2, control oscillating cylinder 29 action, drive camshaft 36 90-degree rotation, make that middle clamper 25 is closed, upper clamper 22 is opened, bearing inner race falls successively, and nethermost bearing inner race is clamped by middle clamper 25; Meanwhile, control lifting cylinder 41 action, make the lower gripper 51 closed rise to a high position.
3, oscillating cylinder 29 action is controlled, drive camshaft 36 reposition, under the effect of back-moving spring 35, upper clamper 22 is closed, middle clamper 25 is opened, because the spacing of upper clamper 22 and middle clamper 25 equals bearing inner race width, bearing inner race second from the bottom is clamped by upper clamper 22, and nethermost bearing inner race fall into lower gripper 51.
4, control lifting cylinder 41 action, make lower gripper 51 be down to low level, i.e. the installation site of bearing inner race; Control oscillating cylinder 44 action, drive open and close device 48 90-degree rotation by rotating shaft 46, lower gripper 51 is opened, and bearing inner race is in place.
5, control lifting cylinder 41 action, make lower gripper 51 rise to a high position; Control oscillating cylinder 44 action, drive open and close device 48 reposition by rotating shaft 46, lower gripper 51 is closed.
6, again perform the 2nd step, start new round circulation.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
