Automatic grinding machine used for grinding metal shell of USB interface

Abstract

The invention provides an automatic grinding machine used for grinding a metal shell of a USB interface. The automatic grinding machine comprises a machine case which is internally equipped with a PLC automatic control system and a rotary workbench, wherein a supporting panel is mounted at the outer side of the rotary workbench in parallel; four product positioning devices, two perpendicular grinding devices and loading mechanical hands, which are arranged on the upper end surface of the rotary workbench, are fixedly mounted on the supporting panel; a vibrating disc used for automatically loading is arranged beside the machine case; and a quantitative feeding mechanism is arranged at one side of the discharge hole of the vibrating disc. The automatic grinding machine realizes automatic positioning and grinding for the metal shell of the USB interface, so that grinding auxiliary time is greatly reduced, heavy job of clamping workpieces during large-scale production is reduced, and clamping and processing for the workpieces can be improved, and therefore, the automatic grinding machine has the advantages of reducing labor intensity of workers, improving production efficiency, improving processing quality and the like; and moreover, the production period of the metal shell of the USB interface is shortened, so that production benefits of the enterprises are improved, and economic level of workers is improved.

AI Technical Summary

Problems solved by technology

[0003] The surface roughness of the metal appearance of the commonly used mobile phone USB interface is required to be 0.2um. Due to the relatively small surface roughness and height tolerance requirements of the product, it is time-consuming and unstable to use traditional grinding.

For example, the traditional grinding machine needs manual clamping and machine operation, the CPK value of the same batch of parts cannot be guaranteed, the process will be unstable, it is not suitable for mass production, and it also increases the labor intensity of employees.

Traditional grinding machines also require a large number of employees to clean and unload the plates, which not only increases the cost of employees but also wastes time and consumables

In the process of processing, it is necessary to solve the problems of height, roughness and clamping, and the traditional grinding equipment is not suitable for processing
