Description
Technical field
The present invention relates to a kind of mechanical device, and in particular to a kind of hydraulic cylinder of energy clamp piston bar.
Background technology
Hydraulic cylinder be hydraulic energy is changed into mechanical energy, the hydraulic pressure that does straight reciprocating motion (or oscillating motion) performs member
Part.Its simple in construction, reliable operation.During with it to realize reciprocating motion, deceleration device can be removed from, and do not have drive gap,
Stable movement, therefore be used widely in various mechanical hydraulic systems.Hydraulic cylinder power output and piston effective area and
The pressure difference on its both sides is directly proportional；Hydraulic cylinder substantially by cylinder barrel and cylinder cap, piston and piston rod, sealing device, buffer unit with
Exhaust apparatus forms.Hydraulic cylinder is a kind of driving and bears the executive component of big load, usually requires that its energy when moving stopping
Outer load is born long-term and stably without any displacement, that is, needs to clamp in piston rod, with positioning function, nothing
" soft leg " phenomenon.
The content of the invention
The technical problems to be solved by the invention are how will to clamp piston rod, enable hydraulic cylinder when moving stopping
Bear long-term and stably it is outer load and without any displacement.Therefore it is an object of the invention to provide a kind of energy clamp piston bar
How hydraulic cylinder, solution will clamp piston rod, hydraulic cylinder is born outer load long-term and stably when moving and stopping
And the problem of without any displacement.
The present invention is achieved through the following technical solutions：
Cylinder body is inserted in a kind of hydraulic cylinder of energy clamp piston bar, including cylinder body, holder and one end
Piston rod, fluted, the cross sectional dimensions of the groove and the cross sectional dimensions phase of cylinder body are set on the holder
Matching, it is easy to coordinate by the end face of groove and cylinder body, holder is fixed on to the end of cylinder body, it is described
End face is the end face that piston rod can freely stretch；Through hole that is coaxial with groove and connecting is provided with holder, piston rod
Free end passes through through hole.
Further, in addition to the radial direction along through hole, applying on holder is outwards arranged on by the axis of through hole successively
Power hole, fluid chamber and oilhole, one end of the oilhole connect with the outer surface of holder, and the other end passes through fluid chamber and force hole
Connection, the axis in the force hole and the axis of oilhole are vertical with the axis of through hole.Fluid is poured into oil successively from oilhole
In sap cavity and force hole, and pressure is applied to fluid, make the deformation of bottom of oilhole, the inside of radial direction is produced to the side wall of through hole
Pressure, and then clamp the piston rod through through hole.
Further, the holder is elastomeric material.Elastomeric material refers to large deformation occurs in stress, after withdrawing from external force
The material of its approximate original shape size is replied rapidly.
Further, the distance of the hole wall of the hole bottom distance through hole in the force hole is 0.1mm-10mm.When the distance is
When 0.1mm, without applying excessive pressure to fluid, piston rod can just be clamped, but the use longevity of holder now
Order shorter, about 2000min；When the distance is 10mm, larger pressure need to be applied to fluid, piston rod could be clamped
Firmly, but now the service life of holder is more normal, about the former 6-8 times.
Further, force hole, fluid chamber and the oilhole have several.By using it is multiple force holes, fluid chamber and
Oilhole carries out blessing operation to piston rod, improves the stability of clamping.
Further, in addition to pressure sensor, controller and display, the pressure sensor are located at the inwall of through hole
On, and face force hole, the controller are connected with pressure sensor and display respectively.And oilhole passes through hydraulic pressure oil pump feed.
When holder carries out clamping operation to piston rod, the size of the blessing power is passed to controller, controller by pressure sensor
The signal is received, and the signal is shown to the force size on a display screen, being easy to worker to check the holder.Pressure sensing
Device is a kind of sensor the most commonly used in industrial practice, and pressure sensor is called piezoelectric transducer, and its electric field is with stress
Change and change.Controller uses PLC, and its concrete model is one kind in following model：Mitsubishi PLC FX1S-10MT-001,
Mitsubishi PLC FX1N-24MR-001, Mitsubishi PLC FX2N-32MR-001 and Mitsubishi PLC FX2N-64MR-001.Display is
Light-emitting diode display, concrete model ULT-3361BX.
Pressure sensor, controller and display in above-mentioned are prior art, can commercially be bought.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of hydraulic cylinder of energy clamp piston bar of the present invention, simple in construction, chucking power is reliable, can implement foot to piston rod
Enough blessing power；
2nd, a kind of hydraulic cylinder of energy clamp piston bar of the present invention,, can in the clamping of hydraulic-driven compared with purely mechanic clamping
Easily and flexibly to arrange the drive devices such as hydraulic pump as needed；
3rd, the hydraulic cylinder of a kind of energy clamp piston bar of the invention, during clamping, implement to complete the speed clamped soon, instead
Answer speed fast；

Match with the cross sectional dimensions of cylinder body 1, be easy to coordinate by the end face of groove 3 and cylinder body 1, by holder
8 are fixed on the end of cylinder body 1, and the end face is the end face that piston rod 2 can freely stretch；Set on holder 8
There is through hole 4 that is coaxial with groove 3 and connecting, the free end of piston rod 2 passes through through hole 4.
Further, in addition to the radial direction along through hole 4, outwards it is arranged on holder 8 successively by the axis of through hole 4
Force hole 7, fluid chamber 6 and oilhole 5, one end of the oilhole 5 connect with the outer surface of holder 8, and the other end passes through fluid chamber 6
Connected with force hole 7, the axis in the force hole 7 and the axis of oilhole 5 are vertical with the axis of through hole 4.By fluid from oilhole 5
In pour into successively in fluid chamber 6 and force hole 7, and pressure is applied to fluid, makes the deformation of bottom of oilhole 5, to the side wall of through hole 4
The inward pressure of radial direction is produced, and then clamps the piston rod 2 through through hole 4.
Further, the holder 8 is elastomeric material.Elastomeric material refers to, in stress generation large deformation, withdraw from external force
Reply the material of its approximate original shape size rapidly afterwards.
Further, the distance of the hole wall of the hole bottom distance through hole 4 in the force hole 7 is 0.1mm-10mm.When the distance
For 0.1mm when, without applying excessive pressure to fluid, piston rod 2 can just be clamped, but holder 8 now makes
It is shorter with the life-span, about 2000min；When the distance is 10mm, larger pressure need to be applied to fluid, could be by piston rod
2 clamp, but the service life of holder 8 now is more normal, about the former 6-8 times.
Further, force hole 7, fluid chamber 6 and the oilhole 5 have several.By using multiple force holes 7, fluid
Chamber 6 and oilhole 5 carry out blessing operation to piston rod 2, improve the stability of clamping.
