Description

Technical Field

[0001] The utility model belongs to the technical field of servo controllers, and particularly relates to a servo controller for a numerically controlled machine tool. Background Art

[0002] In the precise operation process of a numerically controlled machine tool, the servo controller plays a crucial role. Its operating stability and heat dissipation efficiency have a profound impact on the overall performance and operating efficiency of the machine tool. To prevent the servo controller from accidentally inhaling the hot air discharged by adjacent equipment, an existing design, such as a servo driver for a machine tool disclosed in the Chinese utility model patent document with the publication number CN219679111U, adopts a strategy of cleverly staggering the intake grille and the exhaust grille. Although this design reduces the phenomenon of hot air reflux to a certain extent, in actual applications, especially when the servo controllers are arranged quite compactly and the surrounding air circulation is poor, it is still difficult to completely avoid the risk of hot air being re-inhaled. In this case, the working environment of the servo controller may deteriorate, thereby affecting its working efficiency and service life, showing the limitations of this design in dealing with complex environments.

[0003] Therefore, it is very necessary to invent a servo controller for a numerically controlled machine tool. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a servo controller for a numerically controlled machine tool, which includes a servo controller main body, an air outlet grille, a heat dissipation component, and a centralized radiator. A heat dissipation cover of the heat dissipation component is fixedly installed outside the air outlet grille arranged above each servo controller main body. The cover plate of the heat dissipation component is fixed to one of the hot air inlet pipes of the centralized radiator. The centralized radiator includes a hot air integration box, a telescopic pipe, a heat dissipation plate, and an exhaust fan. A number of hot air integration boxes are provided. Two hot air integration boxes are connected through the telescopic pipe. The hot air integration box is provided with a pair of hot air inlet pipes. The telescopic pipe installed on one hot air integration box is fixed to the heat dissipation plate, and the exhaust fan corresponding to the telescopic pipe is installed on the heat dissipation plate.

[0005] Preferably, an intake grille is arranged on the side of the servo controller main body. An intake cover is arranged outside the intake grille and is fixedly installed on the surface of the servo controller main body. A filter component is arranged on the intake cover.

[0006] Preferably, the heat dissipation component includes a heat dissipation fan and a filter. The heat dissipation fan is fixedly installed below the cover plate and inside the heat dissipation cover. The filter fixedly installed on the cover plate is located above the heat dissipation fan. The heat dissipation fan, the filter, and the telescopic pipe are on the same vertical line.

[0007] Preferably, the centralized radiator further includes a fixing rod and a partition board. One end of the fixing rod is fixedly installed on one of the hot gas integration boxes, and the other end is fixedly installed with a heat dissipation plate. A partition board is fixedly installed in each hot gas integration box. The partition board is used to divide the inside of the hot gas integration box into two independent cavities, and each cavity is respectively communicated with a set of hot gas inlet pipes.

[0008] Preferably, a sealing cover is installed on the hot gas inlet pipe that is not connected to the heat dissipation component, and it is used to seal the hot gas inlet pipe.

[0009] Preferably, the external air flow sequentially passes through the filter component of the air inlet hood, the air inlet grille, the inside of the servo controller main body, and enters the centralized radiator after passing through the heat dissipation component.

[0010] Preferably, the telescopic pipe is a telescopic corrugated pipe, and the telescopic pipes are respectively communicated with the two cavities arranged inside the hot gas integration box.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model combines the high-efficiency heat dissipation design with the optimized utilization of hot gas circulation, significantly improving the performance of the servo controller. By integrating the air outlet grille, the heat dissipation component and the centralized radiator, a complete heat dissipation channel is formed. The hot gas is discharged from the inside of the servo controller main body through the air outlet grille, and after the preliminary heat dissipation of the heat dissipation component, it is deeply cooled by the centralized radiator and finally discharged. The centralized radiator adopts the design of hot gas integration box and telescopic corrugated pipe, which can uniformly collect and process the hot gas of multiple servo controllers. The partition board arranged inside the hot gas integration box divides the cavity into two independent parts, respectively corresponding to a set of hot gas inlet pipes, realizing the orderly flow and efficient utilization of hot gas, avoiding the external diffusion of hot air, collecting the hot air of multiple servo controller main bodies together and then discharging them together, avoiding the hot air accumulated between the servo controller main bodies. In addition, the design of the telescopic corrugated pipe enables the hot gas to be flexibly transferred between the hot gas integration boxes, further improving the heat dissipation efficiency. In addition, this design also endows the servo controller with stronger adaptability and flexibility, and can adjust the length and shape of the telescopic pipe according to actual needs to adapt to different installation environments and heat dissipation requirements, facilitating installation and use in various numerical control machine tools.

[0020] As shown in Figure 1 to Figure 3 the attached drawings:

[0021] A servo controller for a numerically controlled machine tool provided by the utility model includes a servo controller main body 1, an air outlet grille 2, a heat dissipation component 3, and a centralized radiator 4. A heat dissipation cover 31 of the heat dissipation component 3 is fixedly installed outside the air outlet grille 2 provided above each servo controller main body 1. A cover plate 32 of the heat dissipation component 3 is fixed to one of the hot air inlet pipes 42 of the centralized radiator 4. The centralized radiator 4 includes a hot air integration box 41, a telescopic pipe 43, a heat dissipation plate 44, and an exhaust fan 45. A plurality of hot air integration boxes 41 are provided. Two of the hot air integration boxes 41 are connected through the telescopic pipe 43. The hot air integration box 41 is provided with a pair of hot air inlet pipes 42 in each group. One of the telescopic pipes 43 installed on the hot air integration box 41 is fixed to the heat dissipation plate 44. An exhaust fan 45 corresponding to the telescopic pipe 43 is installed on the heat dissipation plate 44.

[0022] Furthermore, an air inlet grille 5 is added to the side of the servo controller main body 1 to introduce fresh air from the outside for auxiliary heat dissipation. To further improve the air inlet efficiency and protect the internal components from dust intrusion, an air inlet cover 6 is fixedly installed on the surface of the servo controller main body 1 and covers the air inlet grille 5. The air inlet cover 6 is specially equipped with a filter component, which can effectively filter out impurities and particulate matters in the air.

[0023] Furthermore, the heat dissipation component 3 includes a heat dissipation fan 33, and a filter screen 34 is also added to the cover plate 32. The heat dissipation fan 33 is cleverly installed inside the heat dissipation cover 31 and below the cover plate 32, while the filter screen 34 is located above the heat dissipation fan 33. This layout ensures that the hot air can undergo double filtration and heat dissipation treatment before being discharged. It should be noted that the heat dissipation fan 33, the filter screen 34, and the telescopic pipe 43 are on the same vertical line, forming a smooth heat dissipation channel.

[0024] Furthermore, the addition of a fixing rod 46 to the centralized radiator 4 enables the heat dissipation plate 44 to be firmly connected to the hot air integration box 41, enhancing the stability of the overall structure. Secondly, a partition plate 47 is installed inside each hot air integration box 41. This design cleverly divides the cavity into two independent parts, and each part corresponds to a group of hot air inlet pipes 42 respectively, realizing the orderly management and efficient heat dissipation of the hot air.

[0025] Furthermore, in order to further improve the efficiency and safety of the heat dissipation system, a sealing cover 48 is installed on the hot air inlet pipe 42 that is not connected to the heat dissipation component 3. This design can not only effectively prevent hot air leakage and the entry of external impurities, but also conveniently open or close the hot air inlet pipe 42 when needed to meet different heat dissipation requirements.

[0026] Furthermore, in the overall design, an efficient heat dissipation path for the external airflow is carefully planned. The airflow first passes through the filter assembly of the air intake hood 6 for preliminary filtration, and then enters the interior of the servo controller main body 1 through the air intake grille 5. After heat exchange is completed inside the servo controller main body 1, the hot air is guided to the heat dissipation assembly 3 for further heat dissipation treatment, and finally enters the centralized radiator 4 through the telescopic pipe 43 for in-depth heat dissipation and discharge.

[0027] Furthermore, the telescopic pipe 43 adopts a telescopic bellows design, which endows it with extremely high flexibility and adaptability. The telescopic pipe 43 can not only adjust its length and shape according to actual needs, but also achieve seamless connection with the two cavities provided inside the hot air integration box 41, ensuring smooth transfer of hot air and efficient heat dissipation.

[0028] The working principle is as follows: First, when the CNC machine tool servo controller starts to work, the electronic components inside the servo controller main body 1 generate heat. To effectively dissipate this heat, fresh air from the outside air intake hood 6 is introduced. The filter assembly can filter out dust and impurities in the air, ensuring that the airflow entering the servo controller main body 1 is clean. Then, the preliminarily filtered air enters the interior of the servo controller main body 1 through the air intake grille 5. Here, the air exchanges heat with the heat elements inside the servo controller main body 1, absorbs heat and becomes hot air.

[0029] Next, this hot air is guided to the air outlet grille 2 above the servo controller main body 1. The heat dissipation cover 31 of the heat dissipation assembly 3 is fixedly installed outside the air outlet grille 2, and the hot air enters the heat dissipation assembly 3 through the heat dissipation cover 31. Inside the heat dissipation assembly 3, the hot air first encounters the filter screen 34 above the cover plate 32. The filter screen 34 performs secondary filtration on the hot air to remove the tiny particles that may be carried in it. Then, the filtered hot air is blown by the heat dissipation fan 33. The rotation of the heat dissipation fan 33 generates wind power, accelerating the flow of the hot air and taking away more heat. In this way, the hot air is preliminarily heat-dissipated inside the heat dissipation assembly 3.

[0030] Next, the hot air after preliminary heat dissipation enters the centralized radiator 4 through the part where the cover plate 32 of the heat dissipation assembly 3 is connected to one of the hot air inlet pipes 42 of the centralized radiator 4. The centralized radiator 4 includes a hot air integration box 41, a telescopic pipe 43, a heat dissipation plate 44, and an exhaust fan 45. A partition 47 is installed inside the hot air integration box 41 to divide the cavity into two independent parts, and each part corresponds to a group of hot air inlet pipes 42 respectively. In this way, the hot air is orderly managed and distributed into different hot air integration boxes 41.

[0031] Then, the hot air is connected through the telescopic pipe 43 between the two hot air integration boxes 41. The telescopic pipe 43 is designed with a telescopic corrugated pipe, which can adjust the length and shape according to actual needs to ensure the smooth transmission of the hot air. The hot air finally enters the heat dissipation plate 44 through the telescopic pipe 43 installed on one of the hot air integration boxes 41. On the heat dissipation plate 44, the hot air is further heat-dissipated. An exhaust fan 45 corresponding to the telescopic pipe 43 is installed on the heat dissipation plate 44. The rotation of the exhaust fan 45 generates a strong wind force, blowing the hot air away from the heat dissipation plate 44 and dissipating the heat into the air through the heat dissipation effect of the heat dissipation plate. Finally, the hot air after deep heat dissipation treatment is discharged into the external environment, completing the entire heat dissipation process. At the same time, a sealing cover 48 is installed on the hot air inlet pipe 42 that is not connected to the heat dissipation component 3, effectively preventing hot air leakage and the entry of external impurities, ensuring the efficiency and safety of the heat dissipation system.

[0032] Any technical solution using the technical solution of the present utility model, or a technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects, shall fall within the protection scope of the present utility model.
