Measuring device for elongate assembly of polygonal ball seat

Abstract

The invention relates to a measuring device for elongate assemblies of a polygonal ball seat. The measuring device comprises a vertical supporting base vertically arranged on a horizontal supporting base, wherein a vertical guide rail and a grating rule assembly are parallelly arranged on the vertical supporting base, an upper measurement sliding table, an upper clamping sliding table, an intermediate measuring disc and a lower measurement sliding table which can slide along the vertical guide rail are sequentially mounted on the vertical supporting base from top to bottom, a lower fixing basewith adjustable planar position is further arranged on the vertical supporting base, a spherical surface supporting base is fixed on the lower fixing base, coaxial mounting through holes used for mounting the measured elongate assembly are formed in the upper clamping sliding table, the intermediate measuring disc and the spherical surface supporting base respectively, the spherical surface supporting base is used for mounting the ball seat of the measured elongate assembly, the upper clamping sliding table is used for clamping and positioning the upper part of the elongate assembly, and theupper measurement sliding table, the intermediate measuring disc and the lower measurement sliding table are provided with measurement sensors corresponding to different measured parts respectively.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a measuring device for a polygonal ball seat slender assembly. Background technique [0002] To accurately measure the size and shape tolerances of components, a three-dimensional coordinate measuring machine is generally used. At present, the common three-dimensional coordinate measuring machine on the market has a certain limitation in the measurement range (generally within 3m). For the special shape and structure of the measured component, such as the measurement of some large-sized and slender parts, especially the measurement similar to hexagonal For slender parts such as ball seats with polygonal structures, if the measurement range is forcibly increased, the accuracy will be greatly reduced. [0003] For this type of component, it also involves the problem of clamping method. The traditional three-coordinate measuring machine uses horizontal measurement, and ...
