Fixture switching for flexible production

The key to the realization of a flexible production line is that the same station can realize the switching of fixtures for different models. In the process of body manufacturing, according to different switching methods, it can be divided into overall switching, partial switching and full servo switching.

Overall switching, the production station has multiple sets of production fixtures, which means that during the production process, a complete set of production fixtures is switched to the production station by means of rotation or movement. There are mainly rotary table switching, movable rotary table switching, and trolley switching.

Partial switching mainly occurs when most of the positioning parts of different workpieces are the same, and only some parts are different. Among modern designs, many market-tested and approved designs can be modularized, which makes full use of the achievements of excellent designs and shortens the development cycle. When the product is replaced, only the local positioning is changed. The corresponding fixtures are only partially changed. In the body production, the floor positioning only needs to switch the positioning of the rear wheel cover, so the main line trolley often performs partial switching at the wheel cover.

Theoretically speaking, a sufficiently fine servo fixture can be applied to various models according to the digital model. The future servo fixture can use one station, reducing the number of trolleys and fixtures, and greatly saving space.
