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

Embodiment 1

[0041] The passenger car assembly method that the present invention proposes, this method comprises following operation steps:

[0042] Firstly, the body shell is prepared, and single-piece blanking is carried out with the help of special processing equipment such as sawing machine, shearing machine, and bending machine, and the body shell of the designed shape is processed.

[0043] Then use the special tire to carry out tailor-welding of large pieces of body frame, the body shell and the frame assembly are fixed, when the body shell is welded, the frame assembly and the left and right sides, the roof frame assembly and the front and rear Welding around the assembly to form a complete hexahedron;

[0044] Then the front suspension assembly, rear suspension assembly, engine assembly and oil and gas pipelines are pre-assembled; the pre-assembly of front and rear suspension assemblies includes the installation of components such as bridges, air suspensions, and stabilizer bars. ...

Abstract

The invention discloses a passenger car assembly line, which adopts simultaneous operation of upper and lower stations, avoids the damage and aging of parts inside the chassis caused by the coating and baking of the body assembly, prolongs the service life, and avoids welding when the body and the chassis are fastened together The deformation of the body shell improves the yield, expands the assembly content of the chassis sub-assembly, and reduces the online assembly time of the chassis; realizes modular assembly through process subdivision, effectively reduces the difficulty of workers' operation; shortens the flow of funds in production time, further reducing production costs.

Description

technical field [0001] The invention relates to a passenger car assembly, in particular to a passenger car assembly line. 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 transmitted to the wheels through the suspension device. The bo...
