    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.

  • * 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

  • Purpose
    • To raise and lower workpieces with minimal abrasion on the guiding shaft's surfaces.
  • Operation
    • A pneumatic cylinder provides the lifting force to raise the workpieces. The vertical movement is guided by two shafts with oil free bushings. Surface abrasion of the shafts is avoided by interconnecting them with a third shaft and a set of gears that interlocks with teeth machined on the two shafts.

Points for use

  • This design is suitable for carrying unbalanced loads.

Target workpiece

  • Shape: tray, pallet
  • Size: W35 x D78 x H36mm
  • Weight: 4.3kg

Design Specifications

Operating Conditions or Design Requirements

  • Ascending/descending stroke: 30mm
  • Outer dimensions: W110 x D350 x H210mm

Required Performance

  • Load + lifting unit: 4.3 + 2.2 = 6.5kg

Selection Criteria for Main Components

  • To raise and lower a workpiece load of approx. 6.5kg, a cylinder with an inner tube diameter of Ø25mm is selected.

Design Evaluation

Verification of main components

  • The cylinder thrust is verified based on the workpiece load.
  • Selection of cylinder
    • Conditional value: workpiece mass W1 = 6.5kg, gravitational acceleration g =9.8m/s²,
      cylinder thrust (pulling side) F1 = 189N (operating pressure 0.5MPa)
    • The load F2 is
      F2 = W1 x g, therefore, F2 = 6.5 x 9.8 = 63.7N < F1
      ⇒There is no problem.

Other Design Consideration

  • Oil free bushings are selected to guide the motion of the shafts and reduce friction.
