Six-axis 3D printer three-dimensional rotary table device for additive manufacturing of elastic wave metamaterial

Abstract

The invention discloses a six-axis 3D printer three-dimensional rotary table device for additive manufacturing of elastic wave metamaterials. The six-axis 3D printer three-dimensional rotary table device comprises a B-direction cradle type swing assembly, a C-direction objective table rotating assembly, an A-direction objective table swing assembly and an objective table. The B-direction cradle type swing assembly is fixed to a z-direction moving shaft of the 3D printer, and a rotating shaft of the B-direction cradle type swing assembly is perpendicular to the mounting plane. A U-shaped base is fixed in the middle of the B-direction cradle type swing assembly, a C-direction steering engine is assembled and driven in the base, a metal main steering wheel is assembled at the output end of the C-direction steering engine, and a rotating shaft of the C-direction steering engine is perpendicular to the upper plane of the U-shaped base. A threaded hole coaxial with the C-direction steering engine is formed in the bottom of the multifunctional support, and the C-direction objective table rotating assembly is connected with the A-direction objective table swinging assembly through threaded connection. An A-direction steering engine for driving the objective table to swing is fixed in the multifunctional support, the output end of the A-direction steering engine is in threaded connection with a metal main steering wheel, and the other end is connected with a bearing. The metal main steering wheel is in threaded connection with the U-shaped support to output transmission of the motor.

Description

technical field [0001] The invention relates to the technical field of three-dimensional turntable and additive manufacturing based on fused deposition modeling, in particular to a three-dimensional turntable device for a six-axis 3D printer used to manufacture mechanical metamaterials. Background technique [0002] The 3D printing technology based on Fused Deposition Modeling (Fused Deposition Modeling, FDM) is one of the traditional printing technologies in the field of 3D printing. Because the principle of layer-by-layer accumulation of printing materials in a molten state is simple and easy to implement, it is widely used by equipment developers. And users are welcome, it can be applied to print various complex physical models and handicrafts. [0003] This provides a new manufacturing idea for the field of mechanical metamaterials, which is seeking mass production methods. Mechanical metamaterials obtain extraordinary functions and physical properties that natural mate...

Problems solved by technology

[0005] Most of the existing multi-axis 3D printers use a multi-degree-of-freedom mechanical arm to achieve multi-axis control, such as a multi-axis 3D printer that connects the nozzle to the robotic arm. The defect of this device is that when the nozzle is not parallel to the vertical axis Z, The printing material is easy to flow in the molten state and affects the quality of the workpiece. Correspondingly, the manufacturing accuracy will also be greatly reduced

In addition, some colleges and universities in China have installed the printing workbench on the multi-degree-of-freedom robotic arm. This device has a better printing effect than the previous device from the perspective of liquid material flow, but the robotic arm itself is large and generally Saying that large robotic arms are less accurate than small robotic arms

This disadvantage is especially prominent when printing large workpieces with large 3D printers
