Description
Technical field
The utility model is related to a kind of special high pulling torque rotary type joint power device, more particularly to a kind of being applied to is revolved
Turn the gyrator in joint.
Background technology
Common rotary type joint power device, i.e., cause revolving part radially to rotate by power, when reversion resets
It is also required to power.The power that radial rotary is produced can be as the power source of rotary shaft.
The utility model of Patent No. 201410395121.0, discloses a kind of unpowered rotation binding clasp, including rotation
Oil cylinder piston, cylinder block, nitrogen spring, cylinder cover and pressure arm, the inner chamber of cylinder block are movably installed with rotary oil cylinder work
Plug, the upper surface of big end and is placed with several nitrogen springs around piston rod A.This utility model utilizes high pressure sealing nitrogen
Gas spring-advance simultaneously passes through the rotation of rotary oil cylinder piston to Workpiece clamping, it is not necessary to additional external power source, by nitrogen spring
Pressurize is clamped.Which passes through the cooperation of the up and down motion of rotary oil cylinder piston and the rotary steering groove of itself and steel ball ball, makes
Also rotary motion while rotary oil cylinder piston moves up and down is obtained, the part of stationary balls ball is can not axially-movable up and down
, that is to say, that rotary oil cylinder piston can only do upper and lower axially-movable and rotation radial motion simultaneously.
However, in the practical application of rotary type joint power device, often only requiring that revolving part radially runs, no
Allow to do upper and lower axially-movable simultaneously.Joint Universal rotary rotating shaft such as robot:With the continuous progress of robot technology, industry
Requirement more and more higher of the field to joint of robot Universal rotary rotating shaft, its performance are also being improved constantly, and function is increasingly perfect how
Ensure the crudy of parting lines, the Proper Match of joint, pressurize ability, grasp force and operating rate is most important
's.Existing parts machining requirement can have been met substantially with made with high precision line at a high speed.But the sequence of technique and nonstandard
Requirement of the accurate characteristic to industrial robot is very high.The key of robot is to repeat crawl and resetting.To Universal rotary
Axle reliability and the accuracy requirement for repeating are higher.And servomotor drives Universal rotary rotating shaft cost high, at present
Conventional Universal rotary rotating shaft is:Servomotor drive-type.Servomotor driving does not require nothing more than Universal rotary axle and can only do radially fortune
Dynamic, and reciprocating motion is required for electric power.It is outer that the current whole world does not also utilize the reset of the technology such as nitrogen spring production to be not required to
The Universal rotary rotating shaft of portion's power.
Excavator revolute joint for another example:The development of excavator industry be unable to do without hydraulic-driven, and initial excavator is manual
, having till now more than 130 years from utility model, period is experienced by steam drive bucket revolving shovel to electricity
Power drives and internal combustion engine drives revolving shovel, the progressively development of the fully automatic hydraulic excavator of application mechanical-electrical-hydraulic integration technology
Process.First hydraulic crawler excavator is by the utility model success of ripple Crane factory of f France.Due to the application of hydraulic technique, 20th century
Have the suspension type excavator that hydraulic hoe is equipped with tractor the forties.Nineteen fifty-one, the all-hydraulic backacter of First
Released by Poclain (ripple Crane) factory for being located at France, so as to the technology development field in excavator has started brand-new space.
Phase early 1950s and mid-term develop towed rotary hydraulic digger and crawler type all-hydraulic excavator in succession.Initial stage
The hydraulic crawler excavator of trial-production is the hydraulic technique using aircraft and lathe, lacks the hydraulic pressure unit suitable for the various operating modes of excavator
Part, workmanship are not sufficiently stable, and auxiliary equipment is not complete yet.From the sixties in 20th century, hydraulic crawler excavator is entered to be promoted and flourishing
Quickly, yield surges for developing stage, excavator manufactory of various countries and kind increase.Between 1968-1970, hydraulic crawler excavator yield
The 83% of excavator total output has been accounted for, 100% has been close at present.But all excavators have external joint drive oil cylinder, this kind of
The drawbacks of oil cylinder is that service life is short, because oil cylinder is for external, late stage process process etc. is required high, causes to produce into
This is high;Separately because oil cylinder is needed in itself installed in big arm of digger, so as to jack-up forearm, cause oil cylinder stroke itself long, and
Because excavator needs to be bent downwardly power greatly, making oil cylinder needs to make greatly its cylinder diameter, and therefore oil cylinder weight itself is very big, causes to dig
Pick machine action is restricted.
The hinge rotary shaft of door for another example:And with scientific and technological progress, the development of automobile industry, automatically turn on, close automatically
Close hydraulic door industry development also quite swift and violent, but hydraulic door major part is to support to open and close with hydraulic cylinder now, hydraulic pressure
Cylinder installation site leverages the size that personnel pass in and out space, and open and close hinge rotary shaft is required to hydraulic power.
Utility model content
For solving, in the application of numerous rotary type joint power devices, to only require that revolving part radially runs, do not permit
Perhaps the problems such as simultaneously doing upper and lower axially-movable, and reset without the need for exterior power, the utility model devises a kind of special big torsion
Square rotary type joint power device.
It includes reciprocating piston, the guide being connected with piston, is respectively provided with master in piston end and guide end
Dynamical system and reset dynamical system;Guide is connected to piston rod, is equipped between described piston rod and guide
The axially reciprocating for being directed to part is converted to the mechanism of piston rod radial rotating.
Guide described further is embedded in guiding steel ball;Arrange on described piston rod and mate taxi driver brother with guiding steel ball
Special formula gathering sill;Guide is moved back and forth and drives guiding steel ball to move along Gothic steel-ball groove, and then drives piston rod radially to turn
Dynamic.
Ball screw attachment structure is adopted between guide described further and piston rod;The axial reciprocating fortune of guide
Dynamic drive piston rod radial rotating.
On piston rod, spiral arranges piston rod steel ball, and guide inwall is provided with mating groove.Guide is moved back and forth and is driven
Piston rod steel ball, and then drive piston rod radial rotating.
Main power system described further is pneumatic system or hydraulic power system or machine driven system;Described answers
Position dynamical system is pneumatic system or hydraulic power system or spring.
Pneumatic system described further is exhaust power unit or gas spring.
Hydraulic power system described further includes liquid injection hole and closed hydraulic cavities.
Cylinder body is set outside guide described further, guide is along the spacing reciprocating motion of cylinder interior.
Further piston rod one end is stretched out outside described cylinder body.
Further piston rod two ends are stretched out outside described cylinder body.
Further piston and guide are integral type structure.
The utility model beneficial effect:In actual applications, either active rotation still resets rotation the utility model
When, piston rod only radially can run, and do upper and lower axially-movable when different.And the reset of the guide of axially-movable up and down
Dynamical system can be nitrogen spring, that is, can achieve the reset of guide when resetting without the need for external impetus, while band piston
Bar radially resets;When being used as rotary joint, power is saved, and the anglec of rotation is easily controlled, the hydraulic cylinder etc. without the need for large volume is excellent
Gesture.
