Polishing machine of 3D printed product

Abstract

The invention discloses a polishing machine of a 3D printed product. The polishing machine comprises a grinding mechanism and a drive mechanism connected with the grinding mechanism. The drive mechanism is connected with a handheld handle. A dust collection shell is arranged below the grinding mechanism. The drive mechanism comprises a motor protection shell and a variable frequency motor. The variable frequency motor is connected with a drive rotating rod. The tail end of the drive rotating rod is provided with a cavity clamping cylinder. The grinding mechanism comprises a polishing disk protection shell and grinding disks. The grinding disks include a coarse grinding disk and a fine grinding disk which are fixed together through a powerful bonding layer. The center position of the coarsegrinding disk and the center position of the fine grinding disk are both provided with fixing grooves. The fixing grooves are internally provided with grabbing rods. The drive rotating rod penetratesthe polishing disk protection shell, and the outer side of the grabbing rod is sleeved with the cavity clamping cylinder. By means of the scheme, the maximum polishing rate can be increased, the changing frequency of the grinding disks is reduced, and the using convenience is further improved; and the protection shell is convenient to demount, the maintaining and polishing efficiency of the polishing machine is improved, and therefore the polishing working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing product maintenance, in particular to a polishing machine for 3D printing products. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacturing of some products. There are already parts printed using this technology. . The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others.

AI Technical Summary

Problems solved by technology

[0007] (1) The polishing disc cannot be replaced. A polishing machine can only use one polishing disc. If a coarse grinding disc is used, the grinding accuracy will be affected and new damage will easily occur. If a fine grinding disc is used, the grinding time will be prolonged and the efficiency of grinding and polishing will be affected. Constantly changing the polishing machine during polishing, wasting a lot of time;

[0008] (2) The protective shell of the polishing disc is fixed and cannot be disassembled. When the protective shell is damaged, a new shell cannot be reinstalled, which poses a safety hazard to human health
