Bar moves back and forth, final that centralizer is driven to move back and forth, and embryo material is pushed and is stepped up to center line.Its major defect can be concluded
For：It is elastic that the non-uniform filament of diameter is not adapted to；Clamping force is non-constant during wire feed；The center of silk is not fixed；And
And the structure of wire feeder is more complex.
To solve the above-mentioned problems, it is special propose a kind of variable diameters silk automatically feed constant force clamping device.
Invention content
In order to which the silk for alloing the wire feeder in fusion sediment method 3D printing technique to adapt to different-diameter automatically is sent into,
And during wire feed, silk automatic centering and holding clamping force are constant, and spy proposes a kind of automatically feeding for variable diameters silk
Constant force clamping device has the features such as simple structure, easy to adjust.
In order to achieve the above object, the technical solution that the utility model is taken is as follows：
A kind of variable diameters silk automatically feeds constant force clamping device, including by 1, one, a holder upright bar 2, two
The slider frame 6, one of wire feed rolls 5, one of swing rod 4, two of sliding block 3, two spring 7, several counterweights 8 constitute a symmetrical pendulum
Bar slide block mechanism；In symmetrical rocker-slider mechanism, two swing rods 4 and two sliding blocks 3 are symmetrically distributed in the both sides of silk 9；Pendulum
One end of bar 4 is hinged with holder 1；The other end of swing rod 4 and sliding block 3 and wire feed rolls 5 are hinged；Two sliding blocks 3 are arranged in sliding block
In frame 6；Several counterweights 8 are the different annulus shape of thickness；One end of upright bar 2 is fixedly connected with slider frame 6, upright bar 2 it is another
There are a boss and guide post in one end, several counterweights 8 are placed on boss successively, and guide post is used in combination to fix；Between upright bar 2 and holder 1
It can opposite sliding；Spring 7 is housed between upright bar 2 and holder 1.
Installation is there are two sliding block 3 in the slider frame 6, and there are one gear, a motors and one for installation on a sliding block 3
A wire feed rolls 5, there are one gear and a wire feed rolls 5 for installation on another sliding block 3；The mutual external toothing in a pair of two gear shapes
Gear, wire feed rolls 5 and gear are disposed coaxially on sliding block 3；A pair of of external gear pump is coaxial relatively solid with two wire feed rolls 5 respectively
Fixed connection；Motor drives a pair of of external gear pump rotation, a pair of of external gear pump that two wire feed rolls 5 is driven to rotate backward.
The power plant that the utility model uses is driven using motor, can be motor driven gear driving, it is possible to use
V belt translation makes its selectivity and stationarity all increase substantially, and improves the required precision of wire feed.

Specific implementation mode
The utility model implementation process is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Fig. 3, a kind of variable diameters silk automatically feeds constant force clamping device, including a holder 1,
One slider frame of wire feed rolls 5, one of swing rod 4, two of sliding block 3, two of upright bar 2, two, 6, springs 7, several counterweights 8；
Two swing rods 4 and two sliding blocks 3 are symmetrically distributed in the both sides of silk 9；One end of swing rod 4 is hinged with holder 1；Swing rod 4 it is another
End and sliding block 3 and wire feed rolls 5 are hinged；Two sliding blocks 3 are arranged in slider frame 6；Several counterweights 8 are the different annulus of thickness
Shape；One end of upright bar 2 is fixedly connected with slider frame 6, and the other end of upright bar 2 has a boss and guide post, several counterweights 8 can be with
It is placed on boss successively, guide post is used in combination to fix；It can opposite sliding between upright bar 2 and holder 1；It is filled between upright bar 2 and holder 1
There is spring 7.
A kind of variable diameters silk automatically feeds constant force clamping device, when supplying silk, is equipped on the boss of column 2
The gravity of counterweight 8 is on column 2 and pushes slider frame 6, and slider frame 6 drives two 4 opposite brackets 1 of swing rod to swing, silk 9
By two wire feed rolls 5, two wire feed rolls 5 apply pretightning force to silk 9, since the diameter of silk 9 is different.
Such as Fig. 2, when the change of 9 diameter of silk is small, column 2 declines, and pretightning force makes two wire feed rolls 5 be clamped silk 9.
Such as Fig. 3, when silk 9 is thicker, swing rod 3 and the horizontal direction angle of mechanism are more than 45 degree, are squeezed by silk 9
The effect of two wire feed rolls 5 and frictional force makes two wire feed rolls, 5 relative separation, column 2 raise, is carried out to larger diameter silk
It clamps；When not having silk to give, two wire feed rolls 5 contact with each other, and before giving silk 9 next time, remove counterweight 8, at this time
The rebound of spring 7 makes upright bar 2 that slider frame 6 be driven to move up, and slider frame 6 is swung with 4 opposite brackets 1 of driven fork, and the swing rod 4 of swing drives
Two 5 relative separations of wire feed rolls of the other end apply counterweight 8, are clamped again to silk 9 when wire feed again.Due to adjusting
During section, the thicker amplitude that attenuates of silk diameter is very small, therefore two idler wheels 5 are detached and had no effect on during
The normal engagement of a pair of of external gear pump.
Holder 1, spring 7, counterweight 8, silk 9 be all centering and two swing rod 4, two of sliding block 3, two wire feed rolls 5,
Slider frame 6 is that opposite central symmetry is distributed, the always centering of silk 9 supply, and with to neutrality.
