Use McMaster-Carr parts in a design

Use McMaster-Carr parts in a design.

00:08

In this video, we’ll insert a McMaster-Carr component.

00:13

In Fusion 360, we want to carry on with our gear reduction housing assembly.

00:17

At this point, we're going to talk about inserting hardware into the design.

00:22

So the first step in this process is to use Inspect and measure the geometry.

00:27

First we want to inspect the diameter and in this case, you'll see that it's 6 mm.

00:33

And then we want to inspect the overall length.

00:36

So you'll note that this is 16 mm as the minimum distance.

00:41

Depending on the design, you might have a threaded portion of the housing,

00:46

or you might have to have a bolt go all the way through with a nut on the backside.

00:50

For this specific design, we're going to talk about using a threaded portion in the housing.

00:55

So we want to make sure that our hardware is less than 16 mm, so it doesn't stick through.

01:02

It's also important to note that this hole here is a bit longer.

01:07

And you can see that it's 24 mm.

01:10

So if we're going to be using a bolt to hold the front housing all the way to the back housing, we need to make sure that we account for that.

01:18

We can do this by going all the way from the front housing, all the way to the back, a distance of 27 mm.

01:25

So we're looking at about a 15 millimeter bolt and a 25 millimeter bolt.

01:30

Next thing we want to do is we want to insert hardware from McMaster-Carr.

01:35

It's not required that you use McMaster-Carr,

01:38

but there's already an add-inn inside of insert that allows us to navigate the McMaster-Carr website and inserted as a 3D model.

01:47

So this can be extremely handy, especially if you use McMaster for your hardware.

01:52

The first thing that I want to do is I want to resize this so it's a bit easier to see.

01:57

Then I want to begin navigating by going to screws and bolts, setting my system of measurement to metric and then determining my thread size.

02:06

In this case, we're going to be using an M6.

02:10

Next, we want to talk about the length of hardware and the head type.

02:15

The first bolt that we're going to use is a 15 millimeter long bolt.

02:19

Then I can determine the type of head that is required for this design.

02:24

In most cases, we would likely go straight to a socket head but in this case I'm going to select a rounded head.

02:30

From here, we have two choices, a stainless steel and a metric alloy steel button head.

02:37

When we look at these two choices,

02:39

it's important to understand the differences between our material choices and whether or not they work in our structural applications.

02:48

For example, the difference between a stainless steel bolt and this alloy steel is about 100,000 psi in tensile strength.

02:57

So going from 70 to 170 is quite a big difference.

03:00

So if your design is requiring a structural piece of hardware, then you need to make sure that you take these things into account.

03:08

Also note that the alloy steel button head is actually a black oxide which is essentially a sacrificial coding.

03:15

This alloy steel screw is only mildly corrosion resistant.

03:19

This means that if there's any humidity or moisture in the environment, this is likely going to rust relatively quickly.

03:26

Notice that it does have blue-dyed zinc plating as an option.

03:31

But again we need to be careful with our material choices.

03:36

For our example, it's not going to matter.

03:38

So I'm going to use the metric alloy steel button head because the geometry is going to be exactly the same.

03:45

Once I select the part number, the next thing I need to do is select the file type as a 3D Step but note that they have a 3D Step with no threads.

03:55

Depending on your specific needs and also how much hardware you need, you can pick the one with no threads because it'll be less intensive on the CPU.

04:05

For our example, however, I will be using the 3D Step and then I'll select Download.

04:11

When we select download, it's placed as a component inside of our browser and then we can manipulate it using Move/Copy.

04:18

I'm going to begin by rotating at 90 degrees and then I simply want to move it out away from the housing and I'll select Capture Position and OK.

04:28

While this isn't the final location, I do want to make sure that it is visible on the screen,

04:33

and then I can go back and use insert McMaster-Carr and find another bolt that matches.

04:41

So we're going to expand the window again.

04:44

We're going to take a look at those rounded head screws, metric,

04:48

make sure that it's M6 and this time we're going to be using a 25 millimeter long screw.

04:55

Notice that we have a few more options here.

04:58

Because we want to make sure that we use the same type, I'm going to select black oxide and note that we have three different ones.

05:05

We have a metric alloy steel button head.

05:08

Then we also have a stainless steel that has black oxide coating.

05:12

And then we have one with a Phillips head.

05:15

We're going to take a look at the metric alloy steel that's similar to the one that we already selected.

05:20

And we're going to download that as well.

05:23

You'll also know when you're selecting hardware from McMaster-Carr that the part numbers are going to be representative of the geometry.

05:31

So in this case 91239A and we have an 813 and a 327.

05:37

So the first portion of the part number is the same and the second portion is different based on the size.

05:43

So we're going to capture its position and now that I have these two pieces of hardware in place,

05:48

I can use things like Move/Copy or Align to put them in the correct position.

05:54

It's also important to note that we can use joints to align them to the correct position, but we haven't learned about joints yet.

06:01

So we're going to focus on a tool that we already know and that's Modify and Align.

06:06

We're going to make sure that it's set to components and we're going to begin with the larger hardware.

06:12

I'm going to hover over the bottom face, hold down control or command and then go to the center position of the bolt.

06:18

Going to rotate around, hover over the face of my front cover, hold down control or command and then move to that position and will select Capture.

06:27

Using my right click marking menu we're gonna repeat the align on the other piece of hardware.

06:34

So we want to rotate it around again, hold down control or command to find the center of that bolt.

06:40

If you chose to use one of the Step files without threads on it, the selection process is a little bit easier.

06:46

Then we want to select its position.

06:49

We're going to capture its position and we're going to say, OK.

06:53

Because we know that we use symmetry when designing this housing,

06:57

this means that we can use things like mirrors or patterns in order to fill the rest of the positions.

07:04

This could be done with a circular pattern for the outside of the housing or we can use a mirror.

07:10

In order to do that, however, I need to place one of the bolts in this other location and then I can mirror it top to bottom.

07:18

In order to do that, I'm going to take the long bolt, I'm going to right click and I want to copy it, then I'll right click and I'll paste it.

07:28

When I paste it, you'll notice that it's a second instance of the same bolt.

07:34

I'm going to manually move it off to the side and then I'm going to use my Modify and Align.

07:39

And once again select the bottom of the bolt holding down control or command to select that center point,

07:48

and then we'll do the same thing on the housing.

07:51

We’ll capture its position and then we'll say, OK.

07:55

Now that we have the hardware in place, I'm going to go to Create and I'm going to select Mirror.

08:00

I'm going to start by selecting components.

08:03

The component that I want is the shorter hardware and the mirror plane is going to be the default YZ plane in this case.

08:13

We'll say, OK and note that now we have a mirrored version of it here.

08:17

Once again, when we take a look at the components, when we have a mirrored version, you'll note that it actually creates a new component.

08:25

When we have a copy, it's the same component but a second instance.

08:30

This is problematic when we get downstream and we begin talking about creating things like bill of materials and parts lists,

08:37

because the mirrored version of the component is an opposite handed version.

08:42

If we right click on the mirror featuring edit, we don't have an option to actually create an identical component.

08:50

So if you are worried about the bill of materials downstream, then using something like mirror is not a good option.

08:57

So we're going to select Mirror in the timeline and select Delete.

09:01

Then from the Create menu, if we go to Pattern and select Circular Pattern, we'll set it to Components.

09:09

We'll select a short hardware and then for the axis, we just need to select the center of revolution, the number of instances and then we can say, OK.

09:20

Now if we look at the name of the hardware, you can see that it has a colon and a 4 after it for the fourth instance,

09:27

the third instance, the second instance and then back to the original is the first.

09:31

This means that on a bill of materials they'll show up as quantity 4.

09:36

We need to do the same thing for the longer hardware but unfortunately, we don't have a pattern that will work for those.

09:44

So really that comes down to creating copies and moving them into position with Align.

09:49

So that's a great opportunity to play around with Align and using Copy and Paste.

09:55

So go ahead and save this design.

09:58

Then use Copy and Paste and Align to take both of these pieces of hardware and create a new copy of them inside of the other two positions.

10:08

From there go ahead and move on to the next step.
