Automatic tightening system
for door handles
Fiam has designed and manufactured an assembly system to tighten automatically various
types of grub screws on different models of
door handle. The system will be integrated into
a turntable, provided by the customer, with a high
production rate which involves further handle
machining processes to be carried out:

- manual positioning
- drilling
- thread tapping
- grub screw tightening
- manual offloading
The customer required a tightening cycle time of
1 grub screw every 3 seconds.

Two types of grub screw with different sizes:
same diameter M6 and lengths 9 and 12 mm.

This system has an automatic grub screw feeding unit with a single circular feeder enabling to process both
sizes of grub screws.

Each time the grub screw needs to be changed, a quick and easy manual operation will allow to adapt the
feeder in just a few seconds.
