が考えられる。(Prior art) Conventionally, during machining, it was left to the operator's judgment to confirm that the workpiece was attached to a long rotating workpiece holding device from the base end to the workpiece holding tip. This inevitably leads to misjudgments and oversights. Therefore, it is necessary to install a sensor that automatically detects the attachment of the workpiece.
Considering that the work holding device rotates together with the work, it is conceivable to use a proximity switch such as a reed switch.

There has been a problem in that it is difficult to detect that the workpiece has been accurately positioned at the mounting location.

An air supply path is formed to send pressurized air in the axial direction from the part to the tip, and an outlet of the air supply path is provided on the surface where the workpiece comes into contact with the workpiece when the workpiece is mounted, and when the outlet is closed by the workpiece, it rises. An air sensor is provided that can automatically detect that a workpiece to be machined is correctly mounted by detecting the air pressure in the air supply path.

Ｗの装着を検知することができる。First, the tip of the collet chuck 4 is inserted into the inside of the workpiece W to be machined by the action of the rotary cylinder 5, and the workpiece W
When fixing the collet chuck in the mounting position, air is sent from the pressurized air source into the air supply path through the air cylinder 19, and this air passes through the center of the workpiece holding rotary body l and reaches the tip of the collet chuck 4. The exhaust is discharged from the outlet L8, but as the end face approaches to fix the workpiece W, the exhaustion from the outlet 18 is gradually restricted, and when the workpiece W is completely attached as shown in the figure. , the outlet 18 is closed. As a result, the air pressure in the air supply path increases, and by detecting this with, for example, a barometer attached to the air cylinder 19 or the pressurized air source, it is possible to detect the attachment of the workpiece W.
