Position calibration system for triaxial motion equipment

The invention belongs to the technical field of triaxial motion equipment, and provides a position calibration system for triaxial motion equipment. The position calibration system is used for solvingthe problem of inaccurate positioning needing calibration caused by the deviation of an initial position of the triaxial motion equipment during operation. The position calibration system comprises atransverse beam, a triaxial motion mechanism, a detecting switch, and blocks. The detecting switch is mounted on the triaxial motion mechanism. The blocks are mounted on the transverse beam and are used to trigger the detecting switch, so as to realize automatic position detection and information transmission. The technical scheme of the position calibration system for the triaxial motion equipment realizes the automatic and convenient calibration of the initial position of the triaxial motion equipment, which is simple and accurate in operation, and avoids the instability and complexity brought by an operator. 一种三轴运动
