Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, explanation is further made to the present invention:
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, and the outer end of housing bottom 12 is provided with positioning boss 11, and pressing plate 2 is in L-type, and its one end is the pressure head 14 pushing down workpiece 1, and the other end is link; Housing bottom is provided with the through hole that supply plate 2 passes, and 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.Connecting plate 3 is provided with through hole, passes for pull bar 7; Pull bar 7 is provided with pillow block rank 13, and pillow block rank 13 are arranged on the side being positioned at housing bottom of connecting plate; Adapter sleeve 6 is sleeved on pull bar 7, and is fixedly connected with housing 10.The excircle of pull bar 7, positioning boss 11 and adapter sleeve 6 is coaxially arranged; Adapter sleeve 6 is provided with the connecting thread be connected with machine tool chief axis 8, is provided with Compress Spring 5 between adapter sleeve and connecting plate, this Compress Spring is sleeved on pull bar.
Pressing plate is minimum to be two and to be uniformly distributed.
Holding relative one end to arrange the locating hole matched with positioning boss with the processing of workpiece, the machining hole of this locating hole and valve body class workpiece is coaxially arranged, and the main shaft of lathe arranges the screw thread matched with the connecting thread of adapter sleeve.
