METHOD FOR INSTALLING STEPPED SHAFT IN MECHANIZED MACHINE TOOL Russian patent published in 2024 - IPC B23Q3/06 

FIELD: metal processing.

SUBSTANCE: used for installing stepped shafts in a mechanized machine tool, which has two clamping mechanisms with jaws, one of which is self-centering. The installation method includes placing a shaft in a device, simultaneously moving the jaws of the clamping mechanisms closer to this shaft, centering the shaft in a self-centering mechanism by touching its jaws with the shaft, interrupting the movement of the jaws of the clamping mechanisms, followed by resuming the interrupted movements of the jaws, and securing the shaft simultaneously with all the jaws of the mentioned mechanisms. In this case, a mechanized device is used that has a cradle with a ledge, and the second clamping mechanism of which is made non-self-centering with the possibility of variable movement of the jaws, while the shaft is placed on the cradle, placing the shaft with the base surface between the jaws of the self-centering mechanism and pressing it in the axial direction to the ledge of the cradle, and after centering the shaft in a self-centering mechanism, the movements of only the jaws of this mechanism are interrupted, continuing the movement of the jaws of the non-self-centering mechanism, and after touching the shaft with one of the jaws of the non-self-centering mechanism, its movement is interrupted, continuing the movement of its second jaw, and after touching the shaft with the second jaw of the non-self-centering mechanism, the interrupted movements of the jaws are resumed before fixing the shaft in this device.

EFFECT: increasing the accuracy of shaft installation when processing it on a machine.
