IDEA NOTE The load cell is moved up and down by a cam.

The cam causes the load cell to stroke 1.5mm. As the load is applied to the bearing of the cam shaft, the load is not applied to the vertical movement mechanism.

    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 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

  • To measure load that is applied to the bushing when press fitted into the nylon gear.
  • The measurement rod extends to the transfer surface via a cam mechanism during load measurement.

Points for use

  • There is no protrusion on the transfer line.

Target workpiece

  • Bushing
    Size: φ100mm, weight 10N

Design Specifications

Operating Conditions or Design Requirements

  • Vertical stroke: 1.5mm
  • Outer dimensions: W314 x D115 x H226mm

Required Performance

  • Load: lift part = 7N

Selection Criteria for Main Components

  • In order to lift a load of 7N (for a maximum lift height of 1.5mm) with a cam having a radius of 30mm, a motor with a torque of 0.25Nm or higher is selected.

Design Evaluation

Verification of main components

  • The load torque is verified based on the workpiece load.
    • Calculation of load torque: radius 30mm, load 7N, T = 0.03 x 7 = 0.21N·m

Other Design Consideration

  • By installing the whole unit below the transfer surface, space can be saved.
  • A ball spline can be used as both a vertical guide and cam follower rotation stopper.
  • The load is conveyed via the rod in the loose hole to the load cell, which is placed on the spline.
