Abstract

The invention discloses a device for measuring the contour of a mechanical part, and relates to the technical field of industrial measurement. The device comprises an object space telecentric system and an image space telecentric system; the object space telecentric system is a front fixed group, and image space telecentric system comprises a zoom group, a compensation group and a rear fixed group. The device keeps the magnification of an object image space unchanged within a unit working distance by moving the zoom group and the compensation group and simultaneously linking the two groups. The object space telecentric system can eliminate errors caused by inaccurate focusing of the object space, and the image space telecentric system can eliminate measurement errors caused by inaccurate focusing of the image space. The image space telecentric effect is combined with the irradiation of a backlight source, so that the contour images of the parts with different sizes (30-90mm) processedon line can be collected into a computer in real time through an image system and compared with a processing drawing, the detection and correction of the surface contour of the product can be visuallyand clearly completed, the processing efficiency of workers is comprehensively improved, and the measurement precision is ensured.

Description

technical field [0001] The invention relates to the technical field of industrial measurement, in particular to a profile measuring device for mechanical parts. Background technique [0002] There are many domestic tool and gear processing enterprises, and profilers are widely used in production and processing. The traditional profiler mainly uses projection lens imaging to observe, and the sensitivity of the detection instrument is not high. For different sizes of shafts, gears, tools, splines, gaskets and other parts, each profiler is equipped with a lens with a fixed magnification lens, and limited by the field of view, the magnification is not fixed at different object distances, and the comparison error is large. Therefore, the existing equipment has the problem of relatively large errors. Contents of the invention [0003] The purpose of the present invention is to provide a profile measuring device for mechanical parts, which solves the problem of large errors in ...
