Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the understanding of the present disclosure will be better and more comprehensive.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. ...

Abstract

The invention relates to a hole drilling method for a middle frame. The method is used for drilling a basic hole in a middle frame, the basic hole is used for communicating an inner cavity in the middle frame with the outside of the middle frame, the basic hole is machined by moving a cutter along a spiral line track, and the central axis of the spiral line track is parallel to the central axis ofthe basic hole. According to the method, the cutter moves along the spiral line track to machine and obtain the basic hole, the moving track is more coherent and complete, the polishing effect is fine, the inner wall of the basic hole is polished while the basic hole is machined, plastic burrs can be effectively removed, the burrs on the inner wall of the basic hole are easier to fall off, so that the machining quality of the inner wall of the side hole is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for opening holes in a middle frame. Background technique [0002] As a communication tool, mobile phones have been increasingly popular in people's lives, but with the continuous development of science and technology, the functions of mobile phones are becoming more and more powerful; Mobile phone manufacturers are scrambling to pursue the object, but the processing procedures of metal mobile phone casings are becoming more and more complicated. [0003] The middle frame of the mobile phone is generally provided with side holes, and these side holes include, for example, a sound output hole, a microphone hole, and the like. For some special openings, such as the microphone hole, since the sound cavity is usually connected therein, it is difficult to process these side holes and the processing quality of the inner wall of the side hole is poor.
