In conjunction with Fig. 1, Fig. 9, Figure 10, described waist rotation member 21 is provided with large arm brake structure 90, described large arm brake structure
Including the basal disc 921 being fixedly installed on waist rotation member, a pair brake(-holder) block 922 being arranged on basal disc, it is slidably arranged in basal disc
On solution lock slide 923;Being fixed with brake disc in described large arm, a pair brake(-holder) block is symmetrical set the periphery in brake disc,
One end of a pair brake(-holder) block is hinged and other end elasticity connects;Described solution lock slide elasticity is connected on basal disc, solves on lock slide
Be provided with translatable enter a pair brake(-holder) block elasticity connect one end to open the wedge 924 of a pair brake(-holder) block.
In above-mentioned large arm brake structure 90, described basal disc is fixed on waist rotation member by support column 925;Set on support column
There is swivel pin;The pair of brake(-holder) block includes the first brake(-holder) block being positioned at left side and is positioned at second brake(-holder) block on right side, the first system
The left end of moving plate and the left end of the second brake(-holder) block are hinged on swivel pin, the right-hand member of the first brake(-holder) block and the right-hand member of the second brake(-holder) block
Connected by the first coil tension spring elastic 9221;The right-hand member of the first brake(-holder) block is provided with the first fore-set, and the right-hand member of the second brake(-holder) block sets
Having the second fore-set, the first fore-set and the second fore-set to be oppositely arranged, the first fore-set and the second fore-set are positioned at the first coil tension spring;Institute
State the first brake(-holder) block and the equal semicircular in shape of the second brake(-holder) block, the first brake(-holder) block and the second brake(-holder) block and surround brake disc 912.
In above-mentioned large arm brake structure 90, described solution lock slide is provided with a pair alignment pin 927, a pair alignment pin and wedge shape
It is arranged on before and after block on solution lock slide;The pair of alignment pin includes the first alignment pin and the second location being symmetrical set
Pin, the right-hand member of described first brake(-holder) block is provided with the first hole, location 9222, and the right-hand member of the second brake(-holder) block is provided with the second hole, location, the
Under the elastic force of one coil tension spring, when the first fore-set and the second fore-set offset, first alignment pin solved on lock slide of translation and
Second alignment pin can correspondingly insert in the first hole, location and the second hole, location.
In above-mentioned large arm brake structure 90, described basal disc is provided with setting block 928, erects block and is provided with the second coil tension spring
9281, one end of the second coil tension spring connects erects block, and the other end of the second coil tension spring connects solution lock slide.
In practical operation, the workflow of a kind of operating robot being provided with swing arm of the present invention is as follows:
First, medical worker holds manipulation hands 23, unties the large arm brake structure 90 locking to large arm 22, and brake knot
Structure 70 and second brake structure 700 locking to waist rotation member 21, rotate large arm 22 or waist rotation member 21, or make waist rotation member
21 translate along the first horizontal guide rail 11 and the second horizontal guide rail 12, make the mechanical claw hand 30 on swing arm 80 close to object to be taken
Place.
Second, under the driving of the first driver element, the swing of swing arm 80 can drive mechanical claw hand 30 thereon to swing,
Under the driving of the second driver element, mechanical claw hand 30 is rotatable.
3rd, in mechanical claw hand 30, the first servomotor 618 drives worm gear 616 worm screw 617 action, and worm and gear drives
The left hand thread bar 611 and the right-handed thread bar 612 that are fixedly connected rotate;Left hand thread bar drives the first lifting in the first locking body
Chassis 622 declines, and the first lifting chassis drives the first latch segment 624 to decline, and the first latch segment drives the first sliding pin 621 to decline,
Owing to the first slide slot 511 is obliquely installed, the first sliding pin being vertically lowered can order about the cleft hand in first pair of cleft hand 51 around it
Rotate with the hinged place of cleft hand frame 40, make first pair of cleft hand swing in opposite directions;Right-handed thread bar 612 drives in the second locking body
Second lifting chassis 632 rise, second lifting chassis drive locking plate 634 rises, locking plate drive second sliding pin rise, by
It is obliquely installed (direction that the second slide slot tilts is in opposite direction with what the first slide slot tilted) in the second slide slot 521, therefore,
The cleft hand that the second sliding pin vertically risen orders about in second pair of cleft hand 52 rotates around it with the hinged place of cleft hand frame 40, makes the
Two pairs of cleft hands swing in opposite directions;So, two pairs of cleft hands 50, in drawing shape in, are used for capturing object.
Above content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, the most all will change, this specification content should not be construed as this
Bright restriction.
