本発明はレンズの研磨等に使用する凹凸球面並
びに平面研磨装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concave-convex spherical surface polishing apparatus and a flat surface polishing apparatus used for polishing lenses and the like.
一般に球面研磨装置は加工物を研磨台に載せ、
この研磨台を回転させつつ、研磨皿が研磨台上を
押圧し、摺動するよう構成されている。従来広く
用いられている装置は、略水平に伸びる揺動杆の

めこの装置ではビビリ等を生じやすく、高い研磨
精度を得ることはできない。 In general, spherical polishing equipment places the workpiece on a polishing table.
The polishing plate is configured to press and slide on the polishing table while rotating the polishing table. The conventionally widely used device presses the polishing plate with a presser bar that extends vertically downward from the tip of a swinging rod that extends approximately horizontally, and slides the polishing plate while moving the presser bar in parallel in a certain direction. This is what I did. For this reason, this device tends to cause chatter and the like, making it impossible to obtain high polishing accuracy.
またこの点を改良した押え棒を常に研磨台の曲

が劣る。 In addition, a device has already been devised that improves this point and has a configuration in which the presser bar always points toward the center of curvature of the polishing table (Japanese Patent Application Laid-Open No. 101697/1983), but it requires adjustment when changing the curvature to be polished. This is complicated, and because the center of curvature is located at a fixed position within the device, its adjustment range is limited to those with a relatively small radius of curvature.Furthermore, it does not use a swinging rod that extends almost horizontally like the device described above. Therefore, when replacing workpieces or inspecting frequently performed during work, it is impossible to flip up the swinging rod to open the polishing table top, which is less practical.
本発明は、従来装置と同様の揺動杆を用いなが

調整範囲が広く、研磨台上の開放操作の可能な研
磨装置を得ることを目的としたものである。 The present invention realizes a configuration in which the presser bar is always directed to the center of curvature of the polishing table while using the same swinging rod as the conventional device, making it easy to adjust when changing the curvature, and having a wide adjustment range. The object of this invention is to obtain a polishing device that can be opened.

角調整が可能となるよう構成したものである。 That is, in the present invention, a swinging rod having a presser bar attached to its tip is swung by the rotation of a swinging rod that is bent and connected to the swinging rod, and the required turning rod is In order to satisfy the condition of locating the center of curvature on the extension of the axis, it is configured so that the mounting angle of the swinging rod can be adjusted by rotating the swinging rod around the connection point between the swinging rod and the turning rod. It is.

る。 Next, the illustrated embodiment will be described. Reference numeral 10 denotes a plate-shaped pedestal, which is fixed to the machine pedestal 12 with bolts 14. By loosening this bolt 14, the pedestal 10 can be rotated around the horizontal axis 16, and its mounting angle can be adjusted. Reference numeral 18 denotes a rotating rod, which is attached to the pedestal 10 via bearings 20, 20', and has a crank 22 at its rear end. Reference numeral 24 denotes a motor, which is attached to the pedestal 10, and a rotary plate 26 is attached to its shaft.
8. Therefore, motor 2
4 causes the rotation rod 18 to reciprocate in both directions around its axis. Reference numeral 30 denotes a swinging rod, which is attached to the tip of the swinging rod 18 with a pin 32 so as to be bendable. This pin 32 is located on the horizontal axis 16. 34 is a presser bar, which moves the swinging rod 3 toward the center point P located on the axis 36 of the rotating rod 18.
It is slidably fitted into the tip of the screw 38 and fixed with a screw 38. 40 is a polishing plate, which is attached to the tip of the presser rod 34 via a universal joint 42. 4
4 is a polishing table on which a workpiece 46 such as a lens is placed. The surface of this polishing table 44 is a spherical surface having a center of curvature at a center point P, is in sliding contact with the polishing plate 40, and is driven by a motor (not shown) so as to pass through the center point P and rotate around a vertical axis. 48 is an air cylinder, and the column 5 attached to the rotating rod 18
0 and the swinging rod 30, and applies a force to press the polishing plate 40 onto the polishing table 44. The attachment position of the support column 50 to the rotation rod 18 can be moved along the rotation rod 18 by loosening the screw 52.

く、精度のよい研磨が実現される。 Since this device has the above configuration, it operates as follows. When the workpiece 46 is placed on the polishing table 44 and the motor 24, the polishing table motor, and the air cylinder 48 are operated, the rotating rod 18 reciprocates, and the swing rod 3
0, the presser bar 34 and the polishing plate 40 rotate around the axis 36 of the rotation rod 18. At this time, the presser bar 34 is always directed toward the center point P, and the polishing plate 40 is pressed against the rotating polishing table 44 by the force of the air cylinder 48. Therefore, no chatter or the like occurs, and highly accurate polishing is achieved.

の曲率中心を向くよう調整される。 When changing the curvature of the workpiece 46, that is, the curvature of the polishing table 44, the center of curvature of the polishing table should be aligned with the rotation rod 18.
The mounting angle of the frame 10 to the machine base 12 may be changed by loosening the bolt 14 so that the frame 10 is positioned on the axis 36 of the frame 12.
At this time, the screw 52 is loosened and the position of the support column 50 is changed as necessary so that the air cylinder 48 functions properly. In this way, the presser bar 34 is always on the polishing table 44.
is adjusted to face the center of curvature.
なお、研磨台４４の曲率中心は第２図に示すよ
うに、研磨台４４下方に位置するばかりでなく、
第３図に示すように研磨台４４上方に位置するよ
うにすることもできる。 Note that the center of curvature of the polishing table 44 is not only located below the polishing table 44, as shown in FIG.
It can also be positioned above the polishing table 44 as shown in FIG.

い。 In addition, when the curvature of the polishing table 44 is changed, the polishing table 44
The center of curvature P may be positioned on the axis 36 of the rotation rod 18 by changing the height of the rotation rod 18 . In this case, it is necessary to loosen the screw 38 and adjust the length of the presser bar 34 protruding from the swinging rod 30 so that the presser bar 34 extends toward the center of curvature P.

い。 As described above, according to the apparatus of the present invention, since the presser bar always faces the center of curvature of the polishing table, highly accurate polishing can be performed. In addition, when changing the curvature of the workpiece, that is, the polishing table, readjustment is easy, and the center of curvature can be freely set even outside the device, so the range of curvature that can be polished is extremely wide. In particular, polishing can be performed not only when the polishing table is convex but also when it is concave. In particular, if the rotating rod is made vertical, it is possible to polish surfaces with infinite curvature, that is, flat surfaces. Furthermore, since there is a swinging rod that extends approximately horizontally, the swinging rod can be flipped up to open the polishing table top, providing good operability when replacing or inspecting workpieces.
