Modeling and Simulating a Machine Vice in SolidWorks: A Comprehensive Guide

In today's blog, we’ll explore how to model and simulate a machine vice using SolidWorks, part of our Multibody Dynamics using SolidWorks series. This machine vice assembly is used to hold workpieces during operations such as drilling and milling. We’ll cover designing the individual parts, multibody dynamics assembly SolidWorks, and preparing for the multibody dynamics simulation.

Step 1: Understanding the Machine Vice

The vice consists of two primary components: the stationary jaw and the moving jaw. The stationary jaw, mounted on the base, remains immobile, while the moving jaw tightens around the workpiece using a handle. In this SolidWorks course, we’ll design these components step by step.

Step 2: Designing the Stationary Jaw

1. Open a New Part: Begin by opening File > New > Part and ensure the unit system is set to millimeters.
2. Base Design: Using the Center Rectangle Tool, sketch a rectangle on the Top Plane. Set dimensions to 175 mm x 100 mm using Smart Dimensions.
3. Extrude: Convert the sketch into a 3D model using the Extruded Boss/Base tool, extruding it by 10 mm.
4. Adding Mounts: Sketch a smaller rectangle on top of the base and extrude it by 5 mm to create the mounting component.

Step 3: Adding a Nut and Thread

We’ll now add a threaded nut, an essential feature of the vice:

1. Sketch the Nut: On the Front Plane, use the Circle Tool to draw a 12.5 mm diameter circle and add a concentric circle offset by 1.5 mm.
2. Extrude: Use the Midplane Option to extrude 2.5 mm on each side.
3. Thread Feature: Use the Search Command to find the Thread Tool. Apply an M24 x 2.0 metric thread on the top edge, ensuring the extrude thread option is selected.

This process covers an essential part of SolidWorks simulation for mechanical engineering.

Step 4: Adding Fillets and Additional Features

Fillets: Apply a 5 mm fillet to the four corners of the rectangle using the Fillet Tool.

Extrusions: Mirror the extrusions on the opposite side using the Offset feature. This saves time and ensures precision, an essential skill in SolidWorks design projects.

Step 5: Designing the Moving Jaw

We’ll be designing the moving jaw next:

1. Create the Jaw: Use the Corner Rectangle Tool to sketch and extrude the moving jaw. Apply constraints and dimensions to ensure everything is aligned.
2. Extrude: As before, extrude this part by 5 mm and apply fillets where needed. We will assemble this with the stationary jaw in a future step.

Step 6: Finalizing the Model for Simulation

Once the components are ready, we can move to the multibody dynamics assembly:

1. Prepare for Assembly: Use the SolidWorks assembly tutorial tools to align the parts and prepare for motion simulation.
2. Save the Stationary Jaw: Save the part as Stationary Jaw. In the next post, we’ll cover the multibody dynamics simulation for the complete machine vice assembly.
