Second Project – CAD

Overview

I made a mechanism that can open and close a claw. It is controlled by sliding one part.

Skills

Sketching

I drew a hooked stick and two straight sticks for the grabber, slider, and connection parts.

I drew a rectangle split into three sections for the shaft.

Each part has appropriate holes of diameter 5mm.

Extruding

The entire mechanism will be split into three vertical 2.5mm thick layers: Shaft Floor, Lower, and Upper.

The grabber will consist of two parts: a handle, a hook. The handle will be 1 layer and the hook is 2 layers thick.

The slider is 2 layers thick, and the connector is 1 layer thick.

The shaft is made of the shaft floor, walls, and joint. The walls and joint are on the lower layer.

Assembly

I connected the grabber to connectors and connectors to the slider with revolve mates.

Excellent work on the CAD side of this assignment, Aston! You have demonstrated all of your needed skills and did a great job of the mechanical drawing! It would be fun to see this through to see if you can get the full assembly to operate as you envision it. Each mate works properly on it’s own, but the full mechanism doesn’t work as a unit. Not a concer for the assignment, but might be fun and useful to figure out.

Can I ask that you spend a little more time on the written portion of these blog posts. Someone coming to your post for the first time, isn’t going to understand the context of it and that it is an assignment for a course that you are taking in the Fusion Cohort. Empathize with your general reader. Will they understand what you are talking about?
