Abstract
A workpiece holder, particularly adapted for holding eyeglasses lenses (L), comprises a support (12) on which there are arranged two clamps (14, 17, 117) for clamping each a portion of a lense. Each clamp defines an axis (A) which is substantially perpendicular to the portion of lense clamped thereby. Each clamp is positionable and lockable with said axis (A) oriented in any direction at the interior of an ideal cone (A1 - A2) having a vertex through which the said axis (A) is passing. Positioning means (3, 4, 40) are provided for displacing the said support (12) along a horizontal plane with respect to a fixed tool (28).
Claims12
A holder for holding the two lenses (L) of a pair of rimless eyeglasses for their machining by at least one fixed machining tool (28) to obtain the suitable mounting points for the side bars and nose bridge, comprising a pair of clamps (14, 17, 117) each of which is intended for holding one lens, said two clamps being mounted on a common support (12), means (3, 4, 40) being provided for displacing the said support (12) along a horizontal plane with respect to the fixed tool (28), each clamp (14, 17, 117) being designed for clamping a portion of a lens (L), and defining an axis (A) which is substantially perpendicular to the portion of lens clamped thereby, said clamp being positionable and lockable with said axis (A) oriented in any direction at the interior of an ideal cone (A1-A2) having a vertex through which the said axis (A) is passing.
