Described manipulator beam lifting and flexible employing driven by servomotor, by digital control system control,
Coordination is overturn with seat positioner end to end.
Described pneumatic drawstring is arranged in the middle part of each melon lobe, for longitudinally pneumatic drawstring.
The beneficial effects of the present invention is: the present invention uses air bag finger tip mechanism workpiece pressing, and thrust is big
Little adjustable, each finger tip can self adaptation workpiece configurations, belong to Compliant pressure, it is ensured that can workpiece pressing,
The most not disfiguring workpiece surface.8 melon lobes respectively increase a pneumatic drawstring of longitudinal direction, can effectively prevent workpiece from becoming
Shape and dislocation.Employing numerically controlled automatic welds, it is achieved that the input of welding process heat is consistent, reduces welding
Deformation greatly reduces labor strength simultaneously, improves production efficiency, it is ensured that welding quality.
