$($Can someone explain to me whats being asked here, like what am i supposed to do in this assignment$)$

Open the following part K:DRWG$2220\backslash$A$6\_$Project Backing Plate.SLDPRT$.$

Examine the part carefully.

For this part create the following:

$1.$ A fixture to check the two features as designated in red.

$2.$ A weldment stand for your checking fixture so that the bottom of the fixture is $30$ inches off the ground.

$1$

Part $1-$ The Checking Fixture $(75\%)$

This fixture MUST be created as a TOP DOWN design, using the "Hole Series" and standard

inch sizes whenever possible. It will check the distances of the features shown in red. Refer to

the "Mouse Checking Fixture" $($also found on the scratch drive as a Solid Works Epart file$)$ as a

sample checking fixture. Feel free to use $3$D Content Central for standard parts. Minus $20$ if the

fixture is not complete.

The following features must be present in your checking fixture:

$2$ gauges to check the two feature sizes

A way to "fool proof" the fixture so the part can only go in one way

A way to raise and lower the part or the gauges so the features can be checked

All nonstandard parts must be able to be machined using standard milling and turning

techniques.

Part $2-$ The Weldment $(25\%)$

The weldment is a stand for your checking fixture and must include the following features:

The bottom of your checking fixture must be $30^(\text{'}\text{'})$ off of the floor

The checking fixture must not be able to be pushed off of the weldment $($I$.$E$.$ it must be

lifted in and out of the weldment$)$

There must be a foot on each leg with a means to allow the stand to be leveled

It must have a spot for at least one supported shelf in the legs $12"$ off of the floor

All horizontal members must have a gusset supporting them

No marks will be given if this is not created as a weldment

A weldment drawing must be created on a B size sheet$($s$).$

A final assembly must be created with the fixture and the stand.

Part $1$ Feature Possible Marks Actual Mark All sketches are fully defined. All parts created by the student can be machined using standard milling and turning techniques. $20$ Two gauges are employed. They can easily be read by the user. The gauges are held securely in the fixture in a manner that will not impede their function. $10$

Part can only be placed on the fixture in the correct position $($I$.$E$.$ the fixture is fool proof$)$ There are no redundant locators.

$5$ The part or the gauges easily move to make contact with each other, allowing for accurate and repeatable part measurement. $10$ All assemblies are configured for both the exploded and collapsed states. $10$

Assembly is constrained so that the checking fixture can only move as the actual one would. All sub$-$assemblies are flexible $($there must be at least one sub$-$assembly$)$

$15$ Standard inch sizes are used where appropriate and the fixture can be leveled. $5$

Bonus The dial on the indicator moves accurately with the plunger.

Bonus $5$

$3$

Part $2$ Feature Possible Marks Actual Mark The bottom of the checking fixture will be $30"(+//-1//16^(\text{'}\text{'}))$ off of the floor. $3$ The checking fixture cannot be accidentally pushed off of the stand $2$ The feet allow for leveling of the part. $3$ The shelf is $12^(\text{'}\text{'})(+//-1//16^(\text{'}\text{'}))$ off of the floor $2$ All horizontal members have a gusset or sit on top of another structural member. $5$ All joints have the appropriate welding symbol as required by your instructor. $5$

All sketches are fully defined. The stand does not interfere with the checking fixture.

$2$

Orthographic projections are printed on an appropriate size paper, include the Cut List with the columns as required by your instructor, and each item has a balloon attached, welding symbols are included Enough views are included so that the weldment can be made from the print.

$3$

$4$

Additional Marks will be deducted for the following $(-5$ for each item$)$:

Drawings not folded correctly

Your name, part name, material and mass properties not appearing in the drawing

template as a linked property

All components must have a material assigned

Drawing sheets not in one sheet set for the entire project

The stand interferes with the use of the checking fixture
