IDEA NOTE The workpiece is always clamped by the spring. In the discharge of a charged workpiece, it is unclamped by a pusher

The workpiece being clamped by the spring is unclamped as the cylinder presses the pusher against the hinge block to incline the hinge to the center.

    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.

    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

  • A cylinder employing an automatic mechanism unclamps the workpiece as the pusher mounted on the cylinder presses against the hinge block..
  • Clamps the workpiece via the tension springs attached to the work holder.

Points for use

  • The workpiece is suctioned and transferred to the charging/discharging position by another unit.

Target workpiece

  • Workpiece: resin case
    Material:ABS
    outer dimensions:66 x 27 x 15

Design Specifications

Operating Conditions or Design Requirements

  • Cylinder Stroke: 43mm
  • Deflection of tension spring: 5mm
  • Outer dimensions: W240 x D240 x H266 (overall dimensions)

Required Performance

  • Cylinder thrust of 21N or higher
    (Following the calculation process, a cylinder with a cylinder thrust with a safety factor 1.5 times the spring force was selected.)
  • Required clamping force: 10N

Selection criteria for Main Components

  • Cylinder
    • Stroke adjustment is easy and load requirement is satisfied.

Design Evaluation

Verification of main components

  • A spring with the required clamping force was selected, and the cylinder for unclamping was selected according to the spring force.
  • Load of tension spring
    • Required clamping load: FA = 10N
    • Spring deflection during clamping: x = 11mm
    • Number of used springs: n = 2 pieces
    • Spring initial tension: f = 1.67N
    • FA = n (kx + f)
    • From k = (FA / n - f) / x = (10 / 2 - 1.67) / 11 = 0.30,
    • Spring constant: k = 0.32N/mm was selected.
  • Cylinder thrust
    • Spring force during unclamping: FB
    • Spring deflection during unclamping: d = 16mm
    • FB = n (kd + f)
    • = 2 x (0.32 x 16 + 1.67)= 13.58N
    • If safety factor is set to 1.5, 13.58 x 1.5 ≈ 20.37N.
    • When cylinder thrust P > FB, the specification is satisfied.

Other Design Consideration

  • As the workpiece needs to be held while it is transferred by a turn table (another unit), the mechanism keeps clamping the workpiece using a spring.
  • The pusher (cylinder) stands by at the unclamp position and the turn table (another unit) transfers the workpiece to the unclamp position.
