Application Overview
Purpose
- To press-fit caps into a plastic casing.
Points for use
- Manual operation for small-quantity production.
Target workpiece
- Plastic cap
- Approximate workpiece size: 40X29X12mm
Design Specifications
Operating Conditions or Design Requirements
- External dimensions: W200XD250XH316mm
- Press fit stroke: 30mm
Required Performance
- Pushing force: 50N or more
- Operating load: 10N or less
Selection Criteria for Main Components
- Device mounting stand
- Select an economical shaft with a large diameter.
Design Evaluation
Verification of main components
- Verify that the cap pressing force meets the required operating load.
- Relationship between handle operating load and pushing force
- Conditional values:
Pinion pitch circle radius rm=24mm=0.024m
Operating load Fs N
Pushing force F N = 50N
Pinion center - Operation point R m = 160mm = 0.16m - F N = Fs x R/r
Operating load Fs = F/R × r Thus, Fs ＝ 50/0.16 x 0.024 ＝ 7.5N
⇒Meeting "Necessary operating load of 10N or less."
- Conditional values:
Other Design Consideration
- For most O-ring applications, the groove shapes conform to JIS standards. However, different shapes are used for this application.
