Festo CLR - Function

CLR
4 Festo – CLR – 2017-05e English
2 Function
When the compressed air connections are
pressurized alternately, the piston rod of the
linear-swivel clamp type CLR-... moves in and
out. On the piston rod there is a guide sleeve
with three different grooves. A guide bolt in
the housing grips into the groove. By means
of the special shape of the grooves, the bolt
transfers the following movements to the
piston rod:
– swivel-linear movement of 90° in a
clockwise direction (Bild 2)
– swivel-linear movement of 90° in an anti-
clockwise direction (Bild 3)
– linear movement (with CLR-40-... to
CLR-63-..., see Bild 4).
The piston rod transfers the swivel and linear
movements to the clamping finger. When the
piston rod retracts, the clamping finger
clamps material against a fixed stop. The
end positions are scanned in the sensor
grooves on the cylinder profile.
3 Application
The CLR-... has been designed for friction-locked clamping and holding of
construction parts.
Please note
Torques which affect the internal guide sleeve will damage the CLR-...
S With all assembly work make sure that the maximum torque on the guide
sleeve is not exceeded (see chapter “Mechanical installation”).
