Abstract
A kind of expandable 3D printing parallel institution of working space of the present invention, it includes pressure pin, sliding slot, gear, axis, rack, sliding block, bar, spring, contiguous block, moving platform.It uses single linear drives source, both can straight line driving mechanism, also can be exchanged into rotation driving, then by the transmission campaign of connecting rod and power, so as to reach the characteristic for the transmission that can change parallel institution, extension mechanism diversity, expands the purpose of working space.
Description
Technical field
The present invention relates to parallel institution field, more particularly to a kind of expandable 3D printing parallel institution of working space.
Background technology
Parallel institution is compact-sized with the rigidity of structure is big, bearing capacity is strong, positioning and kinematic accuracy are high, and with higher
Practical value.Therefore the structural body of 3D printer becomes a kind of trend using parallel institution.But its shortcoming it is clear that its
Working space is small, and range of movement is small.It can realize that the mechanism working space of 3D printing is very limited at present, if desired for large-sized
Article is with regard to extremely difficult.At present, the main means that overcome are to increase the free degree of parallel institution, are driven so just having to increase
It is dynamic, so as to greatly add the cost of control, and the precision of movement can be reduced.This seriously affects parallel institution and further should
With.So it is particularly important that inventing a kind of working space expandable 3D printing parallel institution.
At present it is not yet found that relevant report using a kind of expandable 3D printing parallel institution of working space.
The content of the invention
The object of the present invention is to provide a kind of expandable 3D printing parallel institution of working space, it is straight by using rack
Line drives and gear rotation driving, the mutual cooperation with all parts, so that mutual conversion.Pass through the transmission campaign of connecting rod again
With power, so as to reach the characteristic for the transmission that can change parallel institution, extension mechanism diversity, expands the work of 3D printing mechanism
The purpose in space.
The present invention reaches above-mentioned purpose using following technical scheme：
A kind of expandable 3D printing parallel institution of working space of the present invention, it is fixed on sliding slot 1, gear 7 including pressure pin 5
It is fixed as one with axis 6.Rack 2 is fixed as one with sliding block 3.Bar 8 is fixed with axis 6.Spring 4 connects contiguous block 12 and sliding block 3,
Contiguous block 12 is hinged with axis 3.The hinged-hinged bar 8 of moving platform 9 and bar 10.Sliding slot 11 is fixed.Above section is only the mechanism
1/2。
The present invention's has the prominent advantages that：
It uses single linear drives source, both can straight line driving mechanism, also can be exchanged into rotation driving, then pass through connecting rod
Transmission campaign and power, so as to reach the characteristic for the transmission that can change parallel institution, extension mechanism diversity, it is empty to expand work
Between purpose.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the expandable 3D printing parallel institution of working space of the present invention.
Fig. 2 is the sectional view of Slipper in Fig. 1.
Fig. 3 is a kind of dimensional structure diagram of the expandable 3D printing parallel institution of working space of the present invention
In figure：Sliding slot 1,11, rack 2, sliding block 3, spring 4, pressure pin 5, axis 6, gear 7, bar 8,10, moving platform 9, contiguous block
12。
Embodiment
Technical scheme is described further with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of expandable 3D printing parallel institution of working space of the present invention, sliding block 3 can be in sliding slot
Slide, spring 4 is in compressive state all the time so that axis 6 is in bottom, and at this time, the tooth of rack 2 does not connect just with the tooth of gear 7
Touch, when sliding block 3 continues down to slide, axis 6 stops down moving, and axis 6 is contacted with pressure pin 5 and formed hinged.At this time, rack 2
Tooth and gear 7 tooth contact, so as to be rotated with moving gear 7 around contiguous block 12.So as to which driven rod 8 rotates, at this time, contiguous block
12 up slide along sliding block 3.This process completes slip driving and switchs to rotation driving.So as to drive the movement of moving platform 9 various
Property and job enlargement.
Obviously, bar 10 drives the effect for switching to rotation driving since gear 7 is slided with rack 2, drives the movement of moving platform 9
Diversity and job enlargement.
