Abstract

The invention belongs to the field of mechanical devices, and in particular, relates to a flexible combined clamping device and a clamping method of weak-rigidity composite material parts applied to the field of aerospace manufacturing. The clamping device comprises a combined base, a flexible support system and a positioned pressing device; the flexible support system is mounted on the combined base; the positioned pressing device is positioned above the flexible support system; the flexible support system comprises multiple support units; each support unit comprises a support rod, a vacuum sucker and a spring; two ends of the support rod are respectively connected with the vacuum sucker and the spring; and the vacuum sucker is connected with the support rod through a spherical joint. The clamping device can realize quick clamping of the weak-rigidity composite material parts with different molded surface characteristics, adapts to different shapes and sizes of the parts, greatly improves the flexibility degree of the clamping mode, and is suitable for multi-variety and small-batch production demands.

Description

technical field [0001] The invention belongs to the field of mechanical devices, and in particular relates to a flexible combined clamping device and clamping method for weakly rigid composite material parts applied in the field of aerospace manufacturing. Background technique [0002] Composite materials are composed of two or more different substances, which overcome the defects of a single material and expand the application range of materials. Among them, honeycomb composite materials are typical representatives of weakly rigid composite materials. They originated from bionics and have high compressive and bending strength. High rigidity, ultra-light structural characteristics, and functions such as cushioning, heat insulation, and sound insulation. It was first used in the aerospace field, and then extended to the construction industry, furniture manufacturing, packaging, and transportation industries. It has high economic value and can be recycled, which is conducive to...
