Background
The OSE Quick Attach will be used to implement a wide range of attachments for the OSE skid steer. The design considerations were:
1. Use existing OSE parts (4"x4" box tube, 1/2" plate, 1" bolts, etc).
2. Minimize welds, main attachment method bolting.
3. Modular so the spacing can be changed according to attachment.
4. Conforms to SAE-J2513 standard.
SAE standard: File:Sae j2513.pdf
See LifeTrac_Bobcat_Standard and Quick_Attach_Plate_Standard for background on geometry and discussion of ASTM specification of the geometry.
Justin Log by Justin Downs takes it from here.
Product
V1
hashed out different design options, made original DXF file.
The drawing shows a reference for multiple designs, the DXF file has the dimensional layout (select layers accordingly, when they are all on it is cluttered).
For the next step it would be good to talk with whomever will fabricate it to lock in the most efficient build based on available parts, especially for the catch mechanism.
Basic layout for quick attach skid steer mech:
V2
Added in more dimensional work for attachment spacing to skid steer, finished latching mechanism.
Latch mech: The latching mechanism KISSes by utilizing a 5/8" threaded rod that attaches to a 1/2" plate with weld nuts. The plate moves the latch rod to connect and disconnect, this gets rid of any spring or lever which could jam or release during use.
All parts are standard McMaster.
Overview of updated mech:
DXF has true dimensions except for 48" spacing of skidsteer plates.
Sketchup
Sketch up file:
DXF of Critical COmponent
Notes
General notes:
V1
Good work, needs specifics of actual skid steer. Needs discussion with Justin.
V2
Ready to build first prototype. Final fit up will be determined after build.
TO DO
To be done:
V1
1. Finalize dimensions on actual skid steer, spacing, fit up etc.. With consideration to the bobcat spacing.
2. Finish catch mechanism based on available parts (some ideas are in the attached drawing).
V2
1.Finalize dimensions on actual skid steer, spacing, fit up etc.. With consideration to the bobcat spacing.
2.Work more on Sketch up file?
