Definitions
- the invention relates to a polishing head for a polishing machine according to the preamble of patent claim 1.
- a polishing machine for polishing spherical lens surfaces is known from EP 727 280 B1.
- This polishing machine has an upper carriage which can be moved in an x direction.
- a tool spindle which is rotatably mounted about a vertical axis, is connected to this slide.
- the tool spindle is used to hold a dressing tool.
- a workpiece spindle connected to a further slide is provided for receiving the workpiece or the lens.
- the workpiece spindle and the tool spindle with the dressing tool are arranged at a fixed distance from one another. The carriage carrying these two spindles can be moved in the z direction.
- a polishing machine and a method for polishing optical surfaces are known from WO 97/00155.
- the polishing machine has a polishing head which is provided with an elastic membrane.
- the force applied to the surface to be polished is regulated by pressurizing the membrane.
- a disadvantage of this polishing machine is that the size of the surface of the polishing head or the membrane resting on the surface to be polished depends on the pressurization.
- the polishing head with the elastic membrane is biased by an associated spring in the direction of the surface to be polished. Hydraulic cylinders are provided to provide the elastic membrane with tiltability about a point on the axis of rotation in the area of the flexible membrane.
- the application of force to the surface to be polished is detected by assigned sensors, stretch marks and solenoite.
- the polishing of the optical surface is controlled as a function of the rotational speed of the polishing head and the contact pressure acting on the surface to be polished by applying pressure. It is an object of the invention to provide a polishing head for polishing a free-form surface, by means of which a high-quality optical surface can be polished and the use of which ensures constant polishing removal on the entire optical surface to be polished.
- the polishing plate As a result of the measure to connect the polishing plate in a rotationally fixed manner to the drive shaft, it is possible for the polishing plate to rest on the surface to be machined, following the surface contour.
- the articulated connection enables the polishing plate to perform tilting movements so that it lies on the surface to be polished with a maximum polishing surface.
- a piston assigned to the pressure chamber is operatively connected to the drive shaft so that pressurization of the pressure chamber is transmitted to the polishing plate via the drive shaft.
- Figure 1 is a schematic sketch of the polishing head in a section containing the central axis
- FIG. 2 shows a section along the plane FI-II in FIG. 1;
- FIG. 3 shows a section along the plane III-III in FIG. 1;
- Figure 4 section along the plane III - III in an alternative embodiment.
- the polishing head (1) shown in FIG. 1 has a polishing plate (3) with a polishing pad (5).
- the polishing coating (5) rests on a surface (41) of a workpiece (39) to be polished.
- the polishing plate 3 is received on the drive shaft (7) via the articulated connection.
- a spherical socket joint is provided for this non-rotatable articulated connection.
- the drive shaft (7) is provided on the end facing the polishing plate with a spherical imbus head (19) which engages in a recess (13) formed in the polishing plate (3).
- a locking element 15
- a spring element or spring pin on the polishing plate which projects into a recess on the ball socket head, can be provided as the latching element.
- the drive shaft (7) is translationally displaceable via bearing element (23) and is mounted in a hollow cylinder (49) in a rotationally fixed manner.
- the hollow cylinder (49) is driven in rotation by a drive (not shown) of the polishing machine, the rotary movement being completely transmitted to the drive shaft (7) for the polishing head due to the rotationally fixed connection by the bearing element (23).
- a hydraulic or pneumatic system is provided in the hollow cylinder (49) which serves to apply the required polishing pressure to the polishing head. It has a pressure chamber cylinder (31) with a piston (33) which is accommodated in a translationally displaceable manner. To decouple the piston (33) from the rotary movement of the drive shaft (7) and the hollow cylinder, rotary bearings can be arranged between the pressure chamber cylinder (31) and the hollow cylinder (49) and between the connecting rod (32) driven by the piston (33) and the drive shaft (7 ) be provided.
- the pressure chamber (29) formed in the pressure chamber cylinder (31) is assigned a pressure supply (35) with a pressure control valve (37) and a pressure reservoir (36).
- a force directed along a central axis (2) of the polishing head (1) is applied to the piston (33). This force results in a translatory movement of the polishing plate or an increase in the effective polishing force if the polishing layer (5) rests on an optical surface (41) of a workpiece (39) to be polished.
- the rotationally fixed, translationally movable coupling between the hollow cylinder (49) and the drive shaft (7) takes place via a roller bearing (23).
- the drive shaft (7) has a non-rotationally symmetrical outer profile (43), preferably a polygonal profile.
- the positive connection between the outer profile (43) of the drive shaft (7) and the inner wall of the hollow cylinder is achieved via rollers or rollers (25) which are accommodated in the bearing element (23) symmetrically to the outer profile of the drive shaft (7) and on the outer profile ( 43) roll off the drive shaft.
- the axes of rotation of the rollers or rollers are aligned perpendicular to the axis of rotation of the drive shaft (7).
- a ball bearing as shown in FIG. 4, can also be provided.
- the balls (53) are mounted in the longitudinal grooves (51) of the hollow cylinder (49) and further longitudinal grooves (55) of the drive shaft (7) for the rotationally fixed translationally movable connection, the longitudinal grooves extending parallel to the axis of rotation of the drive shaft (7).
- the drive axle has a non-rotationally symmetrical outer profile, in particular a polygonal profile, at least in a region corresponding to the bearing.
- the polishing head whose diameter is smaller than the diameter of the surface to be polished, is moved in a pivoting movement in the radial direction over the optical surface (41) to be polished. Both the workpiece (39) and the polishing plate are driven at almost the same speed in the same direction.
- the polishing plate is moved over the optical surface (41) to be polished, it can be provided that the rotational speed of the polishing plate or the speed of the workpiece is changed, in particular as a function of the radial position of the polishing plate. This change in speed has a positive influence on a constant polishing removal.
- the pressure fluctuations are kept very small, so that the polishing plate rests with constant force on the optical surface to be polished.
- the pressure control valve also helps to compensate for pressure fluctuations.
