Abstract
The utility model discloses a kind of gap screw mandrel group that disappears of 3D printer, including screw mandrel, complex, described complex includes outer nut, inner nut and spring, described screw mandrel bottom is fixed on machine shaft, screw mandrel is to be threadedly coupled with outer nut, it is hollow built in outer nut, outer nut bottom opening is in hexagonal configuration, outer nut top sets round table surface, several connecting holes are provided with table top, inner nut bottom is cylinder in hexagonal prismoid top, is caught in spring on inner nut and is pressed into outer nut inner chamber, inner nut is connected with wire rod thread.Outer nut, inner nut under the action of the spring, produce opposition, so that outer nut produces upward power, eliminate screw mandrel and the upward gap of outer nut, inner nut produces downward force, eliminates screw mandrel and the downward gap of inner nut.Reach in the complex that outer nut and inner nut form while eliminate the gap to screw mandrel up and down.Position tolerance minimum caused by gap is moved up and down so as to reach complex.
Description
Technical field
The utility model belongs to 3D printing part technical field, more particularly to a kind of gap screw mandrel group that disappears of 3D printer.
Background technology
3D printing（3DP) be rapid shaping technique one kind, it be one kind based on mathematical model file, with powder
Shape metal or plastics etc. can jointing material, come the technology of constructed object by way of successively printing.3D printing is typically to use
Digital technology file printing machine is realized.Often it is used for modeling in fields such as Making mold, industrial designs, it is rear gradually to use
In the direct manufacture of some products, there are the parts formed using the printing of this technology.The technology is in jewelry, footwear, work
Industry design, building, engineering and construction（AEC）, automobile, Aero-Space, dentistry and medical industries, education, GIS-Geographic Information System, soil
Wood engineering, gun and other field have all been applied.Prior art, 3D printer need very stable printing environment, and 3D is beaten
Print needs stable transmission to be accurately positioned, and screw mandrel is connected with nut has gap in itself, causes big error, causes print quality
It is poor.
Utility model content
In view of this, it is necessory to provide the gap screw mandrel group that disappears of 3D printer a kind of, operator can be met in operation 3D
When printing, the 3D products of printing will not cause product printing failure because of gap.
In order to overcome the shortcomings of the prior art, the utility model provides following technical scheme：A kind of 3D printer
Disappear gap screw mandrel group, including screw mandrel, complex, and described complex includes outer nut, inner nut and spring, under described screw mandrel
Portion is fixed on machine shaft, and screw mandrel is with outer nut to be threadedly coupled, and hollow built in outer nut, outer nut bottom opening is in hexagonal
Shape, outer nut top set round table surface, are provided with several connecting holes on table top, inner nut bottom is in hexagonal prismoid top
Cylinder, spring is caught on inner nut and is pressed into outer nut inner chamber, inner nut is connected with wire rod thread.
Preferably, described inner nut bottom hexagonal prismoid is caught in outer nut bottom hexagonal configuration opening, is formed and coordinated.
It is made preferably, described outer nut, inner nut are plastic material.
Preferably, described spring bottom is connected with nut bottom hexagonal prismoid, top is fixed on outer nut inner chamber top
Portion.
Compared with prior art, the technical solution of the utility model can reduce the error of gap band.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is structural representation of the present utility model.
Specific examples below will further illustrate the utility model with reference to above-mentioned accompanying drawing.
Embodiment
Below with reference to accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, 3, the gap screw mandrel group that disappears of a kind of 3D printer, including screw mandrel 1, complex, described is compound
Body includes outer nut 2, inner nut 3 and spring 4, and the described bottom of screw mandrel 1 is fixed on machine shaft, and screw mandrel 1 is with outer nut 2
It is threadedly coupled, hollow built in outer nut 2, the bottom opening of outer nut 2 is in hexagonal configuration, and the top of outer nut 2 sets round table surface, platform
Several connecting holes are provided with face, the bottom of inner nut 3 is cylinder in hexagonal prismoid top, and spring 4 is caught on inner nut 3 and is pressed
Enter in the inner chamber of outer nut 2, inner nut 3 is threadedly coupled with screw mandrel 1.The described bottom hexagonal prismoid of inner nut 3 is caught in the bottom of outer nut 2
Portion's hexagonal configuration opening, formed and coordinated.Described outer nut 2, inner nut 3 are that plastic material is made.The described bottom of spring 4
It is connected with the bottom hexagonal prismoid of nut 2, top is fixed on the inner cavity top of outer nut 3.
Inner nut 3 is inserted in spring 4 and headed into outer nut 2, and bottom coincide, and screw mandrel 1 penetrates inner nut 3, spring 4, outer spiral shell
Mother 2, screw mandrel 1 and inner nut 3 are to be threadedly coupled with outer nut 2, in motor drive screw 1, outer nut 2 and inner nut 3 it
Between effect have a spring 4, eliminate the gap of opposite thread connection when rotating, it is more accurate when so as to print.
Outer nut 2, inner nut 3 under the action of the spring, produce opposition, so that outer nut 2 produces upward power,
Screw mandrel 1 and the upward gap of outer nut 2 are eliminated, inner nut 3 produces downward force, eliminates screw mandrel 1 and the downward gap of inner nut 2.
Reach in the complex that outer nut 2 and inner nut 3 form while eliminate the gap to screw mandrel 1 up and down.So as to reach
It is minimum that complex moves up and down position tolerance caused by gap.
The explanation of above example is only intended to help and understands method and its core concept of the present utility model.It should refer to
Go out, for those skilled in the art, can also be to this on the premise of the utility model principle is not departed from
Utility model carries out some improvement and modification, and these are improved and modification also falls into the protection domain of the utility model claims
