The measurement accuracy of the detection mechanism is related to whether the radial clearance index of the inner ring after the steel ball is selected and assembled meets the process requirements. This mechanism mainly contacts the upper and lower raceways of the inner ring through the detection mechanism through a high-precision displacement sensor. The upper and lower double-row detection steel balls simultaneously detect the two raceways of the inner ring. The displacement sensor automatically reads the comprehensive value of the inner ring double raceways. The precision of the precise measurement is more realistic and the detection error is smaller. The computer then calculates the size of the outer ring and steel ball that match it, and realizes the purpose of automatic detection, effectively preventing various factors from causing errors in the detection data, making the detection results more accurate, and realizing full automation, greatly reducing the labor intensity of workers, improving positioning accuracy, greatly improving production efficiency, and ensuring the quality of finished products.
