Automatic leveling type 3D printer

Abstract

The invention belongs to the technical field of 3D printing, in particular to an automatic leveling type 3D printer. The automatic leveling type 3D printer comprises a printing box and a transmissionmechanism installed inside the printing box, wherein the transmission mechanism is in transmission connection with a machine head, the bottom surface of the interior of the printing box is provided with a placing mechanism corresponding to the machine head, and the placing mechanism comprises a fixing plate and a mounting plate rotating on the top surface of the fixing plate. In use, the transmission mechanism drives the machine head to move, then, a pushing mechanism pushes a contact head on an electromagnet to descend through a supporting rod, and to contact with a magnetic attraction metalring, the electromagnet is electrified, then a stepping motor is started, the mounting plate and a placing plate above the mounting plate rotate synchronously, due to the facts that the mounting plateand the placing plate are connected through a self-locking air spring, and a ball head connector is fixed to the top end of the self-locking air spring, the placing plate can float under the action of the contact head, the placing plate can be automatically aligned after the placing plate rotates 360 degrees, the printing precision of the machine head is guaranteed, and alignment is more accurate.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an automatic leveling 3D printer. Background technique [0002] 3D printers can not only print a complete building, but can even print the shape of any desired item for astronauts in a spaceship, but what 3D prints out is the model of the object, and cannot print out the function of the object. 3D printers are also known as Three-dimensional printer (3DP) is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic, etc. Layers of adhesive materials are used to manufacture three-dimensional objects. At this stage, 3D printers are used to manufacture products, and the technology of constructing objects is printed layer by layer. The principle of 3D printers is to put data and raw materials into 3D printers. The product will be built layer by...

Problems solved by technology

[0003] The Chinese patent with the publication number CN105563828B discloses a self-leveling 3D printer, which can automatically adjust the level of the working platform, greatly saves labor energy, and can reduce the rate of defective printing. However, the gears have a certain pitch, so it is impossible to realize stepless adjustment, and the adjustment range is limited, resulting in low leveling accuracy of the working platform, which cannot meet the requirements of high-precision 3D printers.
