B. Base Tool Changer
QC-18—Electric Tool Changer

1.  Product Overview

The QC‑18 Electric Tool Changer consists of a Master plate assembly and a Tool plate assembly.

CAUTION: 

Do not use the QC-18 Tool Changer in an application where water is present 

or other fluids are being passed. Using the QC-18 Tool Changer in an application where 
water is present or other fluids are being passed, can cause injury to personnel and 
damage to equipment. 

1.1  Master Plate Assembly

The Master plate assembly includes an anodized aluminum body, a hardened stainless steel locking 
mechanism, and hardened steel alignment pins. The Master has (4) Flats, Flat A is specifically for mounting 
the servo motor module. Flat C supports both K series modules and optional modules with J16 mounting 
patterns. Flats B and D support optional modules with J16 mounting patterns.

The servo motor module has an integrated controller and high torque motor (refer to 

Section 1.3—Servo 

Motor Module

 for more details).

A PNP DC proximity sensor is designed into the body of the Master plate to verify Tool plate presence when 
coupled. The sensors provide a ready to lock (RTL) signal through the control module.

RTL Proximity Sensor

The Master provides a mounting pattern with (2) dowel pins for locating the Master and includes (4) 
mounting fasteners (M4 socket head cap screws) (refer to 

Section 8—Drawings

 for mounting details).

PNP DC Proximity sensors are designed into the body of the Master plate to verify the lock/unlock position 
of the locking cam. The sensors provide the Lock and Unlock (L/U) signals through the motor controller 
(refer to 

Figure 1.2

).
