Description

Technical Field

[0001] The present application relates to the technical field of hydrogen storage bottle mouth processing equipment, and in particular to a special machine for processing the mouth of a hydrogen storage bottle that is used for both Type III and Type IV bottles. Background Art

[0002] In the current hydrogen storage cylinder manufacturing sector, Type III hydrogen storage cylinders (aluminum alloy liner) and Type IV hydrogen storage cylinders (plastic liner) are widely used in fuel cell vehicles, hydrogen energy storage and transportation, and other fields. The two types of cylinders have different structures and material properties, and therefore have different process requirements for bottle mouth processing. Type III hydrogen storage cylinders have excellent strength and corrosion resistance because their liner is made of aluminum alloy. Their bottle mouths are usually machined, requiring precision thread cutting on high-strength metal materials. This requires high precision and cutting force from the machining equipment. Type IV hydrogen storage cylinders, on the other hand, have plastic liner, a lighter overall bottle body, and require a more special bottle mouth processing method. Plastic materials are highly heat-sensitive during processing and are easily deformed by temperature, so higher control requirements are placed on the processing temperature and cutting force.

[0003] To meet the processing requirements for different types of hydrogen storage cylinder necks, the main technical solutions include: First, designing separate specialized equipment for Type III and Type IV cylinders. While this approach effectively meets the processing requirements of each, it also introduces issues such as a wide variety of equipment types and complex maintenance. Second, using general-purpose equipment for processing requires frequent tool changes and parameter adjustments, resulting in low production efficiency and inconsistent processing quality. Summary of the Invention

[0004] In order to be able to process the bottle mouths of type III bottles and type IV bottles at the same time, the present application provides a special machine for processing the bottle mouths of type III bottles and type IV bottles.

[0005] The present application provides a special machine for processing bottle necks for both Type III and Type IV bottles, which adopts the following technical solutions:

The fixed vise and the movable vise are used to clamp and position the bottle mouth of the Type III bottle. The Type IV bottle clamp system includes an indexing vise and a positioning end head. The indexing vise is slidably connected to the main slide, and the indexing vise is located between the fixed vise and the movable vise. The positioning end head is fixedly connected to the movable vise and is located on the side of the movable vise away from the fixed vise. The indexing vise is used to clamp and position the bottle body of the Type IV bottle, and the positioning end head is used to abut and position one end of the Type IV bottle away from the spindle box.

[0007] By adopting this technical solution, the moving mechanism drives the spindle box to reciprocate in three dimensions: a first direction, a second direction perpendicular to the first direction, and the vertical direction, ensuring machining precision and flexibility. The main slide is arranged along the first direction to facilitate the transportation and positioning of hydrogen storage cylinders. The Type III and Type IV bottle clamp systems are compatible with both Type III and Type IV hydrogen storage cylinders, eliminating the need to purchase two sets of equipment, significantly reducing equipment investment costs.

[0008] Optionally, a mobile table drive mechanism and an indexing table drive mechanism are further provided on the hydrogen storage bottle fixing table, and the bodies of the mobile table drive mechanism and the indexing table drive mechanism are fixedly connected to the hydrogen storage bottle fixing table, and the output end of the mobile table drive mechanism is connected to the mobile table vise to drive the mobile table vise to reciprocate along the first direction, and the output end of the indexing table drive mechanism is connected to the indexing table vise to drive the indexing table vise to reciprocate along the first direction.

[0009] By adopting the above technical solution, the setting of the movable table drive mechanism and the indexing table drive mechanism enables the equipment to automatically control the rapid adjustment and movement of the fixture, while achieving precise control of the moving distance, ensuring the accurate positioning and stable clamping of Type III and Type IV bottles during the processing process, and improving the processing accuracy and quality.

[0010] Optionally, a control system is further included, and the control system is signal-connected with the spindle system, the type III bottle clamp system, the type IV bottle clamp system, the moving table drive mechanism and the indexing table drive mechanism.

[0011] By adopting the above-mentioned technical solution and introducing a control system, the dedicated machine can achieve precise control of the headstock, movable table drive mechanism, and indexing table drive mechanism, improving the equipment's level of automation. This not only reduces the need for manual intervention but also significantly improves processing stability and consistency. The control system can automatically adjust the position and motion trajectory of the headstock according to different processing requirements, ensuring precise positioning and processing accuracy for Type III and Type IV bottles during processing. At the same time, through linkage with the movable table drive mechanism and indexing table drive mechanism, it can quickly adapt to and optimize the processing of bottles of different materials.

[0012] Optionally, the fixed bench vise includes a fixed base, a fixed rail, two fixed table bottle mouth clamps and a fixed table bottle clamp driving mechanism, the fixed rail is fixedly connected to the hydrogen storage bottle fixed base through the fixed base, the fixed rail is set in the second direction, the fixed table bottle mouth clamp is slidably connected to the fixed rail, and the fixed table bottle clamp driving mechanism is used to drive the two fixed table bottle mouth clamps to move closer to or away from each other at the same time.

[0013] By adopting this technical solution, the combination of a fixed base and a fixed track allows the fixed-base bottle-neck clamp to slide on the fixed track, thereby accommodating different sizes of Type III bottle necks. The fixed-base bottle-neck clamp drive mechanism can simultaneously drive the two fixed-base bottle-neck clamps toward or away from each other, ensuring evenly distributed clamping force and preventing the bottle neck from shifting or deforming during processing.

[0014] Optionally, the mobile bench clamp includes a mobile base, a mobile rail, two mobile bottle mouth clamps and a mobile bottle clamp driving mechanism, the mobile rail is slidably connected to the main slide through the mobile base, the mobile rail is arranged along the second direction, the mobile bottle mouth clamp is slidably connected to the mobile rail, and the mobile bottle clamp driving mechanism is used to drive the two mobile bottle mouth clamps to move closer to or away from each other at the same time.

[0015] By adopting the above technical solution, the combination of the mobile base and the mobile track enables the mobile platform bottle neck clamp to slide on the track to accommodate different sizes of Type III bottle necks. The mobile platform bottle neck clamp drive mechanism can drive the two mobile platform bottle neck clamps towards or away from each other simultaneously, ensuring evenly distributed clamping force and preventing the bottle neck from shifting or deforming during processing.

[0016] Optionally, the positioning end head includes a positioning base, an end head seat and a buffer head, the positioning base is fixedly connected to the movable base, the end head seat is fixedly connected to the positioning base, the end head seat is arranged along the first direction, the buffer head is slidably connected to the end head seat, and an elastic member is provided at the end of the buffer head away from the main shaft.

[0017] By adopting this technical solution, the fixed connection between the positioning base and the end head seat ensures the overall stability of the positioning end head. The sliding connection between the buffer head and the end head seat allows the buffer head to move within a certain range, thereby accommodating Type IV bottles of different sizes. The elastic member is located at the end of the buffer head away from the main shaft, which can provide an appropriate buffering effect, offsetting some of the force applied by the main shaft on the Type IV bottle, thereby reducing the force applied by the indexing vise on the Type IV bottle body, preventing damage to the Type IV bottle due to excessive clamping force during processing. Especially in the case of fragile plastic bottles, it effectively protects various parts of the bottle body from damage or deformation.

[0018] Optionally, the indexing bench vise includes an indexing platform, an indexing mechanism, an indexing track, two bottle body clamps and an indexing bench bottle clamp driving mechanism. The indexing mechanism is slidably connected to the main slide through the indexing platform. The indexing mechanism is used to drive the indexing track to rotate around the vertical direction. The bottle body clamp is slidably connected to the indexing track. The indexing bench bottle clamp driving mechanism is used to drive the two bottle body clamps to move closer to or away from each other at the same time.

[0019] By adopting this technical solution, the combination of the indexing platform and the indexing track allows the bottle clamps to slide on the indexing track to accommodate different sizes of Type IV bottles. The indexing platform bottle clamp drive mechanism can drive the two bottle clamps towards or away from each other simultaneously, ensuring evenly distributed clamping force and preventing the bottle from shifting or deforming during processing.

[0020] Optionally, the spindle system also includes a machining tool magazine, which includes a frame, a tool disc and a tool changing arm. The frame is arranged on one side of the spindle system, the tool disc is connected to the frame so as to be rotatable around its own axis, and the tool changing arm is connected to the frame so as to be reciprocating along the first direction. The axis of the tool changing arm is arranged along the first direction, and the tool changing arm is able to rotate around its own axis.

[0021] By adopting the above technical solution and equipping a processing tool magazine to store processing tools suitable for Type III and Type IV bottles of different materials, it is easy to replace the tools compatible with the spindle box, thereby realizing the bottle mouth thread processing and surface finishing of the two types of bottles.

[0022] Optionally, the machining tool magazine also includes a tool changing drive mechanism, which includes a tool disc motor for driving the tool disc to rotate around its own axis, a tool changing motor for driving the tool changing arm to rotate around its own axis, and a tool changing push rod for driving the tool changing arm to reciprocate along the first direction.

[0023] By adopting this technical solution, the tool change drive mechanism uses the cutterhead motor to rotate the cutterhead around its axis, quickly positioning the required tool and reducing tool change time. The tool change motor drives the tool change arm to rotate around its axis, ensuring accurate tool alignment or clearing the spindle's movement space when a tool change is not required. The tool change push rod drives the tool change arm back and forth in a first direction, pulling the tool out from the spindle or inserting it into the cutterhead, significantly improving tool change efficiency. This allows for automatic tool switching based on preset process parameters.

[0024] Optionally, a cooling system is further included, which includes a water chiller and an alcohol atomizer, and the spindle box is connected to the water chiller and the alcohol atomizer through a cooling water pipe and an atomizing air pipe respectively.

[0025] By implementing the above technical solutions, precise cooling of Type III and Type IV bottles is achieved. Specifically, the use of a water chiller for metal processing of Type III bottles effectively reduces heat generated during the cutting process, preventing deformation or heat treatment effects caused by high temperatures, thereby ensuring processing accuracy and quality while saving costs. For plastic processing of Type IV bottles, alcohol atomization refrigeration is used to precisely control temperature, preventing deformation or damage to the plastic bottle neck due to overheating, and ensuring processing quality and stability.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. One machine for multiple uses, improving production efficiency: This application is compatible with both Type III and Type IV hydrogen storage cylinders.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a special machine for processing bottle mouths for both Type III bottles and Type IV bottles.

[0038] like Figure 1As shown, the bottle mouth processing machine for both Type III and Type IV bottles includes a spindle system, which includes a spindle box 1 and a moving mechanism.

Similarly, the longitudinal moving component includes a longitudinal drive motor 5, a longitudinal rail 6 and a second screw 7 arranged in a second direction, the vertical rail 3 is slidably connected to the longitudinal rail 6, the second screw 7 is arranged on the longitudinal rail 6 and can rotate around its own axis in the second direction and is threadedly connected to the vertical rail 3, the body of the longitudinal drive motor 5 is fixedly connected to the longitudinal rail 6, and the output end of the longitudinal drive motor 5 is drivingly connected to the second screw 7 to drive the second screw 7 to rotate around its central axis.

[0040] During actual use: When the vertical drive motor 2 is started, the first screw 4 starts to rotate, and due to the meshing action of the threads, the spindle box 1 moves up and down in the vertical direction on the vertical rail 3. When the longitudinal drive motor 5 is started, the second screw 7 starts to rotate, and the vertical rail 3 slides along the second direction on the longitudinal rail 6, realizing the longitudinal movement of the vertical moving assembly. When the transverse drive motor 8 is started, the third screw 11 starts to rotate, and the longitudinal rail 6 slides along the first direction on the transverse rail 10, realizing the transverse movement of the longitudinal moving assembly and the vertical moving assembly as a whole. Through the coordinated work of the three moving assemblies, the moving mechanism can realize arbitrary movement of the spindle box 1 in three-dimensional space.

[0041] like Figure 1As shown, the bottle mouth processing machine for both type III and type IV bottles includes a hydrogen storage bottle fixing table 12, on which a main slide 13, a type III bottle clamp system and a type IV bottle clamp system are provided. The main slide 13 is arranged along a first direction, and the type III bottle clamp system includes a fixed vise 16 and a movable vise 17. The fixed vise 16 is fixedly connected to the hydrogen storage bottle fixing table 12, and the movable vise 17 is slidably connected to the main slide 13.

The Type IV bottle clamp system includes an indexing vise 19 and a positioning end 18. The indexing vise 19 is slidably connected to the main slide 13 and is located between the fixed vise 16 and the mobile vise 17. The positioning end 18 is fixedly connected to the mobile vise 17 and is located on the side of the mobile vise 17 away from the fixed vise 16. The indexing vise 19 is used to clamp and position the bottle body of the Type IV bottle, and the positioning end 18 is used to abut and position the end of the Type IV bottle away from the spindle box 1. The main slide 13 is arranged along the first direction to facilitate the transportation and positioning of the hydrogen storage bottle. The Type III bottle clamp system and the Type IV bottle clamp system can respectively achieve the clamping and positioning of Type III and Type IV hydrogen storage cylinders, thereby avoiding the need for users to purchase two independent sets of equipment and significantly reducing equipment investment costs.

[0042] In order to drive the mobile vise 17 and the indexing vise 19 to move along the main slide 13, a mobile platform drive mechanism and an indexing platform drive mechanism are further provided on the hydrogen storage bottle fixing platform 12. In this embodiment, the mobile platform drive mechanism may include a first drive cylinder 14, the body of the first drive cylinder 14 is fixedly connected to the hydrogen storage bottle fixing platform 12, and the output end of the first drive cylinder 14 is connected to the mobile vise 17 to drive the mobile vise 17 to reciprocate along the extension direction of the main slide 13, that is, the first direction. Similarly, in this embodiment, the indexing platform drive mechanism may include a second drive cylinder 15, the body of the second drive cylinder 15 is fixedly connected to the hydrogen storage bottle fixing platform 12, and the output end of the second drive cylinder 15 is connected to the indexing vise 19 to drive the indexing vise 19 to reciprocate along the extension direction of the main slide 13, that is, the first direction. The setting of the moving table drive mechanism and the indexing table drive mechanism enables the equipment to automatically control the rapid adjustment and movement of the fixture, while achieving precise control of the moving distance, ensuring the accurate positioning and stable clamping of Type III and Type IV bottles during the processing process, and improving the processing accuracy and quality.

[0043] The fixed table vise 16 of the Type III bottle clamp system includes a fixed base 1601, a fixed rail 1602, two fixed table bottle mouth clamps 1603 and a fixed table bottle clamp driving mechanism. The fixed rail 1602 is fixedly connected to the hydrogen storage bottle fixed base 12 through the fixed base 1601. The fixed rail 1602 is set in the second direction. The fixed table bottle mouth clamp 1603 is slidably connected to the fixed rail 1602. The fixed table bottle clamp driving mechanism is used to drive the two fixed table bottle mouth clamps 1603 to approach or move away from each other at the same time.

[0044] In this embodiment, the fixed platform bottle clamp drive mechanism may include a fixed platform bidirectional lead screw 1604, a fixed platform bevel gear structure, and a fixed platform auxiliary motor 1606. The fixed platform bidirectional lead screw 1604 is arranged on the fixed track 1602 along the second direction and is capable of rotating around its own axis. The center position of the fixed platform bidirectional lead screw 1604, i.e., the position where the rotation direction changes, is located at the center of the fixed track 1602. The two fixed platform bottle clamps 1603 are respectively threadedly connected to two opposite threaded sections of the fixed platform bidirectional lead screw 1604. The fixed platform auxiliary motor 1606 is drivingly connected to the fixed platform bidirectional lead screw 1604 via the fixed platform bevel gear structure to drive the fixed platform bidirectional lead screw 1604 to rotate around its own axis. The fixed platform bevel gear structure includes a fixed platform transmission rod 1605, which is arranged in the fixed platform base 1601 along the vertical direction and can rotate around its own axis. The output end of the fixed platform auxiliary motor 1606 is provided with a fixed platform active bevel gear 1607, and the center position of the fixed platform bidirectional screw 1604 is provided with a fixed platform driven bevel gear 1608. The two ends of the fixed platform transmission rod 1605 are respectively provided with a fixed platform first transmission bevel gear 1609 for engaging with the fixed platform active bevel gear 1607 and a fixed platform second transmission bevel gear 1610 for engaging with the fixed platform driven bevel gear 1608.

[0045] By combining fixed base 1601 with fixed track 1602, fixed platform bottle neck clamps 1603 can slide on fixed track 1602, thereby adapting to different sizes of Type III bottle necks. The design of the drive mechanism of fixed platform bottle neck clamps 1603 enables the two fixed platform bottle neck clamps 1603 to move toward or away from each other synchronously, ensuring even distribution of clamping force and effectively preventing deviation or deformation of the bottle neck during processing.

[0046] The movable table vise 17 of the Type III bottle clamp system includes a movable table 1701, a movable rail 1702, two movable table bottle mouth clamps 1703 and a movable table bottle clamp driving mechanism. The movable rail 1702 is slidably connected to the main slide 13 through the movable table 1701. The movable rail 1702 is arranged along the second direction. The movable table bottle mouth clamp 1703 is slidably connected to the movable rail 1702. The movable table bottle clamp driving mechanism is used to drive the two movable table bottle mouth clamps 1703 to move closer to or away from each other at the same time.

[0047] In this embodiment, the movable platform bottle clamp drive mechanism may include a movable platform bidirectional lead screw 1704, a movable platform bevel gear structure, and a movable platform auxiliary motor 1706. The movable platform bidirectional lead screw 1704 is disposed along the second direction at the movable track 1702 and is capable of rotating about its own axis. The center position of the movable platform bidirectional lead screw 1704, i.e., the position where the rotation direction changes, is disposed at the center of the movable track 1702. The two movable platform bottle clamps 1703 are respectively threadedly connected to two opposite threaded sections of the movable platform bidirectional lead screw 1704. The movable platform auxiliary motor 1706 is drivingly connected to the movable platform bidirectional lead screw 1704 via the movable platform bevel gear structure to drive the movable platform bidirectional lead screw 1704 to rotate about its own axis. The movable platform bevel gear structure includes a movable platform transmission rod 1705, which is arranged in the movable platform base 1701 along the vertical direction and can rotate around its own axis. The output end of the movable platform auxiliary motor 1706 is provided with a movable platform active bevel gear 1707, and the center position of the movable platform bidirectional lead screw 1704 is provided with a movable platform driven bevel gear 1708. The two ends of the movable platform transmission rod 1705 are respectively provided with a movable platform first transmission bevel gear 1709 for engaging with the movable platform active bevel gear 1707 and a movable platform second transmission bevel gear 1710 for engaging with the movable platform driven bevel gear 1708.

[0048] The combined design of the mobile platform 1701 and the mobile track 1702 enables the sliding of the mobile platform bottle neck clamp 1703 on the mobile track 1702 to accommodate the various sizes of Type III bottle necks. The design of the mobile platform bottle neck clamp drive mechanism enables the two mobile platform bottle neck clamps 1703 to move together and apart synchronously, ensuring even distribution of clamping force and effectively preventing deviation or deformation of the bottle neck during processing.

[0049] The positioning endpiece 18 of the Type IV bottle clamp system includes a positioning base 1801, an endpiece base 1802, and a buffer head 1803. Positioning base 1801 is fixedly connected to movable base 1701, while endpiece base 1802 is fixedly connected to positioning base 1801. Endpiece base 1802 is positioned along a first direction. Buffer head 1803 is slidably connected to endpiece base 1802. An elastic member is provided on the end of buffer head 1803 away from the main shaft. In this embodiment, the elastic member is a spring 1804.

[0050] The fixed connection between positioning base 1801 and end head seat 1802 ensures the overall stability of positioning end head 18. The sliding connection between buffer head 1803 and end head seat 1802 allows buffer head 1803 to move within a certain range, thereby accommodating Type IV bottles of different sizes. An elastic member is disposed on the side of buffer head 1803 away from the spindle. Its function is to provide the necessary buffering effect to offset some of the force applied by the spindle to the Type IV bottle, thereby reducing the clamping force required by the indexing vise 19 on the Type IV bottle. This effectively prevents damage to the Type IV bottle caused by excessive clamping force during processing, especially in the case of relatively fragile plastic bottles, and can fully protect various parts of the bottle body 28 from pressure damage or deformation.

[0051] The indexing vise 19 of the Type IV bottle clamp system includes an indexing platform 1901, an indexing mechanism, an indexing track 1902, two bottle body clamps 1903 and an indexing platform bottle clamp driving mechanism. The indexing mechanism is slidably connected to the main slide 13 through the indexing platform 1901. The indexing mechanism is used to drive the indexing track 1902 to rotate in a vertical direction. The bottle body clamp 1903 is slidably connected to the indexing track 1902. The indexing platform bottle clamp driving mechanism is used to drive the two bottle body clamps 1903 to move closer to or away from each other at the same time.

[0052] To adjust the coaxiality of the four-type bottle and the spindle system, the bottle body clamp 1903 may include a clamp base 19031, a clamp body 19032, and a swing motor 19033. The clamp base 19031 is slidably connected to the indexing track 1902. The body of the swing motor 19033 is fixed to the clamp base 19031. The output end of the swing motor 19033 is arranged along a first direction and is drivingly connected to the clamp body 19032. The clamp body 19032 is provided with a rubber pad 19034. To disperse stress, the bottle body clamp 19033 may include multiple swing motors 19033 and clamp bodies 19032.

[0053] In this embodiment, the indexing platform bottle clamp drive mechanism may include an indexing platform bidirectional lead screw 1904 and an indexing platform auxiliary motor 1905. The indexing platform bidirectional lead screw 1904 is disposed along the second direction on the indexing track 1902 and is capable of rotating about its own axis. The center of the indexing platform bidirectional lead screw 1904, i.e., the location where the rotational direction changes, is located at the center of the indexing track 1902. Two clamp seats 19031 are respectively threadedly connected to two opposite threaded sections of the indexing platform bidirectional lead screw 1904. The indexing platform auxiliary motor 1905 is drivingly connected to the indexing platform bidirectional lead screw 1904 to drive the indexing platform bidirectional lead screw 1904 to rotate about its own axis. There may be multiple indexing platform bidirectional lead screws 1904, and the number of indexing platform auxiliary motors 1905 is the same as the number of indexing platform bidirectional lead screws 1904.

[0054] The indexing mechanism may include an indexing motor 1906, an indexing turbine 1907 and an indexing worm 1908. The axis of the indexing turbine 1907 is arranged in the vertical direction and coincides with the center position of the bidirectional lead screw 1904 of the indexing table. The indexing turbine 1907 is rotatable around its own axis and is arranged in the indexing table 1901, and is driven and connected to the indexing track 1902. The body of the indexing motor 1906 is fixedly connected to the indexing table 1901, and the output end of the indexing motor 1906 extends into the indexing table 1901 and is driven and connected to the indexing worm 1908. The indexing worm 1908 cooperates with the indexing turbine 1907.

[0055] The combination of indexing platform 1901 and indexing track 1902 allows bottle clamps 1903 to slide on indexing track 1902 to accommodate different sizes of Type IV bottles. The indexing platform bottle clamp drive mechanism can drive the two bottle clamps 1903 toward or away from each other simultaneously, ensuring evenly distributed clamping force and preventing bottle displacement or deformation during processing.

[0056] The spindle system may also include a machining tool magazine, which includes a frame 20, a tool disc 21, a tool change arm 22, and a tool change drive mechanism. The frame 20 is disposed on one side of the spindle system. The tool disc 21 is connected to the frame 20 so as to be rotatable about its own axis. The tool change arm 22 is connected to the frame 20 so as to be reciprocatingly movable in a first direction. The axis of the tool change arm 22 is disposed along the first direction, and the tool change arm 22 is rotatable about its own axis. The tool change drive mechanism includes a tool disc 21 motor (not shown in the figure) for driving the tool disc 21 to rotate about its own axis, a tool change motor 23 for driving the tool change arm 22 to rotate about its own axis, and a tool change push rod (not shown in the figure) for driving the tool change arm 22 to reciprocate in the first direction.

[0057] By equipping a processing tool magazine, processing tools suitable for different materials of type III and type IV bottles can be stored, which facilitates the replacement of tools compatible with the spindle box 1 to achieve bottle mouth thread processing and surface finishing of the two types of bottle bodies 28. The tool change drive mechanism uses the cutter disc 21 motor to drive the cutter disc 21 to rotate around its axis to quickly position the required tool, thereby reducing tool change time. The tool change motor 23 drives the tool change arm 22 to rotate around its axis to ensure the precise docking of the tool, or when there is no need to change the tool, to make the tool avoid the movement space of the spindle. The tool change push rod drives the tool change arm 22 to move back and forth in the first direction to complete the action of pulling the tool outward from the spindle or feeding the tool into the cutter disc 21, significantly improving the tool change efficiency. Therefore, the device can automatically switch tools according to the preset process parameters.

[0058] The bottle mouth processing machine for both Type III and Type IV bottles can also include a cooling system, which includes a chiller 24 and an alcohol atomizer 25. The spindle box 1 is connected to the chiller 24 and the alcohol atomizer 25 through a cooling water pipe 26 and an atomizing air pipe 27 respectively.

[0059] The cooling system achieves precise temperature control during the processing of Type III and Type IV bottles. Specifically, during the metal processing of Type III bottles, the cooling mechanism of the chiller 24 effectively reduces the heat generated during cutting, thereby preventing deformation of the bottle body 28 due to high temperatures or adverse effects during the heat treatment process, while ensuring processing accuracy and quality while saving costs. For the plastic processing of Type IV bottles, alcohol atomization refrigeration technology is used to achieve precise temperature control, preventing deformation or damage to the plastic bottle mouth due to overheating during processing, and ensuring the quality and stability of the plastic bottle mouth processing.

[0060] In order to realize automatic control, the bottle mouth processing machine used for both type III and type IV bottles may also include a control system, which is connected to the spindle system, type III bottle clamp system, type IV bottle clamp system, moving table drive mechanism and indexing table drive mechanism by signal.

[0061] By adopting the above-mentioned technical solution and introducing a control system, the dedicated machine is able to achieve precise control of the spindle box 1, spindle system, Type III bottle clamping system, Type IV bottle clamping system, movable table drive mechanism, and indexing table drive mechanism, thereby improving the equipment's level of automation. This not only reduces the need for manual intervention but also significantly improves the stability and consistency of processing. The control system can automatically adjust the position and motion trajectory of the spindle box 1 according to different processing requirements, ensuring precise positioning and processing accuracy of Type III and Type IV bottles during processing. At the same time, through linkage with the movable table drive mechanism and indexing table drive mechanism, it achieves rapid adaptation and optimized processing of bottles 28 of different materials.

[0062] In addition, it can also prevent potential safety hazards caused by misoperation, such as reducing damage to the bottle or operator due to improper operation through special machine action interlock. The special machine action interlock includes the following conditions:

[0063] Condition 1

[0064] The movable clamp 17 is loosened (the distance between the two movable bottle clamps 1703 is the maximum distance)

[0065] The indexing base 1901 is in the front (the indexing base 1901 is located closest to the fixed base 1601 under the action of the second driving cylinder 15)

[0066] The first driving cylinder 14 can drive the movable base 1701 to move along the first direction;

[0067] Condition 2

[0068] Loosen the fixed clamp 16 (the distance between the two fixed bottle clamps 1603 is the maximum distance)

[0069] The movable clamp 17 is loosened (the distance between the two movable bottle clamps 1703 is the maximum distance)

[0070] The movable base 1701 is at the rear (the movable base 1701 is located at the position farthest from the fixed base 1601 under the action of the first driving cylinder 14)

[0071] The second driving cylinder 15 can drive the indexing platform 1901 to move along the first direction;

[0072] Condition 3

[0073] The indexing base 1901 is at the rear (the indexing base 1901 is located farthest from the fixed base 1601 under the action of the second driving cylinder 15)

[0074] The indexing mechanism can drive the indexing track 1902 to rotate in the vertical direction.

[0075] The implementation principle of a special machine for processing the bottle mouths of both Type III and Type IV bottles according to an embodiment of the present application is as follows: clamping and positioning of Type III and Type IV bottles, fixture driven movement, indexing positioning, and automatic tool change and processing cooling. Type III bottles are positioned by clamping the bottle mouths, while Type IV bottles are positioned by a fixture system including an indexing vise 19 and a positioning end 18. The fixed vise 16, the mobile vise 17, and the indexing vise 19 respectively realize the movement of the clamps and the adjustment of the clamping force through the fixed bottle clamp drive mechanism, the mobile bottle clamp drive mechanism, and the indexing bottle clamp drive mechanism. The indexing vise 19 is used for clamping and positioning the bottle body, and the positioning end 18 is used for abutment positioning of the bottle end. The arrangement of the main slide 13 is conducive to the transportation and positioning of hydrogen storage bottles. The design of the Type III bottle clamp system ensures adaptability to bottle mouths of different sizes and prevents offset or deformation during processing. The buffer head 1803 of the Type IV bottle clamp system provides the necessary buffering effect to reduce the clamping force. The indexing mechanism drives the indexing track 1902, achieving synchronous rotation of the bottle clamp 1903, thereby steering the bottle 28. The tool magazine is equipped with tools suitable for different materials, enabling rapid tool changes. The cooling system uses a chiller 24 and an alcohol atomizer 25 to control the temperature during the machining process. The control system achieves automated and precise control of the equipment, and interlocking mechanisms prevent misoperation.

[0076] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
