It is joined with bolts by bail；Ant boring axle journal clamping support is provided with described middle stern tube shaft V-type bail, it is described
Ant boring axle journal clamping support is fixed on middle stern tube shaft V-type bail by clamping stud；Described ant boring axle journal clamps
Ant boring is provided with frame, the boring bar coaxial with middle stern tube shaft flange connecting hole is provided with described ant Boring machine.
As preferable technical scheme：Described middle stern tube shaft V-type bail includes upper hoop and lower hoop, described clamping double end
Bolt is connected with upper hoop；Described ant boring axle journal clamping support includes restocking and undercarriage, is connected by clamping stud
Fastening.
As preferable technical scheme：Described clamps stud length and the center distance of middle stern tube shaft flange connecting hole
Degree, which coordinates, to be adapted to.
As preferable technical scheme：Described clamping stud is provided with packing ring with bail with bolt.
As preferable technical scheme：Copper sheet pad is provided between described middle stern tube shaft V-type bail and middle stern tube shaft axle journal
Piece.
The utility model adjusting range is wide, and applicable performance is big, has given full play in different diameters, different centre-to-centre spacing ships
Flexibly used when oceangoing ship jackshaft stern tube shaft and similar shaft flange connecting hole boring hinge processing and clamping, so as to solve over a size
Jackshaft stern tube shaft flange connecting hole it is necessary to make the clamping tooling of a set of adaptable size, be effectively improved the profit of frock
With rate, solve the special wasting phenomenon used of limitation, greatly save fee of material and the processing charges of frock, reduce and be produced into
This.Meanwhile the mitigation of frock, the reduction of quantity, it is the stacking place that operating personnel reduced labor intensity and reduced frock.
