DRIVE SHAFT PRESS-FITTING DEVICE

摘要

In a drive shaft press-fitting device, when a collet chuck (clamp) is moved backward by a linear motion means, the end part of the collet chuck closes by collaboration of a tapered surface of the collet chuck and an engagement part of a sleeve, and thereby the collet chuck holds an external thread part of the drive shaft. When the collet chuck is further moved backward by the linear motion means, the drive shaft is drawn out of the axle hub by the collet chuck, and thereby the drive shaft is pressed into the axle hub. After press-fitting, when the collet chuck is moved forward by the linear motion means, the collet chuck opens to be away from the external thread part of the drive shaft by a biasing means.

主权项

1. A drive shaft press-fitting device for pressing a drive shaft having an external thread part at an end into an axle hub, comprising:
a clamp whose end can freely open and close for holding or releasing the end of the drive shaft; a linear motion means for moving the clamp in a direction of drawing out the end of the drive shaft from the axle hub; a tapered surface formed on an outside surface of the end of the clamp, sloping downward in the direction of drawing out the drive shaft; a sleeve placed around the clamp and having an engagement part for moving the clamp to close in sliding contact with the tapered surface of the clamp; and a biasing means placed inside the clamp, for biasing the clamp to open.
