Steel plate unevenness measuring device and method

Abstract

The invention relates to the technical field of intelligent measurement, and discloses a steel plate unevenness measuring device and method, and the device comprises a platform, a conductive leveling instrument, and a support. The platform is provided with a conductive plane used for placing a steel plate, the support can slide relative to the conductive plane, the conductive leveling instrument is movably installed on the support and arranged above the conductive plane, and the conductive leveling instrument can move in the direction perpendicular to the conductive plane. The extension direction of the conductive leveling instrument is parallel to the conductive plane, a conductive circuit is connected between the conductive plane and the conductive leveling instrument, and a power supply and an indicator are connected in series on the conductive circuit. A circuit is formed among the conductive plane, the steel plate, the conductive leveling instrument and the indicator, the conductive leveling instrument is in contact with the steel plate to control on and off of the circuit, so that the highest protruding point of the steel plate is determined, the method is more scientific and accurate compared with visual inspection, convenience and rapidness are achieved, and the accurate unevenness of the steel plate can be obtained.

Description

technical field [0001] The invention relates to the technical field of intelligent measurement, in particular to a steel plate roughness measurement device and method. Background technique [0002] The flatness of the steel plate means that the steel plate is placed freely on the platform, and no pressure is applied except the weight of the steel plate itself, and the maximum distance between the lower surface of the steel plate and the platform is measured (such as Figure 5 shown). [0003] At present, there is a big gap between the existing steel plate roughness measurement tools at home and abroad. Scanning measurement technology is generally used abroad. This method has high accuracy, but the corresponding supporting equipment is complex and expensive. Generally, visual inspection or steel ruler and tape measure are used to measure, put the steel plate on the platform, and measure the raised height of the steel plate several times at different positions of the steel pla...

Problems solved by technology

[0003] At present, there is a large gap between the existing steel plate roughness measurement tools at home and abroad. Foreign countries generally use scanning measurement technology. This method has high accuracy, but the corresponding supporting equipment is complicated and expensive; Generally, it is measured visually or with a steel ruler and a tape measure. Put the steel plate on the platform, and measure the raised height of the steel plate multiple times at different positions of the steel plate to compare the value. This method needs to move the tape measure multiple times and read. Operation Inconvenient and difficult to obtain accurate measurement data
