Application Overview
Purpose
- A device used to inspect surface continuity using a contact probe.
Points for use
- Manually held by toggle clamp operations.
- Contact probe is lowered manually.
Target workpiece
- Molded plastic products
Dims.: W122 x D60 x H20
Design Specifications
Operating Conditions or Design Requirements
- The toggle clamp operation angle is 90°.
- External dims.: W230 x D100 x H219
Selection Criteria for Main Components
- Toggle clamp
- Maintained type with a horizontal handle is mounted on a 90° incline to save space.
- Extension spring
- Spring with a low constant force is selected to ease the operation effort.
- Linear guide
- Since the moment load is small, select a guide comparable to the fixture size.
Design Evaluation
Verification of main components
- Spring constant extension force is low to make operation easier.
- Extension spring load
- Formula: Reaction force kx + Initial tension
- Assumed operation load: F = 10.335N
- Initial tension: 2.35N
- Assumed deflection during operation: x = 39.5mm (When set 0mm, when stroked 39.5mm)
- Moving part weight: 1.1N
- k＝ (F - Initial tension + moving part weight) / x＝ (10.335 - 2.35 + 1.1) / 39.5 = 0.23
- Spring constant: k = 0.23N/mm is selected.
Other Design Consideration
- Linear guide stabilizes linear motion.
- Select an extension spring with a constant large enough that the probe does not fall down by its own weight.
