IDEA NOTE A mechanism that clamps/unclamps workpieces by pushing the cam follower on the side.

A cam follower is mounted on the pushed part of the turntable. When a part enters the turntable, the cam follower hits the side of the received part, unclamping the product.

IDEA NOTE Multiple workpieces can be set.

The vacant space in the turntable is used to house the flat spring. The mechanism has a space-saving structure and is capable of setting multiple work pieces. The current table can be expanded to 8 units.

    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.

Application Overview

Purpose

  • Clamps work pieces using a flat spring.
  • The work piece is held on the turntable using a linking mechanism, and unclamp

    Loosen, release clamp

    ed through the use of a cam follower mounted on the table.

Points for use

  • Rotates the turn table using separate units and stops in the unclamp

    Loosen, release clamp

    ing position. The work piece can then be removed, and operated for the next clamping and rotation.

Target workpiece

  • Material: ABS disc
  • External dimensions: φ16 x 6mm
  • Workpiece mass: 2g

Design Specifications

Operating Conditions or Design Requirements

  • Cylinder stroke: 30mm
  • Deflection of the flat spring at clamp 1.5mm
  • Deflection of the flat spring at unclamp

    Loosen, release clamp

    3mm.
  • External dimensions: W296 x D244 x H237mm

Required Performance

  • Spring load: 1N (with the workpiece clamped)
  • Flat spring material: 304 Stainless Steel

Selection Criteria for Main Components

  • Flat spring
    • Can utilize the available space and meets the clamping load needs.

Design Evaluation

Verification of main components

  • Flat spring
    • Required plate thickness: t
      Plate width: b = 7mm
      Clamp force: P = 1N
      Young's modulus: E = 199GPa
      Load position: l = 37mm
      Deflection at clamp: δ = 1.5mm
      Number of flat springs used: n = 2pieces
      t=((12xP/nxl³)/(3xδxExb))⅓
      =((12x1/2x37³)/(3x1.5x199x10³x7))⅓
      =0.36
      From t > 0.36mm, t is set to be t = 0.4mm.

Other Design Consideration

  • A mechanism that clamps and unclamp

    Loosen, release clamp

    s a work piece from the side. A cam follower is used for the unclamp

    Loosen, release clamp

    ing unclamp

    Loosen, release clamp

    process to achieve a floating condition.
