44691R Quality Control: Screw Standoff
Entry ID #: 8372
Created: Fri, Dec 4, 2020 9:58 AM
My team created the screw standoff. This standoff is like a normal standoff, but with a twist. This standoff has one end with a screw hole like any other vex standoff, but the other end has a screw. This part was created for several reasons. The first reason my team created this part was to get rid of the hassle of having to cut a screw to connect two standoffs together. Another is to also allow the reuse of the standoff, since when normally teams cut the screw and put it into the standoff, the screw sometimes screws into one of the standoffs and is unable to come out, resulting in that standoff being unusable. Finally, the last reason my team created this part is it reinforces the connection of the standoffs, since the screw connecting the two standoffs can’t unscrew from both of them, creating less of support or whatever the team used them for.
Purpose of the part:
The part could be used in multiple ways, but my team mainly used multiple parts that would act the same as this part would for support. Last year, my team connected two 6 inch standoffs together with shaft collars on the end as support for the back part holding the arms and cortex of the robot. For that, we had to cut 6 screws to connect all those pieces, but if we were to use this, then it would reduce the amount of cutting and still work the same with us having to cut only two screws, and it would still hold up the back part.
Part Designing Process:
To create the screw standoff part, I used Fusion 360, version 2.0.9313. I began by creating a sketch of a circle with a diameter of 0.25 in, which is the dimension of a normal standoff that I found on the vex website. Then I created a line going out from the center out of the edge of the circle. Then did a circular pattern to create six of the same lines to create a hexagon that is the same as a normal standoff. Then I extruded the sketch by an inch. After that I created a exturde of a 0.164 in cylinder on one side , an indent on the same object on the other. Then I created the screw threads on the cylinders to finish the part!
When using fusion 360, I got to learn how to add screw threads on this program while I had only known how to do it on fusion. I’ve been using Fusion more frequently and will continue to use it to design parts and projects, for fun projects and for robotics. While being on a competitive robotics team, it allowed everyone to create parts in a fast, fun, and easy way to help our robot become its best. Finally, learning it will hopefully help my team and I in the future, not just for robotics, but whatever fields that we go into.
