Assembly & mates

  1. 1. Image courtesy of National Optical AstronomyObservatory, operated by the Association of Universitiesfor Research in Astronomy, under cooperativeagreement with the National Science Foundation.Teaching SolidWorks SoftwareLesson 4Peters Township High SchoolMr. Burns & Mr. WalshCADD Online
  2. 2. 2Features Used to Build Tutor21.Base Extrude 2.Fillets3.Shell 4.Cut Extrude
  3. 3. 3Sketch for Cut Feature Sketch is composed of two curves.– Convert Entities creates the outside curve.– Offset Entities creates the inside curve. Rather than drawing the outlines by hand, they are“copied” from existing geometry. This technique is:– Fast and easy– select the face and click the tool.– Accurate – sketch entities are “cloned” directly from existinggeometry.– Intelligent – if the solid body changes shape, the sketch updates.Automatically.
  4. 4. 4Convert Entities Copies one or more curves into the active sketch byprojecting them onto the sketch plane. Curves can be:– Edges of faces– Entities in other sketches Easy and fast– Select the face or curve.– Click the tool.
  5. 5. 5To Create the Outside Curve:1. Select the sketch plane.2. Open a new sketch.3. Select the face or curvesyou want to convert.In this case, select theface.4. Click Convert Entitieson the Sketch toolbar.
  6. 6. 6Creating the Outside Curve:5. Outside edges of face are copied into the activesketch.6. Sketch is fully defined – no dimensions needed.
  7. 7. 7To Create the Inside Curve:1. Click Offset Entities on theSketch toolbar.The PropertyManager opens.2. Enter the distance value of 2mm.3. Select one of the convertedentities.4. The Select chain option causesthe offset to go all the wayaround the contour.
  8. 8. 8Creating the Inside Curve:5. The system generates a previewof the resulting offset.6. A small arrow points towardthe cursor. If you move yourcursor to the other side of theline , the arrow changesdirection. This indicates on which sidethe offset will be created.7. Move the cursor so it is inside thecontour. Click the left mouse button tocreate the offset.
  9. 9. 9Creating the Inside Curve:8. The resulting sketch is fullydefined.9. There is only onedimension. It controls theoffset distance.
  10. 10. 10Tutor Assembly The Tutor assembly iscomprised of two parts:– Tutor1 (created in Lesson 2)– Tutor2 (created in thislesson)
  11. 11. 11Assembly Basics An assembly contains two or more parts. In an assembly, parts are referred to as components. Mates are relationships that align and fit componentstogether in an assembly. Components and their assembly are directly relatedthrough file linking. Changes in the components affect the assembly. Changes in the assembly affect the components.
  12. 12. 12To create the Tutor assembly:1. Open a newassemblydocumenttemplate.2. Open Tutor1.3. Open Tutor2.4. Arrange thewindows.
  13. 13. 13Creating the Tutor assembly:5. Drag anddrop thepart iconsinto theassemblydocument.Save theassemblyas Tutor.
  14. 14. 14Assembly Basics The first component placed intoan assembly is fixed. A fixed component cannot move. If you want to move a fixedcomponent, you mustFloat (unfix) it first. Tutor1 is added to the FeatureManager design tree withthe symbol (f). The symbol (f) indicates a fixed component.
  15. 15. 15Assembly Basics Tutor2 is added to theFeatureManager design treewith the symbol (-). The symbol (-) indicates anunderdefined component. Tutor2 is free to move and rotate.
  16. 16. 16Manipulating Components Move components by dragging. Move components with a triad. Move Component – translates(moves) the selected componentaccording to its available degreesof freedom.
  17. 17. 17Manipulating Components Rotate components by dragging. Rotate components with a triad. Rotate Component – rotates theselected component according toits available degrees of freedom.
  18. 18. 18Degrees of Freedom: There are Six They describe how anobject is free to move. Translation (movement)along X, Y, and Z axes. Rotation around X, Y, andZ axes.
  19. 19. 19Mate Relationships Mate relationships align and fit together componentsin an assembly. The Tutor assembly requires three mates to fullydefine it.The three mates are: Coincident between the topback edge of Tutor1 andthe edge of the lip on Tutor2.Tutor1Tutor2Edges
  20. 20. 20Mate Relationships Second Mate: Coincidentmate between the right faceof Tutor1 and the right faceof Tutor2. Third Mate: Coincident matebetween the top face ofTutor1 and the top faceof Tutor2.
  21. 21. 21Mates and Degrees of Freedom The first mate removes allbut two degrees offreedom. The remaining degrees offreedom are:– Movement along the edge.– Rotation around the edge.
  22. 22. 22Mates and Degrees of Freedom The second mate removes one more degree of freedom. The remaining degree of freedom is:– Rotation around the edge.
  23. 23. 23Mates and Degrees of Freedom The third mate removes last degree of freedom. No remaining degrees of freedom. The assembly is fully defined.
  24. 24. 24Additional Mate Relationships for Exercises andProjects The switchplate requires two fasteners. Create the fastener. Create the switchplate-fastener assembly.
  25. 25. 25Additional Mate Relationships for Exercises andProjects The switchplate-fastener assembly requires three matesto be fully defined. The three mates are: First Mate:Concentric matebetween the cylindricalface of the fastener andthe cylindrical face ofthe switchplate.
  26. 26. 26Additional Mate Relationships for Exercises andProjects Second Mate:Coincident mate betweenthe flat circular back face ofthe fastener and the flatfront face of the switchplate.Faces
  27. 27. 27Additional Mate Relationships for Exercises andProjects Third Mate:Parallel mate between theflat cut face of the fastenerand the flat top face of theswitchplate. The switchplate-fastenerassembly is fully defined.Faces
  28. 28. 28Additional Mate Relationships for Exercises andProjects The cdcase-storagebox assembly requires threemates to be fully defined. The three mates are: First Mate:Coincident betweenthe inside bottom faceof the storagebox andthe bottom face ofthe cdcase.Faces
  29. 29. 29Additional Mate Relationships for Exercises andProjects Second Mate:Coincident mate betweenthe inside back face ofthe storagebox and theback face of the cdcase.FacesInside back face
  30. 30. 30Additional Mate Relationships for Exercises andProjects Third Mate:Distance mate between the inside left face of thestoragebox and the left face of the cdcase. Distance = 1cm. Good job! Now,would you like to dothis 24 more times?No!Faces
  31. 31. 31Component Pattern A Component pattern isa pattern of componentsin an assembly. The Component patterncopies the SeedComponent. The Seed Componentin this example is the cdcase. This eliminates the work of adding and mating eachcdcase individually.
  32. 32. 32To Create a Linear Component Pattern:1. ClickInsert, ComponentPattern,LinearPattern.
  33. 33. 33Creating a Linear Component Pattern:2. Select the cdcase as theComponents to Pattern.3. Select the front edge of thestoragebox forPattern Direction.4. Spacing = 1cm5. Instances = 256. Click OK.
  34. 34. 34More to Explore: The Hole Wizard What determines the size of thehole?– The size of the fastener– The desired amount of clearance Normal Close Loose
