Problems solved by technology
[0002] Due to the characteristics of large size, large mass, and thin wall of large thin-walled barrel parts, the amount of material removal is often large, and the requirements for wall thickness consistency are high. The stress release is accompanied by the processing process, which makes the processing easy to deform and the wall thickness Poor precision, machining chatter, etc. have become the manufacturing problems that have always plagued this type of large thin-walled cylindrical parts
[0003] The traditional method mainly reduces the amount of processing, multiple small cuttings to control deformation, reduce chatter, low processing efficiency and long cycle time

Embodiment Construction
[0023] Aiming at the problems of serious processing deformation, poor wall thickness uniformity and difficult control of precision of large thin-walled cylindrical parts, the present invention proposes a special pneumatic flexible fixture for large thin-walled cylindrical parts, which provides auxiliary support on the outer surface of the cylindrical parts. The tooling pressure plate adopts a floating structure, which can stably adjust the pressure within a certain range. The position and direction of the pressing block can be automatically adjusted within a certain range, and the actual support position can be automatically adjusted according to the deviation of the parts after deformation, so as to ensure that the support block and the Part contact is effective and reliable.
[0024] On the one hand, the tooling can improve the rigidity of the process system and improve the deflection and deformation of the barrel parts caused by the original cantilever clamping. On the other...

The invention discloses a pneumatic flexible clamp suitable for deformation control of large thin-wall barrel segment part machining. The clamp comprises a bottom plate, a gas cylinder seat, a slidingblock, a lever gas cylinder, a press plate, a gas cylinder, bevel gas cylinder cushion blocks and a middle gas cylinder cushion block. The bottom plate is fixedly connected with the gas cylinder seatthrough screws, and the gas cylinder is connected with the gas cylinder seat, the bevel gas cylinder cushion blocks on the two sides and the middle gas cylinder cushion block. The lever gas cylinderused for fixedly clamping a thin-wall barrel segment part is mounted at the tail of the clamp and is connected with the press plate to be used for pressing the workpiece, and the bottom and the sliding block are connected to be fixed to the bottom plate together through screws. According to the special flexible clamp, ascending and descending and supporting force of the gas cylinder can be adjusted according to the position needing to be supported and the supporting force, the clamping state of the workpiece is effectively guaranteed, machining deformation and clamping deformation of parts ofthis kind are reduced, the machining precision and quality of products are improved, and production cost is saved.
