Abstract

PURPOSE: To prevent heat distortion through a high/low speed change by building up a gear shifter with a rack, a control cam at the ram tip and a limit switch in an automatic spindle speed transmission device of a ram type milling machine.
CONSTITUTION: A milling tool is rotated and driven by a DC motor DM whose power is transmitted to bevel gears 30 and 31 through a gear device. The spindle is slid with a gear shifter 25 and a rack 34 to change the rotation speed thereof to the low or high range. The rack 34 is moved by a linear operation mechanism RH composed of a small motor. A controlling cam 40 is provided at the tip of the rack 34 while limit switches S1, S2, S3 and S4 are arranged about the controlling cam. The position of the gear shifter 25 is detected and controlled to set the transmission freely.
