Detailed description of the invention
Being described in further detail the purpose of the present invention below by specific embodiment, embodiment can not at this one by one
Repeat, but therefore embodiments of the present invention are not defined in following example.
As described in Fig. 1 to Fig. 3, a kind of rotatable switching 3D printing head, including the 11st, suspension bracket rotates and is arranged on described suspension bracket
Gear train on 1, the printhead 10 being movably arranged on described suspension bracket 20 by omnidirectional mechanism 9, described printhead 10 rear end leads to
Crossing oscillating rod device and connecting gear train, be provided with the motor 7 of gear train in described oscillating rod device, suspension bracket 20 plays a supportive role.
Specifically, described gear train includes sun bevel gear the 3rd, the satellite that the 1st, fold-line-shaped train installing plate engages successively
Bevel gear 4 and bevel planet gear 6, described suspension bracket 20 is provided with ladder projection 19, and described train installing plate 1 passes through the first axle
Hold 2 rotations to be installed on described ladder projection 19, the setting that described sun bevel gear 3 is rotated by the second gear position limiting screw 17
On described ladder projection 19, described satellite bevel gear 4 is installed by the train that is arranged on that the 3rd gear position limiting screw 18 rotates
On plate 1, described bevel planet gear 6 is fixing with the rotating shaft of described motor 7 to be connected, and the rotating shaft front end of described motor 7 passes through second
Bearing 5 and the first gear position limiting screw 16 connect train installing plate 1.
Specifically, described oscillating rod device includes the planet pendulum 8 for accommodating motor 7, and one end of described planet pendulum 8 sets
Being equipped with the end cap 14 being connected by head bolts 15, the other end connects described printhead 10 rear end by screw 13.
Specifically, described omnidirectional mechanism 9 uses spherical linkage, and described spherical linkage includes rotating sphere and ball seat 12,
Described ball seat 12 is arranged on suspension bracket 20, and described rotating sphere connects printhead 10.
Specifically, described suspension bracket 20 is additionally provided with the regulation screw 11 for fixing omnidirectional mechanism 9 axial location, with
Facilitate installation and the dismounting of omnidirectional mechanism 9.
In another embodiment of the invention, described omnidirectional mechanism 9 uses universal bearing, and the outer ring of described universal bearing is solid
Being scheduled on suspension bracket 20, inner ring connects printhead 10, is provided with ball or roller between outer ring and inner ring.
The gear train of described embodiment is made up of three cone planetary gears, rotates bevel planet gear 6 and middle satellite
Bevel gear 4 rotates around sun bevel gear 3.When changing printhead 10, bevel planet gear 6 is driven to rotate by motor 7, and then driven wheel
Being that installing plate 1 turns an angle around ladder projection 19, the bevel planet gear 6 of gear train rotates around sun bevel gear 3, by ten thousand
Printhead 10 is driven to rotate around rotary shaft to mechanism 9, so that another printhead 10 horizontal positioned.During conversion printhead 10,
Owing to the position of previous printhead 10 has been the minimum point of movement locus, so printhead 10 will not occurring and beat during conversion
The problem that printed material material collides.
With regard to orientation planetary in the course of work, i.e. process of revolution points to constant, can be pushed away by mathematical analysis
Go out gear train design to want, as sun gear and planetary gear should have identical number of teeth z and modulus m (i.e. reference circle equal diameter).
As shown in Figure 4, Introduction on Principle is as follows:
ω is C wheel revolution angular speed
vb=ω (r1+r2)
D point fixes vd=0, B take turns spin velocity
So ve=2 ωbr2=2 ω (r1+r2)
vc=ω (r1+r3+2r2)
Work as ve=vc, C takes turns not rotation, and (i.e. C takes turns spin velocity ωbIt is zero), now r1=r3
Above-described embodiment is the present invention preferably embodiment, but embodiments of the present invention are not by above-described embodiment
Limit, the change made under other any Spirit Essence without departing from the present invention and principle, modifications, replacement, combination, simplification,
All should be the substitute mode of equivalence, be included within protection scope of the present invention.
