Description

Technical Field

[0001] The utility model belongs to the technical field of balancing devices, and in particular relates to a machine tool crossbeam balancing component. Background Art

[0002] At present, most machine tools usually adopt a cantilever beam body. The balanced suspension beam body includes a beam body, and both ends of the beam body have mounting screw holes, wherein the center line of the mounting screw holes is perpendicular to the center line of the beam body. Therefore, such a balanced suspension beam body has the disadvantage of poor torsional bearing and cannot meet the requirements of large torsional force. In addition, since the center of gravity of the cantilever beam body is far away from the support, it usually has a certain degree of downward inclination due to the effect of gravity after installation, thereby generating adverse radial forces on components such as rotating shafts and rotating bearings, and also affecting the balance between the beam body and the horizontal plane.

[0003] To this end, we propose a machine tool crossbeam balancing assembly. Utility Model Content
