Title: Spindle head position regulator for neumerical control router and the like
Inventor: TANAKA TAKESHI
IPC: B27C9/04
Filed: 1989-12-18
Abstract: PURPOSE:To make a special feeding means and the like unnecessary, simplify the constitution of the title device and retain highly accurate vertical accuracy by a method wherein a roll bearing is employed in the spindle head regulating device to effect the movement of the spindle head by hand smoothly and lightly. CONSTITUTION:When distances between spindles are set based on the reference of a spindle head A, second from left, the engaging pin 24 of the spindle head A at the most left side is removed out of a recess 22a, the spindle head A is moved leftward and the approximate distance between the reference spindle head A is measured while the movement is stopped when the value of the distance has arrived at a desired set value substantially. The engaging pin 24 is engaged with the recess 22a at this position. The above-mentioned moving and regulating operation of the spindle head is effected with respect to the other two heads A in the same amnner. The moving operation of the spindle head A is effected horizontally by the rolling effect of a direct guide bearing with respect to a direct guide and, therefore, the pindle may be set at a predetermined position smoothly and quickly by a light operating force. On the other hand, a clearance between rolling surfaces is small in a rolling system direct moving guide bearing and, therefore, a direct accuracy is maintained in a high accuracy at all times.
