仕上げる必要があり、その加工が非常に困難であった。Structure of a conventional example and its problems A conventional example of a polishing apparatus for obtaining a convex spherical surface using glass or the like is shown in FIG. 1, and a side cross section thereof is shown in FIG. Conventionally, with a convex spherical surface, a plurality of workpiece holders 3 are provided on the main surface of a spherical substrate 1, a workpiece 4 is attached to the workpiece holders 3, and the surface of the polishing pitch or polishing pad 7 is set to the desired workpiece. A polisher 5 attached to the surface with a radius of curvature of This was obtained by rotating the polishing plate rotating shaft 6 in the direction of arrow 9 and swinging the polisher 6 in the direction of arrow 10. However, in this polishing device, it was necessary to finish the inner wall of the polishing dish into a spherical surface, which was extremely difficult to process.

つきが生じやすいという欠点があった。It is necessary to fix the workpieces to the workpiece holder so that the normal direction of each workpiece coincides with the radial direction of the spherical surface of the inner wall of the grinder. Since the workpieces are fixed to a spherical substrate, the normal directions of the workpieces do not coincide with each other, and therefore there is a drawback that variations tend to occur in the direction in which the workpieces are fixed to the substrate.

工物保持体１５に伝達され、被加工物１４は保持体回転
軸１８を軸として回転運動する。The cylindrical body 11 is placed on a rotating roller 29, and as the rotating roller 29 rotates in the direction of arrow 12, the cylindrical body 11 rotates in the direction of arrow 13. The workpiece 14 is attached to the workpiece holder 15id, and the holder rotation axis 1
8 sandwiching the base plate 16 and connected to a rotary plate 17, and the rotary plate 17 is provided with a crank receiver 19 at a position at a radius r from its center. A crank arm 20 having holes at positions equal to the center spacing of the workpiece holder 15 is attached to the crank receiver 19, and is connected to the drive unit 21 via an arm 22 having an effective length r. . As a result, the rotational movement of the drive unit 21 in the direction of arrow 23 is transmitted to each workpiece holder 15, and the workpiece 14 rotates about the holder rotation axis 18.
また、被加工物保持体１５が設けられている基板１６は
、変心カム２４の矢印２７の方向の回転運動がばね２５
と連結棒２６によって矢印２８方向の往復運動に変換さ
れるため、円筒体１１の軸方向に直線往復運動する。Further, the substrate 16 on which the workpiece holder 15 is provided is such that the rotational movement of the eccentric cam 24 in the direction of the arrow 27 is prevented by the spring 25.
This is converted into a reciprocating motion in the direction of the arrow 28 by the connecting rod 26, resulting in a linear reciprocating motion in the axial direction of the cylindrical body 11.

保持体１５を設けた基板１６の１直線往復運動当たりの
円筒体１１０回転数は、円筒体内壁を一様に使って加工
することから、整数倍にならないことが望ましい。The workpiece 14 is pressed against the inner wall of the cylinder 11 supplied with free abrasive grains due to the rotational movement of the cylindrical body 11 and the workpiece holder 15 and the reciprocating movement of the substrate 16 of the workpiece holder. The cylindrical body 11 is processed and polished into a convex spherical surface having a radius of curvature equal to the radius of the inner wall of the cylindrical body 11 . Note that the number of revolutions of the cylindrical body 110 per linear reciprocating motion of the substrate 16 provided with the workpiece holder 15 is preferably not an integral multiple since the cylindrical inner wall is uniformly used for processing.
なお、上述の実施例においては型磨材として遊離砥粒を
用いたが、円筒体内壁に砥粒を貼り付けても同様の効果
が得られる。In the above embodiment, free abrasive grains were used as the mold polishing material, but the same effect can be obtained even if the abrasive grains are attached to the inner wall of the cylindrical body.

のそろった凸球面加工物か得られる。Effects of the Invention As described above, the spherical polishing apparatus according to the present invention processes a workpiece by pressing it against a cylindrical body, and does not use a conventional spherical polishing plate. Since the cylindrical body can be easily obtained with high precision by lathe processing, it is possible to easily obtain a convex spherical surface with higher precision than with conventional polishing equipment. Furthermore, since the workpieces are aligned and fixed in a straight line, the normal directions of the workpieces are parallel, which has the advantage of increasing the accuracy of attachment to the holding part. Since the workpiece is rotated by a crank mechanism, there is less vibration applied to the workpiece.
Furthermore, the rotational force transmitted to each workpiece is equalized, and convex spherical workpieces with uniform precision can be obtained.
