Description

Technical Field

[0001] This utility model relates to the field of CNC lathes, specifically a CNC lathe with a cooling air function in the control area. Background Technology

[0002] Currently, when machining on a CNC lathe, the operator needs to stand or sit at a position in front of the operating port. Their work includes loading the workpiece before machining, unloading the finished product after machining, and handling unexpected situations that occur during CNC lathe machining. However, in the hot summer, the working environment temperature in the workshop rises, and combined with the heat generated by the CNC lathe during machining, the area around the CNC lathe becomes very stuffy, increasing the operator's fatigue and sweating. Therefore, the operator can only move back and forth between their work position and a position away from the CNC lathe or other places equipped with cooling equipment, which increases the operator's physical exertion. Moreover, the inability to constantly observe the machining situation of the CNC lathe and load / unload materials in a timely manner also leads to a decrease in work efficiency. Therefore, the applicant has improved and perfected the CNC lathe to solve the above problems for consumers to choose from. Utility Model Content

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

[0023] First embodiment: See Figures 1 to 4 As shown, the CNC lathe with cooling air function in the control area includes a housing 1 with a lathe body 4 inside. The front side of the housing 1 is provided with an operation port 101 and a control panel 2. The front of the housing 1 forms an operation area A and a control area B corresponding to the operation port 101 and the control panel 2. A cooling fan 5 is assembled and connected to the front side of the housing 1. The cooling fan 5 is provided with a cooling air outlet 501, which faces the operation area A and / or the control area B.

[0024] This CNC lathe has a cooling fan 5 added to the machine housing. The cooling fan 5 can blow cool air to the operator of the lathe, lowering the temperature of the operator's body and the surrounding working environment, making the working environment more comfortable, reducing operator fatigue and sweating, and allowing the operator to stay at the station for a long time without having to move around frequently to cool off, thereby improving work efficiency.

[0025] A refrigeration system is provided on the casing 1; the refrigeration system includes at least a heat exchanger 33, a cold liquid pipeline 31, and an evaporator 32. The heat exchanger 33 and the evaporator 32 are connected in series through the cold liquid pipeline 31. The evaporator 32 is installed inside the refrigeration fan 5. The refrigeration fan 5 is connected to the refrigeration system so that the refrigeration fan 5 can realize the function of an indoor air conditioning unit, which can blow out low-temperature cool air and further reduce the body temperature of the operator and the temperature of the surrounding working environment.

[0026] See Figure 7 As shown, the heat exchanger 33 includes a housing and a refrigerant pipeline 36, a condenser 37, a heat exchanger 34, and a compressor 35 disposed within the housing. The evaporator 32 is connected in series with the first heat exchange tube 34a in the heat exchanger 34 via a cold liquid pipeline 31 to form a circulating water circuit. 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 via the refrigerant pipeline 36 to form a circulating cold circuit.

[0027] During use, the CNC lathe exchanges heat through the second heat exchange tube 34b and the first heat exchange tube 34a through which water flows by refrigerant. The low-temperature water circulates in the cold liquid pipeline 31, which lowers the temperature of the first evaporator 32 and absorbs the heat from the outside air before finally blowing out cool air.

[0028] The heat exchanger 33 is installed on the top surface of the housing 1, so that the heat dissipated is directly discharged to the upper side of the CNC lathe and will not affect the surrounding environment.

[0029] 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 air blowing range. In this embodiment, the cool air blown by the cooling fan 5 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.

[0030] The cooling fan 5 includes a fan housing 51, a fan wheel 52 is rotatably disposed inside the fan housing 51, a cool air outlet 501 is opened on the fan housing 51, and an evaporator 32 is disposed between the fan wheel 52 and the cool air outlet 501. This structure allows the cool air blown by the cooling fan 5 to cover the operator's work area (operating area A or control area B), and the operator can feel the cool air even when near or away from the operating port 101.

[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. The hydraulic station 6 is connected in series or in parallel to the refrigeration system through a coolant pipeline 31. The coolant pipeline 31 can reduce the temperature of the hydraulic oil in the hydraulic station 6, 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 machining accuracy.

[0032] The hydraulic structure mainly includes one or more of the following: turret and cutterhead locking structure, spindle brake structure, rotary cylinder, and tail cone ejection structure.

[0033] In this embodiment, the hydraulic station 6 includes a hydraulic oil tank 61 for storing hydraulic oil. The hydraulic oil tank 61 is equipped with a first cooling coil 62, and the cooling pipeline 31 is connected in series with the first cooling coil 62. The first cooling coil 62 can increase the heat exchange time between the cooling fluid and the hydraulic oil, and improve the cooling efficiency of the hydraulic oil.

[0034] Third embodiment: In the third embodiment: see Figure 2 As shown, the lathe body 4 is equipped with a liquid-cooled servo motor 7 for driving the spindle or lead screw. The liquid-cooled servo motor 7 is connected in series or in parallel to the refrigeration system through the coolant pipe 31. The liquid-cooled servo motor 7 mainly includes the spindle and the spindle motor, and the spindle and the spindle motor can be connected in series on the coolant pipe 31 respectively.

[0035] Fourth embodiment: In the fourth embodiment: see Figure 2 and Figure 6 As shown, the lathe body 4 is provided with a lead screw 81 and a nut 82 connected to the lead screw 81. The nut 82 is connected in series or in parallel to the refrigeration system through the coolant pipe 31. When the nut 82 and the lead screw 81 are engaged, friction will cause the temperature of the nut 82 and the lead screw 81 to rise, so the nut 82 needs to be cooled down. The nut 82 has a cooling liquid flow channel 821 that surrounds the outer periphery of the lead screw 81, and the cooling liquid pipeline 31 is connected in series on the cooling liquid flow channel 821.

[0036] Fifth embodiment: In the fifth embodiment: see Figure 2 As shown, it also includes a water tank 9 for storing the coolant sprayed during cutting, the water tank 9 being connected in series or in parallel to the refrigeration system via a coolant pipeline 31; During the machining process of the CNC lathe, the machining spindle is equipped with a cooling structure for spraying water onto the tool. The cooling structure draws 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 reduced through the coolant pipe 31, making the sprayed water even cooler and improving the cooling effect on the tool and the workpiece.

[0037] A second cooling coil 91 is installed inside the water tank 9, and the cooling pipe 31 is connected in series with the second cooling coil 91; the second cooling coil 91 can increase the heat exchange time between the cooling liquid and the cooling water, and improve the cooling efficiency of the cooling water.

[0038] Sixth embodiment: In the sixth embodiment: see Figure 2 As shown, it also includes a control box 10 for installing the electrical control structure of the CNC lathe. The control box 10 is connected in series or in parallel to the refrigeration system through a coolant pipe 31. The control box 10 mainly installs the electrical control structure for electrically connecting various components of the CNC lathe. The temperature of the electrical control structure is reduced through the coolant pipe 31 to ensure the normal use of the electrical control structure.

[0039] In the second to sixth embodiments, when the hydraulic station 6, or liquid-cooled servo motor 7, or nut 82, or water tank 9, or control box 10 are connected in parallel to the refrigeration system, it is only necessary to add an additional cold liquid pipeline 31 through the hydraulic station 6, or liquid-cooled servo motor 7, or nut 82, or water tank 9, or control box 10 to the heat exchanger 33. When connected in series, the hydraulic station 6, or liquid-cooled servo motor 7, or nut 82, or water tank 9, or control box 10 are all connected in series behind the evaporator 32 along the conveying direction of the cold liquid pipeline 31. Since the cooling requirements of the hydraulic station 6, or liquid-cooled servo motor 7, or nut 82, or water tank 9, or control box 10 are lower than those of the refrigeration fan 5, the lowest temperature cold liquid that just came out of the heat exchanger 33 is preferentially passed through the refrigeration fan 5 to generate cool air.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
