Self-adaptive steel ball sorting device based on electric eddy current testing

Abstract

The invention relates to a self-adaptive steel ball sorting device based on electric eddy current testing. A steel ball sorting unit comprises two sorting rollers which are parallel. The two storing rollers are both in the step type. The electric eddy current testing unit comprises two groups of electric eddy current sensor, a colpitts oscillator, a testing circuit and a MCU microprocessor, wherein the two groups of electric eddy current sensor, the colpitts oscillator, the testing circuit and the MCU microprocessor are electrically connected. The two groups of electric eddy current sensors are arranged at the two ends of the two sorting rollers in pairs. The axes of the electric eddy current sensors and the axes of the two sorting rollers are located on the same plane. The spherical errorof steel balls reaches 0.08 micron, and the sorting efficiency can reach 15000 balls per hour; and in this way, the sorting efficiency is higher, and the diameter error rate of the steel balls is more accurate.

Description

technical field [0001] The invention relates to a sorting device for steel balls, in particular to an adaptive sorting device for steel balls based on eddy current detection, which belongs to the field of machinery. Background technique [0002] The polished steel balls need to be sorted by size, and the steel balls of each type are classified to facilitate further testing. In the traditional process, the sorting of steel balls needs to rely on the experience of workers to adjust the distance of the sorting rollers. Workers need special training and are easily affected by subjective factors. The quality of steel balls is difficult to guarantee and the degree of standardization is low. The method of manually adjusting the distance between the sorting rollers makes the precision of steel ball sorting low, and the equipment needs repeated debugging, the sorting efficiency is low, and the degree of self-adaptation of the equipment is low.
