[family] safety_swivel_load_ring

[sunzhenchuan007]

Family

• Family: safety_swivel_load_ring
• Closes [family-assembly] safety_swivel_load_ring #62
• What the part is: A five-component fixed-pose GN 586 safety swivel load-ring assembly with a U-bent obround clevis, vertical bracket axis, bushing, and bolt.

What changed

• Coupled all geometry and catalog metadata through the five complete GN 586 inch-thread table rows.
• Added independent builders and stable cq.Assembly names for load_ring, bracket, bushing, bolt, and clevis.
• Modeled the user-reviewed clevis from one obround-ended thin strip folded into two parallel ears with coaxial holes.
• Positioned the ring through the clear space between the ears, with its outer bottom at the lower quarter of the total clevis height.
• Easy and medium retain the complete closed ring. Hard starts from the same closed ring and then subtracts a bottom gap exactly k2 / 2 wide.
• Kept WLL, lashing force, tightening torque, temperature range, and swivel-envelope dimensions as metadata only; no load certification or numeric motion angle is claimed.
• Labeled all undimensioned construction choices as proportion.

Previews

Easy / medium / hard

Minimum and maximum extremes

Components, assembly overview, and sequential highlights

preview_parts.png first gives four standard views of every distinct component,
then the complete assembly overview. Its final five rows retain the full
assembly and highlight load_ring, bracket, bushing, bolt, and clevis
one at a time in stable component order.

Checklist

• uv run bench2 validate safety_swivel_load_ring passes locally; easy, medium, and hard each passed 4/4 sampled seeds.
• I ran uv run bench2 preview safety_swivel_load_ring and inspected all formal renders plus the assembly preview_parts.png.
• Multi-body declaration is consistent: family.json declares five solids and five one-off components matching the stable Assembly child names.
• Every PARAM_SPEC.source and every check() constraint cites the GN 586 source or honestly says proportion; nothing is presented as an invented standard dimension.
• The PR touches only designs/safety_swivel_load_ring/ and contains only CI-whitelisted package files; no PDF, research attachment, tmp/, cache, or CQ-editor helper script is included.
• Commits c077b8e, b19fd25, and 50abd54 are DCO-signed.
• AI-assisted: I reviewed the generated geometry and constraints, including the final CQ-editor placement and component-by-component assembly highlights, and stand behind this contribution.

Sources used

• JW Winco GN 586 official product page linked from Issue [family-assembly] safety_swivel_load_ring #62.
• JW Winco GN 586 official 586.pdf and the issue's official table/image attachments.
• The five printed inch-thread catalog rows are preserved as indivisible row selections.

Verification

• bench2 validate: PASS, five non-degenerate solids per instance, all five catalog rows covered.
• bench2 preview: easy/medium/hard, four benchmark views, and min/max renders generated and inspected.
• Ruff: passed for part.py and spec.py.
• Fixed-assembly audit: 20 combinations (five catalog rows × two RFID states × two ring-gap states), zero pairwise volumetric intersections and exact lower-quarter ring placement.
• Local reproduction of the family-pr-checks package whitelist found zero violations.
• preview_parts.png preserves all five independent component views, the complete assembly overview, and sequential highlights of all five stable components.

[github-actions]

Welcome, and thanks for the family PR! Three things that answer most questions:

• No checks running? A maintainer must click Approve workflows once for your first PR — pending, not ignored.
• Red gate? The message tells you the fix: click Details, or read the bench2 validate report comment posted after each run. Reproduce locally with uv sync && uv run bench2 validate <family> (debug help).
• Scope: designs/<family>/ holds only the package files (reference drawings/photos go in the family issue), and the PR checklist must be fully ticked. Not done yet? Mark the PR as a Draft.

safety_swivel_load_ring

  ✓ family.json: keys + base_plane valid
  ✓ pieces: build(16 params) + PARAM_SPEC + check present
  ✓ PARAM_SPEC: 21 params, all entries complete
  ✓ easy: 4/4 seeds sample+check+build+execute clean
  ✓ medium: 4/4 seeds sample+check+build+execute clean
  ✓ hard: 4/4 seeds sample+check+build+execute clean
  ✓ coverage: catalog_row reaches all 5 declared values (standard table fully covered)
  ✓ difficulty separation: difficulties produce distinct programs
  ✓ geometry novelty: 7/12 unique shapes (42% duplicate)
  ✓ solids: every instance non-degenerate, 5 solid(s) each (declares solids=5)
PASS — designs/safety_swivel_load_ring
