    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.

Application Overview

Purpose

  • Chuck workpieces while correcting fine displacement.
  • Springs are used to generate the necessary holding force. The claws of the chuck are adjustable to account for positional displacement.

Points for use

  • Low precision workpiece chucking.

Target workpiece

  • Shape: resin pin.
     size: Ø10 x 45mm.
     weight: 0.1kg.

Design Specifications

Operating Conditions or Design Requirements

  • Assumed workpiece displacement amount: ±1.5mm.
  • Spring gripping force: 23.1 to 54.6N.
  • Outer dimensions: W86 x D117.5 x H58mm.

Selection Criteria for Main Components

  • Springs that produce a gripping force of 2kg during chucking are selected.

Design Evaluation

Verification of main components

  • Spring gripping force is verified below.
  • Confirmation of gripping force of chucks.
    • Conditional value: spring constant k = 10.5N/mm.
      Spring free length: L0 = 15mm.
      Minimum spring length caused by maximum displacement amount 1.5mm: L1 = 9.8mm.
      Spring length when displacement amount is 0mm: L2 = 11.4mm.
      Maximum spring length caused by maximum displacement amount 1.5 mm: L3 = 12.8mm.
    • Maximum spring deflection amount caused by maximum displacement amount 1.5mm: X1 = L0 - L1 = 5.2mm.
      Spring deflection amount when displacement amount is 0mm: X2 = 3.6mm.
      Minimum spring deflection amount caused by maximum displacement amount 1.5mm: X3 = L0 - L3 = 2.2mm.
    • Maximum chuck gripping force: F1 = k x X1 = 10.5 x 5.2 = 54.6N.
      Chuck gripping force when there is no workpiece displacement: F2 = k x X2 = 10.5 x 3.6 = 37.8N.
      Minimum chuck gripping force: F3 = k x X3 = 10.5 x 2.2 = 23.1N.

Other Design Consideration

  • The cam shape applies load to the spring during chucking and completely opens the claws from the workpiece during un-chucking.
