The pendulum is affected by the gravity of the earth's center and is suspended in a frictionless state. Electrodes are set on both sides of the pendulum and the capacitance is equal when the gaps are the same. If the level is affected by the workpiece to be measured, the capacitance will be different when the two gaps change by different distances, resulting in different angles. Vernier calipers have the characteristics of simple structure, easy use, medium accuracy and large measuring range. They can be used to measure the inner diameter, outer diameter, length, width, thickness, depth and hole spacing of parts. They have a wide range of applications and are universal measuring tools.
[0021] After the steel bars 2 are installed and positioned, this kind of common quality problem is greatly improved. Because the steel plate 303 is digitally cut, all the cutting grooves 304 positioning holes are in the same position as the drawing. All the steel bars 2 are in the middle of the installation holes 102, which effectively improves the gripping effect of the grouting material and ensures the overall quality after the project is completed. Digital cutting uses a laser cutting machine for cutting. The laser emitted from the laser is focused into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Laser cutting replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, no limitation on cutting patterns, automatic typesetting to save materials, smooth incisions, low processing costs, etc., ensuring the accuracy of 303 steel plates.
