Problems solved by technology

[0006] However, in the production of small batches and many varieties, frequent cam exchange is necessary, so the preparation time is wasted, and the operating efficiency of the processing equipment is greatly reduced.
In addition, in order to process various shapes of curved surfaces, it is necessary to prepare reference cams that match each shape, which increases manufacturing costs.

other Embodiment approach

[0083] In the above-described embodiment, one X-axis motor 31 and two Y-axis motors 32 and 33 for independently moving the first and second Y-axis plates 16 and 18 are provided. Conversely, two X-axis motors for independently moving the first and second X-axis plates 13 and 14 and one Y-axis motor for moving one of the first and second Y-axis plates 16 and 18 may be arranged.

[0084] In the above-described embodiments, the present invention is applied to a lens spherical surface processing device. The present invention is also applicable to lens processing devices for processing curved surfaces other than spherical surfaces. For example, the conical surface processing of the lens material W can be performed by moving the processing tool along the conical surface. In addition, it is also possible to perform aspherical processing in the same way as the waveform generator.

Abstract

The invention realizes a lens grinding device which is adapted to small-lot, various processing without a cam mechanism. A sphere grinding device (1) includes: a first, a second X shaft plates (13), (14); a first, a second Y shaft plates (16), (18) provided on the first, the second X shaft plates; a connection plate (19) connecting the first and the second Y shaft plates (16), (18) and provided with a tool shaft (6) for mounting a grinding tool (5). The second X shaft plate (14), the first and the second Y shaft plates (16), (18) are movable using a X shaft motor (31), Y shaft motors (32, 33), such that the grinding tool (5) is swung along a prescribed swinging track. The grinding tool (5) can be swung without the cam mechanism, and the swinging track of the grinding tool (5) can be simply varied via a NC control disc (50) without component exchange.

Description

technical field [0001] The present invention relates to a lens processing device that performs predetermined motions such as swing motions while pressing a processing tool such as a grinding tool against a lens material to be processed to perform spherical surface processing or the like. Background technique [0002] In a lens processing device, for example, a lens grinding device that processes a curved surface of a lens, a grinding tool is rocked relative to a lens material to be processed by a cam mechanism. Patent Document 1 discloses a spherical surface grinding device using a cam mechanism. [0003] The grinding device disclosed here comprises: a reference cam having a cylindrical curved surface; two cam push rods moving along the cylindrical curved surface of the reference cam, a swinging body supported by the cam push rods; grinding dish. Use the driving device to move the cam push rod on one driving side along the cam surface, and make the other cam push rod follo...
