Overview image
This fixture is used both for assembly and presence check of the clip nuts in optical measurement system. Operator loads a CCB part on the fixture and clamps it with 4 clamps. After that fixture is free to assemble clip nuts on the part. While assembling, fixture middle section can be rotated manually to make the assembly work easier and more ergonomic. After assembly is done, middle section rotates back to original position pneumatically for the optical presence check measurement in optical measurement system.

- Retractable pin
- Inductive sensor to detect part
- Clamping points
- Clamp locking cylinder to restrain clamp opening in certain cases
- Manual rotation handle
Pneumatic Rotation
- Bearing (rotation axis)
- Shaft coupling
- Festo pneumatic semi-rotary drive (270 degrees rotation capacity)
- Damper, to limit rotation speed
- Shock absorber to absorb impact energy at the stopper
Other side
Bearing, dampers, shock absorber, clamps, locking cylinder and retractable pin
Fixture in action
Simple simulation of the rotation. With this simulation it was checked that operator can reach all assembly positions easily.
