Ball diameter automatic measurement device and method

Abstract

The ball diameter automatic measurement device according to the present invention preferably comprises a displacement sensor, a dividing plate, a slider and a measurement controller. The displacement sensor measures the diameter of a ball positioned in a measurement position. The dividing plate holds a ball to be measured and reciprocates the same between a predetermined position and the measurement position. The slider rotates the ball in the predetermined position by a predetermined angle when the dividing plate is moved. The measurement controller stores and outputs measured values obtained by repeated measurement and measurement after the rotation of the predetermined angle. According to the device, it is possible to measure a ball diameter accurately without being influenced by body temperature, air temperature and individual workmanship when the diameter of a ball is measured.
