Abstract

The invention discloses a thin-walled revolved body structural part inner hole stiffness improvement device. The thin-walled revolved body structural part inner hole stiffness improvement device comprises a disc (1), top pillars (2), springs (3), radial thrust shafts (4), a first pin (5), a handle (6), a second pin (7), a bolt (8), a nut (9) and an axial thrust shaft (10). The top pillars (2), thesprings (3) and the radial thrust shafts (4) are mounted in a stepped through hole in a cylindrical face of the disc (1). The handle (6) is mounted on the disc (1) through the first pin (5). The axial thrust shaft (10) makes contact with slopes of the radial thrust shafts (4). The other end of the second pin (7) mounted on the axial thrust shaft (10) is mounted in a waist-shaped groove of the handle (6), and the handle (6) is fixed through the bolt (8) and the nut (9). The multipoint supporting adjustable inner hole stiffness improvement device is adopted, the tool universality is improved, and the machinable area of an inner hole stiffness improvement process method is also enlarged.

Description

technical field [0001] The invention relates to a device for strengthening inner holes of structural parts of a revolving body, in particular to a device for reinforcing inner holes of structural parts of a thin-walled revolving body. Background technique [0002] The thin-walled rotary structural part is a rotary structural part with a diameter-to-wall thickness ratio of not less than 20. When turning the outer circle and end face, the inner hole is generally used as the positioning and clamping reference, and the inner expansion mandrel is usually used. The tooling supports the inner hole of the thin-walled rotary structure. This clamping method increases the contact area when the part is clamped, controls the elastic deformation of the clamping, and can obtain sufficient clamping force. Therefore, in the turning process Get a wide range of applications. [0003] However, there are the following problems in the use of tooling such as internally expanding mandrels used in ...
