Abstract (en)
[origin: ES8308087A1] A device for centering spectacle lenses and for fastening a holding part on the lenses. The device includes a mounting base, a guide or column sleeve arranged vertically thereon, as well as a casing which is rotatable and displaceable in height, and to which a swivel arm which supports the holding part is connected. The object of the present invention is to make it possible, in a simple manner and without great structural expense and without taking a lot of time and effort, to be able to lower the holding part accurately vertically along a prescribed straight line onto the spectacle lens, so that the holding part maintains a desired precise position on the spectacle lens, and with the aid of which the lens can be inserted in an edge grinding machine. To realize this, the device is embodied such that a torque is exerted upon the casing during longitudinal movement relative to the column sleeve. As a result of this torque, a guide edge of the casing is held free of play in sliding engagement against a guide part or pin of the column sleeve.
