Passenger car assembly method and passenger car assembly line

Abstract

The invention discloses a passenger car assembly method and a passenger car assembly line. Upper stations and lower stations perform operation simultaneously, therefore, damage and aging caused by the fact that parts in a chassis are subjected to coating baking along with a car body assembly are avoided, service life is prolonged, deformation of a casing of a car body caused by welding when the car body and the chassis are fastened is avoided, the rate of finished products is increased, assembly contents of subpackage of the chassis are enlarged, and online assembly time of the chassis is shortened. Modular assembly is achieved by means of subdivision of the technology, operation difficulty of workers is reduced effectively, fund flowing time in production is shortened, and production cost is further reduced.

Description

technical field [0001] The invention relates to an assembly of a passenger car, in particular to a method for assembling a passenger car and a device for realizing the method. Background technique [0002] The body assembly of the car is divided into two types, one is a load-bearing body, and the other is a non-load-bearing body. The non-load-bearing body means that the vehicle has a rigid frame, which is what we commonly call the chassis and the girder. The engine and power part are directly connected to the frame through the suspension, and the frame is connected to the wheels through the front and rear suspension devices. Such a body is resistant to twisting It has high performance and high height, and is generally used for the assembly of passenger cars, trucks or off-road vehicles, but it is clumsy and heavy. The load-bearing body has no frame, only an integral car shell, and all components are installed in the corresponding positions. The load of the body is transmitt...

AI Technical Summary

Problems solved by technology

This assembly method allows the entire chassis to enter the painting workshop. Due to the high temperature in the drying room, the life of the chassis wiring harness and rubber parts will be reduced, and this assembly method needs to complete the chassis assembly, which increases the production cycle of the vehicle.

The body-chassis split type is to weld the body into a hexahedron, fasten it with the assembled chassis after painting, and then connect the chassis to the body by welding. Due to welding stress and heat, the body shell will be deformed, resulting in paint rework , causing great inconvenience to production
