Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
As shown in Figs. 1-5, the rotatable 3D printing device of workbench of the invention, including,
Be translatable mobile mechanism 1, to carry extruder head and the extruder head 3 is driven to be translatable;Such as the translation of X-axis and Y-axis,
Rotary table 2, flexible support arm 21 and working plate 20 are driven including three, and the support arm is uniform It is distributed and is rotatably connected with one end and working plate, the other end and the swingable connection of support plate 22, that is, three along working plate Circumferential 120 degree of uniformly distributed support arms move synchronously the translation for realizing working plate, as Z axis is mobile;It is moved when three support arm differences Realize the rotation of working plate.Such as around the overturning of X-axis and Y-axis.
The present invention by 5 axis Kinematic Decompositions of 3D printing be extruder head translation planar and the lifting of working plate and The movement overturn around X-axis and Y, may be implemented to rotate around X-axis and Y-axis ± 45 degree.Movement by controlling motor can meet work The various positions requirement of platform, realize the printing of Arbitrary 3 D three-dimensional model, very good solution alias and cantilever design The problem of, reduce the use of backing material, while can realize that composite material is printed along any machine direction.
Preferably, it is the globality for improving equipment, further includes pedestal, the translation mobile mechanism is fixed on pedestal top Portion, the support plate 21 of the rotary table are fixedly connected with the pedestal bottom.The rack is square framework type knot Structure is fixedly connected by angled piece by industrial aluminum profile and is constituted, and light weight, stress is strong, makes full use of the industrial aluminum profile, can be with Save space.
Specifically, the translation mobile mechanism includes, X is to driving portion comprising two are separately positioned on pedestal two The X of side is slidably disposed on two Xs of the X on guide rod to carrying block 13 by linear bearing respectively to guide rod 11, with And the driving X is to the X for carrying block and being moved to guide rod along X to driving motor;Y-direction driving portion comprising two both ends with it is described X to the Y-direction guide rod 12 that is fixedly connected of block is carried, be slidably disposed on the Y-direction carrier by linear bearing, and and its In an X to block is carried be fixedly connected with the Y-direction driving motor to drive the Y-direction carrier to move along Y-direction guide rod, described squeezes Lift one's head and is arranged on the Y-direction carrier.
Wherein, X is realized respectively by synchronous belt to driving motor and Y-direction driving motor and is driven, meanwhile, X is real to motor The X of existing two sides further includes Synchronous Transmission bar, a synchronous belt is being respectively set by drive rod both ends to the synchronizing moving for carrying block Dynamic and two synchronous pulleys, the synchronous driving of two sides, are effectively ensured traveling comfort.
Specifically, the support arm 21 and workbench 20 pass through the swingable connection of shaft, i.e. composition spherical pair, upper end It is rotatably connected by oscillating bearing and the working plate.Wherein, have in three shafts one and X to it is perpendicular or parallel with Realize the simplification of control.
In specific implementation, as one of embodiment, the support arm 21 includes with the support plate by turning The support rod of axis connection, the line slide rail 211 being fixedly connected with the support frame are fixedly connected and drive with the support rod Spindle motor 213 and one end that dynamic feed screw nut is moved along the line slide rail and the feed screw nut 214 is fixed connects Connect one end and connecting rod 212 that the working plate is rotatably connected, i.e., the feed screw nut be fixed at it is described On the matched sliding block of line slide rail, the axial direction of spindle motor is axial parallel with line slide rail, is by the movement of spindle motor The movement of connecting rod can be achieved, nationality is to realize the flexible of support arm.
Preferably, the connecting rod and hollow tube, the lead screw of the spindle motor can matchingly be inserted into the connection It is interior and be freely rotated.Volume exclusion can be effectively saved in this way, and effective print space is provided.The present embodiment uses spindle motor and cunning Rail slide block device controls three support arms and stretches, can be with save the cost while more compact structure is convenient for control.
As the second embodiment of support arm of the present invention specific implementation, the support arm includes passing through with the support plate The support rod of shaft connection, the line slide rail being fixedly connected with the support frame are fixedly connected and drive with the support rod The telescope motor and one end that movable slider is moved along the line slide rail are fixedly connected with one end and described with the sliding block The connecting rod that working plate is rotatably connected.
It realizes that the flexible of support arm is equally able to achieve above-mentioned control by synchronous belt using telescope motor, and passes through synchronization Band is sequentially connected, and space requirement degree is low, is arranged more convenient.
The control method of the rotatable 3D printing device of workbench of the present invention, including,
X respectively drives extruder head X to driving motor and Y-direction driving motor and is translatable to Y-direction,
The translation of three support arm synchronization telescope driving working plate Z-directions,
One of support arm elongation in three support arms, synchronous shorten of other two support arm are realized around X-axis or Y-axis turn It is dynamic, meanwhile, realizing the compound motion that can also go up and down with Z axis while rotation around X-axis or Y-axis.
It when realizing rotation, such as turns about the X axis, the axis of rotation is rotated by the center around platform. By the elongation of one of support arm, the contraction of other two above-mentioned support arm realizes that is, three support arms will act.It beats During print, the decline of Z-direction workbench is needed to cooperate while rotation, specific falling head is according to the shape of model Depending on shape.In specific control process, because print head realizes the movement of X-axis and Y-axis, relative ease is controlled, therefore print head moves Dynamic track needs the track for cooperating platform to move to realize that five-axle linkage prints.Three arm support working platforms can only realize one Mobile and two rotations, in print procedure, will also be combined with the movement of the X-axis and Y-axis of extruder head, to avoid interference and ask Topic.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications Also it should be regarded as protection scope of the present invention.
