IDEA NOTE Push force is uniform

Two springs are placed in parallel for the workpiece pusher, making the push force uniform over a large surface.

IDEA NOTE High accuracy clamping with linear guides

A linear guide is placed under the workpiece pusher with a toggle clamp on the tip, stabilizing the pusher operation when pushed by the toggle clamp.

    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

  • A fixture that applies a uniform force to hold down a resin tube.
  • This setup is designed for measurement of fluid flow rate through resin tube.

Points for use

  • This setup is vertically mounted and the resin tube is manually secured by toggle clamps.
  • An o-ring is used to prevent fluid leakage .

    Air flow is inhibited by being sealed, and is not affected by changes in atmospheric pressure.

Target workpiece

  • Resin tubing
    External dims.: W70 x D44 x H18
    Weight: 25g

Design Specifications

Operating Conditions or Design Requirements

  • Toggle clamp stroke: 17mm
  • Spring deflection: 7mm
  • External dims.: W220 x D210 x H127 (max.)

Required Performance

  • Workpiece retaining load: 23.5N

Selection Criteria for Main Components

  • Toggle clamp
    • Side push type since horizontal motion is required.
  • Linear guide
    • While the moment load is minimal, select the appropriate miniature linear guide that matches the fixture size.

Design Evaluation

Verification of main components

  • Select a spring capable of retaining the workpiece.
  • Spring load
    • Calculation formula: F = kx
    • Assumed load: F = 23.5N (for 2 springs)
    • Assumed deflection when pressure applied: x = 12mm (When set 5mm (Set length: 20mm, Free length: 25mm), When stroked 7mm)
    • Spring constant: k = 23.5 / 2 / 12 = 0.98N/mm selected

Other Design Consideration

  • Based on the calculated forces required, select a spring stiffness that can reliably clamp the workpiece.
