Problems solved by technology

However, according to the applicant, although the detection device can automatically detect the radial clearance of the bearing during use, there are still some shortcomings: the processing of the mandrel and the matching accuracy of the detection device with the inner ring of the bearing The requirements are very high, it is difficult to achieve automatic fast clamping, the measurement efficiency is low, and after a long period of use, the matching accuracy of the mandrel and the inner ring of the bearing will be reduced due to wear, which will increase the measurement error, and the mandrel needs to be replaced regularly. Increase the production cost; at the same time, the detection device is aimed at the measurement of the radial clearance of the bearing as a whole, using an indirect contact method, and measuring by pushing the inner and outer rings of the bearing left and right. As we all know, there is a gap between the inner and outer rings of the bearing and the rolling elements inside. A certain gap error affects the accuracy of the test results to a large extent

Abstract

The invention relates to a radial-displacement numerical control detection apparatus of a bearing retainer and a rolling body. The apparatus comprises a pedestal, an upper molded component and a lower molded component whose one end is installed on an elevator mechanism respectively. The upper molded component is provided with an upper pressing mold used for positioning a detected retainer. The lower molded component is provided with a lower pressing mold used for positioning the detected retainer. A measurement pen which is contacted with the rolling body in the detected retainer is installed on a tail end of the upper molded component through a clamping rack, and a front elastic pressing mechanism and a rear elastic pressing mechanism, which are used for pushing and pressing the detected rolling body, are located on an outer side and an inner side of the lower pressing mold. Two guide pillars are symmetrically arranged between the upper molded component and the lower molded component. By using the apparatus of the invention, automatic positioning and rapid clamping of the detected retainer can be realized; the front elastic pressing mechanism and the rear elastic pressing mechanism are used to direct push and press the rolling body and measure radial-displacement of the rolling body and the retainer; an error generated because of mandrel wearing and indirect bearing measurement in a traditional measurement mode is avoided; operation is stable; measurement efficiency and precision are high and a suitable scope is wide.

Description

technical field [0001] The invention relates to the field of bearing detection equipment, in particular to a numerical control detection device for the radial movement amount of a bearing cage and a rolling body. Background technique [0002] Bearing is a product with a large quantity and a wide range. To ensure the quality of the bearing, it is necessary to measure its various technical parameters, and the radial movement of the bearing cage and rolling elements is one of the important testing items for the finished bearing. It refers to The gap between the rolling elements of the bearing and the matching inner and outer ring channels is the grease lubrication gap and rolling gap for different use occasions and different types of bearings. The radial clearance of all types of bearings is required to be within a certain range. The test results will directly affect the running performance of the bearing, especially the impact on noise, vibration and service life. [0003] At...
