ズＡを取出し、研磨を完了することができる。With this structure, in order to attach and polish the lens A, the operation handle 31 of the bell clamp mechanism 26 is rotated counterclockwise from the state shown in FIG. Bearing base 1 that meshes with the gear 29 of the
The rack 30 of No. 3 is moved to the left, and the rotary shaft 14 and the work holder 16 at the tip of the rotary shaft 14 which are integrated with the rack 30 are integrated.
Is brought close to the work holder 9 at the tip of the rotary shaft 7 of the lens shaft portion 2, so that the lens A is inserted between the two work holders 9 and 16, and the drive motor 3 is rotationally driven to rotate the rotary shaft 7 and The first belt transmission portion 23, the intermediate shaft 24, and the second belt transmission portion 2 of the interlocking transmission mechanism 22 from the clutch 6.
The large-diameter gear 18 is rotated by rotating the gear 21 via the gear 5, and the large-diameter gear 18 and the gear 19 meshing with the gear 21 are rotated.
And the rotating shaft 14 integrated with the work holder 1 at the tip thereof
Since 6 is rotated, the operation handle 31 is further rotated counterclockwise, and the annular tip 1 of both work holders 9 and 16 is rotated.
Gently press 0 and 17 onto the lens A. As a result, the lens A automatically slides along its spherical surface by the rotation of both work holders 9 and 16, and the optical axis of the lens A can be aligned with the central axis of both rotation shafts 7 and 14. Therefore, the operation handle 31 is moved further in the counterclockwise direction so that the lens A is strongly sandwiched between the work holders 9 and 16, and the stopper 32 that is tilted inward from the state of FIG. The lens A is attached to both work holders 9 and 1 by engaging with the notch 33 formed.
It is firmly clamped and fixed by 6. In this state, either the outer diameter polishing section 34 or the inner diameter polishing section 40 is operated. For example, when the outer diameter polishing section 34 is first operated, the moving table 3
The outer-diameter polishing body 39 at the tip of the polishing shaft 38 on 4 is rotationally driven at high speed, and the moving table 34 moves the outer-diameter polishing body 39 forward, backward, leftward and rightward to control the outer peripheral surface of the lens A while polishing. At that time, since the lens A is firmly sandwiched and fixed by both the work holders 9 and 16, the lens A is highly accurately polished to a predetermined outer diameter without chamfering, and chamfering is performed. The outer diameter polishing body 39 is retracted from the outer peripheral surface of the lens A. Then, when the inner diameter polishing section 40 is operated, the inner diameter polishing body 45 at the tip of the polishing shaft 44 on the moving base 41 is rotationally driven at high speed, and the inner diameter polishing body 45 is operated by the operation of the moving base 41.
Moves forward and is inserted into the center hole B of the lens A through the through hole 15 of the rotary shaft 14 through the work holder 16. Then, the inner diameter polishing body 4 is moved by the movement of the moving table 41 in the front-back and left-right directions.
Reference numeral 5 is pressed against the central hole B of the lens A to polish the inner peripheral surface thereof while being controlled. At this time, since the lens A is firmly sandwiched and fixed by both the work holders 9 and 16, the lens A is highly accurately ground to a predetermined inner diameter without chamfering, and chamfering or the like is performed. Thereafter, the inner diameter polishing body 45 is retracted by the operation of the moving table 41, is withdrawn from the center hole B of the lens A, and is retracted into the work holder 16. When the inner and outer surfaces of the lens A are polished in this manner, the operation handle 31 is raised and the stopper 32 on the inner surface side is removed from the notch step portion 33 of the pedestal 27, and then the operation handle 31 is operated as described above. On the contrary, when it is rotated clockwise, the gear 29 attached to the shaft 28 moves the rack 30 of the bearing base 13 meshing with the gear 29 to the right, so that the rotary shaft 1 incorporated integrally therewith.
4 and the work holder 16 at the tip thereof are separated from the work holder 9 at the tip of the rotary shaft 7 of the lens shaft portion 2, so that the lens A sandwiched between the work holders 9 and 16 should be taken out and polishing should be completed. You can

プ装置。1. A lens shaft portion having a rotary shaft to which a short cylindrical work holder having a sharp tip is attached, and a lens shaft portion having a sharp tip.
And oppositely arranged bell shaft with a rotary shaft fitted with a short cylindrical workpiece holder in the form same size large, with the axially movable by connecting the bell shaft to the bell clamp mechanism part, both Lower
The holder automatically sets the optical axis of the lens around the rotation axis.
As it can be collected by interlocked rotatably the rotating shafts, further outside
Move the diameter polishing body back and forth and left and right to polish the outer peripheral surface of the lens.
The outer diameter polishing part is controlled so that it is arranged on the outer peripheral side of the work holder, while the inner diameter polishing body is mounted on the bell shaft side.
A controllable inner diameter polishing part is installed, and the inner diameter polishing body is placed in the front and rear left
Installed in the through hole of the work holder so that it can move to the right
Seen, the lens grinding machine of the workpiece clamping device, characterized in that polishing the center hole inner surface of the clamped lenses with the inner diameter of the polishing body.
