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 the Ultraprecision Machining field, relate to a kind of polishing tool, especially relate to a kind of air bag polishing head that is used for the gasbag-type polishing.
Background technology
The gasbag-type polishing is a kind of finishing method of novelty, very is fit to the polishing of aspherics eyeglass.This technology is in development period both at home and abroad at present.The main spherical envelope with certain inflation pressure that adopts of gasbag-type polishing is polished processing as polishing tool.Compare with traditional polishing tool, the gasbag-type polishing technology can guarantee that not only rubbing head and polished surface of the work anastomose property are good, and can be through regulating pressure, the surface quality of control polishing efficiency and polished workpiece.Thereby be a kind of aspheric surface polishing method that has development potentiality.
At present, in gasbag-type polishing processing, because desired polishing efficiency of each process segment is all different with workpiece surface quality.So,, need to change the air bag internal pressure in the different phase of polishing processing.(Gao Bo, Yao Yingxue thank to outline to Gao Bo etc.; Yuan Zhejun, Liu Yan. the development of air bag polishing tool and characteristic test [J]. modern Manufacturing Engineering, 2004 (10) .) point out; Behind the airbag aeration of existing air bag polishing head, the deflection of air bag is big, especially is easy to generate axial deformation.The stressed deformation principle sketch map of air bag is referring to Fig. 3 during the existing air bag polishing head work that is used for the gasbag-type polishing; In Fig. 3, A indicates the zone and is the axial deformation district, and B indicates the zone and is the air bag deformed area; Because the bag material elastic modelling quantity is less, so B zone, inflation back can produce deformation.And the a-quadrant is stressed centrostigma, receives tension and is easy to generate axial deformation.Be prone to like this cause add position error increasing in man-hour, reduce machining accuracy.In addition, existing air bag polishing head adopts the screw lock structure to fix more, this not only mounting or dismounting trouble; And because each screw lock power can not guarantee just the same; Therefore can cause rubbing head each several part unbalance stress, thereby cause position error to strengthen easily, influence machining accuracy.
Summary of the invention
The objective 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 when the air bag internal pressure changes, but positioning accuracy, significantly improve the air bag polishing head that gasbag-type polishes that is used for of machining accuracy.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The present invention includes a connector, spherical bonnet and polishing material layer, the openend of spherical bonnet is connected with the axle connector, and the polishing material layer adheres to spherical elastic outer layer surface; Its characteristics are; Spherical bonnet 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 said spherical bonnet 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.Said spherical stainless steel substrates can be the punch forming part.
The openend of said spherical bonnet is connected with the axle connector; Preferably the openend of spherical bonnet is affixed through bonnet cover for seat, resilient sleeve and lock sleeve and axle connector; Said bonnet cover for seat is enclosed within on the connector; The openend of spherical bonnet is enclosed within on the bonnet cover for seat, and resilient sleeve is enclosed within on the openend outer wall of spherical bonnet, and lock sleeve compresses spherical bonnet through being threaded with the axle connector.Said bonnet cover for seat can be stainless steel gas softgel shell cover for seat.Said lock sleeve excircle preferably is provided with 4 deep gouges that are uniformly distributed with, and 4 deep gouges are used for spanner to be installed and removed the air bag polishing head, very convenient.
The thickness of said 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.
Compare with prior art, the present invention has following outstanding advantage:
Because the spherical elastic outer layer of spherical bonnet 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 air bag polishing head is inflated effectively.Because said bonnet cover for seat can be stainless steel gas softgel shell cover for seat, can effectively reduce the axial deflection of air bag polishing head like this.Because lock sleeve compresses spherical bonnet through being threaded with the axle connector; This fixing means has been simplified the fixed form that loaded down with trivial details glue bonds and screw lock matches; Make the mounting or dismounting of gasbag-type rubbing head convenient, reduce the influence that position error is brought, improved machining accuracy.
