Parallel arm mechanism 3D printer shell and printer

Abstract

The invention provides an outer shell of a parallel arm mechanism 3D printing machine. The outer shell comprises an outer shell main body, wherein a mounting cavity used for mounting a printing machine main body is arranged inside the outer shell main body; and an upper opening and a lower opening which correspond to each other and communicate with the mounting cavity are formed in the outer shell main body. The printing machine comprises the printing machine outer shell and the printing machine main body arranged inside the outer shell main body. According to the outer shell of the parallel arm mechanism 3D printing machine and the 3D printing machine provided by the invention, the production mode of machinery is changed, and the large-scale production can be achieved; the problems that a traditional parallel arm mechanism 3D printing machine is difficult to assemble and maintain, internal mechanisms of the machinery are exposed, and the printing machine is liable to deform are solved; the outer shell main body adopts a reuleaux triangle mechanism, and chamfers on the two sides are combined, so that the mechanism of the entire printing machine is compact; internal machines can be located through utilizing the self structure of the outer shell, and the quick production is facilitated; and the printing machine outer shell has return difference elimination, deformation elimination, resonance elimination and shaking elimination functions.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a shell of a parallel arm mechanism 3D printer and a printer. Background technique [0002] Existing parallel arm structure Parallel arm mechanism 3D printer support structure is complex, for the upper and lower triangles and three vertical columns to support and fix corners, large-scale mass production is time-consuming and labor-intensive, usually as a low-end DIY model for customers to assemble by themselves , After assembly, a lot of work such as positioning, debugging, fixing and repeated tightening of screws and nuts is required to make the machine reach balance and stability. [0003] Because the column is driven by the inertia generated by the rapid movement of the print head to drive the entire frame to swing laterally, the printer will swing back and forth laterally when pulling back the consumables, and the two will also generate strong resonance. Due to the...
