Suggestions Wanted: Stamp Control of a Drill

ArchiverArchiver Posts: 46,084
edited 2003-12-12 18:28 in General Discussion
Hi Everyone!

Built a gadget that I use a lot. It is essentially a linear
actuator. It is about 70 inches long.

It parts include: a long bolt, a nut attached to a carriage and a
drill to turn the bolt.

The drill turns the bolt which moves the carriage to the desired
position. It is currently a manual process. I wish to automate it
with a Stamp.

The drill is just a heavy duty a/c drill. It is a little beafier
than what most guys would have in their garage. A smaller one could
be used.

Would like suggestions on how to handle the switches for the drill.
Should I hack the drill? Or, put components on the outside to
manipulate the current switches.

Or, should I forget the drill and go directly to an A/C or DC motor?
The nice thing about the drill is that it is trivial to connect to
the 3/8" bolt.

I have tried an inexpensive ceiling fan motor. It just didn't have
the power or speed that I needed.

Your thoughts please.

Thanks!

Take care,
Frank

    Mount your gear TO the drill and you can always dismantle it to get use of
    just the drill.

    I like the idea of a motor (stepper for location?) tied to the
    stamp....might seem a bit better.

    Hi Frank,
    You need to give more information on your gadget. Do yo u need to stop it at
    a certain position, or just go to the end and stop?

    Do you need to vary the travel speed or just let it rip wide open?

    If you are using this to open a window or door, then turn on the drill with a
    solid state relay, or mechanical relay and drive it until the nut trips a
    limit switch. You may need another relay to reverse the drill to close the door.

    Tell us more about what you want to do.

    If I have understood you right you are rotating the bolt so that the
    nut slides up and down. If you are looking for accurate control I
    would suggest you grab hold of a stepper motor and attach the bolt
    to it. You can go about this several ways the most ideal would be
    drilling a small hole in the base of the bolt to accomodate the
    motor shaft, a small screw can be used to secure it, but to do this
    you will have to be precise in your drilling. Anyway back to the
    main idea, attach a stepper motor to the shaft depending on the
    specs you can get away with using a ULN2003 to drive it or if you
    need more power try something like the L293D or L298 to drive it.
    Alternatively you can adopt a feedback system to sense the position.
    One such way of doing this is to have a small wheel with slits in
    it. Using a photo-interrupter you can sense how much the shaft has
    turned since each slit in the wheel corresponds to a certain amount
    of travel. For this you may want to adopt a geared AC or DC motor
    depending on your preference.

    Im not sure if I have been clear enough but let me know I can
    probably draw up a diagram on how you would go about doing this.

    Some cheap motors are availible from oatleyelectronics
    http://www.oatleyelectronics.com/motors.html
    (No Its not my shop and Its only a suggestion!)

    The M30 AC MOTOR may suit your purpose if you dont need speed.

    Frank,

    One way would be to use a relay. You could wire it to the plug, and leave
    the stock switch in place, just tape it down. If the drill is never to be
    used as a drill again, I would go ahead and remove the switch and again use
    a relay to turn it on and off.

    As to other motors, All Electronics usually has a good assortment of gear
    motors. As you say though, you will need to couple it to the 3/8" bolt. If
    the drill works for you, I would stick with it. If it is too big, or
    otherwise less than ideal, a gear motor is pretty easy to couple to a 3/8"
    bolt. I use a drill to wind Tesla coils with, for the same reason as you do,
    it is easy to attach and I use it for other things most the time.

    I would hack the drill myself<G>.

    As far as easy connections, you can get chucks cheaply (relatively) from MSC
    or probably McMaster Carr.

    Note: As I remember it, a drill is a universal ac dc motor. So, if you
    were to rectify the ac and feed the motor with dc of different polarities to
    make it work. You could use relays on the output of the bs2 for this. Then
    you wouldn't have to hack the drill. Folks, correct me if they have
    something new that I don't know about. I want to know<G>!
    I have used drills in stationary applications before. Hose clamped
    them to a table top or milk crate<G>.

    I would just use a transistor on the output of a stamp and control a solid
    state relay such as a crydon D1210 and just lock the trigger on the drill to
    the on position. This would switch the AC on and off as necessary.

    Thanks Jonathan!

    Just am not sure if I am going to need variable speed of the trigger
    built into the drill. The drill is being used for positioning. Am
    guessing the Stamp is amply fast to get small increments.

    Also, I need forward and reverse. Thought about using a servo and
    connecting just like in an RC plane.

    Take care,

    Jim,

    Could you, or anyone else out there, give a part number for the
    transistor. Am just a software guy. There is a really common NPN I
    believe, but can't think of the part #.

    Thanks,

    Arridh,

    Really like your idea. Yes, I did understand it.

    That is a very simple way to handle the coupling of the stepper motor
    and the bolt.

    My feedback loop is a digital measuring tape.

    Thanks so much,

    Thanks Alan,

    Everyone has been great! Think most of the bases are covered to get
    me started. I am sure to have more questions after I start
    building. Will be much more specific then.

    Jim,

    Could you, or anyone else out there, give a part number for the
    transistor. Am just a software guy. There is a really common NPN I
    believe, but can't think of the part #.

    Thanks,
    Frank

    Could you take the SSR idea a step further and do PWM on it? Make that boring
    drill variable speed?

    check out my web site for schematics that specify parts numbers and values.
