Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a spindle dust collection device. Background Technology

[0002] In the field of machining, when a spindle drives a cutting tool to cut a workpiece, a large amount of metallic or non-metallic dust is generated. For example, during graphite machining, due to the porous nature of graphite, a large amount of extremely fine graphite dust is produced during the cutting process. This dust has a strong adsorption capacity, easily adhering to various parts of the machine tool, and diffuses rapidly. If not collected in time, it will cause serious pollution to the machining environment, and long-term inhalation will cause great harm to the respiratory system of operators. At the same time, graphite dust entering the machine tool may cause problems such as short circuits and component wear, significantly reducing the service life of the equipment and machining accuracy.

[0003] Currently, machining often involves different cutting methods such as planar milling, deep groove cutting, and curved surface machining. The dust generated by these methods has different diffusion directions and ranges, making it difficult for general dust collection devices to achieve targeted and efficient collection. To improve dust collection efficiency, some devices are equipped with jet structures that use airflow to blow up dust and enhance the negative pressure suction effect. However, the nozzle angle of existing jet structures is generally fixed or can only be adjusted to a limited angle, making it impossible to flexibly adjust according to the relative position of the tool and workpiece or the specific location of the cutting point during machining. During machining, dust easily accumulates in fine areas such as the contact edge between the tool and workpiece and inside deep grooves. The airflow of existing jet structures cannot accurately act on these areas, making it difficult for dust to be blown up and sucked into the dust collection device, thus affecting the overall dust collection efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spindle dust collection device.

[0005] The objective of this utility model can be achieved through the following technical solution: A spindle dust collection device includes a dust collection box and a dust collection hood connected to the dust collection box. The dust collection hood is provided with an exhaust port. The dust collection box is provided with an installation structure for adapting to the spindle. The dust collection box is also provided with an air distribution manifold. At least one connecting seat is connected to the air distribution manifold. One end of the connecting seat has a first mounting cavity communicating with the air distribution manifold. A first ball head is movably disposed in the first mounting cavity. A first fixing sleeve for locking the first ball head is threadedly connected to the outside of the first mounting cavity. A nozzle communicating with the first mounting cavity is provided on the first ball head. A nozzle assembly that can be adjusted at multiple angles is connected to the end of the nozzle away from the first ball head, and the nozzle assembly is communicating with the inside of the nozzle.

[0006] Preferably, the nozzle assembly includes a support and a connecting pipe. One end of the support has a second mounting cavity, and the other end has a nozzle communicating with the second mounting cavity. One end of the connecting pipe is connected to the nozzle pipe, and the other end has a second ball head. The second ball head is movably disposed in the second mounting cavity. The second mounting cavity is connected to the nozzle pipe through the connecting pipe. A second fixing sleeve for locking the second ball head is threadedly connected to the outer side of the second mounting cavity.

[0007] Preferably, the nozzle is threaded to the end of the support away from the second mounting cavity.

[0008] Preferably, the nozzle is a conical high-pressure nozzle or a flat wide-angle nozzle.

[0009] Preferably, the gas distribution row is provided with multiple connecting seats at intervals, and each connecting seat is respectively connected to a nozzle and a spray pipe assembly.

[0010] Preferably, the dust collection box includes a baffle, the edge of which is provided with a brush, and the mounting structure is a mounting hole opened on the baffle.

[0011] The beneficial effects of this invention are as follows: By setting a multi-angle adjustable nozzle assembly and cooperating with the first ball head to achieve multi-angle rotation of the nozzle, a multi-stage angle adjustment structure is formed. This structure allows the airflow to be further refined in direction through the nozzle assembly based on the nozzle angle adjustment, precisely targeting the fine areas of the cutting point (such as the contact edge between the tool and the workpiece, and dead corners where debris accumulates), effectively blowing up dust adhering to the tool surface and settling on the workpiece, ensuring that suspended dust can be efficiently extracted through the exhaust port on the dust collection hood, significantly improving the targeting and efficiency of dust collection.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See Figures 1 to 5As shown, the structure of this utility model is as follows: a spindle dust collection device includes a dust collection box 1 and a dust collection hood 2 connected to the dust collection box 1. The dust collection hood 2 is provided with an exhaust port 3. The dust collection box 1 is provided with an installation structure for adapting to the spindle. The dust collection box 1 is also provided with an air distribution 4. At least one connecting seat 5 is connected to the air distribution 4. One end of the connecting seat 5 is provided with a first mounting cavity 6 that communicates with the air distribution 4. A first ball head 7 is movably disposed in the first mounting cavity 6. A first fixing sleeve 8 for locking the first ball head 7 is threadedly connected to the outside of the first mounting cavity 6. A nozzle 9 that communicates with the first mounting cavity 6 is provided on the first ball head 7. A nozzle assembly 10 that can be adjusted at multiple angles is connected to the end of the nozzle 9 away from the first ball head 7. The nozzle assembly 10 is connected to the inside of the nozzle 9. Specifically, the dust collection box 1 adapts to the spindle through the installation structure and can move synchronously with the spindle to cover the cutting area, ensuring that the dust collection box 1 always covers the cutting area of ​​the tool, forming a local dust control space around the cutting point. After the dust collection hood 2 is connected to the dust collection box 1, its exhaust port 3 is connected to an external negative pressure device such as an industrial vacuum cleaner or a central dust collection system through a pipe, forming a continuous negative pressure field inside the dust collection box 1 to provide power for dust extraction. The air distribution vent 4, as an airflow distribution hub, can be connected to an external compressed air source such as an air compressor to evenly distribute high-pressure airflow to at least one connecting seat 5, ensuring stable air supply to each nozzle 9. The first mounting cavity 6 of the connecting seat 5 provides a space for the first ball head 7 to move. The first ball head 7 can rotate in any direction within the cavity, and the rotation angle range can be designed according to requirements, thereby driving the nozzle 9 to achieve multi-angle adjustment. When the tool is performing planar milling, deep groove cutting, or curved surface machining, the tilt direction of the nozzle 9 can be changed by rotating the first ball head 7, so that the airflow can be aligned with the cutting point from different directions. After adjusting to the target angle, tighten the first fixing sleeve 8 on the outside of the first mounting cavity 6 to fix the first ball head 7 through the thread locking force, so as to prevent the nozzle 9 angle from shifting due to vibration during the machining process and ensure the stability of the airflow direction. The nozzle 9 serves as an airflow transmission channel, guiding the compressed air from the air distributor 4 to the nozzle assembly 10 at its end. Its length can be designed according to the distance between the spindle and the cutting point, ensuring the airflow accurately targets the dust-generating area. The multi-angle adjustable nozzle assembly 10 connected to the end of the nozzle 9 further refines the airflow direction based on the nozzle 9's angle adjustment, allowing the airflow to target fine areas of the cutting point, such as the contact edge between the tool and the workpiece, and dead corners where debris accumulates. During operation, compressed air forms a high-speed airflow through the air distributor 4, connecting seat 5, nozzle 9, and nozzle assembly 10, blowing up the dust generated during cutting, including debris adhering to the tool surface and dust settled on the workpiece, suspending it in a suspended state. Simultaneously, the exhaust port 3 of the dust extraction hood 2 forms a directional suction airflow under negative pressure, rapidly drawing in the suspended dust and discharging it through pipes to an external collection device.

[0023] like Figure 4 , Figure 5As shown, the nozzle assembly 10 includes a support 11 and a connecting pipe 12. One end of the support 11 has a second mounting cavity 13, and the other end has a nozzle 14 communicating with the second mounting cavity 13. One end of the connecting pipe 12 is connected to the nozzle 9, and the other end has a second ball head 15. The second ball head 15 is movably disposed in the second mounting cavity 13. The second mounting cavity 13 is connected to the nozzle 9 through the connecting pipe 12. The outer side of the second mounting cavity 13 is threaded with a second fixing sleeve 16 for locking the second ball head 15. Specifically, the connecting pipe 12 connects the nozzle 9 and the support 11 to deliver airflow. The second ball head 15 can rotate within a small range in the second mounting cavity 13, driving the support 11 and the nozzle 14 to achieve fine angle adjustment. After adjustment, it is locked and fixed by the thread of the second fixing sleeve 16. This structure, together with the large-range adjustment of the first ball head 7, forms a two-stage angle control, enabling the nozzle 14 to accurately target the fine dust accumulation area of ​​the cutting point, such as the side of the tool or the groove of the workpiece, ensuring that the airflow efficiently disturbs the dust and guides it to the exhaust port 3.

[0024] Furthermore, the nozzle 14 is threadedly connected to the end of the support 11 away from the second mounting cavity 13. Specifically, the threaded connection design between the nozzle 14 and the support 11 allows the nozzle 14 to be quickly disassembled and replaced, making it convenient to flexibly select the appropriate nozzle 14 according to the characteristics of the cutting materials such as wood, metal and dust, light dust and heavy debris.

[0025] Furthermore, the nozzle 14 is either a conical high-pressure nozzle or a flat wide-angle nozzle. Specifically, the conical high-pressure nozzle can generate a concentrated high-speed airflow, which is suitable for blowing away stubborn dust such as metal shavings adhering to the surface of tools or workpieces; the flat wide-angle nozzle can form a large-area dispersed airflow, which is suitable for blowing away light, dispersed dust such as wood chips and plastic particles. The selective use of the two nozzles allows the device to adapt to different processing scenarios and ensures effective disturbance of various types of dust.

[0026] Furthermore, multiple connecting seats 5 are spaced apart on the air distribution duct 4, and each connecting seat 5 is respectively connected to a nozzle 9 and a nozzle assembly 10. Specifically, the multiple connecting seats 5 and the corresponding nozzles 9 and nozzle assemblies 10 on the air distribution duct 4 can form multiple directional airflows to the cutting area from different directions, covering a larger area of ​​dust generation, such as multiple cutting points of a multi-bladed tool, avoiding the blind spots of a single airflow. At the same time, the synergistic effect of multiple airflows can guide the dust more evenly to the exhaust port 3, improving the overall dust disturbance and collection efficiency.

[0027] like Figure 2As shown, the dust collection box 1 includes a baffle 17, and the edge of the baffle 17 is provided with a brush 18. The mounting structure is a mounting hole 19 opened on the baffle 17. Specifically, the baffle 17 of the dust collection box 1 is fitted with the spindle through the mounting hole 19 to ensure a stable fit between the device and the spindle. The brush 18 on the edge of the baffle 17 can flexibly fit the workpiece surface or the processing table to form a sealing barrier. At the same time, the flexibility of the brush 18 avoids scratching the workpiece and can maintain a continuous seal as the spindle moves to prevent dust from escaping from the edge.

[0028] In practical use, first, the dust collection box 1 is fitted onto the spindle using its own mounting structure, ensuring a stable fit between the spindle and the dust collection box 1. Then, the exhaust port 3 of the dust collection hood 2 is connected to an external negative pressure device through a pipe, and the air distributor 4 is connected to an external compressed air source, completing the basic connection. Subsequently, depending on the material of the workpiece to be processed, the type of tool, and the cutting method, the first fixing sleeve 8 is loosened, and the first ball head 7 is rotated to adjust the nozzle 9 to an approximate angle. After adjustment, the first fixing sleeve 8 is tightened to fix the angle. Then, the multi-angle adjustable nozzle assembly 10 at the end of the nozzle 9 is adjusted to further fine-tune the angle based on the nozzle 9 angle, ensuring that the airflow can accurately act on the expected dust generation area. During startup, the negative pressure device and compressed air source are turned on in advance. Under the action of negative pressure, the exhaust port 3 of the dust collection hood 2 forms a continuous negative pressure field inside the dust collection box 1. The air distributor 4 distributes the airflow to the connecting seat 5. The airflow sequentially passes through the first mounting cavity 6, the first ball head 7, and the nozzle 9 into the nozzle assembly 10 and is ejected as a high-speed airflow. When the spindle drives the tool to start cutting, the dust collection box 1 moves synchronously with the spindle, always covering the cutting area and forming a local dust control space around the cutting point. The dust generated by cutting is blown up by the directional airflow sprayed by the nozzle assembly 10 and forms a suspended state. At the same time, the negative pressure field of the dust suction hood 2 quickly sucks the suspended dust into the exhaust port 3 and discharges it to the external collection device through the pipe.

[0029] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
