Design and Operating Principle
In body-shop welding and assembly, parts are located on pins and held by clamps while robots weld or join them. Clamps and pins on fixtures and robot end effectors must survive weld spatter, dirt and constant cycling while holding positions precisely.
A shot pin extends into a locating hole to position a part or fixture precisely. Anti-rotation keeps shaped pins oriented, and wipers or scrapers clean the ram to protect bearings from spatter.
Integration and Selection
Select pin and stroke for the locating hole, choose scrapers in heavy spatter areas and add sensors.
Use for fixture or turntable indexing.
