Abstract

The invention relates to a sheet steel surface roughness measuring table and method. The measuring table and method mainly solve the technical problem that in the prior art, the sheet steel surface roughness cannot be measured precisely. According to the technical scheme, the sheet steel surface roughness measuring table is composed of a master platform, a slave platform, a movable pressing plate, a fixing bolt, a tension bolt, a pressure rod and a guide rod assembly; the movable pressing plate is connected with the end of the working face side of the master platform and the end of the working face side of the slave platform in a fastening mode through the fixing bolt, one side face of the master platform is provided with a through hole and two blind holes, guide rods are fixedly arranged in the blind holes in the master platform, a part of the through hole in the master platform is provided with threads, the other part of the through hole is an unthreaded hole part, the pressure rod with the rod diameter being smaller than the diameter of the unthread hole is inserted into the unthreaded hole part, the side face of the slave platform is provided with a through hole matched with the guide rods in diameter, the tension bolt is connected to the thread part of the through hole in the master platform, the master platform is movably connected with the slave platform through the guide rods, and the height of the working face of the master platform is higher than that of the working face of the slave platform. The sheet steel surface roughness measuring table and method are mainly used for precise measuring of sheet steel and metal foil surface roughness.

Description

technical field [0001] The invention relates to a workbench and a measuring method for measuring the roughness of a steel plate, in particular to a measuring platform and a measuring method for measuring the surface roughness of a thin steel plate. Background technique [0002] In the prior art, there are two methods for measuring the surface roughness of thin steel sheets or metal foils: one is to curl thin steel sheets or metal foils into rolls with a diameter of 500-1500 mm, and place the roughness meter on the surface of the rolls Measurement; the second is to cut the thin steel plate into small pieces, place it on a special marble measuring platform, and place the roughness meter probe on the measuring platform to measure the surface roughness of the thin steel plate. Among the above two methods, the former is widely used in production and requires low measurement accuracy, while the latter is widely used in laboratories and requires high measurement accuracy. There ar...
