The size range of endoporus is big, and positioning, the structure of release workpiece is are rigidly connected, reliable in action.
Mandrel is cased with the conical core shaft, mandrel is located at the right side of base.Mandrel plays caused iron in shielding turning
The effect of bits, to prevent influence of the iron filings to frock.
The guiding mandrel is provided with spring two, and spring two is located at the left side of conical core shaft.In the operation of workpiece is removed,
Spring two is played conical core shaft top role, and such workpiece is more convenient to be taken off.
The cross section of the handle left end is square groove, and the square cross-sectional shape of the square groove and clamp nut matches
Close.Handle convenient card is on clamp nut, additionally it is possible to bears bigger power.
It is bolted between the base and the bottom plate and between bottom plate and platen.
The locking nut and the base periphery of the base junction are arranged to plane.So clamping screw is installed
Can more it stablize in base.
Compared with prior art, beneficial effect possessed by the utility model is：
1st, the utility model can ensure that the disc of workpiece diverse location and endoporus have higher axiality, and adaptation is determined
The size range of position endoporus is big, and positioning, the structure of release workpiece is are rigidly connected, reliable in action.
2nd, mandrel is cased with conical core shaft, mandrel is located at the right side of base.Mandrel plays caused iron filings in shielding turning
Effect, to prevent influence of the iron filings to frock.
3rd, it is oriented to mandrel and is provided with spring two, spring two is located at the left side of conical core shaft.In the operation of workpiece is removed, bullet
Spring two is played conical core shaft top role, and such workpiece is more convenient to be taken off.
4th, the cross section of handle left end is square groove, and the square cross-sectional shape of the square groove and clamp nut matches
Close.Handle convenient card is on clamp nut, additionally it is possible to bears bigger power.
5th, locking nut and the base periphery of base junction are arranged to plane.So clamping screw is arranged on base
It is interior more to stablize.
