Offset screw, the top of eccentric amount screw are provided with steel ball.
The eccentric amount screw and the diameter of steel ball coupling part are less than the A/F of bulb connecting hole, the bulb
The A/F of connecting hole is less than steel ball size, and the diameter of thread of the eccentric amount screw is more than steel ball size.
It is provided with mounting hole II on the transition disc, transition disc passes through the bolt connection lathe master that is arranged in mounting hole II
Axle.
The mounting hole I is provided with everywhere, and the T-slot is provided with two, is provided with each T-slot T-shaped at two
Block, the silk hole I are provided with two.
Transition disc is first connected on machine tool chief axis by the present invention when in use, then the dovetail of mandrel is put into the swallow of transition disc
In stern notch so that the plane of side with bulb connecting hole on dovetail and transition disc side wall is in the same side, then by eccentric amount
Screw is screwed into pressing plate, and the steel ball on its top enters bulb connecting hole, and pressing plate is fixed on transition disc；Again mandrel is passed through with screw
Mounting hole I connection transition discs in T-shaped piece, the cue mark line allowed according to the requirement to workpiece offset on mandrel and transition
Graduation mark alignment on disk, gently regulation connect mounting hole I and T-shaped piece of screw so that on the dovetail and transition disc on mandrel
Dovetail groove reliable contacts, now rotary offset heart amount screw, and pass through the connection between steel ball and bulb connecting hole and drive core
Axle carries out the fine setting of offset so that the graduation mark needed for the alignment of cue mark line；Dial gauge can also be used when adjusting offset
Measurement offset is aided in, and connection mounting hole I and T-shaped piece of screw are tightened by offset again after determining；Now by work
Part loads mandrel and locked with opening pad and locking nut, you can carries out turning to a raceway of workpiece, then unclamps lock
Tight nut and opening pad, workpiece is turned around to install fixed post-processing another raceway；When needing to adjust other offsets, only
Need to unclamp connection mounting hole I and T-shaped piece of screw, repeat said process.
