Fixing and protection device for sphere target of three-dimensional coordinate tracker

Abstract

The invention discloses a fixing and protection device for a target sphere of a three-dimensional coordinate tracker. The fixing and protection device comprises a magnetic sphere base, wherein a magnetic groove is formed in the magnetic sphere base, the groove is used for fixing an objective target sphere, a plurality of horizontal threaded through holes are formed in the periphery of the magnetic sphere base, a bolt is arranged in each threaded through hole, one end of each threaded through hole is positioned in the groove, the lower part of the magnetic sphere base is connected with a vertical rotating shaft, the lower end of the rotating shaft is connected with a rotating block in a movable manner, the rotating shaft rotates around its axis, a horizontally-arranged fixed rod is sleeved in the rotating block, and the rotating block rotates around the axis of the fixed rod; and the lower parts of the fixing rod are connected with fixed bases. The fixing and protection device can guarantee the use of the magnetic sphere base, can further adjust angular positions of the objective target sphere so as to meet different requirements, and improves the measurement efficiency.

Description

technical field [0001] The invention relates to the field of precision measurement, in particular to a fixing protection device for a target ball of a three-dimensional coordinate tracker. Background technique [0002] In the field of precision measurement, laser interferometry technology has become an effective technical means for ultra-precision measurement due to its advantages of non-contact, high precision, and traceability. Measurement occasions. There are many measuring instruments based on laser interferometry technology (for example: laser interferometer, laser tracker), all of which require the cooperation of reflective prisms. The reflectors of trackers with tracking functions generally use spherical reflectors, and their centroids and optical centers coincide. [0003] The laser tracker needs the cooperation of the target ball during the measurement process. If the movement of a certain point is tracked in real time, the magnetic ball seat needs to be adsorbed ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the application of the magnetic ball seat is limited, the measurement conditions cannot be met, and the angle of the target ball cannot be adjusted, thus causing occlusion between the target ball and the laser tracker, and the laser cannot be received and reflected normally. It is to provide a fixed protection device for the target ball of the three-dimensional coordinate tracker, which can ensure the use of the magnetic ball seat, and can also adjust the angular position of the target ball to meet different needs and improve the efficiency of measurement
