Long stroke parallel grippers tackle tough loads
A new line of long stroke parallel grippers features a robust T-slotted jaw design for the toughest loads.
When the jaws are completely opened, the work piece can be freed without having to retract the gripper.
This saves cycle time, as well as the expense of a retraction mechanism or a cylinder.
From a fully open position, the force generated by the jaw tips increases as they near the fully closed position and become self-locking.
Due to the design of the links, a large closing force is generated.
As the jaws open, the mechanism produces significantly greater velocity at the jaw tips than during the closing stroke.
Therefore, if the jaws are long and heavy, a damping device or throttle valve may be necessary for the opening stroke.
Switch-activating cams (trip dogs) on the face of the gripper fingers can be used as open or closed indicators.
The internal linkages are guided by two side plates made from hard anodised aluminium.
As a result, the gripper can handle large side forces.
All units are double acting.
There are two pairs of air fittings on the front side of the gripper.
The front connections are factory-sealed with removable plugs.
Either pair of air fittings may be used, depending on the mounting constraints.
Threaded holes are provided for fastening the proximity switch mounting blocks.
The jaws are made of C45 K steel, whereas all of the body is constructed from high-strength aluminium.
All jaws are hard anodised and nickel-plated for durability and light weight.
