Description

Technical Field

[0001] The utility model mainly relates to the technical field of machine tool components, in particular to a Zhangxuanqiao type integral π-shaped foot column type door beam. Background Art

[0002] The current gantry machine tools are mainly bar-type crossbeams and bridge-type bar-type crossbeams. The bottom of the beam and the top of the column are connected by screws. Since the cutting torque is mainly under the beam and the locking part of the column, this creates a torque amplification effect, which can easily cause the locking screws of the beam and the column to loosen. At the same time, the beam is fixed on the top of the column, and it is difficult to ensure the same height of the independent column. It is not easy to form a whole-surface locking, which can easily cause the beam to vibrate. On this basis, and in order to meet the diversified development of the market, a Zhang Xuan bridge-type integral π-shaped foot-column-type portal beam is proposed. Utility Model Content
