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. -
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. - The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
- The Data including the third-part components are made by the Company.

It is configured so that each sub-assembly unit can be used as it is or edited.
Application Overview
Purpose
- Purpose
- To position and temporarily grip workpieces α and β at the same time.
- Operation
- When the cylinder makes a pushing movement, the outer chuck connected to the cylinder via a link opens, and the inner chuck connected with a fulcrum opens by a roller at the end of the shaft. When the Cylinder makes a pulling movement, the roller is detached from inner chuck and the workpiece ß is held by spring force and the outer chuck closes to grip workpiece α.
Target workpiece
- Workpiece α
- Shape: rotor
- Size: φ40 x H32mm
- Weight: 0.30kg
- Workpiece β
- Shape: shaft
- Size: φ6 x H62mm
- Weight: 0.04kg
Design Specifications
Operating Conditions or Design Requirements
- Cylinder stroke: 20mm
- Outer dimensions: D120 ｘ W50 ｘ H224mm
Required Performance
- Required accuracy: 0.1mm
- Load on outer chuck: 111.5N
- Load on inner chuck: 9.41N
Selection Criteria for Main Components
- A cylinder is selected using a safety factor of 3.
- As the inner chuck holds a workpiece with a spring force and not cylinder thrust, a spring that can grip workpiece ß is selected.
Design Evaluation
Verification of main components
- The cylinder thrust and spring force are verified based on the required workpiece chucking force.
- Confirmation of workpiece gripping force
- Conditional value: mass of workpiece α M1 = 0.4kg, mass of workpiece β M2 = 0.04kg, gravitational acceleration g = 9.8m/s², cylinder thrust (when pulling, at operating air pressure of 0.4 MPa) F = 118N,
Installation angle of chuck A link θ = 10°, distance from arm fulcrum to power point of chuck A L1 = 30mm, distance from arm fulcrum to acting point of chuck A L2 = 90mm,
distance from arm fulcrum to spring of chuck B R1 = 22mm, distance from arm fulcrum to chucking part of chuck B R2 = 29mm, initial tension of tension spring T = 5.1N, spring constant of tension spring k = 1.86N/mm, deflection amount of tension spring during chuck D = 3mm
Number of arms of chuck A = number of arms of chuck B N = 2 pieces - To chuck workpiece α, the pulling force of the cylinder is used.
The force at the acting point of the link of the chuck A = chucking force of chuck A: Q1 = (F/N)/tanθ x (L1/L2) = (118/2)/tan10 x (30/90) = 334.6 x (30/90) = 111.5N - As the weight of workpiece α = W1 = M1 x g = 0.4 x 9.8 = 3.92N, considering the friction coefficient and number of arms, the workpiece gripping force is (Q1 x N)/W1 = (111.5 x 2)/3.92 = 56.9 times. Therefore, the workpiece can be gripped.
- To chuck workpiece β, the force of tension spring is used.
Force by tension spring: S = T + k x D = 5.1 + 1.86 x 3 = 10.68N - The force at acting point of chuck B link = chucking force of chuck B: Q2 = S x (R1/R2)/N = 10.68 x (22/29)/2 = 4.05N
- As the weight of workpiece β = W2 = M2 x g = 0.04 x 9.8 = 0.39N, considering the friction coefficient and number of arms, the workpiece gripping force is (Q2 x μ x N)/W2 = (4.05 x 2)/0.39 = 20.7 times. Therefore, the workpiece can be gripped.
- Conditional value: mass of workpiece α M1 = 0.4kg, mass of workpiece β M2 = 0.04kg, gravitational acceleration g = 9.8m/s², cylinder thrust (when pulling, at operating air pressure of 0.4 MPa) F = 118N,
Other Design Consideration
- By using a link mechanism, a chucking force greater than the cylinder thrust is produced.
- By using a cylinder, the machining cost is reduced.
