Should be carried out specifically based on the operation principle of the six-degree-of-freedom humanoid mechanical arm of serial-parallel mirror referring to Fig. 1-9 pair
It is bright:
1st, shoulder joint kinesitherapy
Shoulder joint is designed using cascaded structure, and comprising two freedoms of motion independent of one another, its operation principle is respectively:
Shoulder joint one degree of freedom is moved:When first motor 1-1 is rotated, motion passes sequentially through first planet decelerator 1-
2nd, the first shaft joint 1-6 and the first input shaft 1-8 pass to first bevel gear 1-9.First bevel gear 1-9 drives second bevel gear
1-10 is rotated.Second bevel gear 1-10 drives the first output shaft 1-12 motions, drives then first to export connecting plate 1-15 and the
Two output connecting plate 1-16 are rotated.In motor process, the first rotary encoder 1-3 can gather the rotating speed of the first motor 1-1,
On first magnetic coder fixed block 1-38, fixed magnetic coder circuit can gather the corner of the first output shaft 1-12.
Second degree of freedom motion of shoulder joint:When second motor 1-19 is rotated, motion passes sequentially through the second planetary reduction gear
1-20, the second shaft joint 1-23 pass to the first travelling gear 1-23.First travelling gear 1-23 drives the second travelling gear 1-
25 rotate.Second travelling gear 1-25 drives the first sleeve 1-28 to rotate, and drives then the first connecting plate 1-34, the second connecting plate
1-36, second sleeve 1-29, the first housing 1-37 unitary rotations.Due to being equipped between second sleeve 1-29 and the first input shaft 1-8
4th deep groove ball bearing 1-30, the second angular contact bearing 1-31, can realize relative slip between the two, therefore the second motor 1-19 turns
Shoulder joint one degree of freedom is not interfered with when dynamic.In motor process, it is electric that the second rotary encoder 1-21 can gather second
The rotating speed of machine 1-19, the magnetic coder circuit fixed at the second straight-tooth wheel decelerator bonnet 1-34 outer openings can gather second
The corner of travelling gear 1-25.
2nd, elbow joint motion
Elbow joint is designed using parallel-connection structure, and comprising two coupled motions degree of freedom, its operation principle is:
When 3rd motor 2-1 is rotated, it is defeated that motion passes sequentially through third planet decelerator 2-2, the 3rd shaft joint 2-3 and second
Enter axle 2-5 and pass to third hand tap gear 2-6, third hand tap gear 2-6 drives the 4th bevel gear 2-7 to rotate.4th bevel gear 2-7 bands
Dynamic second output shaft 2-8 motions, drive then the 3rd to export the output connecting plate 2-12 of connecting plate 2-11 and the 4th and rotate;
When 4th motor 2-13 is rotated, motion passes to the 3rd travelling gear 2-16 by fourth planet decelerator 2-14.
3rd travelling gear 2-16 drives the 4th travelling gear 2-18 to rotate.4th travelling gear 2-18 drives the 3rd shaft joint 2-5 to turn
It is dynamic.As the 3rd shaft joint 2-5 is fixed with the second shaft end cover plate 2-9 and the second housing 2-20, the rotation of the 4th motor 2-13 is not
The rotation of the second housing 2-20, the rotation can be only caused also to cause to turn between the 4th bevel gear 2-7 and third hand tap gear 2-6
It is dynamic.Therefore the rotation of the 4th motor causes two degree of freedom of ancon while coupled motions.
In motor process, the 3rd rotary encoder 2-3 can gather the rotating speed of the 3rd motor 2-1, the 4th rotary coding
Device 2-15 can gather the rotating speed of the 4th motor 2-13, fixed magnetic coder circuit energy on the second magnetic coder fixed block 2-21
The corner of the second output shaft 2-8 is gathered enough, the magnetic coder circuit fixed at the 3rd housing 2-25 outer openings can gather the
The corner of four travelling gear 2-18.
3rd, wrist joints sporting
Carpal joint is designed using cascaded structure, and comprising two freedoms of motion independent of one another, its operation principle is respectively:
Carpal joint one degree of freedom is moved:When 5th motor 3-1 is rotated, move and passed by fifth line star decelerator 3-2
Pass the first connecting cylinder 3-7.First connecting cylinder 3-7 drives the first steering wheel connector 3-10 to rotate.In motor process, the 5th rotation
Turn the rotating speed that encoder 3-3 can gather the 5th motor 3-1, fixed magnetic coder electricity on the 4th magnetic coder fixed block 3-9
Road can gather the corner of fifth line star decelerator 3-2.
Second degree of freedom motion of carpal joint:When first high-power steering wheel 3-13 is rotated, before driving, wrist fixed plate 3-14 turns
It is dynamic.
