Design Considerations
Do not use the plunger to lift loads, or support side loads. The support plunger must always be protected against penetration of contaminants by the plastic plug furnished or a contact bolt (order separately). When supporting underneath a clamp, use a Sequence Valve to delay clamping until the Work Support has reached sufficient load capacity to resist the clamping force. Support load capacity should be at least 2 times clamping force at all times, to resist not only static clamping force, but also dynamic forces due to clamping-arm momentum and machining forces.
| Support Action – Spring Extended
The threaded-body Work Supports shown here have high load capacities, yet are amazingly compact. Manifold mounting capability allows space-saving low-height installation. Available in three sizes, inch or metric threads, with the following load capacities at 7250 psi: 3800 lbs, 9400 lbs, and 23000 lbs.
Plunger is normally extended by light spring force. When the workpiece is loaded, its weight depresses the plunger to the proper height. When fluid pressure is applied, the precision sleeve grips the plunger, locking it securely. Locking height is repeatable within +/-.0002″. Such excellent repeatability is possible because of two design features: 1) a precision sliding-fit pressure sleeve holds the plunger absolutely vertical even while unlocked, avoiding any inaccuracy due to locking a tilted plunger, and 2) locking force is entirely radial, so the plunger remains absolutely stationary during the locking process. |
Support Action – Fluid Advanced
Fluid-advanced Work Supports provide extra loading clearance and are ideal for workpieces that are too light to depress a spring-loaded plunger. The threaded-body Work Supports shown here have high load capacities, yet are amazingly compact. Manifold mounting capability allows space-saving low-height installation
Plunger is normally retracted for clear workpiece loading and unloading. Applying fluid pressure gently advances the plunger to the workpiece, where it contacts with light spring force. As fluid pressure increases, the precision sleeve grips the plunger, locking it securely. The plunger retracts again when pressure is released. Locking height is repeatable within +/-.0002″. Such excellent repeatability is possible because of two design features: 1) a precision sliding-fit pressure sleeve holds the plunger absolutely vertical even while unlocked, avoiding any inaccuracy due to locking a tilted plunger, and 2) locking force is entirely radial, so the plunger remains absolutely stationary during the locking process. |
Support Action – Air Advanced
Air-advanced Work Supports allow fine-tuning contact force using a Fine Air Pressure Regulator, and provide separate control of plunger advance. The top-flange version shown here allows space-saving low-height installation using either standard fittings or manifold mounting. These supports have high load capacities yet are extremely compact and easy to install.
Plunger is normally retracted for clear workpiece loading and unloading. Applying air pressure gently advances the plunger to the workpiece, where it contacts with light force. A Fine Air-Pressure Regulator, Air Extractor Dryer, and Air Clamping Valve are required for air control (see Related Products below). Fine-tune contact force using the air regulator. When fluid pressure is applied, the precision sleeve grips the plunger, locking it securely. The plunger retracts again when fluid pressure and air pressure are released. These Work Supports can also be used as “Air Extended” supports by leaving air pressure constantly on. Locking height is repeatable within +/-.0002″. Such excellent repeatability is possible because of two design features: 1) a precision sliding-fit pressure sleeve holds the plunger absolutely vertical even while unlocked, avoiding any inaccuracy due to locking a tilted plunger, and 2) locking force is entirely radial, so the plunger remains absolutely stationary during the locking process. |
