Abstract

The invention discloses a flexible clamping device and method for turning a thin-wall deep-cylinder stretching part. A main shaft pull rod is movably connected with a flange plate and located in a movable hole, a pressing plate pull rod is fixedly connected with the main shaft pull rod and located above the main shaft pull rod, and a pull claw is detachably connected with the pressing plate pull rod and located between a guide cone and the flange plate. A basic expansion block is movably connected with the guide cone and installed on the outer side wall of the guide cone, the basic expansion block is clamped with the pull claw and located above the pull claw, each plunger expansion block is fixedly connected with the basic expansion block, and the plunger expansion blocks are uniformly distributed on the outer side wall of the basic expansion block at interval. By means of the structure, the principle that single power drives double mechanisms to move at the same time and the characteristic of flexible change of ball plungers are utilized, turning after stable clamping of the thin-wall deep-cylinder stretching part is guaranteed, and therefore parts with large deformation can be machined.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a flexible clamping device and method for turning thin-walled deep tube drawing parts. Background technique [0002] When processing thin-walled deep-tube drawing parts, there are dual problems of stress concentration and stress release in thin-walled deep-tube drawing parts. The outer wall turning fixture mainly has two clamping methods. First, ordinary three-jaw clamping of the outer circle; second, inner To support the inner circle of the part, both clamping methods require that the part will not deform or have a small amount of deformation during the clamping process to ensure that the size of the part is stable after processing. At present, the popular clamping method at home and abroad is to use the second clamping method , through the form of inner support to stably clamp parts with relatively high rigidity for processing, but for parts with large deformation...
