The expansion core of tubulose is equipped in elastic expansion sleeve, which passes through the elastic expansion sleeve, and the front periphery of the expansion core from back to front
Pre-small post-large male cone (strobilus masculinus) is formed, expansion core is cooperated by the inner conical surface being arranged on the male cone (strobilus masculinus) and the expansion set head；It is described swollen
In-core is provided with the pull rod for passing through the expansion core from front to back, and the front end of the pull rod is connected with platen, and platen is crimped on described
On the front end face on expansion set head.
Using above technical scheme, base sheath, intermediate cover for seat and end face positioning sleeve form entirety and are used as outer casing section
Point, other component is set, and all parts are arranged in the through cavity that is specifically formed.Elastic expansion sleeve with the expansion core conical surface by matching
It closes to realize expansion, and then workpiece is tightened, pull back expansion set head particular by the platen on pull rod, make its distending,
Workpiece is tightened.Disk periphery carries out major diameter centering by external splines to cover to workpiece tooth.
Further, for the ease of on grinding machine stayed mast securely and be steadily applied on the stayed mast of the utility model,
The rear end of the base sheath is provided with pull rod connector sleeve, and the rear end of the pull rod is fixedly attached on the pull rod connector sleeve.
Further, it is assembled on pull rod connector sleeve for the ease of pull rod, the pull rod is threadedly coupled with the pull rod connector sleeve.
Further, in order to make elastic expansion sleeve form axially uniform distending, eliminate or reduce the taper after distending, it is ensured that right
Workpiece is reliably tightened, and the front of the pull rod connector sleeve is fixedly installed with multiple push-pull rods, and the push-pull rod passes through the bottom
Cover for seat, and front end is fixedly attached on the ring flange of expansion set pipe portion inner end formation.
Further, in order to which expansion set head is oriented to and is limited, interior flower is provided on the inner wall of the end face positioning sleeve
Key.
The utility model has the advantages that the utility model is novel, design is reasonable and easy to use, it is swollen from inside to outside by being covered to tooth
It opens and tightens workpiece, carry out major diameter centering using the external splines of elastic expansion sleeve, ensure that the accuracy for gripping position, while benefit
Workpiece is tightened with the form of distending, it is reliable and stable, it is ensured that the accuracy of subsequent chamfer machining.
