The invention relates to a three-dimensional cross hole position degree detection instrument and a detection method, which belong to the technical field of part detection and solve the problem that the existing detection device cannot accurately detect the position degree of the three-dimensional cross hole parts. The present invention is provided with a first mobile station, the first mobile station includes a first slide rail and a first slider; the first slide block is provided with a second mobile station, and the second mobile station includes a second slide rail and a second slide block; The first slide rail and the second slide rail are orthogonal; the second slide block is equipped with a precision slide table, and the round hole parts are installed in the measurement area on the top of the precision slide table; the first slide rail is equipped with a first camera and a third camera facing each other , used to take images of the sidewall holes in the first direction of the round hole parts; the second slide rail is provided with a second camera and a fourth camera, used to take images of the sidewall holes in the second direction of the round hole parts. For the detection of the position degree of holes specially distributed in small-sized parts, the application improves the detection accuracy, efficiency and reliability of detection.
Description
technical field [0001] The invention relates to the technical field of part detection, in particular to a three-dimensional cross hole position degree detection instrument and detection method. Background technique [0002] For industrially produced hole parts, the position error will have a significant impact on the connection strength, sealing, life, processing noise, working accuracy and motion stability of the assembly. [0003] The traditional methods of detecting position mainly include mechanical alignment method, optical alignment method and laser alignment method. The mechanical alignment method usually uses steel wire or gauge as the benchmark for actual measurement, but the problem with this method is that the benchmark There will be deflection and deformation of the gauge itself, and the wear resistance of the gauge or steel wire will be reduced due to long-term repeated use. The detection accuracy of this method is not high, and it cannot meet the high-precision...
