Cautions on the CAD data
-
Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
You will need to edit the Data so that it meets your specific design conditions. -
The CAD data unit assembly consists of sub-assemblies.
Each sub-assembly unit can be used as it is or can be edited. - The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
- The Data including the third-part components are made by the Company.
* The part in the frame is a sub-assembly unit.

Application Overview
Purpose
- The toggle clamp can be pulled back to allow an insertion of the workpiece.
- After the component is set in place, the head of the clamp will apply an increased force on the component at the end of the stroke.
Points for use
- Sliding toggle clamp creates a space for easy workpiece setup.
Target workpiece
- Plastic case
External dims.: W40 x D40 x H30
Weight: 50g
Design Specifications
Operating Conditions or Design Requirements
- Toggle clamp arm open/close angle: 90°
- External dims.: W100 x D150 x H150
Required Performance
- Assumed press fit load on workpiece: 20N or less (I.D. Ø15mm, Fitting width 3mm)
- Periodically check for cracks in the clamps due to loads exceeding 20N.
Selection Criteria for Main Components
- Toggle clamp
- Vertical handle for vertical load application.
- Fulcrum pin
- A fulcrum pin is selected to allow the toggle clamp to slide without extra clearance.
Design Evaluation
Verification of main components
- Verify whether the toggle clamp can generate the press fit load.
- Assumed press fit load: 20N
- Clamping force at the end of toggle clamp stroke: 392N
- 20N < 392N is OK
Other Design Consideration
- Simplified press fitting is performed by a toggle clamp.
- Smooth sliding facilitated by fulcrum pins.
- Not suitable when load management is needed.
- With rubber feet, easy to move the part where needed, and the non-conductive rubber ensures sound operation where static electricity is of concern.
