Add The Spot Welds To The Drawing For The Dr

Add the Spot Welds to the Drawing for the Dr

For Homework 10, you will add the spot welds to the drawing for the drawer from HW09, create a drawer assembly, and produce an appropriately dimensioned and annotated drawer assembly drawing. This involves modifying your existing HW09 drawing to include spot weld indicators, creating an assembly with your drawer and handle components, and developing a comprehensive assembly drawing with views, dimensions, weld notes, and a Bill of Materials (BOM).

Paper For Above instruction

The task begins with updating the existing HW09 drawer drawing by incorporating spot weld symbols on the corner flaps of the bin. These welds are to be represented as circles with a minimum diameter of 2 mm, positioned on each of the two flaps in the right view. Centerlines, relevant dimensions, and weld symbol annotations are to be added in accordance with standard practices outlined in Lesson 12 slides, ensuring clarity in weld placement and specifications.

Next, the project progresses to creating a 3D weldment assembly in SolidWorks by combining the HW09 drawer-bins with a handle component sourced from the assignment on Isidore. A new assembly document, named DRAWER-ASM.SLDASM, should be created in millimeter units. The assembly begins with the HW09 drawer-bins, to which the handle component is added. The handle must be positioned precisely: centered on the drawer, 5 mm from the top, and flush against the front. To facilitate accurate assembly, construction of center planes on each part is recommended, simplifying the alignment process.

Once positioned correctly, four fillet weld beads are to be added between the handle and the drawer. Each weld bead should be 1.2 mm wide and located along the vertical edges of the handle where it meets the drawer. The welds should be 7.5 mm in length, starting at the top of the vertical edges. Activate the 'Weld Bead' view to visualize these welds within the assembly, ensuring they are properly placed and sized in accordance with engineering standards.

The final step involves producing a detailed assembly drawing in D-sized ANSI-MM format. This drawing should include three orthographic views: Front, Right, and Top, along with a full or half-sized isometric view positioned in the upper right corner. Additionally, a section view sliced through the center of the front view with a vertical section line is to be included for enhanced clarity. Dimensioning of the overall length, width, and depth of the assembly is necessary, along with detailed measurements to precisely locate the handle relative to the drawer, ensuring proper fit and assembly.

Weld notes should be added to specify the four fillet welds, employing concise annotations like “2X” to indicate duplicated welds with a single note. The notes should clearly describe the weld type and locations. The drawing should also feature a Bill of Materials (BOM), assigning unique part numbers and descriptions to both the handle and the drawer. Each part should be marked with balloons pointing to their respective components in the views, facilitating easy identification.

Finally, preparing a comprehensive ZIP file should include the parts (HW09 drawer and handle), the modified HW09 drawing with welds, the new assembly (DRAWER-ASM.SLDASM), and the assembly drawing. Proper organization and accurate documentation are crucial for submission, ensuring all components and views are correctly linked and annotated, following engineering drawing standards.
