Print base plate fixing device and 3D printing workbench

Abstract

The invention discloses a printing bottom plate fixing device and a 3D printing workbench provided therewith. The printing bottom plate fixing device includes a base frame, a lifting platform, a first fastening mechanism and a second fastening mechanism, and the upper surface of the lifting platform is provided with a bottom plate In the installation area, the structure of the first fastening mechanism and the structure of the second fastening mechanism are left-right symmetrical, and the first fastening mechanism includes the first lever assembly, the first stopper, the first hook body, the second stopper and the third stopper block, the first lever assembly includes a first cross bar, a first hinge seat and a first elastic member. When the lifting platform rises upwards, the two hooks will move away from each other and move upwards. The printing base can be placed on the base installation area, and then the lifting platform is lowered, and the two hooks are close to each other and moving downwards, which completes the fixing of the printing base. , on the contrary, you can remove the printing bottom plate; it is simple and convenient to install or remove the printing bottom plate, saving time and effort.

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...
