Device for setting up work rollers

Abstract

This invention concerns a device used to set up work rollers in the work roller head of the deep rolling tool of a deep rolling unit designed to deep-roll grooves or radii that limit the journals of crankshafts in the axial direction. A guide roller for the work rollers is supported inside the work roller head and rotates freely about a rotation axis. Support and lateral guidance of the work rollers are provided by roller cages. The roller cages are attached to the housing of the work roller head by means of L-shaped brackets. The device is equipped with a receptacle for the work roller head corresponding to the receptacle in the deep rolling unit. A primary V-block contacting the circumference of the guide roller, as well as a secondary double-V-block contacting the free circumference of the work rollers from the outside, all cooperate with a measuring device with the help of which the position of the work rollers within the work roller head can be adjusted and checked.
