 vibrates regularly. During vibration, steel balls smaller than the aperture of the upper detection frame 3 fall into the middle detection frame 3, while the remaining steel balls continue to roll and be screened within the upper detection frame 3. Similarly, the vibration of the middle detection frame 3 causes steel balls meeting its aperture requirements to fall into the lower detection frame 3, with the smallest steel ball ultimately passing through the holes in the lower detection frame 3. Throughout the process, the return spring 44 ensures that the detection frame 3 can quickly return to its original position after vibration, while the cooperation of the sliding block 43 and the sliding rod 42 ensures the stability of the vibration. Finally, steel balls of different sizes are accurately graded. The steel balls in the uppermost detection frame 3 are the larger, unqualified steel balls, and after screening, they are swept into the collection box 7, completing the entire process of automated, high-precision size detection. The controller 8 can adjust the speed of the motor 45 in real time to optimize the vibration frequency and ensure the best screening effect.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
