Capacitance variable control surface flatness detection device for new material

Abstract

The utility model relates to the technical field of new materials, in particular to a capacitance variable control surface flatness detection device for new materials. The device comprises a shell, uniformly distributed positive electrodes are fixedly connected on the inner side of the bottom of the shell, and negative electrodes corresponding to the positive electrodes are fixedly connected on the outer side of the bottom wall of the shell. According to the capacitance variable control surface flatness detection device for the new material, a dielectric plate and a magnetic repulsion device are matched for use, the contraction length of the dielectric plate is controlled by utilizing the surface of the new material, and the magnetic force of the magnetic repulsion device is further changed; when the surface of the new material is flat, the magnetic block is still positioned in the middle of the movable groove and points to the middle of the standard disc; if the surface of the new material is uneven, the magnetic block deviates when being repelled by the magnetic repelling devices with different magnetic forces, and the finger block also deviates from the middle part of the standard disc so that the effect of capacitance variable hole detection is achieved, the flatness of the surface of the new material is visually obtained, the operation is simple and visual and the detection efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a surface smoothness detection device for new materials with capacitive variable control. Background technique [0002] New materials refer to newly developed or developing structural materials with excellent properties and functional materials with special properties. Structural materials mainly use their mechanical properties such as strength, toughness, hardness, and elasticity. [0003] After some new materials are produced, it is necessary to measure their flatness for later use. The current flatness measurement is mostly through visual inspection, or random measurement with simple tools, so most of the measured results are not accurate enough. New materials that are not smooth enough are put into use, which will eventually bring unpredictable consequences, and visual inspection is time-consuming and labor-intensive, and the efficiency is relatively low.
