Ceiling Hook: -- Modelling and apply motion in it through Drive Constraint

  1. Create a New ‘Standard (in).ipt’ Part file.
  2. Create a new sketch on XY Plane of Part.
  3. Draw a Circle of 0.43800 inch diameter, coincident with Auto projected part origin.
  4. Draw a Line of length 0.25 inch parallel to Y axis.
  5. The midpoint of this line should lie on the X axis.
  6. Apply a Coincident Constraint between the end point of the line and the periphery of the circle.
  7. Create a new Line by taking the offset of this chord.
  8. Give the dimension of 0.15625 inch on this line.
  9. This line should be 1.5 inch away from the chord and its midpoint should lie on X axis.
  10. Start Line tool and join both the ends of this line with the end points of chord of circle.
  11. Convert all the sketches into construction geometry.
  12. Start the Centre Point Arc tool.
  13. Select the Auto projected part origin first then the end points of chord of the circle.
  14. Finish the sketch by clicking the Finish Sketch Icon.
  15. Create a new sketch on XZ plane.
  16. Take the project of last drawn arc and convert it to construction geometry.
  17. Create a circle of .094 inch diameter on the end point of this projected line.
  18. Finish the sketch.
  19. Activate Sweep Tool from the Create Panel of Model Tab.
  20. It will automatically select the small circle created on the Sketch2 as Profile and arc drawn on Sketch1 as path.
  21. Click OK.
  22. Change the Model colour to Flaked Reflective-Beige.
  23. Save the Part file with the name ‘Hook’.
  24. Open the visibility of Sketch1 in Browser Bar.
  25. Create a new Work Plane on this point parallel to YZ Plane of the Part.
  26. Draw a sketch on this work plan.
  27. Take the project of end point of the vertical line.
  28. Draw a Circle of 0.0625 inch diameter.
  29. Finish the sketch.
  30. Start Loft Tool, select small circle and circular edge of the part.
  31. Click OK.
  32. Close the visibility of Sketch1 and Work Plane1.
  33. Start Mirror tool from the Pattern panel of Model Tab.
  34. Select Loft1 from the Browser Bar as feature.
  35. Select XZ Plane from the Browser Bar as Mirror Plane.
  36. Click OK.
  37. Save the file and close it.
  38. Create a New ‘Standard (in).ipt’ Part file.
  39. Create a new sketch on XY Plane of Part.
  40. Draw a Circle of 1 inch diameter, coincident with Auto projected part origin.
  41. Finish the sketch by clicking the Finish Sketch Icon.
  42. Create a new sketch on XZ plane.
  43. Take the Project of big circle and convert it to construction geometry.
  44. Create a circle of 0.094 inch diameter on the end point of this projected line.
  45. Finish the sketch.
  46. Start Sweep Tool, select small circle as profile and select big circle as path.
  47. Click OK.
  48. Change the Model colour to Flaked Reflective-Beige.
  49. Save the file with the name ‘Circular Ring’ and close it.
  50. Create a New ‘Standard (in).iam’ Assembly and Save it with the name ‘Ceiling Hook’.
  51. Select Place Component from the marking menu and place the ‘Hook’ in the Assembly.
  52. Place ‘Circular Ring’ in the Assembly.
  53. Align the Circular Ring according to Hook by using Rotate Component Tool.
  54. Apply a Tangent Mate between Circular Ring and Hook.
  55. Apply a Mate Constraint between XY Plane of Assembly and YZ Plane of Circular Ring.
  56. Edit the Circular Ring in the Assembly by double clicking it.
  57. Activate Work Axis Command.
  58. First select the Centre Point of Hook, then the Z Axis of Hook from the Browser Bar.
  59. In this way a new Work Axis which is Adaptive to Z Axis of Hook is created.
  60. Return to Assembly by clicking Return Icon.
  61. Suppress the Tangent Mate from the Browser Bar, which was applied earlier.
  62. Now the Circular Ring is ready to move along the Hook.
  63. Create an Axis in the Assembly on the basis of two points on the periphery of Hook as displayed.
  64. Go to Work Features panel and click the drop down of Work Plane command.
  65. Select ‘Angle to Plane around Edge’ command.
  66. First select XY Plane of Assembly, then select Work Axis1 of Assembly.
  67. Click OK.
  68. Activate an Angle Constraint, first select Work Plane1 of the Assembly, then select XY Plane of Circular Ring and at last select XY Plane of Assembly.
  69. Click OK.
  70. Open the visibility of XZ Plane of Assembly.
  71. Measure the Angle between XZ Plane of Assembly and Work Plane1 of Assembly.
  72. The magnitude of this angle is 145.2 degree.
  73. Click the Selection drop drown menu and choose ‘Select Sketch Features’ command in the Quick Access Toolbar.
  74. Close the visibility of unnecessary work planes and work axis.
  75. Set the browser from Assembly View to Modeling View by using the Toggle at the top of the Browser Bar.
  76. Select the Angle:2 constraint under the Constraints folder in the Browser Bar and Change its name as ‘Drive’ by clicking twice slowly.
  77. Right click the ‘Drive’ Constraint and select ‘Drive Constraint’ Tool from the context menu.
  78. In the Drive Constraint dialog box, set the End value to (145.2*2) degree.
  79. Click the more button to expand the dialog box, enter the value 0.5 degree in the ‘Increment’ field.
  80. Clear the screen by activating the Clean Screen command.
  81. Click the Forward Button to display motion in ‘Ceiling Hook’.
  82. Click Reverse Button to return at previous position.
