[0022] The present invention will be further described below with reference to the accompanying drawings and examples.

[0023] First embodiment: See also Figures 1 to 4 As shown, the CNC lathe with a cool air outlet function in the control area includes a casing 1 with a lathe body 4 inside, an operation port 101 and a control panel 2 are provided on the front end side of the casing 1, and the front of the casing 1 corresponds to the operation port 101 and the control panel 2 to form an operation area A and a control area B. A refrigeration system is provided on the casing 1, and the refrigeration system includes at least a first evaporator 32. The front end side of the casing 1 is equipped with a refrigeration fan 5 connected in series in the refrigeration system. The first evaporator 32 is arranged in the refrigeration fan 5, and a cool air outlet 501 is provided on the surface of the refrigeration fan 5 corresponding to the position of the first evaporator 32, and the cool air outlet 501 is directed toward the operation area A or / and the control area B.

[0024] This CNC lathe adds a cooling fan 5 on the casing, and connects the cooling fan 5 to the refrigeration system, so that the cooling fan 5 realizes the function of the air-conditioning indoor unit. The cooling fan 5 can blow cool air to the operator operating the lathe, lowering the operator's body temperature and the temperature of the surrounding working environment, making the operator's working environment more comfortable, reducing the operator's fatigue and sweating, and allowing the operator to stay at the post for a long time without having to move around frequently to cool off, thereby improving work efficiency.

[0025] The cooling fan 5 is a long strip structure and is vertically assembled and connected between the operation port 101 and the control panel 2. The cool air outlet 501 is opened on the surface of the cooling fan 5 along the height direction. Since each CNC lathe is usually equipped with one operator, the cooling fan 5 does not need to increase the blowing range. The cool air blown by the cooling fan 5 in this embodiment can at least cover the operator's head and body, and even the legs, so that the operator can enjoy the cooling fan 5 alone and stay comfortable at all times.

[0026] See also Figure 7 As shown, the refrigeration system also includes a cold liquid pipeline 31, a refrigerant pipeline 36, a condenser 37, a heat exchanger 34 and a compressor 35. The first evaporator 32 is connected in series with the first heat exchange tube 34a in the heat exchanger 34 through the cold liquid pipeline 31 to form a circulating water circuit. In addition, a circulating water pump 38 is also connected to the cold liquid pipeline 31 to promote the flow of cold liquid and improve the circulation efficiency. The condenser 37 and the compressor 35 are connected in series with the second heat exchange tube 34b in the heat exchanger 34 through the refrigerant pipeline 36 to form a circulating cold circuit.

[0027] During use, the CNC lathe exchanges heat with the first heat exchange tube 34a through the refrigerant cooling through the second heat exchange tube 34b, circulates the low-temperature water in the cold liquid pipeline 31, reduces the temperature of the first evaporator 32, absorbs the heat of the outside air, and finally blows out cool air.

[0028] The cold liquid pipeline 31, the refrigerant pipeline 36, the condenser 37, the heat exchanger 34 and the compressor 35 are all installed in a shell, thereby forming a hot and cold exchanger 33. The hot and cold exchanger 33 is installed on the top surface of the casing 1 so that the dissipated heat is directly discharged to the upper side of the CNC lathe without affecting the surrounding environment.

[0029] A temperature sensor 11 is provided inside the refrigeration fan 5 at the cool air outlet 501, and the temperature sensor 11 is electrically connected to the control panel 2; the temperature of the cool air can be detected by the temperature sensor 11, and the operating system of the refrigeration fan 5 can be integrated into the control panel 2, so that the operator can directly observe the set temperature through the control panel 2, and adjust the air volume or temperature according to the operator's own needs.

[0030] The cooling fan 5 includes a fan housing 51, in which a wind wheel 52 is rotatably disposed. The fan housing 51 is provided with a curved air outlet surface 502 facing directly in front of the operation port 101. The plurality of cool air outlets 501 are provided on the curved air outlet surface 502. This structure enables the cool air blown by the cooling fan 5 to cover the operator's position (operation area A or control area B), so that the cool air can be felt even when the operator is close to the operation port 101 or away from the operation port 101. A plurality of cool air outlets 501 are opened along the width direction of the arc-shaped air outlet surface 502, and an air supply angle θ is formed between each cool air outlet 501, and the air supply angle is at least 70° or above.

[0031] Second embodiment: In the second embodiment, see Figure 2 and Figure 5 As shown, it also includes a hydraulic station 6 for connecting to the hydraulic structure of the lathe body 4. The hydraulic station 6 is provided with an oil storage chamber 601 for storing hydraulic oil. The refrigeration system also includes a second evaporator connected in series to the cold liquid pipeline 31. The second evaporator is arranged in the oil storage chamber 601, and the hydraulic station 6 is connected in series or in parallel to the refrigeration system through the second evaporator; the temperature of the hydraulic oil in the hydraulic station 6 can be reduced through the cold liquid pipeline 31, thereby reducing the temperature of the structures near the oil circuits of the lathe body 4, reducing the thermal expansion of the mechanical structure, and improving the processing accuracy.

[0032] The hydraulic structure mainly includes one or more of a turret cutter disc locking structure, a spindle brake structure, a rotary oil cylinder, and a tail cone ejection structure.

[0033] In this embodiment, the hydraulic station 6 includes a hydraulic oil tank 61, and the interior of the hydraulic oil tank 61 defines an oil storage chamber 601. The second evaporator in the second embodiment is a first cold liquid coil 62. The cold liquid pipeline 31 is connected in series to the first cold liquid coil 62, and the first cold liquid coil 62 is arranged toward the bottom of the oil storage chamber 601; the first cold liquid coil 62 can increase the heat exchange time between the cold liquid and the hydraulic oil, thereby improving the efficiency of cooling the hydraulic oil.

[0034] In addition, the hydraulic station 6 also includes a hydraulic oil pump 63 and a hydraulic oil distributor 64 , which are installed on the top surface of the hydraulic oil tank 61 , and the hydraulic oil pump 63 is connected between the oil storage chamber 601 and the hydraulic oil distributor 64 .

[0035] Third embodiment: In the third embodiment: See Figure 2As shown, the lathe body 4 is provided with a liquid-cooled servo motor 7 for driving the spindle or the screw, and the refrigeration system further includes a second evaporator connected in series to the cold liquid pipeline. The second evaporator is provided on the liquid-cooled servo motor 7, and the liquid-cooled servo motor 7 is connected in series or in parallel to the refrigeration system through the second evaporator. The second evaporator in the third embodiment is a cooling liquid flow channel (not marked in the drawings) provided in the liquid-cooled servo motor 7 , and the cooling liquid pipeline 31 is connected in series in the cooling liquid flow channel.

[0036] Fourth embodiment: In the fourth embodiment: See Figure 2 and Figure 6 As shown, the lathe body 4 is provided with a screw rod 81 and a nut 82 connected to the screw rod 81. The refrigeration system also includes a second evaporator connected in series to the cold liquid pipeline. The second evaporator is provided on the nut 82, and the nut 82 is connected in series or in parallel to the refrigeration system through the second evaporator. When the nut 82 and the screw rod 81 are screwed together, friction will cause the temperature of the nut 82 and the screw rod 81 to rise, so the nut 82 needs to be cooled.

[0037] The second evaporator in the fourth embodiment is a cooling liquid channel 821 provided in the nut 82 . The cooling liquid channel 821 is provided around the outer circumference of the screw rod 81 , and the cooling liquid pipeline 31 is serially connected to the cooling liquid channel 821 .

[0038] Fifth embodiment: In the fifth embodiment: See Figure 2 As shown, it also includes a water tank 9 for storing coolant sprayed during cutting processing. A water storage chamber for storing cooling water is provided in the hydraulic station 6. The refrigeration system also includes a second evaporator connected in series to the coolant pipeline. The second evaporator is arranged in the water storage chamber 901, and the water tank 9 is connected in series or in parallel to the refrigeration system through the second evaporator. During the machining process of the CNC lathe, a cooling structure for spraying water on the tool is provided on the machining spindle. The cooling structure pumps water from the water tank 9 to reduce the temperature of the tool and the workpiece. Therefore, the water temperature in the water tank is lowered by the second evaporator, so that the sprayed water temperature is even lower, thereby improving the cooling effect of the tool and the workpiece. The second evaporator in the fifth embodiment is a second cooling liquid coil 91 , and the cooling liquid pipeline 31 is connected in series to the second cooling liquid coil 91 ; the second cooling liquid coil 91 can increase the heat exchange time between the cooling liquid and the cooling water, thereby improving the cooling efficiency of the cooling water.

[0039] Sixth embodiment: In the sixth embodiment: See Figure 2As shown, it also includes a control box 10 for installing the electronic control structure of the CNC lathe, and the refrigeration system also includes a second evaporator connected in series to the cold liquid pipeline. The second evaporator is arranged in the control box 10, and the control box 10 is connected in series or in parallel to the refrigeration system through the second evaporator; The control box 10 is mainly installed with an electric control structure for electrically connecting various components of the CNC lathe. The temperature of the electric control structure is reduced by the cooling liquid pipeline 31 to ensure the normal use of the electric control structure. The second evaporator in the sixth embodiment can also be a coil structure (not marked in the drawings).

[0040] In the second to sixth embodiments, when the hydraulic station 6, or the liquid-cooled servo motor 7, or the nut 82, or the water tank 9, or the control box 10 are connected in parallel to the refrigeration system, it is only necessary to add an additional cooling liquid pipeline 31 on the cold / hot exchanger 33, passing through the hydraulic station 6, or the liquid-cooled servo motor 7, or the nut 82, or the water tank 9, or the control box 10. When connected in series, the hydraulic station 6, or the liquid-cooled servo motor 7, or the nut 82, or the water tank 9, or the control box 10 are all connected in series behind the evaporator 32 along the conveying direction of the cold liquid pipeline 31; because the cooling requirement of the hydraulic station 6, or the liquid-cooled servo motor 7, or the nut 82, or the water tank 9, or the control box 10 is lower than that of the refrigeration fan 5, the lowest temperature cold liquid just coming out of the hot and cold exchanger 33 is preferentially passed through the refrigeration fan 5 to produce cool air.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
