The video titled "Solidworks Tutorial # 259 how to design a CAR JACK in solidworks Screen Size-16:10 Ratio" from the SOLIDWORKS EASY DESIGN channel is a video teaching how to design a 3D model of a Car Jack, which is usually a Scissor Jack type that uses a scissor mechanism, using the SolidWorks program.
This video is 18 minutes and 24 seconds long and demonstrates the construction of the various sub-assemblies and their assembly into a working mechanism.
Summary of the main content of the video: Car Jack design
This video focuses on the design of parts and the assembly of complex mechanisms (Kinematic Mechanism):
1. Part Modeling
The instructor will demonstrate the construction of a model of the parts that make up the jack:
Arms/Scissor Links: Create a model of the scissor cross-link [00:20] which uses Sketch and Extrude commands, including creating mounting holes.
Top & Bottom Bases: Create the weight-bearing parts and the parts that touch the ground.01:30]
Lead Screw: Create a model of the threaded shaft [02:40] which is the key to converting rotation into vertical movement.
Drive nut (Nut/Slider): Creates a part that runs along a thread [03:50] and connect with cross legs
2. Assembly
Mechanism Assembly: Assemble all the parts in the Assembly file [05:00]
Using Mechanical Mates (Focus): This is the most important part. The instructor will use the Mate commands to create relationships that are similar to real work:
Concentric Mate: For holes and shafts
Coincident Mate: For surfaces that touch each other
Screw Mate: Used for threaded shafts [06:40] by specifying the pitch of the thread so that one revolution of the screw results in the correct longitudinal movement.
3. Motion Simulation
Functional Testing: Once all Mates are defined [09:00] The instructor will test by rotating a threaded screw (or using the Motor in the Motion Study) to demonstrate that the scissor mechanism will open and close correctly, allowing the jack to raise and lower the vehicle.
This video is therefore a good tutorial for learning how to design and model mechanisms that convert angular motion into linear motion in SolidWorks.
1. SolidWorks Tutorial: Design and Build a Car Jack with Expansion and Contraction Simulation with Screw Mate Focus on the workpiece (Car Jack) and key commands (Screw Mate) used to simulate the actual working mechanism.
2. SolidWorks Assembly: Guide to Creating Angular to Linear Motion Mechanisms Emphasis on the mechanical principle used by the jack, which is to convert the rotation of the screw into the up and down movement of the jack.
3. SolidWorks Part Modeling: Create a Scissor Jack part and define the Mate to make the mechanism work. Emphasis on the construction steps, both sub-parts and assembly, so that users who are practicing can follow along.
