A checking tool for verticality and parallelism accuracy of medium and large vertical bearing housing holes

Abstract

The invention discloses a checking tool for the verticality and parallelism accuracy of medium and large vertical bearing seat holes, which belongs to the technical field of measuring devices and includes a verticality measuring unit, a parallelism measuring unit and an alignment unit. and the parallelism measuring unit both include a moving part and a measuring part, the measuring part is arranged on the moving part, the alignment unit includes a positioning part for determining the measurement positions of the perpendicularity measuring unit and the parallelism measuring unit, the positioning The part is provided with an angle measurement part and a height adjustment part. The invention changes the traditional manual measurement method, through the alignment unit, the automatic measurement is performed after the position is pinpointed, which is simple and fast. The invention has simple structure, easy operation, high alignment accuracy, accurate and efficient measurement, and greatly reduces human error.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, in particular to a measuring tool for verticality and parallelism accuracy of medium and large vertical bearing housing holes Background technique [0002] Perpendicularity and parallelism are among the most important orientation tolerances of a part, both of which are used to control the error between extracted features and derived features. The measured elements of verticality should be kept perpendicular to the datum, the measured elements of parallelism should be kept parallel to the datum, and the error between them should be controlled between two parallel planes. Line-to-line measurement is more complicated than line-to-surface, face-to-face, and face-to-line measurements. It basically measures the accuracy of the hole. Both the reference and the measured elements need to be simulated by the mandrel, and the positional relationship between the two axes is more complicated. Diffi...
