Description

Technical Field

[0001] The invention relates to an intelligent numerically controlled machine tool, in particular to an environmentally friendly intelligent numerically controlled machine tool applied in the field of machine tool components. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, input them into the CNC device through information carriers, and after calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing. It is the basic technology of modern processing and manufacturing industry.

[0003] The invention patent CN202210123601.6 specification discloses a water outlet system for an intelligent frequency conversion center of a machine tool. The invention arranges a primary filter plate and a secondary filter plate inside. When collecting water, the primary filter plate and the secondary filter plate can perform secondary filtering treatment on the collected water separately. During the water collection process, high-pressure water can be sent into the casing through the water inlet pipe. The water flow will continuously hit the driving blades of the primary cleaning component, and the surface pressure of the driving blades will change. The driving blades can drive the reciprocating screw to rotate, drive the cleaning scraper to move on the primary filter plate, and automatically clean the impurities on the primary filter plate to both sides, thereby effectively avoiding blockage in the primary filter plate. Moreover, the design can utilize the driving force generated during the transmission of the water body to make the primary cleaning component work, without the need for an additional driving source, and has good energy-saving performance.

[0004] In the above application, the driving force generated by the water transmission process is mainly used as the driving source, and no additional driving source is required. However, during the operation of the intelligent CNC machine tool, in addition to the energy consumption for preventing blockage, the energy consumed by cooling water transmission is also relatively large. If the cooling water is simply transmitted by frequency conversion from the perspective of impurity cleaning, it is difficult to achieve energy saving in the cooling water transmission process, which is not in line with the current environmental protection direction. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the energy consumed in cooling water transmission is relatively large. If the cooling water is transmitted by frequency conversion simply from the perspective of impurity cleaning, it is difficult to achieve energy saving in the cooling water transmission process.

[0006] In order to solve the above problems, the present invention provides an environmentally friendly intelligent CNC machine tool, including a machine tool base, the upper end of the machine tool base is fixedly connected with a longitudinal guide rail and a back platform, and the longitudinal guide rail and the back platform are perpendicular to each other, a processing platform matching itself is slidably connected to the longitudinal guide rail, a section of the back platform close to the processing platform is excavated with a height guide rail whose position matches the processing platform, an integrated machine platform matching itself is slidably connected in the height guide rail, a tool base and a pair of injection pipes whose positions match the lower end of the integrated machine platform are fixedly connected, the water outlets of the two injection pipes face the cutting tool, the lower end of the tool base is plugged with a cutting tool, the lower end of the integrated machine platform is fixedly connected with a detection plate, the detection plate is located on a side of the injection pipe away from the tool base, and the detection plate half covers the injection pipe, a control terminal is provided on a side of the back platform close to the processing platform, and a bracket is fixedly connected between the back platform and the control terminal; The detection plate includes a heat-conducting plate body, in which a plurality of integrated units are embedded, and a plurality of heat-conducting units are fixedly connected to one end of the plurality of integrated units close to the injection pipe, and a plurality of heat-conducting units are extended to the surface of the heat-conducting plate body close to the injection pipe at one end away from the integrated unit, and a temperature sensor is plugged into one end of the integrated unit away from the heat-conducting unit; A water storage unit is provided in the integrated machine, a power module is provided in the water storage unit, a frequency conversion module is provided in the power module, and the frequency conversion module is connected to the control terminal signal, the power module is connected to the water delivery module, and the water delivery module is connected to the injection pipe, a temperature sensor 2 is provided at the connection between the water delivery module and the injection pipe, and the temperature sensor 1 and the temperature sensor are connected to the control terminal signal.

[0007] In the above-mentioned environmentally friendly intelligent CNC machine tool, the cooling water utilization efficiency is judged according to the temperature change before and after the cooling water works, and then the cooling water demand is judged. Then, the power of the power module transmitted by the cooling water is effectively adjusted in combination with the frequency conversion technology, thereby reducing the cooling water consumption and reducing the energy loss of the cooling system, which is in line with the current environmental protection and energy-saving policies.

[0008] As a further improvement of the present application, multiple heat-conducting units connected to the same integrated unit are interlaced to form a mesh structure, and the multiple heat-conducting units are evenly distributed at one end of the surface of the heat-conducting plate body, thereby increasing the heat-conducting effect of the heat-conducting units and increasing the accuracy of detection by the temperature sensor.

[0009] As a further improvement of the present application, temperature sensor 1 includes a detection part connected to the integrated unit, and the detection part has an interference fit with the heat conduction plate body, and one end of the detection part away from the integrated unit is fixedly connected to an iron base plate, which makes it convenient for staff to use a magnet to take out the temperature sensor 1 as a whole, thereby facilitating installation and replacement work.

[0010] As a further improvement of the present application, one end of the heat conducting plate body close to the injection pipe is coated with a hydrophobic coating, and the hydrophobic coating has a smooth surface, which reduces the adhesion time of cooling water on the heat conducting plate body and reduces the real-time impact on the temperature detection of the temperature sensor.

[0011] As another improvement of the present application, when calculating the temperature average value, multiple temperature sensors remove the lowest temperature and the value with a temperature difference of 5% from the lowest temperature, thereby reducing the impact of temperature changes caused by heat transfer from the heat conducting plate on the final detection and removing temperature data that is not directly detected.

[0012] As another improved supplement to the present application, when multiple temperature sensors are calculating the temperature average value, the retained value is more than one-third of the total number of temperature sensors. When the data removed does not meet the requirements, the temporary average of the retained data is calculated, and the data closest to the temporary average is restored to meet the requirement of one-third of the total number. The final average is then calculated and sufficient data is retained to maintain the accuracy of the calculation.

[0013] As another improvement of the present application, a hole is bored at the lower end of the detection plate, and a feedback rod is inserted inside. The feedback rod includes a heating rod. The upper end of the heating rod is fixedly connected to a connection portion which is threadedly connected to the heat conducting plate body. A countersunk groove is bored at the end of the heating rod away from the connection portion. The feedback rod is connected to the control terminal signal, thereby realizing the detection of the working status of the temperature sensor 1, ensuring that the temperature sensor 1 is not defective when working normally, and increasing the accuracy of the detection data of the temperature sensor 1.

[0014] In summary, in this application, the temperature at the connection between the water delivery module and the injection pipe is recorded as T2, and the average temperature detected by multiple feedback rods on the surface of the detection plate is recorded as T1. The temperature difference ΔT between the two represents the cooling efficiency of the cooling water. When ΔT decreases per unit time, the cooling efficiency of the cooling water is low, and no excessive cooling water is required for water cooling. The frequency conversion module reduces the power of the power module under the control of the control terminal. On the contrary, when ΔT increases per unit time, the cooling efficiency of the cooling water is high, and more cooling water is required for water cooling. The frequency conversion module increases the power of the power module under the control of the control terminal. The cooling water utilization efficiency is judged according to the temperature change before and after the cooling water works, and then the cooling water demand is judged. In conjunction with the frequency conversion technology, the power of the power module transmitted by the cooling water is effectively adjusted, thereby reducing the cooling water consumption and reducing the energy loss of the cooling system, which is in line with the current environmental protection and energy-saving policies.

[0015] At the same time, a feedback rod for detecting temperature sensor 1 is added to the detection board, which realizes the detection of the working status of temperature sensor 1, ensures that temperature sensor 1 is not faulty when working normally, and increases the accuracy of temperature sensor 1 detection data.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-4An environmentally friendly intelligent CNC machine tool is shown, comprising a machine tool base 1, the upper end of the machine tool base 1 is fixedly connected with a longitudinal guide rail 2 and a back platform 4, and the longitudinal guide rail 2 and the back platform 4 are perpendicular to each other, a processing platform 3 matching itself is slidably connected to the longitudinal guide rail 2, a section of the back platform 4 close to the processing platform 3 is excavated with a height guide rail 5 matching the processing platform 3, an integrated machine platform 6 matching itself is slidably connected in the height guide rail 5, a tool base 8 and a pair of injection pipes 7 matching the positions are fixedly connected to the lower end of the integrated machine platform 6, the water outlets of the two injection pipes 7 face the cutting tool 9, the lower end of the tool base 8 is plugged with the cutting tool 9, a detection plate 10 is fixedly connected to the lower end of the integrated machine platform 6, the detection plate 10 is located on the side of the injection pipe 7 away from the tool base 8, and the detection plate 10 half covers the injection pipe 7, a control terminal 13 is provided on the side of the back platform 4 close to the processing platform 3, and a bracket is fixedly connected between the back platform 4 and the control terminal 13; The detection board 10 includes a heat-conducting plate body 1001, in which a plurality of integrated units 1002 are embedded, and a plurality of heat-conducting units 1003 are fixedly connected to one end of the plurality of integrated units 1002 close to the injection pipe 7, and one end of the plurality of heat-conducting units 1003 away from the integrated unit 1002 extends to the surface of the heat-conducting plate body 1001 close to the injection pipe 7, and a temperature sensor 11 is plugged into one end of the integrated unit 1002 away from the heat-conducting unit 1003; A water storage unit is provided in the integrated machine 6, a power module is provided in the water storage unit, a frequency conversion module is provided in the power module, and the frequency conversion module is connected to the control terminal 13 by signal, the power module is connected to the water delivery module, and the water delivery module is connected to the injection pipe 7, and a temperature sensor 2 is provided at the connection between the water delivery module and the injection pipe 7, and the temperature sensor 1 11 and the temperature sensor are connected to the control terminal 13 by signal.

[0020] See also Figure 5 and 7In the present application, the cooling water stored in the water storage unit enters the water delivery module and the injection pipe 7 in sequence under the action of the power module, and the cooling water flow injected from the injection pipe 7 impacts the cutting tool 9 to cool the cutting tool 9, and forms a water flow due to the impact, and is injected onto the surface of the detection plate 10. When the cooling water passes through the connection between the water delivery module and the injection pipe 7 and the surface of the detection plate 10, the temperature is detected, and the temperature passing through the connection between the water delivery module and the injection pipe 7 is recorded as T2, and the average temperature detected by multiple feedback rods 12 on the surface of the detection plate 10 is recorded as T1. The temperature difference ΔT between the two represents the cooling efficiency of the cooling water. When ΔT decreases within a unit time, the cooling efficiency of the cooling water is low, and no excessive cooling water is required for water cooling. The frequency conversion module reduces the power of the power module under the control of the control terminal 13. On the contrary, when ΔT increases within a unit time, the cooling efficiency of the cooling water is high, and more cooling water is required for water cooling. The frequency conversion module increases the power of the power module under the control of the control terminal 13. In this application, the cooling water utilization efficiency is judged according to the temperature change before and after the cooling water is working, and then the cooling water demand is judged. Then, the power module power transmitted by the cooling water is effectively adjusted in combination with the frequency conversion technology, thereby reducing the cooling water consumption and reducing the energy loss of the cooling system, which is in line with the current environmental protection and energy-saving policies.

[0021] See also Figure 6 , multiple heat-conducting units 1003 connected to the same integrated unit 1002 are staggered to form a mesh structure, and multiple heat-conducting units 1003 are evenly distributed at one end of the surface of the heat-conducting plate body 1001, thereby increasing the heat-conducting effect of the heat-conducting unit 1003 and increasing the accuracy of the detection of the temperature sensor 11. The temperature sensor 11 includes a detection part 1101 connected to the integrated unit 1002, and the detection part 1101 is interference fit with the heat-conducting plate body 1001. The end of the detection part 1101 away from the integrated unit 1002 is fixedly connected with an iron bottom plate 1102, so that the staff can use a magnet to take out the temperature sensor 11 as a whole, which is convenient for installation and replacement.

[0022] One end of the heat conducting plate body 1001 close to the injection pipe 7 is coated with a hydrophobic coating, and the hydrophobic coating has a smooth surface, which reduces the adhesion time of cooling water on the heat conducting plate body 1001 and reduces the real-time impact on the temperature detection of the temperature sensor 11.

[0023] When calculating the average temperature, the multiple temperature sensors 11 remove the lowest temperature and the value with a temperature difference of 5% from the lowest temperature, thereby reducing the impact of temperature changes caused by heat transfer from the heat conducting plate 1001 on the final detection and removing temperature data that is not directly detected.

[0024] When multiple temperature sensors 11 are calculating the temperature average value, the retained value is more than one-third of the total number of temperature sensors 11. When the data removed does not meet the requirements, the temporary average of the retained data is calculated, and the data closest to the temporary average is restored to meet the requirement of one-third of the total number, and then the final average is calculated, and enough data is retained to maintain the accuracy of the calculation.

[0025] The second implementation method: Figure 8-10 The detection board 10 shown has 1004 bored at the lower end thereof, a feedback rod 12 inserted into 1004, the feedback rod 12 comprising a heating rod 1201, the upper end of the heating rod 1201 is fixedly connected with a connecting portion 1202 threadedly connected to the heat conducting plate body 1001, a countersunk groove 1203 is bored at one end of the heating rod 1201 away from the connecting portion 1202, and the feedback rod 12 is signal-connected to the control terminal 13.

[0026] During the rest period of the intelligent CNC machine tool, the feedback rod 12 can be used to detect the temperature sensor 11 in the detection board 10. The temperature of the feedback rod 12 can be adjusted by the control terminal 13 to change the local temperature of the detection board 10. At the same time, the detection board 10 will also transmit heat. Therefore, in the process of detection by the feedback rod 12, the temperature detected by the temperature sensor 11 will change accordingly with the distance from the feedback rod 12. The temperature detected by the temperature sensor 11 at the corresponding position at different times can be used to determine whether the temperature sensor 11 is in a normal working state.

[0027] Compared with the first embodiment, in this embodiment, a feedback rod 12 for detecting the temperature sensor 11 is added to the detection board 10, thereby realizing the detection of the working status of the temperature sensor 11, ensuring that the temperature sensor 11 is not faulty when working normally, and increasing the accuracy of the detection data of the temperature sensor 11.

[0028] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
