Abstract
The utility model relates to an expansion sleeve which comprises at least two expansion sleeve plates and an elastic deformation part between the expansion sleeve plates. The expansion sleeve provided by the utility model overcomes the technical problems that in the prior art, production efficiency is low, use is inconvenient, a thick expansion sleeve is not easy to expand and the like. The utility model provides the expansion sleeve which is high in utilization ratio, convenient to use and cost-saving.
Description
Technical field:
The utility model relates to a kind of ringfeder.
Background technology:
When the design ringfeder, be convenient to expand at present, can only locate the anti-conical surface size that pushes away ringfeder of diameter dimension according to ringfeder, a counter then axle conical surface size of inferring in order to make ringfeder.Cause the corresponding a kind of apotting spindle in aperture, almost a kind of location, both increased design and manufacturing cost, change product to production line again and make troubles.Change product at every turn and all must change axle, the school anchor clamps greatly reduce production efficiency again.Normally ringfeder is axially milled into groove, realize to expand, though can expand, its shortcoming that has is, spline is embedded in the groove easily during the splined hole location, and locating effect is poor slightly.The product strain is little, is generally between 0.1～0.15mm.So, if produce similar product, be held portion size and a little a bit change, just must must design a new ringfeder, adverse effect such as this not only causes the stock big, also causes the time waste of product transformation production, and the cycle is elongated.
Summary of the invention:
The utility model overcome in the prior art production efficiency low, use inconvenient and thick ringfeder is difficult for technical problems such as expansions, the ringfeder of high, the easy to use and saving cost of a kind of utilization rate is provided.
In order to solve the problems of the technologies described above, to reach above-mentioned beneficial effect, thereby provide a kind of ringfeder, this ringfeder to comprise at least two ringfeder sheets and be arranged on the elastic deformation part between the said ringfeder sheet.
Preferably, above-mentioned elastic deformation part is metallic elastic deformation component or nonmetal elastic deformation part.
Preferably, when above-mentioned elastic deformation part was the metallic elastic deformation component, said metallic elastic deformation component was spring, spring leaf or foil.
Preferably, above-mentioned ringfeder sheet is fixedly connected through the metallic elastic deformation component.
Preferably, when above-mentioned elastic deformation part was non-metallic elastic deformation component, said nonmetal elastic deformation part was a rubber.
Preferably, above-mentioned ringfeder sheet bonds together through nonmetal elastic deformation part.
Adopt technique scheme, have following useful technique effect at least:
Adopted multiple structure, the part metals that the thick ringfeder of influence is expanded cuts away, and has realized that thick ringfeder is as the easy expansion of thin ringfeder.The utility model can guarantee that ringfeder expands smoothly owing to can ringfeder be done the thick while; Can in being applied to produce, only need to change ringfeder and can change product with apotting spindle unification to 2 to 3 kinds; Promptly save the design and the manufacturing cost of apotting spindle, reached the purpose that fast quick change produces again.
Description of drawings:
Fig. 1 is the structural representation of the ringfeder that provides of the utility model;
Fig. 2 is the vertical view of the ringfeder that provides of the utility model;
The numbering explanation:
1-ringfeder sheet; The 2-elastic deformation part.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, a kind of ringfeder comprises at least two ringfeder sheets 1 and is arranged on the elastic deformation part 2 between the ringfeder sheet 1, and ringfeder sheet 1 links together through the elastic deformation part, forms various structure.In use, because deformation directly takes place in elastic deformation part's effect, reach the purpose of shrinking or expanding.
The utility model in use, ringfeder is set on the axle, the inner conical surface of ringfeder and the male cone (strobilus masculinus) of axle cooperate; When pull bar pulling ringfeder end face; Because ringfeder and axle are cone match, the axially-movable of pull bar ringfeder is transformed into the radial motion of ringfeder, causes that ringfeder expands; General inflatable 0.1～1.5mm, the endoporus of final clamping work pieces.
