Abstract

The invention discloses a special worktable for a laser tracker, which is capable of moving the laser tracker to an extension line of the link between the point A and the point B to the utmost extent and keeping the pointing direction of the laser track consistent with the link between the point A and the point B to the utmost extent when in measurement of the distance between the point A and the point B in the three-dimensional space. The special worktable for the laser tracker comprises a mount, a vertical angle regulator, a horizontal angle regulator, a horizontal translation regulator and a lifting regulator, wherein the mount is matched with a base of the laser tracker, the vertical angle regulator, the horizontal angle regulator, the horizontal translation regulator and the lifting regulator are used for regulating the mount. The interferometry function of the laser tracker can be utilized by the worktable during measurement, horizontal rotation and vertical rotation of the laser tracker are avoided, and accordingly uncertainty in measurement of the laser tracker is reduced, and measurement precision of the point A and the point B is guaranteed. In addition, the invention further discloses a laser tracking measurement method.

Description

technical field

[0001] The invention relates to a special workbench for a laser tracker and a laser tracking measurement method. Background technique

[0002] Among the existing portable, large-scale space measurement equipment, the laser tracker is the most accurate. For example, the measurement uncertainty of a certain type of laser tracker produced by the American API company reaches 0.005 mm / m, and its measurement range is 0-60 meters. However, when the measurement range exceeds 20 meters, the measurement uncertainty will reach 0.1 mm, and with the increase of the measurement range, the measurement uncertainty will also increase linearly. However, a certain part is a part with a length of more than 30 meters and requires ultra-high precision, so the above-mentioned laser tracker cannot meet its measurement precision requirements. Contents of the invention

[0003] In order to overcome the above limitations of the laser tracker, the inventors of the present applicatio...
