Device for automatically enlarging grinding area during grinding of information terminal shell

Abstract

The invention relates to the technical field of information terminals, and discloses a device for automatically enlarging the grinding area during grinding of an information terminal shell. The device comprises a shell, a rotating shaft is movably connected to the upper end of the inner wall of the shell, a protective shell is fixedly connected to the lower end of the rotating shaft, an extension spring is movably connected into the protective shell, the lower end of the extension spring is fixedly connected with a guide block, the lower end of the guide block is movably connected with an extension rod, the lower end of the extension rod is movably connected with a moving plate, and the lower end of the moving plate is fixedly connected with a grinding stone. The guide block moves downwards, and when the guide block moves downwards, downward pulling force is applied to the extension spring, so that the extension spring is pulled to move downwards, the interior of the extension spring is stressed and compressed, elastic potential energy is gathered in the extension spring, preparation is made for resetting of the guide block, and the effect that by controlling the rotating speed of the rotating shaft, the grinding area is gradually enlarged is achieved.

Description

technical field [0001] The invention relates to the technical field of information terminals, in particular to a device for automatically enlarging the grinding area when grinding an information terminal shell. Background technique [0002] With the gradual development of society, people's living standards have been significantly improved, which has led to people's new research and development of modern technology. Among them, the equipment in the computer that inputs programs and data to the computer through communication facilities or receives computer output processing results It is an information terminal, which can effectively guarantee the output of information. [0003] However, at present, there are still defects that need to be overcome when grinding the shell of the information terminal. The grinding of the shell of the information terminal generally requires manual adjustments to the shell, so as to polish the designated position, but it often takes a lot of time,...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for automatically expanding the grinding area when grinding the shell of the information terminal, which can gradually expand the grinding area by controlling the rotation speed of the rotating shaft, and at the same time, when the work starts, automatically. The advantage of clamping the shell solves the problem that the grinding of the information terminal shell generally requires manual adjustment of the shell to polish the specified position, but it often takes a lot of time, which affects the processing efficiency. The casing shakes, which easily makes the grinding quality not up to standard
