Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and more specifically, to an automatic opening and closing cooling device for CNC machine tools. Background Technology

[0002] In modern manufacturing, CNC machine tools have become core processing equipment due to their advantages such as high precision and high efficiency. However, during long-term continuous processing, key components of CNC machine tools, such as the spindle, guide rails, and servo motors, generate a large amount of heat due to friction and energy loss, causing the component temperature to rise sharply. Excessive temperature not only causes thermal deformation of machine tool components, reducing machining accuracy and surface quality, but also accelerates component wear and aging, shortens the machine tool's service life, and may even lead to equipment failure, affecting production safety and continuity.

[0003] Currently, the common cooling methods for CNC machine tools are air cooling and liquid cooling. These cooling devices usually operate continuously, regardless of whether the machine tool parts are at high temperatures. This not only wastes energy and increases production costs, but also leads to increased wear and tear on the cooling devices themselves and higher maintenance costs due to long-term operation.

[0004] Patent CN117226591B discloses an automatic opening and closing cooling device for CNC machine tools, belonging to the field of CNC machine tool technology. It includes a pneumatic control mechanism and an active cooling mechanism. The pneumatic control mechanism automatically controls the opening and closing of the machine door, automatically opening it in the event of a sudden power outage. The active cooling mechanism includes a mounting base with a strip-shaped sliding member slidably connected to it, and an air blower is installed on the sliding member. This automatic opening and closing cooling device for CNC machine tools automatically controls the opening and closing of the machine door through the pneumatic control mechanism, automatically opening the door in the event of a sudden power outage to promptly cool the internal environment. Simultaneously, during the door opening process, the active cooling mechanism actively cools the internal environment. Combined with the control of the airflow path during cooling, it effectively improves the cooling speed and timeliness, thereby improving the quality and pass rate of plasticized products.

[0005] While this technical solution offers advantages such as improved cooling speed and timeliness, and enhanced quality and yield of plasticized products, the opening and closing mechanisms of most CNC machine tools are currently quite complex. For example, a motor drives a corresponding drive structure to displace the door, which then opens along the hinge. This outward rotation of the door also occupies space at the front of the machine, affecting operational convenience. Furthermore, some CNC machine tools use airflow for cooling at the door opening area. Since other parts of the machine tool lack airflow channels, directly blowing air onto the door area hinders air convection, further impacting the cooling effect. Therefore, we propose an automatic opening and closing cooling device for CNC machine tools. Utility Model Content

[0006] The purpose of this invention is to provide an automatic opening and closing cooling device for CNC machine tools to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic opening and closing cooling device for CNC machine tools includes a machine tool body. A pick-up and drop-off hole is provided on the front side of the machine tool body's housing. A cylinder is fixedly installed on the front side of the machine tool body. A door panel is detachably installed at the end of the cylinder's telescopic shaft. The door panel slides along the front side of the machine tool body and, when closed, blocks the pick-up and drop-off hole. A cooling assembly is provided on the rear side of the machine tool body. The cooling assembly includes a ventilation pipe. A rectangular box connected to the ventilation pipe is fixedly installed on the front side of the ventilation pipe. The rectangular box is fixedly installed on the rear side of the machine tool body. Multiple first air outlet pipes and multiple second air outlet pipes are fixedly installed on the front side of the rectangular box. Both the first and second air outlet pipes are located inside the machine tool body. A fan is provided at the end of each ventilation pipe.

[0009] Preferably, the bottom of the machine tool body is fixedly equipped with multiple support legs, the height of which is between 5cm and 8cm.

[0010] Preferably, two symmetrical guide rails are fixedly installed on the front side of the machine tool body housing, and the upper and lower end plates of the door panel are located in the corresponding guide rails and are slidably connected to the guide rails.

[0011] This feature guides the movement of the door panel.

[0012] Preferably, a fixing sleeve is fixedly installed at the end of the telescopic shaft of the cylinder, and a fixing plate is fixedly installed on the side of the fixing sleeve. The door panel is detachably installed on the fixing plate by a plurality of fastening screws.

[0013] This feature facilitates the installation and removal of the door panels.

[0014] Preferably, the first air outlet duct is horizontally arranged, and the second air outlet duct is inclined downward at 45° to 60°.

[0015] Preferably, an air inlet cover is fixedly installed at the air inlet end of the ventilation duct, an air inlet cylinder is fixedly installed at the end of the air inlet cover, and the fan is disposed inside the air inlet cylinder.

[0016] Preferably, an inner support ring is fixedly installed on the inner wall of the air inlet duct, and a fixing ring is fixedly installed on the fan. The fixing ring is detachably installed on the front side of the inner support ring by a plurality of fastening screws.

[0017] This setting facilitates the installation and removal of the fan.

[0018] Preferably, the air inlet flange of the air inlet duct is connected to an arc-shaped pipe, and the end of the arc-shaped pipe is oriented downwards.

[0019] This feature provides some dust protection, and the arc-shaped tube is detachable, facilitating subsequent disassembly and maintenance of the fan.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model, by setting a cylinder to drive the door panel to slide and open along the guide rail, abandons the traditional complex door panel opening and closing method of motor drive and hinge rotation, simplifies the door panel opening and closing operation process, and avoids the problem of the door panel rotating outward and occupying the space on the front side of the machine tool, greatly improving the operator's convenience; and by fastening screws to install the door panel on the fixed plate, it is convenient to disassemble and install the door panel and facilitates later maintenance.

[0022] 2. This utility model provides a cooling component consisting of a ventilation pipe, a rectangular box, a first exhaust pipe, and a second exhaust pipe, installed on the rear side of the machine tool body. Combined with a fan at the end of the ventilation pipe, it can introduce outside air into the machine tool and create good air convection within the machine tool through exhaust pipes set at different angles. Compared to the method of only blowing air to dissipate heat at the door opening and closing parts, this effectively improves the air circulation inside the machine tool, cools the inside of the machine tool from all directions, and significantly enhances the cooling effect.

[0023] 3. This utility model uses an arc-shaped pipe connected to the air inlet end of the air inlet duct, with its end opening facing downwards, which can effectively block dust and other impurities from entering the ventilation duct and the machine tool, thus playing a dustproof protection role. In addition, the arc-shaped pipe is connected by a flange, which is convenient to disassemble. Combined with the fan and the inner support ring, which can be detached by fastening screws, the disassembly and maintenance of the fan is more convenient, which is conducive to ensuring the normal operation of the cooling device and extending its service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-4 This utility model provides a technical solution: an automatic opening and closing cooling device for CNC machine tools, including a machine tool body 1. A pick-up and drop-off hole 10 is provided on the front side of the machine tool body 1. A cylinder 13 is fixedly installed on the front side of the machine tool body 1. A door panel 15 is detachably installed at the end of the telescopic shaft of the cylinder 13. The door panel 15 slides along the front side of the machine tool body 1. When the door panel 15 is closed, it is used to block the pick-up and drop-off hole 10. A fixing sleeve 131 is fixedly installed at the end of the telescopic shaft of the cylinder 13. A fixing plate 14 is fixedly installed on the side of the fixing sleeve 131. The door panel 15 is detachably installed on the fixing plate 14 by multiple fastening screws, allowing the door panel 15 to slide along the front side of the machine tool body 1. This eliminates the traditional complex opening and closing method, simplifies the operation process, reduces the space occupied by the door panel opening and closing, and improves operational convenience. The design of the fixing sleeve 131, fixing plate 14, and fastening screws facilitates the disassembly and installation of the door panel 15, making later maintenance convenient.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, a cooling component 2 is provided on the rear side of the machine tool body 1. The cooling component 2 includes a ventilation pipe 20. A rectangular box 21 connected to the ventilation pipe 20 is fixedly installed on the front side of the ventilation pipe 20. The rectangular box 21 is fixedly installed on the rear side of the machine tool body 1. Multiple first air outlet pipes 22 and multiple second air outlet pipes 23 are fixedly installed on the front side of the rectangular box 21. Both the first air outlet pipes 22 and the second air outlet pipes 23 are located inside the machine tool body 1. A fan 27 is provided at the end of the ventilation pipe 20. The first air outlet pipe 22 is set horizontally, and the second air outlet pipe 23 is set downward at a 45° to 60° angle, so as to introduce outside air into the machine tool body 1. The horizontally set first air outlet pipe 22 and the downwardly inclined second air outlet pipe 23 make the air form good convection inside the machine tool. Compared with the traditional local heat dissipation method, the cooling effect inside the machine tool is improved in all aspects.

[0034] like Figure 1 As shown, multiple support legs 11 are fixedly installed at the bottom of the machine tool body 1. The height of the support legs 11 is between 5cm and 8cm, which plays a role in providing stable support.

[0035] like Figure 1 and Figure 2 As shown, two symmetrical guide rails 12 are fixedly installed on the front side of the housing of the machine tool body 1. The upper and lower end plates of the door panel 15 are located in the corresponding guide rails 12 and are slidably connected to the guide rails 12, so that the door panel 15 slides more stably and smoothly along the guide rails 12.

[0036] In this embodiment, an air inlet cover 24 is fixedly installed at the air inlet end of the ventilation pipe 20, and an air inlet tube 25 is fixedly installed at the end of the air inlet cover 24. The fan 27 is disposed inside the air inlet tube 25, and an inner support ring 26 is fixedly installed on the inner wall of the air inlet tube 25. A fixing ring 271 is fixedly installed on the fan 27. The fixing ring 271 is detachably installed on the front side of the inner support ring 26 by multiple fastening screws, which facilitates the installation and removal of the fan 27 and makes maintenance and repair convenient.

[0037] Specifically, the air inlet flange of the air inlet duct 25 is connected to an arc-shaped pipe 28. The end of the arc-shaped pipe 28 is set downwards, which can effectively block dust and other impurities from entering and play a role in dust protection. In addition, the arc-shaped pipe 28 is detachable, which further improves the convenience of maintenance of the fan 27 and ensures the stable operation of the cooling device.

[0038] Finally, it should be noted that the cylinder 13, fan 27, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0039] When using the automatic opening and closing cooling device for CNC machine tools of this utility model, the cylinder 13 is activated, and the telescopic shaft of the cylinder 13 drives the door plate 15 to slide open along the guide rail 12. The workpiece is placed through the pick-up and put-down hole 10, and then the door plate 15 is closed to block the pick-up and put-down hole 10 for processing operations.

[0040] When heat dissipation is required, cylinder 13 controls the door panel 15 to open and starts fan 27. Outside air enters ventilation pipe 20 through arc pipe 28, air inlet duct 25, and air inlet hood 24, then flows into rectangular box 21, and finally blows into the machine tool body 1 through the horizontally set first air outlet pipe 22 and the downwardly inclined second air outlet pipe 23. The internal heat can be discharged from the pick-up and drop-off hole 10, forming good convection and achieving cooling of the machine tool.
