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

Past presentation: Integration Tooling and Plan at SLAC 8 Nov 2021.pptx

Next steps:

• Prepare for 19-0 (Drafting - setup with dummy rings and linear slide)
• Finalize design/drawings of tables

Linear Rail

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.

• 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)

• Igus Drylin NT

• • plastic slides
  • Sent request to Igus contact

  • Looking for:

    • ~500mm linear motion
    • ~400mm collapsed length
    • ~10lb load capacity
    • Low duty cycle (moved occasionally)
    • End stops at both ends of travel
    • For clean assembly room (ISO7) use
    • Qty ~12 of these slides
