Biaxial portal workstation for driving welding robot

Abstract

The invention relates to a biaxial portal workstation for driving a welding robot. The biaxial portal workstation comprises a portal frame, an X-axis driving component and a Z-axis driving component, wherein the portal frame is formed by a cross beam and upright posts located on both sides of the cross beam, the X-axis driving component comprises an X-axis driving motor, an X-axis driving gear is installed on an output shaft of the X-axis driving motor, and an X-direction rack which is matched with the driving gear is arranged on the cross beam; the Z-axis driving component comprises a Z-axis driving motor, a Z-axis driving gear is installed on an output shaft of the Z-axis driving motor, and the Z-axis driving gear is engaged with a Z-direction rack installed on a Z-axis sliding table. The workstation adopts a biaxial portal structure and has the advantages of high structural strength and wide working range; according to the workstation, a symmetrical welding mode can be adopted by the welding robot, so that linear deformation and torsional deformation can be avoided or reduced after welding, the technical requirements can be satisfied after welding, and the welding quality is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of new modes of intelligent manufacturing, in particular to a dual-axis gantry workstation for driving a welding robot. Background technique [0002] With the proposal of the national "Smart Manufacturing 2025", robots are widely used in all aspects of production and life. In the field of industrial manufacturing, the successful application of welding robots can increase labor productivity, stabilize and improve product quality, improve working conditions, and reduce production. It occupies an area, reduces production costs, shortens the production cycle, ensures production balance, and has significant economic benefits. However, due to the limitation of the working space of the robot, for the robot connection of large and complex structural parts, the capital investment of using a large welding robot is relatively large. At the same time, for some corners, it is difficult for the traditional six-axis robot ...
