Deformation analyzer of barrel body

Abstract

A cylindrical deformation measurement device, comprising: a fixed linear guide rail part 3 arranged on a flat surface 2, a cylindrical body transfer mechanism part 4, a reference column part 5, a laser scanning micrometer 6, and a control part 7 The cylindrical body transfer mechanism part 4 rotates the cylindrical body C in a state where the peripheral surface of one end side is in contact with the fixed linear guide rail part 3; the reference column part 5 is perpendicular to the rotational direction Fc of the cylindrical body C The laser scanning micrometer 6 scans the upper part of the cylinder C and the reference column part 5 simultaneously by the laser light L projected toward the rotation direction Fc, and measures the cylinder C. The interval W between C and the reference column portion 5; the control portion 7 measures the data to obtain the amount of deformation Ed. In this way, reproducible and highly accurate measurements can be performed, and at the same time, full automation can be easily performed, and more stable and reliable measurements can be performed.

Description

technical field [0001] The present invention relates to a deformation amount measuring device of a cylindrical body suitable for use when measuring the radial deformation strain amount of a cylindrical body such as an inner ring and an outer ring of a bearing. Background technique [0002] Generally, when there is deformation in the radial direction of the inner ring Ci and the outer ring Co of the ball bearing M as shown in FIG. Vibration in the axial direction and the like cannot provide smooth and stable rotational performance. Therefore, it is required to reduce the deformation of the inner ring Ci and outer ring Co as much as possible. That is, when the position where the lower end surface Cid of the inner ring Ci is fixed is rotated once, the radial deformation amount Ed of the upper end surface Ciu of the inner ring Ci is ideally zero, but in reality there is deformation, and it is required to make the deformation The quantity Ed is within specified tolerances.

AI Technical Summary

Problems solved by technology

[0005] First, with mechanical contact, especially in cylindrical bodies C such as small inner rings Ci with an outer diameter of several mm or less, measurement errors become large, and reproducible, high-precision measurements cannot be performed.

[0006] Second, since the main work has to be done manually by the operator, the measurement is time-consuming and troublesome, and it cannot be measured with high stability and reliability.
