The air bag polishing head comprises a shaft connector, a spherical-crown-shaped air bag shell and a polishing material layer, wherein the open end of the spherical-crown-shaped air bag shell is fixedly connected with the shaft connector; and the polishing material layer is fixedly bonded on the surface of a spherical-crown-shaped elastic outer layer. The air bag polishing head is characterized in that the spherical-crown-shaped air bag shell is provided with a spherical-crown-shaped elastic outer layer and a spherical-crown-shaped elastic inner layer; the elastic modulus of the spherical-crown-shaped elastic inner layer is higher than that of the spherical-crown-shaped elastic outer layer; and the spherical-crown-shaped elastic outer layer is directly molded on the surface of the spherical-crown-shaped elastic inner layer through injection molding, and is fixedly connected with the spherical-crown-shaped elastic inner layer.
Description
Technical field
The invention belongs to Ultraprecision Machining field, relate to a kind of polishing tool, especially relate to a kind of air bag polishing head for gasbag-type polishing.
Background technology
Gasbag-type polishing is a kind of finishing method of novelty, the polishing of very applicable aspheric optical lens.This technology is in development period both at home and abroad at present.Gasbag-type polishing mainly adopts the spherical envelope with certain inflation pressure to carry out polishing as polishing tool.Compared with traditional polishing tool, gasbag-type polishing technology not only can ensure rubbing head and polished surface of the work anastomose property good, and can, by regulating pressure, control the surface quality of polishing efficiency and polished workpiece.Because of but the extremely potential aspheric surface polishing method of one.
At present, in gasbag-type polishing, because desired polishing efficiency of each process segment is all different with workpiece surface quality.So, in the different phase of polishing, need to change inside air bag pressure.(the Gao Bo such as Gao Bo, Yao Yingxue, thank to outline, Yuan Zhejun, Liu Yan. the development of air bag polishing tool and characteristic test [J]. modern Manufacturing Engineering, 2004 (10) .) point out, after the airbag aeration of existing air bag polishing head, the deflection of air bag is large, especially easily produces axial deformation.When the work of the existing air bag polishing head for gasbag-type polishing, the stressed deformation principle schematic diagram of air bag is referring to Fig. 3, in Fig. 3, region that A indicates is axial deformation district, and region that B indicates is air bag deformed area, because bag material elastic modelling quantity is less, therefore B region can produce deformation after inflation.And a-quadrant is stressed centrostigma, under tension effect easily produces axial deformation.Easy like this causing adds position error increasing in man-hour, reduces machining accuracy.In addition, existing air bag polishing head adopts screw lock structure to be fixed more, this not only mounting or dismounting trouble, and because each screw lock power can not ensure just the same, therefore can cause rubbing head each several part unbalance stress, thereby easily cause position error to strengthen, affect machining accuracy.
Summary of the invention
The object of the invention is to overcome the shortcoming that existing air bag polishing head exists, provide that a kind of the deflection of air bag is little in the time of inside air bag pressure change, can positioning precision, significantly improve the air bag polishing head for gasbag-type polishing of machining accuracy.
For achieving the above object, the present invention adopts following technical scheme:
The present invention includes axle connector, spherical air bag shell and the polishing material bed of material, the openend of spherical air bag shell and axle connector are connected, and the polishing material bed of material adheres to spherical elastic outer layer surface; Its feature is, spherical air bag shell is provided with spherical elastic outer layer and spherical elastic inner layer, the elastic modelling quantity of spherical elastic inner layer is greater than the elastic modelling quantity of spherical elastic outer layer, the direct injection mo(u)lding of spherical elastic outer layer is on spherical elastic inner layer surface, and spherical elastic outer layer and spherical elastic inner layer are fixed.
The spherical elastic outer layer of described spherical air bag shell can be spherical rubber layer, and spherical elastic inner layer can be spherical stainless steel substrates, and the direct injection mo(u)lding of spherical rubber layer is on spherical stainless steel substrates surface.Described spherical stainless steel substrates can be punch forming part.
The openend of described spherical air bag shell and axle connector are connected, preferably the openend of spherical air bag shell is affixed by air bag shell block cover, resilient sleeve and lock sleeve and axle connector, described air bag shell block cover is enclosed within on axle connector, the openend of spherical air bag shell is enclosed within air bag shell block and puts, resilient sleeve is enclosed within on the openend outer wall of spherical air bag shell, and lock sleeve compresses spherical air bag shell by being threaded with axle connector.Described air bag shell block cover can be stainless steel gas softgel shell cover for seat.Described lock sleeve excircle is preferably provided with 4 uniform deep gouges, and 4 deep gouges are installed and removed air bag polishing head for spanner, very convenient.
The thickness of described spherical stainless steel substrates can be 0.1 ~ 0.3mm; The thickness of spherical rubber layer can be 3～5mm; The thickness of stainless steel gas softgel shell cover for seat can be 3 ~ 5mm.
Compared with the prior art, the present invention has following outstanding advantages:
Because the spherical elastic outer layer of spherical air bag shell can be spherical rubber layer, spherical elastic inner layer can be spherical stainless steel substrates, the elastic modelling quantity of spherical like this stainless steel substrates is more much bigger than spherical rubber layer, so spherical stainless steel substrates can reduce the deflection after the inflation of air bag polishing head effectively.Because described air bag shell block cover can be stainless steel gas softgel shell cover for seat, can effectively reduce like this axial deflection of air bag polishing head.Because lock sleeve compresses spherical air bag shell by being threaded with axle connector, this fixing means has been simplified the fixed form that loaded down with trivial details glue bonds and screw lock matches, make gasbag polishing tool mounting or dismounting convenient, reduce the impact that position error is brought, improved machining accuracy.
