The utility model discloses machinery inflation axle utilizes the mechanical transmission form to carry out work, and the tight scope that expands is big, can expand to phi 90mm from phi 73mm, the tight power that expands is big, and the work piece is easy slipping not, light in weight controls than the light 1.5kg of physiosis axle among the prior art, simple structure, convenient to use, it is with low costs, need not the maintenance, long service life has alleviateed operator's intensity of labour greatly.
Description
Technical field
The present invention relates to the axle in printing equipment, a kind of in printing equipment for rolling, the mechanical expansion shaft that unreels etc..
Background technology
The air-expanding shaft that printer is used at present is to be transported to the air bag inside axle by compressed air, expansion block jack-up is made to work, owing to, under this working forms, producing friction between air bag and expansion block, making the phenomenon that air bag leaks air, work is caused to stop, raw material is scrapped, the air bag that must the most more renew after air bag gas leakage, changes operational difficulties, cost is high, brings economic loss to enterprise.
Chinese patent CN201254413Y discloses mechanical expansion shaft, this main axis of dilatation is to use leading screw and skewback structure, by relatively rotating of mandrel and gripper shoe, realize expansion and the contraction of the surrounded diameter of gripper shoe, main axis of dilatation and the combination of open-close type bearing block make swollen, need to hang steel wire rope and draw this to be through at the main axis of dilatation in coil of strip part could to realize position transfer, and structure is complex, cost is high, safeguards inconvenience.
Summary of the invention
For above-mentioned problems of the prior art, the invention discloses a kind of mechanical expansion shaft, this main axis of dilatation simple in construction, tension force is big, lightweight, it is not necessary to maintenance, service life is long.
The technical scheme realizing the object of the invention is:
A kind of mechanical expansion shaft, including drive mechanism, tensioning mechanism, jacking mechanism and force-reducing mechanism, drive mechanism is connected with jacking mechanism by tensioning mechanism, tensioning mechanism, jacking mechanism are also connected with force-reducing mechanism, and drive mechanism, tensioning mechanism, jacking mechanism and force-reducing mechanism are connected as a single entity by axle sleeve.
Described drive mechanism is a power transmission shaft, and one end of power transmission shaft is provided with spacer ring and clamp nut, and clamp nut is connected with bearing.
Described tensioning mechanism is a pull bar, and pull bar one end is connected with power transmission shaft, and the other end is connected with the stage clip of force-reducing mechanism.
Described jacking mechanism includes jacking block seat and the jacking block being arranged on jacking block seat, and jacking block is that inclined-plane coordinates with jacking block seat, and jacking block is provided with torsion spring and hooked scarf, and hooked scarf is arranged on torsion spring.
Described force-reducing mechanism includes stage clip and the packing ring being connected with stage clip, and stage clip is connected with pull bar.
Mechanical expansion shaft of the present invention utilizes machine driving form to be operated, and compared with prior art, has a following good effect:
(1) swelling scope is big, can expand into Φ 90mm from Φ 73mm；
(2) tension force is big, and workpiece is difficult to skid；
(3) lightweight, about 1.5kg lighter than air-expanding shaft of the prior art；
(5) simple in construction, easy to use, low cost, it is not necessary to maintenance, service life is long, significantly reduces the labor intensity of operator.
Accompanying drawing explanation
Fig. 1 is the structural representation of mechanical expansion shaft of the present invention；
In figure: 1. spacer ring 2. power transmission shaft 3. alignment pin 4. torsion spring 5. hooked scarf 6. jacking block 7. packing ring 8. clamp nut 9. nut 10. pull bar 11. jacking block seat 12. attaching nut 13. stage clip.
Detailed description of the invention
With reference to Fig. 1, one mechanical expansion shaft of the present invention is made up of spacer ring 1, power transmission shaft 2, alignment pin 3, torsion spring 4, hooked scarf 5, jacking block 6, packing ring 7, clamp nut 8, nut 9, pull bar 10, jacking block seat 11, attaching nut 12 and stage clip 13, power transmission shaft 2 left end is connected with being easy to process the spacer ring 1 of endoporus, clamp nut 8, clamp nut 8 is connected with bearing, to compress bearing, and fixed conveyor axle 2, power transmission shaft 2 right-hand member is connected with nut 9, pull bar 10, with transmitting movement to pull bar 10 by alignment pin 3, T-shaped tooth；And strain jacking block seat 11 and axially move, jacking block seat 11 coordinates for inclined-plane with jacking block 6, and when jacking block seat 11 moves axially, jacking block 6 radially moves, and holds out against work, makes workpiece motion s；It is peripheral that torsion spring 4 is centered around jacking block 6, and jacking block 6 is also connected with hooked scarf 5, and stage clip 13 left end is connected with pull bar 10, and right-hand member is connected with packing ring 7, plays and subtracts power effect, to alleviate the labor intensity of operator.
This mechanical expansion shaft is to utilize external force to make power transmission shaft rotate, the nut and the rod assembly that are connected with T-shaped tooth with power transmission shaft is driven to axially move, this motion is delivered to be connected on the jacking block seat on nut and pull bar with common closely-pitched, jacking block seat is made also to axially move, jacking block seat drives the jacking block of end mounted thereto to do radial motion, owing to coordinating for inclined-plane between jacking block and jacking block seat, therefore jacking block raises gradually with the movement of jacking block seat, reaches to hold out against the purpose of work.
