High-precision automatic polishing machine

Abstract

The invention discloses a high-precision automatic polishing machine. The high-precision automatic polishing machine comprises a material loading support seat, polishing support seats, a plurality ofmechanical arms, polishing heads and material conveying fixtures, wherein the polishing heads and the material conveying fixtures are installed and connected to tail end joint points of the mechanicalarms correspondingly, the material loading support seat and the polishing support seats are arranged in the circumferential direction of the mechanical arms correspondingly, the material conveying fixtures are suction cup mechanisms, the suction cup mechanisms comprise installation plates and a plurality of suction cups connected to the corresponding installation plates, each polishing head comprises an outer shell body, an inner shell body, a core body and a rotating head, the inner shell body is located inside the corresponding outer shell body, the core body is rotatably arranged inside the corresponding inner shell body, the rotating head is installed and connected to the corresponding core body, each polishing head is further provided with an air pipe installation seat installed to the corresponding outer shell body, and each air pipe installation seat comprises an air inlet portion and an air outlet portion. According to the high-precision automatic polishing machine, by means of the arrangements of rubber rings, sealing pad rings and pad pieces, the sealing effect of the lower portions of the polishing heads is enhanced layer by layer, water vapor and liquid can be effectively prevented from entering the shell bodies, components inside the shell bodies are protected, and the service life of the high-precision automatic polishing machine is prolonged.

Description

technical field [0001] The invention relates to a high-precision automatic polishing machine, which belongs to the technical field of precision parts processing 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.
