Described tensioner movable axis piece is 4, and 4 tensioner piston block surfaces constitute cylinder, and its center constitutes the square cylinder cavity.
Described cylinder body is square cylinder body, and square cylinder body is built in the square cylinder cavity, and the airtight respectively piston bush that is fixedly connected with on 4 of square cylinder body is provided with the piston that is mated in the piston bush; Simultaneously, at this outside face and the staggered key bar that is fixed with of piston of every of square cylinder body; Tensioner movable axis piece is connected with 4 of square cylinder respectively, is provided with the guide groove that matches with the key bar at the inside face of tensioner movable axis piece.
Described nut is fixed between the two key bars, and fix screw is connected with nut after by tensioner movable axis piece limiting through hole compression spring.
Described gas is chewed the two ends that are located at cylinder body.
Described every tensioner movable axis piece is airtight vertically to be fixed with four piston bush, is provided with the piston that is mated in each piston bush.
Owing to adopted said structure, the utility model only need be chewed by gas and inject high pressure gas in cylinder body, under the promotion of air pressure, piston outwards moves, promote tensioner movable axis piece and move, thereby the centre hole of chucking roll product unreels with rolling and operates to individual; When needing dismounting, as long as the gas in the cylinder body is emitted.This airpressure axle is in light weight, easy accessibility, not fragile, cost is low.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Shown in Fig. 1 to 5, a kind of piston driving airpressure axle comprises axis body and spindle nose, and spindle nose is fixedly connected on the axis body two ends, and axis body mainly is made up of tensioner movable axis piece 1, cylinder body 6 and piston 4; Tensioner movable axis piece 1 has 4, and its surface constitutes cylinder, and the cylinder center that constitutes at tensioner movable axis piece 1 constitutes the square cylinder cavity.Every tensioner movable axis piece 1 radially is provided with limiting through hole, and this limiting through hole is made up of outer hole and endoporus, and outer aperture is greater than internal orifice dimension.Cylinder body 6 is square cylinder body, is built in the cylindrical cavity of tensioner movable block 1, is respectively equipped with gas for 6 liang at cylinder body and chews 10.Airtightly respectively vertically on the four sides of cylinder body 6 be fixedly connected with four piston bush 5, be provided with the piston 4 that is mated in the piston bush 5.Simultaneously, at the outside face on cylinder body 6 every limits and the staggered key bar 7 that is fixed with of piston.Tensioner movable axis piece 1 is connected with the four sides of square cylinder respectively, is provided with the guide groove that matches with key bar 7 at the inside face of tensioner movable axis piece 1.Airtight seal 2 is established on piston 4 surfaces, and tensioner movable axis piece 1 is supported in the piston outer end.Outside face at cylinder body is fixed with nut, and nut is fixed between the two key bars, and fix screw 9 is connected with nut by tensioner movable axis piece 1 limiting through hole compression spring 8 backs.
