Description
Technical field
The utility model belongs to the sleeve swelling device field that profile can harmomegathus, is specifically related to a kind of liquid, gas accessory machinery harmomegathus axle.
Technical background
All widely apply the harmomegathus sleeve in weight industry at present, in the non-metals processing industry, in the production and intermediate transportation circular flow of aluminium sheet, aluminium foil, mainly adopt two kinds of versions of steel bushing and paper sleeve.Steel bushing relatively is fit to the internal work transport turnover.When each manufacturer carries out the transportation reprocessing transnational, district transprovincially of aluminium material volume, if employing steel bushing, after then the other side unit uses up, steel bushing originally also has former road to return to original production unit, will increase the sleeve traffic cost greatly like this, take the sleeve operating cycles, be not easy to both sides' production control, also damage sleeve simultaneously easily, cause precise decreasing.With respect to the above defective of steel bushing, can adopt paper sleeve to carry out, but paper sleeve need corresponding harmomegathus sleeve to produce conversion in intermediate link transportation turnover.
On the market multiple harmomegathus sleeve is arranged now, the pneumatic harmomegathus quill shaft of common air sac, anti-load capacity is poor, and institute rises when expecting that volume weight is big, and the air bag distortion is serious, and operating accuracy can't guarantee.General mechanical harmomegathus sleeve, complex structure, difficulty of processing is big.Some mechanical sleeve tensioners are locked with spanner with manpower, and it is time-consuming to require great effort.Generally only adopt 1 center link, length is longer.Tightening piece and tension shaft only at both ends support, and when material volume weight was big, middle leading screw was bent, and accuracy of positioning is not good.Adopt the sleeve of cam gear, intermediate conversion links is many, and accuracy of positioning is inaccurate.That adopts common hydraulic pressure harmomegathus sleeve needs to adopt special joint in the course of the work, constantly ftercompction in the work rotary course.Can't disconnect with pumping plant, and equipment price is high.A lot of harmomegathus sleeves do not have automatic compensation function, in process of production, roll up the increase of internal diameter along with the material of required tensioner, when the tightening piece external diameter of harmomegathus sleeve can not increase accordingly, originally the material of institute's tensioner volume can be loosening, do not skid when finishing as yet in production, causes production to proceed.Thereby produce a large amount of waste materials.
The utility model content
The purpose of this utility model is to solve prior art mechanical type harmomegathus apparatus structure complexity, uses inconvenience, and anti-load-bearing capacity is poor, the defective of low precision, provide a kind of simple in structure, use liquid, gas accessory machinery harmomegathus axle reliable, applied widely.
The utility model is achieved through the following technical solutions:
Be a kind of liquid, gas accessory machinery harmomegathus axle, the sleeve shell that comprises hollow, it is characterized in that the sleeve shell both sides are provided with the notch of symmetry, notch is a plurality of and five equilibrium sleeve shell circumference, tightening piece is installed in the notch, the sleeve shell bosom is provided with thrust unit, the thrust unit both sides are respectively equipped with the axis of symmetry, on two axis midship mounting is installed all, midship mounting is connected with tightening piece by strut bar, midship mounting is provided with the bearing groove with strut bar end coupling, tightening piece is provided with the medial launder with strut bar other end coupling, described strut bar is hinged by bearing pin and midship mounting and tightening piece respectively, midship mounting, strut bar, tightening piece is formed four-bar linkage.Tightening piece described in the utility model is a plurality of, and five equilibrium sleeve shell cross section, and cooresponding strut bar is many groups, and it is the reinforcement structure that midship mounting, strut bar, tightening piece are formed four-bar linkage, can utilize little axial thrust to produce big radially expanding force.
Described thrust unit is a hydraulic actuating cylinder, the piston rod of hydraulic actuating cylinder and hydraulic actuating cylinder bottom are equipped with the perforate spindle nose, the inner of two axis is equipped with center hole, the hole wall of center hole is provided with the transmission pin-and-hole, and the piston rod of hydraulic actuating cylinder is connected by pin by the center hole of two axis of perforate spindle nose insertion respectively with the hydraulic actuating cylinder bottom.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in drawings: sleeve shell 1 inner both sides are installed criss cross lateral branch fagging 2 and medial branch fagging 7 respectively, fix with screw 23 between lateral branch fagging 2, medial branch fagging 7 and the sleeve shell 1, sleeve shell 1 middle part is provided with loading and unloading access opening 1.2, can carry out the installation and maintenance operation of thrust unit, sleeve shell 1 both sides are respectively equipped with 4 notches 1.1, are provided with the tightening piece 3 of coupling in the notch 1.1.
The thrust unit that sleeve shell 1 bosom position is provided with adopts hydraulic actuating cylinder, hydraulic actuating cylinder comprises hydraulic cylinder 11, hydraulic actuating cylinder end cap 9, hydraulic actuating cylinder bottom 12, hydraulic piston 24 and piston rod 13, the hydraulic actuating cylinder that present embodiment adopts is nonstandard oil cylinder, hydraulic actuating cylinder screw 10 is loaded on hydraulic cylinder 11 inboards, reduced the oad of hydraulic cylinder 11, piston rod 13 ends and the hydraulic actuating cylinder bottom 12 of hydraulic actuating cylinder are equipped with perforate spindle nose 12.1.
Two axis 15 support and centralized positioning by the lateral branch fagging 2 and the medial branch fagging 7 of sleeve shell 1 both sides, and the inner of two axis 15 is equipped with center hole 15.1; The hole wall of center hole 15.1 is provided with transmission pin-and-hole 15.2, and the piston rod 13 of hydraulic actuating cylinder is connected by pin 14 by the center hole 15.1 that perforate spindle nose 12.1 inserts two axis 15 respectively with hydraulic actuating cylinder bottom 12.
Axis between external support board 2 and the interior stay bearing plate 7 is provided with midship mounting 6, and midship mounting 6 utilizes bearing centre hole 6.4 to be enclosed within on the axis 15, and axial restraint is carried out by axis convex shoulder 15.3 and two jam nuts 16 respectively in two ends.Midship mounting 6 is provided with 4 bearing grooves 6.3 of symmetrical distribution, tightening piece 3 is provided with medial launder 3.6, strut bar 5 two ends are installed in respectively in bearing groove 6.3 and the medial launder 3.6, connect by bearing pin 4, and the midship mounting 6 of the same side, strut bar 5, tightening piece 3 are formed four-bar linkage.
When the utility model uses: as shown in Figure 8, the primer fluid cylinder pressure, two axis 5 of cylinder pushes are when stretch out both sides, the axis convex shoulder 15.3 of axis 5 promotes midship mounting 6, the parallelogram four-bar linkage that drive strut bar 5 and harmomegathus piece 3 are formed rises outside notch 1.1 carries out, the piece facade 3.3 that rises of tightening piece is contained in the notch 1.1, the circumference tangential motion of restriction tightening piece 3, the axial motion of the piece end cambered surface 3.5 restriction tightening pieces 3 that rise of tightening piece, tightening piece 3 can only carry out radially harmomegathus along notch 1.1 and move, till being withstood by the inwall of sleeve shell 1.Notch 1.1 is uniform along the circumference symmetry, guarantees symmetrically and evenly flexible of each tightening piece 3.Till being withstood by the inwall of sleeve shell 1.Four connecting rod step-up systems, along with the release of the piston rod 3 of hydraulic actuating cylinder, strut bar 5 progressively increases with the angle of axis 15, and the thrust of generation also constantly increases, and this structure utilizes less axial force can produce very big radial thrust, makes tensioner reliable.
