Sample grinding device

Abstract

The invention discloses a sample grinding device. The device comprises two H-shaped supports and a grinding disc, two cross beams are arranged at the upper ends of the two H-shaped supports, a slidingcomponent is erected between the two cross beams, and can move left and right, a downward pressing component is arranged on the sliding component, an elastic clamping part is arranged at the lower end of the downward pressing component, a sample to be ground is arranged in the elastic clamping part, a first sliding rod, a second sliding rod, a third sliding rod and a fourth sliding rod are horizontally arranged between the two H-shaped supports in a front and back manner, connecting parts are horizontally arranged between the first sliding rod and the sample to be ground, between the second sliding rod and the sample to be ground, between the third sliding rod and the sample to be ground and between the fourth sliding rod and the sample to be ground, the grinding disc is arranged betweenthe sample to be ground, and a grinding sample is arranged on the grinding disc; the problem of excessive grinding or inclined grinding in the manual sample grinding process can be solved, accuracy ofdielectric parameter testing can be improved, standardization and normalizing of the sample testing process tested by dielectric parameters of the sample to be tested of the loose structure can be achieved, and the damage to the sample in the sample grinding process can be avoided.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding materials, in particular to a sample grinding device. Background technique [0002] With the rapid entry of electronic products into people's lives, electromagnetic wave pollution follows, so the research and development of electromagnetic shielding materials is particularly important. Dielectric properties refer to the properties of storing and dissipating electrostatic energy under the action of an electric field, usually expressed by dielectric constant and dielectric loss. The dielectric properties of materials directly characterize the electromagnetic shielding performance of materials. Therefore, for The study of the dielectric properties of materials is the key to solve the problem of electromagnetic shielding. [0003] The dielectric properties refer to the response characteristics of the bound charges in the substance molecules to the applied electric field, usually mai...
