To do so, you need to start a new SolidWorks assembly document. 1. Start a new SolidWorks assembly document; the Insert Component PropertyManager is invoked automatically and the names of components, which were opened, are displayed in the Open documents selection box. 2. Select the Vice Body from the Open documents selection box; the preview of the Vice Body is displayed along with the component cursor. 3. Choose the Keep Visible button from the Insert Component PropertyManager because after placing this component, you also need to place the second component that is displayed in the Open documents selection box. It is recommended that the first component of the assembly should be placed at the assembly origin. 4. Choose the OK button from the Insert Component PropertyManager to place the first component coincident to the origin. As the Keep Visible button is selected, the preview of the Vice Body is again displayed with the component cursor in the drawing area. 5. Change the current view to isometric. Next, you need to place the second component in the assembly. As discussed earlier, the second component of the assembly, which is the Vice Jaw, is assembled with the Vice Body using the mate references. Assembly Modeling-I 12-39 6. Select the Vice Jaw from the Open documents selection box; the preview of the Vice Jaw is available in the drawing area. When you move the cursor close to the Vice Body in the assembly document, the preview of the Vice Jaw assembled after applying the mates with the Vice Body is displayed in the assembly document. 7. Place the component at the required location. The mates specified in the mate references are applied between the Vice Jaw and the Vice Body. Choose the Keep Visible button and exit the Mate PropertyManager. Figure 12-58 shows the second component being placed in the assembly document and Figure 12-59 shows the isometric view of the Vice Jaw assembled with the Vice Body. Figure 12-58 Second component being placed 8. Before proceeding further, it is recommended that you close all the part documents. Close the part document windows of all the parts that are placed in the assembly document. Tip. The mates that are defined in the mate reference are applied to the components when you place the components in the assembly. You can view the mates applied to both components by expanding the Mates option from the FeatureManager Design Tree of the assembly document. Copy. For www.cadcim.com Evaluation Copy.

Choose the Add/Finish Mate button from the Mate pop-up toolbar. The assembly after adding the Coincident mate is displayed in Figure 12-66. Figure 12-66 Assembly after applying the Coincident mate to the Jaw Screw In real world, there are two types of assemblies. The first is the fully defined assembly in which all degrees of freedom of all components are restricted. The other type of assembly is that in which some degrees of freedom of the components are left free so that they can be moved or rotated. These types of assemblies are used for the mechanism, about which you will learn in the next chapter. After adding the Coincident mate, you need to move the assembly to analyze the degree of freedom of the components of the assembly. After analyzing the components of an assembly, you need to add the mates to constrain that degree of freedom. Assembly Modeling-I 12-43 11. Select the circular face of the Jaw Screw using the left mouse button and drag the cursor. You will notice that the Jaw Screw is rotating about its axis and is moving along the X axis. Also, it is forcing the Vice Jaw to move along the X axis. Originally, this degree of freedom of the Vice Jaw and Jaw Screw needs to be left free so that the assembly can function in the mechanism. But in this chapter, you need to restrict this degree of freedom so as to create a fully defined assembly. 12. Select the two faces, one of the Vice Body and the other of the Jaw Screw, as shown in Figures 12-67 and 12-68. Figure 12-67 Face to be selected Figure 12-68 Face to be selected 13.
