Description

A kind of rapid prototyping machine
Technical field
The utility model relates to a kind of rapid prototyping machine.
Background technology
The rapid prototyping machine adopts the principle of three axis numerically controlled machine to work.Under the control of computer, shower nozzle can move along the direction of 3 axles.Heat-fusible materials (ABS, nylon or wax) is sprayed by the rear extruding of heater fusing, and be piled into an aspect.Then second aspect being used the same method builds, and with previous aspect clinkering together.Pile up so layer by layer, obtain a 3D solid.No matter rectangular co-ordinate mechanism rapidform machine is that cross section profile or inner scanning track are straightway, and namely when the processing cross section, the circular motion track of shower nozzle straightway commonly used replaces.Like this when the circular workpiece of processing, the not high problem of accuracy after will occurring processing.
The utility model content
The purpose of this utility model provides a kind of rapid prototyping machine that is applicable to process round piece.
To achieve these goals, by the following technical solutions: a kind of rapid prototyping machine, described prototype comprises workbench, the bottom of workbench is provided with the first motor, be connected with the first ball screw on the first rotating shaft of the first motor, be provided with through hole on the workbench, be provided with the nut of the first ball screw in the through hole, rotation along with the first rotating shaft, workbench can move up and down, it is characterized in that: described workbench side is provided with vertical bracing frame, the second rotating shaft of the bottom of bracing frame and the second motor joins, the top of bracing frame is connected with the fixed disk parallel with horizontal plane, and the central authorities of fixed disk are provided with the 4th rotating shaft by the 4th driven by motor, and the bottom of the 4th rotating shaft is connected with fixed mount, be provided with the 3rd motor on the fixed mount, the 3rd rotating shaft of the 3rd motor links to each other with the second ball screw, and the nut of the second ball screw links to each other with hollow transverse bar, and the front portion of transverse bar is provided with nozzle.
Also be provided with the cavity volume that holds heat-fusible materials on the described transverse bar, the cavity volume outlet links to each other with the entrance at nozzle rear portion.
The utility model is simple in structure, and the shower nozzle movement locus can be realized circular motion easily, need not multi-shaft interlockedly, and for other curves, but the polar coordinate representation of binding curve need not complicated algorithm.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model.
Among the figure, 1 is the first motor, and 2 is the second motor, and 3 is bracing frame, and 4 is fixed disk, and 5 is the 4th motor, and 6 is the 3rd motor, and 7 is fixed mount, and 8 is transverse bar, and 9 is cavity volume, and 10 is nozzle, and 11 is sample, and 12 is workbench.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As depicted in figs. 1 and 2, a kind of rapid prototyping machine, prototype comprises workbench 12, the bottom of workbench 12 is provided with the first motor 1, be connected with the first ball screw on the first rotating shaft of the first motor, be provided with through hole on the workbench, be provided with the nut of the first ball screw in the through hole, rotation along with the first driven by motor the first rotating shaft, workbench 12 can move up and down, and workbench 12 sides are provided with vertical bracing frame 3, and the second rotating shaft of the bottom of bracing frame 3 and the second motor 2 fixes, under the rotation of the second motor, bracing frame can rotate;
The top of bracing frame is connected with the fixed disk parallel with horizontal plane 4, the central authorities of fixed disk 4 are provided with the 4th rotating shaft that drives by the 4th motor 5, the bottom of the 4th rotating shaft is connected with fixed mount 7, be provided with the 3rd motor 6 on the fixed mount, the 3rd rotating shaft of the 3rd motor links to each other with the second ball screw, the nut of the second ball screw links to each other with transverse bar 8, the front portion of transverse bar 8 is provided with nozzle 10, also be provided with the cavity volume 9 that holds heat-fusible materials on the transverse bar, the cavity volume outlet links to each other with the entrance at nozzle 10 rear portions.
During use, the oscilaltion of the first Electric Machine Control workbench, Quality control 11 moves at the z direction of principal axis, if the sample that needs to form has circular cross-section, then the 3rd Electric Machine Control the second ball screw rotation, so that transverse bar is flexible or prolongation, then the 4th Electric Machine Control transverse bar is rotated as the center of circle take the 4th rotating shaft of the 4th motor, and the heat-fusible materials of shower nozzle ejection namely can form a circular wall like this.If need to finish other shape, only need the rotation of the second driven by motor fixed disk, the length variations of transverse bar can be finished simultaneously.
