Roller roundness detection device

Abstract

The invention discloses a roller roundness detection device, which comprises an inductance meter and a roller clamping device, wherein the roller clamping device comprises a base, a magnetic positioning component and an elastic pressing component; the base comprises a first fixing surface extending in a horizontal direction; the magnetic positioning component comprises a second fixing surface withmagnetic attraction; the second fixing surface extends in a vertical direction and is adjacent to the first fixing surface; a measuring head of the inductance meter is in contact with the top surfaceof a first pressing plate of a leaf spring; and the arc surface of the elastic pressing component is in contact with a ball point to be measured. According to the roller roundness detection device, the measuring head of the inductance meter does not need to be in direct contact with the cylindrical surface of a roller, the trouble of finding the highest point of the cylindrical surface of the roller is omitted, the abrasion of the measuring head of the inductance meter is reduced, and meanwhile, the requirements for the technical level of an operator are reduced, the detection device is simple, the detection efficiency is improved, and the device has the advantages of low cost and high efficiency.

Description

technical field [0001] The invention relates to a roller detection device, in particular to a roller roundness detection device. Background technique [0002] The roller is a cylindrical body with a large length-to-diameter ratio, no side plate structure, and can be rotated. It is one of the important components of mechanical parts such as roller bearings and roller guides. It must be Check this roundness indicator. [0003] To detect the roundness of the roller, it is necessary to measure the maximum and minimum values ​​of the actual contour in the diameter direction in any section. The commonly used measuring tools include vernier calipers, micrometers, three coordinates, universal tool microscopes and inductance meters. The measurement accuracy of vernier calipers is relatively high. Low, the measurement accuracy of micrometer and three-coordinate measuring machine is slightly better, but it is difficult to reach below the micron level; the measurement accuracy of unive...

[0003] To detect the roundness of the roller, it is necessary to measure the maximum and minimum values ​​of the actual contour in the diameter direction in any section. The commonly used measuring tools include vernier calipers, micrometers, three coordinates, universal tool microscopes and inductance meters. The measurement accuracy of vernier calipers is relatively high. Low, the measurement accuracy of micrometers and three-coordinate measuring machines is slightly better, but it is difficult to reach below the micron level; the measurement accuracy of universal tool microscopes is greatly affected by the operator's viewing and aiming errors and subjective judgments when reading, and the efficiency is relatively low; inductance The measurement accuracy of the instrument can reach the sub-micron level, but it is necessary to ensure that the measuring head of the inductance meter is in contact with the highest point of the cylindrical surface of the roller to be tested, and the roller must be rotated continuously, so the wear of the measuring head of the inductance meter is relatively large. Large, secondly, the technical level of the operator is relatively high
