Form, and the diameter of oil filler point section is more than the diameter of screwed hole section；Described plug (2) is contained in clamp body (1)
Centre bore (1a) screwed hole section at, the right part of this plug reaches in the oil filler point section of centre bore (1a)；
Described clamp body (1) is four-part form multidiameter structure, be followed successively by from left to right the first cylindrical section (1b),
Two cylindrical sections (1c), the 3rd cylindrical section (1d) and the 4th cylindrical section (1e), wherein first, second and third circle
The diameter of shell of column increases successively, the diameter of described 4th cylindrical section (1e) between second and third cylindrical section (1c,
Between 1d)；The 1/2-2/3 of a length of clamp body (1) length of described first cylindrical section (1b), and the
The screwed hole section of position correspondence clamp body centre bore (1a) of one cylindrical section (1b) and oil filler point section left part；
It has been evenly distributed at least 3 heavy stand holes (1f) on 3rd cylindrical section (1d) of described clamp body (1),
This heavy stand hole is axially arranged and left large and right small along clamp body (1)；Described 3rd cylindrical section (1c) is also gone up
Have a radial hole (1g), at the outer aperture of this radial hole, be connected by screw a described oil return pipe
, and the inner of radial hole (1g) connects in the middle part of the oil filler point section of clamp body centre bore (1a) (3).
In technique scheme, the clamp body (1) of the present invention is by being located in the spiral shell in heavy stand hole (1f)
Follow closely the main shaft with lathe to fix, and the 4th cylindrical section (1e) of clamp body (1) realizes sealing.During clamping,
First workpiece is sleeved on first cylindrical section (1b) of clamp body (1), then by hydraulic pump to clamp body (1)
Centre bore (1a) oil filler point section injection pressure oil, owing to the material of clamp body (1) is spring steel, this
Sample just can make the first cylindrical section (1b) distending of clamp body (1), thus in the centre bore of swelling workpiece is whole
Wall, and then realize centering, and centering precision is high；After completing processing, open the valve being connected with oil return pipe (3)
Door, thus can oil return, release, now first cylindrical section (1b) of clamp body (1) reduces, thus just
In unloading workpiece.It addition, we can regulate centre bore (1a) by the degree of depth that is screwed into adjusting plug (2)
Oil filler point section oil pressure, thus adjust the size of tension force.
Using above technical scheme, workpiece can very effectively be felt relieved by the present invention, and centering precision is high, and
The simple in construction of the present invention, it is easy to implement, easy to use, there is good practicality.
In order to consider sealing, the 4th cylindrical section (1e) periphery of described clamp body (1) is provided with one
Cannelure (1h), and an annular seal groove (1m) it is provided with in the right side of the 4th cylindrical section.
Beneficial effect: workpiece can very effectively be felt relieved by the present invention, centering precision is high, and the present invention
Simple in construction, it is easy to implement, easy to use, there is good practicality.
