Description
Technical Field
[0001] The utility model relates to the field of bearing groove measurement, in particular to a contact type bearing groove measuring device. Background Technique
[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. When a bearing is produced, its raceway needs to be measured, and at this time, a bearing groove measuring device is required.
[0003] When measuring the bearing raceway, a steel ball and a micrometer are usually used, and then the median value is obtained by conversion according to the drawing size. However, the roundness of the inner raceway of the bearing and the same-size deviation of the double raceways cannot be measured. Moreover, in this measurement process, the operation process is relatively cumbersome. It is necessary to first measure the outer diameter of the bearing, place steel balls of the same specification in the inner raceway, and measure the value of N. During the measurement, due to the manual gesture measurement error and reading error of the outer diameter size and the value of N, the value obtained after conversion is often deviated, resulting in low accuracy of the measured size. And in the whole measurement process, the detection rate is too slow and it takes a long time. Therefore, a contact type bearing groove measuring device is proposed for the above problems. Content of the Utility Model

At this time, the measuring head 7 contacts the inner wall of the workpiece. Then, as the measuring head 7 moves, the measuring head 7 contacts the bearing groove. At this time, the second clamp body 2 opens slightly. At this time, by observing the numerical change range of the dial indicator 6, the median value of the bearing groove, the roundness deviation, and the same large value deviation between two adjacent raceways can be measured quickly and accurately by two measurements, improving the detection accuracy and the inspection efficiency.
