[0030] Combined with Figures 1 to 6 As shown, a bearing steel ball production and processing device provided by the present utility model includes a track 1 and a sliding plate 2.
[0031] Combined with Figures 1 to 6 As shown, the track 1 is inclined, and the steel balls roll from top to bottom through the track 1 under the action of gravity. The track 1 includes at least two acceleration sections 11 with different directions. The acceleration sections 11 are connected in series in sequence, and the lengths of the acceleration sections 11 with different directions are equal. The sliding plate 2 is horizontally arranged and connected to the lower outlet of the track 1. The steel balls roll on the sliding plate 2, and the rolling distance of the steel balls reflects their own roundness.
[0032] In this embodiment, the rotation of the steel balls is accelerated by the track 1, and the overall roundness of the steel balls is judged by the rolling distance of the steel balls on the sliding plate 2. Among them, the track 1 realizes the rotational acceleration of the steel balls in multiple directions through the acceleration sections 11 with different directions. The rotational acceleration in multiple directions is affected by the roundness of the steel balls in multiple directions, and the final rotational speed of the steel balls will also affect their rolling distance on the sliding plate 2, realizing the detection of the overall roundness of the steel balls with low cost and low difficulty.
[0033] In some embodiments, combined with Figure 5 As shown, the track 1 is composed of two parallel contact strips. The distance between the two contact strips is less than the diameter of the steel balls. The two contact strips jointly support the steel balls in the form of point contact. Using this kind of track 1 to support the steel balls can realize the control of the trajectory of the steel balls without designing baffles, reduce the influence of the track 1 itself on the rotation of the steel balls, and at the same time, the point contact support form can avoid the sliding of the steel balls during the rolling process on the track 1.
[0034] In some embodiments, combined with Figure 2 、 Figure 3As shown, the track 1 further includes a docking section 12. The acceleration section 11 is a straight track, and the docking section 12 is an arc-shaped track. The docking section 12 is connected in series between adjacent acceleration sections 11 for transition, and the docking section 12 is also connected in series between the acceleration section 11 and the sliding plate 2 for transition. The docking section 12 makes the rolling process of the steel ball smoother by virtue of its arc-shaped feature, avoiding a large loss of rotational kinetic energy during the process of direction conversion.
[0035] In some embodiments, in combination with Figure 4 As shown, the track 1 includes a serpentine track 13. The serpentine track 13 replaces the acceleration section 11 and is connected to the sliding plate 2 through the docking section 12. The serpentine track 13 itself consists of segments in multiple directions and is overall smooth. Compared with the track 1 composed of the acceleration section 11 and the docking section 12, the serpentine track 13 gives a visual sense of a circle compared to a polygon.
[0036] In some embodiments, in combination with Figure 5 As shown, a deceleration layer is laid on the sliding plate 2. Designing the deceleration layer can reduce the sliding distance of the steel ball on the sliding plate 2 in a certain proportion, reduce the requirement for the length of the sliding plate 2, and reduce the volume of the equipment.
[0037] In some embodiments, in combination with Figure 2 As shown, the inclination angle of the track 1 is between 5 degrees and 20 degrees. The inclination angle of the track 1 is an important factor affecting the acceleration process of the steel ball. However, theoretically, the smaller the inclination angle of the track 1, the greater the influence of the roundness of the steel ball itself on the acceleration process. But if the inclination angle of the track 1 is too small, it will cause the rolling distance of the steel ball to be too small to produce a distinguishable effect.
[0038] In some embodiments, in combination with Figure 1 As shown, the sliding plate 2 is connected to a plurality of tracks 1 arranged side by side. It is best to measure only a single steel ball on each track 1 each time. Increasing the number of tracks 1 can directly increase the measurement efficiency. Steel balls with lower speeds cannot affect the movement of steel balls with higher speeds. Therefore, the tracks 1 arranged side by side will not affect each other's detection results.
[0039] In some embodiments, in combination with Figure 1 、 Figure 6As shown, the bearing steel ball production and processing equipment further includes a collection device 3. The collection device 3 includes a scraper 31. The scraper 31 is located above the sliding plate 2, and the lower end of the scraper 31 slides and abuts against the sliding plate 2. The top end of the scraper 31 is slidably assembled on the slide rail. The scraper 31 reciprocates along the slide rail. The slide rail is arranged perpendicular to the sliding direction of the steel balls. The collection device 3 is responsible for classifying and collecting the inspected steel balls. The scraper 31 can scrape the steel balls to a predetermined position, clearing the area above the sliding plate 2 for the next inspection.
[0040] In some embodiments, in combination with Figure 6 As shown, a partition baffle 32 is integrally formed and vertically provided on the scraper 31. The number of the partition baffles 32 is 2. The partition baffles 32 are located at both ends of the scraper 31. Since the rolling performance of the steel balls themselves is relatively good, there is a risk that the steel balls will be mixed again and the steel balls will return to the track 1 during the scraping process. The partition baffle 32 can effectively reduce the above risks.
[0041] In some embodiments, in combination with Figure 6 As shown, the collection device 3 further includes a first collection basket 33 and a second collection basket 34. The first collection basket 33 and the second collection basket 34 are sequentially arranged below the sliding plate 2 along the rolling and sliding direction of the steel balls on the sliding plate 2. The scraper 31, the sliding plate 2, and the first collection basket 33 are vertically distributed from top to bottom. The edge of the second collection basket 34 is butted against the edge of the sliding plate 2. The scraper 31 continuously sends the steel balls into the first collection basket 33 through reciprocating motion. The steel balls with higher roundness will directly fall into the second collection basket 34 due to sufficient sliding distance, and the steel balls with insufficient sliding distance will be collected into the first collection basket 33 under the action of the scraper 31, realizing classified collection.
[0042] Working process: After the steel balls enter the track 1, the steel balls will sequentially pass through the acceleration sections 11 with different directions; during this process, the steel balls will convert gravitational potential energy into rotational kinetic energy. The efficiency of the steel balls converting kinetic energy will be affected by their roundness in this direction. The worse the overall roundness of the steel balls, the less kinetic energy will be finally converted.
[0043] Subsequently, the steel balls enter the sliding plate 2. The steel balls roll and slide on the sliding plate 2. The kinetic energy converted by the steel balls will be directly reflected in their sliding distance on the sliding plate 2.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
