The invention relates to an on-machine measuring device and method for rotary curve contour machining. The on-machine measuring device for rotary curve contour machining comprises a displacement detection unit, a laser beam calibration unit and a laser beam incident angle control unit. The on-machine measuring device for rotary curve contour machining is characterized in that the displacement detection unit comprises a laser displacement sensor and a sensor controller, the laser displacement sensor is installed on the laser beam calibration unit, and is connected with the sensor controller, the laser beam calibration unit is installed on the laser beam incident angle control unit, and the laser beam incident angle control unit drives the laser displacement sensor to rotate by an appointed angle. The on-machine measuring method for rotary curve contour machining comprises the step that when a curve contour is measured, the laser beam incident angle control unit controls a laser beam to rotate by the corresponding rotation angle so that the laser beam can carry out incidence in the normal direction of the contour of a workpiece. According to the on-machine measuring device and method for rotary curve contour machining, the number of steps of installation and disassembly of the workpiece on a machine tool is reduced, measuring accuracy is improved, and thus processing efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of mechanical processing and precision measurement, in particular to an on-machine measuring device and method for rotary curved profile processing. Background technique [0002] For some rotary curved profile parts with complex shapes, such as radome, if the geometric quantity requirements such as internal and external contours and wall thickness are high, in order to minimize waste products, a certain margin is usually reserved after finishing, and the three-coordinate Measuring machines, roundness meters and other precision instruments are used for off-line measurement and then judged. If it is out of tolerance, install the workpiece on the machine tool again for processing to further improve the machining accuracy of the workpiece. Therefore, the workpiece needs to be installed and debugged multiple times between the measuring station and the grinding station, and there are many intermediate conversion ...
