Novel high-precision movable platform for industrial welding robot

Abstract

The invention relates to a novel high-precision movable platform for an industrial welding robot. The platform comprises a rotary driving device and a six-degree-of-freedom parallel connection mechanism. The six-degree-of-freedom parallel connection mechanism is located below the front end of the rotary driving device, and the rotary driving device is fixedly connected with the six-degree-of-freedom parallel connection mechanism. The movable platform has supporting and position adjusting functions on the welding robot. Load-bearing capacity is high, adjustability is good, movement flexibility is high, the overall position of the robot can be adjusted, local positions are flexible to move, stability is high, and welding quality and efficiency of the welding robot are indirectly improved. The rotary driving device can move left, right, front and back on the horizontal plane and rotate in the vertical plane, that is, the rotary driving device can move in three directions of degrees of freedom including two horizontal movement directions and one rotation direction in space. By means of the rotary driving device, overall large-size and large-azimuth adjustment of the welding robot during welding can be guaranteed, and welding performance of the welding robot is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a novel high-precision mobile platform for welding industrial robots. Background technique [0002] Welding is also known as welding or welding. Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flames, electric arcs, Laser, electron beam, friction and ultrasonic, etc., in addition to being used in factories, welding can also be carried out in a variety of environments, such as the field, underwater and space, no matter where welding may bring danger to the operator, Therefore, appropriate protective measures must be taken when welding. Possible injuries caused by welding include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviolet radiation. For the current we...

AI Technical Summary

Problems solved by technology

For the current welding, manual welding is mostly used, which not only takes up a lot of labor costs, but also has low welding efficiency and poor welding quality, and due to manual welding, dangerous accidents often occur during the welding process, which brings certain personal injuries to welders. At present, welding robots are gradually used to weld workpieces. The current welding robots are generally composed of welding brackets, welding equipment and control systems, but the current welding brackets have poor adjustment, weak carrying capacity and poor movement flexibility. question
