Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the present invention, in the premise of not conflicting conflict
Under can be with combination of interactions.
Referring to Figures 1 and 2, this is the embodiment of the present invention, specifically:
A kind of 3D printer of printable camber line, including rack, rack are equipped with outer driving motor, further include that can determine around vertical
The upper ring gear 1 of axis rotation, the outer driving gear 7 being connect with the shaft of outer driving motor for being located at 1 side of ring gear, upper ring gear 1
On be fixedly connected with arc drive shaft 31, arc drive shaft 31 intersects with the dead axle, above arc drive shaft 31 be equipped with can side-to-side movement
The traversing axis 41 extended along the longitudinal direction, arc drive shaft 31 be equipped with can be along the lower company that the extending direction of arc drive shaft 31 moves
Block 51 is connect, traversing axis 41 is equipped with the upper link block 52 that can be moved along the extending direction of traversing axis 41, lower connecting block 51 and upper company
It connects block 52 to be connected with vertical shaft, arc drive shaft 31, traversing axis 41 are rack gear, and lower connecting block 51 is equipped with lower driving electricity
Machine, the shaft of lower driving motor are equipped with the lower driving gear 311 engaged with arc drive shaft 31, and upper link block 52 is equipped with upper drive
Dynamic motor, the shaft of upper driving motor are equipped with the upper driving gear 411 engaged with traversing axis 41, and the outer peripheral surface of upper ring gear 1 is set
There is turning gear, outer driving gear 7 is connect with upper 1 external toothing of ring gear, and the lower surface of lower connecting block 51 is equipped with print head.Allow outer driving
Gear rotation, so that ring gear be allowed to rotate, such arc drive shaft will be around fixed-axis rotation, to drive print head in upper ring gear
The arc-shaped movement of progress in ring, and the radius of the arc of lower driving gear adjustable printhead movement, upper driving gear and cross
The cooperation for moving axis can drive print head progress all around to move, to realize the printing of the feature of polygon.Thus give
Computer system is provided using polar hardware supported, realizes the printing of camber line, straight line.
Lower driving motor, upper driving motor, outer driving motor are servo motor；
Its control method is such that
It when needing printhead prints straight line in the front-back direction, makes traversing axis 41 static, allows the torque of lower driving motor to be zero, allow
Upper driving motor output walking torque, allows outer driving motor to export compensating torque, so that lower connecting block 51 be allowed to transport along traversing axis 41
It is dynamic；
When needing the straight line of printhead prints left and right directions, traversing axis 41 is allowed to move downward or move right, makes lower driving electric
The torque of machine is zero, allows driving motor output walking torque, allows outer driving motor output compensating torque, to allow lower connecting block
51 move along traversing axis 41；
When needing printhead prints using the movement on dead axle as the circular arc in the center of circle, the torque of lower driving motor is allowed to be zero, allowed outer
Driving motor output walking torque, allows driving motor to export compensating torque, to allow lower connecting block 51 around fixed-axis rotation；
When needing the printhead prints center of circle to be located at the circular arc of dead axle side, lower driving motor/upper driving motor torque is allowed to be
Zero, it accordingly allows driving motor/lower driving motor to export compensating torque, allows outer driving motor to export walking torque, to allow
The track of lower connecting block 51 is arc-shaped；
Due to special construction of the invention, lower connecting block can be allowed to walk by arc track, so avoiding out to the utmost
There are apparent corner angle in the curved surfaces of existing model.
Output walking torque is greater than compensating torque, thus print head activity can be allowed smooth, such control method can be kept away
Exempt from arc drive shaft 31, traversing axis 41 occur it is stuck.
In order to make upper ring gear rotation smooth, the lower section of upper ring gear 1 is equipped with fixed ring 2, sets between fixed ring 2 and upper ring gear 1
There is thrust bearing 5, fixed ring 2 is fixedly connected with rack, and upper ring gear is fixedly connected with the upside bearing circle of thrust bearing, fixed ring
It is fixedly connected with the downside bearing race of thrust bearing.
Upper link block, lower connecting block, print head shake during the work time in order to prevent, arc drive shaft 31, traversing
The longitudinal cross-section semicircular in shape of axis 41.
Better embodiment of the invention is illustrated above, but the present invention is not limited to the embodiment,
Those skilled in the art can also make various equivalent modifications or replacement on the premise of without prejudice to spirit of the invention, this
Equivalent variation or replacement are all included in the scope defined by the claims of the present application a bit.
