Description

Vertical machining center Technical Field The invention relates to the technical field of machining, in particular to a vertical machining center. Background In the field of modern machining, the vertical machining center is widely applied to machining and manufacturing of various parts by virtue of the characteristics of high efficiency, multiple functions and the like. Especially in the processing process of the sheet parts, the stability and the precision of the processing equipment are extremely high due to the characteristics of poor rigidity and thin thickness of the sheet parts. In structural design, the traditional vertical machining center generally adopts a rigid connection mode to assemble parts such as a machine tool base, an upright post, a workbench and the like, and in the machining process, the factors such as high-speed rotation of a machine tool main shaft, cutting force of a cutter and the like can generate larger vibration. These vibrations can be directly conducted to the worktable through the rigid structure of the machine tool, and when sheet parts are processed, vibrations and displacement are easily generated due to the influence of the vibrations because the vibration resistance of the parts is weak. Once the workpiece vibrates and displaces, the actual cutting position of the tool deviates from the preset programmed position, thereby greatly reducing the machining precision. At present, some damping measures are adopted in part of processing centers, such as mounting damping sizing blocks under a machine tool base or additionally arranging rubber damping layers between a workbench and an upright post, but the methods can only relieve vibration to a certain extent, and can not fundamentally solve the problem that the vibration is transmitted to a workpiece. Especially when carrying out the processing of high accuracy flake class part, current damping means is difficult to satisfy the processing requirement for the defective product rate is high in the course of working, has not only increased manufacturing cost, has still seriously influenced production efficiency and product quality. In view of this, a vertical machining center is proposed to solve the above-mentioned problems.
