Problems solved by technology

The stitching between two-dimensional layers of textile composite materials can be realized on general industrial sewing machines. However, for large-scale three-dimensional space-shaped composite material prefabricated products with complex geometries, due to the limitation of sewing angle and equipment flexibility in traditional sewing methods However, it is impossible to use traditional suturing equipment to complete the process at one time

Abstract

The invention discloses an end suturing device for a suture manipulator for composite material and a stitch forming method thereof. The device comprises a framework, a driving mechanism, a needle barmechanism, a thread locking mechanism and a thread conveying mechanism. The driving mechanism provides power. The needle bar mechanism and the thread locking mechanism perform periodic motion to cooperate with each other on the upper surface of sewing material so that sewing operation of a three-dimensional preformed part of textile composite material is achieved. A flange at the top of the framework can be connected with a tail end of a multi-degree of freedom industrial robot. By using pose transformation of the industrial robot, a problem that the position of conventional sewing equipment is limited during processing of the preformed part in the three-dimensional shape. Therefore, flexibility of sewing operation is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of sewing equipment for three-dimensional textile composite material preforms, and in particular relates to an end sewing device of a three-dimensional textile composite material prefabricated sewing manipulator system and a stitch forming method thereof. Background technique [0002] With the development of science and technology, textile composite materials have been widely used in aerospace, automobile and other fields. The stitching between two-dimensional layers of textile composite materials can be realized on general industrial sewing machines. However, for large-scale three-dimensional space-shaped composite material prefabricated products with complex geometries, due to the limitation of sewing angle and equipment flexibility in traditional sewing methods However, it is impossible to use traditional suturing equipment to complete the processing at one time. The use of industrial robots combined wit...
