DEVICE FOR SUPPORTING DETECTION END AND FOR DRIVING IN DETECTION END COPYING DEVICE OF METALLIC SURFACE

摘要

PURPOSE:To realize a small-size structure of the device to be installed into a narrow space, by sticking an electric coil assembly for detection of a distance on the metal surface at an end of a flexible pantograph. CONSTITUTION:A pantograph 1 is constituted with the stainless arms 1a11-1a61 plus 1a21-1a62 and the shaft pins 1b11-1b81 plus 1b12-1b62. The pins 1b11 and 1b12 at the highest part of the pantograph 1 are attached to the base 2; while the pins 1b71, 1b72, 1b81 and 1b82 at the lowest part are attached to an electric coil assembly 3, respectively. When the motor 9 turns, the wires 41 and 42 are pushed out to expand the pantograph 1. Thus the assembly 3 is shifted.
