brake-holding-clamping methods for linear motion
brake-holding-clamping methods for linear motion
(OP)
I'm designing a positioning device using
=> end-supported linear rails like Thomson products
=> integrated rail/supports with a hand-cranked ballscrew
I want to move it a location, then clamp it in place.
Can anyone suggest methods to do this or products available so that I don't have to re-invent the wheel?
Thx

Essentially there are very few options for ballscrew/linear motion braking/holding. The most popular system appears to be a bulky hydraulic clamp arrangement. I must admit I have never seen one and only been told about them.
One option is to use a brake or clutch on the ball screw. If you use a spring applied brake then simply energise to release and allow movement. Warner, KEB, Lenze, Mayr etc all offer this sort of kit.
Manual systems like the one suggested by Barry1961 work well if you can get access to the machine to fix them and you don't want to move them often. If more flexibility is required you will almost certainly have to sort it out yourself.
Good luck

When I built ballscrew actuators for Warner Electric we used a wrap spring brake to prevent backdriving but our acme screw actuators had no brake.

They look as if they might even do something for Thomson linear shafting as well - check with them.
