An index plate of a micro balance

Abstract

The invention discloses a dial of a micro-balance. The dial of the micro-balance comprises a metal cover, wherein the metal cover is composed of a metal cone, a metal cylinder and a metal disk in a connected mode, and the metal cone, the metal cylinder and the metal disk are concentric circles. The lower round face of the metal disk and the upper round face of a metal handle are connected with each other and are concentric circles. The metal handle is a reverse cone. A round groove is dug upwards in the lower round face of the metal disk. The inner wall face of the groove is matched with the circular conical face of the metal handle, and the inner wall face of the groove and the circular conical face of the metal handle overlap. A first round hole is dug downwards in the middle of the upper face of the metal cone. A second round hole, an upper conical hole, a third round hole and a lower conical hole are dug downwards in sequence, are concentric circles and are connected to form a through hole. A front threaded hole is drilled rearwards in the middle of the front arc-shaped face of the metal handle and is communicated with the third round hole. A left threaded hole is drilled rightwards in the middle of the left arc-shaped face of the metal handle and is communicated with the third round hole. A circle of half-sheet cylinder heads are evenly arranged around the metal cylinder on the edge of the upper round face of the metal disk, and the number of the half-sheet cylinder heads is 47. A circular conical face of the metal cone is evenly divided into 10 digital blocks.

Description

technical field [0001] The invention relates to an index plate of a micro balance, in particular to an important part of a high-grade precision balance for measuring and weighing trace substances. Background technique [0002] Usually, in various fields such as precision machinery, chemical industry, medicine, food, etc., it is necessary to measure and weigh the added or contained trace substances in order to understand the content and weight, which is conducive to improving the quality of the main product; and to achieve this purpose, It needs a micro balance to complete; most of the existing micro balances are imported, and the price is expensive; some of the domestic ones have large errors, are inconvenient to use, and fail to achieve the purpose; in the years of research and experiments, the company has innovated and manufactured a new type, practical It is a new type of micro balance with low cost, good quality and performance, and accurate measurement, which can be com...
