Customizable Tool for Handling and Orientienting Magnets · 模型 206297
My source CAD file is “Magnet_Tool.ntop.txt”. To open it, remove .txt from file name and open then in nTopology. This was necessary because GrabCAD does not accept .ntop files. ************************************** My name is Joey Fisher, and I am a PhD student in Mechanical Engineering at Penn State University. After graduating, I am interested in working either as a university professor where I will teach additive manufacturing related topics, or in industry, leveraging additive manufacturing and design for additive manufacturing and further driving adoption of the technology. The application I am submitting is a tool to solve a real-life problem I had with press fitting magnets into 3D printed parts. For a project I needed to press fit 1000 small (3mmx3mm) cylindrical neodymium magnets. The magnets are very hard to handle due to their strength and small size. In addition, the polarity of the magnets was critical to my application and the ends were not marked, requiring me to keep track of the orientation of each one myself. My goal was to create something that would make inserting the magnets faster, effectively eliminate the risk of error in the process, and make it much easier on my hands. The way the tool works is illustrated in the image gallery above, as well as the linked YouTube video below. A stick of magnets is inserted into the handle piece of the tool, and a finger is used in the opening in the side to hold the magnets and push them forward as needed. The slider piece of the tool is placed on a ferromagnetic (e.g., steel) surface, and a magnet from the handle is pushed into the hole in the slider. The slider can then be pulled away from the handle along the steel, detaching a single magnet from the stack in an easy and controlled process. The part can then be pressed onto the magnet and the process is repeated. The tool I designed and used could be redesigned for, and manufactured, using traditional manufacturing. However, additive makes the most sense from both a time and cost perspective. Because the design went through several rapid iterations to achieve the fit necessary for it to be functional, additive manufacturing was the fastest way to get to a finalized tool. Because the design is fully parameterized and mass customizable, all dimensions are driven by the user’s choice of inputs (e.g., magnet diameter, length, and quantity) in nTopology, allowing for rapid changes for any future applications that use different magnets or a ...
