Home Assignment 1 (HA1): Steering Wheel Lock Hold Tool Create 3 Part Models, one for each of the 3 Items explained below

1 U-shape

Dimensions of the “U” shape:

This shape was manufactured by bending ¼”x1” bar .

Inner Width of U = 3”

Inner Height of U = 3.125”

Outer radius of U = 7/16”

Inner radius of “U” = 3/16”.

Hole diameter = 0.59” and is centered on the bottom face of the U.

Fillet on the corners of the bar must be less than ½ the bar thickness.

2 Nut:

Shape = Hexagonal

Width across flats = (7/8)” [Find out what across flats means!]

Thickness = 0.5”

Inner Diameter (I.D.) = 0.479”

3 Washer:

Outer.Diameter. = 1.175”

Inner Diameter = 0.585” I.D.

Thickness = 0.065”

Please , each part is a separate piece, they are to be made separately. Thanks a lot

Explanation / Answer

The components are very simple to draw but simply keep in mind the dimensions.

Step- 1

Make a 2D figure of U- shape with internal dimensions and then same way draw outer dimensions and make them close loop.

Keep in mind-

Inner width and inner height will be given as per dimension.

but, for outer drawing the thickness will be equal to difference of outer red and inner radius.

chhose extrude command taking thickness section as reference and take dimension of depth accordingly.

Fillet can also be provided after extrude command.

Step 2- Washer

Now, choose the plane in which hole is to be drawn, means select bottom plane.

Draw outer circle of dia same as width of bottom plane taking centre as mid of bottom plane.

draw a concentric inner circle specified dimension.

now again choose extrude command and select the section other than hole for extrusion . give appropriate thickness.

Step 3-

Nut

choose an offset plane parallel to bottom plane and if there is hexagon command then select hte same and draw and then extrude accordingly. otherwise it can be drawn manually by taking line command and then extrusion. To make a hole in the hexagon select its face and draw a circle of given dimension and then extrude the through hole taking the drawn circle as reference.

Your model is ready.
