Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-6, a fixture for turning thin-wall flanges comprises a motor 4, a chuck 1 and three fixing pieces 16;

the motor 4 is arranged on the lower surface of the chuck 1, a rotating shaft on the motor 4 is fixedly connected with the chuck 1, and the chuck 1 is driven to rotate by the motor 4;

the chuck 1 is horizontally fixed at two ends of the cross bar 19 respectively, and three second sliding chutes 2 are arranged on the upper surface of the chuck 1 at equal intervals outwards from the center of the chuck 1;

the three fixing pieces 16 comprise sliding seats 5, arc-shaped supporting plates 10 and limiting pieces; a second sliding block 8 matched with the second sliding chute 2 is arranged at the bottom of the sliding seat 5, the sliding seat 5 is arranged on the second sliding chute 2 in a sliding mode through the second sliding block 8, a fixing plate 9 is horizontally arranged on the outer side surface of the sliding seat 5, and the arc-shaped supporting plate 10 is horizontally fixed on the fixing plate 9 through welding; a fixing part 6 is arranged on the inner side surface of the sliding seat 5, a jackscrew 7 matched with the second sliding chute 2 is arranged on the fixing part 6, and when the sliding seat 5 slides to a designated position, the fixing part is fixed through the jackscrew 7; the top of the sliding seat 5 is provided with a threaded through hole 15; the limiting piece comprises a screw rod 11, a handle 13 and a limiting block 12; the screw rod 11 is in threaded connection with the threaded through hole 15 on the top of the sliding seat 5, the handle 13 is arranged on the top of the screw rod 11, and the limiting block 12 is fixed at the bottom of the screw rod 11.
