Example 1:
the invention designs a portable folding 3D printer, which is shown in a figure 1-4 and comprises a top frame 10, a bottom frame 5, an X-shaped vertical lifting structure inner arm 1, an outer arm 4, a slide rail 16, a slide block 15, a printing head 9, a printing platform, a lead screw 1, a 42 stepping motor 12, a transformer 13 and the like; the inner and outer arms of the X-shaped vertical lifting structure are respectively connected to a front end top plate connecting piece 8 through a convex shaft connecting piece 14, a rear end top plate connecting piece 7, a front end bottom plate connecting piece 6 and a rear end bottom plate connecting piece 3, the front end top plate connecting piece 8 and the front end bottom plate connecting piece 6 are respectively connected to X-axis moving plates and printing platform two sides on a slide rail, the X-axis moving plates and the printing platform two sides are carried on the slide rail through sliders, the rear end top plate connecting piece 7 is fixed to two sides of a top frame 10 and connected with a Z-axis moving plate 17, and the rear end bottom plate connecting piece 3 is fixed to two sides of a bottom frame 5.
The moving device of the printer is composed of a 42 stepping motor 12 for driving a lead screw 11, the lead screw 11 and a lead screw nut seat 18 which is positioned on the lead screw 11 and drives a Z-axis moving plate 17 of an outer arm of an X-shaped vertical lifting structure to move. The lead screw is connected to the lead screw nut seat through the lead screw nut. The inner arm and the outer arm are connected through the middle shaft 2, and driven by the Z-axis moving plate 17 to move synchronously through the sliding block on the sliding rail, and the printing head 9 is fixed on the X-axis moving plate and can freely move along the X-Y Z axis under driving.
The X-shaped vertical lifting structure comprises the following components: inner arm 1, outer arm 4, axis 2, protruding axle connecting piece 14, roof mounting 7, 8, bottom plate mounting 3, 6, slide rail 16, slider 15 have following advantage: (1) the rolling friction force is small, and the stability is good; (2) the contact area is large, and the elastic deformation is small; (3) the effective moving bodies are more, and high-rigidity and high-load movement is easy to realize; (4) the structure design is flexible, the installation and the use are convenient, and the service life is long; (5) small mechanical energy consumption, high precision, high speed and large bearing capacity.
The central shaft 2 of the X-shaped vertical lifting structure is used as a boundary, the end of the X-shaped vertical structure far away from the motor is connected with a sliding block 15 of a sliding rail 16 through a convex shaft fixing piece 14 and a connecting piece, the sliding rail 16 is fixedly connected with the corresponding positions of the top plate 10 and the bottom plate 5, and the end of the X-shaped vertical structure close to the motor is connected with the connecting piece directly fixed with the bottom plate 5 of the top plate 10 through the convex shaft fixing piece 14.
The screw rod driving module is used for driving the two groups of X-axis vertical lifting structures to move left and right synchronously far away from the motor end. In this embodiment, the screw driving module includes a screw 11, a stepping motor 42, a screw nut seat 18 and a Z-axis moving plate 17 fixed on the screw nut seat and connected to the X-axis vertical lifting structure. The 42 stepping motors are correspondingly and electrically connected with the stepping motor driver ports of the controller. Therefore, the left and right synchronous movement of the two groups of X-axis vertical lifting structures far away from the motor end can be realized only through one group of screw rod driving modules, and the synchronous effect is superior to that of other synchronous methods. Further, lead screw 11 of lead screw drive module sets up in the print platform below, like this between power and the circuit board, can avoid lead screw drive module to set up when, because lead screw drive module's weight leads to the printer problem that the side is inclined to one side and the focus is high. And meanwhile, the movement of the X-axis vertical lifting structure is stable.
