    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 Data including the third-part components are made by the Company.

Application Overview

Purpose

  • Purpose
    • To rotate workpieces on 8-position index table.
  • Operation
    • Retracting the (indexing) cylinder, removes the finger from the groove of the indexing gear.
    • When the (rotation) cylinder is extended, the claw engages the ratchet gear and the index table rotates. The tension springs keeps the claw pressed against the gear.
    • When the (indexing) cylinder is extended, the finger is inserted into the groove to fix the rotational position.

Target workpiece

  • Shape: connector
  • Size: W50 x D50 x H30 mm
  • Weight: 0.15 kg

Design Specifications

Operating Conditions or Design Requirements

  • Movement angle: 45degrees
  • Cylinder stroke: 100mm
  • Stopper stroke: 10mm
  • Outer dimensions: φ600 x H114mm

Selection Criteria for Main Components

  • Selected an air cylinder that has the thrust specification required to rotate the index table 45 degrees in 1 second.

Design Evaluation

Verification of main components

  • Air Cylinder thrust calculation
  • Conditional value: angle θ = 45degrees, movement time t = 1sec., link arm length L = 0.125m, moment of inertia applied to air cylinder I = 0.5492kg·m²
  • As uniform acceleration motion is assumed as angular velocity here, θ: oscillating angle (rad), 45° = 2π/8rad
  • Angular velocity after t seconds: ω = 2·θ/t = 2 x (2 π/8)/1 = 1.571rad/sec
  • Equation of rotary motion: from I·ω = M and M = F·L, cylinder thrust F = I·ω/L = 0.5492 x 1.571/0.125 = 6.9N
  • Theoretical thrust of φ40 air cylinder: 628 (N) when air pressure in use is 0.5MPa
    -> As F = 6.9 (N) ≤ 628 (N), this is acceptable.

Other Design Consideration

  • Ensure the ratchet mechanism has sufficient strength.
    The bending stress needs to be 29 (N/mm²) or less and the shearing stress needs to be 24.7 (N/mm²) or less.
  • Ensure the indexing positioning part is strong enough to apply the required torque.
