Frock for the processing of cylindrical axial keyway
A kind of frock for the processing of cylindrical axial keyway is the utility model is related to, belongs to field of machining, is suitable for
The processing of the axial all kinds of overlength keyways of circle product external.
In field of machining, there are many axial workpieces to need Milling Process keyway.To ensure machining accuracy, in keyway
, it is necessary to which clamping workpiece is fixed during Milling Process.Existing frequently-used shaft forgings keyseat clamping tooling is only with Set and Positioning
The mode at axial workpiece both ends, although disclosure satisfy that the requirement of part keyway processing, when axial workpiece length is longer, weight
To measure heavier, it is desirable to during processing annular keyway, it may appear that device travel is inadequate, or needs multiple clamping, while in detection milling
Oscillation phenomenon occurs in process, keyway machining accuracy is very poor, and dynamic balancing is unsatisfactory for requiring.
It is longer for length, heavier-weight, it is desirable to the annular keyway product of processing, such as：Grid roller is, it is necessary to processing excircles ring
Shape overlength keyway, product grow 1.8 meters, weigh 1.5 tons.It requires processing keyway quantity 12, and requirement on machining accuracy is high, and finished product needs
Carry out dynamic balancing measurement.When numerical control borer is processed, the Z strokes of equipment are inadequate.When numerical control gantry is processed, with omnipotent head into
Row processing, but multiple clamping is needed, precision is inadequate, and dynamic balancing measurement is unqualified.
