Abstract
A device and a method for polishing of an optical lens by means of rotary tool are proposed, a fixture for the lens being pivotable around a pivoting axis transversely to the axis of rotation by means of a push-rod adjustment and being pivotable up out of a machining position such that the lens can be changed from overhead. This allows a compact structure and easy changing of the lens.
Claims23
A device for machining of an optical lens by means of a tool which can be turned around a turning axis, comprising:
- a motor for rotating the lens, during machining, around an axis of rotation;
- and
- a working space in which the machining of the lens takes place;
- a fixture positioned for holding a blocked lens in the working space and supporting the blocked lens during machining of the lens;
- wherein the fixture is pivotable transversely to the axis of rotation in a vertical plane between a horizontal working orientation and an upward facing, lens changing position in which the lens can be changed from overhead around a pivoting axis running perpendicular to the axis of rotation by means of a push-rod adjustment device.
A device for machining of an optical lens by means of a tool which can be turned around a turning axis, comprising:
- a motor for rotating the lens during machining around an axis of rotation, the axis of rotation running at least essentially horizontally during machining in a machining position;
- a working space in which the machining of the lens takes place;
- a fixture positioned for holding a blocked lens in the working space and supporting the blocked lens during machining of the lens;
- a first drive for linear displacement of the fixture transverse to the turning axis;
- and
- a second drive for pivoting the fixture by means of a push-rod adjustment device,
- wherein the second drive comprises a second slide for linear movement of a push-rod of the push-rod adjustment device, such that the fixture is pivotable in a vertical plane between a horizontal working orientation and an upward facing, lens changing position in which the lens can be changed from overhead around a pivoting axis by linear movement of said push-rod.
A device for machining optical lenses by means of tools which can be turned around turning axes, comprising:
- a working space in which the machining of the lens takes place;
- two fixtures in said working space for simultaneous holding of assigned lenses;
- two motors for simultaneously rotating and machining the assigned lenses held by said fixtures around axes of rotation, the axes of rotation running at least essentially horizontally during machining in a machining position;
- and
- wherein the fixtures together with said motors are pivotable up out of the machining position around a pivoting axis in a vertical plane between a horizontal working orientation and an upward facing, lens changing position in which the lenses can be changed from overhead;
- and
- further comprising a first drive for linear displacement of the fixture transverse to the turning axis and a second drive for pivoting the fixture, wherein the second drive comprises a slide for linear movement of a push-rod of a push-rod adjustment device of the second drive.
