IDEA NOTE Chuck mechanism utilizing gears

By using gears with different numbers of teeth to rotate the chuck, the opening and closing angles between the arms are achieved.

IDEA NOTE Flanged bearings are utilized on the work hand rotary shafts.

By fitting flanged bearings in the through holes without machining the bearing housing with steps, rotary bearing mechanisms that press the shafts from both sides are achieved. To prevent excessive push by the shaft collars, spacers are added on the central inner ring side.

IDEA NOTE Fixation of oil free bushings

Fixation using truss screw reduces cost.

    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]
    To position oddly shaped workpieces and conduct appearance inspection.
  • [Operation]
    In case the opening of the one side of the chuck is restricted, the workpiece can still be held by opening the chuck at different angles.

Target workpiece

  • Shape: cylindrical/resin pin.
     size:Ø14.8 x L132mm. 
     weight: 40g.

Design Specifications

Operating Conditions or Design Requirements

  • Arm angle: arm (large gear): 22.9°.
    Arm (small gear): 38.2 °.
  • Outer dimensions: W270 x D90 x H106mm.

Required Performance

  • Positioning accuracy ±0.1mm

Selection Criteria for Main Components

  • A spur gear with a module: m= 1.0 is selected as it satisfies the requirements for the effective diameter of the large gear Sa=40 and the small gear Sb=24.
  • A cylinder with a gripping force P=24N is selected with a diameter of 20mm.

Design Evaluation

Verification of main components

  • Whether the cylinder thrust produces the required gripping force during chucking is verified below.
  • Confirmation of the gripping force of the whole device
    • Conditional value: cylinder operating pressure = 0.5MPa, output on cylinder push side F = 157N.
    • Effective diameter of large gear connected to cylinder Sa = 40mm.
    • Effective diameter of small gear: Sb = 24mm.
    • Chuck position L: rotation center to 50mm.
    • Efficiency of whole device: η = 0.85.
    • Force of chuck on large gear side: Fa = (F x Sa/2)/L = 62.8N.
    • Force of chuck on small gear side: Fb = (F x Sb/2)/L = 37.68N.
    • As Fa > Fb, Fb is applied to the formula below to calculate the gripping force of the whole device.
    • Gripping force of the whole device P = Fb x η = 32N.

Other Design Consideration

  • The position of work hard can be adjusted using the cylinder joint.
