Abstract

A measuring apparatus for measuring surface topography of bearing and other parts comprises a pedestal (1), an absolute encoder (2), a ball screw (3), an X-axis sliding guide track device (4), an X-axis limit switch (5), an X-axis signal collection grating (6), a driving box supporting plate (7), a sensor driving box (8), an upright guide track (9), a Z-axis motor (10), a Z-axis manual adjusting knob (11), an X-axis motor (12), an X-axis belt wheel and cog belt (13), an inductive sensor device (14), a sensor coupling rod (15), a multi-dimensional workbench (16) and an electrical system. The invention can measure more than 100 parameters, including profile, waviness, roughness, peak height, valley deepness, total height, average deviation, gradient, slope, bearing length ratio and others; provides detection reference for users to perform various technical analyses to the workpiece to be measured; and can add certain measurement parameter at any time according to the requirement of users.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a measuring instrument which can be used to measure the surface topography of bearings and other parts. Background technique [0002] The machinery industry has achieved 0.001μm feed technology and 0.005μm machining accuracy, which requires detection technology to adapt to it. It is of great social significance to develop surface topography measuring instruments to meet the requirements of advanced manufacturing technology. [0003] At present, the traditional domestic measuring instruments for measuring surface topography such as contour, waviness and roughness have the following defects: [0004] 1. The measurement parameters are single, which cannot meet the requirements of modern manufacturing technology. Domestic similar instruments generally only measure a single parameter such as profile or roughness, which cannot meet the needs of various types of domesti...
