Assembly Holding Fixture For Automotive Assembly Stamping Part

Holding fixtures:

- Structural steel tubing is to be used to construct the holding fixture structure.

- Gussets or cross tubing must be incorporated to reinforce the main structure to prevent deflection during loading of the fixture on the CMM machine.

- Structure must have base pads evenly distributed to assure stability and weight distribution.

- Plates must be welded to the structure to accommodate net & clamp details and tooling blocks, etc.

Geometry of Base

Check Fixtures:

- Use “Wolverine” or equivalent style of support when a custom base is required.

- Overall size of base must be shown on fixture drawing.

Base Sizes:

- Base surface must extend 10mm beyond fixture details.

- No details are permitted to extend over the base edge when opened or closed without approval.

- Base length not to exceed 3.5 meters if possible.

Fixture Edge Start Datum's

- Start datums must be square to stated tolerance.

- Start datums must be marked reference only “REF.” with the appropriate bodyline and axis. This does not apply to fixtures with no tooling ball.

- Base surface(s) must be stamped with bodyline reference. (i.e. Z150mm)

-Fixtures under 400mm do not require bodylines in base

-Fixtures over 400mm require minimum 2 bodylines per axis per AQP discretion at design buyoff

Base Flatness and Roughness

- All pads must touch the reference plate surface. No distortion will be allowed.

- All machined surfaces must be between 80 and 100 micro inch finish.

- Machined surfaces of base must be oiled to prevent rusting.
