    CAD Data Limitations

    1. 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.
    2. Unit assembly Data consists of some sub-assemblies.
      It is configured so that each sub-assembly unit can be used as it is or edited.

      3. * The part in the frame is a sub-assembly unit.

    3. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    4. The Data including the third-part components are made by the Company.

  • * Unit assembly Data consists of some sub-assemblies.
       It is configured so that each sub-assembly unit can be used as it is or edited.

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.
