Description

Reinforced stable structure of multi-head machine tool for die machining Technical Field The invention belongs to the technical field of machine tools, and particularly relates to a reinforced stable structure of a multi-head machine tool for die machining. Background Automobiles increasingly affect and even change our lives, and integral molds for automobiles are indispensable in automobile manufacturing, and the processing of the molds depends on machine tools. In the prior art, in order to increase flexibility, some machine tools adopt overhanging type cross beams, corresponding processing components are arranged at the front ends of the cross beams, and translational control of the processing components in the XYZ axis direction is realized through transverse movement and stretching of the cross beams on the underframe and lifting of the processing components. In addition, in order to improve efficiency, some machine tools also use two beams which move in a clutching way as a group, and the two outer sides of the beams are connected with the underframe through corresponding sliding tables. However, first, because of the front end processing assembly, the center of gravity is located outside the chassis most of the time, and as the extension distance increases, higher demands are also placed on the rigidity strength of the beam and the front end sagging resistance. Secondly, in order to better fold, a blocking and protecting device is not arranged on the inner side part of the cross beam generally, namely, the limiting effect on the cross beam in the transverse moving direction is weaker, and in the transverse moving process, the cross beam can generate larger deflection due to the action of inertia, so that the machining precision is affected.
