Application Overview
Purpose
- Purpose
- To allow for easy clamping of workpiece.
- Operation
- Lift lever arm to clamp workpiece.
- Lower lever arm to release workpiece.
Points for use
- This design is suitable for applications that require low dust generation.
Target workpiece
- Shape: stepped block
- Size: W40xD38xH44mm
Design Specifications
Operating Conditions or Design Requirements
- Clamp angle when fixed：52°
- Outer dimensions: W62xD226xH187mm
Selection Criteria for Main Components
- To reduce the friction coefficient, the same material is employed in the roller follower and the plate cam and Wedge.
Design Evaluation
Verification of main components
- The tightening force during workpiece clamping is verified.
- Tightening force during workpiece clamping
- Conditional value:Wedge tip θ1 = 14°, friction coefficient μ = 0.4, wedge driving force F1 = 3kgf, gravitational acceleration g = 9.8m/s²
- The tightening force during clamping (face pressure on plate cam) F2 is
F2=F1/(2×(μ×cosθ+sinθ)) therefore, F2=3×9.8/(2×(0.8×cos14°+sin14°))=23N
Other Design Consideration
- Wedge mechanism was also designed to lock arm position when clamping workpiece
- The mechanism in this application example operates with a clamping movement from the bottom to the top.
