When the fixture is used, the two air holes 113 of the pneumatic driving mechanism 11 are connected with a high-pressure air pipe to provide power air for driving the pneumatic driving mechanism 11, when the high-pressure air enters the pneumatic outer cylindrical shell 111 from one air hole 113, the high-pressure air is filled between the pneumatic outer cylindrical shell 111, the air baffle 112 and the driving plate 115, because the air baffle 112 is fixedly arranged on the inner wall of the pneumatic outer cylindrical shell 111 and cannot move, the high-pressure air pushes the driving plate 115 to rotate by the middle shaft of the first screw rod 2, thereby driving the first screw rod 2 to rotate, simultaneously driving the second screw rod 3 to rotate through the meshing transmission of the first transmission tooth 4 and the second transmission tooth 5, the rotation of the first screw rod 2 and the second screw rod 3 drives the four clamping claws 8 which are in threaded connection with the threads which are oppositely arranged at two sections on the two screw rods to slide in the respective sliding grooves 7 towards the center of the lower cylindrical shell 1, thereby realizing that the four claws 8 move towards the center of the lower cylindrical shell 1 at the same time, keeping the center of the bearing ring at the center of the lower cylindrical shell 1 and the upper cover 9 all the time when the four claws 8 clamp the bearing ring, when the clamped bearing ring needs to be removed, only high-pressure gas is required to be introduced from the other air hole 113 to drive the first screw rod 2 and the second screw rod 3 to rotate in the opposite direction, thereby driving the four claws 8 to move towards the direction away from the centers of the lower cylindrical shell 1 and the upper cover 9, further leading the claws 8 to loosen the bearing ring, respectively driving the first screw rod 2 and the second screw rod 3 to rotate clockwise or anticlockwise through the pneumatic driving mechanism 11 by introducing high-pressure gas from the two air holes 113 to respectively drive the four claws 8 to close or separate so as to clamp or clamp the bearing ring, realizing the automatic operation and control of clamping and releasing the bearing ring, reduces labor intensity and improves efficiency. When the four clamping claws 8 close the clamping bearing ring, high-pressure gas is always filled from the air hole 113, so that the driving plate 115 is always kept at the position in the pneumatic outer cylinder shell 111, the force for driving the first screw rod 2 and the second screw rod 3 to rotate is always kept so that the two screw rods cannot loosen due to vibration and the like, the clamping of the bearing ring is stable, and the size of the holding force can be controlled by adjusting the size of the air pressure.
The stop 114 is provided so that the driving plate 115 does not rotate to the other side of the two air holes 113 and thus the range in which the two screw rods drive the four jaws 8 is too small.
