Discussion Overview

The discussion revolves around identifying the function of a mechanical assembly, specifically whether it is designed to lift or hold an object in place. Participants analyze the components and their labels to deduce the assembly's purpose, with a focus on its application in engineering contexts.

Discussion Character

  • Homework-related, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant notes that the assembly mounts to a table and questions whether it is meant to lift or hold something.
  • Another participant identifies a labeled part as an "anvil" and suggests that it provides support rather than lifting or holding in place.
  • A third participant mentions the label "Milling Jack" and discusses its height adjustment features, proposing that it supports round objects like rods or shafts during milling operations.
  • This participant also speculates on the assembly's use in preventing bending of long, small diameter bars under cutting pressure.
  • A later reply clarifies that the inquiry is part of a project for an engineering graphics class.

Areas of Agreement / Disagreement

Participants generally agree that the assembly is not intended to lift but rather to support objects, though there are varying interpretations of its specific application and functionality.

Contextual Notes

Participants rely on the labeling of parts and their own interpretations, which may depend on specific definitions or assumptions about the assembly's intended use.

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

 
Physics news on Phys.org
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!
