Given the complexity of visualizing and drawing technical diagrams without visual aids, we can go through the conceptual steps to create the assembly drawing of a knuckle joint, including a half -sectional view, or front view, a top view, and how to indicate the bill of materials and projection symbol.
00:31
This will be a conceptual guide rather than a precise drawing.
00:36
Instruction due to the limitations of this format.
00:43
So the first step to take consideration of is understanding the components.
01:07
So here we have first the fork end.
01:22
This part has two prongs with holes at the ends that align with the hole in the end when assembled.
01:34
So next we have the eye end.
01:45
This this is a single piece with a hole that aligns with the holes in the fork end to accomplish the pin.
01:59
So then the drawing of pin accomplishment across the design makes its accommodation precedent.
02:20
So then we focus on the pin, a cylindrical piece that goes through the aligned holes of the fork.
02:34
And eye rods.
02:38
So these irons have their ends, and then they're then secured together.
02:58
So next we have, if we look on the shop drawing, the collar, a small cylindrical piece that fits on one end of the pin to prevent it from sliding out.
03:21
So then lastly, we have the taper pin.
03:33
A pin that is used to secure the collar to the main pin.
03:44
So now we move on to the next step, drawing the half section front view.
03:55
So again, there's other ways of projecting the drawing either orthographically or isometrically, but the concept in interpreting the drawing dimensions with respect to the function are key.
04:10
So then if you run into another, format this is not so much an issue we're looking for a perspective so start with the fork end draw the fork end with one of the prong section in half along its length to show the internal material so in other words you want to then draw a cross sectional perspective or projection of the prongs or prongs sectioned in half across its length to show the internal material.
04:50
So this involves drawing the outer contour and then adding a hatch pattern to the sectioned area.
04:59
So you can start by internal perspective.
05:25
So then we can add the eye end.
05:28
Since this is a half sectional view, the eye end will be shown in.
05:35
In full, not sectioned, attached to the non -sectioned prong of the fork end.
05:49
Full view attached.
05:59
I'll call that attachment.
06:06
So then we have insert the pin...
