Description

Technical Field

[0001] The invention relates to the technical field of measuring equipment, in particular to an integrated roughness measuring instrument. Background Art

[0002] Roughness measurement is an important quality assessment indicator in industrial production. The roughness meter mainly works on the stylus measurement principle. A tiny stylus is gently scratched on the surface to be measured. Due to the peaks and valleys of the surface profile to be measured, the stylus will move up and down in the vertical direction. This movement is amplified by an electronic device and converted into an electrical signal.

[0003] In the prior art, most of the roughness measuring instruments on the market are divided into contact and non-contact types. The main methods in contact measuring instruments include comparison method, impression method, stylus method, etc. The stylus method is more commonly used and more convenient. The light section method, real-time holographic method, speckle method, optical sensor method, etc. are commonly used in non-contact measuring instruments. The advantages of non-contact roughness measuring instruments are high measurement efficiency and no damage to the surface of some high-demand parts. The disadvantages are that compared with contact measuring instruments, the accuracy is lower and the measurement environment has higher requirements. Most conventional roughness measuring instruments have complex structures, unstable accuracy, low measurement convenience, and relatively high equipment costs. Summary of the invention
