Application Overview
Purpose
- Workpiece holding is ensured by 4 point clamping near locating features.
Points for use
- Manually operated toggle clamps.
- Urethane rubber tipped stopper bolts are used to prevent damage to the workpiece.
Target workpiece
- Substate
External dimensions W130 x D110 x t1.6
Design Specifications
Operating Conditions or Design Requirements
- Toggle clamp arm open/close: Angle: 90°
- External dimensions: W300 x D150 x H54
Selection Criteria for Main Components
- Toggle clamp
- Clamp is hold down type with a horizontal handle since the clamping is vertical to restrain the workpiece.
- Wide opening clamps are used to ease workpiece loading and unloading.
- The clamps apply a light force on the workpiece during operation so standard handles are used.
- Stopper bolts with urethane bumpers
- Resin type is selected to prevent workpiece damage.
Design Evaluation
Other Design Consideration
- A dual point contact arm is mounted on the toggle clamp to better utilize one clamp.
- The brackets included with the toggle clamps are used to mount the dual contact arm.
