Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machine tools, in particular to an anti-twisting structure of a working table of a machining center. Background Art
[0002] The machining center worktable is an accessory for computer numerical control machine tools. It usually has T-slots to facilitate the fixing of various workpieces. In order to compensate for the torque resistance and load, the existing machining center worktable adopts a thickened design. However, due to its bulky structure, the machine tool will move slowly during high-speed processing, increasing the load of the X-axis motor. When the X-axis moves to the edge of the stroke, due to the influence of the worktable's gravity, a lever effect will be generated, resulting in a loss of machine tool processing accuracy, affecting the machining work of the machining center worktable. In order to avoid the use of a torsion-resistant design with increased thickness on the machining center worktable, a new type of anti-twisting structure for the machining center worktable is needed.
