The invention discloses a laser tracking measurement system with a counterweight balance by taking a standard ball as a reflection device. According to the system of the invention, the problems that alaser head and a connecting plate part in a first-generation laser tracking measurement system have large mass, the rotational motion precision is low, the optical path layout is unreasonable, and alimit installation position is unreasonable, which affect the measurement precision are overcome, and a new laser tracking measurement system design scheme is proposed. A second-generation laser tracking measurement system comprises an optical path carrying platform, a weight balancing device, a pitching motion drive platform, a standard ball fine adjustment device, and a rotational motion drive platform. The laser tracking measurement system with the counterweight balance by taking the standard ball as the reflection device provided by the invention simultaneously reduces the requirement forthe axis precision, and the measurement accuracy is superior to that of conventional laser tracking measurement equipment under the same processing condition and processing cost.
Description
technical field [0001] The invention relates to the field of laser measurement, in particular to a laser tracking measurement system using a standard sphere as a reflection device. Background technique [0002] The laser tracking system is used to measure large-scale geometric dimensions and dynamic trajectories in space, and is an urgently needed measurement device for large-scale scientific engineering and high-end equipment manufacturing. In order to realize spatial dynamic target tracking and measurement, a laser tracking system is required to accurately detect the relative changes in the position of the dynamic target in real time, and perform high-speed servo control through the pitch angle of the tracking control unit. The measuring beam can always ensure fast aiming and tracking of the center of space moving targets, so as to realize real-time tracking and precise measurement of large-scale and long-distance moving targets. The laser tracking measurement system is m...
