IDEA NOTE Rotation of index table and rotation of work holder are synchronized.

As the index table rotation angle is 90 degrees and the rotation angle of the work holder is 90 degrees, the number of teeth on the fixed gear and that on the moving gear are the same. Gears with a module of 0.5 and 80 teeth are selected.

IDEA NOTE Ensure work holders rotate without backlash.

Use non-backlash gears.

    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.

    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.

  • * 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.

Application Overview

Purpose

  • Purpose
    • Inspects workpieces that are placed on the index table at three different locations.
  • Operation
    • As the index table rotates clockwise 90 degrees to the next inspection position, the work piece holders simultaneously rotate 90 degrees counterclockwise.

Target workpiece

  • Shape: circuit board.
  • Size: W80 x D80 x H12 mm
  • Weight: 40 g

Design Specifications

Operating Conditions or Design Requirements

  • Rotation angle: 90 degrees, 4 positions
  • Outer dimensions: W390 x D480 x H217 mm

Required Performance

  • Positioning accuracy: ±0.1 degree
  • Load weight: approx. 8.7 kg

Selection Criteria for Main Components

  • For this application, we will select a safety factor of 3. Therefore, the index table must have an allowable thrust load of 226N (or higher) and an allowable moment of inertia of 0.15kg·m2 (or higher).

Design Evaluation

Verification of main components

  • The thrust load and moment of inertia of the index table are verified based on the workpiece weight and moment of inertia.
  • Thrust load and moment of inertia of index table
    • Conditional value: mass of workpiece: W = 8.7 kg, gravitational acceleration: g = 9.8 m/s², safety factor: S = 3, allowable moment of inertia of index table: 0.17 kg·m²
    • For the workpiece mass of 8.7 kg, the thrust load when considering the safety factor is F = 3 x 8.7 x 9.8 = 226 N, which is smaller than the allowable thrust load (800 N) of the selected index table. Therefore, the safety factor is verified.
    • From the moment of inertia of workpiece: M = 0.050 [kg·m²], the moment of inertia when considering the safety factor (S = 3) is M1 = 3 x 0.05 = 0.15 kg·m², which is smaller than the allowable moment (0.17kg·m²) of inertia of the selected index table. Therefore, the safety factor is verified.

Other Design Consideration

  • A shaft and collar is used to affix the index table.
