Claims

[Scope of utility model registration request]

A main shaft fixed position control mechanism for clutching a main shaft of a machine tool and a motor shaft that rotationally drives the main shaft, comprising: a main shaft position detecting means for detecting a clutch pawl position of the main spindle; and a clutch pawl position of the motor shaft. A motor shaft position detection means is provided for detecting the position of the main shaft, and a detection signal detected by the main shaft position detection means and a detection signal detected by the motor shaft position detection means are used to match the clutch pawl positions of the main shaft and the motor shaft. What is claimed is: 1. A fixed position control mechanism for a main shaft, comprising: a position control device for controlling a main shaft;
