Step 1
Draw a full-size sectional elevation on A-A, showing the parts fully assembled
Answer
To draw the full-size sectional elevation of the can crusher:
- Begin with the base and outline it accurately, ensuring to include the cylindrical boss for the vertical slide rod.
- Draw the vertical slide rod and ensure the correct dimensions are celebrated.
- Include the link plate in its vertical position with the necessary detailing for holes and dimensions.
- Draw the hinge plate, focusing on the outline and inner details accurately.
- Incorporate the moving jaw in its highest position, accurately showing the outline and inner details.
- Ensure the handle is drawn with specifications for correct height and width.
- Complete the drawing with accurate representation of tension springs and appropriate hatching and centerlines.
Step 2
Determine, and indicate on your drawing, the maximum angle of rotation of part 5 when the crusher is in use
Answer
To find the maximum angle of rotation of part 5 (the link plate) when the crusher is in use:
- Identify point D on the base and point R at the top of part 5.
- Reference distance QR, establishing it in a horizontal orientation on the drawing.
- Note that the angle of rotation should not exceed 20° from its vertical position, with P directed downward.
- Indicate the maximum rotation angle clearly on your drawing, marking it appropriately.
