2. Introduction Definition of linkage mechanisms Application in machines Toggle clamp overview

3. Types of Linkage Mechanisms 1. Four-bar linkage 2. Slider crank 3. Pantograph 4. Hooke Joint 5. Watt’s linkage

4. Four-bar & Slider Crank Four-bar: Controls motion with 4 joints Slider crank: Converts linear to rotary motion

5. Pantograph & Hooke Joint Pantograph: Vertical movement using folding supports Hooke Joint: Connects non-coaxial shafts

6. Watt's Linkage Stabilizes rear axle in suspension systems Maintains lateral alignment

7. Kinematics of Linkages Studies motion without forces Includes position, velocity, acceleration

8. Mechanism of Machines Machines convert force and motion Examples: Engines, gearboxes, levers

9. Toggle Mechanism Snap-locking mechanism using linkages Used in clamps for firm hold with minimal force

10. Principle of Toggle Mechanism Over-center lock with pivot points Amplifies input to strong output force

11. Toggle Clamping Process 1. Positioning clamp 2. Applying clamping force 3. Locking over center

12. Force Factors Holding capacity: max safe force Clamping force: actual applied force

13. Clamp Types - 1 1. Vertical hold-down 2. Horizontal hold-down

14. Clamp Types - 2 3. Pull back clamps 4. Plunger-type push/pull 5. Squeeze-action pliers 6. Latch clamps

15. Applications Used in: stone crushers, presses, welding, etc. Provides strong, reliable holding force

16. SolidWorks Simulation Modeled clamp in SolidWorks Motion study verifies design

17. Linkage Model Simulation Animated using linkage software Defined rod lengths and motion constraints

18. Velocity & Acceleration Kinematic calculations validate motion Used to evaluate linkage performance

19. Path of Midpoint Simulated midpoint trajectory Ensures motion accuracy in design

20. Conclusion Toggle clamps offer reliable, amplified clamping Widely used in industrial systems
