Application:
Irregular
job is supported on only three points. If an additional support
is required, it must be adjustable, like the
manual screw jack support. Hydraulic work support is the right
solution for such application. The work support is
used to support the job, to avoid deflection and vibrations due
to cutting and clamping forces. It helps to clamp the
job without distortion. These work supports are mounted directly
in threaded manifold as per drawing. These work
supports are more suitable where space is limited.
Principle
The
plunger is free in the unpressurised mode. It touches the job
either by a light spring force or by pneumatic pressure.
In pressurised mode, it resists to move in the axial direction.
The resistance is equal to the radial inward force multiplied
by the coefficient of friction.
