Specifically, main function of the present invention is that the centering for realizing various centrosymmetric tubing different tube diameters clamps；In order to
Meet this demand, a adjustable big stroke of special exploitation is to heart gripping dogs；Main composition is by filling on power voussoir
Cushion block and claw and holding pad etc. form；Can realize air spider ventilation after two opposite side claw make centering synchronous linear fortune
It is dynamic；The various workpiece with different tube diameters substantially symmetrical about its central axis are realized easily（Pipe-type）Clamping and positioning；Claw has that quality is light and handy, is used to
Measure small, the bore passed through is big, easily adjusts, dismounting, it is easy to use stable the advantages that.It is embodied as：Air spider is fitted with
Power voussoir that can be for linear motion；Equipped with an isometric cushion block of ladder on power voussoir, power voussoir side is equipped with fine adjustment block；
Using ladder side isometric on cushion block to keep to the side, claw is loaded onto, and be fixed on power voussoir；Holding pad is mounted in the long end of claw
On；By adjusting the screw in fine adjustment block during assembling, position of four cushion blocks relative to center is adjusted, ensures that circumference bounce exists
In allowed band；Then with positioning pin is beaten, adjust four cushion blocks are fixed on power voussoir；At this time, because cushion block 4
A ladder position is isometric, and 4 claws and holding pad are also all wide, so, with any identical ladder position of cushion block
Side is used as and keeps to the side, and loads onto claw and holding pad, and the holding pad inner side of two opposite side is symmetrical relative to center after assembling；So as to
Realize pipe, even the centrosymmetric tubing such as elliptical tube is self-centering easily and clamps for square tube and rectangular tube；Further, since gas
The power voussoir stroke that dynamic chuck drives is limited, therefore need to adjust the position of step of the claw on cushion block, realizes more Large Diameter Pipeline
Clamping demand；And Large Diameter Pipeline workpiece relative mass also increases, 4 claw footstocks are housed on air spider end face at this time, are utilized
Kidney slot adjust claw footstock to neutrality, certain guiding and branch are played in the clamping to Large Diameter Pipeline workpiece to four claws
Support acts on；The present invention can clamp caliber by 30 ~ Φ of Φ 200（Rectangular tube, rectangular tube and elliptical tube are its minimum inscribed circle diameter）.
The embodiment of the present invention simply introduces its embodiment, does not lie in and limits its protection domain.The skill of the industry
Art personnel can make some modifications under the inspiration of the present embodiment, therefore all equivalence changes done according to the scope of the claims of the present invention
Or modification, belong in scope of the patent claims of the present invention.
