Application Overview
Purpose
- A fitting/assembling jig that presses rubber workpieces into aluminum workpieces.
- Fits the convex portion of the rubber workpiece into the concave portion of the other workpiece.
Points for use
- A roller is used to press the parts together.
The fitting load is adjusted by screws.
Target workpiece
- External Dimensions
Workpiece (rubber): W40 x D4.0
Workpiece (aluminum): W41 x D10
Design Specifications
Operating Conditions or Design Requirements
- Outer dimensions: W80 x D60 x H75
- Maximum spring deflection: 8 mm
Required Performance
- The estimate for the required fitting force is 5N, but adjustments can be made if necessary.
Selection Criteria for Main Components
- Screws with dog point
- Screws with dog points and hex nuts are used to compress the springs and adjust the load.
Design Evaluation
Verification of main components
- Springs with the required force are selected.
- Fitting spring load
- Calculation formula: reaction force F = kx
- Number of springs used: 2
- Workpiece fitting load: F = 4.6 N x 2 = 9.2 N
- Assumed deflection during workpiece fitting: x = 4.7 mm (set length: 15.3 mm, free length: 20 mm）
- From k = F/x = 9.2/(4.7 x 2) = 0.98, springs with spring constant: k = 0.98 N/mm are selected.
Other Design Consideration
- Pressing with a roller prevents the load from being applied horizontally.
- Resin sheets are used to enhance the sliding property of the workpiece.
