Description
Technical field
The present invention relates to volume coordinate field of measuring technique, particularly relate to the gauge head spatial attitude measuring method that a kind of localization by ultrasonic guides.
Background technology
Large-scale metrology and gordian technique are measurement national science state-of-art and the important indicator weighing a national comprehensive strength.At present, large-scale metrology system is made up of two coordinate systems, a coordinate system be made up of Long Distances solid axes, another coordinate system be made up of gauge head coordinate axis, and the coordinate figure of volume coordinate measurement point is determined by the measured value of two coordinate systems.
The measurement of Long Distances volume coordinate is realized by gauge head mobile on guide rail.Because gauge head is subject to the impact of guide rail linearity error in moving process, the axis direction of three coordinate axis of two coordinate systems can not remain the position that is parallel to each other, gauge head is in Long Distances space coordinates, not only there is the measuring error on axis direction, also there is the measuring error etc. produced by anglec of rotation beat and luffing angle beat simultaneously.In addition, gauge head also under the internal stress effect of elastic support and under the effect of flexible support system force unbalance, also can produce the measuring error and various Run-out errors etc. on axis direction in gauge head coordinate system.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides the gauge head spatial attitude measuring method that a kind of localization by ultrasonic guides.
The present invention is achieved by the following technical solutions:
The gauge head spatial attitude measuring method that a kind of localization by ultrasonic guides, include localization by ultrasonic and guide gauge head, described localization by ultrasonic guides gauge head to include flat board, one group of ultrasound emission sensor is fixed with respectively at the tow sides of flat board, often organize ultrasound emission sensor and have four ultrasound emission sensors, dull and stereotyped base is connected with probe, dull and stereotyped top margin is provided with Electromagnetic Launching antenna, described four ultrasound emission sensors of often organizing are encouraged by the ultrasonic frequency of four kinds of different values, the vibration plane normal direction often organizing four ultrasound emission sensors points to the same direction of the dull and stereotyped lateral surface in place, the ultrasonic signal of 4 kinds of different frequency values that localization by ultrasonic guides four ultrasound emission sensors of gauge head one side to send, received by 4 the ultrasonic reception sensors be fixed on pedestal, each ultrasonic reception sensor receives the ultrasonic signal of 4 kinds of different frequency values simultaneously, pedestal is provided with an electromagnetism receiving antenna, receive time reference signal during localization by ultrasonic guiding gauge head attitude measurement, digital filtering is carried out to the composite ultraphonic signal that each the ultrasonic reception sensor be fixed on pedestal receives, obtain localization by ultrasonic and guide the respective independently ultrasonic signal that on gauge head, 4 ultrasound emission sensors send, localization by ultrasonic guides the 3 d space coordinate value of each the ultrasound emission sensor on gauge head, by 4 the ultrasonic reception sensor localizations be fixed on pedestal, the mutual spatial relation between 4 ultrasound emission sensors on gauge head is guided again according to localization by ultrasonic, to obtain the six-degree-of-freedom posture information that localization by ultrasonic guides gauge head space.
Advantage of the present invention is: present invention achieves the direct measurement to gauge head space six-degree-of-freedom posture, eliminate Long Distances guide rail linear degree problem that current large-scale metrology machine side faces and the measuring error that gauge head elastic support internal stress problem on deformation and flexible support system force unbalance problem etc. are brought, improve precision and the reliability of large-scale metrology.
