With
the toggle action principle, quick action clamps offer various
advantages:
.
Clamping
arm comes fully away from the working area and leaves unimpended
access to the fixture.
.
A
slight movement of the control lever brings the clamping arm
near the piece in process.
.
The
force exerted on the clamping arm is monitored by the control
lever.
.
The
maximum clamping force is achieved when the three pivots are
aligned
.
The
intensity of the force exerted on the tool depends upon: the
force applied to the handle; the position of the pressure
spindle in the hold down bar.
.
When
in the closed position the dead point can exceed to a certain
extend. The clamping lever is in over-centred, locked position
with steady and irreversible holding capacity.
.
The
force the clamp may absorb in the closed position with no
permanent deformation is called holding force (Fh). Its amount
is peculiar to each clamping tool and varies according to
each clamping size and form.
.
Clamps
are available with magnetic cylinder.
.
Flanged
washers or bolt retainers are included in the supply.
