Application Overview
Purpose
- The roller is positioned using V blocks and urethane molded bearings.
Points for use
- The upper fixture with urethane molded bearings is held with toggle clamps to prevent the roller from moving in vertical direction.
- Runout is measured with a contacting displacement sensor.
Target workpiece
- Roller
- Outer demensions: φ20xL120
- Workpiece weight: 150g
Design Specifications
Operating Conditions or Design Requirements
- Toggle clamp arm open/close angle: 90°
- External dimensions:
W150ｘD150ｘH107
Required Performance
- Runout measurement accuracy: 0.01mm increment
Selection Criteria for Main Components
- Toggle clamp
- Hold Down type is chosen since the roller is held with V blocks
- Linear guide
- Selected based on the unit size since the applicable moment loads are not very large.
Design Evaluation
Other Design Consideration
- The roller is centered with the V blocks and urethane molded bearings (3 point contact)
- The roller can be measured at arbitrary position within the linear guide motion range.
- The measurement sensor is fixed with a locating pin and a screw to prevent movement during measurements.
