Body shop (automobile production)
As a shell in the area which is automobile production , the process of assembling sheet metal parts from the press plant to the body shell described. In addition, the term is also used to describe the state of the automobile after this process. In English, the term body in white is also used.
description
In the shell construction, the sheet metal parts from the press shop are often connected by spot welding , but also by web welding or pressure joining . Other methods such as riveting (e.g. for aluminum / steel connections) and gluing (to support the welded connections ( spot- welded gluing ) but also as the only connection) are being used more and more often . A large number of industrial robots are typically used in the shell construction .
The body shop in the body shop can be divided into the following seven main groups:
- Floor assembly / engine compartment production
- Sidewall production
- Roof automation
- Doors Street
- Trestle line
- Assembly line
- Finishing tape
In addition, several departments work in peripheral areas:
- Incoming inspection
- Sample inspection
- Quality control
- Material handling and logistics
Specialist departments support production employees in the event of technical faults or quality problems, e.g. B .:
- Central workshops, electrical and mechanical
- Robot workshop
- Pneumatics workshop
- Welding team
- Electronics and networks
- Workshop for industrial trucks
Requirements for the shell
Numerous, partly contradicting requirements are placed on the shell. Direct requirements e.g. B. the position of the natural frequencies are directly influenced by the shape of the body. Indirect requirements, e.g. B. from the requirements for the entire vehicle must be derived from these and transferred to the body. For example, the energy consumption can be positively influenced by lightweight construction measures for the body. According to Braess and Seifert, another way of dividing requirements for the shell construction is the division into customer-relevant and production-relevant criteria.
| High passive safety | Easy to manufacture |
| Low fuel consumption | Low manufacturing costs |
| Great comfort | Easy accessibility (manufacture) |
| High functionality | High process capability |
| High quality | Low use of materials |
| Long life span | Simple assembly sequence |
| Low price | High rigidity |
| Low repair costs | High natural frequencies |
| Low noise level | Low insurance rating |
| High loading volume | High functionality |
| Long range | Light weight |
