A kind of float glass process polishing self adaptation spring chuck
One, technical field
The invention belongs to a kind of self adaptation spring chuck that relates in the optics cold processing technique field.
Two, technical background
At optical technical field, to forming the optical mirror slip of all kinds of optical systems, as lens, speculum, level crossing, spherical mirror, all kinds of aspherical mirrors etc., all to roughly grind by the specification requirement of optical design, fine grinding, correct grinding, polishing etc. grind and make, this process is referred to as optics cold working at optics circle.The float glass process polishing is the cold worked a kind of polishing mode of optics.
Processed optical mirror slip in the optics cold working all will adopt anchor clamps fixedly to process.Age in the past, the anchor clamps of general float glass process polishing usefulness do not have elasticity, it is hard connection, being Science Press with the most approaching prior art of the present invention publishes " advanced Optical manufacture technology " book (Yang Li chief editor) P226~230 page in calendar year 2001, anchor clamps are used in the float glass process polishing of record, as shown in Figure 1: comprise workpiece spindle 1, terminal pad 2, workpiece plate 3, bonded adhesives 4; Workpiece spindle 1 is perpendicular to terminal pad 2, both are connected rigidity, terminal pad 2 is parallel to workpiece plate 3, both are connected rigidity, bonded adhesives 4 is evenly coated on the working face of workpiece plate 3, in order to bonding processed optical mirror slip 5, the mill surface that the surface to be machined of processed optical mirror slip 5 should be below being positioned at it is parallel.
The subject matter that does not have flexible hard jockey to exist of this float glass process polishing usefulness is: workpiece spindle is difficult to accomplish vertical with processed optical lens surface, be difficult to also accomplish that workpiece spindle is vertical with the working face of mill, thereby the machined surface that just can not guarantee optical mirror slip and mill working face is parallel, can cause the polishing error of machined surface like this.
Three, summary of the invention
In order to overcome the defective of above-mentioned prior art, the objective of the invention is to accomplish to greatest extent the parallel of work piece surface and mill working face, raising quality of finish, a kind of self adaptation spring chuck of ad hoc meter.
The technical problem to be solved in the present invention is: a kind of float glass process polishing self adaptation spring chuck is provided.The technical scheme of technical solution problem as shown in Figure 2; Comprise workpiece spindle 6, terminal pad 7, workpiece plate 8, bellows 9, bonded adhesives 10, workpiece plate 11, bonded adhesives 12; Workpiece spindle 6 is perpendicular to terminal pad 7, both are connected rigidity, and terminal pad 7 is parallel to workpiece plate 8, and both are connected rigidity, two end faces of bellows 9 are parallel, one of them end face is parallel with the working face of workpiece plate 8, and bonding with bonded adhesives 10 sealings, and another end face is top parallel with workpiece plate 11, and it is bonding with bonded adhesives 10 sealings, on the working face of workpiece plate 11, evenly scribble bonded adhesives 12, bonding processed optical mirror slip 13.
The operation principle explanation: the float glass process polishing is a kind of contactless Super-smooth Surface Polishing mode, processed optical mirror slip is fixed on and will keeps with mill micron-sized gap being arranged on the anchor clamps, be full of polishing fluid in the gap, mill is done relative planetary motion with the work piece surface, can carry out precise polished, the workpiece surface to be machined that requires anchor clamps to fix is parallel fully with the surface of mill, have only the workpiece spindle that will drive the anchor clamps rotation to be adjusted in theory and complete vertical the getting final product of mill, but the difficulty of this adjustment is very big, even the adjustment of workpiece spindle position is vertical fully to mill fully, on anchor clamps, be difficult to also accomplish that work piece is parallel fully with flour milling during fixation workpiece, the deviation that above factor causes can finally cause the work piece surface to be worn into the conical surface or mill is inclined to one side, face shape is damaged, analyze above-mentioned reason, designed the self adaptation spring chuck of bellows-type structure, driving the work piece surface at workpiece spindle does in the relative planetary motion process with mill, stressed big orientation bellows can compress, this has just guaranteed under the stressed different situation in where position in office, can both guarantee the parallel of work piece surface and mill surface, therefore, the self adaptation spring chuck can guarantee quality of finish.
Good effect of the present invention: the self adaptation spring chuck that has bellows, can regulate the work piece surface does in the relative planetary rotation process with mill, it is in office that where the position is because under the stressed different situation, can both guarantee the parallel of work piece surface and mill surface, thus the quality of finish of assurance work piece face shape.
Four, description of drawings
Fig. 1 is the structural representation of prior art, and Fig. 2 is a structural representation of the present invention, and Figure of abstract adopts Fig. 2.
Five, the specific embodiment
The present invention implements by structure shown in Figure 2, wherein workpiece spindle 6, terminal pad 7, the material of workpiece plate 8 adopts stainless steel, the material of bellows 9 adopts stainless steel or copper, the material adopting quartz glass of workpiece plate 11, the size of above-mentioned each part and intensity determine that according to the size of work piece bonded adhesives 10 and 12 adopts silica gel.
