Problems solved by technology

[0004] 1. The measuring head of the torsion spring comparator needs to apply a certain pressure to be in contact with the measured surface (or line, point) to perform the measurement. The applied pressure is called the measuring force, and the measuring force can be as high as 1-3N. Thin-walled bearing sleeves Under the action of the measurement force, the rings are squeezed against each other, which will cause contact deformation errors of the thin-walled bearing rings, resulting in force measurement errors
[0005] 2. When the existing caliper is positioned on the thin-walled bearing ring, it uses an inclined track to adjust the positioning rod. When adjusting, it is easy to cause upward or downward, resulting in the point that the outer wall of the outermost side of the bearing ring cannot be pointed. , so that the measuring head of the torsion spring comparator does not point to the center of the bearing ring, resulting in eccentricity error

Abstract

The invention discloses a device and method for measuring the outer diameter of a thin-walled bearing ring. The device includes a support frame, a workbench arranged on the support frame, a positioning mechanism, a measurement mechanism and a counter-arriving mechanism arranged on the workbench; A measuring center is set on the workbench, and the positioning mechanism includes a Y-axis positioning mechanism and an X-axis positioning mechanism arranged on the workbench; the measuring mechanism includes a torsion spring comparator slidingly arranged on the workbench and a The spring comparator moves along the Y-axis direction on the working table; Anti-resistance adjustment mechanism for the anti-resistance rod to move along the Y-axis guide groove. When the device uses a torsion spring comparator to measure the bearing ring, it can reduce the force measurement error and eccentricity error existing in the measurement of the thin-walled bearing ring, thereby improving the measurement accuracy of the outer diameter of the thin-walled bearing ring.

Description

technical field [0001] The invention relates to the technical field of outer diameter measurement of bearing rings, in particular to an outer diameter measurement device and method of a thin-walled bearing ring. Background technique [0002] Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Thin-wall bearings are the thinnest in the bearing size series, with extremely light weight, and are widely used in aerospace, radar, precision robotic joints, and precision medical equipment. In the fields of industrial robots and other fields, the bearing capacity of the joints of industrial robots is often relatively large, so more rolling elements are required, and too many rolling elements will cause the circumference of the circle, and because the space at the joints of industrial robots is often limited, bea...
