Embodiment Construction

[0030] The invention is a method for measuring the radius of curvature of a cylindrical roller. The invention uses a laser displacement sensor to measure the curvature radii of two different arcs at the same height of a cylindrical roller, and then uses the least square method to fit the radius of curvature at the height. The radius of curvature, repeating the same process can measure the radius of curvature at other heights, thereby calculating the total radius of curvature of the cylindrical roller, and judging whether the total radius of curvature meets the design requirements.

[0031] combine figure 1 , The method of the present invention uses a set of measuring devices, the measuring device includes a base 1, a two-dimensional mobile movable frame 2, a bracket 3, a laser displacement sensor 4, a clamping sleeve 6, an air bearing turntable 7, and an air bearing 8 And the servo motor 9, the rotation angle and the rotation speed v of the servo motor 9 1 and v 2 are contro...

Abstract

The invention discloses a method for measuring the curvature radius of a cylindrical roller, and the method employs a measurement device. The measurement device comprises a substrate, a two-dimensional moveable frame, a support, a laser displacement sensor, a clamping sleeve, an air-bearing turntable, an air bearing, and a servo motor. The method employs the laser displacement sensor to measure the curvature radiuses of two arcs of the cylindrical roller at the same height. The method employs a non-contact mode, so the method cannot damage the precise structure and contour of the surface arc of the cylindrical roller in a measurement process. The method carries out the fitting of the curvature radius at the height through a least square method. The method can measure the curvature radius at other heights through the same operation process, thereby calculating the total curvature radius of the cylindrical roller, judging whether the total curvature radius meets the design requirements or not, improving the measurement precision of the curvature radius of the cylindrical roller, avoiding a manual error, and effectively improving the performance of the cylindrical roller overall when the cylindrical roller leaves a factory. The method is simple and reliable, and the measurement device can be used repeatedly.

Description

technical field [0001] The invention belongs to the technical field of automatic detection of bearing rollers, and in particular relates to a method for measuring the radius of curvature of cylindrical rollers. Background technique [0002] The radius of curvature of a cylindrical roller reflects the characteristic quality of its surface geometry, which not only affects the assembly quality of the bearing, but also determines the stability of the bearing. However, limited by the level of processing, there are often small differences in the radius of curvature of the finished cylindrical rollers, which are the key to restricting the improvement of bearing performance. Therefore, after grinding, it is necessary to check whether the curvature radius of the cylindrical roller meets the precision and design requirements. [0003] In actual testing, the measurement methods for the curvature radius of cylindrical rollers mainly include profiling method, standard roller coloring me...
