Non-contact type on-line measurement device and method of large-size bearing roller way

Abstract

The invention relates to non-contact type on-line measurement device and method of a large-size bearing roller way in the technical field of measurement. The device comprises a laser displacement sensor, a fixing device, a data acquisition module and a data processing module, wherein the laser displacement sensor is connected with the data acquisition module for transmitting distance point range data, and the data acquisition module is connected with the data processing module for transmitting the distance point range data of the laser displacement sensor; and the fixing device is respectively connected with the laser displacement sensor and a numerical control machine. The method comprises the following steps of: mounting the device on a knife rest of the numerical control machine; scanning a bearing roller way plane by utilizing the knife rest of the numerical control machine to drive the laser displacement sensor; and processing data to acquire the shape and parameters of the crosssection of the bearing roller way and obtain the shape deviation of the bearing roller way plane. The invention realizes non-contact on-line measurement, enlarges the application range, meets the requirements of bearing measurement and effectively improves the precision and the efficiency of the measurement of the bearing roller way plane.

Description

technical field [0001] The invention relates to a device and method in the field of measurement technology, in particular to a non-contact online measurement device and method for large bearing raceways. Background technique [0002] Rolling bearings are widely used and demanding supporting parts and basic parts in the machinery industry, and are called mechanical joints. Especially in recent years, the wide application of wind power generation, etc., makes the demand for large bearings continue to increase. The bearing manufacturing industry is a kind of precision basic parts manufacturing industry. Its accuracy is measured by 0.001mm, while the manufacturing tolerance of ordinary mechanical parts is generally only 0.01mm. Therefore, in actual production, the matching method is usually used, which puts forward higher requirements for the detection accuracy of the bearing profile. The detection of the inner and outer rings of bearings in our country after processing is alm...

Problems solved by technology

However, the measurement devices used in this device are also mainly contact type, and only small and medium-sized bearings are measured, and the measurement of the outline of large bearings cannot be realized; moreover, this technology still adopts the means of offline measurement, and the inspectors and workers use dial gauges and other equipment Inspection, not only the measurement error is large, but also needs to be re-clamped and processed after the error is found, which is not conducive to timely correction when the error is found
