Problems solved by technology

[0003] Existing 3D printers are generally driven by a stepper motor connected with a screw rod, and some also use double screw rods to make the Z-axis platform rise, or some add smooth guide rods to guide the Z-axis platform to rise steadily , down, the main purpose is to allow the Z-axis platform to rise and fall along the vertical direction, but it is impossible to set the two screw rods, the screw rod and the guide rod in absolute vertical parallelism. Too many guide rods and screw rods will not only fail to better ensure the vertical rise and fall of the Z-axis platform, but will cause the Z-axis platform to rise to a certain height due to the gap between the screw rods and between the screw rods and the guide rods. The parts are parallel to each other and get stuck, resulting in that the rising speed of the Z-axis at this position does not meet the expected requirements, and the quality of the printed product is problematic and inaccurate. The existing technology needs to be improved.

Abstract

The invention provides a Z-axis guiding device for a 3 D printer. The Z-axis guiding device for the 3 D printer comprises a connecting plate, a guiding shaft and a plurality of fixing shafts. The guiding shaft is provided with a screw hole and is fixedly arranged on the connecting plate. The connecting plate and the guiding shaft are coaxially provided with a screw hole with the same hole diameter as the hole diameter of the screw hole of the guiding shaft. The fixing shafts are provided with screw holes, so that the guiding device is fixed to a Z-axis platform through screws. Multiple arc-shaped holes are formed in the positions, surrounding the guiding shaft, of the connecting plate. The Z-axis guiding device for the 3 D printer is applied to vertical guiding of the Z-axis platform and is installed on the Z-axis platform. A screw rod penetrates through the guiding device, and when the screw rod drives the platform to go up, the platform goes up smoothly and does not get stuck. By using the guiding device, 3 D printing can be made to be more accurate.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, in particular to a Z-axis guide device for 3D printers. Background technique [0002] 3D printing technology is a rapid prototyping technology that uses meltable materials and is based on digital files to generate products layer by layer. When printing, the print head of the printer moves through the XYZ axis, and the XY axis The print head moves in the horizontal plane, and the Z-axis platform makes the print head rise and fall in the vertical direction to print layer by layer. The structure of the existing 3D printers is getting simpler and more powerful. [0003] Existing 3D printers are generally driven by a stepper motor connected with a screw rod, and some also use double screw rods to make the Z-axis platform rise, or some add smooth guide rods to guide the Z-axis platform to rise steadily , down, the main purpose is to allow the Z-axis platform to rise and fall along the vertical dir...
