Machine tool sliding plate structure

Abstract

The invention discloses a machine tool sliding plate structure. Mounting platforms of a guide track sliding block are arranged on both the upper surface and the lower surface of the machine tool sliding plate structure, oil holes are formed in side surfaces of the mounting platforms, and the oil holes are beneficial for flowing of oil, so that a gap caused by surface roughness between a sliding block and a sliding plate can be filled, heat transfer can be enhanced, part of heat in the heat conduction process can be carried away, then thermal deformation of the sliding plates can be reduced, and meanwhile a lubricating function can be achieved for guide track pairs; the lower surface is saddle-shaped and is internally provided with a cross-shaped rib plate; an X-direction ball screw pair screw nut base is integrally connected with the sliding plate and is arranged at a central part of the lower surface; honeycomb rib plates are arranged on the upper surface and the lower surface; a Y-direction ball screw pair screw nut base is arranged at one end of the upper surface; under the condition that the Y-direction stroke is ensured, the length of a ram can be reduced. Compared with a conventional sliding plate, the volume and the mass of the improved sliding plate can be both reduced, a weight system can be conveniently arranged on the ram on the sliding plate, the strength and the rigidity of the structure can be improved, thermal deformation can be reduced, and the machining precision of a machine tool can be improved.

[0003] Geometric error and thermal deformation are the main error sources that affect the machining accuracy of machine tools. The former can be reduced by advanced manufacturing technology. However, when the machine tool is working, due to the long extension of the ram, the vibration is more obvious. Therefore, it is necessary to set a counterweight system to reduce its bending deformation, and the traditional skateboard is generally made very long, which is not conducive to the installation of the counterweight system; when the machine tool is running, the heat generated by the motor, the friction heat of the transmission system and the change of the external environment temperature will cause the temperature distribution of the skateboard Unevenness, which in turn produces thermal deformation, which affects the processing accuracy. The traditional skateboard is equipped with a servo motor, and its thermal deformation is serious.
