Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1: referring to fig. 1-4, a novel roller structure of a laser cutting machine workbench comprises a workbench side rectangular tube 1, a deep groove ball bearing 2 is arranged inside the workbench side rectangular tube 1, an eccentric sleeve 3 is fixed at the bottom end of the deep groove ball bearing 2, a roller shaft 4 is arranged at the bottom end of the eccentric sleeve 3, a roller 5 is arranged outside the deep groove ball bearing 2, and a hexagon nut 6 is arranged outside one side of the roller shaft 4;

the deep groove ball bearing 2 is arranged on the eccentric sleeve 3, and the axial positioning is positioned by a shaft shoulder on the eccentric sleeve 3 and an elastic retainer ring for a shaft;

the eccentric sleeve 3 and the roller shaft 4 are in threaded connection, and the relative positions of the eccentric sleeve and the roller shaft are fixed through fixing bolts;
