Five-axis numerical control machine tool with novel cooling mechanism

Abstract

The invention discloses a five-axis numerical control machine tool with a novel cooling mechanism. The five-axis numerical control machine tool is novel in structural design, compact, high in precision and stable and comprises a knife handle fixed on a spindle and a workbench arranged below the knife handle, and the five-axis numerical control machine tool is characterized in that a linear motor is arranged on the workbench, a magnetic plate on the linear motor is fixed on the workbench, a rotor coil on the linear motor is located on the magnetic plate, the rotor coil is provided with a workpiece mounting plate, and the rotor coil moves in the Y-axis direction on the magnetic plate; and metal cooling tubes are arranged on the left side wall of the magnetic plate and the right side wall ofthe magnetic plate respectively, cooling liquid is circulated in the metal cooling tubes, and the metal cooling tubes are tightly attached to the side walls of the magnetic plate.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a five-axis numerical control machine tool equipped with a novel cooling mechanism. Background technique [0002] In the existing technology, in order to improve the precision of its CNC machine tools, the current CNC machine tools have gradually abandoned the traditional screw drive mode, and then use linear motors for transmission, and linear motors are composed of mover coils and are fixed on the machine tool frame. Composed of a magnetic plate on the upper body, the mover coil can reciprocate on the magnetic plate after being energized, and because the CNC machine tool needs to work for a long time in use, the coil in the linear motor body in this case will generate a lot of heat. If the heat is not eliminated in time, it will cause serious damage to the coil in the linear motor. In severe cases, it will cause the coil in the linear motor to burn out a...

[0002] In the existing technology, in order to improve the precision of its CNC machine tools, the current CNC machine tools have gradually abandoned the traditional screw drive mode, and then use linear motors for transmission, and linear motors are composed of mover coils and are fixed on the machine tool frame. Composed of a magnetic plate on the upper body, the mover coil can reciprocate on the magnetic plate after being energized, and because the CNC machine tool needs to work for a long time in use, the coil in the linear motor body in this case will generate a lot of heat. If the heat is not eliminated in time, it will cause serious damage to the coil in the linear motor. In severe cases, it will cause the coil in the linear motor to burn out and short circuit, which in turn will lead to a decrease in the accuracy of the CNC machine tool, an increase in the failure rate, and a production failure. Efficiency is reduced, therefore, it must be addressed for the above problems
