Centering roller ball base surface size measuring device

Abstract

The invention discloses a centering roller ball base surface size measuring device which comprises a fixing base, wherein the fixing base is 'L'-shaped; a dial gage is fixed in the position of the corner of the fixing base; a first measuring head is arranged at the lower end of the dial gage; a second measuring head, a swinging rod and a measuring rod are arranged at one end of the fixing base; aspring is arranged at the other end of the fixing base; the second measuring head, the swinging rod and one end of the measuring rod are fixedly connected into an entity; the entity is in shaft connection with one end of the fixing base; one end of the swinging rod is connected with one end of the spring; a steel wire rope is arranged between the swinging rod and a grinding wheel shaft tank. The first measuring head is in contact with the measuring rod, the second measuring head is in contact with a roller ball base surface, a roller is ground by using a grinding wheel, the second measuring head is moved forwards along with the grinding process, then the position of the measuring rod is also changed, data of the first measuring are displayed through the dial gage along with position changeof the measuring rod, and the grinding size of the grinding wheel upon the roller can be judged by operators according to the data. The device has the most significant beneficial effects that size requirements of a ball base surface can be met at one time.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a device for measuring the base surface size of self-aligning roller balls. Background technique [0002] The existing method for measuring the ground surface of spherical roller bearings is to use calipers, R templates and profilers to measure, and one roller needs to be measured more than twice during the grinding process. In order to ensure the uniform size of each roller ball base surface of a set of bearings, workers must have a high technical level, and it is labor-intensive and time-consuming. It is very difficult to achieve a uniform size deviation of a set of roller ball base surfaces, causing some The size of the base surface of the roller ball has a large dispersion and cannot be matched with the group. Contents of the invention [0003] The invention provides a size measuring device for the base surface of the self-aligning roller, which aims to solve the problems of high r...

Problems solved by technology

[0003] The invention provides a measuring device for the size of the spherical base surface of the self-aligning roller, which aims to solve the problems of high requirements for workers, difficulty in unifying the size, and too large size deviation to match the group when the self-aligning roller grinds the ball base surface.
