High-dexterity three-dimensional curved surface welding robot device

Abstract

The invention discloses a high-dexterity three-dimensional curved surface welding robot device. The high-dexterity three-dimensional curved surface welding robot device comprises a lifting platform car, a shoulder joint module, an elbow joint module, a wrist joint module, a visual unit, a ranging unit and a welding gun. The shoulder joint module is fixed to the lifting platform car, the elbow joint module and the shoulder joint module are fixedly connected, the wrist joint module and the elbow joint module are fixedly connected, and the visual unit, the ranging unit and the welding gun are allfixed to the wrist joint module. The lifting platform car is a lifting platform driven by a motor, and an upper platform of the lifting platform is a working platform. A high-dexterity mechanical armprovided with the electric welding gun is reasonably combined with the lifting platform car, the beneficial effects of the lifting platform car and the high-dexterity mechanical arm are fully exerted, the beneficial effects of being large in working space, flexible in motion, high in motion precision and the like are achieved, workpieces with large space complex curved surface characteristics canbe welded, and large equipment can be intelligently and efficiently welded at high quality.

Description

technical field [0001] The invention relates to the technical field of robot three-dimensional curved surface welding, and more specifically, relates to a high-dexterity three-dimensional curved surface welding robot device. Background technique [0002] The 3D curved surface welding robot is a device that realizes robot intelligent welding of complex 3D curved surfaces. 3D curved surface welding is very important for the manufacture of large-scale ship hulls, aircrafts, pipelines and other equipment. With the wide application of welding technology, its curved surface welding equipment has also been obtained. to the development. [0003] At present, most welding robots use serial five-axis or six-axis robots. Due to the limitation of their working space, they cannot complete the welding tasks of complex three-dimensional curved surfaces, and most of the welding robot devices are fixed devices, which are limited by the length of the mechanical arm. The application range is s...
