Description
Technical field
The invention belongs to a kind of vapor seal drawing liquid non-contact type hydrojet grinding wheel for numerical control relief polishing that relates in the optics cold processing technique field.
Background technology
In optical technical field, to forming the optical mirror slip of all kinds of optical systems, as lens, level crossing, spherical mirror, all kinds of aspherical mirrors etc., all need by the specification requirement of optical design roughly grind, fine grinding, correct grinding, polishing etc. grind and make, this process is referred to as optics cold working at optics circle.
The cold worked machine tool of optics all has bistrique, is used for optical mirror slip is ground manufacturing processing.It is smaller than the bistrique size of machine glazed finish that ordinary circumstance is used for the bistrique of numerical control polishing, and all be solid bistrique.
The prior art the most approaching with the present invention is the patent of invention of Changchun Institute of Optics, Fine Mechanics and Physics, CAS in the application of 2004 years, application number is 200410011215.X, and denomination of invention is " a kind of numerical control polishing with contactless hydrojet bistrique ".As shown in Figure 1, comprise that hollow drive shaft 1, hollow bistrique 2, bistrique cavity 3, polishing fluid portal 4.Hollow drive shaft 1 is perpendicular to hollow bistrique 2, both are integral piece, the bistrique cavity 3 of the hollow and hollow bistrique 2 of hollow drive shaft 1 communicates, the polishing fluid that distributing on the working face of hollow bistrique 2 portals 4, it is big that the hole in centre is being followed in distribution, excessive hole, past more edge is more little rule just, and portal 4 distribution of polishing fluid can be regular, also can be irregular.
The subject matter that this hydrojet bistrique exists is: the polishing fluid that process is used can not in time be collected, the non-polishing area of the processed optical element of meeting erosion, influence polishing precision.
Summary of the invention
In order to overcome the defective that prior art exists, the objective of the invention is to prevent polishing fluid diffusion in the process, the non-polishing area of the processed optical element of erosion improves the control to optical element polishing precision.
The technical problem to be solved in the present invention is: a kind of vapor seal drawing liquid non-contact type hydrojet grinding wheel for numerical control relief polishing is provided.The technical scheme of technical solution problem such as Fig. 2, shown in Figure 3: comprise that hollow drive shaft 5, bistrique axle sleeve 6, bistrique adapter sleeve 7, catch tray link 8, hollow bistrique 9, bistrique cavity 10, polishing fluid catch tray 11, first air admission hole 12, the first gas curtain groove 13, second air admission hole 14, the second gas curtain groove 15, drawing liquid hole 16, collecting tank 17, polishing fluid portal 18.
Operation principle explanation: keep certain clearance between bistrique and the processed optical element, be in contactless state, with certain pressure with polishing fluid from the ejection of portalling of the polishing fluid of bistrique, be full of the gap between bistrique and the processed optical element, what of the local removal amount of polishing on the processed optical element are relevant with the size distribution that the velocity of rotation and the polishing fluid of bistrique portal with uniformity, follow bistrique centre polishing fluid and portal greatly, the past more edge excessive polishing liquid more little regularity of distribution of portalling.The polishing fluid catch tray is connected by bistrique adapter sleeve and catch tray link and bistrique axle sleeve, can carry out translation and swing with bistrique, but not sway with bistrique.The high-speed gas that is produced by air pump enters the first gas curtain groove from first air admission hole, and the gap between polishing fluid catch tray and hollow bistrique forms gas curtain and seals, and prevents that polishing fluid from overflowing from the gap.Can be for improving the sealing gland performance along the first gas curtain groove a plurality of air admission holes of evenly arranging.The high-speed gas that is produced by air pump enters the second gas curtain groove from second air admission hole, and the gap between hollow bistrique and processed optical element forms gas curtain and seals, and prevents that polishing fluid is in processed optical element diffusion into the surface.Can be for improving the sealing gland performance along the second gas curtain groove a plurality of air admission holes of evenly arranging.By air seal set, used polishing fluid is constrained in the gap between bistrique and the processed optical element, and the polishing fluid after external drawing liquid pump uses these by drawing liquid hole and collecting tank is in time extracted out also and collected.Can be for improving the drawing liquid ability along collecting tank a plurality of drawing liquids hole of evenly arranging.
Good effect of the present invention: adopt contactless polishing mode, avoided processed optical element generation of local stress on the workpiece in process, prevented any diffusion of polishing fluid by air seal set on the polishing fluid catch tray and pumping device, and in time used polishing fluid is collected, prevent the non-polishing area of the processed optical element of polishing fluid erosion, how much can accurately effectively being controlled of the local polishing removal amount of processed optical element, the uniformity of the local removal amount of polishing is guaranteed, and has improved the quality of polishing.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is a main TV structure schematic diagram of the present invention;
Fig. 3 is the plan structure schematic diagram of Fig. 2.
The specific embodiment
The present invention presses Fig. 2 and structure shown in Figure 3 is implemented.Wherein the material of hollow drive shaft 5, bistrique axle sleeve 6, bistrique adapter sleeve 7, catch tray link 8, hollow bistrique 9, polishing fluid catch tray 11 adopts stainless steel.Hollow drive shaft 5 and hollow bistrique 9 are one hollow object or two parts for cooperating hollow object, and alleged cooperation is that two parts stick with glue and connect or use threaded engagement.Bistrique axle sleeve 6 adopts bolting or screw thread to be connected with bistrique adapter sleeve 7.Catch tray link 8 is a welding manner with bistrique adapter sleeve 7 and polishing fluid catch tray 11 junctions.The size of polishing fluid catch tray 11 is relevant with the size of hollow bistrique 9, and generally adopt hollow bistrique size 2 times, the gap between polishing fluid catch tray 11 and the hollow bistrique 9 is about 2mm.The size of first air admission hole 12, the first gas curtain groove 13, second air admission hole 14 and the second gas curtain groove 15 is determined according to the flow velocity and the flow of hollow bistrique 9 ejection polishing fluids, to guarantee that gas curtain sprays the pressure of gas and the pressure of bistrique ejection polishing fluid is complementary.The size of drawing liquid hole 16 and collecting tank 17 is determined according to the flow of hollow bistrique 9 ejection polishing fluids, is complementary with the polishing fluid spray volume of guarantor unit's hollow bistrique 9 in the time and the drawing liquid amount of polishing fluid catch tray 11.
