The utility model relates to a mechanical connecting rod type inner hole expansion device in the technical field of strip steel uncoiling machines. The mechanical connecting rod comprises a hollow main shaft, one end of the main shaft supports a machine body in a rotating mode, the interior of the outer end, stretching out of the machine body, of the main shaft is provided with a sliding column in a sliding fit mode, a lead screw is rotatably connected into the sliding column, and the sliding column is connected with the lead screw through a thread pair. The periphery concentric with the main shaft is provided with a plurality of bearing sleeves parallel to the main shaft in the circumferential direction, one end of each bearing sleeve is in sliding connection with a side board vertically fixed on the main shaft, and the inner sides, corresponding to the main shaft, of the bearing sleeves are rotatably connected with connecting rods through hinge pins. The main shaft is provided with windows through which the connecting rods can penetrate conveniently, and the other end of each connecting rod is in rotating connection with the sliding column through hinge pins. The occurrence that steel coils bounce due to eccentricity can be avoided when the steel coils with inner holes with different diameters are expanded, and the strength and the bearing capacity of the expansion device and the main shaft can be guaranteed.

Description

Mechanical linkage formula inner hole expanding device
Technical field
The utility model relates to band steel decoiling unit technical field, and particularly a kind of mechanical linkage formula inner hole expanding device, for the endoporus swelling with the steel decoiling unit.
Background technology
At present, the endoporus swelling mode that the steel band decoiling unit adopts has link-type, Wedge type etc.Its principle is all the purpose that the sleeve by regulating the main shaft outside reaches swelling.But said structure is not suitable for the band coil of strip that endoporus is less than 300 millimeters, because endoporus is too little, main shaft restricted diameter system in structure design, cause intensity can not reach operating needs, usually will be with coil of strip to be placed directly on main shaft, in uncoiling process, band coil of strip endoporus on main shaft because bias produces the upper and lower play of steel coil strip, not only affect the uncoiling quality, main shaft is also easily impaired simultaneously.
The utility model content
The problem that the utility model exists for prior art, provide a kind of mechanical linkage formula inner hole expanding device, avoids coil of strip bias and play while being intended to make the band coil of strip swelling of various diameter of bores, and guarantee intensity and the load-carrying capacity of swelling device and main shaft.
The purpose of this utility model is to realize like this, a kind of mechanical linkage formula inner hole expanding device, comprise hollow spindle, described main shaft one end and fuselage rotational support, the slides within cooperation that main shaft stretches out the fuselage outer end is provided with traveller, the traveller inner rotation is connected with screw mandrel, and described traveller is connected by screw thread pair with screw mandrel; The periphery concentric with described main shaft is circumferentially with some supporting sleeves parallel with main shaft, described supporting sleeve one end be vertically fixed on the side plate sliding block joint on main shaft, the inboard that described supporting sleeve is corresponding with main shaft is rotatably connected to connecting rod by bearing pin, on described main shaft, corresponding being provided with is convenient to the window that connecting rod penetrates, and the described connecting rod other end is rotationally connected by bearing pin and traveller.
In inner hole expanding device of the present utility model, coordinate suit with the coil of strip endoporus with the supporting sleeve circumferentially arranged along main shaft periphery, during swelling, rotary screw rod drives traveller by screw thread pair and endwisely slips in main shaft, traveller drives supporting sleeve by connecting rod and radially slides along main shaft, make supporting sleeve and the swelling of band coil of strip endoporus, thus bias or play while effectively preventing that steel band from rotating; And in the utility model, traveller is placed in to main shaft inside, makes the expansion mechanism compact conformation, be applicable to the swelling with coil of strip that interior hole dimension is little, simultaneously, be built in the traveller of main shaft inside, can strengthen the intensity of main shaft, improve the load-carrying capacity of main shaft.
During for ease of swelling, supporting sleeve radially slides freely along main shaft periphery, and the position that described supporting sleeve is connected with side plate is provided with roller, the corresponding guide groove coordinated with roller that is provided with on the extend radially line corresponding with main shaft on described side plate.
For ease of the rotation of screw mandrel, described screw mandrel is rotationally connected by bearing and spindle nose and stretches out the main shaft outer end and is provided with the clamping end of being convenient to the instrument rotation.
The accompanying drawing explanation
Fig. 1 is mechanical linkage formula inner hole expanding device constructional drawing of the present utility model
Wherein, 1 main shaft; 2 bearings; 3 screw mandrels; 3a clamping end; 4 travellers; 5 connecting rods; 6 bearing pins; 7 supporting sleeves; 8 rollers; 9 side plates; 10 fuselages.
The specific embodiment
Be illustrated in figure 1 mechanical linkage formula inner hole expanding device of the present utility model, comprise hollow spindle 1, main shaft 1 one ends and fuselage 10 rotational support, the slides within cooperation that main shaft 1 stretches out fuselage 10 outer ends is provided with traveller 4, traveller 4 inner rotation are connected with screw mandrel 3, and traveller 4 is connected by screw thread pair with screw mandrel 3; The periphery concentric with main shaft 4 is circumferentially with some supporting sleeves parallel with main shaft 47, supporting sleeve 7 one ends be vertically fixed on side plate 9 sliding block joints on main shaft 1, the inboard that supporting sleeve 7 is corresponding with main shaft 1 is rotatably connected to connecting rod 5 by bearing pin 6, on main shaft 1, corresponding being provided with is convenient to the window that connecting rod 5 penetrates, and connecting rod 5 other ends are rotationally connected by bearing pin 6 and traveller 4; The position that supporting sleeve 7 is connected with side plate 9 is provided with roller 8, the corresponding guide groove coordinated with roller 8 that is provided with on the extend radially line corresponding with main shaft 1 on side plate 9; Screw mandrel 3 is rotationally connected by bearing 2 and main shaft 1 end and stretches out main shaft 1 outer end and is provided with the clamping end 3a of being convenient to the instrument rotation.
In inner hole expanding device of the present utility model, coordinate suit with the coil of strip endoporus with the supporting sleeve 7 circumferentially arranged along main shaft 1 periphery, rotary screw rod 3 drives traveller 4 by screw thread pair and endwisely slips in main shaft 1, traveller 4 drives supporting sleeve 7 by connecting rod 5 and radially slides along main shaft 1, make supporting sleeve 7 and the swelling of band coil of strip endoporus, thus bias or play while effectively preventing that steel band from rotating; And in the utility model, traveller 4 is placed in to main shaft 1 inside, makes the expansion mechanism compact conformation, be applicable to the swelling with coil of strip that interior hole dimension is little, simultaneously, be built in the traveller 4 of main shaft 1 inside, can strengthen the intensity of main shaft 1, improve the load-carrying capacity of main shaft 1.
