Description
Technical field
The invention belongs to arm configuration 3D printer machine fields in parallel, are related to a kind of arm configuration 3D printer mechanical-assisted in parallel
Leveling structure especially in the case where automatic leveling is inaccurate and miniature deformation occurs for leveling state assist accurate
Leveling is solved in the accurate levelling problems of arm configuration 3D printer in parallel.
Background technology
Currently, generally believing that the 3D printer leveling of arm configuration in parallel is difficult in the industry, precision is relatively low, and principal contradiction is printing
Three starting point faces of horizontal plane and X, tri- column of Y, Z are difficult preferable parallel, now there are two types of more representational solutions：
1, using automatic leveling program, depth of parallelism analysis is done to bottom surface and three starting point faces using related algorithm, according to point
Analysis result does suitable rollback to ensure the depth of parallelism on two sides to relevant starting point.
Raft structures are used when 2, printing, and are spread raft structure initially several layers of, are made printing surface and starting point face using material
It is horizontal.
In above-mentioned two scheme, scheme one can not accomplish accurate leveling positioning, there was only the center faces Zhan Zong on circular platform
The place one of accumulated score of three can be considered smooth, the edges of land regions cannot perfect control platform at a distance from nozzle.Scheme
Second material is extremely expended, and molding model bottom surface is short-tempered and is difficult to clear up, and makes printout monnolithic case finish and beauty
Degree reduces.
In addition, the leveling status pole malleable of parallel arm 3D printer.In transporting moving process, clears up thermal head or take
It is no longer available that the leveling scheme debugged is taken hours before easily being caused because of micro-strain during drag, is needed
It will leveling again.And such case need to only finely tune only because caused by the miniature deformation of rack.But automatic leveling program
Since precision limits, it is difficult to be automatically finely adjusted to the situation.For the problem, some 3D printers need area of computer aided
Could complete leveling, it is unusable or not at one's side in computer, it may appear that can not leveling the problem of.
Invention content
Technical problems to be solved
In order to avoid the shortcomings of the prior art, the present invention proposes a kind of arm configuration 3D printer mechanical-assisted tune in parallel
Flat structure, by individually accurately controlling X, tri- column start position of Y, Z is to realize accurate leveling.
Technical solution
A kind of parallel connection arm configuration 3D printer mechanical-assisted leveling structure, it is characterised in that including adjusting screw 1, adjustment spiral shell
Mother 2, holder 3, spring 4, fixed corner fittings 5, frame section bar 6, limit switch fixed block 7 and limit switch 8；Fixed corner fittings 5 is 60
The triangular structure of degree, two frame connection framework proximate matters 6, holder 3 run through top one end of frame section bar 6, and adjusting screw 1 adjusts
The through-hole and spring 4 of 3 upper end of nut 2 and holder are pressed on frame section bar 6, and the lower end of holder 3 is limit switch fixed block
7, limit switch fixed block 7 is equipped with limit switch 8.
Advantageous effect
A kind of arm configuration 3D printer mechanical-assisted leveling structure in parallel proposed by the present invention, is not smart enough in automatic leveling
Auxiliary leveling is carried out in the case of really, by adjusting screw adjusting nut, the structural members such as spring and holder and dedicated corner fittings
Cooperation, finely tuning the start position of three axis of arm configuration 3D printer in parallel keeps it parallel with printing surface, to improve parallel arm knot
Structure 3D printer leveling precision, and can effectively avoid printing bottom surface injustice problem caused by miniature deformation.
It is advantageous in that compared with prior art：
1, the leveling precision of parallel arm 3D printer is largely improved.Coordinated by using nut-screw and is finely tuned, it is reachable
To the trimming precision of 0.01mm.
2, conveniently leveling.Using components such as springs in structure design, the automatic rollback in fine tuning is convenient accurate.
3, leveling is stablized, it is ensured that longer usage time.The structure will not cause unexpected displacement because colliding limit switch
Cause positioning inaccurate.Furthermore the leveling structure is fixed on machine upper end, and debugging is convenient, is not easy to touch because of modulus type.Once
Debugging, can keep for a long time.

Specific implementation mode
In conjunction with embodiment, attached drawing, the invention will be further described：
Embodiment includes adjusting screw 1, adjusting nut 2, holder 3, spring 4, fixed corner fittings 5, frame section bar 6, limits and open
Close fixed block 7 and limit switch 8；The triangular structure that fixed corner fittings 5 is 60 degree, two frame connection framework proximate matters 6, holder 3
Through top one end of frame section bar 6, the through-hole and spring 4 of 1 adjusting nut 2 of adjusting screw and 3 upper end of holder are pressed in frame
On proximate matter 6, the lower end of holder 3 is limit switch fixed block 7, and limit switch fixed block 7 is equipped with limit switch 8.
Leveling process：
1, according to structure shown in Fig. 2, this leveling structure is respectively mounted in tri- column of X, Y, Z：In arm configuration 3D printer in parallel
Tri- column of X, Y, Z on installation arm configuration 3D printer mechanical-assisted leveling structure in parallel, connect three parallel connections with frame section bar
Two frames of 5 triangular structure of fixation corner fittings of arm configuration 3D printer mechanical-assisted leveling structure are constituted vertical with X, Y, Z tri-
The vertical triangle projective planum structure of column；
2, the self-leveling arm-type 3D printer of parallel connection, operation automatic leveling program carry out first step coarse adjustment.If without certainly
Dynamic leveling procedure adjusts the actual height position of print space coordinate origin according to the specification of each producer so that is beaten in control
When printing head nozzle at print space coordinate origin (0,0,0), nozzle has a closer (such as 0.2mm away from printer bottom bracket
Or the thickness that stacks of two standard A4 printing papers) distance.
3, cylinder model is established by 3 d modeling software, cylindrical radius is the 80% of print space bottom surface radius, high
Degree is H mm, and embodiment selection is set as 1.The cylinder model file built up is exported with STL formats, and using Slice Software to output
Cylinder model file carry out slicing treatment, slicing parameter is：Thickness 0.2mm, line width are print head bore, temperature 190~210
DEG C, speed 50mm/s, no raft structures, no brim structures, bottom height h mm.Embodiment is selected as 0.2mm, enables hott bed,
Hott bed temperature is 70 DEG C, and the first floor does not enable fan.
4, be loaded into printing consumables, steps for importing 3. in complete slice file, start to print.
5, after the completion of printing, it is cooled to room temperature, record bottom cylindrical face is away from X, the nearest point of tri- column of Y, Z, and in cylinder
It is marked on bottom surface.Model is removed, the cylinder height at three points marked using miking is denoted as hx, hy, hz。
6, the deviation value of height at three points is calculated, formula is as follows：
Δi=H-hi
Wherein i=x, y, z.Unit mm.
7, X, the adjustment amount of tri- column start position of Y, Z are calculated：If the helical pitch of adjusting screw 1 is S, X, Y, tri- columns of Z
The adjustment amount ε of start positioni
εiUnit is rad.
8, according to calculating gained X, the corresponding adjustment amount ε of tri- column of Y, Zi, rotate X, the corresponding adjusting nut of tri- column of Y, Z
2, so that the movement that nut rises is denoted as just, if adjustment amount εiFor positive value, then the direction of rotating nuts should be such that nut rises, and limit is opened
Shut liter.The rotation angle of adjusting nut 2 is adjustment amount εiIf adjustment amount εiFor 2 π rad, then the rotation angle of adjusting nut 2 is
360°。
4~8 are repeated the above steps, until measuring from X, disagreement value A of tri- root post of Y, Z at nearest pointi
Less than 0.05mm, leveling is completed.
