Patent ID: 8620598

Claim:
A bushing press-fitting inspection device used in a bushing press-fitting apparatus that, using a press-fitting mechanism, supports a bushing at an end of the bushing press-fitting apparatus and that press-fits, over a certain stroke at a certain load, the bushing into a bushing press-fitting portion formed in part of a structure in a cylindrical shape that is included in a workpiece, the bushing press-fitting inspection device comprising: setting means for setting a start point lower limit load and a start point upper limit load, which are represented by a relationship between a stroke and a load at the beginning of press-fitting of the bushing that is to be press-fitted using the press-fitting mechanism, and an end point lower limit load and an end point upper limit load, which are represented by a relationship between a stroke and a load at the end of press-fitting of the bushing, as press-fitting conditions; storage means for storing the press-fitting conditions set by the setting means; input means for, after the press-fitting mechanism begins to operate, inputting an actually measured stroke and an actually measured load corresponding to the actually measured stroke that have been detected by detection means provided in the press-fitting mechanism; judgment means for judging, by performing a comparison, whether or not the actually measured load that corresponds to the actually measured stroke and that has been input by the input means is within a region of the press-fitting conditions; and output means for, when a result of the judgment made by the judgment means is that the actually measured load is outside the region of the press-fitting conditions, outputting an indication signal to indication means provided in the press-fitting mechanism after receiving an unsatisfactory-result signal from the judgment means, and, when the result of the judgment made by the judgment means is that the actually measured load is within the region of the press-fitting conditions, outputting an indication signal to the indication means provided in the press-fitting mechanism after receiving a satisfactory-result signal from the judgment means.
