The utility model discloses a welded cross beam for a numerical control machine tool, which comprises a rectangular cross beam frame with hollow inner cavity. The inner cavity of the rectangular cross beam frame body is fixed with X-shaped reinforcing ribs through the whole rectangular cross beam frame body along the length direction, and the inner cavity of the rectangular cross beam frame body is fixed with a number of longitudinal reinforcing ribs in the direction perpendicular to the X-shaped reinforcing ribs plate, and the longitudinal reinforcing ribs plate is fixed equidistantly. Fixed with X-type stiffeners, the longitudinal stiffeners are connected with X-type stiffeners to form end-face stiffeners. The two corresponding sides of the rectangular cross-beam frame are evenly provided with a number of welding through-holes, which correspond to the longitudinal stiffeners respectively. The welded beams are welded through the combination of longitudinal stiffeners, X-type stiffeners and rectangular beams, forming an integral full-welded structure, which not only has good rigidity, stability and is not easy to deform, but also facilitates the processing of operators by reserving welding through holes and greatly improves the processing efficiency.

用于数控机床的焊接横梁
本技术涉及数控机床
,尤其涉及一种用于数控机床的焊接横梁。
技术介绍
现有的数控机床如铣床、镗床、车床等体积较为庞大,需要用到焊接横梁作为承重,安装其他较重的导轨、主轴等部件。现有的数控机床焊接横梁一般采用的是整体满焊式矩形横梁框体,内部具有与矩形横梁框体相垂直的加强筋。然而该类焊接横梁整体由于结构限制,内部加强筋焊接时非常不便,因此,其内部一般都是采用简单的平板类加强筋,从而导致焊接横梁整体刚性较差,受力后易发生变形。
技术实现思路
本技术的目的是针对现有技术的缺陷,提供一种结构简单、便于加工成型、整体刚性好、受力变形量小的用于数控机床的焊接横梁。本技术解决上述技术问题采取的技术方案是:一种用于数控机床的焊接横梁,包括内腔为中空的矩形横梁框体,所述矩形横梁框体的内腔沿长度方向固定有贯穿整个矩形横梁框体的X型加强筋板,且矩形横梁框体的内腔在垂直于X型加强筋板的方向上还等距固定有若干纵向加强筋板,所述纵向加强筋板与X型加强筋板固定连接,纵向加强筋板与X型加强筋板联接形成端面整面加强筋板,所述矩形横梁框体的两对应侧面分别均匀开设有若干焊接通孔,所 ...
