    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.

    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.

Application Overview

Purpose

  • Automated pusher mechanism for grip and release of molded plastic workpieces.

Points for use

  • Workpiece is gripped by jaws placed inside its bore diameter, roughly guided on its outer diameter, and is internally secured by a spring.
  • To release workpiece i.e. gripper jaws, external force is applied.

Target workpiece

  • Molded plastic product
    Dims.: Ø67 x H30mm
    Weight: 50g

Design Specifications

Operating Conditions or Design Requirements

  • External dims.: W190 x D100 x H66
  • Push stroke when clamped: 14mm
  • Single axis robot stroke: 800mm

Required Performance

  • Workpiece retaining load: 2.61N
  • Max. operating force when released: 6.67N

Selection Criteria for Main Components

  • Compression spring
    • Select a spring with a constant that does not apply excessive load on workpiece, as well as keeping the operation efforts low.
  • Linear guide
    • Since little moment loads apply, select an optimum guide relative to the fixture size.

Design Evaluation

Verification of main components

  • Verify retaining load during clamping and the pusher force when releasing.
  • Compression spring load
      • Reaction force F = kx
      • Workpiece retaining load: 2.61N
      • Assumed deflection when retaining workpiece: x = 9mm
      • From k = F / x = 2.61 / 9 = 0.29, spring constant k = 0.29N/mm is selected.

    • Assumed deflection when unchucked: x = 23mm (when workpiece retained 9mm (set length:36mm, free length: 45mm), when unchucked 14mm)
    • Spring load when unchucked: F = kx = 0.29 x 23 = 6.67N
    • Applied pressure by the pusher is 6.67N or more.
