The Automated Socket Changer is developed to meet customer's demands so that sockets can be changed automatically for auto-stations. The system consists of a tool adapter, a socket changer body, a socket dock, two sensors and a sensor mounting bracket.
The tool adapter is attached to a spindle, preferably QST, but others can also be used. The tool adapter has a guided pocket to reduce the system radial play. Every spindle is equipped with one adapter, which is fix-mounted on it. The spindle will pick-up a socket changer with a tool adapter. The whole system can have an infinite number of socket changers as long as the motion unit, such as a robot, can reach where socket changers are placed.
The socket changer works similarly to a manual socket changer. The outer ring can move up and down to activate the lock mechanism inside. Once the outer ring is pushed upwards, an adapter can drive in full. Once the outer ring returns back to the initial position, the adapter will be locked in position. The socket or bit will be attached to the lower part of the socket changer. The socket changer is a common component. Different sockets or bits can be attached as long as they have the same connector size.
The socket dock is mounted at a fixed location and can hold a socket changer in position when it is not in use. It is strongly recommended to mount the dock horizontally for easier programming of the robot movement.
The socket or bit is the required tool to perform the screw or nut tightening process. The sockets or bits are attached to the socket changer. Every socket or bit needs a socket changer. The change of one socket or bit means the change of one socket or bit together with one socket changer.
The sensor 1 will detect if there is a socket changer on the dock.
The sensor 2 will detect if the tool adapter is fully engaged. Only a fully engaged tool adapter can perform the pick-up process correctly.
