Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a machine tool temperature control system. Background Technology

[0002] During the machining process, the moving parts such as motors, spindles, and belts inside the machine tool generate a lot of heat. This heat cannot be dissipated in time because it is blocked by the protective cover, causing the internal temperature of the machine tool to rise, which can damage the precision internal components such as motors, spindles, and belts at high temperatures.

[0003] Traditional solutions to this deformation typically involve oil cooling of the spindle or adding an electric fan to the motor for cooling. However, these methods only provide localized heat dissipation, and the heat dissipation speed is relatively slow, resulting in limited heat dissipation effects. Utility Model Content

[0004] This invention provides a machine tool temperature control system that can solve the problems mentioned in the background art.

[0005] A machine tool temperature control system includes: a machine tool, the machine tool being connected to an air supply pipeline, one end of the air supply pipeline being connected to the machine tool and the other end being connected to an air source, and a gas-liquid separator and a cooler being provided on the air supply pipeline along the airflow direction, the gas-liquid separator and the cooler cooperating to dry and cool the airflow entering the machine tool.

[0006] Preferably, the machine tool includes a sealing cover, a moving part is disposed inside the sealing cover, and the sealing cover is connected to the air supply pipeline.

[0007] Preferably, the sealing cover is equipped with a temperature sensor.

[0015] The beneficial effects of this utility model are:

[0016] The machine tool temperature control system has an external air supply pipeline connected to the machine tool. By setting up an air-liquid separator and the cooler, the cooling airflow can be continuously delivered to the inside of the machine tool, providing a cooling environment for the moving parts inside the machine tool. This allows all components to dissipate heat as a whole, and compared with the traditional local heat dissipation method, the heat dissipation speed is also faster, thus improving the heat dissipation effect.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1-2 As shown, the inventors discovered that during the machining process, the motor 4 and spindle 2 inside the machine tool generate a lot of heat when running at high speed. Since the machine tool needs to be covered by a protective cover 5, the inside of the machine tool is in a closed environment. The heat generated cannot be dissipated in time, which can easily lead to damage to the bearings inside the spindle 2 and motor 4, thereby reducing the accuracy of the machine tool.

[0026] Meanwhile, during the machining process, it is difficult for the machine tool's protective cover 5 to achieve a complete seal. During the machining process, the high-speed rotation of the spindle 2 atomizes the cutting fluid. The atomized cutting fluid will enter the machine tool through the gaps in the spindle 2, and eventually enter the motor 4, spindle 2, and belt 3, causing damage to the internal components of the motor 4 and spindle 2. The cutting fluid entering between the belt 3 and the pulley will also accelerate the wear of the gears between them, thereby increasing the maintenance cost of the machine tool.

[0027] like Figures 3-5 As shown in the figure, an embodiment of this utility model provides a machine tool temperature control system, including: a machine tool, a sealing cover 9, a moving part disposed inside the sealing cover 9, and a protective cover 5 disposed outside the sealing cover 9, which can prevent iron filings from entering the machine tool. The moving part includes a spindle 2, the spindle 2 is connected to a spindle housing 1, and the spindle housing 1 is connected to a motor 4. The sealing cover 9 encloses the moving part in the inner cavity of the cover. The cutting end of the spindle 2 is disposed outside the sealing cover 9, and other parts are disposed inside the sealing cover 9. When the cutting end of the spindle 2 rotates at high speed, the atomized cutting fluid is isolated outside the sealing cover 9, preventing it from acting on the moving part and avoiding wear of the moving part due to the cutting fluid. Moreover, the sealing cover 9 also has a heat preservation function.

[0028] The sealing cover 9 is also equipped with a temperature sensor 10 and an exhaust valve. The temperature sensor 10 can monitor the temperature inside the sealing cover 9 in real time. The exhaust valve is equipped with a silencer 8, which can reduce the noise of gas being discharged from the sealing cover 9.

[0029] like Figure 3 As shown, the machine tool is connected to the air supply line 6. One end of the air supply line 6 is connected to the machine tool, and the other end is connected to the air source 7. The air source 7 includes, but is not limited to, an air source or a nitrogen source. In this embodiment, an air source is used to reduce equipment costs. Before supplying gas to the air supply line 6, the air source 7 needs to filter the gas to prevent impurities in the gas from entering the machine tool.

[0030] The sealing cover 9 is connected to the gas supply line 6, which can supply cooling airflow to the cavity inside the sealing cover 9.

[0031] Specifically, a gas-liquid separator 12 and a cooler 11 are installed on the gas pipeline 6 along the gas flow direction. The gas-liquid separator 12 first filters the moisture in the gas flow to ensure that the gas flow is dry. The dried gas flow passes through the cooler 11, where it exchanges heat with the gas flow to cool it down and form a cooling gas flow. The cooler 11 includes, but is not limited to, finned tube coolers, water-cooled coolers, and evaporative coolers. Preferably, the cooler 11 is a water-cooled cooler.

[0032] In this embodiment, when the machine tool is started, the air source 7 delivers airflow to the air supply pipeline 6. During the flow, the airflow is first dried by the gas-liquid separator 12 and then cooled by the cooler 11 to form a cooling airflow. The cooling airflow enters the sealing cover 9 and carries away the heat generated by the high-speed rotating spindle 2, motor 4 and belt 3. After heat exchange, the cooling airflow is discharged from the exhaust valve. The silencer 8 reduces the noise of the discharged gas.

[0033] In this application, an external air supply line 6 is connected to the machine tool. By setting up an air-liquid separator 12 and the cooler 11, the cooling airflow can be continuously delivered to the inside of the machine tool, providing a cooling environment for the moving parts inside the machine tool. This allows all components to dissipate heat as a whole, resulting in faster heat dissipation compared to traditional localized heat dissipation methods, thus improving the heat dissipation effect and reducing the maintenance cost of the machine tool. All moving parts are installed inside a sealing cover 9, which reduces the noise generated during operation, improves the working environment for workers, and prevents cutting fluid from entering the components, reducing the failure rate of key machine tool components and enhancing the machine tool's market competitiveness.

[0034] In some embodiments, the temperature sensor 10 is electrically connected to a PLC controller 13, and the PLC controller 13 is electrically connected to the cooler 11. After receiving the temperature information fed back by the temperature sensor 10, the PLC controller 13 adjusts the cooling temperature of the cooler 11 according to the feedback information.

[0035] The operator can set the temperature feedback range of the temperature sensor 10 according to the actual needs of the machine tool processing. When the machine tool is started, the air source 7 delivers airflow to the air supply pipeline 6. During the flow, the airflow is first dried by the gas-liquid separator 12, and then cooled by the cooler 11 to form a cooling airflow. The cooling airflow enters the sealing cover 9 and carries away the heat generated by the high-speed spindle 2, motor 4, and belt 3. After heat exchange, the cooling airflow is discharged from the exhaust valve, and the silencer 8 reduces the noise of the discharged gas. When the temperature inside the sealing cover 9 exceeds the preset maximum temperature or falls below the preset minimum temperature, the temperature information data is fed back to the PLC controller 13. The PLC controller 13 adjusts the power of the water chiller 11 so that the temperature of the airflow cooled by the water chiller 11 matches the cooling temperature set by the operator for the machine tool, thereby realizing real-time adjustment of the internal temperature of the spindle box 1. Adding this temperature feedback mechanism can adjust the processing temperature of various precision components inside the machine tool, improving the processing accuracy of the machine tool's products.

[0036] Working principle: When the machine tool is started, the air source 7 delivers airflow to the air supply pipeline 6. During the flow, the airflow is first dried by the gas-liquid separator 12 and then cooled by the cooler 11 to form a cooling airflow. The cooling airflow enters the sealing cover 9 and carries away the heat generated by the high-speed spindle 2, motor 4 and belt 3. After heat exchange, the cooling airflow is discharged from the exhaust valve. The silencer 8 reduces the noise of the discharged gas.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
