IDEA NOTE Simplified Height Adjustment

By using keys with the bracket, you can reduce the time required to make height adjustments.

IDEA NOTE Cylinder-Mounting Bracket Design

Because of the design constraints, the support structure is created by using two angled brackets.

IDEA NOTE Use a flat spring as a buffer.

Use a flat spring to create a buffer for the pusher (instead of using two guides and a spring).

    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.

    4. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    5. The dimensions of the MISUMI parts in the Data, which can be specifed at 1mm intervals, can be edited under historical data.
    6. The Data including the third-part components are made by the Company.

Application Overview

Purpose

  • Simple workpiece pusher using a thin flat spring.

Target workpiece

  • Shape: Rectangular resin object
  • Size: W76 x D36 x H41mm
  • Weight: 50g

Design Specifications

Operating Conditions or Design Requirements

  • Outer dimensions: W155 x D247 x H251mm, cylinder stroke: 120mm

Required Performance

  • Workpiece stopping accuracy: 0.5mm

Selection Criteria for Main Components

  • Spring
    • Selection based on the workpiece weight, friction resistance, and the cylinder speed.

Design Evaluation

Verification of main components

  • Ensure the flat spring has an appropriate spring load.
  • Workpiece
    • Mass: 50g
    • Friction coefficient: 0.2
    • 50×0.2=10g
  • Cylinder speed
    • Adjusted by speed controller (commonly 100mm/s).
  • Calculation of approximate spring load
    • δ=0.2mm
    • b=50mm
    • h=0.5mm
    • E=216×10³ N/m²
    • l=26mm
    • P=δ×b×h³×E/(4×l³)
      =0.2×50×0.5³×216×10³/(4×26³)
      =3.84N
      * Use the calculated spring load as a guide. Verify the actual spring load through trial and error.

Other Design Consideration

  • Consider using absorbers to prevent stoppages that are caused by shocks.
