Abstract
The invention relates to a novel insulation stripping head which can also be used in particular as a spare part for existing rotational insulation stripping apparatuses. It is particularly stable and simple to produce while at the same time providing the same or improved precision. It substantially has insulation stripping blades (3) and centering jaws (4) which can be swiveled in laterally and, during operation for insulation stripping, rotate together about the main axis (1).
Claims32
An insulation stripping head comprising:
- a rotary retaining body configured to rotate around a main axis;
- said retaining body having a distal end;
- said retaining body having a proximal end;
- a plurality of passages in said retaining body, each said passage passing from said proximal end to said distal end;
- a plurality of coaxial drive shaft assemblies, each one respectively passing through a respective one of said plurality of passages in said retaining body, and each radially spaced from the main axis;
- said plurality of coaxial drive shaft assemblies each including a respective hollow drive shaft;
- said plurality of coaxial drive shaft assemblies each including a respective inner drive shaft configured to pass through said respective hollow drive shaft;
- said retaining body connected to a rotary main shaft configured to rotate on the main axis and thus orbit said plurality of coaxial drive shaft assemblies around the main axis;
- a respective hollow drive shaft cam on each of said hollow drive shafts;
- a respective inner drive shaft cam on each of said inner drive shafts;
- on said main shaft, a first longitudinally displaceable control mechanism configured to actuate said hollow drive shaft cams;
- and,
- on said main shaft, a second longitudinally displaceable control mechanism configured to actuate said inner drive shaft cams.
