Click the magnifiying glass to search this FAQ by topic, product, or question  -

Are storage racks available?

Contact us to discuss your specific requirements as many storage racks need to be tailored to the application.

Are tool changers available in imperial and metric porting?

Yes.

Are tool changers available in stainless steel?

Yes. Contact us to discuss your specific application environment requirements.

Are tool changers for robots only?

No. Tool changers can be used anywhere that precision, rigid coupling of two components is required.

Can a tool changer be opened manually?

No, air pressure must be applied to the tool changer to separate the two halves from one another.

Can I swap out utility modules?

Yes, tool changers have a common mounting pattern for utility modules. They can easily be changed in the field when retooling your robot.

Do tool changers have failsafe features?

Yes. A spring in the piston keeps the tool changer locked securely even with loss of air pressure.

Do tool changers have standard ISO mounting?

Tool changers do follow the ISO standard, however many robot manufacturers have mounting with slight variations to this standard. Adaptors are available.

Does the ARV Venturi have a ‘Vacuum Lock’ feature?

No.

How are the utilities mounted to the tool changer?

Utilities are modular, mounting to the sides of the tool changer robot half and tool half.

How many air lines are required to operate a TPLP magnet?

One compressed air line. The magnet is free floating and will engage the part and the air line is used to release it.
