Low-vibration and low-noise fixed beam type gantry machining center

Abstract

The invention discloses a low-vibration and low-noise fixed beam type gantry machining center which comprises a cross beam and is characterized in that stand columns are fixed to the two sides of the cross beam, a tool rest is installed in the middle of the cross beam, a rotating shaft is connected to the lower portion of the tool rest through a bearing, a tool is rotationally connected to the lower portion of the rotating shaft, and an assembling groove is formed in the outer portion of the rotating shaft; a disc is fixed to the exterior of the assembling groove and is of a hollow structure, the center of the disc is detachably connected with the exterior of the assembling groove, a workbench is slidably connected to the lower portion of the cross beam, a plurality of extrusion blocks are installed in the disc, and pressure regulating valves are arranged in the extrusion blocks; and each pressure regulating valve comprises a valve block and a valve, one end of the pressure regulating valve is connected with an internal pipeline of the assembling groove, and the multiple extrusion blocks are all filled with methyl silicone oil. The low-vibration and low-noise fixed beam type gantry machining center has the characteristics that the cutting fluid can be adjusted in quantity and can be recycled.

Description

technical field [0001] The invention relates to the technical field of gantry machining centers, in particular to a low-vibration and low-noise fixed-beam gantry machining center. Background technique [0002] The gantry machining center refers to the machining center where the axis of the spindle is set perpendicular to the workbench. It is mainly suitable for machining large parts. During machining, the temperature of the machining center and the workpiece is very high. When the temperature is too high, its internal parts will be damaged. And processing tools, and when it is processed, it will also generate increased noise inside. In order to reduce its temperature, chip fluid cooling is usually used, but when using chip fluid, it often causes a lot of volume waste. Therefore, the design can be A low-vibration and low-noise fixed-beam type gantry machining center for saving and recycling the amount of cutting fluid is necessary.
