Abstract
The utility model discloses the interior Bloated tight cartridge for large aperture Workpiece clamping, it is made of the clamping section, location division and flange portion of integrative-structure, clamping section along the circumferential direction opens up a plurality of slit shearing groove, clamping part is cut into the clamping section unit of more valve independences by a plurality of slit shearing groove, it is characterised in that：The clamping section has Cylinder inner bore, and Cylinder inner bore is equipped with interior support set, the cylindrical matching Cylinder inner bore of interior support set, and the endoporus of interior support set has conical design, and interior support set is along the circumferential direction divided into the interior support set unit of more valve independences and is located remotely from each other.The utility model is exclusively used in the elastic clamping of large aperture workpiece, simple in structure.
Description
Technical field
It the utility model is related to a kind of elastic collet, and in particular to a kind of elastic collet of interior expansion chuck.
Background technology
Interior Bloated tight cartridge is used for the clamping of inner hole of workpiece, is that a kind of realize automates cylindrical, end face processing commonly use
Instrument.Interior Bloated tight cartridge is made of the clamping section, location division and flange portion of integrative-structure, and clamping section is used for the folder of inner hole of workpiece
Tightly, location division is used for the positioning of workpiece end face, and flange portion is used for the installation of collet, and operation principle is by the circular cone to clamping section
The compression of endoporus, makes the clamping section for opening up slit shearing groove produce outside elastic deformation, the clamping of clamping section is cylindrical to be pointed to
Cylindrical inner hole of workpiece is clamped to be clamped.But for some large aperture workpiece, the clamping excircle dimension of clamping section also can be compared with
Greatly, to ensure that clamping section has sufficiently resilient deformability, the wall thickness of clamping section cannot be blocked up, so needing the circular cone of clamping section
Being also sized to for endoporus is larger, so also just need compress clamping section circular cone endoporus push-and-pull head be also sized to it is larger, push and pull
The bar footpath of bar also accordingly becomes larger, so the related components variation that can use supporting interior Bloated tight cartridge, stock buildup cost
And influence to manage.
The content of the invention
In view of the deficiency of background technology, the purpose of this utility model aims to provide a kind of elasticity for being exclusively used in large aperture workpiece
Clamp, interior Bloated tight cartridge simple in structure.
The utility model is adopted the following technical scheme that to complete：
For the interior Bloated tight cartridge of large aperture Workpiece clamping, it is made of the clamping section, location division and flange portion of integrative-structure,
Clamping section along the circumferential direction opens up a plurality of slit shearing groove, and clamping part is cut into the clamping of more valve independences by a plurality of slit shearing groove
Portion's unit, it is characterised in that：The clamping section has Cylinder inner bore, and Cylinder inner bore is equipped with interior support set, the cylindrical matching of interior support set
The Cylinder inner bore, the endoporus of interior support set have conical design, and interior support set is along the circumferential direction divided into the inner support of more valve independences
Set unit is simultaneously located remotely from each other.
The clamping section along the circumferential direction opens up six slit shearing grooves, and clamping part is cut into six by six slit shearing grooves
The clamping section unit of valve independence, the interior support set are along the circumferential direction divided into the interior support set unit of six valve independences, and clamping section is single
It is first to be corresponded with interior support set unit.
Using the interior Bloated tight cartridge of above-mentioned technical proposal, push-and-pull head compresses the circular cone endoporus of interior support set first during work, makes
Each interior support set unit of interior support set outwards struts respectively, then promotes corresponding each clamping section respectively by interior support set unit again
Unit outwards struts respectively, then the clamping of clamping section it is cylindrical be pointed to clamp cylindrical inner hole of workpiece be clamped.Above-mentioned
In clamping process, the endoporus of interior support set instead of the clamping section circular cone endoporus of the prior art, even if the hole size of workpiece is very big,
The clamping excircle dimension of clamping section is big, but the size of circular cone endoporus can remain unchanged, so push-and-pull head, the size of push-pull rod
Can be constant, so as to ensure the related components generalization that supporting interior Bloated tight cartridge uses, reduce inventory cost and simply manage.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is the structure diagram of the utility model,
Fig. 2 is the right view of Fig. 1.
Embodiment
As shown in the figure, the interior Bloated tight cartridge for large aperture Workpiece clamping of the utility model, by the clamping of integrative-structure
Portion 3, location division 2 and flange portion 1 form, and clamping section 3 along the circumferential direction opens up six slit shearing grooves 4, six slit shearing grooves 4
Clamping section 3 is divided into the clamping section unit of six valve independences, the clamping section 3, which has, clamps cylindrical 31 and Cylinder inner bore 32, circle
Column endoporus 32 is equipped with interior support set 5, the cylindrical matching Cylinder inner bore 32 of interior support set 5, and the endoporus of interior support set 5 is set with circular cone
Meter, interior support set 5 are along the circumferential direction divided into the interior support set unit of six valve independences and are located remotely from each other, and are located remotely from each other distance and are more than institute
The width of slit shearing groove 4 is stated, clamping section unit is corresponded and is fixedly connected with interior support set unit.
Claims (2)
