    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.

    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 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

  • A device used to inspect surface continuity using a contact probe.

    The unbroken and consistent existence or operation of something over a period of time.

Points for use

  • Manually held by toggle clamp operations.
  • Contact probe is lowered manually.

    Refers to exploratory needles in general in a broad sense. It is a part that contacts or connects to a specimen to measure the properties.

Target workpiece

  • Molded plastic products
    Dims.: W122 x D60 x H20

Design Specifications

Operating Conditions or Design Requirements

  • The toggle clamp operation angle is 90°.
  • External dims.: W230 x D100 x H219

Selection Criteria for Main Components

  • Toggle clamp
    • Maintained type with a horizontal handle is mounted on a 90° incline to save space.
  • Extension spring
    • Spring with a low constant force is selected to ease the operation effort.
  • Linear guide
    • Since the moment load is small, select a guide comparable to the fixture size.

Design Evaluation

Verification of main components

  • Spring constant extension force is low to make operation easier.
  • Extension spring load
    • Formula: Reaction force kx + Initial tension
    • Assumed operation load: F = 10.335N
    • Initial tension: 2.35N
    • Assumed deflection during operation: x = 39.5mm (When set 0mm, when stroked 39.5mm)
    • Moving part weight: 1.1N
    • k＝ (F - Initial tension + moving part weight) / x＝ (10.335 - 2.35 + 1.1) / 39.5 = 0.23
    • Spring constant: k = 0.23N/mm is selected.

Other Design Consideration

  • Linear guide stabilizes linear motion.
  • Select an extension spring with a constant large enough that the probe does not fall down by its own weight.
