Summary of the invention
The object of the invention is, during for prior art processing valve body class workpiece, the outside of valve body class workpiece is adopted to position clamping, to the deficiency making valve body class workpiece can not meet axiality requirement, provide a kind of and can meet the clamping device of valve body class workpiece two ends axiality requirement and the clamping method of workpiece.
The object of the invention is to be achieved through the following technical solutions:
First object of the present invention is to provide a kind of clamping device, comprise pressing plate, connecting plate, adapter sleeve, pull bar and housing, described housing is provided with housing bottom, positioning boss is had in the arranged outside of described housing bottom, described pressing plate is in " L " type, its one end is pressure head, the other end is link, described connecting plate is arranged on the inside of described housing, described pressure head is arranged on the outside of described housing, the connecting plate described in link connection of described pressing plate, described pull bar is provided with pillow block rank, described pillow block component level is in the side towards positioning boss of connecting plate, described pull bar is positioned at the opposite side of described connecting plate, described pull bar is set with described adapter sleeve, described pull bar, described positioning boss, described adapter sleeve is coaxially arranged, pull bar position between described connecting plate and described adapter sleeve is provided with spring, described adapter sleeve is fixedly connected with described housing,
The mating surface of described pressure head is curved surface or inclined-plane;
Described pull bar and described adapter sleeve are slidably connected, and link and the described housing bottom of described pressing plate are slidably connected;
Described adapter sleeve is outside equipped with external screw thread.
Another object of the present invention is to provide a kind of clamping method of workpiece, adopt the clamping device described in aforementioned any one, be provided with the locating hole matched with described positioning step and the connecting surface matched with the mating surface of described pressure head on the workpiece, described workpiece is positioned on described clamping device by described locating hole and positioning boss, compressed by described pressure head, be fixedly connected with the machine tool chief axis processing described workpiece by described positioning sleeve, and described machine tool chief axis and described positioning boss are coaxially arranged;
Described machine tool chief axis and described positioning sleeve are threaded connection.
The clamping device of structure of the present invention and the clamping method of workpiece is adopted to carry out clamping to valve body class workpiece, owing to being provided with positioning boss on the housing of clamping device, and this positioning boss and machine tool chief axis and pull bar coaxial, so the axiality of valve body class work pieces process end can be ensured, improve the machining accuracy of valve body class workpiece.

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.
During use, be connected by adapter sleeve with machine tool chief axis, now, machine tool chief axis, adapter sleeve and positioning boss should coaxially be arranged.
Workpiece is sleeved on positioning boss 11 by locating hole, pressure head is pressed in the location profile 15 of outer surface of workpiece setting, pulls pull bar 7, compress location profile 15 by pressing plate 2, thus workpiece blank is clamped, carry out Set and Positioning.
Pull bar can be pulled by cylinder, also pull pull bar by manual or alternate manner, Compress Spring, make pressing plate workpiece pressing, then locking positioning be carried out to pull bar.
