    This data is utilized in order to list more useful application examples in the future.

    Cautions on the CAD data

    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. The CAD data unit assembly consists of sub-assemblies.
      Each sub-assembly unit can be used as it is or can be edited.
    3. * The part in the frame is a sub-assembly unit.

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

Application Overview

Purpose

  • A semi-automatic mechanism that descends the cylinders as the right and left switches are simultaneously pressed and press-fits workpieces together.
  • Pressing either one of the right and left switches does not move the cylinders.
  • A mechanism in which the cylinders stop and ascend when the right or left hand is released while the cylinders are descending.

Points for use

  • The worker would need to press the right and left switches simultaneously to start the machine.
  • Prevents the pinching and entanglement of workers.

Target workpiece

  • Whole workpiece
    • Material: resin case (press-fit process)
  • Cap
    • Dimensions: Ø30 x 6.5mm
    • Mass: approx. 3g
  • Case
    • Dimensions: Ø30 x 26.5mm
    • Mass: approx. 9g

Design Specifications

Operating Conditions or Design Requirements

  • Operational Specifications
    • Maximum cylinder setting stroke: 95mm
  • Outer dimensions
    • W480 x D300 x H353mm

Required Performance

  • Cylinder thrust
    • Cylinder thrust required for press-fitting workpiece: 50N or above

Selection Criteria for Main Components

  • Air cylinder
    • A cylinder with a guide is selected for space-saving purposes.

Design Evaluation

Verification of main components

  • The cylinder thrust is verified to see whether the required press-fitting force is satisfied.
  • Cylinder capacity
    • From setting air pressure: 0.2MPa and cylinder inner diameter: 25mm, cylinder thrust on pushing side: F0 = 63N (from catalog)
    • Required press-fitting force: F1 = 50N * The press-fitting force is checked using measurement instruments before design.
    • Safety factor: F0/F1 = 63/50 = 1.26 * Air pressure is adjusted to 0.2MPa and can be set up to 0.5MPa.
    • When air pressure is 0.5MPa, cylinder thrust on pushing side: F2 = 157N (from catalog)
    • Safety factor: F2/F1 = 157/50 = 3.14
      * The force that breaks the workpiece is 250N or higher.

Other Design Consideration

  • An area sensor is not necessary due to the installation of cover. Access path is limited to the worker side.
