Roughness measurement device and method

Abstract

The invention relates to a roughness measurement device and method, and belongs to the technical field of test equipment. A rotary motor with a downward output is mounted on a bracket of the device, the output shaft is fixedly connected with a cylinder body seat provided with an air cylinder, the lower extending end of the air cylinder is fixedly connected with an upper pressing plate, the upper pressing plate and a lower pressing plate form a vertical moving pair through a vertical guide mechanism, a pressing spring with adjustable elasticity is mounted between the upper pressing plate and the lower pressing plate, a roughness measurement head is mounted below the lower pressing plate, an elastic buffer is mounted on the side of the roughness measurement head, wherein the fixed end of theelastic buffer is fixedly connected to the lower pressing plate, and the lower end of the buffer is lower than the measurement head and the elastic rigidity is less than the pressing spring. The roughness measurement device and method can be completely automatic, the efficiency is high, and the influence of human factors on a measurement result is avoided. Accuracy and reliability of the measurement result are ensured. In addition, pressing elasticity and buffering elasticity can be adjusted separately, good protective action can be played on the measurement head, and the measurement head further can be in an optimal measurement state.

Description

Technical field [0001] The invention relates to a measuring device, in particular to a roughness measuring device, and also to a corresponding measuring method, belonging to the technical field of testing equipment. Background technique [0002] For a long time, the surface roughness of metal plates has been measured by a handheld measuring instrument. In order to test the roughness data of each test point of the plate in different rolling directions, it is necessary to perform multiple indexing measurements at each test point, which is not only inefficient, but also measurement The result is easily affected by human factors. Although technical innovations in measuring roughness are not uncommon, for example, Chinese patent documents with application numbers 201310240082.2, 201610837588.5, and 201811267779.8 respectively disclose a measuring table and measuring method for measuring the surface roughness of thin steel sheets, and a surface roughness Measuring device, an automatic...
