[0024] Please refer to Figs. 1-2In the embodiment, the power supply 103 is installed on one side of the frame 1, and a square mounting groove for installing the power supply 103 is formed on the one side of the frame 1. The power supply 103 is stably fixed on the frame 1 by being installed in the square mounting groove. Compared with placing the power supply 103 randomly, the embedded installation mode can avoid displacement of the power supply 103 due to vibration or collision during equipment operation, and ensure that the electrical connection between the power supply 103 and the numerical control machine tool always remains stable. The monitoring assembly includes a temperature sensor 301, a vibration sensor 302, a level 303, and a vertical level 304. The temperature sensor 301 is correspondingly arranged, and square mounting grooves for installing the temperature sensor 301 are formed on both sides of the frame 1. The temperature sensor 301 is correspondingly arranged and installed on both sides of the frame 1. The temperature sensor 301 adopts DS18B20, which can monitor the temperature of the numerical control machine tool from multiple positions. In this way, the temperature conditions of different parts of the equipment can be more comprehensively understood, and local overheating phenomena can be discovered in time, thereby improving the accuracy and reliability of temperature monitoring of the equipment.

[0025] Please refer to Figs. 2-3 In the embodiment, the vibration sensor 302 is installed at the corners around the top end of the frame 1. The vibration sensor 302 adopts LC0101. The level 303 is installed at the front end of the hydraulic distribution valve 205 at the bottom end of the frame 1. The vertical level 304 is installed on one side of the hydraulic rod 201. The vibration sensor 302 is installed at the corners around the top end of the frame 1. This multi-directional installation mode can comprehensively monitor the vibration conditions of the numerical control machine tool in all directions. By monitoring the vibration conditions at each corner, abnormal vibration during equipment operation can be discovered in time. The auxiliary assembly includes a cable slot 401, a drainage groove 402, a drainage port 403, and a wastewater tank 404. The cable slot 401 is formed in the frame 1. The drainage groove 402 is formed near the edge of the rear end of the frame 1. The drainage port 403 is formed in the center of the drainage groove 402. The wastewater tank 404 is threadedly connected to the bottom end of the drainage port 403. The cable slot 401 is formed in the frame 1, so that the cables related to the numerical control machine tool can be arranged in the cable slot. In this way, the cables can be prevented from being randomly scattered around the equipment, so that the working environment is more clean and orderly. The drainage groove 402 is formed near the edge of the rear end of the frame 1, and is connected to the wastewater tank 404 through the drainage port 403. The wastewater generated during the machining process of the numerical control machine tool can be discharged into the wastewater tank 404 through the drainage groove 402 and the drainage port 403 in time. This can prevent the wastewater from accumulating on the equipment and causing corrosion or other damage to the equipment, thereby prolonging the service life of the equipment.

[0026] In the process of work, when it is necessary to adjust the height of the machine tool according to the model of the numerical control machine tool or the requirement of special production environment, the lifting assembly is started, the hydraulic motor 206 is operated, the hydraulic distribution valve 205 is driven, the hydraulic oil flows between the hydraulic cylinder 204 and the four groups of hydraulic rods 201, the hydraulic rods 201 perform extension and retraction movement according to the pressure of the hydraulic oil, the height adjustment of the chassis is realized, and in the adjustment process, the shock absorbing pad 202 at the bottom end of the hydraulic rod 201 can effectively reduce the vibration caused by the change of height, so as to ensure the stable lifting of the numerical control machine tool, and the protective sleeve 203 at the top end of the hydraulic rod 201 protects the hydraulic rod 201 from external interference, so as to ensure the stability and reliability of the lifting process. When the numerical control machine tool starts to run, the temperature sensors 301 installed in the square mounting grooves on both sides of the frame 1 start to monitor the temperature of different parts of the numerical control machine tool in real time. These temperature sensors 301 will continuously collect temperature data. If the temperature of a part of the numerical control machine tool exceeds the preset safe temperature range during operation, the control console 102 will issue a warning. The vibration sensors 302 at the corners around the top end of the frame 1 synchronously monitor the vibration of the numerical control machine tool. If the parts of the equipment are loose, unbalanced or have other mechanical problems during the operation of the numerical control machine tool, the vibration frequency of the equipment will change. The vibration sensor 302 can sensitively capture the change of the vibration frequency and transmit the abnormal vibration signal to the monitoring system. The level meter 303 located in front of the hydraulic distribution valve 205 at the bottom end of the frame 1 monitors the level of the numerical control machine tool in real time. During the operation of the numerical control machine tool, various cables are placed in the cable trough 401 inside the frame 1. The cable trough 401 provides an orderly channel for the cables, so that the cables can be arranged neatly and avoid damage due to shaking, friction and other reasons during the operation of the equipment. When the numerical control machine tool uses cooling liquid or produces other waste water during the machining process, the waste water will flow along the drainage groove 402 at the top end of the frame 1 close to the rear end edge. Under the action of gravity, the waste water flows into the waste water tank 404 through the drainage port 403 at the center of the drainage groove 402. The waste water tank 404 will continuously collect waste water. When the waste water in the waste water tank 404 reaches a certain capacity, the operator can unscrew the waste water tank 404 from the drainage port 403, and perform waste water treatment or replace a new waste water tank 404 to ensure the normal operation of the drainage system.

[0027] Through the above steps, by setting the lifting assembly composed of hydraulic rod 201, hydraulic distribution valve 205 and hydraulic motor 206 at the corners around the bottom end of the frame 1, the height of the bottom frame can be conveniently adjusted. The fixed pad 207 is arranged at the bottom end of the hydraulic rod 201, and the shock pad 202 is installed at the center thereof. The fixed pad 207 can increase the contact area between the shock pad 202 and the hydraulic rod 201, so that the installation of the shock pad 202 is more stable. When the numerical control machine is running and vibration occurs, the shock pad 202 can more evenly bear the impact force from the equipment, avoiding the failure of the shock pad 202 due to excessive local pressure, thereby more effectively reducing the vibration transmission to the bottom frame and ensuring the stability and machining precision of the numerical control machine.
