Background technology
The people who understands three-eccentric-butterfly-valve knows that the O-ring seal of three-eccentric-butterfly-valve is by the resulting ellipse of a plane bevel circular cone, and is very difficult to the measurement of the long and short shaft size of ellipse, and the accuracy of directly measuring is very low, and error is very big, directly influences the quality of product.Sealing to product also just is difficult to influence sealing effectiveness to guarantee.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of measurement mechanism of three-eccentric-butterfly-valve O-ring seal is provided, solved O-ring seal measuring error problem bigger than normal, it is simple accurate to measure, and can guarantee sealing effectiveness well.
According to technical scheme provided by the invention, the measurement mechanism of said three-eccentric-butterfly-valve O-ring seal, characteristic is: comprise the clamp body that is installed on the vertical lathe, the centre of gyration of clamp body overlaps with the centre of gyration of vertical lathe; At the said clamp body installing and locating body that tilts, clamping workpiece on the positioning body; At the centre of gyration installation bridge of said clamp body, level is installed gauge rod on the top of gauge rod frame; The angle that forms between two sides of the centre of gyration of said clamp body with the axial section of processed workpiece is divided equally; Form angle between the centre of gyration of said vertical lathe and the vertical center line of workpiece, this angle equals the angle that forms between the centre of gyration and the butterfly valve pipe laying center line of vertical lathe; One end overhang bridge of said gauge rod, the end of gauge rod external part are the tool setting point of vertical lathe lathe tool.
Said positioning body is circular, forms boss in the upper surface of positioning body, and the lower end, the outside of boss is the carrying plane vertical with boss.
The length that is used for the installed surface of installing and locating body on the said clamp body is H, and the plane parallel of this installed surface and the clamping workpiece on positioning body, the length of workpiece axial section are L2, and L2＞H.
The measurement mechanism of three-eccentric-butterfly-valve O-ring seal of the present invention has solved O-ring seal measuring error problem bigger than normal, and through transforming the actual, measured dimension that the measurement of gauge rod extension elongation is guaranteed O-ring seal, it is simple accurate to measure, and has guaranteed sealing effectiveness well.

Embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
Like Fig. 1～shown in Figure 4: the measurement mechanism of three-eccentric-butterfly-valve O-ring seal comprises clamp body 1, positioning body 2, workpiece 3, gauge rod frame 4, gauge rod 5, boss 6, carrying plane 7 etc.
The present invention includes the clamp body 1 that is installed on the vertical lathe, the centre of gyration of clamp body 1 overlaps with the centre of gyration of vertical lathe; At the said clamp body 1 installing and locating body 2 that tilts, clamping workpiece 3 on the positioning body 2; At the centre of gyration installation bridge 4 of said clamp body 1, level is installed gauge rod 5 on the top of gauge rod frame 4;
Said workpiece 3 is installed on the positioning body 2 with certain angle, and the lathe tool of vertical lathe is processed workpiece 3, and what obtain after the processing is the three-eccentric-butterfly-valve O-ring seal; The angle of two sides of the axial section of the three-eccentric-butterfly-valve O-ring seal that obtains after said workpiece 3 processing is 2 β; The centre of gyration of said clamp body 1 is the angular bisector of angle 2 β that form between two sides of the axial section of processing back workpiece 3; Form angle between the vertical center line (being the vertical center line of workpiece 3) of the centre of gyration of said clamp body 1 (being the centre of gyration of vertical lathe) and positioning body 2, the angle that forms between the center line of the centre of gyration of this angle and vertical lathe and butterfly valve pipe laying is consistent; One end overhang bridge 4 of said gauge rod 5; The end of gauge rod 5 external parts is the tool setting point of vertical lathe lathe tool, and the length of gauge rod 5 external parts is L1, and the length L 1 of this external part is by the geometric relationship of clamp body 1 and workpiece 3; Directly from AutoCAD figure, measure, to guarantee the size L2 of workpiece 3;
As shown in Figure 2, said positioning body 2 is circular, forms boss 6 in the upper surface of positioning body 2, and the lower end, the outside of boss 6 is the carrying plane 7 vertical with boss 6; When clamping workpiece 3, boss 6 is positioned at the inboard of workpiece 3, and carrying plane 7 cooperates with the lower surface of workpiece 3, is used to support workpiece 3;
The length that is used for the installed surface of installing and locating body 2 on the said clamp body 1 is H, the plane parallel of this installed surface and the clamping workpiece 3 on positioning body 2, and the length of workpiece 3 axial sections is L2, and L2＞H, can prevent that like this vertical lathe lathe tool from running into anchor clamps.
The course of work of the present invention: workpiece 3 is the angle [alpha] clamping on positioning body 2, and the angle of the center line of the centre of gyration of this angle [alpha] and vertical lathe and the pipe laying of butterfly valve is consistent; The length L 1 of gauge rod 5 external parts is confirmed through the geometric relationship of clamp body 1 and workpiece 3, and is directly measured by AutoCAD; During processing work, the lathe tool of vertical lathe is to the tool setting point of good gauge rod 5, and the workpiece 3 that processes is exactly required size L2.
