The invention relates to the technical field of electric spindles, in particular to a liquid metal temperature control system for an electric spindle. The liquid metal temperature control system for the electric spindle provided by the invention comprises a control system, an electric spindle housing and an electric spindle unit, wherein a closed coolant return pipe filled with liquid metal is arranged between the electric spindle housing and the electric spindle unit; the coolant return pipe is provided with an electromagnetic pump for pumping the liquid metal; and the electromagnetic pump isconnected with the control system. The liquid metal is adopted as a medium of a coolant, so that the thermal conductivity is good; the liquid metal which is not oxidized and of which the melting point temperature is close to the optimal working temperature of the electric spindle unit can be selected, the flow of the electromagnetic pump can be adjusted through the control system and the temperature of the coolant return pipe is effectively adjusted through changing the flow, so that the heat dissipation effect is further improved. In addition, the liquid metal temperature control system is compact in structure and reasonable in design; and a cooling and temperature control device does not need to be additionally arranged outside the electric spindle housing, so that the production cost is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of electric spindles, in particular to a liquid metal temperature control system for electric spindles. Background technique [0002] High-speed machining machine tool motorized spindle unit (HVCT), referred to as "electrical spindle", is a new technology that integrates machine tool spindles and spindle motors in the field of CNC machine tools in recent years. The electric spindle is a set of components, including the electric spindle body, high-frequency frequency conversion device, oil mist lubricator, cooling device, built-in encoder, tool change device, etc. This transmission method of combining the spindle motor and the machine tool spindle separates the spindle components from the machine tool transmission system, so the electric spindle is also called the electric spindle unit. It uses a high-frequency AC motor, so it is also called a high-frequency spindle. The electric spindle has no intermediate...
