Automatic machining mechanism for notebook computer shell

Abstract

The invention discloses an automatic machining mechanism for a notebook computer shell. The automatic machining mechanism comprises feeding supports, polishing supports, a plurality of mechanical arms, a polishing head and a material-conveying clamp, the polishing head and the material-conveying clamp are mounted at and connected with end joints of the mechanical arms correspondingly, and the feeding supports and the polishing supports are arranged in the circumferential directions of the mechanical arms correspondingly; and a rubber ring is mounted at the tail end of a lower shaft part in a sleeving mode, a bearing is arranged in a shell part of a rotating shell, a sealing washer is arranged on the lower part of the bearing, an annular gasket is arranged on the lower part of the sealing washer, a washer is mounted on a lower shaft part of a core body in a sleeving mode and embedded into a through hole in the upper surface of a lower bearing seat, and the upper surface of the washer ishigher than the upper surface of the lower bearing seat. According to the automatic machining mechanism for the notebook computer shell, the situation that a rotating head is stuck when downward-pressing force is excessively large can be prevented, flexible rotation of the rotating head is ensured, through eccentric arrangement that the rotating head and the core body for driving the rotating head to rotate have different axes, a polishing trajectory is not left in the polishing process, and the elaborate degree of polishing is increased.

Description

technical field [0001] The invention relates to an automatic processing mechanism for a notebook case, and 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 t...

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.
