    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

  • Pick, rotate and lower workpiece to next work station.

Target workpiece

  • Plastic pin with square base
    • Pin DIA.: O15, Length: 100mm
    • Protrusion on one location

Design Specifications

Operating Conditions or Design Requirements

  • W150 x D240 x H377mm
  • Up / down stroke: 150mm
  • Rotation angle: 90deg.

Required Performance

  • Rotational position accuracy: ±1°

Selection Criteria for Main Components

  • A ball spline is used for accurate linear motion as well as for its ability to rotate its orientation.

Design Evaluation

Verification of main components

  • Select a motor that satisfies the torque at required speed.
  • Motor selection
    • Calculation of load torque
      App. condition: Timing belt drive
    • Conditional value:
      D = 57.61 x 10?3m - pulley pitch diameter
      F = 5N - belt tension force
      W = 0kg - workpiece mass
      μ = 0.1 - coefficient of friction, sliding surface
      g = 9.8m/s2 - gravitational acceleration
    • From: Load torque T = D / 2 x (F + μWg) N・m
      T = 1 / 2 x 57.61 x 103 x (5 + 0.1 x 0 x 9.8) = 144 x 10?3N・m
      therefore, we select a motor with larger torque then T = 0.14N・m
    • Torque of the selected motor MAMA012P1A (with continuous operation range up to 5000r/min) is 0.19N・m, and satisfy requirements.
      Motor rated torque > Actually applied torque.

Other Design Consideration

  • For smooth rotation ball spine is supported by ball bearing on two ends and rotation is transmitted thru pulley.
  • If needed install position sensors.
