Embodiment 1
As depicted in figs. 1 and 2, a kind of work platforms tiltable 3D printer in the present embodiment, the triangular prism shaped framework being mainly made up of base 1 and support 13, nozzle structure 14, shower nozzle motion, work platforms 12 and work platforms motion form；
The quantity of base 1 is two, lays respectively at framework top and bottom；Shower nozzle motion includes sliding block 8, halts block 9, Timing Belt 10, feed rod 11, support bar 15, clamp block 16, motor 17, top shoe 19 and shower nozzle platform 20.Described feed rod 11 is six, is individually fixed between two bases 1；
As shown in Figure 1 and Figure 4, clamp block 16 and the quantity halting block 9 are three, lay respectively at the upper and lower of every side of triangular prism shaped framework；The clamp block 16 of every side is fixed on top shoe 19, halts block 9 and is fixed on sliding block 8, and sliding block 8 is fixed on feed rod 11；Described motor 17 quantity is three, it is both secured on the base 1 on framework top, motor 17 is fixed on the base 1 of base of frame by motor fixing plate 18, and described motor fixing plate 18 is separately fixed on the base 1 on framework top corresponding to three summits of triangular prism shaped framework.Timing Belt 10 two ends of every side are all connected with motor 17 and halt block 9, motor 17 drives top shoe 19 and clamp block 16 to move on feed rod by Timing Belt 10, shower nozzle platform 20 is connected with three clamp blocks 16 respectively by six roots of sensation support bar 15, and in six support bars 12, every two compose in parallel three bar parallel institutions.
As it is shown on figure 3, work platforms motion is mainly made up of the lower platform 3 on the base 1 being fixed on base of frame and three electric pushrods 5, three electric pushrod 5 two ends are connected with work platforms 12 and lower platform 3 with Hooke's hinge 4 by spherical hinge structure 7 respectively；The spherical hinge structure connecting electric pushrod 5 is arranged according to equilateral triangle；Work platforms 12 is supported by work platforms support bar 6, and work platforms support bar 6 two ends all connect work platforms 12 and lower platform 3 center by spherical hinge structure 7.
Work platforms 12, spherical hinge 7, be uniformly distributed installation electric pushrod 5, worktable support bar 6, Hooke's hinge 4 collectively constitute work platforms motion.Rotating as it is shown on figure 3, work platforms motion uses parallel institution to realize work platforms 12 around A, B axle, its operation principle is: work platforms 12 links via spherical hinge 7 with three equally distributed electric pushrods 5 as parallel institution moving platform, work platforms；Electric pushrod 5 is linked by Hooke's hinge 4 with the lower platform 3 of the silent flatform as parallel-connection structure, thus forms 3-RPS parallel institution.Understood this parallel institution by screw theory there is Z-direction rectilinear movement and rotate 3 degree of freedom around X, Y-axis.Additionally, be also to use parallel institution to realize in the motion considering shower nozzle, and moving along X, Y, Z can be realized.But the motor control between work platforms, shower nozzle is open loop, i.e. independent control, so, control error for suppression, in this parallel institution, connect the upper lower platform of parallel-connection structure by fixed length work platforms support bar 6 thus limit the degree of freedom of Z-direction rectilinear movement.The motion in tri-directions of X, Y, Z of nozzle structure is realized jointly by support bar 15, clamp block 16, top shoe 19, Timing Belt 10 and nozzle structure, form parallel institution between each component as the main body of this part, make shower nozzle have X, Y, Z tri-degree of freedom of moving of direction.The action principle of these parts is: 3D printer frame is as the silent flatform of this parallel institution, and symmetrical top shoe and feed rod 11, support bar 15 are linked with shower nozzle platform 20 by spherical hinge by three as the side chain of this parallel institution.The moving sets that wherein feed rod and top shoe 19 are formed is as the active drive joint of this parallel institution, controlled the position of top shoe via the clamp block connected firmly mutually with top shoe by step motor drive Timing Belt, thus the positional information of top shoe needed for obtaining shower nozzle spatial attitude by means of the resolving of 3-PPP parallel institution normal solution, resolve under planning shower nozzle spatial attitude by 3-PPP parallel institution is inverse, thus obtain and control parameter accordingly.After being controlled parameter accordingly, the motor 17 being sent order three side chains of control by control system drives Timing Belt 10, Timing Belt 10 drives the motion of the moving sets being made up of top shoe 19 and feed rod 11 via the clamp block 16 being fixedly connected with top shoe 19, moving sets is as the active drive joint in this parallel institution, when it has appointment position, it will determine the specific pose of shower nozzle platform thus meet motion requirement.Halting block 9 and sliding block 8 to be connected by bolt and be connected, sliding block 9 is fixed on feed rod 11 by side by bolt, halts block 9 for limiting and regulate the stroke of workbench and shower nozzle, and is machined with projection to prevent Timing Belt 10 from skidding off.
