A ball bearing radial clearance measuring method and multi-parameter automatic measuring instrument

Abstract

The invention discloses a ball bearing radial clearance measuring method and a multi-parameter automatic measuring instrument for the inner diameter, the outer diameter and the clearance. The clearance measuring method is an indirect measuring method (the clearance X=D-d-2H), measurement can be carried out before or after a holder is installed, and a ball divider is not needed. The multi-parameter automatic measuring instrument comprises a material plate component, a cam shaft component, a mechanical hand component, a lower support, a measuring head component, a discharging channel component, a material blocking frame component, a mechanical hand stopping component and the like. The inner diameter, the outer diameter and the radial clearance of a bearing can be quickly measured on one station, unqualified products can be automatically sorted in the discharging process, the multi-parameter automatic measuring instrument is especially suitable for detecting semiproducts obtained after balls are installed and before riveting is carried out, the sorted unqualified products can be subjected to nondestructive liner disassembling and repair, loss is reduced, and the qualified rate of products is increased.

Description

Technical field: [0001] This technology relates to automatic detection technology and equipment in the field of bearing manufacturing. Background technique: [0002] The current method of testing the radial clearance of ball bearings in the bearing industry is to fix the inner ring, then apply opposite forces to the outer ring, and measure the displacement of the outer ring at the same time to obtain the radial clearance of the bearing; this method cannot Realize the automatic detection of the radial clearance of the semi-finished bearing without the cage, and it is impossible to quickly detect the three most important parameters of the bearing, the inner diameter, outer diameter and radial clearance of the bearing, at the same station. Invention content: [0003] The patent discloses a method for measuring the radial clearance of a ball bearing and a multi-parameter automatic detector technology for inner diameter, outer diameter and radial clearance. [0004] The differ...
