Problems solved by technology

[0002] At present, the positioning mechanism of traditional 3D printers is an XYZ series mechanism, that is, three linear guide rails are parallel to the X, Y, and Z axes respectively. The printer controls the position of the printing nozzle through the linear motion of the three-axis guide rails, and the printing materials are stacked layer by layer along the Z axis direction. Forming a space model, the forming range of the printed part is limited by the length of the 3-axis guide rail, and the extrusion feeding mechanism of the traditional 3D printer is mostly integrated with the nozzle, resulting in large motion inertia of the system, low positioning accuracy, slow positioning speed, and low printing efficiency

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The present invention is based on the 3D printing system of the 6-PSS parallel mechanism, such as figure 1 As shown, it includes a top plate 1 and a bottom plate 2 parallel to each other, and the top plate 1 and the bottom plate 2 are connected by six guide rails 3, such as figure 2 As shown, a ball screw a4 is provided along the inner axis of each guide rail 3, and a servo motor and a reducer matching with the ball screw a4 are also arranged in each guide rail 2, and a slide is sleeved on the ball screw a4. The block 7 and the slider 7 are movably connected to the upper platform 9 through the branch chain 8, and the lower surface of the upper platform 9 is fixed with a nozzle 10;

[0021] The base plate 2 is provided with a mobile platform 11 that moves along the X-axis or the Y-axis.

[0022] Such as figure 2 As shown, the mobil...

Abstract

The invention discloses a 3D printing system based on a 6-PSS parallel mechanism, which includes a top plate and a bottom plate parallel to each other, the top plate and the bottom plate are connected by a guide rail, a ball screw a is arranged along the inner axis of the guide rail, and the ball screw a is covered A slider is connected, and the slider is movably connected to an upper platform through a branch chain, and a nozzle is fixed on the lower surface of the upper platform; a mobile platform that moves along the X-axis or the Y-axis is arranged on the bottom plate. The overall size of the printed object of the printer can be increased, and the application range of the printer can be expanded, thereby improving the practicability and economical efficiency of the printer.

Description

technical field [0001] The invention belongs to the technical field of printers, and relates to a 3D printing system based on a 6-PSS parallel mechanism. Background technique [0002] At present, the positioning mechanism of traditional 3D printers is an XYZ series mechanism, that is, three linear guide rails are parallel to the X, Y, and Z axes respectively. The printer controls the position of the printing nozzle through the linear motion of the three-axis guide rails, and the printing materials are stacked layer by layer along the Z axis direction. Forming a space model, the molding range of the printed part is limited by the length of the 3-axis guide rail, and most of the extrusion feeding mechanisms of traditional 3D printers are integrated with the nozzle, resulting in large motion inertia of the system, low positioning accuracy, slow positioning speed, and low printing efficiency. Contents of the invention [0003] The purpose of the present invention is to provide...
