Indexing device for universal milling machine

The present invention is conventional and may be any by introducing a new structure different easier to or recline the rotational force to the main shaft of the drive motor selectively to connect, in particular the fixed and thawed to adjust the angle of the indexing head an angle can be achieved here in that on the indexing device of the universal milling machines capable of highly accurate angle adjustment, the driving body, and the drive spline shaft, the angle split housing, drive shaft and which rotates by receiving the rotational force of the drive shaft inside the connecting shaft is rotatably mounted, the rear end portion is engaged with the front end portion of the indexing housing main shaft to be rotated to rotate by receiving a rotational force the connecting shaft within and indexing head which rotates with the indexing housing, It is provided, and the front end of the indexing head coupled to the outer circumference, the tool is mounted to the main shaft Of the shaft head, wherein the drive indexing coupling portion and a front end portion and the indexing head of the drive unit to turn off is provided between the spline shaft and the indexing housing, passing or transmitting the rotational force of the driving shaft to the indexing housing after being provided between the ends, comprising one with respect to the driving body portion bound to the indexing rotation of the indexing head release restraint or constraint.
