Expanding machine is called staving press, is the equipment for processing ring-shaped work pieces.Its hydraulic pressure parts of existing expanding machine are standing on ring
The top of shape part, is pressed downward rising mould to ring-shaped work pieces reaming using hydraulic press, exists：Whole machine takes workshop and used
Area is larger, and the problem of the charging or discharging of influence workpiece.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of expanding machine, and this expanding machine can solve existing expanding machine
Volume is larger, not only wastes workshop usable floor area, and the problem of the charging and discharging of influence workpiece.
In order to solve the above problems, the technical solution adopted in the present invention is：This expanding machine, including it is fixed on deck plate
The hydraulic jack of lower surface；The upper surface of the deck plate is provided with rebound, and the piston rod of the hydraulic jack passes through described
Panel and the rebound are connected with installing the connecting rod of expanding mould；The top of the connecting rod is provided with locking member.
In above-mentioned technical proposal, more specifically technical scheme can also be：The rebound connects with the connecting rod screw thread
Connect；The locking member is locking nut；Coaxial through hole is offered on the deck plate and the rebound, the through hole is embedded
Equipped with attaching nut, the piston rod of the hydraulic jack is penetrated to be connected in the through hole by attaching nut with the connecting rod
Connect.
Further：The deck plate lower end is provided with support channel-section steel.
Further：The expanding mould includes the up big and down small cone cylinder being set in outside the connecting rod；Outside the cone cylinder
It is set with cylinder of its taper core bore corresponding to the tapered outer wall of the cone cylinder, the cylinder extracorporeal set workpiece；The cylinder
Lower end is provided with the radially-protruding boss being connected with the rebound.
Further：The hydraulic jack includes cylinder cap, cylinder bottom and the cylinder between the cylinder cap and the cylinder bottom
The cylinder flange being connected with the cylinder cap by attachment screw is set with outside cylinder, the cylinder barrel；The cylinder cap passes through fixed spiral shell
The lower surface followed closely with the deck plate is abutted against；Offered on the cylinder cap and offer spill port on fuel feed hole, the cylinder bottom, institute
State one end that piston rod is installed on piston and be provided with piston rod nut.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, because hydraulic jack is fixed on deck plate lower surface, the upper surface of deck plate is provided with rebound, the piston of hydraulic jack
Bar is connected through deck plate and rebound with installing the connecting rod of expanding mould；So, hydraulic jack and deck plate can be sunken to
Underground, only stays rebound and the connecting rod of suit enlarging die to reduce workshop area occupied in the horizontal plane, not only, facilitates
The charging or discharging of workpiece, and the production needs under special space enrironment can be met；
2nd, attaching nut is set with coaxial through hole, through hole due to being offered on deck plate and rebound, the work of hydraulic jack
Stopper rod is penetrated to be connected in through hole by attaching nut with connecting rod；So, piston rod and connecting rod axiality not only be ensure that
Reliability, and convenient disassembly；
3rd, because barrel jacket is loaded on outside cone cylinder, and the taper core bore of cylinder is corresponding with the outer wall of cone cylinder, during work, hydraulic oil
The piston rod of cylinder bounces back downwards, in the presence of the locking nut on connecting rod He its top, and cone cylinder is to move downward, make cylinder by
Gradually outside expanding, so that the core bore to workpiece carries out expanding correction, expanding dimensional accuracy is high, and the security of equipment is also high；
4th, due to being set with the cylinder flange being threadedly coupled with cylinder cap outside cylinder barrel；One end that piston rod is installed on piston, which is provided with, lives
Stopper rod nut；Not only increase the stability and reliability of hydraulic jack, it is ensured that the axiality of piston rod and connecting rod, and
Piston rod convenient disassembly.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
Expanding machine shown in Fig. 1, including hydraulic jack, hydraulic jack include cylinder cap 9, cylinder bottom 12 and located at cylinder cap 9 and cylinder bottom
Piston 16 and piston rod 8 are provided with cylinder barrel 11 between 12, cylinder barrel 11, one end of piston rod 8 is installed on piston 16, and is passed through
Piston rod nut 13 is mutually fixed with piston 16；Offered on cylinder cap 9 and offer spill port on fuel feed hole, cylinder bottom 12；Cylinder barrel 11
Outer end is set with cylinder flange 10, and cylinder flange 10 is connected with cylinder cap 9 by attachment screw；Cylinder cap 9 by fixing screws with
The lower end of deck plate 1 is abutted against；The lower end of deck plate 1 is provided with support channel-section steel 17；The upper surface of deck plate 1 is sequentially provided with from the bottom up
The rebound 3 of First Transition plate 2 and second；Coaxial lead to is offered on deck plate 1, the rebound 3 of First Transition plate 2 and second respectively
Attaching nut 4 is embedded with hole, the through hole, the other end of piston rod 8 is penetrated in the through hole by attaching nut 4 and connecting rod 5
It is connected；Expanding mould 21 is set with outside connecting rod 5, the top of connecting rod 5 is set with locking member；Locking member is from the bottom up successively
It is sleeved on first locking nut 6 and the second locking nut 7 on the top of connecting rod 5；Expanding mould 21 includes being set in outside connecting rod 5
Up big and down small cone cylinder 212；The cylinder 211 that its taper core bore corresponds to the conical outer wall of cone cylinder 212, cylinder are set with outside cone cylinder 212
