Apart from the explanation given above that are spot on, what we should have asked is exactly where the chuck parted from the drill press.
The drill chuck is attached to the Morse adapter via a”Pin” that is also conical, it could have separated here living the Morse Adapter in the Drill Press Quill.
Or the whole Morse adapter – Chuck could have fallen off.

The difference? Your chuck has a metal conical pin sticking on the back.

Here you can see some examples of that:

What you need to do is make sure that there are no nicks or deformations on the conical parts also rust will not allow the surfaces to mate properly, therefore judicios cleaning with a very fine emery cloth and WD40 to remove any traces of rust.

To reassemble a chuck that has come loose you simply put the chuck onto the morse adapter and then make it seat by rapping the assembly (morse adapter down chuck up) onto a non marring surface (a hard wood or aluminun block) a couple times should do it. Hold the assembly by the morse adapter. It is the same as when you re-seat a hammer that has come loose by rapping the handle on a hard surface, the hammer head provides the momentum to re-seat itself.

To seat the morse adapter on the quill you just hold the chuck, rotate the quill until you can see through the key hole, align the morse adapter tail so that it will go into the quill and give it a sharp and fast movement upward if it is correctly seated the chuck will not budge if you pull it…
