Hydraulic Work Support
===================================
HYDRAULIC WORK SUPPORT
Hydraulic work support is a hydraulic version
of
a mechanical saew Jack used as a work support element for positively supporting the
workpiece to avoid deformation and minimize distortion and vibration
of
work piece due to cutting and damping forces.
The Hydraulic work support automatically adjusts to the contour of the workpiece, and then locks in position. This support then adds rigidity to
the fiXtured component
to
avoid machining vibrations. They provide either unrested location points
to
the clamps or support to larger or thin
section area of workpiece.
A Type : Spring advance : The spring is used
to
control a contact force when the knocking out
rod
(piston rod) extends
to
a highest knocking–
out position and contacts the workpiece.
B
Type : Hydraulic advance : When the knocking out
rod
is at a lowest position, it is operated by means
of
oil pressure and is knocked out
when being filled with oil and uses a spring to control the contact force with the workpiece.
Mounting method
of
the threaded type Hydraulic Work supports is shown in the mounting diagram below illustrating suggested dimensions of
the cavity to be made in the fiXture. Teflon packing is provided for mounting to avoid oil leakage.
