Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0029] The method for grinding the mirror surface of the USB slot panel of the mobile phone includes the following steps:

[0030] (1) Stamping and forming mobile phone USB slot components;

[0031] (2) Polishing the USB slot panel of the mobile phone to grind out a surface with a mirror effect;

[0032] (2.1) Place the USB slot panel of the mobile phone to be ground on a flat grinding disc or jig. The grinding disc rotates counterclockwise, and the jig drives the grinding workpiece to rotate clockwise. The 2000# alumina solution between the workpiece and the grinding disc is used for relative running friction. Through the rotation of the grinding disc and the pressure applied to the grinding workpiece, the surface of the USB slot panel of the mobile phone is cut with 2000# alumina sand grains;

[0033] (2.2) Add 8000# alumina solution when rotating, and use 800...

Abstract

The invention relates to a mirror polishing method of a mobile phone USB slot panel and a mobile phone USB slot component. The polishing method comprises the following steps: (1), punching to form the mobile phone USB slot component, (2), grinding the mobile phone USB slot panel to form a surface with mirror effect, (2.1), laying the ground mobile phone USB slot panel on a smooth grinding disc or a jig, ensuring that the grinding disc rotates anticlockwise and the jig drives a grinding work piece to rotate clockwise, adding rough grinding composition during rotation, performing relative operation friction through the rough grinding composition permeating the part between the grinding work piece and the grinding disc, and cutting the surface of the mobile phone USB slot panel through sand grains of the rough grinding composition, and (2.2), adding finish grinding composition, and repairing the surface of the mobile phone USB slot panel through sand grains of the finish grinding composition. The mobile phone USB slot component comprises the closed and annular slot panel matched with the shape of a USB plug, a slot wall vertically extending along the inner side of the slot panel, and a plurality of arm braces respectively, symmetrically and convexly arranged on the edge of the slot wall.

Description

technical field [0001] The invention relates to a mirror grinding method for a mobile phone USB slot panel and a mobile phone USB slot component. Background technique [0002] CN201020294752.0 announced "a mobile phone with a USB interface". Its purpose is to provide a USB plug connected to the mobile phone body through the connecting seat as a whole, so as to avoid poor contact of the mobile phone caused by stretching the USB cable. At the same time, the fixed shaft in the connection seat is a rectangular column, which can ensure that the USB connector is in a fastened state with the mobile phone body when rotating, and improves the stability of the USB use of the mobile phone. It has a USB interface. mobile phone. The technical solution: the mobile phone with a USB interface includes a mobile phone body (1), a mobile phone main circuit board installed in the mobile phone body (1), and a card slot (3) is also arranged on the mobile phone body (1) , the card slot (3) is p...
