Strain-gauge-based coaxiality adjusting system and coaxiality dimension reduction adjusting method

Abstract

The invention relates to a strain-gauge-based coaxiality adjusting system and a coaxiality dimension reduction adjusting method, and belongs to the field of coaxiality calibration. The whole strain-gauge-based coaxiality adjusting system is arranged on a vertical tensile testing machine, and comprises a main shaft loading chain, a coaxiality adjusting device, a detection and feedback device and aframe, wherein the coaxiality adjusting device is arranged on the main shaft loading chain; the main shaft loading chain is arranged on the frame; and the detection and feedback mechanism is arrangedon the frame for detecting and controlling the adjusting amount. The adjustment of five degrees of freedom can be realized, and meanwhile an adjusting bolt is indexed. Different kinds of centering sensors are applied to make good for deficiency, and a loading chain can be detected and adjusted at five degrees of freedom only by a five-dimensional centering sensor. A centering device is directly connected with the loading chain, and flange connection is adopted for improving the strength, so that the strength and rigidity of the device are improved. The strain-gauge-based coaxiality adjusting system has the advantages of high adaptability, capability of matching a plurality of fixtures, small occupied space, easiness in operation and repeated adjustment. The experiment accuracy can be improved, so that measured data are more accurate.

Description

technical field [0001] The invention relates to the field of coaxiality calibration, in particular to a strain gauge-based coaxiality adjustment system and a coaxiality dimensionality reduction adjustment method. Installed on the testing machine to adjust the coaxiality of the loading chain. Background technique [0002] With the development of the economy and the advancement of science and technology, the testing machine industry is booming like mushrooms after a rain, and various testing machines for different purposes are emerging. The testing machine can measure the mechanical properties, process properties, internal defects of materials and check rotating parts. Dynamic unbalance and other aspects, and more and more widely used in machinery industry and other fields. The coaxiality adjustment method of the traditional testing machine is manual adjustment, but the efficiency of manual allocation is low, and the standard is different, the adjustment amount is limited, an...
