Title: SolidWorks Tutorial | Design and Assembly of Car Jack in Solidworks | SolidWorks

This tutorial demonstrates the step-by-step design and assembly process of a car jack using SolidWorks. The video guides viewers through creating individual parts, applying features, and assembling the complete model. It emphasizes practical CAD modeling techniques such as sketching, dimensioning, extruding, mirroring, creating threads, and assembling components with proper mates.

Main Ideas and Concepts

Objective: Design and assemble a functional car jack in SolidWorks.
Workflow: Start by designing individual parts, then assemble them.
Modeling Techniques Used: Sketching, dimensioning, extruding, mirroring, creating construction geometry, applying cosmetic threads, fillets, and assembly mates.
Assembly: Use mates to position parts correctly and add hardware (bolts and nuts) from the SolidWorks Toolbox.

Detailed Methodology / Instructions

Part 1: Base Part

Select front plane → sketch vertical and connected lines
Assign dimensions: 72 mm, 12 mm, 30 mm, 2.5 mm, 150 mm
Create construction geometry and a circle with 12 mm diameter
Mirror entities about a line
Extrude the sketch to create the base solid
Create a reference plane offset by 30 mm for mirroring the body (merge solids unchecked)
Sketch and extrude a rectangle up to surface on both sides
Save as Part 1

Part 2: Second Component

Select top plane → sketch a straight slot from origin
Assign dimensions: length 200 mm, diameter 25 mm
Draw two circles at ends, diameter 12 mm, make them equal
Extrude boss with thickness 6.5 mm
Save as Part 2

Part 3: Screw Rod

Right plane → sketch circle diameter 50 mm, extrude 50 mm
Front plane → sketch hole circle diameter 12 mm, distance 25 mm from origin, extrude cut mid-plane
Sketch circle diameter 25 mm, extrude boss 500 mm
Add cosmetic thread (metric 24x2) on both ends, enable shaded cosmetic threads
Save as Part 3

Part 4: Puller Part

Top plane → sketch spline straight slot, dimension 70 mm length, 19 mm tip radius
Draw two small circles, diameter 12 mm, make equal
Extrude boss 38 mm
Sketch centerline and circle (diameter 24 mm) on face, extrude cut through hole
Add cosmetic thread (metric 24x2) through hole
Assign color and save as Part 4

Part 5: Another Component

Top plane → sketch horizontal straight slot from origin
Assign dimensions: 50 mm length, 12.5 mm radius
Draw two circles at ends, diameter 12 mm
Extrude boss 38 mm
Sketch vertical centerline and circle (diameter 11 mm) at midpoint
Extrude cut 12.5 mm depth (not through all)
Assign color and save as Part 5

Part 6: Puller (Detailed Sketch & Revolve)

Top plane → sketch centerline and circle (diameter 70 mm)
Draw lines and trim unwanted parts to form profile
Offset entities inside by 3 mm
Extend and trim lines to complete profile
Revolve boss around axis line
Sketch rectangle 11x3 mm, mirror entities, extrude cut mid-plane through all
Circular pattern of cutouts (4 total)
Sketch circle diameter 11 mm, extrude boss up to surface
Apply fillets 1.5 mm inside and outside
Assign green color and save as Part 6

Assembly Process

Create new assembly, insert all six parts
Fix Part 1 in place
Use mate tool to align holes, edges, and surfaces between parts (coincident, concentric, parallel)
Drag and duplicate parts as needed (e.g., multiple instances of Part 4)
Adjust orientation and position to assemble the car jack correctly
Use Toolbox to insert ISO standard bolts and nuts (M12 bolts and nuts)
Position bolts and nuts into holes; SolidWorks automatically fixes them
Final check to ensure parts are properly mated and aligned
Assembly complete with realistic background and perspective settings

Key Lessons

Importance of precise dimensioning and sketching for accurate modeling
Use of construction geometry and mirroring to save time
Creating cosmetic threads for realistic representation of threaded parts
Application of mates in assembly to simulate real-world mechanical connections
Utilizing SolidWorks Toolbox for standard hardware components
Saving parts frequently and organizing workflow part-by-part
