Description

  The present invention relates to a lens drilling apparatus that opens a mounting hole for mounting a frame member such as a bridge or a temple of a rimless frame on a peripheral portion of a spectacle lens that has been ground into a target lens shape.

  In general, when making spectacles having a rimless frame, the peripheral edge of an unprocessed circular spectacle lens is ground into a spectacle lens shape by a lens peripheral processing device to form a spectacle lens, and the peripheral portion of the spectacle lens An attachment hole for screwing a frame member such as a bridge or a temple is formed in.

  Conventionally, there has been known a lens peripheral edge processing apparatus in which a lens drilling apparatus for opening such mounting holes is incorporated (see Patent Documents 1, 2, and 3). In this lens peripheral edge processing apparatus, after the peripheral lens of the spectacle lens is processed into a spectacle lens, a mounting hole can be made in the peripheral edge of the spectacle lens, or a groove for the wire frame can be formed on the peripheral surface of the spectacle lens.

  However, in the conventional drilling apparatus, the drilling means is not pivotally supported so as to be relatively tiltable along the plane formed by the axis of the lens rotation shaft and the drilling means. There wasn't.

  Further, as shown in FIG. 6 of Patent Document 4, the lens holding shaft is inclined in a direction orthogonal to the axis of the drill for drilling, and similarly to the above, along the plane formed by the lens rotation axis and the axis of the drilling means. Since the drilling means was not pivotally supported so as to be relatively tiltable, the drilling of the hole inclined with respect to the edge surface could not be performed.

  Therefore, an object of the present invention is to provide a lens drilling device in which the drilling means is pivotally supported so as to be inclined relative to the spectacle lens.

  In order to solve the above-mentioned problem, the invention of claim 1 is a lens drilling device provided with a punching means for making a hole in a peripheral edge of a spectacle lens attached to a lens rotation shaft. The lens drilling apparatus is supported by a spectacle lens attached to the lens so as to be relatively tiltable.

  In order to solve the above-mentioned problem, the invention according to claim 2 is a lens drilling apparatus provided with a punching means for making a hole in a peripheral edge of the spectacle lens attached to the lens rotation shaft, wherein the punching means faces the spectacle lens. Thus, the lens drilling device is pivotally supported so as to be relatively pivotable.

Therefore, when measuring the tilt of the shadow portion, the brightness is adjusted to tilt the shadow portion. Measure the degree. This inclination data can also be input to the drilling apparatus of the above-described embodiment and used as drilling data.

  As described above, the lens drilling apparatus according to the embodiment of the present invention drills holes (mounting holes) in the periphery of the spectacle lens ML mounted on the lens rotation shaft (Lx, Lx, rotation shaft 28). Means (drilling drill 17) are provided. Moreover, in the lens drilling device, the axis of the drilling means (drilling drill 17) and the spectacle lens ML attached to the lens rotation shaft (Lx, Lx, rotation shaft 28) can be inclined relative to each other. It has come to be supported.

  According to this configuration, it is possible to realize drilling that is inclined with respect to the refractive surface or the edge surface of the spectacle lens ML. Thereby, even if it is a rimless metal fitting etc. which are attached inclining with respect to a refractive surface or an edge surface, drilling can be realized.

  In addition, the lens drilling device according to the embodiment of the present invention includes drilling means (drilling drill 17) for drilling a hole in the peripheral edge of the spectacle lens ML attached to the lens rotation shaft (rotating shaft 28). Moreover, the drilling means (drilling drill 17) is pivotally supported so as to be able to turn relative to the spectacle lens ML.

  According to this configuration, it is possible to realize drilling that is inclined with respect to the refractive surface or the edge surface of the spectacle lens ML. Thereby, even if it is a rimless metal fitting etc. which are attached inclining with respect to a refractive surface or an edge surface, drilling can be realized.

  Furthermore, the hole punching means of the lens drilling apparatus according to the embodiment of the present invention is provided with a V-groove grindstone (bevel grindstone 18) for forming a bevel formed on the periphery of the spectacle lens ML.

According to this configuration, it is possible to realize drilling that is inclined with respect to the refractive surface or the edge surface of the spectacle lens ML, and it is also possible to perform beveling on the edge of the eyeglass lens ML.
