Abstract

The invention relates to the filed of coiled profile supplied to a machine and diameter measurement, in particular to a device and a method for coiled material centering and diameter measuring. The device comprises a dolly, a hydraulic cylinder, a mandril and a bracket. The hydraulic cylinder is fixed on the dolly which can move leftwards and rightwards; the mandril is fixed on the piston of the hydraulic cylinder; and the bracket is fixed on the top of the mandril. The device is characterized by also comprising a displacement sensor A, a photoelectric sensor B, a photoelectric sensor C, an analog / digital converter and a PLC; the displacement sensor A is fixed inside the mandril; linear relation exists between position signals generated by the displacement sensor A and the movement distance of the mandrill; the photoelectric sensor B and the photoelectric sensor C are fixed above the bracket and positioned on the same horizontal line; and the displacement sensor A, the photoelectric sensor B and the photoelectric sensor C are all connected with the PLC through the analog / digital converter. The invention has the advantages of simpleness, reliability, convenient installation and high control and measurement accuracy and is beneficial to quantitative statistic.
