Printing bottom plate fixing device and 3D printing workbench

Abstract

The invention discloses a printing bottom plate fixing device and a 3D printing workbench. The printing bottom plate fixing device comprises a base frame, a lifting platform, a first buckling mechanism and a second buckling mechanism; a bottom plate mounting area is arranged on the upper surface of the lifting platform, the structure of the first buckling mechanism and the structure of the secondbuckling mechanism are in bilateral symmetry, the first buckling mechanism comprises a first lever assembly, a first stop block, a first hook body, a second stop block and a third stop block; and thefirst lever assembly comprises a first transverse rod, a first hinged support and a first elastic component. When the lifting platform ascends, two hook heads can be away from each other and move upwards, a printing bottom plate can be placed in the bottom plate mounting area, then the lifting platform descends, the two hook heads get close to each other and move downwards, and therefore the printing bottom plate can be fixed, and otherwise the printing bottom plate can be taken down, the printing bottom plate is easy and convenient to mount or dismount, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a printing bottom plate fixing device and a 3D printing workbench. Background technique [0002] For 3D printers using fused deposition manufacturing technology, such as wax-type 3D printers, when printing, first install the printing base plate on the 3D printer, and then print. After printing, print the base plate and the wax pattern printed on the printing base plate. Take it off from the 3D printer for subsequent processing. [0003] When the printing base plate is installed on the worktable of the printer, it is necessary to ensure that the printing base plate fits the workbench surface; the existing 3D printers generally set four internal thread holes on the four corners of the workbench, and the corresponding holes on the printing base plate Set a through hole at the position, and then fix the printing base plate on the workbench through bolts. Although this method can...

[0003] When the printing base plate is installed on the worktable of the printer, it is necessary to ensure that the printing base plate fits the workbench surface; the existing 3D printers generally set four internal thread holes on the four corners of the workbench, and the corresponding holes on the printing base plate Set a through hole at the position, and then fix the printing base plate on the workbench with bolts. Although this method can ensure that the print base plate fits the work surface, it is time-consuming and laborious to install and disassemble, and the efficiency is low.
