Mobile phone rear cover machining and fixing device

Abstract

The invention relates to the field of mobile phone part machining, in particular to a mobile phone rear cover machining and fixing device. The device comprises a base, observation openings are formed in the two sides of the base, and an upper pressing plate is electrically and slidably connected to the base; a side fixing block is arranged at one side of the base, a plurality of lower sliding grooves are formed in the bottom of the base, and the lower pressing blocks are slidably connected in the lower sliding grooves; air discs are arranged on the upper end faces of the lower pressing blocks, a machining tooth groove channel is formed in an upper pressing plate, and a rotating shaft is arranged in the machining tooth groove channel; the upper end of the rotating shaft is fixedly connected with the output end of a first motor, the rotating shaft is fixedly connected with a gear meshed with the machining tooth groove channel in the machining tooth groove channel, and the bottom of the rotating shaft is fixedly connected with a machining plate base. A plurality of first hydraulic cavities are formed in the upper pressing plate, an upper pressing block is slidably connected in each first hydraulic cavity, and a first spring is arranged between the upper pressing block and the first hydraulic cavity, so that rear covers of different specifications can be fixed, meanwhile, the rear covers can be fixed in multiple directions, and the situation that a machining face is bent due to the force generated during machining, is avoided.

Description

technical field [0001] The invention relates to the field of mobile phone parts processing, in particular to a mobile phone back cover processing and fixing device. Background technique [0002] Mobile phone, the full name of mobile phone or wireless phone, usually called a mobile phone, was originally just a communication tool, and it was commonly known as "Big Brother" in the early days. It is a portable phone terminal that can be used in a wide range; in 1958, Soviet engineers Leonid Kuprijanovich invented the ЛК-1 mobile phone. In 1973, American Motorola engineer Martin Cooper invented the world's first commercial mobile phone. After going through the 2G era and the 3G era, it has developed to the 4G era so far, and the 5G era has followed closely behind, and 5G commercial use has appeared in China; [0003] In the composition of the mobile phone, the back cover of the mobile phone is in contact with people, and the quality of processing affects people's perception of t...

AI Technical Summary

Problems solved by technology

[0004] 1. When processing the back cover of the mobile phone, since the side of the back cover is a curved part, it is difficult to maintain the fixed state of the side when fixing it;

[0005] 2. There is pressure on the side during the processing of the back cover of the mobile phone, which will make the processing surface tilt, thereby reducing the processing accuracy and processing quality;

[0006] 3. There are many specifications of the back cover of the mobile phone, and it is difficult to fix the back cover of different specifications
