Method of operation and use

The clamping unit type HMPL−...−KP blocks
the clamping rod 2 by means of a frictional
connection. The clamping rod is connected
rigidly to the piston rod of the linear module.
A spring in the clamping unit presses two
clamping jaws apart. When the claming jaws
open, they are tilted against the clamping rod.
When the compressed air connection 4 is
pressurized, the clamping jaws are positioned
in relation to the clamping rod so that the
piston rod of the linear module can move
freely. The clamp can be loosened by manual
operation 5.
The clamping unit type HMPL−...−KP is designed for holding the piston rod of a
Festo linear module type HMPL−... , which should preferably be placed in a vertical
position. Clamping the HMPL−...−KP when the piston rod is moving (braking) is not
permitted.
Use of the HMPL−...−KP when there is a sudden drop in pressure in the complete
system is only permitted if the functioning is checked afterwards (see Oper
ation").
With the exception of a sudden drop in pres
sure, clamping may only be carried out in the
end positions of the linear module (e. g. when
the end position has been reached). This is
referred to in the following as the park posi
tion.
The clamped piston rod resting in a park posi
tion may be pressurized only in chamber K
on the stroke side (see Fig. 3).
This is to prevent the piston striking against
an unpressurized chamber when clamping is
released.
