Abstract:
Apparatus for supporting a coaxial cable, or the like, and effecting cutting and stripping operations to remove a portion of one or more layers which concentrically cover a central conductor. A single blade, having a circular cutting edge, is moved in an orbital path about the cable with rotary motion of a motor translated to orbital motion of the blade through a plurality of plates relatively movable on crossed, linear, roller bearings and a shaft eccentrically affixed to the motor with the shaft and motor axes at an acute angle to one another. The shaft extends through a spherical bearing mounted in one of the plates, thereby translating nutational motion of the shaft to orbiting motion of the plate which is directly attached to the blade. A unique clamping assembly includes a pair of jaws having respective gear racks engaging a single pinion gear on a motor output shaft for linear movement of the jaws by equal distances in opposite directions. A microprocessor controls the level of current to the motor, thereby adjusting the clamping force applied to the cable, and increases this force during the stripping operation, when maximum axial force is applied to the cable.
