Description

Technical Field

[0002] The machining center is a highly automated multifunctional CNC machine tool with a tool magazine and automatic tool changer. The graphite-specific composite machining center is a high-efficiency and high-stability machine tool equipment specially used for graphite processing based on the general-purpose machining center. It is energy-saving, environmentally friendly, and has excellent performance. This type of gantry composite machining center is most suitable for the processing of large and complex graphite products. The spindle head is modularly designed and can be equipped with a right-angle milling head, an extended milling head, and a universal milling head for processing surfaces of various specific angles. The workbench can be equipped with a fourth axis unit for the processing of rotating bodies. The graphite-specific gantry composite machining center uses fully enclosed internal and external protection and a centralized dust removal device. The dust recovery rate reaches more than 95%. Large-particle chips are transported to the chip collection box through a high-speed chip conveyor for centralized recovery. Dry cutting is used when processing graphite molds. A large amount of graphite dust is generated during the processing. The dust is easy to scatter and has strong conductivity. If the protection is not in place, it will cause great damage to the equipment and the environment.

[0003] When the graphite dust generated in the machining center is extracted and collected, because the graphite dust has a certain adsorption capacity, it is easy for part of the dust to be accumulated and adsorbed at the inlet of the extraction pipe during the long-term extraction process, resulting in dust blockage and affecting the dust extraction. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a modular composite machining center, which aims to solve the problem that when the graphite dust generated in the machining center is extracted and collected, because the graphite dust has a certain adsorption property, it is easy for a part of the dust to be accumulated and adsorbed at the inlet of the extraction pipe during the long-term extraction process, resulting in dust blockage and affecting the dust extraction.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0012] Furthermore, an air inlet is provided on the machining center, and a third filter is provided on the air inlet.

[0013] Furthermore, the machining center is provided with a sliding door to seal the machining center.

[0014] The beneficial effects of the present invention are:

[0015] A modular composite machining center of the present invention aims at the problem that the inlet of the extraction pipe is easily blocked due to the adsorption of graphite dust. The vibration motor arranged on the dust collecting cover can generate vibration regularly to loosen and fall off the graphite dust adsorbed at the inlet of the dust collecting cover, thereby avoiding blockage caused by the accumulation of a large amount of dust and effectively ensuring the continuous and stable operation of the dust extraction work.

[0016] The cleaning mechanism in the dust hood drives the brush to rotate through the driving motor, which can clean the second filter to prevent graphite dust from accumulating on the filter, ensuring smooth airflow in the dust hood and further improving the reliability and stability of the entire dust extraction system.

[0026] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0027] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figures 1 to 5 As shown, a modular composite machining center 1 comprises a machining center 1, an air inlet 18 is arranged on the machining center 1, a third filter screen 19 is arranged on the air inlet 18, and a sliding door 20 is arranged on the machining center 1 to make the machining center 1 airtight.

[0030] Machining center 1 plays a role in graphite machining with its highly automated characteristics and multifunctional design.

[0031] First of all, various types of tools are stored in its tool magazine. When receiving a processing instruction, the automatic tool changer will accurately select the appropriate tool according to the program requirements and install it on the spindle head.

[0032] The spindle head adopts modular design, which enhances the flexibility of processing. When it is necessary to process a profile with a specific angle, it can be equipped with a right-angle milling head, an extended milling head or a universal milling head.

[0033] The right-angle milling head enables the tool to perform cutting motion in a direction perpendicular to the spindle axis, thereby realizing the processing of specific vertical surfaces or right-angle edges of graphite workpieces;

[0034] Extending the milling head can extend the working range of the tool, making it easier to process some deeper parts or special locations;

[0035] The universal milling head can adjust the cutting direction of the tool within a range of multiple angles to meet the processing needs of complex surfaces, such as the processing of graphite products with curved surface transitions or multi-angle intersections.

[0036] The fourth axis unit mounted on the worktable plays a key role in the machining of rotating bodies.

[0037] When machining rotating graphite workpieces, the fourth axis unit can drive the workpiece to perform precise rotational motion around a specific axis.

[0038] During the machining process, the control system of the machining center 1 will accurately control the motion trajectory of the spindle head and the rotational motion of the fourth axis unit of the worktable according to the preset machining path and cutting parameters (such as spindle speed, feed speed, cutting depth, etc.).

[0039] When processing a cylindrical workpiece made of graphite, the spindle head drives the tool to perform rotational cutting, while the fourth axis unit causes the cylindrical workpiece to rotate at a constant speed around its central axis. Through the coordinated movement of the two, the tool can cut a shape and dimensional accuracy that meets the design requirements on the workpiece surface.

[0040] During the entire machining process, due to the use of dry cutting method, the graphite material is removed under the high-speed cutting action of the tool, forming a large amount of graphite dust and some large-particle chips.

[0041] A dust extraction mechanism 2 is provided on one side of the machining center 1, and the dust extraction mechanism 2 includes a dust box 3 fixedly arranged on the machining center 1, a first filter screen 4 is arranged in the dust box 3, and an exhaust fan 5 is installed at the bottom of the outer side surface of the dust box 3, and the air inlet end of the exhaust fan 5 is connected with the inside of the dust box 3 and the air inlet end of the exhaust fan 5 is located below the first filter screen 4.

[0042] A bellows 6 is connected to the dust box 3, a dust hood 7 is arranged on the side of the bellows 6 away from the dust box 3, a wire mesh 17 is fixedly connected to the dust hood 7 by bolts, a vibration motor 8 is fixedly installed on the dust hood 7, a plurality of shock-absorbing dampers 10 distributed in a circular array are arranged on the dust box 3, a baffle 11 is arranged on the side of the shock-absorbing damper 10 away from the dust box 3, the bellows 6 is fixedly connected to the baffle 11, a plurality of springs 12 distributed in a circular array are arranged between the baffle 11 and the dust hood 7, and a cover door 13 is hinged on the dust box 3.

[0043] A cleaning mechanism 9 is provided in the dust hood 7, and the cleaning mechanism 9 includes a second filter 14 fixedly installed in the dust hood 7, a drive motor 15 is installed on the second filter 14, and a brush 16 is fixedly connected to the output shaft of the drive motor 15, and the brush 16 is arranged in conflict with the second filter 14.

[0044] When the machining center 1 generates dust while machining graphite, the dust extraction mechanism 2 starts to work.

[0045] The exhaust fan 5 is started, which creates a negative pressure environment in the dust box 3 .

[0046] Since the dust box 3 is connected to the dust hood 7 through the bellows 6 , the air in the machining center 1 carries the graphite dust and flows toward the dust hood 7 under the action of the pressure difference.

[0047] The dust collecting hood 7 is located near the workbench of the machining center 1, and its shape and position can capture the flying graphite dust to the greatest extent.

[0048] The wire mesh 17 on the dust hood 7 plays a role in initially blocking larger foreign matter from entering the dust hood 7, thereby preventing the foreign matter from damaging or clogging the subsequent dust extraction components. When the dust-laden airflow passes through the dust hood 7, a portion of the dust will be directly blocked by the inner wall of the dust hood 7 and deposited, while most of the dust will continue to flow toward the dust box 3 along with the airflow.

[0049] Since graphite dust has adsorptive properties, it is easy to be adsorbed and accumulated at the inlet of the dust collecting hood 7 during long-term dust extraction, causing blockage.

[0050] To solve this problem, a vibration motor 8 is provided on the dust collecting cover 7. The vibration motor 8 starts to vibrate at a set time interval or according to the dust adsorption degree detection result.

[0051] When the vibration motor 8 is working, high-frequency vibration is generated, and this vibration is transmitted to the entire structure of the dust hood 7, so that the graphite dust adsorbed at the inlet of the dust hood 7 is separated from the inner wall surface under the action of vibration, re-enters the airflow, and flows toward the dust box 3 with the airflow.

[0052] At the same time, the cleaning mechanism 9 in the dust hood 7 is also working in coordination; the second filter 14 is installed in the dust hood 7, and its main function is to perform preliminary filtering on the airflow entering the dust hood 7 to prevent larger particles of dust from directly entering the bellows 6 and causing blockage.

[0053] The driving motor 15 installed on the second filter 14 drives the brush 16 to rotate, and the brush 16 is in close contact with the second filter 14. During the dust extraction process, the driving motor 15 is periodically started, and the brush 16 cleans the second filter 14, cleaning the graphite dust attached to the second filter 14, making it fall to the bottom of the dust hood 7, and then enter the dust box 3 driven by the airflow. Through the dual effects of the vibration motor 8 and the cleaning mechanism 9, the dust clogging at the inlet of the dust hood 7 and the second filter 14 inside is effectively prevented, ensuring the smooth flow of the dust extraction channel.

[0054] After the dust-laden airflow passes through the bellows 6 and enters the dust box 3, the first filter screen 4 can block the graphite dust particles. When the airflow passes through the first filter screen 4, the dust particles are blocked on the first filter screen 4, gradually accumulate to form a dust layer, and the dust remains in the dust box 3. As the processing continues, the dust on the first filter screen 4 will continue to increase. When the dust accumulates to a certain extent, it may affect the airflow and filtering effect. At this time, the dust in the dust box 3 can be cleaned by opening the hinged cover door 13 on the dust box 3, and the cleaned dust can be subsequently processed according to environmental protection requirements.

[0055] A plurality of shock-absorbing dampers 10 arranged in a circular array on the dust box 3, a baffle 11, and a plurality of springs 12 arranged in a circular array between the baffle 11 and the dust hood 7 together constitute a shock-absorbing and airflow stabilization system. The vibration motor 8 generates vibrations when working. If such vibrations are not controlled, they will be transmitted to the machining center 1, affecting the stability and machining accuracy of the equipment and generating additional noise. The shock-absorbing damper 10 can effectively absorb the vibration energy generated by the vibration motor 8, and convert the vibrations into other forms of energy such as heat energy through its own damping characteristics. The spring 12 plays a role of vibration and connection between the baffle 11 and the dust hood 7, and the graphite powder is separated from the dust hood 7. Through the shock-absorbing damper 10, the entire dust extraction mechanism 2 can operate in a stable and low-noise state, thereby improving the reliability and service life of the equipment.

[0056] The air inlet 18 provided on the machining center 1 and the third filter 19 on the air inlet 18 also play an important role in the stable operation of the entire dust extraction system. During the dust extraction process, the air in the dust box 3 is extracted by the exhaust fan 5, and new air needs to be replenished inside the machining center 1 to maintain the air pressure balance. The air inlet 18 is the channel for external air to enter the machining center 1. The third filter 19 can filter out dust, impurities, etc. in the air to prevent these foreign objects from entering the machining center 1 and causing adverse effects on the machining process, equipment components, etc.

[0057] After the external clean air enters the machining center 1 through the air inlet 18, it will participate in the dust carrying and circulation process, mix with the dust-containing air generated in the machining center 1, and then enter the dust extraction mechanism 2 again under the action of the exhaust fan 5 for dust separation and collection, thus forming a continuous airflow circulation process, ensuring that the dust in the machining center 1 can be continuously extracted and collected, keeping the machining environment relatively clean.

[0058] The machining process of the machining center 1 and the dust removal process of the dust extraction mechanism 2 are closely coordinated. When the machining center 1 starts to process graphite products, the cutting movement of the spindle head, the rotation movement of the fourth axis unit of the worktable and other machining actions are synchronized with the start of the exhaust fan 5 of the dust extraction mechanism 2. The graphite dust generated in the machining center 1 flows from the machining area to the dust hood 7 under the negative pressure generated by the dust extraction mechanism 2, and after the preliminary collection and anti-blocking treatment of the dust hood 7, it enters the dust box 3 for filtration and collection.

[0059] In this process, the operating parameters of the various moving parts of the machining center 1 (such as spindle speed, feed speed, etc.) will affect the amount of graphite dust generated and its flying characteristics, while the parameters such as the speed of the exhaust fan 5 of the dust extraction mechanism 2, the vibration frequency and amplitude of the vibration motor 8 of the dust collection hood 7, and the working cycle of the drive motor 15 of the cleaning mechanism 9 need to be reasonably adjusted according to the machining conditions of the machining center 1 to achieve the best dust collection effect and equipment operation stability.

[0060] When the machining center 1 performs high-speed cutting, the amount of graphite dust generated will increase and the flying speed will be faster. At this time, it is necessary to appropriately increase the rotation speed of the exhaust fan 5 to enhance the dust extraction capacity. At the same time, it may also be necessary to adjust the vibration frequency of the vibration motor 8 and the working cycle of the cleaning mechanism 9 accordingly to ensure that the dust hood 7 will not be blocked due to the increase in dust. The sliding door 20 on the machining center 1 plays a role in keeping the internal environment of the machining center 1 relatively closed during the whole process. When the sliding door 20 is closed, it can effectively prevent graphite dust from escaping to the external environment of the machining center 1, reducing the harm to the health of operators and the pollution to the surrounding environment.

[0061] The closed state of the sliding door 20 is also conducive to the dust extraction mechanism 2 forming a stable negative pressure environment inside the machining center 1, thereby improving the dust extraction efficiency.

[0062] During the processing, if the sliding door 20 needs to be opened for operations such as changing the tool or checking the workpiece, the dust extraction mechanism 2 is still working, but the large influx of external air will have a certain impact on the dust extraction effect. Therefore, when the sliding door 20 is opened, the speed of the exhaust fan 5 is appropriately adjusted or the dust extraction mechanism 2 is suspended, and the normal operating parameters are restored after the sliding door 20 is closed.

[0063] Through the close coordination between the various components of the machining center 1 and the dust extraction mechanism 2, the modular composite machining center 1 can effectively solve the collection and treatment problems of graphite dust while efficiently processing graphite products, achieve good machining performance, environmental protection performance and equipment operation stability, and meet the various needs of large and complex graphite product processing.

[0064] In actual use, various parameters of the machining center 1 and the dust extraction mechanism 2 can be further optimized and adjusted according to different graphite machining processes, characteristics of the machined workpieces, site environment and other factors to achieve the best working effect.

[0065] A modular composite machining center 1 of the present invention aims at the problem that the inlet of the extraction pipe is easily blocked due to the adsorption of graphite dust. The vibration motor 8 arranged on the dust collecting cover 7 can generate vibration regularly to loosen and fall off the graphite dust adsorbed at the inlet of the dust collecting cover 7, thereby avoiding blockage caused by the accumulation of a large amount of dust, and effectively ensuring the continuous and stable operation of the dust extraction work.

[0066] The cleaning mechanism 9 in the dust hood 7 drives the brush 16 to rotate through the driving motor 15, so as to clean the second filter 14 and prevent graphite dust from accumulating on the filter, thereby ensuring smooth airflow in the dust hood 7 and further improving the reliability and stability of the entire dust extraction system.

[0067] The structures such as the shock-absorbing damper 10, the baffle 11 and the spring 12 arranged on the dust box 3 can effectively reduce the vibration and noise generated when the exhaust fan 5 is working, extend the service life of the equipment, and also help to improve the stability and accuracy of the equipment operation.

[0068] The fully enclosed machining center 1 can effectively prevent the escape of graphite dust, reduce the harm to the health of operators and the adverse impact on the surrounding environment, and the centralized dust removal device can make the dust recovery rate reach more than %, and large-particle chips can also be centrally recovered by high-speed chip conveyors, which greatly optimizes the dust treatment link, improves the overall processing efficiency and quality, and reduces equipment maintenance costs and environmental risks.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
