Abstract
A subassembly with a supporting element for a machine bed of a lathe, and of a machining unit which is arranged on the supporting element and has a machining axis, wherein a solid-body joint, via which the machining unit is arranged in a movable manner on the supporting element, is provided. A lathe for plastics spectacle lenses, having a machine bed, having a tool mount or workpiece mount which is arranged at least indirectly on the machine bed, and having a subassembly which is arranged at least indirectly on the machine bed, wherein the workpiece and the tool can be oriented in relation to one another via the solid-body joint.
Claims19
A subassembly, consisting of:
- a supporting element of a machine bed of a lathe for plastic spectacle lenses and a machining unit arranged on the supporting element for the machining of the spectacle lenses, wherein a solid-body joint is provided, by which the machining unit is pivotably arranged on the supporting element, wherein the solid-body joint has an axis of articulation and a pivot axis R and serves for orienting of a relative position between the machining unit and the supporting element, and wherein the machining unit is arranged between the solid-body joint and the actuator in regard to the direction of the pivot axis R and can move by the actuator in a direction perpendicular to the pivot axis R.
A subassembly, consisting of:
- a supporting element of a machine bed of a lathe for plastic spectacle lenses and a machining unit arranged on the supporting element for the machining of the spectacle lenses, wherein a solid-body joint is provided, by which the machining unit is arranged and can pivot on the supporting element, wherein the machining unit has a machining axis, while the solid-body joint has several fastening elements and at least one bending element that is fixed via the fastening elements, and the bending element has two area moments of inertia M1, M2, of which the respective vector V1, V2 that maps the area moments of inertia M1, M2 is situated perpendicular to the machining axis.
A subassembly, consisting of:
- a supporting element of a machine bed of a lathe for plastic spectacle lenses and a machining unit arranged on the supporting element for the machining of the spectacle lenses, wherein a solid-body joint is provided, by which the machining unit is arranged and can pivot on the supporting element, wherein the machining unit is coupled to an actuator, by which movement about the solid-body joint is possible, and wherein the actuator has a step motor with a motor shaft and a transmission spindle coupled to the motor shaft in nonrotatable manner.
