うに位置検出器を装着する必要が生ずる。-Technical background- This type of position detector generally has a structure that electrically detects the contact between the contact needle and the workpiece.
On machine tools equipped with an ATC (automatic tool changer), the tool is inserted into and removed from the tool mounting hole by the ATC.
Cordless NC (numerical control) of electrical signals during detection
There is a request to input into the device. As a means to meet this requirement, it is possible to adopt a structure in which the detection signal of the position detector is received by the receiving section on the machine tool side via a photocoupler, but in this case, the light emitting element of the position detector is It becomes necessary to mount a position detector so as to face the element.

いこととなる。 To give a specific example, as shown in FIG.
The position detector 14 must be mounted so that the signal transmission section 4 faces the reception section 16 mounted on the spindle casing 15 of the machine tool. When the position detector 14 is mounted by ATC, the direction of the groove 13 provided in the grip part 8 is always constant, so the relationship between the direction of the groove 13 and the direction in which the signal transmission part 4 extends It is only necessary to determine the position according to the mounting position of the receiving section 16 of the machine tool.

できないという問題があつた。-Prior art and problems- However, this positional relationship is not constant for all machine tools, and varies depending on the machine tool manufacturer or model. The relationship between the groove 13 and the extending direction of the signal transmission section 4 also differs depending on each machine tool. For this reason, in conventional position detectors, the position of the signal transmission section 4 was determined according to each machine tool used, but this was very complicated in manufacturing, and the signal transmission section If the position sensor 4 is installed in the wrong direction, the position sensor becomes unusable, and there is also the problem that the position sensor cannot be used for other machine tools.
