ABSTRACT:
A method and an apparatus for press fitting characterized in permitting the simultaneous measurement of a press fitting body with the press fitting, and characterized in improving the accuracy of the press fitting. The method comprises the steps of: temporarily press fitting a press fitting body (8) from the top of a press fitted part of a press fitted member (20), located at a prespecified height with respect to the press fitted part, such that a ball screw shaft of a ball screw is moved downward by means of a servo motor and, consequently, the body (8) is press fitted to the press fitted part at a prespecified length; executing a zero adjustment of a linear gauge and a load cell, wherein the linear gauge is composed such that a measuring member (36) is in contact with a top end of a measured member (30) which moves together with the body (8), and the load cell is composed so as to measure a press fitting force of the body (8); constant size press fitting executed to the member (20) of the body ( 8) at a prespecified length; differential press fitting, executed in the case where the measured results, the measured results of the linear gauge and the load cell at the time when the constant size press fitting process is terminated, are in prespecified ranges, and wherein the body (8) is press fitted to the member (20) according to the difference between the results and an objective length; and determining, whether or not the press fitted length, set by the differential press fitting step, is equal to the specified press fitting length.
