External clamp for small items and round parts

External clamp design for small items

Two circular clamps are designed to be guided by a housing with a similar profile. Both clamps rotates along the fixed pin while the actuating piston is activated.
A taper tip piston is used to provide a strong clamping force.
To release the clamped part, the piston rod retracts causing the link bars to pull the circular clamps back to its original location, releasing the part.

This design is best used for parts that has a larger variation in outer dimension as the part will always be self aligned to the center of the clamp. 

External clamp design for round items with spring return

This design is similar to the first design, the two clamps is able to immediately return to its original position when the piston rob retracts. This design is more suitable for a cleaner environment where dust and dirt will not affect the clamp to return.
