Automatic metal surface processing device

Abstract

The invention discloses an automatic metal surface processing device which comprises a feeding support, a polishing support, a plurality of mechanical arms, a polishing head an a transporting clamp, wherein the polishing head an the transporting clamp are in erection joint with the tail nodes of the mechanical arms; the feeding support and the polishing support are arranged in the circumferentialdirection of the mechanical arms; the feeding support comprises a bracket and a feeding table mounted on the bracket; the polishing head further comprises an inner shell, an outer shell, a core body and a rotary head; the inner shell is in the outer shell; the core body is rotatably arranged in the inner shell; and the central axis of the outer wall cylindrical surface of the inner shell and the central axis of the inner wall cylindrical surface of the inner shell are in parallel and do not coincide. According to the automatic metal surface processing device, the inner and outer shells are combined with the core body, the structure is skillful, the air enters the inner shell through a first cavity to blow a driving blade, the driving blade drives the core body to rotate, the air is then discharged out through a second cavity, and the core body rotates to drive the rotary head to rotate so as to realize automatic polishing. The automatic metal surface processing device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to an automatic metal surface processing device, which belongs to the technical field of processing precision parts of electronic products. Background technique [0002] At present, most of the appearance structural parts / accessories of mobile phones and laptops on the market are made of metal materials. The forming of metal materials mainly includes aluminum extrusion, die-casting, forging and other methods. No matter which forming method is used, CNC machining centers are required for processing after forming. Due to the existence of poor appearance such as knife marks and scratches in the CNC machining process, a series of appearance retreatments such as passivation, grinding and polishing, spraying, and anodic oxidation must be carried out on the workpiece. However, on each workpiece, the area that needs to be polished is often only in a local area, because the grinding device cannot identify the local area that needs to be po...

AI Technical Summary

Problems solved by technology

However, on each workpiece, the area that needs to be polished is often only in a local area, because the grinding device cannot identify the local area that needs to be polished, and the local grinding can only be achieved through comprehensive grinding, which is time-consuming and labor-intensive, and the processing efficiency is low.
