Homework Statement

I have an assembly and I can't seem to figure out what it does.

Homework Equations

The Attempt at a Solution

I know the bottom part simply mounts it to a table or something and its pretty obvious how it would be assembled however I'm not sure if the device as a whole is meant to lift something or hold it in place and I looked online everywhere if someone could help me thanks in advanced. Here is a link to an image of it: http://imgur.com/d4sQXJF

One of the parts is labelled "anvil".
I would suggest that this is exactly what it is: an anvil with a mounting to change the height and orientation.
It neither lifts nor holds in place. It provides part support for something to be worked.

How did you come by the diagram?

What Simon said.

It says "Milling Jack" at the bottom. Has coarse and fine adjustment for height. The V block suggests that the object being supported is probably round (eg a rod or shaft) and perhaps not always the same diameter? The use of friction (set screw 9) for the coarse height adjustment suggests the anvil probably isn't going to be subject to very large vertical forces eg no hammering.

Suppose you wanted to put a flat on a relatively long but small diameter bar/rod in a milling machine. The bar/rod would need to be supported along it's length or it might bend under the pressure of the cutting tool. My guess is that this is intended to provide that support. Might only need one or a whole series placed at intervals.

It is a project I'm doing for my engineering graphics class. Thanks much for the help!
