Abstract

The invention relates to the field of laser measurement, and in particular to a magnetic laser tracking head. Compared with traditional laser tracking heads that use staggered rotation axes to control laser tracking mirrors, the magnetic laser tracking head provided by the invention uses inlaid magnetic rings and The moving magnetic ring cooperates to achieve non-contact rotation. During the movement of the hemispherical mirror in the laser tracking head, its spherical center is only related to the accuracy of the hemispherical mirror body and the fixed spherical shell, and has nothing to do with the accuracy of the moving guide rail, which simplifies The existing laser tracking device improves the system accuracy.

Description

Technical field [0001] The invention relates to the field of laser measurement, in particular to a magnetic laser tracking head. Background technique [0002] Laser tracker is a high-precision large-size measuring instrument in industrial measuring system. It has the characteristics of high accuracy, high efficiency, large measurement space, and easy to use. It is widely used in automobile manufacturing, shipbuilding, aircraft manufacturing, aerospace and other fields. The laser tracker is actually a combination of laser interferometric ranging and automatic tracking total station, usually composed of laser head, laser tracking head, target mirror, environmental compensator and other accessories; traditional laser tracking head uses staggered rotation axis Realize the problem of poor control accuracy of laser tracking mirror. Summary of the invention [0003] The purpose of the present invention is to overcome the problem of low control accuracy caused by the prior art laser tra...
