Problems solved by technology
[0002] A large number of steel balls are used in the bearings. During the screening process of steel balls, large and small steel balls are easy to mix together, which is very troublesome in the screening process. Due to the different diameters of the existing screening machines and the screening plates cannot be replaced, there are problems in the screening process. The shortcomings of high labor intensity, low efficiency and poor screening effect cannot meet the actual needs of production

The invention discloses a screening gate plate of a steel ball screening machine. A carrying frame is arranged on the lower portion of the inner wall of a screening box, the screening grate plate is connected to the carrying frame in a clamping mode and comprises an upper screening plate, a lower screening plate, a connecting shaft and clamping buckles, wherein the center of the upper screening plate and the center of the lower screening plate are connected through the connecting shaft, the upper screening plate and the lower screening plate are round, the upper screening plate is provided with round holes, the lower screening plate is provided with rectangular holes, the width of the rectangular holes is the same as the diameter of the round holes, and the length of the rectangular holes is larger than the diameter of the round holes. Two clamping grooves are formed in the inner side of each clamping buckle, a clamping edge extends from the outer side of each clamping buckle, the edge of the outer side of the upper screening plate and the edge of the outer side of the lower screening plate are connected in the clamping grooves of the clamping buckles respectively, the upper screening plate and the lower screening plate are made of nodular cast iron, and the number of the clamping buckles is at least three. The screening gate plate of the steel ball screening machine has the advantages of being simple in structure and good in screening effect.
Description
technical field [0001] The invention belongs to the technical field of screening equipment, and in particular relates to a screening grate of a steel ball screening machine. Background technique [0002] A large number of steel balls are used in the bearings. During the screening process of steel balls, large and small steel balls are easy to mix together, which is very troublesome in the screening process. Due to the different diameters of the existing screening machines and the screening plate cannot be replaced, there are problems in the screening process. The shortcomings of high labor intensity, low efficiency and poor screening effect cannot meet the actual needs of production. Contents of the invention [0003] The invention aims to overcome the defects of the prior art, and provides a screening grate plate of a steel ball screening machine, which has the advantages of simple structure and good screening effect. [0004] In order to solve the problems of the techno...
