Embodiment 1

[0036] like Figure 1 to Figure 3 , a spindle oil cooling system, comprising a spindle oil cooling device 3, an oil inlet pipeline 5, an oil outlet pipeline 6, an oil inlet sensing probe 10, and an oil outlet sensing probe 11; the spindle oil cooling device 3 includes an evaporator 31; The oil outlet end of the evaporator 31 communicates with the oil outlet pipeline 6; it also includes an economizer 4, an inlet pipeline 7, an outlet pipeline 8, a bypass regulating valve 9 and an inlet sensor probe 12. Wherein, the economizer 4 is in heat exchange communication with the evaporator 31 and its oil inlet end is in communication with the oil inlet pipeline 5; the liquid inlet pipeline 7 is in communication with the liquid inlet end of the economizer 4 and is used for communicating Cutting fluid; the liquid outlet pipeline 8 communicates with the liquid outlet end of the economizer 4 and is used for passing the cutting fluid; the bypass regulating valve 9 is arranged between the liq...

Embodiment 2

[0093] In this specific embodiment, the spindle oil cooling system of this example is basically the same as that of the embodiment, the difference is that the economizer 4 and the bypass regulating valve 9 of the spindle oil cooling system are changed to the cutting fluid cooling device 2, which can also achieve Energy saving purpose. However, because the cutting fluid cooling device 2 is inconvenient to obtain the set oil temperature of the spindle oil cooling system, it is impossible to precisely control the spindle oil temperature by controlling the heat exchange of the economizer 4 .

Abstract

The invention discloses a spindle oil cooling system. The system comprises a spindle oil cooling device, an oil inlet pipeline, an oil outlet pipeline, an oil inlet induction probe and an oil outlet induction probe. The spindle oil cooling device comprises an evaporator. The oil outlet end of the evaporator communicates with the oil outlet pipeline, and the spindle cooling device further comprisesan economizer, a liquid inlet pipeline, a liquid outlet pipeline, a bypass adjusting valve and a liquid inlet induction probe. The economizer is in heat exchange communication with the evaporator, the oil inlet end of the economizer communicates with the oil inlet pipeline, the liquid inlet pipeline communicates with the liquid inlet end of the economizer, the liquid outlet pipeline communicateswith the liquid outlet end of the economizer, the bypass adjusting valve is arranged between the liquid inlet pipeline and the liquid outlet pipeline, and the liquid inlet induction probe is arrangedon the liquid inlet pipeline. According to the spindle oil cooling system, waste heat of spindle oil can be recycled, and used for heating cutting liquid, electric heating of a cutting liquid coolingmachine is reduced, the aim of energy saving is achieved, meanwhile, temperature control precision of spindle oil can be ensured, the energy use rate is improved, and the invention further provides aspindle oil temperature control method and a machine tool cooling machine system with the spindle oil cooling system.

Description

technical field [0001] The present invention relates to the technical field of machine tool cooling, in particular to a spindle oil cooling system, a machine tool cooler system with the spindle oil cooling system, and a spindle oil temperature control method realized by the spindle oil cooling system . Background technique [0002] Existing CNC machining centers are generally equipped with spindle oil coolers and cutting fluid coolers. But these two cooling units work independently. When the machine tool is powered on, all supporting coolers are in running state. For example, when the oil temperature and cutting fluid temperature meet the set requirements, the oil pump and cutting fluid pump are also in working state. In most cases, the heat generated by the spindle is large, the spindle oil temperature is higher than the set temperature, and the spindle oil cooler is in a cooling state; the heat generated by the cutting side is small, and the cutting fluid is equipped wit...
