Abstract
The utility model discloses the interior Bloated tight cartridge clamped for ladder bore work, 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 cylindrical clamping pin for being equipped with two kinds of different lengths of clamping of the clamping section, short clamping pins position is in outer position, and the long pins position that clamps is in inner position.The utility model is exclusively used in the elastic clamping of ladder bore work, simple in structure, improves clamping reliability.
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 if the endoporus of workpiece is ladder endoporus, then the clamping of clamping section is cylindrical
One end of inner hole of workpiece can only be clamped, so clamping is unreliable, workpiece easily occurs and loosens phenomenon.
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 bullet for being exclusively used in ladder bore work
Property clamp, it is simple in structure, improve the interior Bloated tight cartridge of clamping reliability.
The utility model is adopted the following technical scheme that to complete：
The interior Bloated tight cartridge clamped for ladder bore work, by the clamping section of integrative-structure, location division and flange portion group
Into clamping section along the circumferential direction opens up a plurality of slit shearing groove, and clamping part is cut into more valve independences by a plurality of slit shearing groove
Clamping section unit, it is characterised in that：The cylindrical clamping pin for being equipped with two kinds of different lengths of clamping of the clamping section, short clamping pins position
In outer position, the long pins position that clamps is in inner position.
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 length clamp pin and make circumference stagger setting on six valve clamping section units.
The head fixed setting elastic rubber fitting for clamping pin.
Using the interior Bloated tight cartridge of above-mentioned technical proposal, the cylindrical clamping pin for being equipped with two kinds of different lengths of clamping of clamping section
To be directed to the ladder endoporus both ends of workpiece respectively, so when collet is clamped inner hole of workpiece, the long pin that clamps acts on work
The big nose end of part ladder endoporus is simultaneously clamped, and the short pin that clamps then acts on the small bore end of workpiece ladder endoporus and clamped,
So greatly improve clamping reliability.In addition, there is deviation to eliminate when length pin simultaneously clamps on workpiece ladder endoporus, pin is clamped
There is provided elastic rubber fitting to realize elastic clamping on head, make clamping effect more preferable.
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 being used for ladder bore work and clamping of the utility model, by the folder of integrative-structure
Tight portion 3, location division 2 and flange portion 1 form, and clamping section 3 along the circumferential direction opens up six slit shearing grooves 7, six slit shearings
Clamping section 3 is divided into the clamping section unit of six valve independences by groove 7, and the clamping of the clamping section 3 is cylindrical to be equipped with two kinds of different lengths
Clamping pin, short clamping pin 5 be located at outer position, and the long pin 4 that clamps be located at inner position, and the length, which clamps, sells in the clamping of six valves
Make circumference stagger setting, the head fixed setting elastic rubber fitting 6 for clamping pin on portion's unit.So when collet is to workpiece A's
When endoporus is clamped, the long pin 4 that clamps acts on the big nose end A1 of workpiece ladder endoporus and is clamped, and short clamping pin 5 is then made
For workpiece ladder endoporus small bore end A2 and clamped, so greatly improving clamping reliability.
