The spring is placed on outward flange；The spring washer is mounted on the boss of inner flange, is contacted with spring；The connecting rod
Screw rod pass through inner flange through-hole and outward flange through-hole, be fixed on outward flange；The linear bearing is mounted on inner flange
Through-hole in, contacted with connecting rod and inner flange；The fixing screws screw in the screw hole of connecting rod.
Further, the central axis is Morse's taper axis, is easily mounted on tailstock tool.
Further, centre drill is installed on the elastic collet, is fixed with pressure cap.
Further, the central axis is equipped with round nut, and round nut is pressed on the outer ring of the first roller bearing.
Further, snap ring is equipped in the inner flange, snap ring is stuck among the second roller bearing and thrust ball bearing, and
It is contacted with two bearing faces, keeps the fixation of inner flange.
Further, the through-hole diameter of the outward flange is less than inner flange through-hole diameter, is used for fixed connecting rod.
Application method:
1) centre drill is mounted on the elastic collet of the present apparatus.
2) present apparatus is mounted on tail stock by Morse's taper central axis.
3) it adjusts fixing screws cooperation dial gauge and clamping, correction is carried out to workpiece in lathe tail end.
4) after the completion of adjusting, start lathe, at this moment workpiece quickly rotates under the clamping support of the present apparatus.Then tail is shaken out
Cover for seat cylinder moves forward, and present apparatus central axis and then moves forward, and the centre drill Forward being mounted on elastic collet is driven, in work
Centre bore is got on part.
Of the invention has the advantages that
1) present apparatus is other than having the function of to be suitable for the clamping of common workpiece, moreover it is possible to carry out clamping to eccentric part and bore
Centre bore.
2) installation center frame is not needed when centering, non-cutting time needed for reducing workpiece positioning and correction, is improved
Production efficiency.
3) present apparatus is easy for installation, and overall weight is light and handy, is easily installed, convenient, laborsaving, safe, not only improves labour
Condition, and reduce the technical level requirement of worker.
