IDEA NOTE Impact Proof Clamping

Unnecessary impact is avoided by using a slide shaft with tapered portions.

IDEA NOTE Clamping position is retained by stopper cam.

In the clamping position, the stopper cam fixes the slide shaft. In this state, the only way to unclamp is to first release the cam by operating the knob.

    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

  • Purpose
    • To clamp workpieces that are vulnerable to impact.
  • Operation
    • Slide shaft mechanism in clamp helps prevent hard impact of the workpiece being clamped.
    • To release the workpiece, first release the knob to disengage the slide shaft, then lift the clamp.

Points for use

  • Manual operation

Target workpiece

  • Shape: glass circuit board
  • Size: W65 x L130 x H0.7mm
  • Weight: 10.6g

Design Specifications

Operating Conditions or Design Requirements

  • Slide shaft stroke: 10mm
    Arm rotation angle: 90°
  • Outer dimensions: W200 x D380 x H144mm

Required Performance

  • Clamping force: 3 to 4N

Selection Criteria for Main Components

  • A spring with a spring constant k = 0.16N/mm that satisfies the workpiece clamping force requirement of 3 to 4N is selected.

Design Evaluation

Verification of main components

  • The clamping force is verified based on the load moment.
  • Confirmation of workpiece clamping force
    • Conditional value: distance between rotary shaft and center of gravity of arm Lg = 87.4mm, angle formed by rotary shaft and center of gravity of arm α = 15.3°, mass of arm M = 436.9g, gravitational acceleration g = 9.8m/s2, distance between rotary shaft and spring post of arm Lk1 = 95.52mm, angle formed by spring post of link base and spring post of arm and rotary shaft β = 20.69°, distance between spring post of link base and spring post of arm Lk2 = 111.4mm, spring constant k = 0.16N/mm, free length of tension spring Lk0 = 100mm, initial tension of spring F1 = 2.94N, number of springs n = 2 pieces, distance between rotary shaft and clamping part La = 201mm, angle formed by rotary shaft and clamping part γ = 3.27°
    • Moment produced by arm mass: Mm = (M x g x cosα) x Lg, hence, Mm = 436.9 x 10?3 x 9.8 x 0.964 x 87.4 = 360.74N・mm
      Moment produced by tension spring: Mk = {k x (Lk2 - Lk0) + F1} x sinβ x Lk1 x n, hence, Mk = {0.16 x (111.4 - 100) + 2.94} x 0.353 x 95.52 x 2 = 321.26N・mm
    • Comparison of moment
      If we put F as the force of the clamping part and Ma as the moment of the clamping part, from Mm + Mk = Ma = F x cosγ x La, F = (Mm + Mk)/(cosγ x La), hence, F = (360.74 + 321.26)/(0.998 x 201) = 3.39N
      -> The clamping force is within the target range (3 to 4N).

Other Design Consideration

  • The shape of the stopper makes it possible to fix the slide shaft during clamping, and it is automatically returned by the coil spring built in the spring plunger during unclamping

    To loosen, disengage a clamp.
