    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.

Application Overview

Purpose

  • Purpose
    • Provide long stroke vertical motion using two stages of linear guides and air cylinders.
  • Operation
    • The two stage design allows for longer stroke.

Target workpiece

  • Shape: box shape workpiece
  • Size: W100 x D80 x H50mm
  • Weight:1kg

Design Specifications

Operating Conditions or Design Requirements

  • Ascending/descending stroke: 100mm
  • Cylinder stroke:50mm
  • Tube inner diameter:φ20mm
  • Cylinder output:126×70%N(Applied pressure 0.4MPa)
  • Outer dimensions:W230×D105×H157(H245 when ascended)mm

Required Performance

  • Running parallelism:15×2=30μm
  • Allowable Load:60N

Selection Criteria for Main Components

  • Air Cylinder
    • Stroke of 50mm or longer and output of 30N or above

Design Evaluation

Verification of main components

  • A cylinder is selected so that the force required for raising the workpiece is obtained.
  • Ascending output
    • Conditional value: target workpiece mass: M1 = 1kg, ascending structure mass: M2 = 2kg, ascending stroke: L = 100mm, gravitational acceleration g = 9.8m/s², air pressure: a = 0.4MPa, cylinder load factor: η = 70% = 0.7
    • Load applied during ascending:W=W1+W2=M1×g+M2×g=1×9.8+2×9.8=9.8+19.6=29.4N
    • Required cylinder thrust:P=W/η=29.4/0.7=42N
      ⇒A cylinder with a cylinder inner diameter of φ12mm or higher is selected.
    • Stroke: L = 100mm, stroke required for each cylinder: L' = L/2 = 100/2 = 50mm
      ⇒A standard cylinder with a stroke of 50mm and an inner diameter is φ20mm is selected.
    • Based on the thrust of a cylinder with a φ20 inner diameter mm: P', the allowable ascending load: W' is verified.
      P'=π/4×20²×0.4=126N
      W'=P'×η-W2=126×0.7-19.6=68.6N
      ⇒Allowable ascending load:W'=68.6N

Other Design Consideration

  • Cylinder tube inner diameter will usually increase with stroke.
    Linear guide must have length equivalent to stroke.
