White car body assembly product line ski reciprocation conveying system branch station lifting mechanism

Abstract

The invention discloses a substation lifting mechanism for a skid round trip conveying system on a sedan white body assembly production line. The invention has a plurality of substation lifting mechanisms with the same structure, and each substation lifting mechanism comprises an erect first steam cylinder (2) under a first mounting plate (7) within a skid (6), an erect second steam cylinder (4) under the second mounting plate (5) inside the skid (6) and a synchronizer (3) which keeps the lifting speed of the first steam cylinder (2) in accordance with that of the second steam cylinder (4). The substation lifting mechanism for the skid round trip conveying system on the sedan white body assembly production line adopts the structure which can reduces the kinetic energy consumption, is convenient to maintenance, and relieves the workload of machine maintenance.

Description

technical field [0001] The invention relates to production line equipment, in particular to a sub-station lifting mechanism of a skid reciprocating conveying system in a car body-in-white assembly production line. Background technique [0002] At present, the skid reciprocating conveying system of the automobile body assembly production line has a lifting device and a horizontal linear conveying device. A skid reciprocating conveying system of a car body-in-white assembly production line has multiple sub-station lifting mechanisms with the same structure, and each sub-station lifting mechanism The sheet metal parts placed on the welding fixture are lifted vertically and separated from the fixture to provide a space reference for the subsequent horizontal linear conveying device; the horizontal linear conveying device is to horizontally convey the sheet metal parts separated from the fixture to the next station to realize flow operation . The working principle of the substat...

AI Technical Summary

Problems solved by technology

With such a structure, since an automobile body assembly production line is often tens of meters or even hundreds of meters long, the automobile body assembly production line is composed of multiple sub-stations, and the lifting mechanism of each sub-station is driven by a unified driving source. There is no difference between front and back, and it has perfect performance in synchronous operation, but its kinetic energy loss is large. When there is a problem with the lifting mechanism of the skid to and fro conveying system at a certain substation and needs to be repaired, the entire production line needs to be involved, making maintenance difficult; In addition, it is necessary to frequently add lubricating oil to the rack and pinion, and the mechanical maintenance workload is large.
