By technique scheme, a kind of forearm of the present invention is provided with the robot of fixing anglec of rotation execution end
Operation principle is as follows:
First, in adjutage, power set drive power transmission shaft to rotate, and power transmission shaft drives gear wheel to rotate, canine tooth wheel driving
Dynamic second middle gear rotates, and the second middle gear drives the first little gear to rotate;Described second middle gear drives the second stud
Declining, the second stud drives the second telescoping mechanism to decline, and described first little gear drives the first stud to rise, the first spiral shell
Cornice moves the first telescoping mechanism and rises;First telescoping mechanism drives swing mechanism to rise, and the second telescoping mechanism drives and swings
Guiding mechanism declines, and first the first axle and the second axle slide in linear gathering sill, and afterwards, the first axle can at a pair
Sliding between flexible guide post, until the first axle is against on the sidewall of sector-like guide groove, now, the second axle is still at straight line
In shape gathering sill;Afterwards, a pair scalable guide post is retracted and is swung in guiding mechanism, and the first axle can be at sector-like guide groove
Interior swing;Afterwards, the second power set drive the first axle to swing in sector-like guide groove, are arranged on swing mechanism
Perform end to swing the most therewith.
Second, when robot is without using the oscillating function of adjutage, the second power set interrupt to the first axle conveying
Power;Afterwards, under the driving of power set, the first telescoping mechanism declines and the second telescoping mechanism rises, and second
Axle slides to reset in linear gathering sill, and the first axle moves to the direction resetted in sector-like guide groove, due to the
One axle has been made to swing in sector-like guide groove, therefore, and the first linear gathering sill of axle offset straight, but, the first axle can be tight
The pair of angled limit that against sector-like guide groove is returned to sector-like guide groove and the connectivity part of linear gathering sill, enters back into straight
Linear gathering sill;When the first axle and the second axle all enter linear gathering sill, swing mechanism is limited.
3rd, perform in end, the driving means in drive mechanism drives annulus to rotate, and annulus drives tooth section thereon
Rotate with unlocked state.In the trip lever being fixedly installed on annulus slips into gathering sill and order about solution lock slide to basal disc
Center translation time, the bar that slides for a pair solved on lock slide translates in a pair slide slot in man-to-man mode, due to
Slide slot is bending, therefore, and sliding bar for a pair and can order about a pair brake(-holder) block elasticity even to the translation of basal disc central line
The one end connect is opened, and so, rotating seat is changed into can freely be revolved by the initial state by a pair brake(-holder) block frictional damping
The state turned.No longer braking rotating seat synchronously with a pair brake(-holder) block, the tooth section on annulus medial wall, i.e. inside annulus
One section of tooth on wall, starts to engage with the second gear, and drives the second gear and be secured to the rotating seat rotation connected,
Rotating seat drives a pair sucker to rotate;When rotating seat rotates 180 degree, tooth section disengages with the second gear,
Meanwhile, trip lever and solve lock slide gathering sill disengage, owing to gathering sill is S-shaped, therefore, trip lever with lead
When groove disengages, solve lock slide and reset, slide bar a pair and reset therewith, one end of a pair brake(-holder) block elasticity connection
Reset the most therewith, a pair brake(-holder) block frictional damping brake disc again, and then braking rotating seat.

In practical operation, a kind of forearm of the present invention is provided with the work that the fixing anglec of rotation performs the robot of end
Flow process is as follows:
First, in adjutage a, power set drive power transmission shaft a614 to rotate, and power transmission shaft drives gear wheel a611 rotation
Turning, gear wheel drives the second middle gear a612 to rotate, and the second middle gear drives the first little gear a613 to rotate;Described
Second middle gear a612 drives the second stud a631 to decline, and the second stud drives the second telescoping mechanism a63 to decline, institute
Stating the first little gear a613 drives the first stud a621 to rise, and the first stud drives the first telescoping mechanism a62 to rise;
First telescoping mechanism drives swing mechanism a64 to rise, and the second telescoping mechanism a63 drives and swings guiding mechanism a65 decline;
First first axle a641 and the second axle a642 slides in linear gathering sill a651, and afterwards, the first axle can at a pair
Slide between flexible guide post a653, until the first axle a641 is against on the sidewall of sector-like guide groove a652, now,
Second axle a642 is still in linear gathering sill a651;Afterwards, a pair scalable guide post a653 retracts to swing and guides
In mechanism a65, the first axle a641 can swing in sector-like guide groove a652;Afterwards, the second power set drive the
One axle a641 swings in sector-like guide groove a652, and the robot being arranged on swing mechanism a64 also performs end 50
Swing therewith.
Second, when robot is without using the oscillating function of adjutage a, the second power set interrupt to the first axle a641
The power of conveying;Afterwards, under the driving of power set, the first telescoping mechanism a62 declines and the second telescoping mechanism a63
Rising, the second axle a642 slides to reset in linear gathering sill a651, and the first axle a641 is at sector-like guide groove a652
The interior direction to reset is moved, owing to the first axle a641 has made to swing in sector-like guide groove a652, therefore, and first
Axle a641 offset straight linear gathering sill a651, but, the first axle a641 can be close to a pair of sector-like guide groove a652
Inclined side is returned to sector-like guide groove a652 and the connectivity part of linear gathering sill a651, enters back into linear gathering sill
a651;When the first axle a641 and the second axle a642 all enters linear gathering sill a651, swing mechanism a64 is limited
Position.
3rd, perform in end 50, the driving means in drive mechanism 60 drives annulus 631 to rotate, and annulus drives
Tooth section 632 thereon and unlocked state 633 rotate.Lead when the trip lever 6331 being fixedly installed on annulus 631 slips into
In groove 6230 and order about solution lock slide 623 when the center translation of basal disc 621, solve and slide bar a pair on lock slide
624 translate in a pair slide slot in man-to-man mode, owing to slide slot 629 is in bending, therefore, to basal disc
The sliding bar 624 for a pair and can order about the elastic one end connected of a pair brake(-holder) block 622 and open of 621 central line translations, so,
Rotating seat 611 is changed into rotatable state by the initial state by a pair brake(-holder) block frictional damping.With a pair
Brake(-holder) block 622 no longer brakes rotating seat 611 synchronously, the tooth section 632 on annulus 631 medial wall, i.e. annulus medial wall
On one section of tooth, start to engage with the second gear 613, and drive the second gear and be secured to connect rotating seat 611
Rotating, rotating seat drives a pair sucker to rotate;When rotating seat 611 rotates 180 degree, tooth section 632 and second
Gear 613 disengages, and meanwhile, trip lever 6331 and the gathering sill 6230 solving lock slide disengage, owing to leading
S-shaped to groove, therefore, when trip lever 6331 and gathering sill disengage, solve lock slide 623 and reset, slide for a pair
Bar 624 resets therewith, and a pair elastic one end connected of brake(-holder) block 622 resets the most therewith, and a pair brake(-holder) block rubs again
Braking brake disc 612, and then braking rotating seat 611.
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, it is right that this specification content should not be construed as
The restriction of the present invention.
