本発明は眼鏡レンズの外形形状と眼鏡フレーム
枠との形状とを正確に合致させる為フレーム枠の
内周長を測定する眼鏡フレーム枠V状溝内周長測
定装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eyeglass frame frame V-shaped groove inner circumference length measuring device for measuring the inner circumference length of a frame frame in order to accurately match the outer shape of an eyeglass lens with the shape of an eyeglass frame frame. .
眼鏡レンズをフレーム枠に嵌込む作業の一つと
して眼鏡レンズの外周を枠合せの為に研削する作
業がある。 One of the operations for fitting eyeglass lenses into a frame is grinding the outer periphery of the eyeglass lenses in order to fit the frame.

えられた眼鏡レンズは枠より少し大きめに加工
し、フレーム枠に合せて眼鏡レンズを研削して枠
フレームに嵌込むことが行われる。 Spectacle lenses are shaped by following a template that fits the frame from the required original lens. Due to processing errors and other reasons, the frame frame is different for each product, and even for the same product, the left and right sides are different, and the lens shape cannot be uniformly determined. For this reason, the eyeglass lens prepared using the copy mold is processed to be slightly larger than the frame, and the eyeglass lens is ground to fit the frame and then fitted into the frame.

加工不良が生ずる虞れもある。 Conventionally, the grinding process for frame matching involves repeating the grinding process and the process of actually fitting the frame into the frame, in order to finally match the shape of the eyeglass lens with the frame. The glasses are machined while attaching and detaching the spectacle lenses, or are processed using a handrail. Therefore, it takes a lot of time and there is a possibility that processing defects may occur.

る。 In view of such circumstances, the present invention provides a measuring device capable of measuring the inner circumferential length of a V-shaped groove that fits with the circumferential edge of a spectacle lens in a frame, and processes the spectacle lens using a processing machine based on the measured inner circumferential length. The purpose of this invention is to dramatically improve the efficiency of frame fitting work by making it possible to immediately grind to the final shape without removing the frame, and also to greatly improve the accuracy of the grinding process.

従させる。 As shown in the figure, the eyeglass frame 22 is loaded and the rotor 17 is fitted into the V-shaped groove 24. The contact pressure between the rotor 17 and the V-shaped groove 24 is applied by the bar spring 18, and in this state, the motor 6 moves the turntable 3.
Rotate. Due to the biasing force of the bar spring 18 and the sliding mechanism of the slide frame 12, the rotor 17 rotates while rolling along the V-shaped groove 24. When the turntable 3 rotates once, the cam 25 activates the micro switch 20 to stop the motor 6. Therefore, the rotor 17 has rolled by the entire inner circumference of the frame 23, and multiplying the circumference of the rotor 17 by the number of revolutions detected by the encoder 15 gives the inner circumference of the frame 23. Can be measured. Also, since eyeglass lenses are not perfectly circular, their peripheral edges are 3
The V-shaped groove 24 also moves up and down. For this vertical displacement, the parallel link 14,
The rotor 17 is caused to follow the action of the balance spring 19.

ム枠の形状に正確に合わせることができる。 Since the outer shape of the eyeglass lens is similar to the shape of the frame when it is ground from the original lens, the eyeglass lens is adjusted so that the outer circumference of the eyeglass lens matches the inner circumference measured above. By cutting, the lens can be accurately matched to the shape of the frame without removing it from the processing machine.
