Abstract
PURPOSE: To make checking of the operation of a trail stock in a lathe automatically by the use of the moving distance of trail stock by measuring automatically the moving distance of the center of trail stock.
CONSTITUTION: The trail stock 7 is placed on a fixed position and a sleeve 6 equipped with a center 5 is driven by a drive device 8 in the direction of arrow to allow the measuring instrument 9 to measure the amount of this sleeve's 6 movement. If the length of an object 4 provided with a center hole 10 and chucked by a pawl 3 is expressed by AC, the depth of the center hole 10 by BC, and the starting point of the center 5 by D, fitting of the center 5 in the hole 7 can be judged by whether the actual moving distance of the center 5 satisfies a relation such that AD-ACL≤AD-AC+BC. As AD and BC are constant while AC is merely variable, the moving amount of the center 5 is determined by AD-AC+BC. Thus the relation of the center 5 with the center hole 10 can be checked.
