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.
