Description

Technical Field

[0001] The utility model relates to the technical field of bending machine accessories, in particular to a liftable multifunctional gravity positioning table. Background Art

[0002] In the automated bending production line, the six-axis robot is currently the best solution. In the process of robot bending, due to the inability to fully align the workpieces to be bent during stacking and the diversity of the workpieces to be bent, the robot cannot calibrate the origin of the workpiece coordinate system well, so the worktable that is positioned by the workpiece's own gravity came into being. In actual production, some workpieces are directly cut and stretched by punching machines, so that the workpiece shape has more than one plane, and the workpiece is three-dimensional, so the positioning function cannot be realized for the workpiece; if the positioning function is realized by the traditional disassembly method, the labor intensity of the workers will increase and time will be wasted.
