An electronic ceramic inner hole processing crack prevention device

Abstract

The invention discloses an electronic ceramic inner hole processing crack prevention device, comprising an electronic ceramic body, an elastic roller, an upper cover body plate, a lower cover body plate, an elastic thin-walled connecting frame, a restricting long rod, and a compression spring; There will be an inner hole, a compression spring will be set outside the middle of the restricting rod, and elastic rollers will be provided outside the restricting rod, above and below the compression spring. The position of the inner hole restricts the connection between the top and bottom ends of the long rods respectively with the upper cover plate and the lower cover plate. There is an accommodation space between the upper cover plate, the lower cover plate and the elastic roller. The wall connecting frame is tightly fitted and clamped in the accommodating space by its transverse sectional surface, and the compression spring is in a compressed state at this time. The structure of the invention solves the problem that the electronic ceramic is easily cracked during the drilling operation of the light and thin electronic ceramic caused by the traditional fixture device.

Description

technical field [0001] The invention relates to the technical field of electronic ceramic equipment, in particular to an electronic ceramic inner hole processing crack prevention device. Background technique [0002] Electronic ceramics are widely used to make electronic functional components. They are essentially different from general power ceramics in chemical composition, microstructure and electromechanical properties. These differences are formed by a series of special technical requirements put forward by the electronic industry for electronic ceramics, the most important of which are high mechanical strength, high temperature and humidity resistance, radiation resistance, dielectric constant changes in a wide range, The tangent value of dielectric loss angle is small, and the temperature coefficient of capacitance can be adjusted. High electrical strength and insulation resistance, and excellent aging properties. [0003] Electronic ceramics can be widely used in e...

AI Technical Summary

Problems solved by technology

[0003] Electronic ceramics can be widely used in energy, household appliances, automobiles, etc., but because of its light and thin properties, it is easy to crack when drilling. In the traditional drilling process, the fixture can only cover the part of the ceramic. The vibrating force on the ceramic can only be borne through the area in contact with the fixture, which leads to the uneven distribution of the vibrating force on the ceramic as a whole, and the thin and thin ceramic is easy to crack, so the traditional fixture equipment cannot meet the drilling operation of the thin and light ceramic
