A kind of 3D printer
The utility model relates to printing technique field, particularly relates to a kind of 3D printer.
3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is based on a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufacture three-dimensional object by the jointing material printed from level to level.Present stage, three-dimensional printer was used to manufacture a product.The mode successively printed carrys out the technology of constructed object.The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be created product from level to level according to program.
The form of the stacking thin layer of 3D printer has varied.3D printer and the maximum difference of conventional printer are that " ink " that it uses is out and out raw material, and the form of stacking thin layer has varied, can be used for the medium wide variety printed, from various plastics to metal, pottery and rubber-like material.Some printer can also in conjunction with different medium, makes that one, the object printed is hard and other end is soft.
Existing 3D printer generally adopts stepper motor to drive screw rod to realize the motion of printing head in X, Y, Z-direction, motion path is straight line, and when printing the parts of circular or arcuate structure, programming is complicated, and step is many, printing effect is low, is difficult to the demand meeting processing.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of 3D printer.
The utility model is achieved through the following technical solutions:
A kind of 3D printer, comprise line slideway, printing head, described line slideway is provided with slide block, described upper end of slide block is provided with the first circulator, and described first circulator is connected with first connecting rod one end, and the described first connecting rod other end is connected with the second circulator, described second circulator is connected with second connecting rod, described second connecting rod one end is provided with the 3rd circulator, and described 3rd circulator is connected with third connecting rod one end, and described third connecting rod one end is connected with printing head.
As optimal technical scheme of the present utility model, described line slideway longitudinal cross-section shape is convex shape structure.
As optimal technical scheme of the present utility model, described first circulator axis be Y-direction arrange, the second circulator axis be X to layout, the 3rd circulator axis be Z-direction layout.
As optimal technical scheme of the present utility model, the L-shaped structure of described second connecting rod.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, it is many that the utility model realizes the printing head free degree under the acting in conjunction of line slideway, the first circulator, the second circulator and the 3rd circulator, simultaneously few for the parts printing step of complexity, working (machining) efficiency is high, meets the demand of people to low cost.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of 3D printer, comprise line slideway 1, printing head 9, described line slideway 1 is provided with slide block 2, and wherein said line slideway 1 longitudinal cross-section shape is convex shape structure, can realize the rectilinear movement of printing equipment like this.Described slide block 2 upper end is provided with the first circulator 3, described first circulator 3 is connected with first connecting rod 4 one end, described first connecting rod 4 other end is connected with the second circulator 5, described second circulator 5 is connected with second connecting rod 6, the L-shaped structure of wherein said second connecting rod 6, is convenient to realize the horizontally disposed of the second circulator 5 like this.
Described second connecting rod 6 one end is provided with the 3rd circulator 7, described 3rd circulator 7 is connected with third connecting rod 8 one end, described third connecting rod 8 one end is connected with printing head 9, described first circulator 3 axis is that Y-direction is arranged, second circulator 5 axis be X to layout, the 3rd circulator 7 axis be Z-direction arrange.Under the acting in conjunction of line slideway 1, first circulator 3, second circulator 5 and the 3rd circulator 7, realize printing head 9 free degree many, simultaneously few for the parts printing step of complexity, working (machining) efficiency is high, meets the demand of people to low cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
