Brief description
The locking mechanism of the tool changing system is realized
over balls. The balls are pressed over a bevel in a receptacle.
With air pressure loss the balls are held in the receptacle by a
spring integrated in the cylinder, whereby an automatic locking is
ensured with decrease of pressure. Contacts fitted with springs
are used for the signal transmission. Thanks to the springs a
bend of the contacts can be avoided. The individual contact pins
can be exchanged individually by a patch cord. Thereby a high
life span and transmission reliability are ensured.

System locked
Power and moment transmission is by means of two generously
proportioned pins that also function as an antitwist protector.
After the system is locked, the TK 35 tool changer system can
transfer 5 pneumatic lines and - with the aid of the plug connect-
ors - 15 electrical signals from the robot side to the tool side.
Tool changer of the TK-series provide a number of benefits:
For fast and problem-free changing from tools and grippers
at robots or gantries up to a payload of 1000kg.
Transmissionof electrical signals by spring fitted contact
pins
Coupling and uncoupling of pneumatic and hydraulic lines.
Specific splash-proof execution (optional)
IP 65 sealed electrical signal transmission (optional)
Tool changer with internal routing (optional)
Stainless steel tool changer (optional)
