KNOCKOUT DEVICE WITH POSITIONING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a knockout device with a positioning function which has a structure endurable enough to stand the rotational inertia of a main spindle so as to be applicable to the main spindle rotating like a lathe and which is formed with a positioning surface for fixing a work in the rotation-axis direction of the main spindle. SOLUTION: This knockout device is provided with a knockout plate 1 vertically moving a work 3 so as to be knocked out, and a housing 2 which has a function of receiving the work 3 and positioning it on the top surface thereof and a storing part for the knockout plate 1 capable of performing storing operation so that the top surface may be flush with the top surface of the knockout plate 1. The housing 2 is fixed on the chuck body 9 of an air chuck 8, and the air chuck body 9 is fixed on a main spindle 15.
