19-0/1 Integration Tooling

Integration sequence:

Loaded Modules on Rings
- Welding, QC testing
Load Services into ¼-shell
- Transfer ¼-shell to integration tooling
Load Rings into ¼-shell
- Transfer Rings to integration tooling
- Integrate Rings into ¼-shell
- Welding, QC testing
Integrate two ¼-shells
- QC testing
Package, ship

19-0 1/4-shells in B33 cleanroom:

Next steps:

Selection of a linear rail and bearing to test for 19-0/1.

Requirements (preliminary):

Cleanroom compatible
Load: operator handling loads
- weight of loaded Ring and HF (~1kg, not in SE)
- operator load - handling/sliding linear rail
  - installing HF onto rail fixture while extended - robust to operator error
Range: ~0.4m (retracted) to ~0.9m (extended)
- extend by at least 0.5m (to make ring engage far side 1/4-shell)
- retracted length ~0.4m (to not overhang edge of table)
Precision:
- Line up threaded holes in Ring with thru holes in 1/4-shell
  - 2mm pins, 2.4mm clearance holes → ~0.4mm dia. clearance shared between assembly and manufacturing tolerances
  - 19-0/1 prototype: linear rail, HF bolted on. no other adjustment. unbolt/rebolt to make small adjustments via oversized holes
    - Bolt together, slide in rail, check misalignment, slide out rail, adjust if required
    - Bolt together, install taper pins, slide in rail, install fasteners
Usability:
- include handle
- include lock in "extended" position
- keep clear of fragile parts - work with covers etc.
Travel needed:
- ~500mm to bring one side into contact with other side
  - preserving space on table for welding/covers/etc on both sides of HF
- ~160mm to move one HF beyond edge of 1/4-shell

- Prototype 19-0/1 concept (following what was shown previously): ~500mm travel, ~400mm length
  - 2x McMaster # 8379K6 , stacked

- Alternative: 1x ~250mm travel, ~400mm length rail per ring, to move both 1/4-shells and meet in the middle
  - not preferred: less assembly flexibility, less clearance when connecting handling frame due to less travel
- Alternative: 1x ~450mm travel, move rails to edge of table so single rail can reach far side 1/4-shell
  - not sure about rigidity cantilevered from bearing at one end, or about table space to enclose.

Candidate vendor parts:

8020 Inc. # 6516
- slide on 1.5" t-slot rail. add #6800 locking handle. not preferred due to sliding friction and height.

6516

Misumi # SSE2BWLZ14G-400
- linear rail w/ bearings, stainless steel, cleanroom grease.

- locking mechanism?
  - Misumi SECWK14 compatible with above, but not stainless

- - also end stop bolts
  - Grease not preferred (cleanliness / accidental spread)
