An auxiliary structure for bearing processing and assembly

Abstract

The present invention discloses an auxiliary structure for bearing processing and assembly, which relates to the technical field of bearing assembly, and includes a support seat. An equidistant connecting member is arranged on the U-shaped frame plate, and a sequential movement unit is arranged at the top of the positioning column. By setting the equidistant connecting member, the telescopic cylinder extends to rotate the transmission coupling shaft by 180 degrees. During this process, the support connecting frame first moves upward, and then the second movable arc-shaped block and multiple first movable arc-shaped blocks move to directly below the multi-connection pipe. When the steel balls fall from the multi-connection pipe, the steel balls will fall to the inside of the groove. When the telescopic cylinder contracts, first, the steel balls are evenly distributed around the inner ring of the bearing as the second movable arc-shaped block rotates, and then the positioning arc-shaped block moves to below the outer ring placement rack, so as to achieve the effect of evenly distributing the steel balls. When installing the cage between the outer ring and the inner ring of the bearing, the card slot therein can be quickly buckled on the outside of the steel balls, thereby improving the assembly efficiency of the bearing.
