What is a contact code recognition device for CNC lathes?

The structure of the contact code recognition device of the CNC lathe factory is simple, but the reliability is poor, the life is short, and the tool cannot be selected quickly.

Contact code identification device of CNC lathe factory. Two types of coding rings with different diameters are installed on the tool holder 1. The large-diameter ring indicates a binary “l”, and the small-diameter ring is “.” There are five coding rings 4 in the figure. Tool recognition device 2, extending f {{several contact pins 3. The number of contact pins is equal to the number of coding rings on the tool holder. Each contact pin is connected with a relay. When the coding ring is large, it contacts the contact pin, the relay is energized, and the number is “l”. When the coding ring is small in diameter, it does not contact the contact pin, the relay is not energized, and the number is “.”;

When each relay reads the number of H {and the code of the required tool is consistent, the control device sends a signal to stop the tool magazine and wait for the tool to be changed.
