Robot Tool Changers
A robot tool changer lets one robot use several end effectors: a gripper for loading, a vacuum tool for sheets, a deburring spindle for finishing. The HITREE HQ series robotic quick changer locks the tool plate pneumatically and passes air and electrical signals through to the tool.

Robot Tool Changers range
Robotic quick changers that swap grippers and vacuum tools in seconds, with fail-safe locking and air and signal pass-through.
Robot side (master plate)
Mounts on the robot flange and holds the pneumatic locking mechanism.
Tool side (tool plate)
Mounts on each end effector. Light and low-cost, so you can keep one on every tool.
Signal modules
Electrical contact modules pass sensor and valve signals from the robot to the tool.
Tool stands
Docking stations that hold the tools in a fixed position while they are not in use.

Why choose HITREE HQ series
Fail-safe locking
The locking mechanism keeps the tool attached if air pressure drops.
Lock and unlock sensing
Sensors confirm the lock state before the robot moves.
Air pass-through
6 to 8 air passages feed grippers and vacuum ejectors on the tool.
Hardened locating pins
Precision pins and hardened steel locking parts keep repeatability over long service life.
Typical applications
- Multi-product machine tending cells
- Switching between gripper and vacuum tools
- Welding torch and sensor changes
- Flexible assembly lines
How to choose
- Payload and moment
Add tool mass and part mass, and check the moment from the center of gravity offset.
- Utilities
Count the air lines and electrical signals each tool needs, then choose the module combination.
- Tool storage
Plan tool stands and the robot path so the robot can drop off and pick up tools safely.
Robot Tool Changers: common questions
What is a robot tool changer?
It is a two-part coupling, with a master plate on the robot and a tool plate on each end effector, that lets the robot lock and release tools automatically.
What happens if air pressure is lost?
HQ tool changers use a fail-safe locking design, so the tool stays locked to the robot when supply pressure is lost.
Can electrical signals pass through the tool changer?
Yes. Add a signal module to both sides to pass sensor and valve signals to the tool.
Is it compatible with my robot?
Adapter plates are available for ISO 9409-1 robot flanges. Tell us your robot model when you ask for a quote and we will confirm the fit.
