Description

Technical Field

[0001] This utility model belongs to the technical field of CNC vertical machining centers, and specifically relates to a heat dissipation mechanism for machining centers. Background Technology

[0002] CNC machining centers are among the most commonly used machining equipment today. They are powerful, highly automated, multi-functional machine tools integrating cutting, tapping, boring, and milling functions. They offer high machining accuracy and can meet the machining needs of various parts. During operation, machining centers generate a significant amount of heat due to the numerous internal components, requiring effective heat dissipation to ensure normal operation. Existing technologies, such as the high-efficiency heat dissipation device for vertical machining centers (patent application number CN202221937052.8), address this issue during operation. Fans are installed on both sides of the vertical machining center. One fan blade continuously draws in cool air from the outside into the interior of the vertical machining center, while the other fan blade continuously exhausts hot air from the interior of the vertical machining center to the outside. The two fan blades work together to form a cooling airflow and improve the heat dissipation effect. However, in the above solution, both heat dissipation screens are normally open. When the machining center is not in use, external dust will also adhere to the heat dissipation screens. After the mesh of the heat dissipation screens is blocked, it will easily affect the heat dissipation effect. At the same time, there is no dedicated dust cleaning mechanism, which requires manual cleaning, which is inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a heat dissipation mechanism for machining centers. When heat dissipation of the machining center is not required, the assembly frame can be closed to prevent dust from adhering to the filter plate and affecting heat dissipation. The filter plate can also be easily cleaned without additional manual cleaning, and the operation is simple and convenient.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A heat dissipation mechanism for a machining center, comprising:

[0006] The machining center body has heat dissipation vents on both its left and right sides.

[0007] The assembly frame is provided in two parts, and the two assembly frames are respectively installed inside two heat dissipation vents. A heat dissipation mechanism is installed inside the assembly frame.

[0008] The heat dissipation mechanism includes two U-shaped mounting frames, which are respectively fixedly installed on the inner walls of the front and rear sides of the assembly frame. A first cooling fan is fixedly installed inside one of the U-shaped mounting frames. A filter plate is slidably and sealed inside both U-shaped mounting frames. An opening is provided at the bottom of the assembly frame, and a dust collection component is provided inside the opening. A sliding groove is provided on the top side of the U-shaped mounting frame away from the machining center body. A sealing plate is slidably and sealed inside the sliding groove. An assembly block is fixedly installed on the top of the sealing plate. An extension plate is fixedly installed on the bottom of the assembly block. The lower end of the extension plate extends into the assembly frame, and a fixing block is fixedly installed on its end face. A cleaning brush is fixedly installed on the side of the fixing block near the filter plate, and one side of the cleaning brush abuts against the filter plate. An electric push rod is fixedly installed on the rear side of the assembly frame, and a drive plate is fixedly installed on the rear side of the assembly block. The telescopic end of the electric push rod is fixedly connected to the bottom of the drive plate.

[0009] As a preferred technical solution, the ash collection assembly includes a collection box, which is slidably assembled inside the opening. The bottom of the filter plate abuts against one side of the top of the collection box. The upper parts of the front and rear sides of the collection box are provided with mounting grooves. The inner walls of the front and rear sides of the opening are provided with locking grooves that match the positions of the mounting grooves. Locking components are provided inside both mounting grooves.

[0010] As a preferred technical solution, the locking assembly includes a locking block, which is slidably fitted inside the mounting groove. One end of the locking block extends into the locking groove. An inclined surface is provided on the upper part of the side of the locking block near the locking groove. A spring is fixedly installed on the side of the locking block away from the locking groove. One end of the spring is fixedly connected to the inner wall of the mounting groove.

[0011] The assembly frame has a toggle groove in the middle of both the front and rear sides. A toggle block is slidably assembled inside each of the two toggle grooves. Pull ropes are fixedly installed on the side of each of the two locking blocks that are close to each other. One end of each pull rope is fixedly connected to the upper side of the two toggle blocks.

[0012] As a preferred technical solution, a second cooling fan is fixedly installed inside another U-shaped mounting frame, and both the first and second cooling fans are located between the two filter plates.

[0013] The beneficial effects of this utility model are:

[0014] 1. High heat dissipation efficiency: The first cooling fan blows air inward and the second cooling fan exhausts air outward, forming a directional convection circulation. With the left and right assembly frames serving as air inlets and outlets respectively, the efficiency of hot air exchange inside the machining center is significantly improved, enhancing the heat dissipation effect.

[0015] 2. Automatic cleaning function: After each heat dissipation, the electric push rod resets and drives the cleaning brush to automatically clean the dust on the surface of the filter plate, eliminating the need for manual cleaning, reducing maintenance workload, and ensuring the air permeability of the filter plate.

[0016] 3. Excellent dustproof sealing: When not in operation, the sealing plate completely seals the assembly frame. Combined with the sealing strip between the filter plate and the U-shaped mounting frame, it can effectively prevent external dust from entering the machining center and protect precision components.

[0017] 4. Easy to install and disassemble: The collection box can be quickly installed and disassembled through locking components, and dust can be cleaned without tools; the filter plate adopts a sliding assembly design, which can be directly replaced after removing the collection box, making the operation simple and efficient.

[0018] 5. Stable and reliable structure: The filter plate is double-fixed by a U-shaped mounting frame and a collection box, which has a damping effect when sliding to prevent loosening; the locking component of the collection box provides continuous locking force through springs, making it firmly fixed and not easy to fall off.

[0029] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-8 As shown, a heat dissipation mechanism for a machining center according to this utility model includes...

[0031] The machining center body 1 has heat dissipation vents 11 on both the left and right sides.

[0032] There are two assembly frames 2, which are respectively installed inside the two heat dissipation vents 11. A heat dissipation mechanism is installed inside the assembly frame 2.

[0033] The heat dissipation mechanism includes two U-shaped mounting frames 23, which are fixedly installed on the inner walls of the front and rear sides of the assembly frame 2, respectively. A first cooling fan 231 is fixedly installed inside one of the U-shaped mounting frames 23. A filter plate 24 is slidably and sealed inside both U-shaped mounting frames 23. An opening is provided at the bottom of the assembly frame 2, and a dust collection component is provided inside the opening. A groove 25 is provided on the top side of the U-shaped mounting frame 23 away from the machining center body 1. A sealing plate 26 is slidably and sealed inside the groove 25. An assembly block 27 is fixedly installed on the top of the sealing plate 26. The bottom of the assembly block 27... An extension plate 28 is fixedly installed on the assembly frame 2. The lower end of the extension plate 28 extends into the assembly frame 2 and a fixing block 29 is fixedly installed on its end face. A cleaning brush 291 is fixedly installed on the side of the fixing block 29 near the filter plate 24. One side of the cleaning brush 291 abuts against the filter plate 24. An electric push rod 292 is fixedly installed on the rear side of the assembly frame 2. A drive plate 293 is fixedly installed on the rear side of the assembly block 27. The telescopic end of the electric push rod 292 is fixedly connected to the bottom of the drive plate 293. The electric push rod 292 and its matching power components are installed using existing technology to achieve control of the telescopic end of the electric push rod 292.

[0034] The electric push rod 292 is electrically connected to the control end of the machining center body 1. In the initial state, when the machining center body 1 is not in use, the sealing plate 26 completely seals the assembly frame 2, preventing external dust from entering the assembly frame 2. The extension plate 28 is also connected to the assembly frame 2 by a sliding seal. The cleaning brush 291 is located on the bottom inside the assembly frame 2. A sealing strip is installed at the connection between the filter plate 24 and the two U-shaped mounting frames 23. The elastic sealing strip has a certain elasticity, which provides a certain damping effect for the sliding between the filter plate 24 and the two U-shaped mounting frames 23. When the dust collection assembly is removed, the filter plate 24 will not fall down. When the filter plate 28 is fixed inside the machined center body 1, the operator starts the electric push rod 292. The telescopic end of the electric push rod 292 pushes the drive plate 293 upward, and the drive plate 293 drives the assembly block 27 upward. At the same time, the assembly block 27 drives the cleaning brush 291 and the sealing plate 26 upward, and the assembly frame 2 opens. Then the operator starts the first cooling fan 231. The first cooling fan 231 blows the outside air into the machined center body 1 for heat dissipation. The dust is filtered by the filter plate 26. After the two assembly frames 2 are opened, one side is the air inlet and the other side is the air outlet, which facilitates air circulation and has a good heat dissipation effect.

[0035] When no longer needed, the telescopic end of the control electric push rod 292 returns to its original state, which in turn drives the sealing plate 26 downward to re-close the assembly frame 2. The cleaning brush 291 will then move downward again, cleaning the filter plate 24 after use and sweeping the dust into the dust collection component for dust collection. This way, cleaning is performed after each use, eliminating the need for manual cleaning by staff. The operation is simple and convenient. The dust collection component can be disassembled for dust removal afterward.

[0036] The ash collection assembly includes a collection box 3, which is slidably assembled inside the opening. The bottom of the filter plate 24 abuts against one side of the top of the collection box 3. The upper part of the front and rear sides of the collection box 3 is provided with mounting grooves 32. The inner walls of the front and rear sides of the opening are provided with locking grooves 321 that match the position of the mounting grooves 32. Locking components are provided inside the two mounting grooves 32.

[0037] When the locking assembly is used for locking, the position of the collection box 3 is fixed. When cleaning the filter plate 24, the cleaned dust will enter the collection box 3 for collection. When the collection box 3 needs to be disassembled, the locking assembly is disassembled, and then the collection box 3 can be removed. After the collection box 3 is disassembled, when the filter plate 24 needs to be disassembled or replaced, the filter plate 24 can be pulled down to remove the filter plate directly. The operation is simple and convenient. During subsequent installation, the filter plate 24 is aligned with the two U-shaped mounting frames 23 and inserted upwards. After the collection box 3 is installed, the position of the filter plate 24 is also fixed.

[0038] The locking assembly includes a locking block 33, which is slidably fitted inside the mounting groove 32. One end of the locking block 33 extends into the locking groove 321. An inclined surface 34 is provided on the upper part of the side of the locking block 33 near the locking groove 321. A spring 35 is fixedly installed on the side of the locking block 33 away from the locking groove 321. One end of the spring 35 is fixedly connected to the inner wall of the mounting groove 32.

[0039] The assembly frame 2 has a toggle groove 36 in the middle of both the front and rear sides. A toggle block 362 is slidably installed inside each of the two toggle grooves 36. Pull ropes 363 are fixedly installed on one side of each of the two locking blocks 33, and one end of each pull rope 363 is fixedly connected to the upper side of the two toggle blocks 362 respectively.

[0040] In the initial state, the two springs 35 push a portion of the two locking blocks 33 out of the mounting slots 32. When the collection box 3 needs to be installed, the collection box 3 is inserted upward into the opening. Since the two locking blocks 33 are provided with inclined surfaces, when they come into contact with the port of the opening, an inward pushing force is generated, which pushes the two locking blocks 33 into the mounting slots 32 until the two mounting slots 32 are aligned with the two locking slots 321. The two springs 35 push the two locking blocks 33 into the two locking slots 321 to complete the locking. This completes the fixation of the collection box 3. No additional operation is required. The operation is simple and quick, and the fixation is effective. When disassembling later, the two actuating blocks 362 are pushed downward at the same time. The two actuating blocks 362 drive the two pull ropes 363 to move. The pull ropes 363 generate a pulling force to pull the two locking blocks 33 into the two mounting slots 32 at the same time. The operation is simple and convenient. In this way, the assembly frame 2 can be removed.

[0041] Another U-shaped mounting frame 23 has a second cooling fan 232 fixedly installed inside. Both the first cooling fan 231 and the second cooling fan 232 are located between the two filter plates 24.

[0042] The first cooling fan 231 blows air inward, while the second cooling fan 232 blows air in the opposite direction to the first cooling fan 231, which is to exhaust air outward. This increases the directional convection circulation of air and enhances the heat dissipation effect.

[0043] The device is used as follows:

[0044] When the machining center body 1 is not in use, the sealing plate 26 is in a state of completely sealing the assembly frame 2. When it is necessary to dissipate heat inside the machining center body 1, the electric push rod 292 is activated by the machining center controller. The telescopic end of the electric push rod 292 pushes the drive plate 293 upward, and the drive plate 293 drives the assembly block 27 upward. The assembly block 27 simultaneously drives the sealing plate 26 and the cleaning brush 291 to move upward, and the assembly frame 2 opens. Then the first cooling fan 231 and the second cooling fan 232 are activated. The first cooling fan 231 blows air inward and the second cooling fan 232 exhausts air outward, forming directional convection. The outside air enters the interior of the machining center body 1 after being filtered by the filter plate 24, while the hot air inside is discharged.

[0045] When not in use, the telescopic end of the electric push rod 292 is reset by the controller, which drives the sealing plate 26 to move downward to reseal the assembly frame 2. During this process, the cleaning brush 291 slides downward in sync to clean the dust attached to the surface of the filter plate 24. The dust falls into the collection box 3 of the dust collection component.

[0046] When it is necessary to clean the dust inside the collection box 3, simultaneously move the two actuating blocks 362 downwards. The actuating blocks 362 pull the locking block 33 through the pull rope 363, compressing the spring 35 and retracting it into the mounting groove 32, thus releasing the locking of the collection box 3. The collection box 3 can then be removed from the opening for cleaning. After cleaning, the collection box 3 is reinserted into the opening. Under the guidance of the inclined surface 34, the locking block 33 is first pushed into the mounting groove 32. When the mounting groove 32 is aligned with the locking groove 321, the spring 35 pushes the locking block 33 into the locking groove 321, thus fixing the collection box 3.

[0047] If the filter plate 24 needs to be replaced, after removing the collection box 3, pull the filter plate 24 directly downwards, replace it with a new filter plate 24 and insert it between the two U-shaped mounting frames 23, and then install the collection box 3 to fix the filter plate 24.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
