Problems solved by technology

At present, it is an industrial problem to accurately measure large thin-plate parts. If it is placed on a high-flatness horizontal measurement platform, the lower concave surface will be in contact with the measurement platform surface, and the upper convex surface will be suspended, and the lower concave surface will be in contact with the measurement platform. All the weight of the part bears, resulting in artificial contour deformation during measurement, which cannot eliminate the influence of gravity deformation on the accuracy of contour measurement

Abstract

The invention relates to the technical field of measuring large-size sheet type parts, in particular to an adaptive support apparatus and a measuring system using the same, more particularly to an adaptive support apparatus for profile tolerance measurement of a large-size sheet type part. The adaptive support apparatus comprises a measuring mechanism and a support point mechanism. The measuring mechanism consists of a platform, a three-dimensional movement mechanism and a measuring head unit. The three-dimensional movement mechanism is used for driving the measuring head unit to move above the platform. The support point mechanism consists of a plurality of support point units distributed on the platform uniformly; and each support point unit is able to stretch and lift separately. Therefore, the manual contour deformation caused by gravity deformation during the measurement process of the large-size sheet type parts is reduced; measurement of the large-size sheet type parts in a natural stress state is guaranteed; the influence on the contour measurement precision by gravity deformation is eliminated; and thus profile tolerance parameters are evaluated accurately.

Description

technical field [0001] The invention relates to the technical field of measurement of large-size thin-plate parts, in particular to an adaptive support device and a measurement system using the same, and in particular to an adaptive support device for measuring the profile of large-size thin-plate parts. Background technique [0002] At present, for large thin-plate parts, due to their large area, they do not have high rigidity and high stability, and are easily deformed by their own weight. As a result, it is impossible to accurately measure the true shape of the outline of large thin-plate parts during the inspection process, which ultimately reduces the quality of large-scale thin-plate parts. The measurement accuracy of the contour cannot meet the requirements of precise detection. Therefore, a reasonable support is crucial for the precise measurement of the profile of large thin-plate parts. At present, it is an industrial problem to accurately measure large thin-plate...
