IDEA NOTE Linear guide in the proximity of chuck claw

Off the shelf grippers can be replaced in a higher load capacity system.

IDEA NOTE Using bolts as end stoppers

Bolt heads are used to prevent the linear guide blocks from falling off the rail.

    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 dimensions of the MISUMI parts in the Data, which can be specifed at 1mm intervals, can be edited under historical data.
    6. The Data including the third-part components are made by the Company.

Application Overview

Purpose

  • To grip/clamp workpiece.
  • Workpiece is gripped/clamped using spring force and released from clamp using external pusher.

    To loosen, disengage clamp (open chuck).

Points for use

  • Link mechanism using compression spring and linear guide.

Target workpiece

  • Cylindrical small-size workpiece/outer dimensions: φ22.5 x H23

Design Specifications

Operating Conditions or Design Requirements

  • Outer dimensions: W95xD160xH100
  • Chuck stroke: 4mm

Required Performance

  • Spring load when releasing: 33N
  • Spring load when clamping: 25N
  • Allowable static moment of linear guide: M A =8.8N・m、M B =9.5N・m

Selection Criteria for Main Components

  • Linear Guides
    • Linear guides that satisfy the allowable static moment are selected.
  • Compression spring
    • A compression spring that can clamp workpieces is selected.

Design Evaluation

Verification of main components

  • A spring that can provide enough force to hold workpieces is selected and the moment of linear guide is verified.
  • Spring force
    • Calculation formula: reaction force F = kx
    • Assumed load when releasing: 33N
    • Assumed load when clamping: 25N
    • Assumed deflection when releasing: x = 16.5mm
    • Assumed deflection when clamping: x = 12.5mm
    • A spring constant: k = 33/16.5 = 2.0N/mm is selected.
  • Moment of linear guide in the proximity of chuck claw
    • <Pitch direction>
      Formula: moment force MA = Fxl2 A =Fxl 2
      Reaction force: F = 33N
      Distance l 2 =45.5mm
      Assumed moment force:M A =33×45.5×10 ⁻³ =1.50N・m
    • <Yaw Direction>
      Formula: moment force M B =Fxl 3
      Reaction force: F = 33N
      Distance l 3 =20mm
      Assumed moment force:M B =33×20×10 ⁻³ =0.66N・m

Other Design Consideration

  • The repeatability of chuck positioning is enhanced due to sliding by the linear guide.
