Abstract

The invention provides a composite type precision measurement method for large components. The method comprises the steps that a transit measuring system is set up; an online detection and repairing device measuring system is set up, the transit measuring system and the online detection and repairing device measuring system are used for measuring a common reference ball for obtaining measurement data; according to the measurement data, a transit measuring coordinate system of the transit measuring system and a machine tool measuring coordinate system of the online detection and repairing device measuring system are converted to one coordinate system. The method is conducted through the online detection and repairing device measuring system and the transit measuring system, through the combined measurement technology, the measurement requirement of the satellite products at the assembling stage is met, and the requirements for the measurement precision and measurement performance are well met. The non-contact type measurement technology and the contact type measurement technology are combined and achieved as a whole under the composite measurement system, and the method has wide application prospects in the spaceflight field.

Description

technical field [0001] The invention relates to the technical field of industrial measurement, in particular to a composite precision measurement method for large-size components. Background technique [0002] The main measurement methods used in the measurement of space coordinates of large-sized workpieces of spacecraft are contact and non-contact. Contact measurement equipment is represented by online inspection and trimming equipment or three-coordinates; non-contact measurement is represented by optical electronic theodolite. However, when these two measuring devices work independently, there are some unavoidable shortcomings due to the limitations of the inherent functions of the devices: [0003] (1) Contact measurement method [0004] Represented by on-line inspection and dressing equipment or three-dimensional coordinates, the advantages are that the measurement range is large, the versatility is strong, and the CNC machining program can be generated in real time ...
