A target ball fixing device for a laser tracker and its application

Abstract

The invention discloses a target ball fixing device of a laser tracker and application of the target ball fixing device. The target ball fixing device comprises a fixed support and a movable support, the movable support is embedded in an inner groove of the fixed support, two spring grooves are formed in the inner groove of the fixed support, a spring is arranged in each spring groove, one end of each spring is fixedly connected with the fixed support, and the other end of each spring is fixedly connected with the movable support; a target ball fixing seat groove is also formed in the upper end face of the fixed support. Due to the fact that the target ball fixing device of the laser tracker enables the target ball to be positioned at the key point, required to be collected, of a measuring system, an approach is provided for the measuring of urban rails and collection of point positions of railway track geometry model of the laser tracker, and therefore the target ball fixing device of the laser tracker solves the problem of application to high-accuracy geometry model position detection of the laser tracker, fills in the gaps of application to high-accuracy rail geometry model position detection of the laser tracker, and has a significant progress and application prospect.

Description

technical field [0001] The invention relates to a target ball fixing device of a laser tracker and an application thereof, in particular to a target ball fixing device of a laser tracker which can be used to accurately measure the geometric position of a track, and belongs to the technical field of laser detection. Background technique [0002] High-speed rail has the characteristics of large volume, fast speed, and long journey. It is closely integrated with the needs of my country's economic development and people's livelihood, and is the pillar of my country's transportation development. However, as the speed of high-speed rail continues to increase, the track requirements for the railway foundation are also more stringent. With the gradual popularization and application of ballastless track, the key technology of track precision measurement is placed in a very important position. Only by ensuring the track accuracy can the comfort and safety of the train running at high...

Problems solved by technology

[0004] However, laser trackers are mostly used in industries such as aerospace, automobile manufacturing, electronics industry, high-energy particle accelerator engineering, and large-scale metrology. It is still in the early stage of development in track measurement. For special applications such as track, how to realize the acquisition point The positioning of the target ball is very important to achieve high-precision measurement, but there is no relevant report on this technology at present, and it is urgent to solve this problem in this field
