Mounting and measuring device for laser tracker

Abstract

The invention relates to a mounting and measuring device for a laser tracker, which is used for mounting and measuring a double-lug-shaped fixture, and mounting holes are formed in double lugs of the fixture; comprising a measuring shaft, a bushing, a target ball holder, a target ball, a laser tracker, a nut and an insertion plate, an annular groove is formed in the middle of the measuring shaft; the insertion plate is inserted into the annular groove; compared with the prior art, the device has the beneficial effects that the measuring shaft, the target ball mounted on the measuring shaft and the laser tracker are arranged; when the double-lug mounting hole of the fixture is detected, a theoretical center point of the target ball is established on a digital model according to data 'L', 'L1' and 'L2' and a compensation value of the target ball, and detection can be carried out by utilizing a laser tracker.

Description

technical field [0001] The invention relates to the technical field of manufacture and repair of technological equipment in the aviation and aerospace fields, in particular to an installation measuring device for a laser tracker. Background technique [0002] During the use of the frame, the position of the joint is out of tolerance or wrong due to ground changes, relocation or improper use. At this time, the deviation value between the theoretical position size and the actual position size of the working part on the frame is the only input for the design to give a solution according to the deformation situation. Accurate measurement can provide designers with more accurate data theory support, and can give more accurate and reasonable solutions. At present, there are generally three methods for measuring components with higher precision requirements. The first method uses three-coordinate measuring machines and other similar precision equipment. However, tooling is genera...

Problems solved by technology

However, tooling is generally fixed at the work site and cannot be transported, so this type of measuring equipment cannot be used

The second is to use ordinary measuring tools (such as calipers, micrometers, etc.) for measurement. It needs to be equipped with some second-class auxiliary tools according to different detection positions, which prolongs the detection cycle. This type of detection method will also cause accuracy due to tolerance accumulation. poor

The disadvantage is that some measuring sets are required for measurement. When measuring the ears and some special joints, due to the limited space, the working face position cannot be measured. Only the non-working face position can be measured, and then other methods can be used. Converted to the working face position, it is easy to cause errors and make the measurement inaccurate
