The invention belongs to the technical field of rotor inspection and detection, and discloses a rotor inner hole measuring method and device, and the method comprises the steps: setting an avoiding radian distance of a vertical groove; determining a measuring point outside the avoiding area of the vertical groove; putting a control measuring pin into the inner hole of the rotor for measurement, keeping away from the avoiding area of the vertical groove, and recording an air pressure sudden change position; the middle position between the two annular grooves is determined according to the starting position and the stopping position of each air pressure sudden change; the middle position between every two annular grooves is used as a unified positioning surface for measurement; selecting the maximum calibration device and the minimum calibration device corresponding to the tolerance range to calibrate and calibrate the measuring instrument according to the diameter of the inner hole of the rotor and the tolerance allowable range; and calculating the difference between the theoretical size of the inner diameter of the minimum calibration device and the measured value of the inner diameter of the minimum calibration device. The detection precision of the non-standard equipment rotor inner hole detection device can be improved.

The utility model relates to the technical field of continuous casting machine radian measurement, in particular to a continuous casting machine radian measuring device which comprises a radian measuring frame, the bottom of the radian measuring frame is fixedly connected with a height adjusting seat, and the right side of the radian measuring frame is fixedly provided with a first driving motor through a fixing frame. The output end of the first driving motor is fixedly connected with a threaded supporting rod, the surface of the threaded supporting rod is in threaded connection with a threaded sleeve plate, and the top of the threaded sleeve plate is connected with a limiting assembly. The height of the base is adjusted according to an adjustment scheme generated by analysis of a measurement result to form latest radian data, and the data of the base are finely adjusted again according to a review result, so that the practical tracking effect of measurement alignment and correction and remeasurement of the radian of the continuous casting machine can be realized.

This invention relates to the field of ring rolling mill technology, and particularly to a method and system for controlling the ellipticity of a ring rolling mill based on dynamic ellipticity detection. The method includes: using a laser rangefinder to collect the laser distance at measurement point i of the ring in real time, obtaining the ring wall thickness at measurement point i; using a main roller encoder to obtain the radian coordinates of measurement point i; calculating the outer diameter, inner diameter, and middle diameter of the ring; calculating the ring radius, original reference radius, and effective radius at each measurement point i; calculating the length of the major and minor semi-axis of the ring, and then calculating the ellipticity; determining whether the ellipticity meets the set value; if not, calculating the core roller compensation amount and performing radial compensation; and repeating the above steps until the ring is processed according to a preset diameter increase and height / wall thickness processing program. This invention improves the processing efficiency and forming quality of the ring.
