Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
Embodiment:
As Figure 1-5, the special jaw of a kind of valve opening processing, including left claw 1, right pawl 2, top pawl 3, described left claw 1 is identical with the structure of right pawl 2；Described left claw 1 includes that segment pawl 12 in the first outer segment pawl 11, first, the Inner arc side of described first outer segment pawl 11 are provided with circular arc projection 13；In described first, the external arc of segment pawl 12 matches with the Inner arc of the first outer segment pawl 11, the Inner arc of described first outer segment pawl 11 is identical with the arc length of the external arc of segment pawl 12 in first, and in first, segment pawl 12 is provided with angular protrusions 14 near the side of circular arc projection 13；Described top pawl 3 includes segment pawl 32 in the second outer segment pawl 31 and second, and the external arc of segment pawl 32 matches with the Inner arc of the second outer segment pawl 31 in second, the Inner arc of described second outer segment pawl 31 is identical with the arc length of the external arc of segment pawl 32 in second；Described first outer segment pawl 11 is identical with the outer arc radius of the second outer segment pawl 31, and described first outer segment pawl 11 is identical with the inner arc radius of the second outer segment pawl 31；In described first, segment pawl 12 is identical with the outer arc radius of segment pawl 32 in second, and in described first, segment pawl 12 is identical with the inner arc radius of segment pawl 32 in second.
When being embodied as, wherein ball valve part 4 is as shown in Figure 6, the present invention is fixedly installed on the scroll chuck of lathe by the way of being spirally connected or welding respectively, the profile of ball valve part 4 is to be combined by three cuboids, the hole wanting working position is at maximum cuboid position, four seamed edges at this position have all carried out rounding process, therefore utilize self-centering principle, i.e. left claw 1, right pawl 2, the mode pushing up pawl 3 tangent with the fillet seamed edge of ball valve part 4 positions and clamps, and left claw 1, right pawl 2 is tangent with the two of ball valve part 4 seamed edges respectively, top pawl 3 is tangent with the another two seamed edge of ball valve part 4, segment pawl 32 coplanar in segment pawl 12 and second in first, it is affixed with the bottom surface of ball valve part 4 and axially positions；Meanwhile, the structure of left claw 1 and right pawl 2 limit ball valve part 4 along the axial rotation of lathe main, under above-mentioned common effect, limit the six-freedom degree of ball valve part 4, it is achieved the location completely of ball valve part 4.The present invention is by left claw 1, right pawl 2, the combined groove structure formed of top pawl 3, self-centering feature with the scroll chuck of lathe, i.e. left claw 1, right pawl 2, top pawl 3 is spirally connected respectively with the three-jaw on the scroll chuck of lathe respectively or welds, ball valve part 4 is made to position completely and reliable grip, the hole making ball valve part 4 is coaxial with lathe spindle, thus the hole of ball valve part 4 can be processed by numerically controlled lathe.
