Description

Technical Field

[0001] This invention relates to the field of laser processing and cutting equipment technology, and in particular to a high-efficiency cutting device for processing pilot valve components. Background Technology

[0002] In the industrial manufacturing field, pilot valve assemblies play a crucial role in the regulation and control of various fluid control systems, and therefore have extremely high requirements for their machining accuracy and quality. Among them, the cutting process, as an important part of the pilot valve assembly processing, directly affects the performance and reliability of the pilot valve.

[0003] Currently, there are many problems to be solved in the process of cutting pilot valves using lasers. The complex internal piping structure of the pilot valve is a major obstacle to the cutting process. Due to the existence of the piping structure, when using auxiliary airflow to assist cutting, the airflow can only act on the surface of the piping and cannot penetrate deep into the interior to provide comprehensive assistance to the entire cutting area. This is because the internal layout of the piping obstructs the airflow, preventing it from evenly covering the cutting area, which leads to the generation of cutting residue. This cutting residue not only damages the smoothness and finish of the pilot valve surface, but more seriously, it may affect the flow characteristics of the fluid inside the pilot valve, reduce its control accuracy and working efficiency, and even cause system failure.

[0004] Meanwhile, the escape of cutting gas during the cutting process is also a significant issue. Due to the influence of the pipeline structure, the cutting gas cannot be effectively concentrated in the cutting area. A large amount of escaped gas cannot fully exert its cooling effect on the cutting surface. As the temperature of the cutting surface becomes too high, defects such as thermal deformation and micro-cracks are prone to occur. This not only reduces the dimensional accuracy of the pilot valve but may also change the physical properties of the material, thereby affecting the overall quality and service life of the pilot valve assembly. Moreover, the molten material carried during the escape process will splash everywhere, not only polluting the working environment but also potentially adhering to the processing equipment and surrounding components. This not only requires additional time and effort for cleaning but may also interfere with other production processes, affecting the continuity and stability of the entire production process.

[0005] To address the aforementioned issues, existing solutions primarily focus on improving external cutting equipment and optimizing auxiliary airflow injection methods. However, these methods fail to adequately consider the crucial factor of the pilot valve's internal piping structure, thus failing to fundamentally resolve the airflow obstruction problem. While they improve cutting performance to some extent, they still struggle to effectively control issues such as cutting residue, cutting gas escape, and molten material recovery.

[0006] In summary, existing pilot valve assembly cutting processes suffer from numerous shortcomings when dealing with complex internal piping structures, such as cutting residue, gas escape during cutting, and difficulties in molten material recovery. These shortcomings severely restrict the processing quality and production efficiency of pilot valve assemblies. Therefore, it is necessary to develop an innovative cutting device that incorporates an airflow mechanism inside the pipe and combines it with a negative pressure design to effectively solve the problem of cutting residue, optimize the cutting effect, improve the processing level of pilot valve assemblies, and meet the high-quality and high-precision requirements of industrial production for pilot valves. Summary of the Invention

[0019] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention.

[0020] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this invention.

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0022] Reference manual attached Figures 1 to 7 The present invention provides a structure for a high-efficiency cutting device for processing pilot valve assemblies, comprising: a moving platform 6, which includes a moving table and a processing table; The mobile platform includes a fixed tube 4, a mounting plate 9, and a driving device; The processing table includes a cutting table, an air intake pump 11, an exhaust pump 12, a mounting plate 9, a second connecting piece 2, a recovery device, a reversing device, and a cutting device. The cutting table includes a processing platform 3, a sliding plate 301, an adjusting plate 302, a first sliding bar 15, a first connecting piece 1, a first drive motor 10, and a transmission gear 1001; The recycling device includes a recycling component 21, a second sliding bar 23, a fourth drive motor 24, a sealing sleeve 25, a guide tube 26, a limiting top component 22, and a ventilation slot 27; The reversing device includes an electric push rod 8, a lifting component 13, a triangular support component 16, a third drive motor 18, and a second drive motor 17. The cutting device includes a laser cutter 19 and a high-speed blower 1901.

[0023] It should be noted that a high-efficiency cutting device for processing pilot valve components, by setting a structure with a recovery component 21, can effectively form a corresponding air duct at the welding position according to the welding state during the welding process. This allows the welding gas to effectively cover the welding end face, while effectively reducing the escape of welding gas, so as to effectively recover the molten material during the welding process.

[0024] Furthermore, the driving device includes a second sliding bar 23, a processing platform 3, a first connecting member 1, and a fourth driving motor 24. The second sliding bar 23 is fixedly installed on the rear side of the fixed tube 4. The processing platform 3 is slidably arranged on the upper end of the fixed tube 4. The fourth driving motor 24 is fixedly installed on the middle side of the processing platform 3. The output end of the fourth driving motor 24 is engaged with the second sliding bar 23. The processing platform 3 is connected to the fixed tube 4 through the first connecting member 1. The lower end of the processing platform 3 is provided with a groove corresponding to the second guide member 7.

[0025] It should be noted that when the fourth drive motor 24 is started, the sealing sleeve 25 and the second sliding strip 23 engage, thereby driving the entire processing platform 3 to move horizontally. At the same time, when the processing platform 3 moves horizontally, it is connected to the fixed pipe 4 through the second connector 2. The fixed pipe 4 can effectively limit the displacement and rotation of the structure, thereby ensuring the stability and safety of the structure.

[0026] In one possible implementation, a first sliding bar 15 is fixedly installed at the upper middle part of the processing platform 3, a first drive motor 10 is fixedly installed at the upper middle part of the processing platform 3, a transmission gear 1001 is fixedly installed at the lower output end of the first drive motor 10, the transmission gear 1001 is meshed with the sliding plate 301, a first connecting member 1 is provided on the side of the sliding plate 301, the upper end of the first connecting member 1 is fixedly connected to the sliding plate 301, the lower end of the first connecting member 1 is fixedly connected to the processing platform 3, a first guide member 5 is provided at the upper end of the processing platform 3, and a sliding groove corresponding to the first guide member 5 is opened at the lower end of the sliding plate 301.

[0027] It should be noted that the first drive motor 10 can drive the transmission gear 1001 to rotate. The transmission gear 1001 can drive the sliding plate 301 to move back and forth within the range of the first sliding bar 15. The upper end of the processing platform 3 is provided with a first guide 5 and the lower end of the sliding plate 301 is provided with a sliding groove for matching. At the same time, it can be connected to the processing platform 3 with the first connecting piece 1 on the side of the sliding plate 301, which can effectively maintain the stability of the movement of the sliding plate 301.

[0028] In one possible implementation, a guide cylinder 14 is fixedly installed on the front center of the mounting plate 9, a return air plate 20 is fixedly installed on the front side of the guide cylinder 14, an annular component 2001 is provided inside the return air plate 20, a recovery component 21 is fixedly installed at the front end of the guide cylinder 14, a plurality of fourth drive motors 24 are equidistantly and alternately arranged on the side of the recovery component 21, a guide tube 26 is fixedly installed on the outside of the recovery component 21 at the position of the fourth drive motor 24, a ventilation groove 27 is opened on the side of the guide tube 26, and staggered square through grooves are opened on both sides of the fourth drive motor 24 at the position of the ventilation groove 27. A second sliding strip 23 is fixedly installed between the fourth drive motor 24 and the recovery component 21.

[0029] It should be noted that when the recovery component 21 is inserted into the pilot valve assembly to be inserted, the fourth drive motor 24 is subjected to pipeline pressure, which compresses the second sliding bar 23. The fourth drive motor 24 moves towards the guide tube 26. At this time, the ventilation slot 27 and the square through slot opened on the side of the fourth drive motor 24 coincide. The space inside the pilot valve assembly is connected to the cavity structure inside the recovery component 21. However, since the pipeline opening of the pilot valve assembly is not cut open at this time, when the first connecting component 1 starts cutting, the annular component 2001 can absorb the auxiliary gas and cutting debris sprayed by the high-speed blower 1901. After the pilot valve assembly is cut with a notch, since the surface cut of the pilot valve assembly is connected to the space of the fourth drive motor 24, a negative pressure is generated at the ventilation slot 27. This allows the auxiliary gas and debris at the cut position to pass through the ventilation slot 27, forming a corresponding and stable air duct at the cut position. Without affecting the cutting, the auxiliary gas can cover the cut surface and reduce welding defects.

[0030] In one possible implementation, a sealing sleeve 25 is provided between the guide tube 26 and the fourth drive motor 24, and the sealing sleeve 25 is a component made of elastic rubber.

[0031] It should be noted that the sealing sleeve 25 can ensure the airtightness between the fourth drive motor 24 and the guide tube 26. At the same time, the sealing sleeve 25, which is made of elastic rubber, can be stretched and extended without affecting the movement between the guide tube 26 and the fourth drive motor 24.

[0032] In one possible implementation, the recycling component 21 has a cylindrical cavity structure in the middle, the guide cylinder 14 has a PVC pipe in the middle, the PVC pipe in the middle of the guide cylinder 14 is fixedly connected to the air inlet of the exhaust gas pump 12, and the lower end of the annular component 2001 is connected to the PVC pipe inside the guide cylinder 14.

[0033] It should be noted that the exhaust gas pump 12 can draw air from the guide cylinder 14. The negative pressure generated by the exhaust gas pump 12 can quickly remove the gas and impurities in the production process, thereby forming a stable air duct between the ejected gas channel and the welding surface, which can improve the stability of welding quality.

[0034] In one possible implementation, an electric push rod 8 is fixedly mounted on the upper end of the mounting plate 9, a lifting member 13 is provided at the lower output end of the electric push rod 8, a triangular support member 16 is fixedly mounted on the front side of the lifting member 13, a third drive motor 18 is fixedly mounted on the front side of the triangular support member 16, a second drive motor 17 is fixedly mounted at the lower end of the third drive motor 18, and a laser cutter 19 is fixedly mounted at the output end of the second drive motor 17.

[0035] It should be noted that the electric push rod 8 can control the overall up and down movement of the triangular support 16, the third drive motor 18 can control the rotation of the second drive motor 17 in the horizontal direction, and the second drive motor 17 can control the rotation of the laser cutting machine 19 in the vertical direction.

[0036] In one possible implementation, the upper end of the mounting plate 9 is provided with a square groove, the lifting member 13 is vertically arranged inside the square groove, a threaded rod is fixedly installed on the lower side of the electric push rod 8, and a threaded groove corresponding to the threaded rod is provided in the middle of the lifting member 13.

[0037] It should be noted that when the electric push rod 8 drives the lower threaded rod to rotate, it can drive the lifting component 13 to move up and down.

[0038] In one possible implementation, a cutting device is fixedly installed on the front side of the second drive motor 17 in the phase-changing device, and a laser cutting machine 19 is fixedly installed on the front output end of the second drive motor 17. A high-speed blower 1901 is fixedly installed on the lower end of the laser cutting machine 19, and the high-speed blower 1901 is a ring device arranged at the lower end of the laser cutting machine 19.

[0039] It should be noted that the high-speed blower 1901 can provide full coverage of the welding end, allowing the auxiliary gas to cover the area around the welding point.

[0040] In one possible implementation, an air intake pump 11 is fixedly installed on the side of the mounting plate 9, and an exhaust pump 12 is fixedly installed on the side of the mounting plate 9 below the air intake pump 11. The air intake pump 11 is connected to a high-speed blower 1901 via a hose.

[0041] It should be noted that the air pump 11 can pump welding gas into the high-speed blower 1901, thereby improving the yield of the welding machine. In summary, by providing a structure with a recovery component 21, during the welding process, a corresponding air duct can be effectively formed at the welding position according to the welding state, which can effectively cover the welding end face with welding gas and effectively reduce the escape of welding gas, so as to effectively recover the molten material during the welding process.

[0042] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this embodiment of the invention, by providing a recovery component 21, when the recovery component 21 is inserted into the pilot valve assembly to be inserted, the fourth drive motor 24 is subjected to pipeline pressure, which compresses the second sliding bar 23. The fourth drive motor 24 moves towards the guide tube 26. At this time, the ventilation groove 27 and the square through groove opened on the side of the fourth drive motor 24 coincide. The space inside the pilot valve assembly is connected to the cavity structure inside the recovery component 21. However, since the pipeline opening of the pilot valve assembly is not cut open at this time, when the first connecting component 1 starts cutting, the annular component 2001 can absorb the auxiliary gas and cutting debris sprayed by the high-speed blower 1901. After the pilot valve assembly is cut with a notch, since the surface cut of the pilot valve assembly is spatially connected to the fourth drive motor 24, a negative pressure is generated at the ventilation groove 27. This allows the auxiliary gas and debris at the cut position to pass through the ventilation groove 27, forming a corresponding and stable air duct at the cut position. Without affecting the cutting, the auxiliary gas can cover the cut surface and reduce welding defects.
