During the use, the utility model discloses a press from both sides the process of getting as follows: first, as shown in FIG. 4a, air enters the air guide through hole 8-1 from the air inlet at the outer end of the air guide through hole 8-1 of the air guide rod 8, and due to the action of the return spring 16 in the inner cylinder liner 6, the small piston 14 in the inner cylinder liner 6 exerts pressure on the air guide rod 8, and high-pressure air will preferentially enter the main cylinder barrel 7 from the air outlet hole 8-2 of the air guide rod 8. Because the main shaft connecting cover 9 is fixedly connected with the main cylinder barrel 7, the three positioning blocks 5 which are uniformly distributed along the circumference are fixed on the main cylinder barrel 7, and the inner cylinder sleeve 6 moves along the guide groove 61 on the inner cylinder sleeve 6 under the action of air pressure and the limit of the positioning blocks 5. And since the bayonet mount 17 is fixed to the inner cylinder liner 6, the entire mounting bracket 17 including the claw 1 will also move forward with the inner cylinder liner 6.
Meanwhile, as the stepped structures fixedly matched with the spring hangers 10 are arranged in the through holes of the main cylinder barrel 7 and the counter bores 17-1 of the clamping groove seats 17, one end of each extension spring 22 is arranged on each spring hanger 10 fixed on the main cylinder barrel 7, and the other end of each extension spring 22 is arranged on each spring hanger 10 fixed on each clamping groove seat 17, the extension springs 22 are also extended in the process of extending the inner cylinder sleeves 6, but the inner cylinder sleeves 6 still continue to move outwards due to the existence of air pressure, as shown in fig. 14.
Then, the movement is stopped when the inner cylinder liner 6 moves to the positioning block 5 along the guide groove 22. After the inner cylinder sleeve 6 moves to the extreme position, high-pressure gas does not enter the main cylinder barrel 7 from the gas outlet hole 8-2, but enters the main cylinder barrel 7 from the gas outlet hole at the inner end of the gas guide rod through hole 8-1, the high-pressure gas can enter the inner cylinder sleeve 6 due to the gradual rise of the pressure in the main cylinder barrel 7, the small piston 14 starts to move under the action of air pressure, and the taper rod 15 is fixedly connected to the small piston 14, so the taper rod 15 moves forwards along with the small piston 14.
Then, the movement of the conical head end of the conical rod 15 is performed along the conical surface of the inner side surface of the claw 1, and the claw 1 performs centrifugal movement along the T-shaped groove 17-2 on the clamping groove seat 17 as the movement displacement of the conical rod 15 is gradually increased. The small piston 14 will move to the point of stopping the movement when it contacts the small cylinder cover 3, at which point the overall outer diameter D of the six claws 1 will be maximized to achieve gripping of a paper tube or other workpiece containing an inner bore, as shown in fig. 15.
The utility model discloses a recovery process as follows: the introduction of high-pressure gas is stopped firstly, and because the claw return spring 19 is compressed in the clamping process, no high-pressure gas provides outward moving force for the claw 1 at the moment, and the claw 1 gradually moves towards the circle center of the clamping groove seat 17 under the acting force of the claw return spring 19. In the process of resetting the claw 1, the reset spring 16 provides power for resetting the small piston 14, and the small piston 14 moves away from the small cylinder cover 3 under the action of the reset spring 16 until contacting with the air guide rod 8 as the small cylinder cover 3 is fixed on the inner cylinder sleeve 6 through the stepped limiting structure. Meanwhile, in the process of resetting the claw 1 and the small piston 14, the inner cylinder sleeve 6 as a whole also performs resetting movement along the guide groove 1 under the tensile force action of 6 extension springs 22 uniformly distributed along the circumference until the guide rod 8 is contacted with the main shaft connecting cover 9.
And, the above 3 reset processes (reset process of the claw 1, reset process of the small piston 14, reset process of the inner cylinder sleeve 6) are carried out at the same time, the whole outer diameter D of the claw 1 will gradually decrease in the reset process, when all the claws 1 are reset to the initial position on the slot seat 17, the whole outer diameter D thereof reaches the minimum, and the original clamping part can be taken out at this time. After all the parts are reset, the pneumatic chuck returns to the initial state and is ready for the next round of clamping action.
