Description

Technical Field

[0001] The present application relates to the field of metal sheet processing equipment, and in particular to a gantry milling machine for metal sheet processing. Background Art

[0002] In the sheet metal processing industry, widely used machine tools include CNC lathes, drilling machines, grinders, etc. Among them, gantry milling machines are widely used in the processing of large sheet metal because of their high precision and stability. This high precision and stability make the gantry milling machine one of the indispensable and important equipment in modern manufacturing. With the continuous advancement of industrialization, higher requirements are put forward for the quality and efficiency of sheet metal processing. The application scope of gantry milling machines is also expanding, covering many fields such as automobile manufacturing, aerospace, and mold manufacturing.

[0003] In the actual production process, in order to ensure the processing quality and extend the tool life, coolant is usually sprayed during the processing. After long-term use, the coolant will carry a large amount of cutting debris, which is easy to adhere to the card slot of the workbench. At present, the chip cleaning methods of the gantry milling machine workbench mainly include manual cleaning method, high-pressure water gun flushing method and air gun blowing method. The manual cleaning method is mainly for workers to manually remove the debris in the card slot with a scraper or brush after each processing is completed; the high-pressure water gun flushing method is to use a high-pressure water gun to flush the card slot, which can effectively remove most of the debris; the air gun blowing method uses compressed air to blow the card slot, which can quickly remove some loose debris.

[0004] Although the above methods can solve the problem of debris accumulation in the card slot to a certain extent, they each have obvious shortcomings. The manual cleaning method is not only time-consuming and labor-intensive, but the cleaning effect is greatly affected by human factors, making it difficult to achieve the purpose of thorough cleaning; although the high-pressure water gun flushing method can effectively remove a large amount of debris, there is a serious problem of water resource waste, and the high-pressure water flow may damage the workbench surface and increase maintenance costs; although the air gun purging method is fast, it has limited effect on already stuck debris and still requires manual assistance for cleaning. Therefore, the existing debris cleaning methods generally have the problems of incomplete cleaning, long time consumption, and high labor intensity. Summary of the invention

[0005] In order to improve the debris cleaning effect and cleaning efficiency of the workbench and reduce the labor intensity of workers, the present application provides a gantry milling machine for metal sheet processing.

[0006] The present application provides a gantry milling machine for metal sheet processing, which adopts the following technical solution: A gantry milling machine for processing metal plates comprises a workbench, wherein the surface of the workbench is provided with a plurality of parallel slots, and the slots are opened at both ends; cleaning components are slidably connected in the plurality of slots, and the workbench is provided with a driving mechanism for driving the plurality of cleaning components to move synchronously along the extending direction of the slots, an internal wiping piece is provided in front of the cleaning component, the internal wiping piece is located in the slots and abuts against the inner walls of the slots, and an air jet mechanism is provided behind the cleaning component, when the driving mechanism drives the plurality of cleaning components to move forward, the internal wiping piece in front of the cleaning component scrapes off the debris in the slots, and the air jet mechanism behind the cleaning component sprays the inner walls of the slots to remove the debris remaining on the inner walls of the slots.

[0007] By adopting the above technical solution, the cleaning member moves synchronously along the extension direction of the card slot under the drive mechanism, so that the internal wiper can efficiently scrape the debris in the card slot, and the jet mechanism can spray the inner wall of the card slot behind the cleaning member to further remove the fine debris remaining on the inner wall of the card slot. This design not only improves the cleaning effect and cleaning efficiency of the card slot, but also reduces the labor intensity of workers.

[0008] Preferably, the tops of several of the cleaning components protrude vertically out of the slots, and the driving mechanism includes a connecting member connected to the tops of the several cleaning components, two sliding seats respectively slidably connected to both sides of the workbench, and a transmission assembly for driving the two sliding seats to move synchronously, and the two ends of the connecting member are respectively connected to the sliding seats on both sides of the workbench.

[0009] By adopting the above technical solution, the top of the cleaning component protrudes vertically out of the slot, and the driving mechanism includes a connecting component connected to the top of a number of cleaning components, two sliding seats respectively slidably connected to the two sides of the workbench, and a transmission assembly for driving the two sliding seats to move synchronously. When the transmission assembly drives the two sliding seats to move synchronously, the connecting component drives all the cleaning components to move synchronously along the extension direction of the slot. In this way, it can not only ensure that each cleaning component acts on the inner wall of the slot at the same time, thereby improving the cleaning efficiency and uniformity, but also avoid the problem of incomplete cleaning caused by the single action of a single cleaning component. In addition, due to the protruding design of the top of the cleaning component, it is convenient to effectively connect with the connecting component, making the entire drive system more stable and reliable.

[0010] Preferably, the jet mechanism includes an air pump arranged at a sliding seat, an air supply pipe connected to the output end of the air pump, a plurality of branch pipes connected to the air supply pipe, and a nozzle assembly connected to the air outlets of the branch pipes, the plurality of branch pipes corresponding one-to-one to a plurality of slots, and the nozzle assembly at the air outlet of the branch pipe extends into the corresponding slot and is used to spray the inner wall of the slot.

[0011] By adopting the above technical solution, the air pump installed at the sliding seat can generate stable gas pressure, and the air supply pipe transports the gas to each branch pipe, and then the nozzle assembly on the branch pipe accurately sprays it onto the inner wall of the corresponding card slot. This design can not only efficiently remove the residual debris in the card slot, but also avoid manual intervention during the cleaning process, thereby improving the cleaning efficiency and quality. At the same time, since the nozzle assembly extends into the interior of the card slot, it can deeply clean every corner of the card slot to ensure thorough cleaning.

[0012] Preferably, several of the cleaning components are vertical tube bodies, and the connecting components are horizontal tube bodies, and the internal pipelines of several of the cleaning components are connected to the internal pipelines of the connecting components. The cleaning component is located at one end inside the card slot and is open toward the nozzle assembly, and the internal pipeline of the connecting component is connected to the air inlet end of the air pump. A filter assembly is provided at the connection between the internal pipeline of the connecting component and the air pump. When the jet mechanism is working, the air pump supplies air to the air supply pipe, and the airflow is sprayed out through the branch pipe and the nozzle assembly to clean the debris adhered to the inner wall of the card slot, and the air pump sucks air into the inside of the card slot through the internal pipeline of the cleaning component to collect the debris, and the filter assembly filters and collects the debris flowing through the internal pipeline of the connecting component.

[0013] By adopting the above technical solution, when the driving mechanism drives the cleaning component to move forward, the internal wiper first physically scrapes the debris in the slot, and then the jet mechanism sprays gas to the inner wall of the slot to ensure that the remaining fine debris is also cleaned up, thereby improving the cleaning effect and efficiency; in addition, the air pump not only delivers high-pressure gas to the nozzle assembly through the air supply pipe and the branch pipe to remove the stubborn debris on the inner wall of the slot, but also can suction the inside of the slot through the internal pipeline of the cleaning component, suck in the loosened debris and collect it through the filter assembly, avoiding secondary pollution and further improving the cleaning effect. Since most of the debris is scraped and cleaned by the internal wiper, the filtering pressure of the filter assembly can be greatly reduced, and the filter assembly does not need to be frequently shut down to clean, which is beneficial to improving the cleaning efficiency.

[0014] Preferably, the cleaning member is provided with a blocking plate, one end of which extends toward the rear of the cleaning member and is used to block the upper opening of the card slot at the rear position of the cleaning member.

[0015] By adopting the above technical solution, the sealing plate forms a relatively closed cleaning environment with the slot behind the cleaning component, which can effectively prevent the debris generated by the jet mechanism during the cleaning process from splashing into other uncleaned areas on the workbench or the surrounding environment, thereby keeping the working environment clean. The relatively closed cleaning environment provides favorable conditions for the air pump to suction air, which is beneficial to improving the collection efficiency of residual debris.

[0016] Preferably, one end of the blocking plate extends toward the front of the cleaning member and is used to block the upper opening of the card slot in front of the cleaning member.

[0017] By adopting the above technical solution, the blocking plate forms the slot in front of the cleaning component into a relatively closed cleaning space, which can effectively prevent the debris accumulated on the internal wiping piece during the cleaning process from overflowing onto the workbench surface, which is conducive to the cleanliness of the workbench surface.

[0018] Preferably, an external wiping piece is provided between adjacent sealing plates, and the external wiping piece is closely attached to the surface of the workbench. When the driving mechanism drives the cleaning component to move, the sealing plate drives the external wiping piece to move, and the external wiping piece cleans the debris on the surface of the workbench.

[0019] By adopting the above technical solution, the sealing plate drives the external wiping member to stick close to the surface of the workbench during the movement. As the driving mechanism drives the cleaning component to move, the external wiping member can continuously wipe the surface of the workbench, effectively removing the cutting debris remaining on the workbench, improving the cleaning efficiency and cleanliness, reducing the workload of manual cleaning, and improving the overall work efficiency.

[0020] Preferably, a mounting groove communicating with the internal pipeline is provided on the outer side of the connecting component, and the filter assembly is a filter screen, and the filter screen is inserted into the mounting groove.

[0021] By adopting the above technical solution, a mounting groove connected to the internal pipeline is opened on the outside of the connecting component, and the filter assembly is a filter screen, which is plugged into the mounting groove. This method makes the filter screen easy to replace and clean, ensuring that a good filtering effect can be maintained during long-term use, and avoiding the impact of airflow flow and cleaning efficiency due to filter screen blockage. At the same time, the plug-in installation structure simplifies the assembly process, reduces maintenance costs, and improves the reliability and service life of the equipment.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The internal wiping member and the jet mechanism of the cleaning component work together to efficiently remove the debris in the card slot, especially the debris stuck on the inner wall of the card slot, which improves the cleaning efficiency and cleanliness; 2. The jet mechanism can not only remove the debris remaining on the inner wall of the card slot, but also collect the debris into the filter component through the suction function, preventing the debris from entering the card slot again or scattering on the workbench, reducing the risk of secondary contamination; 3. The design of the blocking plate effectively closes the upper openings of the front and rear card slots of the cleaning component, while providing a good cleaning area and cleaning conditions for the jet mechanism and the internal wiper, which is beneficial to the cleaning effect.

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The present application embodiment discloses a gantry milling machine for processing metal plates, referring to Figure 1 , including a workbench 1, which can reciprocate longitudinally along the fixed bed rail, the milling head slide of the gantry milling machine can reciprocate transversely along the beam rail, and the milling head slide can reciprocate vertically along the slide rail. Both adopt the AC servo motor drive ball screw drive method. The surface of the workbench 1 is provided with a plurality of parallel slots 11, which extend longitudinally and are distributed transversely, and the slots 11 are opened at both ends. The slots 11 are used to install the fixture.

[0031] Reference Figure 2 and Figure 3In this embodiment, a plurality of the card slots 11 are all slidably connected with cleaning members 2, a driving mechanism 3 is installed on the workbench 1 for driving the plurality of cleaning members 2 to synchronously move along the extending direction of the card slots 11, an internal wiping member 21 is arranged in front of the cleaning member 2, the internal wiping member 21 is located in the card slot 11 and abuts against the inner wall of the card slot 11, and an air jet mechanism 4 is arranged behind the cleaning member 2. When the driving mechanism 3 drives the plurality of cleaning members 2 to move forward, the internal wiping member 21 in front of the cleaning member 2 scrapes the debris in the card slot 11, and the air jet mechanism 4 behind the cleaning member 2 sprays the inner wall of the card slot 11 to remove the debris remaining on the inner wall of the card slot 11, thereby significantly improving the effect and efficiency of debris cleaning and reducing the labor intensity of workers.

[0032] Specifically, the cleaning member 2 is a vertical tube body, and the vertical tube body can be made of stainless steel, which has good corrosion resistance and wear resistance, or aluminum alloy material can be used to reduce weight while maintaining sufficient rigidity. In the present embodiment, the internal wiping member 21 is made of cotton strips or sponge strips, which are fixed to the front end of the cleaning member 2 and are in close contact with the inner wall of the slot 11, and the debris in the slot 11 is scraped off by friction. The cotton strips are suitable for smaller debris, and the sponge strips are suitable for larger particles of debris. Both can be disassembled and replaced, which is convenient for cleaning and maintenance. In addition, nylon bristles can also be used as the internal wiping member 21, which is suitable for stubborn adhesion.

[0033] Reference Figure 2 and Figure 4 In this embodiment, the driving mechanism 3 includes a connecting member 33, a sliding seat 31 and a transmission assembly 32. The connecting member 33 is a horizontal tube body, and the connecting member 33 spans above the workbench 1. The cleaning member 2 protrudes upward from the top of the slot 11 and is fixedly connected to the connecting member 33. Both ends of the connecting member 33 extend out of the workbench 1 and bend downward, and are respectively fixedly connected to the sliding seats 31 on both sides of the workbench 1. The sliding seat 31 can slide smoothly on the guide rails on both sides of the workbench 1, and the two sliding seats 31 are controlled by the transmission assembly 32 to move synchronously. The transmission assembly 32 can adopt an electric screw drive, and the screw is driven to rotate by a stepping motor to achieve precise positioning of the sliding seat 31.

[0034] Reference Figure 2 and Figure 5In this embodiment, the jet mechanism 4 includes an air pump 41, an air supply pipe 42, a branch pipe 43 and a nozzle assembly 44. The air pump 41 can be a small and efficient centrifugal air pump 41 to provide stable gas pressure and ensure the jet effect. There are two air pumps 41, which are respectively installed on two sliding seats 31. The air supply pipe 42 can be made of flexible plastic pipes, which are easy to bend and adjust the position, or a metal steel pipe can be used to improve the stability of the jet mechanism 4. The number of branch pipes 43 is the same as that of the card slots 11. A nozzle assembly 44 is connected to the end of each branch pipe 43. The nozzle assembly 44 extends into the card slot 11, accurately aligns with the inner wall of the card slot 11, and sprays high-speed airflow to effectively remove residual debris. The nozzle assembly 44 can be made of copper material, which has good thermal conductivity and high temperature resistance to avoid damage due to long-term use.

[0035] In the embodiment, the two ends of the internal pipeline of the connecting member 33 are respectively connected to the air inlet ends of the air pump 41 on both sides of the workbench 1, and a filter assembly 34 is installed at the bending section of the connecting member 33. When the jet mechanism 4 is working, the air pump 41 supplies air to the air supply pipe 42, and the airflow is ejected through the branch pipe 43 and the nozzle assembly 44 to clean the debris adhered to the inner wall of the card slot 11. At the same time, the air pump 41 sucks air into the inside of the card slot 11 through the connecting member 33 and the internal pipeline of the cleaning member 2 to collect the fallen debris. The filter assembly 34 filters and collects the debris flowing through the internal pipeline of the connecting member 33 to prevent the pipeline from being blocked. The filter assembly 34 can use a multi-layer filter screen to intercept impurities of different particle sizes layer by layer to ensure the cleanliness of the airflow. In this embodiment, a mounting groove connected to the internal pipeline is opened on the outside of the connecting member 33, and the filter screen is plugged into the mounting groove to facilitate the removal and cleaning of the filter screen.

[0036] In this embodiment, a blocking plate 22 is fixed to the periphery of the cleaning member 2, one end of the blocking plate 22 extends to the rear of the cleaning member 2 and is used to block the upper opening of the slot 11 at the rear position of the cleaning member 2, and the other end of the blocking plate 22 extends to the front of the cleaning member 2 and is used to block the upper opening of the slot 11 at the front position of the cleaning member 2. The blocking plate 22 can be made of rubber or silicone material, has a certain elasticity, and can fit tightly to the upper opening edge of the slot 11 to enhance the sealing effect. Another option is polyurethane material, which has better wear resistance and tear resistance. The blocking plate 22 forms a relatively closed cleaning environment for the slot 11 behind the cleaning member 2, which can effectively prevent the debris generated by the jet mechanism 4 during the cleaning process from splashing into other uncleaned areas or the surrounding environment on the workbench 1, keeping the working environment clean, and the relatively closed cleaning environment provides favorable conditions for the air pump 41 to inhale, which is conducive to improving the collection efficiency of residual debris. The blocking plate 22 forms the slot 11 in front of the cleaning member 2 into a relatively closed cleaning space, which can effectively prevent the debris accumulated by the internal wiper 21 during the cleaning process from overflowing onto the surface of the workbench 1, thereby facilitating the cleanliness of the surface of the workbench 1.

[0037] In this embodiment, the sealing plate 22 behind the cleaning component 2 is bent downward into the slot 11 and slidably cooperates with the slot 11. The nozzle assembly 44 of the jet mechanism 4 is embedded in the sealing plate 22 inside the slot 11. Through the connection of the sealing plate 22, it is beneficial to achieve the purpose of synchronous movement of the cleaning component 2 and the nozzle assembly 44.

[0038] In this embodiment, an external wiping piece 23 is arranged between adjacent sealing plates 22. The external wiping piece 23 is made of sponge. The external wiping piece 23 is closely attached to the surface of the workbench 1. When the driving mechanism 3 drives the cleaning component 2 to move, the sealing plate 22 drives the external wiping piece 23 to move, and the external wiping piece 23 cleans the debris on the surface of the workbench 1.

[0039] A heating element is provided inside the other cleaning components 2, and the cooling liquid adhering to the inner wall of the card slot 11 is evaporated quickly by local heating, thereby loosening the debris and improving the cleaning efficiency. The heating element can be a heating wire, evenly distributed inside the cleaning component 2, and the heating temperature is controlled by a temperature control switch to avoid overheating and damage to the components. Another option is a PTC heating sheet, which has the advantages of constant temperature and energy saving, and can maintain a stable heat output even if used for a long time.

[0040] The implementation principle of this embodiment is: The transmission assembly 32 drives the sliding seat 31 to slide smoothly on the guide rails on both sides of the workbench 1, and the sliding seat 31 drives all the cleaning members 2 to move forward synchronously along the extension direction of the card slot 11 through the connecting member 33. In this process, the internal wiping member 21 in front of the cleaning member 2 is in close contact with the inner wall of the card slot 11, and the debris in the card slot 11 is scraped off by friction. At the same time, the jet mechanism 4 behind the cleaning member 2 is started, and the air pump 41 sprays high-speed airflow to the inner wall of the card slot 11 through the air supply pipe 42 and the branch pipe 43, further removing the debris remaining on the inner wall of the card slot 11. In addition, the internal pipeline of the connecting member 33 is also connected to the air inlet end of the air pump 41, and a filter assembly 34 is arranged in the middle. When the air pump 41 is working, it can not only spray air to the outside, but also suck air into the inside of the card slot 11 through the internal pipeline of the cleaning member 2, effectively collecting and discharging debris, thereby significantly improving the effect and efficiency of debris cleaning, especially in large-scale production, greatly reducing the cost and time of manual cleaning.

[0041] In other embodiments, the drive mechanism 3 can be installed at other positions of the gantry milling machine instead of being directly connected to the worktable 1, so that the drive mechanism 3, the cleaning component 2 and the jet mechanism 4 constitute a chip cleaning system that is completely independent of the worktable 1, so as to reduce the impact of the chip cleaning system on the worktable 1 when processing the workpiece. When performing the cleaning work inside the working slot 11, it is necessary to ensure the position accuracy of the cleaning component 2 so that the cleaning component 2 and the jet mechanism 4 can smoothly enter the slot 11 and complete the chip cleaning work.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
