Table-top tensile tester
Table-top tensile tester
(OP)
Hello,
I'm trying to find or build a small table-top tensile tester. Neither of the grips can be stationary-- both must move outward from a center point, i.e. driven by the same screw. It must also have load measurement. The specifications beyond this are not important, as it will serve as a demo device for our product and the specimen will be designed to match. Any ideas as to where I should start? Thanks!

What kind of ideas do you have?

You could also do the above with ball screws and measure the force with the drive motor torque if using a servo.
You could also use a high reduction gear motor and a chain or polychain with one gripper attached to either side on the belt, top and return.
You could use a double rack and pinion.
You could use a double crank.
How much force, stroke, accuracy and money?

Budget is $3,000. Accuracy is not important. Force is probably no more than 5 lbs.
Are there any turnbuckles designed to be motor-driven, i.e. outside of the Home Depot variety? This sounds like the simplest solution, but after searching I'm not coming up with any good options.
The double rack might also be promising. I'll start looking into that. I'm not sure we'll have money left over for ballscrews after the motor and controller-- if we can even afford those. Any speficic brand name or product recommendations? Thanks again.
