Rib frock clamp.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of press fitting gear chamfering frock clamp, it is characterised in that including：Mandrel, the mandrel are divided into linkage section, peace
Section is filled, is socketed section, the construction section coordinates with gear hole to be processed, and /V section, the /V section are provided on the linkage section
Diameter is more than the construction section diameter, and the /V section end face is bonded with the gear face to be processed, the mandrel linkage section
End face circle centre position is provided with center hole I, the center hole I and top cooperation under chamfering device；Axle sleeve, the axle sleeve are socketed in institute
It states in mandrel socket section, the axle sleeve openend is provided with flange part, and the flange part is matched somebody with somebody with the gear hole flange to be processed
It closes, forms seal face, be provided with center hole II on the axle sleeve closed end, the center hole II is matched somebody with somebody with top on chamfering device
It closes, the center hole I and II axis coaxle of center hole the mandrel can rotate during chamfered edge with the axle sleeve
The concentricity being consistent in the process avoids, there is a situation where beating, cutting through the flange part and the gear hole to be processed
Flange coordinates, and master gear can be compressed by forming seal face, and master gear is made to stablize in chamfered edge and is clamped, improves the essence of workpiece
Degree.
Preferably, the construction section is provided with 10 ° of chamferings away from described /V section one end, facilitates and installs work gear to be added
On the construction section.
Preferably, escape is provided between the construction section and the socket section, it is convenient that mandrel is processed.
Preferably, the /V section diameter is identical with the flange part diameter, is more uniformly stressed, and makes axle sleeve more firm
Clamp the work gear to be added.
The beneficial effects of the utility model are：
The utility model is by being provided with center hole II, the center hole II and chamfering device on the axle sleeve closed end
Top II cooperation, the center hole I and II axis coaxle of center hole, can during chamfered edge the mandrel and the axis
The concentricity for choosing to install and being consistent in the process is sleeved on, avoids, there is a situation where beating, promoting machining accuracy.
Coordinating by the flange part and the gear hole flange to be processed, master gear can be compressed by forming seal face,
It is that master gear stablizes clamping in chamfered edge, improves the precision of workpiece chamfered edge.
