A 3d printer walking mechanism

Abstract

The invention discloses a walking mechanism for a 3D (three-dimensional) printer. The walking mechanism comprises a walking mechanism platform, a rotary disk, a rhombic telescopic frame, a spiral shaft and a sliding rail, wherein the walking mechanism platform is sleeved on the sliding rail and is in threaded connection with the spiral shaft; two ends of the spiral shaft are fixed between a top plate and a bottom plate of the printer through bearings; a gear (B) is arranged at the lower end of the spiral shaft and is driven to rotate by a stepping motor (C) which is arranged on the bottom plate; a circular disk is arranged at the upper end of the rotary disk; the middle of the rotary disk is connected with a rotary shaft; a gear (A) is arranged at the lower end of the rotary shaft; the rotary disk is arranged on the walking mechanism platform; a stepping motor (A) is arranged on the lower part of the walking mechanism platform; a gear at a rotary head of the stepping motor (A) is meshed with the gear (A) at the lower end of the rotary shaft; the rhombic telescopic frame is arranged on the rotary disk and mainly comprises four light shafts. The walking mechanism for the 3D printer is simple in structure and convenient to use, and a 3D space in the printing process of the 3D printer can be accurately positioned by controlling the change of the radius, the rotary angle and the height.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a traveling mechanism of a 3D printer. Background technique [0002] With the advancement of science and technology, 3D printer technology has gradually matured. The mainstream 3D printing method uses repeated stacking of thin layers of hot-melt materials, namely the Fused Filament Deposition Method (FDM) to cast models. The three-dimensional model is made by computer software and sent to the printer in the form of slices, and then the computer controls the traveling mechanism to carry the nozzle, ejects the material according to the contour position information, prints layer by layer, solidifies, and finally forms a three-dimensional model. The traveling mechanism is 3D printer technology important components in. [0003] At present, the traveling mechanism of most 3D printers adopts the XY-axis Cartesian coordinate system. The stepping motor on the X-axis and Y-axis drives...

AI Technical Summary

Problems solved by technology

[0003] At present, the traveling mechanism of most 3D printers adopts the XY-axis Cartesian coordinate system. The stepping motor on the X-axis and Y-axis drives the traveling mechanism to realize free movement in the plane. The change of the Z-axis direction is realized by controlling the lifting of the printing platform. This structure often requires more slide rails and shafts, which makes the internal structure of the 3D printer bulky and complicated.
