Abstract
A device for connecting a cooling nozzle to a cooling lubricant supply for a grinding machine includes a central axis, a housing arranged for receiving the cooling nozzle, a rotary-linear transmission and a tube section. The rotary-linear transmission has a drive element, pivotable about the central axis, and a manual lever fixed to the drive element. The tube section is rotationally fixed in the housing and movable along the central axis by the rotary-linear transmission to be pressed against the cooling nozzle. The rotary-linear transmission may be a self-locking transmission. The drive element may have a thread structure which extends over less than a full revolution.
Claims12
A device for connecting a cooling nozzle to a cooling lubricant supply for a grinding machine, comprising
- a housing;
- a rotary-linear transmission that comprises a drive element which can pivot about a central axis and which is connected to a manual lever;
- a tube section as an output element that can be moved along the central axis and is secured against rotation in the housing;
- and
- a pair of guide jaws:
- formed by the housing;
- extending exclusively orthogonal to the central axis;
- and
- arranged to engage the cooling nozzle to restrict displacement of the cooling nozzle to be exclusively orthogonal to the central axis, wherein the tube section can be pressed against the cooling nozzle by means of the rotary linear transmission.
A device for connecting a cooling nozzle to a cooling lubricant supply for a grinding machine, comprising
- a central axis;
- a housing arranged for receiving the cooling nozzle, the housing comprising a rectangular housing base;
- a rotary-linear transmission comprising:
- a drive element, pivotable about the central axis;
- and
- a manual lever fixed to the drive element;
- a tube section, rotationally fixed in the housing and movable along the central axis by the rotary-linear transmission to be pressed against the cooling nozzle;
- and
- two L-shaped guide jaws:
- fixed to the housing base;
- extending orthogonal to the central axis;
- and
- arranged to receive the cooling nozzle therebetween to restrict axial displacement of the cooling nozzle away from the tube section.
