Description

TECHNICAL FIELD

[0001] The application relates to the technical field of numerical control machining, and particularly relates to a cooling liquid circulating device of a numerical control machining center. BACKGROUND

[0002] The numerical control machining center plays a vital role in modern manufacturing industry, and a large amount of heat is generated in the machining process. If the heat is not cooled in time, the machining precision will be affected, and problems such as accelerated tool wear and workpiece deformation can be caused. Therefore, the cooling liquid circulating device is an indispensable matching device of the numerical control machining center. The cooling liquid circulating device is responsible for delivering the cooling liquid to the machining area for cooling, and then recycling, filtering and cooling for recycling, so as to ensure the stability and efficiency of the machining process.

[0003] The traditional cooling liquid circulating device of the numerical control machining center has many defects. In terms of filtering of the cooling liquid, the traditional device usually adopts a simple filter screen structure, and the filtering effect is limited. The micro impurities and metal scraps in the cooling liquid cannot be effectively removed. With the passage of time, the impurities will continuously accumulate in the cooling liquid, affecting the flowability and heat dissipation performance of the cooling liquid, and then reducing the cooling effect. In terms of the cooling mode, the traditional device mostly adopts a single air cooling or water cooling mode. The air cooling mode has low cooling efficiency in a high-temperature environment. The water cooling mode can cause pipeline corrosion and scaling due to water quality problems, affecting the service life and cooling effect of the device. In addition, the traditional device is not reasonably designed in terms of storage and buffering of the cooling liquid. The problems of unstable supply of the cooling liquid and large pressure fluctuation are prone to occur, affecting the machining quality. Moreover, the traditional device lacks effective means for removing the magnetic impurities such as iron scraps in the cooling liquid, so that the iron scraps are circulated in the system, accelerating the wear of the device and reducing the reliability and stability of the device. In view of the above problems, the application provides a cooling liquid circulating device of a numerical control machining center for solving the above problems. SUMMARY

[0004] In order to solve the problems of incomplete filtering of the cooling liquid of the traditional numerical control machining center, single cooling mode and difficult removal of iron scraps, the application aims to provide a cooling liquid circulating device of a numerical control machining center.

[0005] To solve the above technical problems, the application adopts the following technical scheme: a cooling liquid circulating device of a numerical control machining center, comprising a storage device, a cooling device and a machining center. The storage device is a hollow cuboid structure, and the inside thereof is divided into three layers according to the height. The upper part is a main storage bin. A plurality of filter screens are fixedly installed on the lower surface of the main storage bin. A first temperature sensor is fixedly installed on the center of the upper surface in the main storage bin. The middle part is a buffer bin. A plurality of elastic buffer devices corresponding to the number of filter screens are fixedly installed in the buffer bin along the vertical direction. The lower part is a sediment bin. A hopper is fixedly installed in the middle part of the inside of the sediment bin.

[0006] Preferably, the elastic buffering device comprises an elastic bag made of rubber, and an adsorption core is arranged coaxially inside the elastic bag, the adsorption core comprises an insulating layer made of polyvinyl chloride, and an iron core is fixedly installed inside the insulating layer, and an electromagnetic coil is arranged around the gap between the outer cylindrical surface of the iron core and the insulating layer.

[0007] Preferably, the right side of the main storage bin is provided with a cooling device, a first water pump is fixedly installed on the upper surface of the cooling device, a cooling liquid outlet is formed in the right side wall of the main storage bin, the cooling liquid outlet extends outward and is fixedly connected with the first water pump, and the outlet of the first water pump extends through the cooling device and into the heat exchange bin inside the cooling device.

[0008] Preferably, a heat exchange water pipe is arranged in the heat exchange bin, the heat exchange water pipe is arranged in a serpentine shape, a second temperature sensor is fixedly installed on one side of the heat exchange bin, and a water cooling liquid outlet and a water cooling liquid inlet are formed in the side wall of the heat exchange bin, both of which extend through the side wall of the cooling device and to the outside.

[0009] Compared with the prior art, the present application has the following advantages:

[0010] 1. The present application is provided with a multi-layer filtering structure, the filter screen on the lower surface of the main storage bin can preliminarily intercept larger particulate impurities in the cooling liquid, the funnel in the sedimentation bin can promote the impurities to be deposited and concentrated at the bottom under the action of gravity by virtue of the conical structure and the bottom leak hole, and the adsorption core in the elastic buffering device can adsorb tiny metal debris by means of electromagnetic principle. In this way, various impurities in the cooling liquid can be removed in all directions, the cooling liquid can be effectively ensured to maintain good fluidity and heat dissipation performance at all times, the possibility of equipment failure due to impurity accumulation is greatly reduced, the production efficiency is significantly improved, and the processing process can be ensured to continuously and stably proceed.

[0011] 2. The present application adopts a cooling mode in which the heat exchange water pipe is arranged in a serpentine shape in the heat exchange bin and cooperates with the external water cooling liquid circulation system. The serpentine arrangement greatly increases the contact area and time of the cooling liquid with the heat exchange water pipe, and the heat exchange efficiency is significantly improved. At the same time, this mode avoids direct contact of the cooling liquid with the external water source, reduces the risk of pipe corrosion and fouling caused by water quality problems. In addition, the first water pump and the second water pump in the equipment can ensure that the cooling liquid flows stably and quickly in the circulation system, further enhancing the cooling effect, so that the equipment can adapt to different processing environments and processing intensities, and ensure the stable operation of the processing center.

[0012] 3、The elastic buffering device of the present application, the adsorption core utilizes electromagnetic principle to adsorb iron filings.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] As Figures 1-8 shown, the present application provides a numerical control machining center cooling liquid circulating equipment, which comprises a storage device 1, a cooling device 2 and a machining center 3. The storage device 1 is a hollow cuboid structure, which is divided into three layers according to height. The upper part is a main storage bin 11. A plurality of filter screens 112 are fixedly installed on the lower surface of the main storage bin 11. A first temperature sensor 111 is fixedly installed on the upper surface center of the main storage bin 11. The middle part is a buffer bin 12. A plurality of elastic buffer devices 121 corresponding to the number of filter screens 112 are fixedly installed in the buffer bin 12 along the vertical direction. The lower part is a sedimentation bin 13. A funnel 131 is fixedly installed in the middle part of the sedimentation bin 13.

[0025] By adopting the above technical scheme, the main storage bin 11 is mainly used for storing the cooling liquid, the filter screen 112 on the lower surface of the main storage bin 11 can preliminarily filter the cooling liquid, intercept the larger impurities in the cooling liquid, and prevent the impurities from entering the subsequent circulating system, thereby avoiding the adverse effects of the impurities on the equipment, such as abrasion and blockage. The first temperature sensor 111 on the upper surface of the inside of the main storage bin 11 can monitor the temperature of the cooling liquid in real time, and when the temperature exceeds the set range, a signal can be sent in time so that the operator can take corresponding measures to ensure that the temperature of the cooling liquid is in the appropriate working range and to ensure the normal operation of the machining center. The elastic buffering device 121 in the buffer bin 12 can play a buffering role in the cooling liquid circulation process, stabilize the pressure of the cooling liquid, and reduce the impact of pressure fluctuations on the equipment. On the other hand, the elastic buffering device 121 can adsorb the small metal debris and other impurities in the cooling liquid, further purify the cooling liquid, and improve the quality of the cooling liquid. The hopper 131 in the middle of the inside of the sedimentation bin 13 can make the impurities in the cooling liquid gradually sediment to the bottom of the hopper under the action of gravity. By regularly cleaning the hopper, the sedimentary impurities in the cooling liquid can be effectively removed, the service life of the cooling liquid can be prolonged, and the stable operation of the entire cooling liquid circulating system can be ensured.

[0026] The elastic buffering device 121 includes an elastic capsule 1211, the material of the elastic capsule 1211 is rubber, and a adsorption core 1212 is arranged at a coaxial position in the inside of the elastic capsule 1211. The adsorption core 1212 includes an insulation layer 12121, the material of the insulation layer 12121 is polyvinyl chloride, and an iron core 12123 is fixedly installed in the inside of the insulation layer 12121. An electromagnetic coil 12122 is arranged around the gap between the outer cylindrical surface of the iron core 12123 and the insulation layer 12121.

[0027] By adopting the above technical scheme, the elastic bag 1211 is made of rubber, and its good flexibility and elasticity play a key role in the cooling liquid circulation. When the cooling liquid pressure fluctuates, the elastic bag 1211 can effectively buffer the pressure change by virtue of its own elastic deformation, prevent excessive pressure impact on the equipment, ensure stable flow of the cooling liquid, and the adsorption core 1212 is located coaxially inside the elastic bag 1211. The insulating layer 12121 is made of polyvinyl chloride material, which has excellent insulation performance. When the electromagnetic coil 12122 is energized, it can reliably prevent current leakage and eliminate electrical problems such as short circuit, ensuring the safe operation of the equipment. The iron core 12123 is fixedly installed in the insulating layer 12121. When the electromagnetic coil 12122 is energized, the iron core 12123 can significantly enhance the magnetic field strength, providing strong magnetic force for adsorbing small metal debris and other impurities in the cooling liquid, effectively improving the purity of the cooling liquid, reducing the wear and corrosion of impurities on the equipment, prolonging the service life of the equipment, and ensuring the machining precision and stability of the machining center. The electromagnetic coil 12122 is wrapped around the gap between the outer cylindrical surface of the iron core 12123 and the insulating layer 12121. By precisely controlling the current on and off, the presence or absence of the magnetic property of the adsorption core 1212 can be conveniently controlled. When adsorbing impurities, the electromagnetic coil 12122 is energized to generate a magnetic field, and when cleaning impurities, the electromagnetic coil 12122 is de-energized to eliminate the magnetic field. The operation is simple, energy-efficient, and greatly improves the practicality and reliability of the equipment.

[0028] The right side of the main storage bin 11 is provided with a cooling device 2, and the upper surface of the cooling device 2 is fixedly installed with a first water pump 23. The right side wall of the main storage bin 11 is provided with a cooling liquid outlet 113, which extends outward and is fixedly connected with the first water pump 23. The outlet of the first water pump 23 extends through the cooling device 2 to the heat exchange bin 21 inside the cooling device 2.

[0029] By adopting the above technical scheme, the cooling device 2 arranged on the right side of the main storage bin 11 is used to cool the circulating cooling liquid, ensuring that the cooling liquid can effectively take away the heat generated by the machining center. The first water pump 23 on the upper surface of the cooling device 2 is one of the power sources for the cooling liquid circulation. It is fixedly connected with the cooling liquid outlet 113 arranged on the right side wall of the main storage bin 11, so that the cooling liquid in the main storage bin 11 can be pumped out. The position and connection mode of the cooling liquid outlet 113 ensure that the cooling liquid can flow smoothly from the main storage bin 11 to the first water pump 23. The outlet of the first water pump 23 extends through the cooling device 2 and extends to the heat exchange bin 21 inside the cooling device 2, so that the pumped-out cooling liquid can accurately enter the heat exchange bin 21 for heat exchange cooling. This layout and connection mode realizes the orderly flow of the cooling liquid from storage to cooling, ensures the normal operation of the entire cooling liquid circulation system, helps to maintain the machining center working at an appropriate temperature, improves the machining precision and service life of the equipment.

[0030] The heat exchange warehouse 21 is provided with a heat exchange water pipe 211 arranged in a serpentine shape. The heat exchange warehouse 21 is fixedly provided with a second temperature sensor 212 on one side. The sidewall of the heat exchange warehouse 21 is provided with a water cooling liquid outlet 213 and a water cooling liquid inlet 214, which penetrate the sidewall of the cooling device 2 and extend to the outside.

[0031] By adopting the above technical scheme, the heat exchange water pipe 211 is arranged in a serpentine shape in the heat exchange warehouse 21. This ingenious design increases the flow and residence time of the cooling liquid in the heat exchange warehouse 21, thereby greatly improving the heat exchange efficiency between the cooling liquid and the heat exchange water pipe 211. The cooling liquid is transported from the storage device to the heat exchange water pipe 211 through the pipeline. During the flow in the heat exchange water pipe 211, heat is effectively dissipated. The water cooling liquid inlet 214 and the water cooling liquid outlet 213 on the sidewall of the heat exchange warehouse 21 are respectively connected to the external water cooling liquid circulation system. The external water cooling liquid flows into the water cooling liquid inlet 214, surrounds the outside of the heat exchange water pipe 211. Since the cooling liquid in the heat exchange water pipe 211 has a high temperature, heat is transferred to the external water cooling liquid. After absorbing heat, the temperature of the water cooling liquid rises, and then flows out from the water cooling liquid outlet 213. Thus, the function of cooling the cooling liquid in the heat exchange water pipe 211 by the external water cooling liquid circulation is realized. The second temperature sensor 212 installed on one side of the heat exchange warehouse 21 monitors the temperature of the cooling liquid in real time. The operator can determine whether the temperature of the cooling liquid is appropriate according to the temperature data, so as to timely adjust the operation state of the equipment, ensure that the temperature of the cooling liquid always meets the heat dissipation requirements of the machining center, and ensure that the machining process is stable and efficient. At the same time, the cooling liquid may be added with components for flushing the machine tool to clean the surface of the machine tool. However, these components will not mix with the external water cooling liquid. The two are completely separated by the wall of the heat exchange water pipe 211 and independently circulate without interfering with each other. In this way, the cleaning and heat dissipation functions of the cooling liquid to the machine tool are ensured, and the pure cooling effect of the water cooling liquid is effectively played, maintaining the normal operation of the entire cooling liquid circulation system and the machining center.

[0032] The left sidewall of the sedimentation warehouse 13 is provided with a cooling liquid inlet 132. The cooling liquid inlet 132 is connected to the cooling liquid pool 31 of the machining center 3 through a cooling liquid conveying pipe 311. The cooling liquid conveying pipe 311 is fixedly provided with a spherical check valve 3111.

[0033] By adopting the above technical scheme, the cooling liquid inlet 132 formed in the bottom of the left side wall of the sedimentation bin 13 provides an entrance for the cooling liquid in the cooling liquid pool 31 of the machining center 3 to flow back to the sedimentation bin 13. When the used cooling liquid in the machining process of the machining center 3 needs to be recycled back to the equipment for treatment, the cooling liquid conveying pipe 311 is connected with the sedimentation bin 13. The spherical check valve 3111 fixedly installed on the cooling liquid conveying pipe 311 plays a key one-way conduction role, ensuring that the cooling liquid can only flow from the cooling liquid pool 31 of the machining center 3 to the sedimentation bin 13, and cannot flow back. This feature effectively prevents the cooling liquid that has been preliminarily filtered or treated in the sedimentation bin 13 from flowing back to the machining center 3 during the operation of the equipment, avoiding pollution to the machining center 3 or affecting the normal work of the machining center 3. At the same time, the flow direction of the entire cooling liquid circulation system is stable, so that the cooling liquid can be treated in sequence according to the predetermined path, such as sedimentation, filtration, cooling, etc., improving the efficiency of the recycling of the cooling liquid, and helping to maintain the stable operation of the entire cooling liquid circulation system of the numerical control machining center, ensuring the machining quality and the normal service life of the equipment.

[0034] The bottom of the rear side wall of the sedimentation bin 13 is provided with a closing door 133. The closing door 133 is connected with the side wall of the sedimentation bin 13 through a hinge, and a sealing gasket is arranged at the edge of the closing door 133.

[0035] By adopting the above technical scheme, the closing door 133 at the bottom of the rear side wall of the sedimentation bin 13 provides a convenient channel for cleaning the impurities accumulated in the sedimentation bin 13. The closing door 133 is connected with the side wall of the sedimentation bin 13 through a hinge, which makes the closing door 133 open and close flexibly. When the sedimentation bin 13 needs to be cleaned, the operator can easily open the closing door 133 to conveniently remove the impurities deposited at the bottom of the sedimentation bin 13. When the equipment is normally operated, the closing door 133 is closed, and the sealing gasket arranged at the edge of the closing door 133 plays an important role. The sealing gasket can effectively fill the gap between the closing door 133 and the side wall of the sedimentation bin 13, preventing the cooling liquid from leaking from the sedimentation bin 13. This not only ensures the sealing performance of the sedimentation bin 13, ensuring that the cooling liquid can normally deposit impurities in the sedimentation bin 13 and maintain the stable progress of the sedimentation process, but also avoids the leakage of the cooling liquid polluting the environment around the equipment or affecting other components of the equipment. At the same time, the good sealing performance also helps to maintain the stable pressure of the entire cooling liquid circulation system, so that the cooling liquid can be smoothly circulated according to the predetermined process, improving the reliability and stability of the equipment, prolonging the service life of the equipment, and ensuring the continuous and efficient operation of the numerical control machining center.

[0036] The storage device 1 further comprises a battery compartment 14 and a control panel 15, the battery compartment 14 is located on the right side of the buffer compartment 12, and a battery assembly 141 is installed inside the battery compartment 14, and an inductive power transmission line 1411 is connected to the battery assembly 141, the inductive power transmission line 1411 penetrates through the side wall of the buffer compartment 12 and is connected to the electromagnetic coil 12122 in the elastic buffer device 121.

[0037] By adopting the above technical scheme, the battery compartment 14 and the battery assembly 141 inside it provide a separate power source for the electromagnetic coil 12122 in the elastic buffer device 121, and the layout design of the battery compartment 14 on the right side of the buffer compartment 12 is reasonable, which does not affect the functions of other parts of the storage device 1, and can be easily connected with the elastic buffer device 121. The battery assembly 141 is connected to the electromagnetic coil 12122 through the inductive power transmission line 1411, and the design of the inductive power transmission line 1411 penetrating through the side wall of the buffer compartment 12 ensures that the electric energy can be stably transmitted to the electromagnetic coil 12122. During the operation of the equipment, when the electromagnetic adsorption function needs to be started to remove metal debris and other impurities in the cooling liquid, the battery assembly 141 supplies power to the electromagnetic coil 12122 to generate a magnetic field, so that the adsorption core 1212 plays an adsorption role. This independent power supply mode makes the electromagnetic adsorption function not affected by the fluctuation of external power supply, ensuring the stability and reliability of the adsorption effect. At the same time, the operator can monitor and adjust the power supply state of the battery assembly 141 and the operating parameters of the whole equipment through the control panel 15, realizing the intelligent control of the equipment, improving the convenience and flexibility of the equipment operation, and helping to improve the overall performance and working efficiency of the cooling liquid circulating equipment of the numerical control machining center.

[0038] The cooling device 2 further comprises a water pump compartment 22, the water pump compartment 22 is located on the lower side of the cooling device 2, and a second water pump 221 is installed in the water pump compartment 22, and a circulating water pipe 2211 is connected to the second water pump 221, one end of the circulating water pipe 2211 is communicated with the second water pump 221, and the other end is fixedly installed on the water inlet end of the machining center 3.

[0039] By adopting the above technical scheme, the water pump compartment 22 in the cooling device 2 provides a stable mounting position for the second water pump 221, and the layout of the cooling device 2 at the lower side helps to optimize the overall structure of the equipment, so that the center of gravity of the equipment is more stable, and the connection and maintenance with other components are facilitated. The second water pump 221 in the water pump compartment 22 is one of the key power components of the cooling liquid circulation, which is connected in communication with the water inlet end of the machining center 3 through the circulating water pipe 2211. When the second water pump 221 is started, it can draw the cooling liquid cooled by the heat exchange compartment 21 from the cooling device 2 and stably deliver it to the water inlet end of the machining center 3 through the circulating water pipe 2211, which ensures that the machining center 3 has sufficient supply of cooling liquid during machining, realizes efficient recycling of the cooling liquid, and the one end of the circulating water pipe 2211 is connected in communication with the second water pump 221, which ensures that the cooling liquid can smoothly enter the circulating water pipe from the water pump, and the other end is fixedly installed at the water inlet end of the machining center 3. This design makes the circulation path of the cooling liquid in the equipment clear and orderly, ensures the stable operation of the entire cooling liquid circulation system, helps to improve the machining accuracy of the machining center 3 and the service life of the equipment, and improves the utilization efficiency of the cooling liquid, reduces the waste of the cooling liquid, and reduces the production cost.

[0040] The bottom of the funnel 131 is conical, and a leakage hole 1311 is formed at the tip of the cone. The diameter of the leakage hole 1311 is smaller than the diameter of the top opening of the funnel 131.

[0041] By adopting the above technical scheme, the conical design of the bottom of the funnel 131 utilizes the principle of gravity, so that the impurities carried by the cooling liquid during the natural falling process in the sedimentation compartment 13 are more easily accumulated at the tip of the cone under the action of gravity. This shape can effectively guide the sedimentation direction of the impurities and improve the sedimentation efficiency. The diameter of the leakage hole 1311 formed at the tip of the cone is smaller than the diameter of the top opening, which can control the discharge speed of the impurities on the one hand, prevent the impurities from being discharged too quickly without sufficient sedimentation, and ensure the sedimentation effect; on the other hand, the smaller diameter of the leakage hole 1311 can reduce the possibility of the cooling liquid flowing out with the impurities, further ensuring the purity of the cooling liquid. During the operation of the equipment, the cooling liquid flows from the upper part of the sedimentation compartment 13, and the impurities gradually sediment in the funnel 131 to the tip of the cone. When the impurities need to be cleaned, the closed door 133 at the bottom of the sedimentation compartment 13 can be opened to discharge the impurities accumulated near the leakage hole 1311 at the tip of the cone. The operation is convenient and efficient. This design helps to prolong the service life of the cooling liquid and reduce the damage of the impurities to the subsequent equipment components (such as the heat exchange water pipe 211 in the cooling device 2, the water pump, etc.), thereby ensuring the stable operation of the entire cooling liquid circulation equipment and improving the machining quality of the numerical control machining center and the overall reliability of the equipment.

[0042] The front side of the storage device 1 is provided with a control panel 15, which is electrically connected with each electronic component.

[0043] According to the technical scheme, the control panel 15 on the front side of the storage device 1 provides a convenient operation interface for the operator. Since the control panel 15 is electrically connected with each electronic component, the operator can monitor and manage the running state of the entire cooling liquid circulating device through the control panel 15. For example, the operator can check the cooling liquid temperature data monitored by the first temperature sensor 111 in the main storage bin 11 on the control panel 15, and timely adjust the running parameters of the cooling device 2 according to the temperature condition to ensure that the cooling liquid temperature is appropriate. The cooling liquid temperature in the heat exchange bin 21 fed back by the second temperature sensor 212 in the cooling device 2 can also be directly displayed on the control panel 15 so that the operator can determine whether the heat exchange effect is normal. Meanwhile, the control panel 15 can also control the power supply of the electromagnetic coil 12122 of the elastic buffer device 121 by the battery assembly 141 in the battery bin 14 to realize the opening and closing of the electromagnetic adsorption function and flexibly control the adsorption operation of the adsorption core 1212 on the metal scraps and other impurities in the cooling liquid. In addition, through the control panel 15, the operator can conveniently obtain the working information of each part of the device, such as the running state of the water pump and the opening and closing condition of each valve. When the device is abnormal, the control panel 15 can display the corresponding fault alarm information to help the operator quickly locate the problem and take effective measures to solve the problem.
