6 An air flow is generated on the bearing surface via blow-out
bores. This way the clamping ring support is cleaned so that
when a pallet is set down, the flat surface is clean.
7 The clamping slides move outwards and lock the clamping ring
on the pallet in a self-locking form fit.
The clamping rings are centered on the taper surface of the
clamping module.
Lifting and centering function
The quick-change pallet modules NSP 140-A and -AZ have an
optional lifting function (A) for lifting the pallets after opening or
they have a centering and lifting function (AZ). With the lifting
function, the clamping ring is automatically centered during the
locking process and slowly lowered to the bearing surface. The
lifting function is also provided to regulate the air control (see
chapter "Air control and blow-out function for cleaning the flat
surface"
With the centering and lifting function, the fed pallet is pre-
centered by a centering mandrel before the pallet is slowly
brought to the bearing surface.
The base body (item 1) contains an axially movable lifting pin (item
6). The lifting pin is sealed with an O-ring (item 33) against the
ingress of coolant, dust and chips. The lifting function is initiated
and transmitted by the shoulder screw (item 10) which is
connected to the cylinder piston (item 3). The lifting pin is located
inside the clamping ring, so that the pallet is lifted directly at the
lower base side of the pallet.
The maximum permissible lifting force per clamping module is
limited (see chapter "Technical data"
). The
permissible total weight of the device assembly to be lifted on a
clamping module must not be exceeded. A higher weight can lead
to tension when removing the pallet. A malfunction could result
and damage the clamping system. The stroke range of the lifting
pin is max. 5.5 mm.
In locked status, the lifting pin is lowered by 0.1 mm. The lifting pin
is lowered without the need for force to be applied, therefore no
minimum contact weight of the clamping pallet is required.
