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 outer expansion chuck.
Background technology
Outer Bloated tight cartridge be used for excircle of workpiece clamping, be it is a kind of realizes automation endoporus, end face processing commonly use
Instrument.Outer Bloated tight cartridge is made of the clamping section of integrative-structure, connection part and guide part, and operation principle is by clamping section
The compression of outer conical surface, makes the clamping section for opening up slit shearing groove produce elastic deformation, the clamping endoporus of clamping section is pointed to press from both sides
The excircle of workpiece of tight endoporus is clamped.In the prior art, a kind of outer Bloated tight cartridge can only correspond to a kind of workpiece, for not similar shape
The workpiece of shape size is, it is necessary to configure many outer Bloated tight cartridges；In addition, for the cylindrical workpiece for cone, it is necessary to clamp endoporus
Also it is taper hole, since the depth for clamping endoporus is shallower, so processing taper hole is difficult, the design of outer Bloated tight cartridge can become very multiple
It is miscellaneous；In addition, for proof strength and persistently elastic, outer Bloated tight cartridge generally uses metal material, this is not suitable for some particular/special requirements
The clamping of workpiece.
The content of the invention
In view of the deficiency of background technology, the purpose of this utility model, which aims to provide one kind, can be suitable for various different workpieces
Clamping, it is simple in structure, reduce collet configuration multi-functional outer Bloated tight cartridge.
The utility model is adopted the following technical scheme that to complete：
Multi-functional outer Bloated tight cartridge, is made of the clamping section of integrative-structure, connection part and guide part, and clamping section has cylindrical
The conical surface and clamping endoporus, clamping section along the circumferential direction open up three slit shearing grooves, and three slit shearing grooves split clamping section
Into the clamping section unit of three valve independences, slit shearing groove is through clamping section whole length until outside guide part, guide part
Circle is equipped with guide chute, and the endoporus of guide part is equipped with threaded connection hole, it is characterised in that：The clamping endoporus is equipped with gripping sleeve,
The cylindrical matching of gripping sleeve clamps endoporus, the endoporus matching excircle of workpiece of gripping sleeve, and gripping sleeve is along the circumferential direction divided into three
The gripping sleeve unit of valve independence, gripping sleeve unit are corresponded with clamping section unit and are fixedly connected by screw.
The outboard end of the gripping sleeve has flange circle, and flange circle is also cut into three independent valves, flange with gripping sleeve
Enclose the outer end face close to clamping section to set, the mounting hole of the screw, the clamping corresponding with mounting hole are machined with flange circle
The outer end face in portion is equipped with threaded hole.
Using the outer Bloated tight cartridge of above-mentioned technical proposal, advantageous effects are：1. clamp endoporus to be arranged with clamping
Meter, by selecting different gripping sleeves to rapidly adapt to different workpieces, reduces collet configuration；2. gripping sleeve is as individual part,
Processing taper hole is very convenient, and then the structure of outer Bloated tight cartridge becomes simple；3. gripping sleeve can arbitrarily select material to be pressed from both sides without influencing
The performance of head, can be adapted to the clamping of particular/special requirement workpiece.
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 multi-functional outer Bloated tight cartridge of the utility model, by the clamping section 1 of integrative-structure, connection part 2 and leads
Formed to portion 3, clamping section 1 has outer conical surface 4 and clamps endoporus 5, and clamping section 1 along the circumferential direction opens up three slit shearing grooves
9, clamping section 1 is divided into the clamping section unit of three valve independences by three slit shearing grooves 9, and slit shearing groove 9 is whole through clamping section 1
A length is until close to guide part 3, and the cylindrical of guide part 3 is equipped with guide chute 11, and the endoporus of guide part 3 is equipped with threaded connection hole
10, the clamping endoporus 5 is equipped with gripping sleeve 6, and gripping sleeve 6 can use the material different from collet, the cylindrical matching folder of gripping sleeve 6
Tight endoporus 5, the endoporus matching excircle of workpiece of gripping sleeve 6, the endoporus of gripping sleeve 6 is conical bore, and gripping sleeve 6 is along the circumferential direction divided
The gripping sleeve unit of three valve independences is cut into, gripping sleeve unit is corresponded with clamping section unit and is fixedly connected by screw 8.Institute
Stating the outboard end of gripping sleeve 6 has a flange circle 7, and flange circle 7 is also cut into three independent valves with gripping sleeve 6, flange circle 7 close to
The outer end face of clamping section 1 is set, and the mounting hole of the screw 8, the clamping section 1 corresponding with mounting hole are machined with flange circle 7
Outer end face be equipped with threaded hole.
