Apparatus for actuating a suction workholder |
摘要 |
An improved apparatus for actuating a suction workholder having a hollow piston slidably mounted in a hollow cylinder. A suction cup is mounted on a distal end of the piston and is in pneumatic communication with a proximal end of said piston via the interior of the piston. A housing defining a vacuum plenum is so attached to the cylinder as to permit pneumatic communication between the plenum and the proximal end of said piston. The improvement resides in a unique positioning of ports and apertures which create pneumatic pressure differentials causing movement of the piston. The use of a biasing spring is not required.
