Abstract
The utility model belongs to laser cutting device, more particularly to a kind of axial rotary sealing structure of laser cutting chuck.Chuck rotation axis is to sealing structure comprising chuck, and the air intake assembly that is connected on main shaft, it is characterised in that：The air intake assembly includes the inner sleeve being set on main shaft, inside it is arranged with the conveying gas circuit being connected to chuck, further include being set in housing on interior set, bearing is equipped between inner sleeve and housing, outer put on puts on the guiding gas circuit equipped with being connected to intake interface equipped with intake interface outside, and extraneous gas enters from intake interface, by being oriented to gas circuit to conveying gas circuit, eventually enter into inside chuck.The utility model devises a kind of axial admission sealing structure of the air spider of laser cutting device.
Description
Technical field
The utility model belongs to laser cutting device, more particularly to the axial rotary sealing knot of a kind of laser cutting chuck
Structure.
Background technology
The chuck that existing laser cutting machine uses mainly has hand chuck, end face seal chuck and oild chuck；
1, hand chuck needs manual locking, time-consuming and laborious, under efficiency is relatively low；
2, the Pneumatic end-face sealing of some existing laser cutting machine chucks, assemble cumbersome, usage time is not grown；
3, the reaction of oild chuck is more blunt, is easy folder bad workpiece.
Invention content
For problems of the prior art, the utility model devises a kind of air spider of laser cutting device
Axial admission sealing structure.
The technical solution of the utility model is as follows：
Chuck rotation axis is to sealing structure comprising chuck, and the air intake assembly that is connected on main shaft, feature exist
In：The air intake assembly includes the inner sleeve being set on main shaft, is inside arranged with the conveying gas circuit being connected to chuck, further includes set
Be located at housing on interior set, be equipped with bearing between inner sleeve and housing, it is described it is outer put on equipped with intake interface, put on outside equipped with
The guiding gas circuit of intake interface connection, extraneous gas enter from intake interface, by being oriented to gas circuit to conveying gas circuit, eventually enter into
Inside chuck.
Sealing ring is equipped between the housing and chuck.
The side of the inner sleeve and housing is equipped with fixed cover board, and fixed cover board is connected by screw to be put on inside.
In conclusion the utility model has the advantages that：
The utility model conveys power gas by the way of axial admission into chuck, and sealing structure is simple, installation side
Just, the problem of it is serious to overcome sealing ring aging existing for end face air inlet in the prior art, is easy gas leakage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged diagram of inlet seal structure；
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, chuck rotation axis is to sealing structure comprising chuck 1, chuck is for pressing from both sides workpiece
Tightly, its in the present embodiment is clamped workpiece by gas effect, and the air intake assembly 3 being connected on main shaft 2, described
Air intake assembly 3 includes the inner sleeve 30 being set on main shaft, and inner sleeve 30 is equipped with the conveying gas circuit 301 being connected to chuck, further includes set
The housing 31 being located in inner sleeve 30, is equipped with bearing 32 between inner sleeve 30 and housing 31, i.e. inner sleeve rotates relative to housing, makes
With inner sleeve in the process as main shaft rotates together, the housing 31 is equipped with intake interface 310, and housing 31 is equipped with and air inlet
The guiding gas circuit that interface 310 is connected to, extraneous gas enter from intake interface, by being oriented to gas circuit to conveying gas circuit, eventually enter into
Inside chuck.
The air spider of the utility model accesses for axial gas, devises a kind of sealing structure of axial admission, external
Gas enters from the intake interface of housing, then by being oriented to gas circuit, eventually enters into the conveying gas circuit of inner sleeve, conveying gas circuit outflow
Enter in chuck afterwards, the utility model conveys power gas by the way of axial admission into chuck, and sealing structure is simple, pacifies
Dress is convenient, and it is serious to overcome sealing ring aging existing for end face air inlet in the prior art, the problem of being easy gas leakage.
Sealing ring 4 is equipped between the housing 31 and chuck 1, it is close between the sealing ring raising housing and chuck of setting
Envelope avoids gas from going out outflow from bearing, ensure that the stabilization of admission pressure.
The side of the inner sleeve 30 and housing 31 is equipped with fixed cover board 33, and fixed cover board 33 is connected by screw in inner sleeve
On, the fixation cover board of setting is positioned for externally putting on the bearing of setting, is avoided the problem that bearing falls off, is also improved
The aesthetics of whole equipment.
In conclusion the utility model has the advantages that：
The utility model conveys power gas by the way of axial admission into chuck, and sealing structure is simple, installation side
Just, the problem of it is serious to overcome sealing ring aging existing for end face air inlet in the prior art, is easy gas leakage.
