Abstract

The invention belongs to the technical field of measuring instrument production and measurement, in particular a complex revolving body contour measuring method and device capable of eliminating part positioning error. The device comprises a vertical guide rail system consisting of a first measuring head and a second measuring head including an emitter capable of emitting parallel lights and a receiver formed by a high-accuracy linear array CCD, a revolving workbench, a base, a vertical guide rail and a floating frame. A revolving body workpiece to be measured is arranged on the revolving workbench, the first measuring head and the second measuring head can move up and down along with the floating frame along the vertical guide rail and are symmetrically and radially distributed at both sides of the revolving body workpiece to be measured, and the measuring range of the measuring heads is larger than the radius variable of the revolving body component to be measured. When a complex revolving body is measured by the method and the device, the influence of the part positioning error can be effectively and automatically eliminated, and the contour size and error of the complex revolving body can be fast measured.

Description

technical field [0001] The patent of the invention belongs to the technical field of measuring instrument manufacturing and measurement, in particular to a method and device for measuring the contour of a rotating body that can eliminate part positioning errors. Background technique [0002] The invention proposes a general rapid measurement method for measuring the profile of a complex revolving body, which is mainly used for the rapid measurement of the profile of a complex revolving body. [0003] For the profile of a complex rotating body, its fast and accurate measurement has always been a relatively difficult problem to solve. The existing methods for measuring the profile of a rotating body can be roughly divided into three types: [0004] 1. Contour template method: This method can only judge whether the contour of the rotating body is qualified or not, and cannot give the error size. At the same time, the method is affected by the operator, and the measurement acc...
