BLOCK AND SLEEVE WITH ROTATION-INHIBITING FEATURE |
摘要 |
<p>A block and sleeve assembly is disclosed including a holder block, and a hollow sleeve. In radial cross-section, outer peripheral edges of the shoulder portion of the sleeve have a shape of a first polygon. The holder block and the hollow sleeve include cooperating rotation inhibiting features. For example, the holder block includes a stop projecting forwardly past a plane of the front face and positioned radially offset from a circumference of the opening in the holder block to allow a rearward surface of the shoulder portion of the sleeve to contact the front face of the holder block and to prevent rotation of the hollow sleeve greater than N degrees, N=360/n, where n is the number of sides of the first polygon, by contacting an outer peripheral edge of the shoulder portion with the stop.A sleeve per se and an assembly including a cutting pick are also disclosed.</p> |
