Definitions
- the invention relates to a receiving chuck for optical components for fine grinding and / or polishing with a plurality of support elements made of elastic material for the components and an arrangement for supplying or removing air to the rear of the support element.
- Spherical convex or concave curved lenses are preferably provided as optical components.
- a receiving chuck of this type for single lens processing is known from DE 198 12 186 A1.
- the lens holder consists of a rotationally symmetrical base body with a recess into which a lens to be machined is inserted and which is sealed off on the other side with a rubber membrane.
- the rear side of the rubber membrane can be pressurized with compressed air through a central hole in the shaft of the receiving chuck.
- the rubber membrane then expands, lies on the lens and presses it evenly against the polishing tool. There is a flat contact, since both parts have the same radius of curvature.
- the lens By creating a negative pressure on the membrane surface, the lens can be sucked onto the membrane surface and brought into a hanging position.
- the hanging mount of the lens is therefore preferably selected so that its own weight supports the contact pressure to the polishing tool after the membrane has been aerated for the polishing process.
- the centrally supplied amount of compressed air can be individually adapted to the lens to be processed. For thinner lenses, where the ratio between
- Intake feed known with which support zones with different contact pressure can be generated in the membrane surface by the supply of differently regulated air pressures.
- intake feed described there an embodiment for the simultaneous intake of several lenses is also described.
- Such a feed has a base body and a support body connected to it.
- the support body is provided with a cap-shaped cover which is held on the base body by a surrounding ring. Symmetrical to the axis of rotation of the support body, several recesses are contained therein.
- the cap-shaped coating forms an elastic membrane on which the lenses to be processed lie with their central area.
- the inclusion of the lens as a whole is formed by an indentation in the cap-shaped coating which is adapted to the lens diameter.
- Each of the depressions in the support body is connected to the shaft of the base body by a separate air duct, the respective membrane parts of the coating being fixed in the depression and sealing them airtight.
- Compressed air can be applied to the remaining lower surface of the coating via a channel separated from the other air channels through the support body.
- support zones with different pressure can be generated within each lens support.
- the cover is complex in shape and requires complex assembly on the support body. While the air supply in the membrane parts can also be regulated individually, the local pressure build-up under the remaining surface of the coating cannot be influenced via the central air supply.
- the invention has for its object to provide a feed that allows multiple intake with the advantages of a single intake by using series membrane elements and is structurally simple.
- the recesses in the cover part can be prepared for commercially available elastic support elements with different dimensions. Fastening and sealing via an O-ring pressed into a groove allows easy assembly and also acts as an overpressure protection. Should air pressure unintentionally reach the membrane without a lens resting on it and a polishing tool being brought up to the lens, the support element is pressed out of the holder without being destroyed.
- the support elements in addition to a uniform contact pressure between the lens surface and the polishing tool, their relative movements to one another are also important.
- the support elements in a cylindrical holder, which is rotatably mounted in the recess of the cover part, an additional relative movement of the individual lenses on the common receiving chuck can be realized.
- the holder can be provided with a drive shaft which extends into the pot space of the base body and here is gearingly connected to the drive for the spindle shaft.
- Exemplary embodiments of the feed chuck are shown schematically in the drawing and are described in more detail with reference to the figures. Show:
- Fig.1 a feed chuck with firmly inserted in the cover part support elements and 2 shows a receiving chuck with support elements rotatably inserted into the cover part.
- the base body 1 contains a base body 1 with a spindle shaft 2, which is inserted into a machine spindle, not shown, for rotating the receiving chuck.
- the spindle shaft 2 is provided with a central bore 3, which is connected to a compressor-vacuum system for air supply, also not shown.
- the base body 1 has a peripheral edge 4, through which a cup-shaped space 5 is formed in the base body 1, which extends over the entire bottom surface of the base body 1.
- the cover part 6 On the edge 4 of the base body 1 there is a cover part 6 which is screwed to the base body 1 and closes the pot space 5 via an O-ring seal 7.
- the cover part 6 has a cylindrical recess 8.
- Such membrane parts 9 are available as series parts for individual lens exposures.
- the hat rim 10 engages in a groove 11 in the recess 8 and is pressed here firmly by an O-ring 12 onto the bottom of the recess 8.
- the area of the recess 8 lying below the membrane part 9 is connected in terms of flow via a bore 13 to the pot base 5.
- a lens 14 to be processed is placed on the membrane part 9 with its convex lens side.
- the lens surface to be machined is slightly concave here.
- the top 15 of the cover part 6 is adapted in the usual way with a slightly larger wheel base to the concave lens surface, so that the schematically indicated polishing cap 16 can process the lens surface unhindered.
- Membrane parts 9 are provided. Preferably, three lenses 14 are processed simultaneously.
- the exemplary embodiment shown in FIG. 2 is based on the same basic construction as in FIG. The same parts are provided with the same reference numerals.
- the cylindrical recess 8 is designed here as a cylinder bore 18 into which a cylindrical holder 19 is inserted, which has the same holding elements for the membrane part 9 as in FIG. 1.
- the holder 19 is provided with a drive shaft 20 which is provided with a bore 13 for fluid communication with the pot space 5 and space 5 extends into the pot.
- the drive axis 20 is held in the bottom of the cylinder bore 18 by a rotary bearing 21, so that the holder 19 is rotatable about its axis 22.
- the drive axle 20 is provided with gear means 23, not shown, which e.g. are coupled to the drive for the spindle shaft 2.
- a convex lens surface is provided for processing here, so that the upper side 15 of the cover part 6 is correspondingly convex.
- the axis 22 is inclined to the axis 17 of the spindle shaft 2.
- the axis 22 would obviously be directed away from the axis 17.
- the different direction of the axes of rotation with respect to the central drive means can be compensated for by appropriately shaped bevel gears 24 as part of the gear means 23, which themselves are not part of the invention.
