Cause part process cycle too long, the parts product unstable quality of processing, and the stronger experience for relying on operating technology personnel；Two
It is that machining deformation is controlled by internal stress is cancelled out each other in part process method, this control method can only be to tool
There is the part processing of double-sided symmetrical structure just effective, applicability is narrow, and the processing essence of part can not be completely secured
Degree, the overproof problem of part size are serious；Third is that removing part deformation by the method that part processes post-equalization, i.e., in intermediate process
Increase correcting process as one sees fit or use special tooling, the method for this correction is become by the external method removal for applying stress
Shape, thus the serious influence inside parts materials microstructure of meeting, while often will appear crackle in correction course, stress distribution is not
Equal situation seriously affects the quality of part.Above-mentioned common drawback be it is time-consuming and laborious, the processing of thin-wall barrel is not closed
Suitable Auxiliary support, bad adaptability, the easy stress deformation of workpiece, machining accuracy are not easy to guarantee.
Utility model content

Sucker group is connect with curved support plate, for being adsorbed on workpiece surface, is extracted air by negative pressure pump, is enhanced sucker to thin wall cylinder
The pretightening force of part.
Further, the curved support plate installs the sucker group of four universal connections, the disk chamber of sucker by tubule with
Negative pressure pump connection.
The adjustable Support Position of support base, the support arm being connected with support base are high by adjusting angle control
Degree.
Further, the clamp body is equipped with three to four group support bases.
Further, it is equipped with spring in the vacuum chuck group, plays damping effect.
Inner hole stud base is embedded in vacuum chuck coupler bore and forms transfer, with nitrile rubber sucker suction in thin-walled
On cylinder part.
Further, the curved support plate can realize swinging up and down for certain angle, realize 0 °~20 ° of taper of thin-walled
Cylinder part Milling Process.
The utility model has the advantages that
A kind of vacuum chuck clamp standoff type fraise jig device for thin-wall barrel of the utility model can be realized pair
Various sizes of thin-wall barrel carries out the effect apart from Auxiliary support that is adjustable, highly adjustable, adapting to certain taper, versatility
By force, structure is simple.The utility model provides enough vacuum adsorption forces using pneumatic mode, securely and reliably, applied widely, reduces
The machining deformation of workpiece during high-speed milling, to guarantee the machining accuracy of thin-wall barrel.
