Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical scheme
Solution.
Expressed structure of the invention, is a kind of machine tool hydraulic chuck as shown in Figure 1, Figure 2, is common to clamping circular bar work
Part, the chuck includes overcoat 1.
In order to solve the problem of prior art is present and overcome its defect, the hair of the clamping efficiency of circular bar workpiece is realized
Improving eyesight, the technical scheme that the present invention takes is：
As shown in Figure 1 and Figure 2, machine tool hydraulic chuck of the invention, in the endoporus of described overcoat 1, setting is coaxial therewith
Line and the inner core 2 coordinated, the front end of described inner core 2 is the structure of thin walled cylinder body 5, the inner face closure of described thin walled cylinder body 5；Institute
The cylindrical formation of the endoporus and workpiece of the thin walled cylinder body 5 stated is slidably matched；The outer surface of described thin walled cylinder body 5 with it is described outer
The bore area formation tight fit of set 1；Oil groove 9 is provided with the outer surface of described thin walled cylinder body 5, described oil groove 9 is with adding
Press oil communication.
The hydraulic clamp head of the present invention is to transmit pressure by the use of hydraulic oil as medium, so that chuck clips workpiece.
Hydraulic oil is full of in chuck, plunger is pushed ahead in the presence of external force, hydraulic oil transmission pressure acts on chuck front end
Thin walled cylinder body, makes it produce micro elastic deformation, so that workpiece is clipped, it is uniform due to deflection very little, and very, so will not
Workpiece is deformed, and will not disfiguring workpiece surface.
The present invention is by adopting the above-described technical solution, make it have simple in construction, convenient processing and manufacture, operating efficiency height
The advantages of.And centering precision is also greatly improved.
Described pressurized oil lines are：
Overcoat oilhole 6 is set on described overcoat 1；Inner core oilhole 7 is set on described inner core 2；Described overcoat
The front end of oilhole 6 is connected with described oil groove 9.
The profile of described overcoat 1 is the cone that point diameter is less than rear end；Described inner core 2 is after point diameter is less than
Hold the stairstepping of diameter；Described inner core oilhole 6 is connected with overcoat oilhole 7 in step-like shoulder end.
The rear port of described inner core oilhole 6 be located at inner core 2 axis, described inner core oilhole 6 rear port with it is interior
Between the rear end of core, the cylindrical hole for setting with the coaxial line of inner core 2 and being connected with described inner core oilhole 6 is set in the cylindrical hole
There is plunger 3.
The effect of plunger 3 is to realize that the clamping force that additional mechanical motion mechanism is produced can pass to hydraulic clamp machine
Structure.
It is located at the front of plunger 3 in described cylindrical hole, sealing ring 4 is set.
Described sealing ring 4 ensure that the sealing property of plunger 3 and plunger hole, relative motion and will not can produce
Leakage.
Deflation structure is set on described overcoat 1, the deflation structure includes air bleeder screw plug 8, and the spiro pluging hole coordinated with it,
The spiro pluging hole connects described oil groove 9 with the outer surface of described overcoat 1.
When deflating, it is necessary to which air bleeder screw plug 8 is rotated to direction upward, air bleeder screw plug 8 is then unscrewed, by pressurized oil lines
In gas discharge, and can suitably supplement pressure oil.
