Problems solved by technology
If the heating of the motor spindle is not controlled, the resulting thermal deformation will seriously reduce the machining accuracy of the machine tool and the service life of the bearing. The typical cooling system uses circulating water cooling to take away the heat generated by the spindle, but because the spindle It is airtight. The conventional circulating cooling system can only take away the heat from the periphery of the spindle. The heat from the center of the spindle, that is, the shaft core, is difficult to take away. The shaft core usually has thermal deformation, which affects the machining accuracy of the machine tool.

The invention discloses a motor spindle with a cooled mandrel. The motor spindle comprises a rotating adapter assembly, a rotating connection shaft, a pull rod assembly, a mandrel, a sliding core and a knife handle; the mandrel and the pull rod assembly synchronously rotate; a cooling water inlet is formed in the rotating adapter assembly; a cooling water outlet is formed in the lower end of the knife handle, a water inlet and a water outlet are formed in the outer side wall of the pull rod assembly, and the motor spindle with the cooled mandrel comprises a water inlet channel and a water outlet channel; a water flowing channel is formed in the mandrel and comprises an upward flowing water channel and a downward flowing water channel which are arranged in pairs and a water turning area; one end of the water flowing channel is communicated with the water inlet, and the other end of the water flowing channel is communicated with the water outlet. According to the motor spindle with the cooled mandrel, by arranging the water flowing channel which vertically detours multiple times in the mandrel, cooling water flows back and forth multiple times in the mandrel, the mandrel heating problem is reduced, heat deformation of the mandrel is avoided, and the machining precision of a machine tool is improved.
Description
technical field [0001] The invention relates to the field of machine tool equipment, in particular to an electric spindle for cooling the shaft core. Background technique [0002] During the working process of the motor spindle, the main heat source comes from two aspects: one is the heating of the bearing, and the other is the heating of the built-in motor. If the heating of the motor spindle is not controlled, the resulting thermal deformation will seriously reduce the machining accuracy of the machine tool and the service life of the bearing. The typical cooling system uses circulating water cooling to take away the heat generated by the spindle, but because the spindle It is airtight, and the conventional circulating cooling system can only take away the heat from the periphery of the spindle. The heat from the center of the spindle, that is, the shaft core, is difficult to take away. The shaft core usually has thermal deformation, which affects the machining accuracy of...
