  • Me new toy.

    I nearly posted this in the thread on indexing but decided it was different enough for it's own post.

    On those motors I do I have to modify the mounting flanges to fit non standard hydraulic pumps, simple job, each of the 4 holes has to be slotted.

    Originally I did them on the CNC but it spends a lot of it's time tied up on more exotic jobs so It did them manually as there aren't that many per month.

    Bolt to the bed of the POS Bridgy using two location dowels in the stator slots, pick the hole up and slot, release the bolt, spin to the next stator slots, fasten, and mill that slot.
    Rinse and repeat two more times, then change the flange.

    Now the quantity is getting bigger, 53 this month so far and 43 advanced orders for July I decided to mount a rotary table on the POS so I only have to bolt it down once.

    Advertised on the Free Home workshop advert site for a 8" or 10" rotary table, got an email of Circlip pointing me to an Ebay auction but by the time I has seen the email the auction had ended, no sweat it was down in south Wales anyway, too far to go.

    So decided to look on ebay and spotted this.



    10" air operated table with 4 positions, so bought it and collected it over the weekend.

    Took the base off to have a look because usually these are 12 or 24 positions and you fit a mask for the number of positions you want.

    Sure enough, 4 position mask fitted over a 24 position ratchet plate.



    In very good condition, hardly looks used,
    So make a quick mounting plate to accept both sizes of flange and go for it.

    Wow Wee, 38 seconds to do 4 slots, more time down the pub now

    Seriously this has really speeded the job up, took details of the 4 position mask and will get the laser cutters to do me a 6 and 8 position one for other jobs that may appear.
    Got it all setup about 11:00 am today, all 53 flanges done, dusted and packed in boxes by 4:15 this afternoon.

    For years (way back in the past)I employed good industry practice and purpose-built fixtures and mechanism for production. Easily repaired with common tools and common sense.

    Nowadays, CNC and other computer-controlled positioners are all the rage. The managers and designers now specify such stuff with no thought given to maintenance or repair - including the skills and knowledge of the poor maintenance man who has to keep the stuff running.

    I witnessed the scrapping (tipped into a dumpster) of a mechanically sound and functional automated coil winder - because the control system was obsolete and ceased to function.

    Good job on the table, Sir John.

          I do something similar.
          Old gearboxes from rewind shop had cover with 8 holes.Newer ones now have only 4. Need to cut 4 and make the others longer....
          thanks

                Few bits of Dexion, Air spindle and a pneumatic ram and you've a dedicated machine. Good that you picked up the second one, hopefully cheaper than the sheep sh***er one.

                Regards Ian.

                  Hey, I just watched the video, what an ugly bastard, first thing this morning I'm going to sack that guy.

                  I mean I have seen ugly bastards before but this guy is abusing the privilege.

                  Paid £103 for it, two gallon of diesel to fetch it but the cruncher was I has to buy Gert a pie and a pint on the way back.

                    Was that as payment for her gear cutting tool idea?

                        John

                        We "used" to use those pneumatic indexers at our firm for rotary table automatic shot blast machines.

                        All I will say is don't ever let any grit get inside !!

                        Looks to be a good solution to your problem though,

                              Just got back from the show, First person I bumped into inside, yep, like a fart in a space suit , His Worship. Had a fondle of the helcal gear (Smartarse).

                              First point of conversation, Have Evan and JT peed on the fence and electrocuted themselves yet?? Noooooooo, it's still rattleing on.

                              At one point, a group of us blocking the aisle, must have been more than three centuries worth of engineering expertise.

                              Show better than ever, makes NAMES look a bit like a garden party. Anyone on the wrong side of the pond, if you decide to have a look at how the mother country does the Homeshop/Muddle Ingineering make sure you come for THIS show.

                              Regards Ian.
