Technical field
The present invention relates to a kind of measurement mechanism of three-eccentric-butterfly-valve O-ring seal, the device that especially a kind of major axis to three-eccentric-butterfly-valve O-ring seal ellipse (or minor axis) size is measured.
Background technology
Understand the people of three-eccentric-butterfly-valve all to know, the O-ring seal of three-eccentric-butterfly-valve is the ellipse obtained by a plane bevel circular cone, and to the measurement of the long and short shaft size of ellipse very not easily, the accuracy directly measured is very low, and error very greatly, directly affects the quality of product.The sealing of product is also just difficult to ensure, affects sealing effectiveness.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of measurement mechanism of three-eccentric-butterfly-valve O-ring seal is provided, solves the problem that O-ring seal measuring error is bigger than normal, measure accurately simple, sealing effectiveness can be ensured well.
According to technical scheme provided by the invention, the measurement mechanism of described three-eccentric-butterfly-valve O-ring seal, feature is: comprise the clamp body be arranged on vertical car, and the centre of gyration of clamp body overlaps with the centre of gyration of vertical car; In described clamp body surface thereof, positioning body is installed, clamping workpiece on positioning body; At the centre of gyration installation bridge of described clamp body, at the upper horizontal of gauge rod frame, gauge rod is installed; The angle formed between two sides of the axial section of the workpiece after processing is divided equally by the centre of gyration of described clamp body, form angle between the centre of gyration of described vertical car and the vertical center line of workpiece, this angle equals the angle formed between the centre of gyration of vertical car and butterfly valve pipe laying center line; One end overhang bridge of described gauge rod, the end of gauge rod external part is the tool setting point of vertical car lathe tool.
Described positioning body is circular, and form boss in the upper surface of positioning body, the lower end, outside of boss is the carrying plane vertical with boss.
Described clamp body is H for installing the length of the installed surface of positioning body, and the plane of this installed surface and the clamping workpiece on positioning body is parallel, and the length of workpiece axial section is L2, and L2 > H.
The measurement mechanism of three-eccentric-butterfly-valve O-ring seal of the present invention solves O-ring seal measuring error problem bigger than normal, by transforming the actual, measured dimension measurement of gauge rod extension elongation being ensured to O-ring seal, measuring accurately simple, ensure that sealing effectiveness well.

Embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1 to 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 be arranged on vertical car, the centre of gyration of clamp body 1 overlaps with the centre of gyration of vertical car; In described clamp body 1 surface thereof, positioning body 2 is installed, clamping workpiece 3 on positioning body 2; At the centre of gyration installation bridge 4 of described clamp body 1, at the upper horizontal of gauge rod frame 4, gauge rod 5 is installed;
Described workpiece 3 is arranged on positioning body 2 with certain angle, and the lathe tool of vertical car is processed workpiece 3, and what obtain after processing is 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 described workpiece 3 obtains after processing is 2 β, the centre of gyration of described clamp body 1 is the angular bisector of angle 2 β formed between two sides of the axial section of the rear workpiece 3 of processing, form angle α between the centre of gyration of described clamp body 1 (i.e. the centre of gyration of vertical car) and the vertical center line (i.e. the vertical center line of workpiece 3) of positioning body 2, the angle formed between the centre of gyration of this angle α and vertical car and the center line of butterfly valve pipe laying is consistent; One end overhang bridge 4 of described gauge rod 5, the end of gauge rod 5 external part is the tool setting point of vertical car lathe tool, and the length of gauge rod 5 external part is L1, and the length L1 of this external part is by the geometric relationship of clamp body 1 and workpiece 3, directly measure from AutoCAD figure and obtain, to guarantee the size L2 of workpiece 3;
As shown in Figure 2, described positioning body 2 is in circular, and form boss 6 in the upper surface of positioning body 2, the lower end, outside of boss 6 is the carrying plane 7 vertical with boss 6; When clamping workpiece 3, boss 6 is positioned at the inner side of workpiece 3, and carrying plane 7 coordinates with the lower surface of workpiece 3, for supporting workpiece 3;
Described clamp body 1 is H for installing the length of the installed surface of positioning body 2, the plane of this installed surface and the clamping workpiece 3 on positioning body 2 is parallel, the length of workpiece 3 axial section is L2, and L2 > H, can prevent vertical car lathe tool from encountering fixture like this.
The course of work of the present invention: angularly α clamping is on positioning body 2 by workpiece 3, and the angle of the center line of this angle [alpha] and the centre of gyration of vertical car and the pipe laying of butterfly valve is consistent; The length L1 of gauge rod 5 external part is determined by the geometric relationship of clamp body 1 and workpiece 3, and directly measures by AutoCAD; During processing work, the lathe tool of vertical car is to the tool setting point of good gauge rod 5, and the workpiece 3 processed is exactly required size L2.
