The specific embodiment
Come mechanical swelling axle of the present utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment, but can not therefore limit protection domain of the present utility model.
The structure of the mechanical swelling axle in the utility model please see Figure 1 and Fig. 2, and Fig. 1 is vertical cut-away view of mechanical swelling axle of the present utility model, and Fig. 2 is the horizontal cut-away view of mechanical swelling axle of the present utility model.As seen from the figure, mechanical swelling axle of the present utility model, keystone configuration comprises mandrel 12 and bloated axle bearing plate 13, one end of mandrel 12 is provided with square block, twisting this square block with spanner is rotated to drive mandrel 12, it is opposite that mandrel 12 middle parts are arranged with two sections hand of rotation, Dui Cheng outside thread each other, be respectively equipped with on each outside thread one with external thread rotary to identical bloated axial filament mother 4.When mandrel 12 rotated, the axial filament mother's 4 of expanding the outside was fixed, and the axial filament mother 4 of expanding does not rotate with mandrel 12, and then two bloated axial filaments female 4 inwardly or simultaneously outwards move simultaneously.
Bloated axial filament mother's 4 outer wall is provided with a plurality of tilt slide mechanisms that can slide on the axial filament mother 4 of expanding, the outside of this tilt slide mechanism is fixed with the bloated axle bearing plate 13 of arc sheet, being vertically fixed on respectively in two tilt slide mechanisms on the bloated axial filament mother 4 of each is bloated axle bearing plate 13, a plurality of bloated axle bearing plates 13 are formed a columniform outer wall around described mandrel 12.
The end at each is bloated axle bearing plate 13 two ends is fixed with side slide 7 respectively, respectively be provided with the adjustment cover 30 of symmetry on the mandrel 12 of bloated axle bearing plate 13 end positions, the effect of adjusting cover 30 is a distance of adjusting on the mandrel 12 3 of two plate washers, and the length of itself and bloated axle bearing plate 13 is adapted.The outside of adjusting cover 30 is provided with antifriction-bearing box 35 and thrust ball bearing 37, be folded with described plate washer 3 between antifriction-bearing box 35 and the thrust ball bearing 37, antifriction-bearing box 35 is stuck in the neck bearing chamber of plate washer 3, the indoor card of the outer bearing of plate washer 3 has thrust ball bearing 37, the outside of this thrust ball bearing 37 is a thrust ball bearing cover for seat 38, the outside of thrust ball bearing cover for seat 38 is fixed on the described mandrel 12 by lock sleeve 27 and fixing screw 28, the outside of plate washer 3 is fixed with at least one and pulls pin 39, the inboard of plate washer 3 is provided with side slide groove radially, side slide 7 is stuck in this side slide groove, and can radially move in the side slide groove.By the said structure setting, the axle bearing plate 13 that expands is stuck between two plate washers 3, and the rotation by mandrel 12, the axle bearing plate 13 that expands is radially slided in the side slide groove of plate washer 3, and then the expansion of the shaft diameter of realizing expanding and dwindling.
In order to prevent that bloated axle bearing plate 13 rotates together when mandrel 12 rotates, in the arranged outside of plate washer 3 pull pin 39, be placed in by a long handle spanner and pull on the pin 39, it is moving that plate washer 3 is maintained static by the long handle spanner, and then realize that the mandrel 12 axle bearing plate 39 that expands when rotating or not thereupon.The axial filament mother 4 of expanding during mandrel 12 rotations maintains static moving with bloated axle bearing plate 12, the axial filament mother 4 of expanding does straight-line motion at mandrel 12 outside thread bus places.Female 4 linear movement directions of axial filament that expand when changing mandrel 12 hand of rotation change thereupon simultaneously, and female 4 straight-line displacements of the axial filament that expands change the axle external diameter size that expands, the expansion of the shaft diameter of realizing expanding and dwindling.
Bloated axial filament mother's 4 structure is as follows: the axial filament mother's 4 of expanding outer wall is the awl column structure, and the diameter of an end is big, and the diameter of the other end is little; Axial filament mother 4 the inwall of expanding be provided with mandrel 12 on the cooresponding negative thread of outside thread (left and right revolving).Two bloated axial filament mothers 4 are symmetrical arranged on mandrel 12, promptly or the bigger ends of two diameters simultaneously outwards, perhaps two bigger ends of diameter simultaneously inwardly, to guarantee when mandrel 12 rotates, two symmetrically arranged bloated axial filaments female 4 perhaps shrink to the center of mandrel 12 simultaneously simultaneously to the expansion of the two ends of mandrel 12.
In the mandrel 12 each other symmetry about revolve the outside thread direction setting be subjected to force direction relevant with the axle outside diameter wall that expands, (be uncoiling direction or take-up direction, active uncoiling in other words still is passive uncoiling.) external force direction is subjected to force direction opposite with mandrel, applies the axial filament mother 4 of expanding after the external force and moves to mandrel 12 center positions, keeps the swelling state.
Utilize the method for above-mentioned mechanical swelling axle handling coil of strip spare, comprise the steps:
1. the mandrel 12 of rotary machine main axis of dilatation makes the column reduced diameter that is surrounded by a plurality of bloated axle bearing plates 13, the mechanical swelling axle is penetrated in the endoporus of coiled material piece;
2. the long handle spanner that utilizes an end to have two trepannings is placed in described pulling on the pin 39, a square hole wrench that has square opening is placed on the described square block again;
3. keep the long handle spanner motionless, rotate the square hole spanner, mandrel 12 is rotated and the axle bearing plate 13 that expands is motionless, its outer diameter is increased, until the endoporus that holds out against coiled material piece;
4. with a hoisting device that has two lifting ropes, lifting rope places the two ends of mandrel 12 respectively, hangs and draws coiled material piece to the work area.
