Description
Technical field
It the utility model is related to hydraulic efficiency manipulator technical field, and in particular to a kind of hydraulic efficiency manipulator with internal oil passages
Rotary joint axle.
Background technology
In the last few years, robotics development was very rapid, and robot is led in industry, agricultural, service, medical treatment, military affairs etc.
Domain is applied widely.Manipulator is the important branch of robot technology, can complete various expected tasks.Manipulator presses it
Type of drive can be divided into electric drive, pneumatic, hydraulic-driven, wherein hydraulic driving mechanical have stable movement, load capacity it is big,
Rapidity is good, the advantages that variable speed can be achieved, and is extensively applied to the heavily loaded different areas of activity such as underwater operation.The rotation of manipulator is closed
Section is the critical component of manipulator, and its flexibility, accuracy have been largely fixed the flexibility of manipulator, accuracy.Cause
This design volume is small, and the good manipulator rotary joint portion of flexibility is of great significance.The manipulator of hydraulic-driven at present
Rotary joint is mostly directly connected to using independent hydraulic motor and hydraulic cylinder, and fuel feed pump is external, bulky, easy during motion
Interference is produced with external object, influences the kinematic dexterity of manipulator.
Utility model content
To solve above technical problem, the utility model provides a kind of rotation of the hydraulic efficiency manipulator with internal oil passages and closed
Nodal axisn.
Technical scheme is as follows：A kind of rotary joint axle of the hydraulic efficiency manipulator with internal oil passages, its key are：Including
Joint shaft body, the joint shaft body is interior to be provided with least one hydraulic oil runner, and it is blind that the hydraulic oil runner includes axially shunting
Hole and radially shunting blind hole, the axially shunting blind hole connect to form the hydraulic oil runner with corresponding radial direction shunting blind hole.
Joint shaft body interior is flowed into through axially shunting blind hole using above-mentioned technical proposal hydraulic oil, then from radial direction shunting blind hole outflow
Into in other same axle sleeves with inner flow passage, the flow channel of hydraulic oil is arranged on the inside of joint shaft body, with biography
The rotary joint of system is compared, and is eliminated traditional external oil pipe, is effectively reduced the weight of manipulator rotary joint, improves it
Flexibility ratio, and interference will not be produced during rotation between oil pipe as traditional manipulator.
Further, above-mentioned joint shaft body surface corresponds to the radial direction shunting blind hole and is respectively equipped with the annular groove that confluxes, the footpath
To inner and the corresponding axially shunting blind hole connection, the outer end of the radial direction shunting blind hole and the corresponding institute of shunting blind hole
State annular groove connection of confluxing.Collected in and confluxed in annular groove after radial direction shunting blind hole outflow using this scheme hydraulic oil, and through confluxing
Annular groove is further flowed into next asphalt channel.
Above-mentioned joint shaft body is provided with least one closure gasket groove, between the closure gasket groove and the annular groove alternating of confluxing
Every setting.Sealing ring is installed in closure gasket groove using this programme and can ensure that the relative holding of each annular groove that confluxes is independent sealed, is kept away
Exempt from hydraulic oil leakage.
Array-like annular in shape is provided with multiple axially shunting blind holes on one end end face of above-mentioned joint shaft body, described
Axially the hole depth of shunting blind hole gradually increases along direction clockwise or counterclockwise.Using the axial direction of this scheme difference oil circuit runner
Blind hole depth difference is shunted, so as to which feed flow to be pressed oil to the different positions that the radial direction shunting blind hole of outflow is arranged on joint shaft body
Put, on the one hand do not influence whole joint shaft bulk strength, on the other hand the hydraulic oil after multiple axially shunting blind hole shuntings can
Flowed into through different asphalt channel different by control unit, realize the built-in of whole hydraulic machinery arm oil circuit.
The depth of the above-mentioned annular groove that confluxes is less than the depth of the closure gasket groove.It is more preferable using this design sealing effectiveness.
Above-mentioned joint shaft body interior axle is to being provided with cable-through hole.Can be from mistake using the relevant control circuit of this scheme mechanical arm
Passed through in string holes, avoid the interference of outside cabling, another aspect cable-through hole can also mitigate the weight of whole joint shaft body.
Beneficial effect：It is that beneficial effect is that hydraulic oil flows into through axially shunting blind hole using the beneficial effects of the utility model
Joint shaft body interior, then enter after radial direction shunting blind hole outflow in other same axle sleeves with inner flow passage, hydraulic pressure
The flow channel of oil is arranged on the inside of joint shaft body, compared with traditional rotary joint, eliminates traditional external oil pipe,
The weight of manipulator rotary joint is effectively reduced, will not be as traditional manipulator when improving its flexibility ratio, and rotating
Interference is produced between oil pipe.
