Clamping device for machining of thin-wall part

Abstract

The invention belongs to the technical field of machined parts, and particularly relates to a clamping device for machining of a thin-wall part. Multiple inner claws are glidingly connected inside a main body; each inner claw can slide in the radial direction of the main body; the outside of the main body is glidingly connected with multiple outer claws corresponding to the inner claws; each outerclaw can slide in the radial direction of the main body; and the right end of an inner claw pulling rod is sleeved with an outer claw pulling rod; the right end of each inner claw is connected with one slope at the left end of the inner claw pulling rod in a matched manner, so that the inner claw can slide along the slope at the left end of the inner claw pulling rod; the right end of each outerclaw is connected with one slope at the left end of the outer claw pulling rod in a matched manner, so that the outer claw can slide along the slope at the left end of the outer claw pulling rod; andpressure sensors are arranged on the inner claw pulling rod and the outer claw pulling rod respectively. The technical problems that a revolving body thin-wall part is prone to deformation in the clamping process and the part falls off due to the insufficient clamping force can be solved.

Description

technical field [0001] The invention belongs to the technical field of processing parts, and in particular relates to a clamping device for processing thin-walled parts. Background technique [0002] Turning of thin-walled parts is often encountered in the processing of rotary parts. At present, there are three main clamping methods used for processing thin-walled parts: [0003] The first is to turn the chuck jaws into the shape of the desired clamping position, maximizing the contact area between the part and the jaws to reduce clamping deformation. The problem with this clamping method is: the turning chuck grip can reduce the problem of clamping deformation, but it cannot be completely avoided. And the jaws after turning are only suitable for the processing of one kind of parts. [0004] The second is to use a pressure plate to compress in the vertical direction of the thin wall, and the pressure does not directly act on the surface of the thin wall to reduce deformati...
