With simple structure, the torsion ring assembling and fixing device can limit theswinging amplitude of the elastic pieces within certain range.
Description
Technical field
The utility model refers to especially that about a kind of torsion ring a kind of outer wall has the torsion ring mount device of projection.
Background technology
The rewinding process generally comprises operations such as charging, coiled strip, discharging and sticking limit, and wherein the coiled strip operation is mainly finished by rewinding mechanism and pressure mechanism, and rewinding mechanism comprises a pair of rewind roll, in order to rotate the volume core.In the winding process,, therefore can cause the tension force of Ge Do coiled material not exclusively equal, and then cause coiled material became uneven on each volume core because the variable thickness of the material that will reel is identical all the time surely.
The prior art employing is provided with unidirectional torsion ring and solves this problem between volume core and rewind roll.This unidirectional torsion ring is the Baltimore groove structure, and open the Baltimore groove upper end, is provided with flap torsion body in the groove, and this flap torsion body is connected with the Baltimore groove inwall.The Baltimore groove outer wall slips with the volume core.When thicker part contacted with pressure mechanism on the volume core, the pressure that is subjected to was bigger, produces slide relative between rewind roll and the unidirectional torsion ring, made coiled material obtain suitable elasticity.
But the unidirectional torsion ring of this kind has bigger width, therefore can not be applied to the less volume core of width.
Summary of the invention
The utility model provides a kind of width can accomplish very little torsion ring mount device, and this torsion ring mount device action effect is stable, long service life.
The utility model adopts following technical scheme:
A kind of torsion ring mount device, comprise cylindrical shell and bearing, this bearing is arranged at cylindrical shell one end, this cylinder body outer wall has several strip grooves that form vertically, be provided with projection in those strip grooves, this projection is connected by elastic component with the strip groove bottom, and described cylinder body outer wall is also radially subside and is formed with an annular groove, this cannelure runs through described strip groove and projection, is provided with stop part in this annular groove.
Described stop part is an elastic element.
Described elastic element can be spring; This spring is made of the multilayer spring coil that the coiling of metal lengthy motion picture forms, and can be 3 layers.
Between the top and end of described metal lengthy motion picture, be positioned at spring coil on the interlayer on the less circular arc and have stepped appearance bending.
Described strip groove runs through cylinder body outer wall vertically.
The utility model is provided with elastic component at cylinder body outer wall, can dwindle the volume of torsion ring, makes to make the torsion ring mount device with less width.
The utility model utilizes the hunting range of stop limits projection, the oscillating quantity of projection can be limited within the specific limits, prevents that projection breaks away from bar-shaped trough.
The utility model utilizes spring as stop part, and makes the cross section of spring rectangular, can guarantee that stop part is equal substantially to the screen resilience that each projection produces.

The specific embodiment
With reference to figure 1, the utility model comprises cylindrical shell 10 and bearing 20, and this bearing 20 is arranged at cylindrical shell 10 1 ends, and cylindrical shell 10 is cylindric, has outer wall 11 and inwall 12.This cylinder body outer wall 12 has several strip grooves 14 that form vertically, is provided with projection 16 in those strip grooves 14, and this projection 16 is connected by elastic component 17 with strip groove 14 bottoms.Described strip groove 14 axially runs through cylinder body outer wall 11 along cylindrical shell 10, and open at strip groove 14 two ends.Projection 16 can radially stretch, also can be along strip groove 14 swings.Cylindrical shell 10 is also radially subside from outer wall 11 and is formed an annular groove 13, and this cannelure 13 runs through described strip groove 14 and projection 16, is provided with stop part 15 in this annular groove 13.
As shown in Figure 2, stop part 15 runs through and backstop projection 16 by the projection groove of offering on the projection 16 18, the degree of depth that annular groove 13 is radially subside is less than the degree of depth of strip groove 14, the internal diameter 152 of stop part 15 is around the bottom 132 of cannelure 13, therefore ccontaining stop part 15 can cooperate with the projection groove 18 offered in the projection 16 in the cannelure 13, the oscillating quantity of projection 16 is limited within the specific limits, prevent that projection 16 breaks away from strip grooves 14.
Fig. 3 shows the structural representation of stop part 15, and as shown in the figure, stop part 15 is an elastic element, can be spring, also can be other elastic component.Spring is to be made of around the multilayer spring coil that cylindrical shell ring system forms the metal lengthy motion picture, can be 3 layers or multilayer.On the spring coil of interlayer, between the top and end of described metal lengthy motion picture, be positioned at spring coil on the less circular arc and have stepped appearance bending; In other words, if the metal lengthy motion picture is from upwards bending of bottom, the top of metal lengthy motion picture is positioned on the spring coil of lowermost layer, the end of metal lengthy motion picture is positioned at top spring coil, the part of the spring coil of interlayer between this top and end then, can upwards be bent to metal lengthy motion picture top from metal lengthy motion picture end, so that be positioned at substantially on the same horizontal surface with the metal lengthy motion picture of one deck spring coil.The spring cross section is rectangular like this, the backstop power of equal gentleness substantially that spring forms each projection 16.
With reference to figure 4, this figure shows that the utility model also can otherwise be used with other workpiece certainly with a kind of situation of the utility model and the use of other workpiece fits.As shown in the figure, during application, at the cylindrical shell 10 outer walls 11 sheathed overcoat workpiece 200 of torsion ring mount device 100, this moment projection 16 apical grafting overcoat workpiece 200 inwalls.
The utility model is simple in structure, and it is very little that width can be done, and the oscillating quantity of projection can be limited within the specific limits protection torsion ring mount device.
The above only is preferred embodiment of the present utility model, and those skilled in the art under the situation that does not break away from technology category of the present utility model, still can do multiple variation to it, and these variations all should be considered as scope disclosed in the utility model.
