Here you will create few parts using some of the features you became familiar during the last week. You will also learn some advanced features of this tool today. Assume that you are working in a company where most of the projects are accomplished in teams. Some of your colleagues had created a few designs and your manager had assigned you a task to take those designs, create few more parts and generate an assembly of it. You are also given a timeline to complete the task. Failure to do so will result in you being fired (in your case getting a lower grade). Your manager had given your team an image of the design you need to create. Your team had already completed the major task of designing the cylinder with the clevis joint. Below is an image of the part your other team members had completed. 2 You are required to complete the above drawing by designing the Axle (Green in color), Shaft collar (Yellow in color) and Flat bar (Red in color). Once you had created the above parts you need to assemble them to generate the above design. A sample image of parts you need to create is shown below. From the knowledge of Solid works you gained in the last week’s lab, we assume that you will be able to create the Axle and Shaft collar with ease. Follow the specifications given below for the Axle and Shaft collar. 5 7. After completing the above step, you should have the figure 3(a) on your desktop. Now repeat step 6 for the vertical line on the right side of the rectangle to obtain figure 3(b). Figure 3(a) Figure 3(b) 6 8. After performing the Trim operation we select the small sections of left over side lines (turns blue when clicked on) and delete them to obtain figure 4. Figure 4 9. Right click on the mouse bottom as you will notice figure 5(a) on your screen. Click on the 3 point arc icon. Figure 4 Figure 4 Figure 5 7 10. Click on the right edges of the two parallel lines and extend the arc to the right until a dotted line perpendicular to the solid lines appears on the screen (figure 6(a)). Repeat the same procedure for the left side. After completing the above steps the model should resemble figure 9(b). Figure 9(a) Figure 9(b) 11. Click on the top line of the drawing. 12. Enter “101.60” in the Length Column of the Parameters block as appears below and click OK. 10 17. Click on Extruded Cut on the Features Toolbar 18. Change from Blind to Through All in the direction of cut to obtain the figure below. Figure 14 19. Click on Linear Pattern on the Features Toolbar and click on the Top Front edge of the Flat bar (Make sure the arrow is pointing towards the right as shown below. If not click Reverse near the direction column). 20. Enter “12.70” in the Distance column and “9” in the Number of Instances in the Direction 1 column as below and click OK Figure 15 11 21. Save your part as “Flatbar.Sldprt”. Steps to follow for the Assembly: Open all the necessary files: a. CYLINDER.SLDASM, b. Flatbar.SLDPRT c. Collar.SLDPRT d. Axle.SLDPRT 1. Create a new file of assembly type by clicking on Click on File New 3D arrangement of parts and other assemblies ok. 2. Click on Window Tile Horizontal on the Menu bar. 3. Insert the Cylinder assembly and all the parts into the new assembly file by clicking and dragging the top icon in the design tree of each file 4. Make sure to insert two Flat bars and Collars into the assembly. 5. Close all the files except the new assembly file. 6. Move & Rotate all the parts to get a view approximately as shown below by using the Move and Rotate icons on the Feature Toolbar. Figure 16 12 7. Zoom to the area of the Clevis and click on Mate in the Features Toolbar . 8. Click on the outer edges of the Clevis and Axle as shown below and click OK. Figure 17 9. We will notice the axle aligning itself along the hole. Click on the “Move component” icon in the toolbar and drag the axle through the clevis to obtain model shown in figure 18 (b) Figure 18(a) Figure 18(b) 15 Figure 22(b) 15. You will observe that the Collar will move onto the Axle to a position which avoids the Flat bar from falling off. Repeat the same procedure (Steps 14) for the other collar and get the axle joint as below. Figure 23 16 16. If you reach this point doing all the labs by yourself, you will be able to take the exam next week with ease. Call your GTA to show the work and get your grade. You deserve a good grade for this complex task. References: 1. Dr.Kumar Yelamarthi, Assistant Professor, Department of Electrical Engineering, Central Michigan University. 2.
