Self-adaptive polishing device for furniture special-shaped part

Abstract

The invention provides a self-adaptive polishing device for furniture special-shaped parts, and belongs to the technical field of furniture machining equipment. Comprising a rack, a rotatable abrasive belt framework, a workpiece clamp and a translation feeding mechanism, the rotatable abrasive belt framework is fixedly arranged at one end of the rack, the rotatable abrasive belt framework comprises a rotating cylinder, a mounting cylinder rotationally connected to the outside of the rotating cylinder and a plurality of abrasive belt mounting discs arranged in the rotating cylinder, and the mounting cylinder is fixed to the rack; an air cavity is formed between the rotating barrel and the mounting barrel, the abrasive belt mounting disc comprises a hollow barrel-shaped body, a positioning ring is arranged on the outer side face of the middle of the body, a plurality of air inlet holes are evenly formed in the portion, on one side of the positioning ring, of the body in the circumferential direction, an abrasive belt inserting groove is formed between every two adjacent air inlet holes, and a flexible strip-shaped grinding belt is inserted into each abrasive belt inserting groove. A pressing seat is arranged on the body; a vent hole communicated with the air cavity and the air inlet hole is formed in the circumferential surface of the rotating cylinder; and the rotating cylinder is driven by a driving motor. The special-shaped part polishing device has the advantages of being capable of automatically polishing special-shaped parts and the like.

AI Technical Summary

Problems solved by technology

[0002] After the rough processing of wooden furniture components or metal parts of furniture, it needs to be polished to make the surface smoother. When using equipment for processing, generally only flat surfaces or standard parts can be polished, and special-shaped parts are generally Using manual work, low efficiency, high labor costs, uniform product performance to control

[0003] In addition, in the prior art, whether it is mechanized polishing or manual work, the contact strength between the polishing belt (or sandpaper) and the polishing surface is achieved by directly or indirectly controlling the pressing force between the grinding wheel and the workpiece. Since the abrasive belt (or sandpaper) wears very quickly, the pressing force applied to the grinding wheel cannot be adjusted according to the degree of wear of the abrasive belt (or sandpaper) during mechanical polishing, and the construction experience of the operator is very dependent on manual polishing; As we all know, the wear speed of the abrasive belt (or sandpaper) is directly related to the pressing strength. Mechanical polishing and manual polishing also have the situation that the pressing force is too large to accelerate the wear of the abrasive belt (or sandpaper)

[0004] Furthermore, the wear of the abrasive belt (or sandpaper) has a greater relationship with its frictional heat generation, and the effective heat dissipation in the polishing process has a positive effect on maintaining the longer service life of the abrasive belt (or sandpaper); Or sandpaper) is polished by friction between the granular medium on the grinding surface and the workpiece. During the grinding process, a large amount of crumb dust is indispensable, and these crumb dust will remain in the concave part of the abrasive belt (or sandpaper). The grinding effect of the abrasive belt (or sandpaper) has adverse effects, which is also one of the ways in which the abrasive belt (or sandpaper) is worn, especially when polishing wooden materials, the concave part of the abrasive belt (or sandpaper) is covered with wood powder The filling speed is very fast, coupled with the high temperature during the grinding process, the wood chips are carbonized and accumulated in the concave part of the abrasive belt (or sandpaper), so that the original uneven grinding surface of the abrasive belt (or sandpaper) becomes smooth and smooth. loss of grinding function

[0005] To sum up, there are many defects in the existing grinding and polishing methods. Whether it is difficult to mechanically polish special-shaped parts, or the abrasive belt (or sandpaper) wears quickly, the existing methods are difficult to effectively overcome.
