Abstract
The invention discloses a universal movement mechanism of a 3D printer. The universal movement mechanism of the 3D printer comprises a mechanism top, a mechanism bottom, a material extrusion device and a workbench. The workbench is arranged between the mechanism top and the mechanism bottom, and the material extrusion device is placed above the upper surface of the workbench. Three sets of universal rotating components and three sets of transmission components are further included, and the transmission components are sleeved with sliding blocks which can slide up and down. The three sets of transmission components are installed between the mechanism top and the mechanism bottom at intervals. The sliding blocks are connected with the material extrusion device through the universal rotating components and the material extrusion device. According to the universal movement mechanism of the 3D printer, only the Z-axis direction is reserved, by the aid of the scheme, the printing speed can be increased substantially, and moreover due to the fact that two axial movements are reduced, the problems of resonance and noise are solved.
Description
Technical field
The present invention relates to a kind of 3D printer, relate in particular to a kind of 3D printer universal movement mechanism.
Background technology
Along with the continuous progress of 3D printing technique, people have higher requirement to the function of 3D printer, performance and reliability.For desktop 3D printer, print fine degree in kind and also have many places that have much room for improvement.
Existing 3D printer, before printing, is to adopt traditional XYZ three-axis moving scheme, exists print speed slow, easily produces resonance noise large, the shortcoming that three-axis stabilization degree is poor, and the material object of printing has certain error, causes printing precision to decline.
And 3D printer is before printing, work top need to regulate its position.In adjusting operating platform, can cause the table top of workbench to tilt, not measure up.Therefore the material object printing on workbench is had to certain error, and such error is difficult to avoid, more easily precision in kind is printed in impact.
Summary of the invention
The object of the invention is to solve the problems of the prior art, provide that a kind of print speed is fast, noise is little, good stability and without the 3D printer universal movement mechanism of adjusting operating platform position.
Technical scheme of the present invention is: a kind of 3D printer universal movement mechanism, comprise mechanism top, mechanism bottom, extruded material device and workbench, described workbench sets up an organization between top and mechanism bottom, and described extruded material device is positioned at the top of worktable upper surface; Also comprise three groups of universal rotational parts and three groups of drive disk assemblies, on described drive disk assembly, be arranged with the slide block sliding up and down; Being arranged between mechanism top and mechanism bottom of described three groups of drive disk assembly intervals; Described slide block is connected with described extruded material device by universal rotational parts.
Described universal rotational parts comprise pair of links, are provided with first Universal-head integrated with it and the second Universal-head at the two ends of described connecting rod; Opposite side at described slide block and extruded material device offers respectively the first uncovered groove and the second uncovered groove; Described the first Universal-head is inserted in the first uncovered groove, and described the second Universal-head is inserted in the second uncovered groove and can realizes rotation.
Being arranged between mechanism top and mechanism bottom with positive triangle of described three groups of drive disk assembly equi-spaced apart.
Described drive disk assembly comprises driving motor, ball-screw and slide bar, and described driving motor is arranged at the top of ball-screw, and described ball-screw and slide bar are set up in parallel between mechanism top and mechanism bottom, and described slide block set is located on ball-screw and slide bar.
Described workbench is fixedly installed on mechanism bottom by several supporters.
Described supporter is three, is welded on the upper surface of mechanism bottom.
The bottom of described extruded material device is provided with material extruder head over against workbench place.
The present invention will replace existing 3D printer to press the mode that XYZ tri-axle schemes are printed, change to and on hardware, only have direction of motion of Z axis, the motion of XY direction is converted on Z axis, its essence is that extruder head is XY two axle movement, and mechanical arm only has direction of Z axis, such scheme can increase substantially print speed.And owing to having reduced by two axially-movables, thereby resonance and noise problem have been solved.
And the present invention is structurally with respect to the structure of other printer, workbench of the present invention is fixed, and extruder head can freely-movable in tri-directions of XYZ.The horizontal error that such motion mode has avoided adjusting operating platform or Long Gravity to produce causes the meticulous not problem even tilting of material object printing.

The specific embodiment
For technological means, technical characterictic, goal of the invention and the technique effect that the present invention is realized is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, for a kind of 3D printer universal movement of the present invention mechanism, comprise top 100, mechanism of mechanism bottom 200, extruded material device 300 and workbench 400, top 10He mechanism of mechanism of the present invention top 200 is all connected with the body of 3D printer, for this motion being fixedly mounted on to 3D printer.
Shown in figure 2, Fig. 3 and Fig. 4, the present invention also comprises 501,502,503 and three groups of drive disk assemblies 601,602,603 of three groups of universal rotational parts, on corresponding drive disk assembly 601,602,603, is all arranged with the slide block 701,702,703 sliding up and down; Being arranged between top 100He mechanism of mechanism bottom 200 of described three groups of drive disk assemblies 601,602,603 intervals; Being arranged between top 100He mechanism of mechanism bottom 200 with positive triangle of described three groups of drive disk assemblies, 601,602,603 equi-spaced apart.Slide block 701,702,703 is connected with described extruded material device 300 by universal rotational parts 501,502,503.
Drive disk assembly of the present invention comprises driving motor 604, ball-screw 605 and slide bar 606, certainly ball-screw 605 and the slide bar 606 in the present invention also can be replaced by guide rail, and slide block is arranged on guide rail, achieve the effect moving up and down, be not limited to a kind of sliding type of ball-screw.Driving motor 604 of the present invention is arranged at the top of ball-screw 605, and ball-screw 605 and slide bar 606 are set up in parallel between top 100He mechanism of mechanism bottom 200, and slide block set is located on ball-screw 605 and slide bar 606.
