BLADE WIDTH ADJUSTING MECHANISM FOR WOOD WORKING ROTARY DOUBLE BLADE AND CUTTING BLADE ROTARY SHAFT WITH DETACHMENT MECHANISM

摘要

PURPOSE: To make is possible to adjust arbitrarily blade widths of two sheets of cutting blades without preparing a spacer and at the time of exchange of the blades, detachment can be performed simply, by a method wherein the title rotary shaft is constituted pf a taper shank type rotary blade holder provided with a pull stud and a cutting blade rotary shaft possessing a pull stud pulling shaft at the shaft center. ;CONSTITUTION: A rotary cutting blade 1 is connected with a movable blade holder 38 and a rotary cutting blade 2 is connected with a stationary blase holder 40. A movable holder 38 is connected with a spline shaft 34 by a spline nut 37 and bolt 35 and the stationary blade holder 40 is connected with a spline nut 39. On the one hand, a pull stud 4 is fitted to the stationary blade holder 40 turnably and a screw part 33 is screwed on to a female screw part provided on the shaft center of the spline shaft 34. Therefore, when the pull stud 4 is turned, the spline shaft 36 and spline nut 37 are slid each other, a movable blade holder 38 is moved laterally and widths of the rotary blades 1, 2 are changed.;COPYRIGHT: (C)1995,JPO
