Abstract
The invention discloses a positioning welding mechanism for a multi-claw stainless steel handrail. The positioning welding mechanism comprises a hollowed profile-welded bottom frame, all-directional casters are arranged at the bottom of the bottom frame, a coupling controlled by a gear motor is installed at the frame end of the bottom frame, a bracket where the handrail is placed is arranged on the bottom frame, and positioning pieces used for fixing the handrail are arranged on the bracket. According to the hollowed profile-welded bottom frame, braking and all-directional moving can be completed through the four all-directional casters at the bottom corners. Because the coupling controlled by the gear motor is installed at the frame end, the whole upper mechanism to which the handrail is fixed can turn over by 360 degrees conveniently, and welding can be performed conveniently in all directions. The positioning pieces used for fixing the handrail fix the handrail in a three-dimensional mode, and therefore deformation, in welding and after welding, of the handrail is reduced to the maximum degree. Frame fixing holes and support fixing holes are adjustable oblong holes, and therefore installation of the handrail before welding can meet the size required by a drawing.
