【発明の名称】カム軸の回転制御機構付加工機
Document Type and Number:
Japanese Patent JP2794691
Kind Code:
B2
Abstract:
PURPOSE:To make an advance end position of a working tool variable, and also, to make it unnecessary to change a cam one by one even if an object to be worked is changed, by controlling a rotating speed of a cam shaft of a single cam having plural different pressure angle patterns, so as to be variable in one cycle, and moving the tool. CONSTITUTION:A working tool, namely, a roller 2 is fixed to a main shaft base 11 in an advance end position of a rotary forming machine 1 in order to work an object to be worked. The advance end position of the roller 2 can be adjusted by a roller advance end adjusting screw 3 provided on the main shaft base 11, and by a gear box 5 and a pulse motor, the advance end position of the roller 2 is adjusted freely to a set position. The screw 3 receives a pressing force from a cam follower 9 for abutting on a cam 7 and moves the roller 2. A pressure angle pattern of the cam 7 consists of a cam pattern having plural different radiuses of curvature, and by controlling a rotating speed of a cam shaft 8 by a servo-motor 10 so as to be variable in one cycle, it is unnecessary to replace the cam even if the object to be worked is changed.
