Application Overview
Purpose
- Cylindrical workpieces are fed at a fixed rate.
- This operation has both stationary and moving saw tooth blade. The moving saw tooth blades transport workpieces at a fixed rate and interval.
Target workpiece
- Shape: Aluminum rollers
- Size: O.D. φ20 x I.D. φ18 x L200mm
- Weight: 33 g
Design Specifications
Operating Conditions or Design Requirements
- Up /down stroke: 30mm
- Elevating thrust: 220N
- Cycle time: 30sec
- External dims.: W213 x D430 x H140mm
Required Performance
- Positioning accuracy: ±0.2mm
- Load weight: 22kg
Selection Criteria for Main Components
- Electric cylinder
- Electric cylinder is used when an air source is not available.
- Space saving
- The plate cam stroke only needs to be 30mm to achieve a 100mm up and down stroke.
Design Evaluation
Verification of main components
- Verify the electric cylinder thrust for the ability to raise the moving object.
- Lifting thrust calculation
- Conditional value: Moving object mass M = 22kg, Gravitational acceleration g = 9.8m/s², Plate cam angle D = 21°
Electric cylinder thrust (Max.) F = 156N
Force applicable in vertical direction: W = M x g = 22 x 9.8 = 216N
Horizontal thrust required to raise W in vertical direction: P = W x tan(D), then
P=W×tan(D)=216×tan21°=83N
Since horizontal thrust: P = 83N < Electric cylinder thrust (max.) F = 156N,
sufficient elevation force can be obtained.
the max. elevating force would be W(max) = F / tan(D) = 156 / tan21° = 406N
- Conditional value: Moving object mass M = 22kg, Gravitational acceleration g = 9.8m/s², Plate cam angle D = 21°
Other Design Consideration
- The linear guide blocks are stationary with moving rails to move the cam.
- Alum. extrusions are as a low weight option.
- Electric cylinder is used for installation in locations without air source.
