Description

Technical Field

[0001] The utility model belongs to a body-in-white operating device and relates to a flexible tabletop based on the transportation of various vehicle models. Background Art

[0002] The body in white refers to the body after welding but before painting, excluding moving parts such as four doors and two covers; the painted body refers to the body after painting, which includes four doors and two covers; they are all transported off the production line according to demand, mostly by using a transfer vehicle to carry and transport, using the chassis longitudinal beam as the fulcrum, and positioning the positioning holes and pins to achieve the load-bearing, positioning and lifting methods for body transportation; the painted body in white plus the interior and exterior decoration and electronic and electrical systems, plus the chassis system, plus the powertrain system constitute the whole vehicle. Before the tires are installed, if there is a need to transport it off the line during this process, a transfer vehicle is also required to carry and transport it, but the fulcrum of the transfer vehicle used is different from that of the body in white transfer vehicle; at the same time, it involves the switching and replacement of multiple models, resulting in different lengths and widths of the chassis, and at the same time involves different processes of electric vehicles and fuel vehicles. Restrictions such as welding, painting, and assembly workshops require a variety of transfer vehicles to cope with different work needs, resulting in poor connection or waste of production costs; especially in the R&D or trial production departments, the flexibility and versatility of the vehicles are more prominent.
