I'm working on a disc brake balancing machine, as shown below this is a belt pulley drive and for alignment purposes I want motor to be able to move vertically as well as inwards outwards (to tighten the belt). Is there any clamp/adjuster design to achieve this? Disk brake balancing machine

Use a dovetail guide for the vertical movement and place the motor on it using elevating screws for the horizontal movement.

Dovetail guide

If you place the bottom plate of the contraption above (picture source) on the box and use the threaded holes on the top plate to mount the motor, you can move the motor up or down. Use screws in the holes at the side of the upper plate to adjust friction and lock both in one position.

enter image description here

Next, use something like the screws above (picture source) to fix the motor to the upper plate.

For vertical movement you could use a round guide and a tight fit rubber ring inside the holder to enable movement when you want to move it but for friction to keep it in place when you want to keep it still. For horozontal movement you could use scissor mechanism with screw which could control movement and act as a brake.
