Application Overview
Purpose
- Fixture to clamp a small-size workpiece while soldering.
Points for use
- Manual mechanism that utilizes a toggle clamp.
Target workpiece
- Circuit board
- External dimension: □ 20 x t 1
- Connector size W8 x D10 x H 2mm
Design Specifications
Operating Conditions or Design Requirements
- Toggle clamp arm open-close angle: 90°
- Spring plunger load: 0.2 - 1.3 N
- External dimensions:
W80ｘD35ｘH47mm
Required Performance
- Workpiece retention load: 0.2 - 1.3N
Selection Criteria for Main Components
- Toggle Clamps
- Application requires a vertical and horizontal handle clamp.
- Since the load is minimal, a normal handle type is used.
- Spring Plungers
- Use the plastic tip part type to prevent scratches to the workpieces.
Design Evaluation
Verification of main components
- Verify required work retention load.
- Plunger load
- Assumed stroke: 2.5mm
- Plunger spring constant
k=1.3/3=0.43N/mm - Based on the values above, the assumed workpiece retention load is given as follows:
F = k x = 0.43 x 2.5 = 1N
Other Design Consideration
- The applied retaining load can be adjusted with the spring plungers.
