SolidWorks assembly assignments often present challenges that require a deep understanding of 3D modeling, assembly techniques, and problem-solving skills. In this blog post, we'll delve into two master-level SolidWorks assembly questions, each followed by a detailed solution crafted by our seasoned SolidWorks experts.

Question 1: Designing a Mechanical Assembly

Imagine you are tasked with designing a mechanical assembly consisting of several components that simulate a real-world engineering scenario. Your goal is to create an assembly that includes the following components:

1. Base Plate: A simple rectangular plate with specific dimensions.
2. Shaft: A cylindrical shaft that fits through a hole in the base plate.
3. Bearing: A standard bearing that mounts onto the shaft.
4. Pulley: A pulley that attaches to the shaft and rotates freely.

Requirements:

• The shaft must be concentric with the hole in the base plate.
• The bearing should be positioned correctly on the shaft to allow smooth rotation.
• The pulley must be fixed firmly to the shaft and rotate with it.

Solution Approach:

1. Creating the Base Plate:

   • Start by sketching a rectangle on the top plane and extrude it to the required thickness to create the base plate.

2. Designing the Shaft:

   • Sketch a circle on the top plane and extrude it to create the cylindrical shaft.
   • Ensure that the diameter of the shaft matches the diameter of the hole in the base plate for concentricity.

3. Adding the Bearing:

   • Insert the bearing component into the assembly.
   • Use mates to position the bearing concentrically with the shaft.

4. Attaching the Pulley:

   • Insert the pulley component onto the shaft.
   • Use a concentric mate to ensure the pulley rotates with the shaft.

5. Final Adjustments:

   • Apply additional mates as needed to secure the components in place and verify motion.

Question 2: Assembly with Motion Constraints

Now, let's consider a more advanced scenario where the assembly involves moving parts with specific motion constraints.

Scenario: You are required to design an assembly comprising a crankshaft, a connecting rod, and a piston. The assembly should demonstrate realistic motion where the crankshaft rotates, causing the piston to move up and down within a cylinder. The connecting rod should maintain proper connections and motion constraints between the crankshaft and the piston.

Requirements:

• The crankshaft should rotate smoothly.
• The connecting rod must maintain a fixed length and connect the crankshaft to the piston.
• The piston should move vertically within the cylinder as the crankshaft rotates.

Solution Approach:

1. Designing the Crankshaft and Piston:

   • Start by creating the crankshaft and piston components separately.

2. Adding the Connecting Rod:

   • Insert the connecting rod between the crankshaft and the piston.
   • Use mates (such as coincident and tangent) to establish the correct connections and motion constraints.

3. Defining the Motion:

   • Utilize the Motion Study feature in SolidWorks to simulate the motion of the crankshaft.
   • Specify the rotation of the crankshaft and observe the resulting movement of the piston.

4. Verifying Constraints:

   • Check that the connecting rod maintains its length and the piston moves as expected during the motion simulation.

5. Fine-Tuning:

   • Adjust mates and motion parameters as necessary to achieve realistic and accurate motion.

By following these steps and employing SolidWorks' powerful assembly tools, you can effectively model and simulate complex mechanical assemblies with precision and clarity.
