The mating surface of described pressure head is curved surface or inclined-plane;
Described pull bar and described adapter sleeve are slidingly connected, and the link of described pressing plate and described housing bottom are slidingly connected;
Described adapter sleeve is outside equipped with external screw thread.
Another object of the present invention provides a kind of clamping method of workpiece, adopt aforementioned each described clamping device, the connecting surface that is provided with the locating hole that is complementary with described positioning step and is complementary with the mating surface of described pressure head at described workpiece, described workpiece is positioned on the described clamping device by described locating hole and positioning boss, compressed by described pressure head, be fixedly connected with the machine tool chief axis of processing described workpiece by described positioning sleeve, and described machine tool chief axis and the coaxial setting of described positioning boss;
Described machine tool chief axis and described positioning sleeve are threaded connection.
Adopt the clamping device of structure of the present invention and the clamping method of workpiece that valve body class workpiece is carried out clamping, because the housing at clamping device is provided with positioning boss, and this positioning boss is coaxial with machine tool chief axis and pull bar, so can guarantee the axiality of valve body class workpiece processing end, improve the machining accuracy of valve body class workpiece.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is made further explanation:
As shown in Figure 1, clamping device of the present invention comprises pressing plate 2, connecting plate 3, adapter sleeve, 6 pull bars 7 and housing 10.This housing 10 comprises a housing bottom 12, is provided with positioning boss 11 in the outer end of housing bottom 12, and pressing plate 2 is L-type, and the one end is the pressure head 14 of pushing down workpiece 1, and the other end is link; Be provided with the through hole that supply plate 2 passes at housing bottom, the pressure head 14 of pressing plate is arranged on the outside of housing 10, and the link of pressing plate is arranged on the inside of housing 10, is fixedly connected with connecting plate 3.Be provided with through hole at connecting plate 3, pass for pull bar 7; Be provided with pillow block rank 13 at pull bar 7, pillow block rank 13 are arranged on a side that is positioned at housing bottom of connecting plate; Adapter sleeve 6 is sleeved on the pull bar 7, and is fixedly connected with housing 10.The coaxial setting of excircle of pull bar 7, positioning boss 11 and adapter sleeve 6; Be provided with the connecting thread that is connected with machine tool chief axis 8 on the adapter sleeve 6, be provided with Compress Spring 5 between adapter sleeve and connecting plate, this Compress Spring is sleeved on the pull bar.
Pressing plate is minimum to be two and evenly distribution.
At the locating hole that an end setting relative with the processing end of workpiece and positioning boss are complementary, the coaxial setting of machining hole of this locating hole and valve body class workpiece arranges the screw thread that the connecting thread with adapter sleeve is complementary at the main shaft of lathe.
During use, adapter sleeve is connected with machine tool chief axis, at this moment, machine tool chief axis, adapter sleeve and positioning boss should coaxial settings.
