Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment for CNC machine tool processing, specifically a dust removal mechanism for CNC machine tool processing. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. CNC machine tools can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. CNC machine tools generate a large amount of debris and dust during machining. Working in environments with high dust levels can easily lead to occupational diseases such as pneumoconiosis for machining workers. Therefore, a dust removal device is needed for CNC machine tool machining.

[0003] Existing dust removal mechanisms for CNC machine tool processing often rely on dust filter plates to filter the collected dust and prevent it from spreading to the outside environment. However, after long-term processing, a lot of dust will adhere to the surface of the dust filter plate. In order to ensure the ventilation and dust collection effect, the dust filter plate usually needs to be cleaned. However, in order to avoid the spread of dust during replacement, the machine usually needs to be stopped to disassemble and clean the dust filter plate. This process consumes a lot of time and effort, thus reducing processing efficiency. To address this, we propose a dust removal mechanism for CNC machine tool processing. Utility Model Content

[0004] The main objective of this invention is to provide a dust removal mechanism for CNC machine tool processing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal mechanism for CNC machine tool processing, comprising a machine tool body, and the machine tool body includes a base, a slide, and a processing component. The slide is slidably disposed on both sides of the base, and the processing component is disposed inside the slide. A dust filter box is detachably connected to the back of the machine tool body. Ventilation tubes are nested and interconnected on both sides of the upper surface of the dust filter box. A fan is detachably connected to the inner cavity of the ventilation tube. Dust suction hoses are interconnected on both bottom ends of the dust filter box. Electric telescopic rods are detachably connected to the outer walls of both bottom ends of the slide. Dust suction hoods are provided on the inner sides of both bottom ends of the slide, and one side of the back of the dust suction hood is detachably connected to the telescopic end of the electric telescopic rod. The air outlet of the dust suction hood and the air inlet of the dust suction hose are interconnected. A guide component is provided at the upper end of the inner cavity of the dust filter box. A partition plate is fixedly connected at the center of the inner cavity of the dust filter box above the guide component. Dust filter plates are detachably snapped onto both sides of the partition plate.

[0006] Preferably, the guiding assembly includes a fixed sleeve, a transmission rod, and a guide plate. The transmission rod is rotatably mounted in the dust filter box cavity below the partition plate. The fixed sleeve is detachably mounted on the surface of the transmission rod. The guide plate is fixedly connected to the lower surface of the fixed sleeve, and the top end of the fixed sleeve is in contact with the bottom end of the partition plate.

[0007] Preferably, a servo motor is detachably nested on the outer wall of the dust box at a corresponding position on one side of the transmission rod, and the power output end of the servo motor is fixedly connected to one side of the transmission rod through a coupling. The lower inner wall of the dust box cavity is provided with a limiting groove that matches the guide plate.

[0008] Preferably, the inner wall of the dust box and the surface of the partition plate at corresponding positions on both sides of the dust filter plate are provided with snap-fit ​​components. The snap-fit ​​components include snap-fit ​​grooves, hydraulic damping rods, springs and limiting plates. The snap-fit ​​grooves are opened at corresponding positions on the inner wall of the dust box and the surface of the partition plate. The side of the snap-fit ​​groove facing the dust filter plate is detachably connected to the hydraulic damping rod. The surface of the hydraulic damping rod is surrounded by a spring. The inner side of the hydraulic damping rod is detachably connected to the limiting plate.

[0009] Preferably, the outer wall surface of the dust filter plate is provided with a hand-pull groove.

[0010] Preferably, a collection frame is detachably connected to the bottom of the inner cavity of the dust filter box.

[0011] Preferably, the surface of the dust filter box is equipped with a control panel, and the electric telescopic rod, servo motor and fan are all electrically connected to an external power source through the control panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes a partition plate, a dust filter, a servo motor, a transmission rod, a guide plate of a fixed sleeve, and limiting grooves on both sides of the bottom of the dust filter box that are compatible with the guide plate. The partition plate divides the upper part of the dust filter box into two sets of filtration chambers. Simultaneously, the servo motor drives the transmission rod to rotate to one side, causing the fixed sleeve and guide plate on its surface to move synchronously to the same side, so that their bottom ends fit with the tops of the limiting grooves on both sides of the bottom of the dust filter box, thereby sealing one side of the dust filter chamber. During filtration, the dust is filtered through the filter plate in the dust filter box on the opposite side. When cleaning is required, the servo motor is reversed, which drives the guide plate to rotate to the bottom of the other side of the dust filter chamber. At the same time, the dust filter chamber that was originally in working state switches to maintenance state, and the unused dust filter plate on the other side is put into filtration. During this process, the operator can remove the used dust filter plate from the snap-fit ​​position for cleaning or replacement. The entire maintenance process does not require machine downtime, effectively ensuring the continuous operation of the CNC machine tool and improving production efficiency.

[0014] 2. This utility model utilizes a dust filter plate, a snap-fit ​​groove, a hydraulic damping rod, a spring, and a limiting plate in cooperation. The dust filter plate slides directly into the snap-fit ​​groove from the opening. At this time, the hydraulic damping rod and the spring press the limiting plate inward, ensuring that the dust filter plate is securely engaged and stable during dust filtration. This prevents the dust filter plate from loosening due to equipment vibration. When the dust filter plate needs to be replaced, the hand-pull groove on the outside of the dust filter plate is pulled to overcome the resistance of the hydraulic damping rod and the spring, allowing the dust filter plate to be easily removed. The operation is simple and quick, effectively improving the efficiency of dust filter plate disassembly and assembly, facilitating rapid cleaning, and enhancing ease of use. It is also convenient for use with machine tools for dust removal. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Example

[0021] Please see Figure 1 - Figure 3The figure shows a dust removal mechanism for CNC machine tool processing, including a machine tool body 1. The machine tool body 1 includes a base, a slide 2, and a processing assembly. The slide 2 is slidably disposed on both sides of the base, and the processing assembly is disposed inside the slide 2. A dust filter box 6 is detachably connected to the back of the machine tool body 1. Ventilation cylinders 8 are nested and interconnected on both sides of the upper surface of the dust filter box 6. A fan 9 is detachably connected to the inner cavity of the ventilation cylinder 8. Dust suction hoses 4 are interconnected on both bottom ends of the dust filter box 6. Electric telescopic rods 5 are detachably connected to the outer walls of both bottom ends of the slide 2. Dust suction hoods 3 are provided on the inner sides of both bottom ends of the slide 2, and one side of the back of the dust suction hood 3 is connected to the telescopic end of the electric telescopic rod 5. The dust collection hood 3 and the dust collection hose 4 are detachably connected. The upper end of the dust collection box 6 is equipped with a guide component. A partition plate 12 is fixedly connected to the center of the dust collection box 6 above the guide component. Dust filter plates 11 can be detachably snapped onto both sides of the partition plate 12. The electric telescopic rod 5 can adjust the position of the dust collection hood 3 in real time according to the position of the processing component to ensure that the dust collection hood 3 is accurately aligned with the dust source, which greatly improves the dust collection efficiency. The guide component and the partition plate 12 in the dust collection box 6 cooperate with each other to flexibly switch the filter chamber during the dust filtration process, which makes it convenient to clean and replace the dust filter plate 11 without interrupting the dust removal operation.

[0022] The guiding assembly includes a fixed sleeve 13, a transmission rod 14, and a guide plate 15. The transmission rod 14 is rotatably mounted in the inner cavity of the dust filter box 6 below the partition plate 12. The fixed sleeve 13 is detachably mounted on the surface of the transmission rod 14. The guide plate 15 is fixedly connected to the lower surface of the fixed sleeve 13, and the top of the fixed sleeve 13 is in contact with the bottom of the partition plate 12. A servo motor 7 is detachably nested on the outer wall of the dust filter box 6 at a corresponding position on one side of the transmission rod 14. The power output end of the servo motor 7 is fixedly connected to one side of the transmission rod 14 via a coupling. The inner wall of the lower end of the inner cavity of the dust filter box 6 is provided with a limiting groove that matches the guide plate 15. When the servo motor 7 drives the transmission rod 14 to rotate, the fixed sleeve 13 drives the guide plate 15 to move precisely under the restriction of the limiting groove, sealing one side of the dust filter chamber, so that the dust-laden airflow can only be filtered through the dust filter plate 11 of the other side of the dust filter chamber. When the dust filter plate 11 needs to be cleaned, simply reverse the servo motor 7 to quickly switch the filter chamber, and the replacement and cleaning of the dust filter plate 11 can be completed without stopping the machine.

[0023] The dust filter box 6 and the partition plate 12 are provided with snap-fit ​​components at corresponding positions on both sides of the dust filter plate 11. Each snap-fit ​​component includes a snap-fit ​​groove 10, a hydraulic damping rod 17, a spring 18, and a limiting plate 19. The snap-fit ​​groove 10 is located at the corresponding positions on the inner wall of the dust filter box 6 and the surface of the partition plate 12. A hydraulic damping rod 17 is detachably connected to the side of the snap-fit ​​groove 10 facing the dust filter plate 11. A spring 18 is arranged around the surface of the hydraulic damping rod 17. A detachable limiting plate 19 is provided on the side, and a hand-pull groove is provided on the outer wall surface of the dust filter plate 11. The dust filter plate 11 is stably installed between the inner wall of the dust filter box 6 and the partition plate 12 through the snap-fit ​​assembly. The hydraulic damping rod 17 and the spring 18 work together to buffer and effectively prevent the dust filter plate 11 from loosening due to equipment vibration. At the same time, with the help of the hand-pull groove on the outer wall of the dust filter plate 11, the resistance of the spring 18 and the hydraulic damping rod 17 can be overcome, and the dust filter plate 11 can be easily removed and installed, which greatly improves the convenience of replacing and maintaining the dust filter plate 11.

[0024] The dust filter box 6 has a detachable collection frame 16 at the bottom of its inner cavity. The surface of the dust filter box 6 is equipped with a control panel, and the electric telescopic rod 5, servo motor 7 and fan 9 are all electrically connected to an external power source through the control panel. By setting a detachable collection frame 16 at the bottom of the inner cavity of the dust filter box 6, the filtered dust is collected in a centralized manner, which facilitates subsequent cleaning. The control panel enables centralized control of each component, making operation more convenient and efficient, and improving the user experience and work efficiency of the entire dust removal mechanism.

[0025] It should be noted that this utility model is a dust removal mechanism for CNC machine tool processing. During operation, the operator slides the dust filter plate 11 into the opening of the snap-fit ​​groove 10. During the sliding process, the hydraulic damping rod 17 and spring 18 in the snap-fit ​​groove 10 press the limiting plate 19 inward to firmly lock the dust filter plate 11, ensuring its stable installation. The partition plate 12 divides the upper part of the dust filter box 6 into two sets of filter chambers. The servo motor 7 starts, driving the transmission rod 14 to rotate to one side. The fixing sleeve 13 and guide plate 15 move synchronously to the same side until the bottom end of the guide plate 15 is in contact with the top of the limiting groove on one side of the bottom of the dust filter box 6, sealing one side of the dust filter chamber. At this time, the dust-laden airflow enters from the open dust filter chamber on the other side, and after being filtered by the dust filter plate 11 in the dust filter box 6 on that side, the purified air is discharged from the dust filter box 6. During the CNC machine tool processing, the dust collection hood 3 continuously collects the dust-laden gas generated during processing and transports it to the filter chamber through the dust collection hose 4. Dust-laden gas continuously passes through the dust filter plate 11 on the open side of the dust chamber 6, maintaining a clean processing environment. When the used dust filter plate 11 needs to be cleaned or replaced, the operator operates the servo motor 7 to reverse, which drives the transmission rod 14 to rotate in the opposite direction, causing the guide plate 15 to rotate to the bottom of the dust filter chamber on the other side, sealing the dust filter chamber on that side. The dust filter chamber that was originally working is switched to the maintenance state, and the unused dust filter plate 11 on the other side is put into the filtration operation to ensure that the dust removal work is uninterrupted. In the dust filter chamber in the maintenance state, the operator pulls the hand pull groove on the outside of the dust filter plate 11 to overcome the resistance of the hydraulic damping rod 17 and the spring 18, and takes the dust filter plate 11 out of the locking groove 10 for cleaning or replacement. After the maintenance operation is completed, the new dust filter plate 11 is slid into the locking groove 10 and is securely installed with the help of the hydraulic damping rod 17, the spring 18 and the limit plate 19. The structure is simple, easy to operate, and effectively improves the convenience of use.
