    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.

  • * Unit assembly CAD data consists of some sub-assemblies.
       Each sub-assembly unit can be used as it is or can be edited.

Application Overview

Purpose

  • A manually indexed rotary table using a ball plunger and ball buttons.
  • Used for inspecting specific locations on a component with microscope.

Target workpiece

  • Plastic case
    Case dimensions: Ø110 H20

Design Specifications

Operating Conditions or Design Requirements

  • External dims.: W100 x L170 x H129
  • Table O.D.: 120

Required Performance

  • Retaining force that withstands 10N of external force applied.

Selection Criteria for Main Components

  • For ease of adjustment, Long Ball Plunger is used in this application.

Design Evaluation

Verification of main components

  • Select a ball plunger capable of retaining a workpiece.
  • Ball plunger retention force calculations
    • V groove angle of the ball button is 45 degrees per side, and plunger setting load and operation force are the same.
      The retaining force with plunger setup for 0.078mm stroke (almost zero touch) is
      0.99N + 6.9N = 7.9N
    • Max. force to overcome the V groove is at the plunger stroke 0.75mm,
      9.525N + 6.9N = 16.425N
    • Distance from ball button groove edge to the rotation center is approx. 53mm,so the torque that it takes to overcome the V groove is approx. 16.425 x 0.053 = 0.87N・m (Actually a little more due to friction)
      When an external force 1.0kg (10N) applies to the center of handle (80mm from the center of rotation), the torque is 0.8N・m
      ⇒ BPJL8 where the retention force covers the load value is selected.

Other Design Consideration

  • A bearing holder is used to retain rotation.
