A 3D printer for additive and subtractive composite processing with grinding function

Abstract

The invention discloses a 3D printer with a polishing function and a composite processing of increasing and decreasing materials, which comprises a printer main body, a workbench, a swinging driving mechanism, a U-shaped frame, a connecting shaft, a moving groove, a second sliding block, a polishing mechanism, a sliding flat plate, a sliding plane and a limiting block. The lower end inside the printer main body is provided with the workbench. One side of the printer main body is provided with the swinging driving mechanism. A movable rod is driven by a second motor to rotate, so that a grinding wheel can rotate. According to the external dimension of the 3D printer, the second motor is driven by the telescopic movement of a second cylinder, so that the grinding wheel can move back and forth to grind the surface of the product. If the product has the radian, the force of a connecting rod is applied to the mounting plate through the connecting rod being driven by the telescopic motion ofa first cylinder, so that the mounting plate rotates around a first connecting seat and a sliding rod moves up and down to maintain the stability of the mounting plate structure. At this time, the grinding angle of the grinding wheel changes so as to grind the radian surface.

Description

Technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer with a polishing function for compound processing of increasing and decreasing materials. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of cumulative manufacturing technology, that is, a kind of machine of rapid prototyping technology. It is based on a digital model file and can be bonded with special wax materials, powdered metals or plastics. Material, three-dimensional objects are made by printing layers of adhesive materials. After the 3D printer prints the object, the surface layer of the object will form layer-by-layer connection marks or burrs left during the printing process, making the product appearance more effective Therefore, it is necessary to design a 3D printer with polishing function for adding and subtracting composite processing. Summary of the invention [0003] The purpose of the present inventi...

[0002] 3D printer, also known as three-dimensional printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond Materials, by printing layers of adhesive materials to manufacture three-dimensional objects, because after the 3D printer prints the object, the surface layer of the object will form layer-by-layer connection marks or burrs left during the printing process, making the appearance of the product more effective. Poor, therefore, it is necessary to design a 3D printer for additive and subtractive composite processing with a grinding function
