Description

Technical Field

[0001] The present application relates to the technical field of steel ball manufacturing, and more specifically to a ball screening mechanism of a steel ball manufacturing device. Background Art

[0002] Steel balls are a common mechanical part, mostly used in fields such as precision bearings. Steel balls play an important role in the precision and reliability of bearings. Steel balls are an indispensable mechanical component in the industrial economy. During the steel ball processing, the probability of mixing steel balls of different sizes is very high. Different industrial fields have different requirements for the specifications and sizes of steel balls. It is often necessary to screen the steel balls to separate steel balls that meet specific specifications and sizes to ensure product quality and performance. By screening the steel balls, the scrap rate caused by steel balls that do not meet the requirements can be reduced in the production process, thereby improving production efficiency and saving production costs. For example, the utility model patent with announcement number CN221620036U discloses a steel ball screening device for a steel ball conveyor, comprising a fixed bracket, a motor is installed on one side of the top wall of the fixed bracket, a driving pulley is installed on the output end of the motor, a belt is sleeved on the surface wall of the driving pulley, an eccentric wheel is sleeved on one side of the inner wall of the belt, a first bracket is installed on one side of the surface wall of the driving pulley, a second bracket is installed on one side of the surface wall of the eccentric wheel, a first connecting shaft is fastened to one side of the surface wall of the eccentric wheel, a connecting wheel is sleeved on one side of the surface wall of the connecting shaft, and a connecting wheel is sleeved on one side of the surface wall of the connecting shaft. A first connecting plate is fastened to one side of the surface wall of the wheel; in this technical solution, the active pulley is driven to rotate by the motor, which in turn drives the first connecting shaft to rotate, and finally drives the three screening nets to move left and right, and the steel balls are screened under the action of the three screening nets with different screening hole sizes. The structure of the steel ball screening device is relatively simple, the error rate in the screening process is high, and the requirements for the size accuracy of the steel balls are low. The steel ball screening device is not applicable to some fields with high requirements for the size of steel balls. Therefore, there is still a need for a screening ball mechanism that can accurately and reliably screen steel balls. Summary of the Invention

[0003] The technical problem to be solved by the present application is to provide a ball screening mechanism for a steel ball manufacturing device, which screens the steel balls by size through the cooperation of a first ball ball collector and a first ball outlet, and the screening is relatively accurate and reliable.

[0004] The present application provides a ball screening mechanism of a steel ball manufacturing device, comprising a hopper and a first ball screening assembly, a first ball-scoring assembly being arranged between the hopper and the first ball screening assembly, the first ball-scoring assembly comprising a first receiving tray and a first ball-scoring device, the hopper being communicated with the first receiving tray, the first receiving tray being provided with a first ball outlet being communicated with the first ball screening assembly, the first ball-scoring device being mounted on the first ball outlet, the first ball-scoring device being provided with a first sieve hole, the steel balls contained in the hopper entering the first receiving tray and entering the first ball screening assembly after being screened through the first sieve hole. In this technical solution, a hopper and a first ball screening assembly are provided, and the steel balls to be screened are piled in the hopper so as to subsequently enter the first ball screening assembly for screening and processing.
