Abstract

The invention discloses a contact type two-cylinder axis crossing angle automatic measuring device. The device is composed of a device platform, a detecting device and a driving device. The device platform has the functions of supporting and fixing. The device platform can effectively support the detecting device and the driving device. A radial circular grating is placed on the edge of the circumferential guide rail of the device platform to effectively automatically measure and control angular displacement. The device can be applied to test pieces of different sizes, has a wide application range, and can meet different experimental needs. The detecting device can monitor the magnitude of applied force in real time, is convenient for studying the mechanical properties of a joint surface,and has the advantages of simple installation method, clear principle, automatic control and easy operation.

Description

technical field [0001] The invention relates to the field of joint surface experimental measurement, in particular to controlling and measuring the variation of the axis crossing angle when the joint surface is in contact with each other under a certain force condition, and in particular to a contact type cylinder axis crossing angle automatic measuring device. measuring device. Background technique [0002] Studies have shown that the stiffness of the joint surface in the machine tool accounts for about 60% to 80% of the total stiffness of the machine tool, and the contact damping of the joint surface accounts for more than 90% of the total damping of the machine tool. How to obtain the mechanical properties of the joint surface has always been a research problem. In the existing joint surface research, based on their respective irregular rough surfaces, the researchers used parameters such as processing methods, surface roughness, fractal and statistics to classify and de...
