Laser tracker plane coordinate high-precision lofting device and method

Abstract

The invention relates to a laser tracker plane coordinate high-precision lofting device and method. The device comprises: a base body which is provided with a target ball supporting part and an accommodating cavity; a base which is arranged on the periphery of the base body and configured to support the base body, wherein the relative position of the base body in the vertical direction is not changed, and the relative position of the base body in the horizontal direction is variable; a dot drawing assembly which is configured to be accommodated in the accommodating cavity; a horizontal adjusting part which is configured to be adjustable relative to the base in the vertical direction; a position adjusting mechanism which comprises a transverse position adjusting device and a longitudinal position adjusting device; and a levelness display instrument which comprises two horizontal bubble instruments which are arranged on the upper surface of the base body and are perpendicular to each other along the center lines in the length direction, wherein the transverse or longitudinal center line of each horizontal bubble instrument does not pass through the other horizontal bubble instrument. According to the method, the lofting coordinates can be accurately scribed, and the precision and efficiency of the particle accelerator on the ground lofting point by using the laser tracker are improved.

Description

Technical field [0001] The present invention relates to a quasi-linear particle accelerator measurement technology, particularly relates to an apparatus and method for high precision laser tracker plane coordinates loft. Background technique [0002] With quasi-collimated particle accelerator component mounting accuracy and standardization of the rising straight installation, most of the quasi-linear accelerator element installation requires complex three-dimensional laser tracker control network to complete collimation. A collimator mounted in a particle accelerator, there is a very critical step is to use the laser tracker to the geometric center of the main geometrical elements and the support element mounting system accelerator loft theoretical coordinate position of the accelerator to the floor or mounting base embedded parts. Measuring principle different from the laser tracker optical measurement instrument, the ground can not be aimed directly at the target point coordina...

Problems solved by technology

There is a problem with this method of stakeout: the target base contacts the stakeout surface. If the stakeout surface is uneven or there are sundries at the bottom of the target base and other factors, it will cause a tilt error of the target base. The target base supports the target ball, because the target base itself The thickness of the laser tracker and the radius of the target ball of the laser tracker will cause the inclination error of the target base to produce a coordinate error of a magnification in the center of the target ball of the laser tracker, and draw a point artificially through the center hole of the target base. The process will also bring errors due to problems such as the alignment of the needle and the hole, and the control of the angle of the needle.

The stakeout error of the position coordinate points of the key components of the accelerator will directly affect the installation accuracy of the accelerator support system. If the stakeout error exceeds the adjustment range of the support system design, it will seriously affect the collimation installation schedule, and then affect the collimation installation of the particle accelerator components. efficiency
