Double Slider Crank Mechanism
Class: Intro to Engineering and Design
Design the Mechanism:
- I sketched my design, focusing on dimensions and the motion path.
- I chose materials based on my design, considering what I have available.
- I calculated necessary dimensions to ensure everything fits together properly.
Gather Tools and Materials:
- I collected the tools I needed: a drill, saw, screwdriver, ruler, and protractor.
- I gathered materials like plywood, metal sheets, rods, bearings, and screws.
Fabricate the Crank and Slider:
- I cut the crank arm and made sure to include a pivot point.
- I created the slider from a block or rod that would move along a guide.
- I drilled holes for the pivot and the connecting rod attachments.
Build the Frame:
- I constructed a stable base using my chosen material.
- I installed guides for the slider, ensuring they’re aligned for smooth motion.
Electronics and Motion Setup
- I designed specific movement within the CAD software to insure that the product moved smoothly.
Assemble the Mechanism:
- I attached the crank to the frame at the pivot point.
- I connected one end of the connecting rod to the crank and the other end to the slider.
- I placed the slider in the guide rail and checked that it moves freely.
Test the Mechanism:
- I manually rotated the crank to see if the slider moves smoothly.
- I identified any issues, like binding or misalignment, and adjusted as needed.
Optimize and Finalize:
- I applied lubricant to the moving parts to reduce friction. I made any necessary adjustments to improve performance.
- I documented my work with notes and photos for my project report.
