Flexible main splicing system for automobile manufacturing production line

Abstract

The invention discloses a flexible main splicing system for an automobile manufacturing production line, and uses for automatically welding white bodies with different vehicle types. The system comprises a reciprocating lever type body carrying system, side wall splicing subsystems are arranged on two sides of the reciprocating lever type body carrying system, a complex robot welding subsystem isarranged above the reciprocating lever type body carrying system, and a clamp storage subsystem is arranged on one side of each side wall splicing subsystem. The main splicing system is applicable toautomatic splicing and welding of multi-type white bodies, automation is achieved, a robot is designed in an overhead manner, effective space above the system is sufficiently utilized, working space of a plurality of robots is met, the space distances among the robots and welding points are effectively shortened, standard robots with low manufacturing cost are used, lengthened custom-made robots with high manufacturing cost are omitted, the system is provided with the clamp storage subsystems, stations on two sides of the line are sufficiently utilized, a switching stroke of a clamp is shortened, and the space utilization rate of two sides of the line is increased.

Description

technical field [0001] The invention relates to the technical field of body-in-white assembling and assembling, in particular to a flexible main assembling system of an automobile manufacturing production line. Background technique [0002] When performing body-in-white main assembly, the side panel assembly needs to be moved to the main body assembly station for welding and assembly with the lower body. In order to realize multi-vehicle production on the same line, multiple models can be switched freely, and the main assembly system often needs to be equipped with multiple flexible welding robots to match the side wall fixtures of different models, and a fixture library for storing side wall fixtures. [0003] In this way, the main assembly system needs a larger space. In the case of insufficient space, the number of robots and the fixture library can only be sacrificed. On the one hand, the workload of a single robot increases, the working time increases, and the welding...

Problems solved by technology

[0003] In this way, the main assembly system needs a larger space. In the case of insufficient space, the number of robots and the fixture library can only be sacrificed. On the one hand, the workload of a single robot increases, the working time increases, and the welding efficiency is reduced. On the other hand, the types of fixtures that can be equipped with the fixture library are limited, and the flexibility of the main assembly system is insufficient
