IDEA NOTE Simultaneous grip, rotate, and feed operation

A mechanism for gripping, rotating and feeding the supplied workpiece, can be accomplished by a single cylinder.

IDEA NOTE Adopting a urethane pad on the upper part of the clamp

Adoption of a urethane pad increases the friction force at clamping and absorbs variation in workpiece sizes.

    This data is utilized in order to list more useful application examples in the future.

    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.

    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.

Application Overview

Purpose

  • Purpose
    • Feeding the workpiece after rotating 90°.
  • Operation
    • On the output side of the cylinder, the clamped workpiece is unclamped at the first return stroke after the swing arm tumbles hitting the stopper surface and comes to a halt. At the cylinder return side, the arm rises up in an unclamped condition, hits the stopper surface and comes to a halt. When the cylinder moves again toward the output side, the workpiece is clamped at the beginning of the stroke.

Target workpiece

  • Shape: Small-size battery case
  • Size: W22 x L45 x H10mm
  • Weight: 0.03kg

Design Specifications

Operating Conditions or Design Requirements

  • Grips the workpiece after receiving it.
  • Rotation: 90°
  • Work head drop: 100mm

Required Performance

  • Locating accuracy: ±1mm

Selection Criteria for Main Components

  • Cylinder
    • Small-size, double-acting
  • Tension spring
    • Auxiliary part for initially performing the clamp motion/Retaining workpieces during revolution motion .
      Spring constant k = 0.22N/mm
      Spring tensile length l = 11.7mm
      Workpiece retaining force = k x l = 2.57N

Design Evaluation

Verification of main components

  • Verify the cylinder thrust and spring load from the load moment.
  • Check the force to operate the arm.
    • Conditional values: Workpiece mass m = 0.03kg
      Gravitational acceleration = 9.8m/s²
      Cylinder diameter = 16mm
      Supply pressure = 0.5Mpa
      Mechanical efficiency = 80%

      Distance between the tension spring shaft and the rotary shaft at the chuck release: L1 = 10.5mm
      Distance between the tension spring shaft and the rotary shaft after the workpiece is moved: L2 = 28.3mm
      Distance between the tension spring shaft and the rotary shaft at the chuck release: L3 = 38.4mm
      Distance between the cylinder shaft and the rotary shaft after the workpiece is moved: L4 = 17.3mm

      Tension spring natural length L = 80mm
      Initial tension of the tension spring: F1 = 3.73N
      Length of the tension spring at the chuck release: L5 = 114mm
      Length of the tension spring after revolution of the workpiece: L6 = 99mm
      Spring constant k = 0.22N/mm
      Tension of the tension spring at the chuck release: F2 = F1 + k x (L5 - L) = 3.73 + 0.22 x (114 - 80) = 11.2N
      Tension of the tension spring at the chuck release: F3 = F1 + k x (L6 - L) = 3.73 + 0.22 x (99 - 80) = 7.9N
      Cylinder thrust F4 = 101N
      Cylinder thrust F5 = 75N

      Moment ratio.
      In chuck operation/arm revolution.
      Moment generated by the cylinder thrust. From M1 = F4 x L3, M1 = 101 x 38.4 = 3879N・mm
      Moment generated by the spring. From M2 = F2 x L1, M2 = 11.2 x 10.5 = 117.6N・mm

      When the arm is pulled up after revolution of the workpiece.
      Moment generated by the cylinder thrust. From M3 = F5 x L4, M3 = 75 x 17.3 = 1297.5N・mm
      Moment generated by the spring. From M4 = F3 x L2, M4 = 7.9 x 28.3 = 223.6N・mm

      From calculations shown above, we obtain M1 >> M2 and M3 >> M4, which shows that the arm drive operates without delay.

Other Design Consideration

  • Shape of the shoulder pad for locating the main revolution arm.
  • Link shape at the chuck part that fixes the grip release angle and grip close angle.
