Make in the middle part of head shaft core, the shrapnel is sheathed on the pull rod and in shrapnel storage piece.
Preferably, the work head further includes location nut, and the location nut is threadedly connected to the work head axis
Shrapnel is compressed in core left end, the position by adjusting the location nut.
Preferably, the work head further includes locking nut, and the locking nut is threadedly connected to the pull rod left end.
Preferably, the shrapnel is butterfly shrapnel, and the shrapnel quantity is 6.
Preferably, the work head, which is characterized in that further include bushing, the number of bearings is 4, the bearing
It is distributed in the bushing both sides two-by-two.
Preferably, the work head, which is characterized in that further include annular copper sheet, the shrapnel and the annular copper sheet
It is sheathed on from left to right successively on the pull rod and in shrapnel storage piece.
Preferably, the work head further includes the positioning pin for fixed chuck and the pull rod, the positioning pins position
Between the collet and the pull rod right end.
Compared with prior art, bearing is added in the work head of the utility model, bearing support work head shaft core does 360 degree
Rotation, the bearing of addition increase torque, increase rigidity so that the work head is more durable；And shrapnel is added, bullet can be passed through
Piece adjusts the tightness of grips workpiece, and shrapnel increases the chucking power of work head.
