  • 6" linear movement

    Hey guys and gals,
    need some help here. I need to automate a (light weight) panel to move about 6" back and forth. I'm guessing my best choice would be to get a linear actuator, but at $100 it's kind of a steep investment. What other options do i have for reliable repeatable automations?

    I was thinking lead screws but by the time i get everything i need it's going to be close to the linear actuator's cost but not be as sturdy.

    then i thought about getting smooth gliding track and a motor/wheel assembly with electronic switches at the beginning and end of travel.

    any ideas? thoughts? suggestions?

    thanks

    scott

            WIring is really easy.. I messed around with one, like a year ago. I bought it a discount auto for $19.99

              Hah, I saw them use a power antenna as an actuator on Pimp My Ride once. Another possible option would be to basically steal the design of a garage door opener, except scale it down.

                mbuchman, that's what he meant by lead screws

                Power antennas are easy. Power, Ground and switched power. Get some NICE roller-bearing drawer slides and mount the panel to that. Then have a power antenna or two push/pull it.

                  How fast do you need it to go? I have a friend that built a homemade CNC machine using plain old threaded rod for lead screws... as long as the panel is mounted on nice smooth rails/rods, even a crappy lead screw isn't that bad; mount it in a non-rigid manner so that the sloppier tolerances don't make it bind up (flexible coupling to the motor, etc). Just doesn't move very fast, because of the thread pitch.
                  But don't take it from me! here's a quote from a real, live newbie:

                      I've done a few motorization jobs with those aftermarket power window lift kits.... the kind that are cable operated & mount the motor remotely.... they can do some awsome things... may be a bit overkill for your app though...

                      I like to use either those, or salvaged sunroof motors that also work with cables.... even a smaller motor with cable operation could do... cables are nice because you can move the motor away to where you have space for it, & by being overkill insures a lifetime of trouble free usage...

                        I forgot to mention that you can use a windshield wiper motor with threaded rod from Home Depot.

                          these are great ideas guys. i'm looking into them all. if the price gets within $30 of the linear actuator though I'll probably just get one of them due to the ease of installation and reliability.

                            one car i did, I had a screen pop up out of the dash.... I used the motor from a me/be folding mirror assy... the motor is made by bosch....

                            I like to recycle car components because you know they are made for a very high cycle life....

                              i was over at www.motioncontrol.com and got the idea of using a flatbed scanner assembly. it has the rails and everything. just anohter idea
