AI Technical Summary

Technical Problem

The processing and clamping of composite material cylinders in the existing technology is difficult, especially the processing and clamping of new types of load-bearing cylinders, and traditional tooling may be too large, leading to operational difficulties.

Method used

The system employs an airbag and a locking mechanism for clamping. The airbag is installed inside the cylinder, and the locking mechanism includes a three-dimensional frame, a fixed top block, and a cylinder-driven top block. The system clamps the cylinder by applying uniform pressure through a pneumatic device, and uses limit blocks and reference blocks to ensure accurate positioning.

Benefits of technology

The tooling design is independent of the cylinder height, which reduces processing deformation and vibration, and improves the ease of operation and processing accuracy.

Abstract

The application provides a processing tool for a composite cylinder and a processing technology thereof. The processing tool comprises a gas bag and a locking mechanism. The locking mechanism is an upper and lower split structure, and the upper and lower locking mechanisms are basically the same. The locking mechanism is a three-dimensional frame as a main structure, and top blocks are uniformly distributed around the center position. The top blocks are divided into fixed type and cylinder pushing type. The locking mechanism is attached with a gas pipe, a pressure gauge and a hand valve. The upper locking mechanism is further provided with a detachable limiting block. The application has the effects of solving the problems of easy deformation of clamping and easy vibration of processing caused by low rigidity of the composite cylinder, and solving the problems of overlarge processing tool for a super-high cylinder and inconvenient operation.
