Rotation to Linear Motion Transformer

thingiverse

This is a linear motion transformation device I designed and built for a robotics competition at Umeå University in Sweden, where it will be used to pop balloons with a needle attached to the front of its shaft. To assemble this device, you'll need the following components in addition to the 3D printed parts: 1 x DC Motor (see example link below) 2 x 623 Bearings 1 x LM6UU Bushing 4 x M4 Threaded rods, each 120mm long 1 x M6 Smooth rod, 65mm long 8 x M4 Nylock nuts 8 x M4 Nuts (with 2 extra for mounting holes) 2 x M3 Screws, 16mm long 2 x M3 Screws, 12mm long 1 x M3 Screw, 20mm long 1 x M3 Threaded rod, 45mm long 2 x M3 Washers 6 x M3 Nuts (preferably 3 Nylock nuts for bearing mounting holes) The DC Motor I used is recommended for this project. To prevent wear and tear, I suggest placing washers between the M3 screws or nuts and the 3D printed components. A dwf file has been included to help you visualize where each component should be placed. Unfortunately, I didn't create a tutorial on how to build this device from scratch, but it's included as a no-text version of the anterior mount. I hope you enjoy building and using this device!
