Inner-cooling component for machine tool accessory

Abstract

The invention provides an inner-cooling component for a machine tool accessory. The inner-cooling component for the machine tool accessory comprises the machine tool accessory, an inner-cooling connecting hose, a cylinder and an inner-cooling tool. The machine tool accessory comprises a rotation shaft. The rotation shaft is installed in the machine tool accessory along the horizontal direction, and the tail end of the rotation shaft is extended to the exterior of the machine tool accessory and is connected with the cylinder. The middle part of the rotation shaft is provided with a through hole along the axial direction. The tail end of the rotation shaft is radially provided with two water injection holes communicated with the through hole. One end of the inner-cooling connecting hose is connected with a water discharging hole of a machine tool spindle, and the other end is communicated with the cylinder, so cutting fluid discharged from the water discharging hole of the machine tool spindle is fed into the water injection holes. The inner-cooling component is capable of providing the inner-cooling function for the machine tool accessory, the accessory machining can be realized by many high-performance tools and high-rotation-speed cutting tools, and the machining efficiency and machining quality of the accessory are improved.

Description

technical field [0001] The invention belongs to the technical field of machine tool accessories, and in particular relates to an internal cooling assembly used for machine tool accessories, which improves the processing performance of the machine tool accessories. Background technique [0002] Domestic large-scale CNC machine tools all have their own matching right-angle, universal, and extension accessories. The accessories are assembled on the gantry machining center and boring machine to expand the processing range of the machine tool and realize polyhedron processing. The general accessories are considered for processing strength, and the rotating shafts are all designed with a solid body. The internal cooling function cannot be realized at all, and only the external coolant pouring method can be used. Internal cooling means that there is a cutting fluid inlet hole connected to the machine tool inside the tool, so that the tool When cutting, compared with ordinary tools,...

AI Technical Summary

Problems solved by technology

The general accessories are considered for processing strength, and the rotating shafts are all designed with a solid body. The internal cooling function cannot be realized at all, and only the external coolant pouring method can be used. Internal cooling means that there is a cutting fluid inlet hole connected to the machine tool inside the tool, so that the tool When cutting, compared with ordinary tools, it has the advantages of high cutting efficiency, small tool wear, light cutting and large cutting volume, which can greatly improve economic efficiency; the inability to use internal cooling directly leads to the failure of many high-speed and high-efficiency tools. use, the processing efficiency is low, and it cannot be compared with the direct processing efficiency of the spindle.
