Test Assembly of Automotive Piston Pin Application Example
A retaining ring, called the circlip, is used to assemble the pin that connects the connecting rod and the piston of the engine parts.
Since the circlip is manually assembled, variations will occur. If the circlip is improperly seated in the groove, it becomes a problem in that it ends up falling off later.
The ROBO Cylinder RCP3-TA4R table type was adopted into an automatic inspection machine after the manual assembly which eliminated the circlip failure.
The circlip is now inspected for being at the correct position at the assembly stage. It can be double checked using the zone output signal and the position complete output signal to confirm whether the circlip is positioned within the tolerance range.
