IDEA NOTE  Uses a rotary actuator as a drive source.

The reason for the employment of a rotary actuator is that space-saving is required due to a restriction on the upward stroke and the movement needs to be slow.

IDEA NOTE Prevention of oil splash

The actuator and other parts are located below the workpiece transfer face.
A cover is installed around the thrust bearing.

IDEA NOTE Absorbs misalignment between shafts.

As a measure against misalignment between the rotary actuator shaft and the lead screw shaft,
only a thrust bearing is installed, without installing a radial bearing or an angular contact bearing.
A double disc type coupling is employed.

    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 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
    • Jack for switching mold type.
  • Operation
    • Rotary movement is converted into linear movement. By rotating the rotary actuator by 180°, the lead screw is rotated. The nut on the lead screw makes linear movements to move up and down.

Points for use

  • A heavy load is slowly raised a short distance. A rotary actuator is used as the drive source.

Target workpiece

  • Mold for lead frame
  • Size: W180 x D310 x H214mm
  • Weight: 34kg

Design Specifications

Operating Conditions or Design Requirements

  • Ascending/descending stroke: 2.5mm
  • Safety factor: S = 1.7
  • Outer dimensions: W180 x D400 x H262mm

Required Performance

  • Positioning accuracy: ±0.05mm
  • Upward thrust: 580N

Selection Criteria for Main Components

  • Lead Screw
    • As the ascending/descending stroke is 2.5 mm, a 5-mm lead is selected as its multiple number lead.
  • Rotary actuator
    • A rotary actuator with an oscillation angle of 180° and a torque of 1.7 [N・m] (0.5 MPa) or higher is selected.

Design Evaluation

Verification of main components

  • Whether an appropriate thrust for raising the workpiece can be obtained is verified based on the specifications of the rotary actuator and the lead screw.
  • Calculation of upward thrust
    • Conditional value: workpiece mass W = 55kg, gravitational acceleration g = 9.8m/s², friction coefficient μ = 0.21, lead of lead screw R = 5mm, lead angle d = 4°40' = 4.67°, rotary actuator torque T = 1.863N・m = 186.3N・cm
      Screw efficiency: η = (1 - μ x tan(d))/(1 + μ/tan(d))
      = (1 - 0.21 x tan4.67°)/(1 + 0.21/tan4.67°)
      = 0.275
      Upward thrust F = (2π x η x T)/R
      = (2π x 0.275 x 186.3)/0.5
      = 644N
