Problems solved by technology

Nowadays, when measuring the microscopic topography of the steel plate surface, light-section microscopes are often used. However, when adjusting the height of the light-section microscopes currently used, most of them are carried out by plugging in. For example, the patent application number is CN201320853409.9 , a Chinese utility model patent titled "Multifunctional Integrated Optical Sectioning Microscope", there is a height adjustment blind spot when it is used, and the measuring table can only be adjusted back and forth, which is inconvenient to use

Abstract

The invention discloses a light-sectioning microscope for measuring the surface microstructure of a steel plate, and relates to a light-sectioning microscope. A supporting column fixed to a platform is equipped with a hollow cavity, and is provided with a sliding groove in a side surface, a support is sleeved on the outer side, a stepping motor connected to a ball screw is arranged in the hollow cavity, a ball nut is sleeved on the ball screw and is fixed to the support, the support and a fine adjustment gear rotate, the fine adjustment gear is engaged with a fine adjustment rack and is equipped with a fine adjustment hand wheel in the middle, the shell slides with the support and is fixed with the fine adjustment rack, a light source, a condenser, a slit, an objective lens group, a reticle and an ocular lens are arranged on the shell, a reading roller is arranged below the ocular lens, a turntable is connected to the platform, a workbench adjusting rack and a rotating hand rod, a measuring workbench rotates with a workbench adjusting gear, and a workbench adjusting hand wheel is arranged in the middle of the workbench adjusting gear and is meshed with the workbench adjusting rack.According to the invention, a blind area of height adjustment is avoided, the measuring workbench can be circumferentially adjusted, and the application range is wider.

Description

technical field [0001] The invention relates to an optical section microscope, in particular to an optical section microscope for measuring the microscopic topography of the steel plate surface. Background technique [0002] Optical section microscope is an instrument for measuring the surface roughness of processed workpieces based on the principle of optical sectioning. It is widely used in surface measurement of engineering parts and training of laboratory experimental skills in colleges and universities. Nowadays, when measuring the microscopic topography of the steel plate surface, light-section microscopes are often used. However, when adjusting the height of the light-section microscopes currently used, most of them are carried out by plugging in. For example, the patent application number is CN201320853409.9 , a Chinese utility model patent titled "Multifunctional Integrated Optical Sectioning Microscope", there is a height adjustment blind spot when it is used, and ...
