Claims

[Scope of utility model registration request]

In machine tools, a drive device that moves the center of the tailstock forward and backward, a center position detection device that detects the axial position of the center and sends out a center position signal, a measuring device that sends out a contact signal when it comes into contact with a workpiece, A drive device that moves the measuring device forward and backward relative to the workpiece;
A measuring device position detection device detects the position of the measuring device when moving forward or backward and transmits a measuring device position signal, and each of the above signals is inputted, calculates the length of the workpiece from the center position signal, and outputs a contact signal and a measuring device position signal. This automatic workpiece identification device consists of a control device that calculates the diameter of the workpiece based on the length and diameter, and determines the type of workpiece based on the length and diameter.
