The invention discloses a large-size cylindrical part plain line straightness error detection device and method. The device comprises a wire pressing device and a wire pulling device which are arranged at the two ends of a measured cylinder respectively, a steel wire rope is connected between the wire pressing device and the wire pulling device, the wire pressing device is used for clamping one end of the steel wire rope, and the wire pulling device is used for straightening the steel wire rope. The device further comprises a galvanometer, a laser, a camera and a calculation module. The laseris used for emitting linear structure light. The galvanometer is used for reflecting light emitted by the laser to the surface of the measured cylinder. The camera is used for collecting image data ofthe measured cylinder, and the calculation module is used for receiving and processing data acquired by the camera. The device is used for solving the problems of high difficulty in detecting the straightness of the plain line of the large-size cylindrical part, complex detection process and low detection precision in the prior art, and achieves the purposes of convenience in carrying, wide application range and high measurement precision.
Description
technical field [0001] The invention relates to the field of measurement, in particular to a device and method for detecting the straightness error of the element line of a large-size cylindrical part. Background technique [0002] Cylindrical parts are a typical part in engineering. They are widely used in navigation, aviation, automobiles and other fields. They are indispensable basic parts in the machinery manufacturing industry, such as machine tool spindles, gears, motor rotors, weapon systems in manufacturing The barrel and other parts in the machine are all machined from cylindrical blanks. In order to measure the manufacturing accuracy of cylindrical parts, it is usually necessary to detect the straightness error of its prime line, so as to accurately evaluate its surface shape error. For the detection of the straightness of the plain line of cylindrical parts, precision measuring equipment such as three-coordinate measuring machines and roundness meters are commonl...
