Background technology
Present 3D printer has XYZ types to beat 3D printer, its main feature is that the transmission of three axis is independent mutually, three axis respectively by
Three stepper motor independent controls, the reprap series increased income, Ultimaker, the Makebot Series machines increased income all are adopted
With XYZ type structures.XYZ is clear in structure simple, three axis of independent control so that mechanical stability against short circuit, printing precision and print speed
The high performance of comparison can be maintained.But when printing curve, it is necessary to which two spindle motors of XY link, it is fixed to cause in this case
Position error.
CoreXY types 3D printer uses XY linkage structures（In addition to Z axis, XY axis is all that two stepper motor coordinations are matched somebody with somebody
Conjunction carries out transmission positioning）So that 3D printer transmission efficiency higher can design the 3D printer of more low-power consumption.The 3D is beaten
Two feed belts of print machine appear to be intersecting, are that on two planar, one on another in fact.And X,
Two stepper motors are then mounted on the balladeur train of Y-direction movement so that the movement of balladeur train is more accurate and stable.But it is printing
During curve, the movement of two step motor controls still cannot obtain the revolving body of high quality.
Present 3D printer also has parallel arm（Also known as triangular form）, this structure is by the Lausanne, SUI Institute of Technology earliest
(EPFL) Reymond Clavel professors are in the trigonometric expression structure of the invention eighties in last century.Earliest trigonometric expression parallel manipulator
Arm is mainly used to design a kind of robot that can operate slight small item body with speed quickly.Trigonometric expression parallel mechanical arm is that one kind passes through
A series of parallelogram of interconnections carrys out the mechanical structure of movement of the control targe in X, Y, Z axis.But due to triangle
Coordinate transformation be algorithm using interpolation, camber line carries out interpolating analogue with the small straight line of many items and approaches, the number of small line segment
Amount directly affects the effect of printing, causes the lack of resolution printing precision of triangle is opposite to be declined slightly.And parallel arm 3D is beaten
The installation of print machine is complicated, debugging is difficult, the not easily-disassembled replacement of part.
The content of the invention
The problem of positioning accuracy is limited in print rotated body part for existing 3D printing technique, the present invention to be solved
The technical issues of be just to provide it is a kind of based on cylindrical coordinates transmission positioning 3D printer, it can improve revolving parts 3D printing into
The precision of type obtains the revolving body of high quality.
The technical problems to be solved by the invention are that technical solution in this way is realized, it includes pedestal, disk machine
Structure, vertical adjustment mechanism, horizontal adjusting mechanism and nozzle mechanism, rotating disk mechanism can be rotatably arranged on pedestal, vertical to adjust
Mechanism is placed in chassis side, and horizontal adjusting mechanism is transversely mounted on vertical adjustment mechanism, and nozzle mechanism is slidably mounted to this
On horizontal adjusting mechanism, a print space is formed between nozzle mechanism and rotating disk mechanism.
The solution have the advantages that：
The rotating disk mechanism of the present invention is capable of providing rotary freedom, flat adjustment mechanism is capable of providing horizontal degree of freedom, vertical adjustment
Mechanism is capable of providing height free end, and when print rotated body, nozzle is only moved in short transverse, and coordinates the rotating disk mechanism
Circular motion can obtain the better printing precision of camber line, and be experienced with splendid visual aesthetic.
The present invention is print rotated body, disk covers type objects and provides new thinking, and can greatly simplify print path
Positioning accuracy is improved in footpath, can expand to pottery mud and draw the necks such as embryo, cream shaping, concrete 3D printing, biomaterial rapid shaping
Domain is driven the application range of positioning 3D printer to expand this based on cylindrical coordinates.
The structure of the present invention is simple, at low cost, easy to use, and the general standard room of machinery may be employed, this causes zero
Part cost of manufacture more, and is easy to safety, maintenance, replacement etc., to reduce the 3D printer based on cylindrical coordinates transmission positioning
Use cost and maintenance cost.
It is an advantage of the invention that：The molding precision of revolving parts 3D printing is improved, the revolving body of high quality can be obtained.
