Description

Technical Field

[0001] The utility model relates to the technical field of steel ball production and processing, in particular to a steel ball rolling bar sorting mechanism. Background Art

[0002] Steel balls are important basic parts in bearings, especially precision industrial steel balls, which play a huge role in the development of the national economy. Steel balls need to be polished and ground. When the steel balls are turned over for polishing, in order to achieve the best polishing effect, steel balls of different sizes need to be mixed and polished together. After polishing, the steel balls need to be sorted. The existing steel balls are generally sorted by size through two pairs of rollers, that is, two parallel rods. The gap between the two gradually expands from one end to the other. Steel balls of different sizes can fall into different receiving boxes below them during the movement for screening. Although it has wide applicability and high sorting efficiency, it also has some shortcomings, that is, the two sets of rods in the traditional sorting mechanism are usually in an "eight" shape. Since the steel balls are of different sizes and in large numbers during the sorting process, it is inevitable that there will be certain friction and extrusion between the steel balls, and the larger steel balls will have a smaller volume than the smaller ones. The steel balls have a faster frequency and a larger movement amplitude during the rolling process, so that the relatively small steel balls are easily stuck between the two rods due to the squeezing of the relatively large steel balls during the sorting process, which causes the steel balls to fall into the inappropriate receiving box ahead of time or delayed, and mix with the steel balls of different sizes. When this phenomenon occurs, the traditional steel ball sorting mechanism often directly carries out subsequent packaging or installation processes for the batches of steel balls in multiple receiving boxes after the sorting is completed. The steel balls of different sizes mixed in the receiving boxes cannot be removed or separated, and if the batches of steel balls that have been finely ground, polished, and before and after sorting have deformation problems, it is not convenient to carry out further screening, which can easily affect the quality of the subsequent packaging and the installation effect.

After screening by the screening component 5, the steel balls stored in different cavities of the receiving box 4 can be convenient for the operator to carry out subsequent processing. In addition, the screening component 5 with such a structural arrangement can be selected and adjusted according to specific usage requirements, and the size of the sieve holes 521 on the sieve plate 52 can be selected and adjusted according to the specific size of the steel balls to be sorted and the specific position of the feed hopper 3 below the conveying track 2, so that the volume of the steel balls in the first channel 511 and the second channel 512 changes with the change of the sieve holes 521 on the sieve plate 52, and is not limited to the above-mentioned embodiment, thereby ensuring the stability and accuracy of batch steel balls during the screening process.
