Abstract
The utility model discloses a head is gripped to interior expanding comprises clamp part, location portion and flange portion, its characterized in that: clamp part and the lug connection of flange portion, location portion movable sleeve is established at the clamp part excircle, and location portion passes through screw fixed connection in flange portion, and the free end that the clamp part exposes location portion sets up the circular cone hole and presss from both sides tight excircle, and the clamp part free end is seted up three along the circumferencial direction and is vertically cut off the groove, and the length of vertically cutting off the groove is greater than the whole length of pressing from both sides tight excircle, the circular cone hole of clamp part free end is equipped with annular shallow slot and axial shallow slot, and annular shallow slot is equipped with many at the axial direction of circular cone hole, and the axial shallow slot is equipped with many at the circumferencial direction of circular cone hole, axial shallow slot perpendicular to annular shallow slot, and the axial shallow slot feeds through annular shallow slot and extend to the outer terminal surface of clamp part free end. The utility model is used for the elastic clamping of work piece hole presss from both sides the tightly difficult wearing and tearing of of high quality, chuck circular cone hole, improves life, can prevent that the chuck excessively warp simultaneously.
Description
Technical field
This utility model relates to a kind of collet, is specifically related to the collet of a kind of interior expansion chuck.
Background technology
Interior Bloated tight cartridge, for the clamping of inner hole of workpiece, is a kind of to realize automatization's cylindrical, the common tool of end face processing.The interior Bloated tight cartridge of prior art is made up of the clamping section of integrative-structure, location division and flange portion, clamping section is for the clamping of inner hole of workpiece, location division is for the location of workpiece end face, flange portion is for the installation of chuck, operation principle is the compression by the circular cone endoporus to clamping section, making the clamping section offering slit shearing groove produce outside elastic deformation, the clamping cylindrical of clamping section is pointed to clamp the inner hole of workpiece of cylindrical and is clamped.But, in actual application, it is primarily present following shortcoming: 1. work is carried out Quick-clamped owing to realizing, clamping section to be typically designed to be easily deformed, but owing to clamping section, location division are structure as a whole, it is restricted so the outside elastic deformation of clamping section is more difficult, is therefore easily caused excessive deformation, affect the service life of chuck；2. the circular cone endoporus of clamping section have processing iron filings fall above, easily produce abrasion when circular cone endoporus is compacted, and the abrasion of circular cone endoporus can affect clamping quality, until having influence on the service life of chuck.
Summary of the invention
In view of the deficiency of background technology, the purpose of this utility model aims to provide a kind of elastic clamping for inner hole of workpiece, and quality is good, circular cone endoporus is the most easy to wear in clamping, improve service life, is prevented from the interior Bloated tight cartridge of excessive deformation simultaneously.
This utility model has adopted the following technical scheme that:
Bloated tight cartridge in a kind of, by clamping section, location division and flange portion composition, it is characterized in that: clamping section is directly connected to flange portion after extension design, location division is provided with Cylinder inner bore and is movably set in clamping section cylindrical by Cylinder inner bore, location division is fixedly connected in flange portion by screw, clamping section is exposed the free end of location division and is arranged circular cone endoporus and clamping cylindrical, clamping section free end along the circumferential direction offers three slit shearing grooves, the length of slit shearing groove is more than the whole length of clamping cylindrical, the top of slit shearing groove is positioned at the outer face of clamping section free end, end connects circular hole.
The circular cone endoporus of clamping section free end is provided with annular shallow slot and axial shallow slot, annular shallow slot is provided with a plurality of at the axial direction of circular cone endoporus, axially shallow slot is provided with a plurality of at the circumferencial direction of circular cone endoporus, axially shallow slot is perpendicular to annular shallow slot, and annular shallow slot is connected and extends to the outer face of clamping section free end by axial shallow slot.
Use the outer Bloated tight cartridge of technique scheme; Advantageous Effects is: 1. clamping section uses Split type structure with location division; location division is provided with Cylinder inner bore and is movably set in clamping section cylindrical by Cylinder inner bore; so; gap between Cylinder inner bore and clamping section cylindrical both ensure that the elastic deformation of clamping cylindrical; the deflection of clamping cylindrical can be limited again, thus play the protective effect preventing chuck excessive deformation, it is ensured that chuck service life；2. the circular cone endoporus of clamping section is provided with the annular shallow slot mutually communicated and axial shallow slot, can accommodate the processing iron filings falling circular cone bore area, thus avoid circular cone endoporus compacted time abrasion, it is ensured that clamping quality, improve chuck service life.
Accompanying drawing explanation
This utility model has a drawings described below:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
As shown in the figure, Bloated tight cartridge in one of the present utility model, by clamping section 3, location division 2 and flange portion 3 form, clamping section 3 is directly connected to flange portion 1 after extension design, location division 2 is provided with Cylinder inner bore 21 and is movably set in clamping section 3 cylindrical by Cylinder inner bore 21, location division 2 is fixedly connected in flange portion 1 by screw, clamping section 3 is exposed the free end of location division 2 and is arranged circular cone endoporus 32 and clamping cylindrical 31, clamping section 3 free end along the circumferential direction offers three slit shearing grooves 6, the length of slit shearing groove 6 is more than the whole length of clamping cylindrical 31, the top of slit shearing groove 6 is positioned at the outer face of clamping section 3 free end, end connects circular hole 7；The circular cone endoporus 32 of clamping section 3 free end is provided with annular shallow slot 4 and axial shallow slot 5, annular shallow slot 4 is provided with three at the axial direction of circular cone endoporus 32, axially shallow slot 5 is provided with four at the circumferencial direction of circular cone endoporus 32, axially shallow slot 5 is perpendicular to annular shallow slot 4, and annular shallow slot 4 is connected and extends to the outer face of clamping section 3 free end by axial shallow slot 5.
