Bearing section thickness measuring device

Abstract

The invention relates to a bearing section thickness measuring device. The device comprises a base, a supporting seat, a measuring rod and a measuring mechanism, wherein the supporting seat is connected with the base through a first sliding mechanism, and a positioning stop block installed on the supporting seat limits the measurement position of the bearing. The measuring rod is connected with the base through a second sliding mechanism and is arranged at one side of the supporting seat; the measuring rod is fixed on a sliding block through a fine adjustment mechanism to realize measurement; the measuring mechanism comprises a fixed measuring point, a floating measuring point and a measuring meter and is connected with the measuring rod.

Description

Technical field [0001] The invention relates to a bearing measuring device, in particular to a bearing section thickness measuring device. Background technique [0002] In the bearing industry, some bearings need to control the section thickness of the bearing. The existing measurement method is to fix the inner ring, rotate the outer ring, and measure the point at the outer ring. [0003] The existing measuring method with fixed inner ring, rotating outer ring, and measuring point on the outer ring, the inner ring is fixed, the inner diameter of the fixed measuring point is fixed at the same time, the dynamic measuring point is at the outer diameter, and the outer ring is rotated to obtain the measured value. [0004] Due to the large size difference between the inner diameter and outer diameter of the bearing, the outer ring has a large wall thickness and weight, the inner diameter of the bearing cannot be positioned stably, resulting in a large measurement error; the dynamic measu...

AI Technical Summary

Problems solved by technology

[0004] Due to the large size difference between the inner diameter and outer diameter of the bearing, the wall thickness of the outer ring is large and the weight is large, the inner diameter of the bearing cannot be positioned stably, resulting in large measurement errors; the dynamic measurement point is on the rotating surface, resulting in wear of the measurement point , affecting the measurement accuracy

[0005] Since the inner diameter of the bearing is concave, the fixed measuring points cannot be made into a plane, and conventional standard parts cannot be used to determine the size reference. The measured value is the difference between the cross-sectional thickness of each single bearing, and an accurate value cannot be measured

[0006] When measuring, if a single-point support is used, the measurement error will be large due to insufficient rigidity of the support point; if a double-point support is used, it will cause difficulties in installation and fixing during measurement, which will affect the measurement efficiency
