How to hold the work piece with radius at the outer side while tightening a bolt (into the work piece) which requires 1300 N.m torque.

My questions is; is there any readily available fixture for this?

Thank you very much

 

How big is your OD? If you can't modify your geometry, 1300 Nm might be a large torque to hold with friction, especially if you don't want your surface damaged.

Are there other bolts, or other protrusions, you can use to hold it? Can you add a slot or spline or something somewhere to hold it?

 

Could you post a drawing?

 

You can use a vice to hold the workpiece. But jaws of the vice are hardened steel and can damage the material. So use a softer material (like copper or brass assuming your workpiece is made of steel) as a filler between the workpiece and the vice jaw.

 

Dear Mr.David,

Normally we can use V-Block arrangement for radius area ; so that you can firmly hold the work piece.
