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 bottle mouth processing that is used for both Type III bottles and Type IV bottles. Background Art

[0002] In the current hydrogen storage cylinder manufacturing field, 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 bottles have different structures and their material properties are also quite different, so the process requirements for bottle mouth processing are different. Type III hydrogen storage cylinders have good strength and corrosion resistance because their liner is made of aluminum alloy. The bottle mouth is usually processed by mechanical processing, and precision thread cutting is required on high-strength metal materials, which requires mechanical processing equipment to have high precision and cutting force. The liner of Type IV hydrogen storage cylinders is plastic, the overall weight of the bottle is lighter, and the processing method of the bottle mouth is more special. Plastic materials are highly heat-sensitive during processing and are easily deformed by temperature, so higher control requirements are placed on processing temperature and cutting force.

[0003] In order to meet the processing requirements of different types of hydrogen storage cylinders, the relevant technical solutions mainly include: First, design different special equipment for type III and type IV bottles. Although this approach can better meet the respective processing requirements, it also brings problems such as a wide variety of equipment and complex maintenance. Second, general equipment is used for processing, but it requires frequent tool changes and parameter adjustments, resulting in low production efficiency and unstable processing quality.

[0012] By adopting the above technical solution, the combination of the fixed platform and the fixed track enables the fixed platform bottle mouth clamp to slide on the fixed track, thereby adapting to the different sizes of Type III bottle mouths. The fixed platform bottle mouth clamp driving mechanism can drive the two fixed platform bottle mouth clamps to move closer or farther from each other at the same time, ensuring that the clamping force is evenly distributed and preventing the bottle mouth from shifting or deforming during the processing process.

[0014] By adopting the above technical solution, the combination of the mobile base and the mobile track enables the mobile table bottle mouth clamp to slide on the mobile track, thereby adapting to the different sizes of type III bottle mouths. The mobile table bottle mouth clamp driving mechanism can drive the two mobile table bottle mouth clamps to move closer or farther from each other at the same time, ensuring that the clamping force is evenly distributed and preventing the bottle mouth from shifting or deforming during the processing process.

[0015] 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.

[0016] By adopting the above technical solution, the fixed connection between the positioning base and the end head seat ensures the overall stability of the positioning end head, and the sliding connection between the buffer head and the end head seat allows the buffer head to move within a certain range, so as to adapt to different sizes of type IV bottles. The elastic member is arranged at the end of the buffer head away from the main shaft, which can provide appropriate buffering effect, offset part 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 relatively fragile plastic bottles, effectively protecting various parts of the bottle body from pressure damage or deformation.

[0017] 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.

[0022] By adopting the above technical solution, the tool change drive mechanism drives the tool disc to rotate around its own axis through the tool disc motor, quickly locates the required tool, and reduces the tool change time. The tool change motor drives the tool change arm to rotate around its own axis to ensure that the tool is accurately docked or avoids the movement space of the spindle when there is no need to change the tool. The tool change push rod drives the tool change arm to move back and forth in the first direction to achieve the action of pulling the tool out from the spindle or sending the tool into the tool disc, which significantly improves the tool change efficiency. In this way, the tool can be automatically switched according to the preset process parameters.

[0023] Optionally, a cooling system is also 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.

Specifically: the metal processing of type III bottles uses a water chiller to effectively reduce the heat generated during the cutting process, prevent the bottle body from being deformed or affected by heat treatment due to high temperature, and ensure processing accuracy and quality while saving costs. The plastic processing of type IV bottles uses alcohol atomization cooling to accurately control the temperature, avoid deformation or damage of the plastic bottle mouth due to overheating, and ensure the processing quality and stability of the plastic bottle mouth.

When the transverse drive motor 8 is started, the third screw 11 starts to rotate, and the longitudinal rail 6 slides on the transverse rail 10 in the first direction, thereby 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 any movement of the spindle box 1 in three-dimensional space.

[0037] 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, the movable vise 17 is slidably connected to the main slide 13, and the movable vise 17 is located on a side of the fixed vise 16 away from the spindle box 1, and the fixed vise 16 and The mobile vise 17 is used to clamp and position the mouth of the Type III bottle.

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 realize the clamping and positioning of Type III and Type IV hydrogen storage cylinders, thereby avoiding the need for users to purchase two sets of independent equipment and significantly reducing the equipment investment cost.

[0038] In order to drive the mobile bench vise 17 and the indexing bench vise 19 to move along the main slide 13, a mobile table driving mechanism and an indexing table driving mechanism are also provided on the hydrogen storage bottle fixing platform 12. In this embodiment, the mobile table driving mechanism may include a first driving cylinder 14, the body of the first driving cylinder 14 is fixedly connected to the hydrogen storage bottle fixing platform 12, and the output end of the first driving cylinder 14 is connected to the mobile bench vise 17 to drive the mobile bench vise 17 to reciprocate along the extension direction of the main slide 13, that is, the first direction. Similarly, in this embodiment, the indexing table driving mechanism may include a second driving cylinder 15, the body of the second driving cylinder 15 is fixedly connected to the hydrogen storage bottle fixing platform 12, and the output end of the second driving cylinder 15 is connected to the indexing bench vise 19 to drive the indexing bench vise 19 to reciprocate along the extension direction of the main slide 13, that is, the first direction.

[0039] The fixed bench vise 16 of the Type III bottle clamp system includes a fixed base 1601, a fixed rail 1602, two fixed base bottle mouth clamps 1603 and a fixed base 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 base bottle mouth clamp 1603 is slidably connected to the fixed rail 1602. The fixed base bottle clamp driving mechanism is used to drive the two fixed base bottle mouth clamps 1603 to move closer to or away from each other at the same time.

[0040] In this embodiment, the fixed platform bottle clamp driving 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 at the fixed track 1602 along the second direction and the fixed platform bidirectional lead screw 1604 can rotate 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 arranged at the center of the fixed track 1602. The two fixed platform bottle mouth clamps 1603 are respectively threadedly connected with two opposite thread segments of the fixed platform bidirectional lead screw 1604. The fixed platform auxiliary motor 1606 is drivingly connected with the fixed platform bidirectional lead screw 1604 through 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 seat 1601 along the vertical direction and can rotate around its own axis direction. 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 lead 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 meshing with the fixed platform active bevel gear 1607 and a fixed platform second transmission bevel gear 1610 for meshing with the fixed platform driven bevel gear 1608.

[0041] By combining the fixed base 1601 and the fixed track 1602, the fixed platform bottle mouth clamp 1603 can slide on the fixed track 1602, thereby adapting to the different sizes of type III bottle mouths. The design of the fixed platform bottle mouth clamp 1603 driving mechanism enables the two fixed platform bottle mouth clamps 1603 to move closer to or farther from each other synchronously, ensuring the uniform distribution of the clamping force and effectively preventing the deviation or deformation of the bottle mouth during the processing.

[0042] The mobile table clamp 17 of the type III bottle clamp system includes a mobile table 1701, a mobile track 1702, two mobile table bottle mouth clamps 1703 and a mobile table bottle clamp driving mechanism.

The mobile table bottle mouth clamp 1703 is slidably connected to the mobile track 1702. The mobile table bottle clamp driving mechanism is used to drive the two mobile table bottle mouth clamps 1703 to move closer to or away from each other at the same time.

[0043] In this embodiment, the mobile platform bottle clamp driving mechanism may include a mobile platform bidirectional lead screw 1704, a mobile platform bevel gear structure, and a mobile platform auxiliary motor 1706. The mobile platform bidirectional lead screw 1704 is arranged at the mobile track 1702 along the second direction and the mobile platform bidirectional lead screw 1704 can rotate around its own axis. The center position of the mobile platform bidirectional lead screw 1704, that is, the position where the rotation direction changes, is arranged at the center of the mobile track 1702. The two mobile platform bottle mouth clamps 1703 are respectively threadedly connected with two opposite thread segments of the mobile platform bidirectional lead screw 1704. The mobile platform auxiliary motor 1706 is drivingly connected to the mobile platform bidirectional lead screw 1704 through the mobile platform bevel gear structure to drive the mobile platform bidirectional lead screw 1704 to rotate around its own axis. The mobile platform bevel gear structure includes a mobile platform transmission rod 1705, which is arranged in the mobile platform base 1701 along the vertical direction and can rotate around its own axis direction. The output end of the mobile platform auxiliary motor 1706 is provided with a mobile platform active bevel gear 1707, and the center position of the mobile platform bidirectional lead screw 1704 is provided with a mobile platform driven bevel gear 1708. The two ends of the mobile platform transmission rod 1705 are respectively provided with a mobile platform first transmission bevel gear 1709 for meshing with the mobile platform active bevel gear 1707 and a mobile platform second transmission bevel gear 1710 for meshing with the mobile platform driven bevel gear 1708.

[0044] Through the combined design of the mobile platform 1701 and the mobile track 1702, the sliding function of the mobile platform bottle mouth clamp 1703 on the mobile track 1702 is realized to adapt to the bottle mouths of type III bottles of different specifications. The design of the mobile platform bottle mouth clamp driving mechanism enables the two mobile platform bottle mouth clamps 1703 to synchronously approach or separate, ensuring the uniform distribution of the clamping force and effectively preventing the deviation or deformation of the bottle mouth during the processing.

[0045] The positioning end head 18 of the IV-type bottle clamp system includes a positioning base 1801, an end head seat 1802 and a buffer head 1803.

In this embodiment, the elastic member is a spring 1804.

[0046] The fixed connection between the positioning base 1801 and the end seat 1802 ensures the overall stability of the positioning end 18, and the sliding connection between the buffer head 1803 and the end seat 1802 allows the buffer head 1803 to move within a certain range, so as to adapt to different sizes of type IV bottles. The elastic member is arranged on the side of the buffer head 1803 away from the main shaft, and its function is to provide the necessary buffering effect to offset part of the force applied by the main shaft to the type IV bottle, thereby reducing the clamping force that the indexing vise 19 needs to apply to the type IV bottle. This effectively prevents damage to the type IV bottle due to excessive clamping force during the processing, especially when the plastic bottle material is relatively fragile, and can fully protect various parts of the bottle body 28 from pressure damage or deformation.

The indexing mechanism is used to drive the indexing track 1902 to rotate around the vertical direction. The bottle body clamp 1903 is slidably connected to the indexing track 1902. The indexing bench 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.

[0048] In order to adjust the coaxiality between the four-type bottle and the main axis system, the bottle body clamp 1903 may include a clamp seat 19031, a clamp body 19032 and a swing motor 19033. The clamp seat 19031 is slidably connected to the indexing track 1902. The body of the swing motor 19033 is fixed to the clamp seat 19031. The output end of the swing motor 19033 is arranged along the first direction and is drivingly connected to the clamp body 19032. The clamp body 19032 is provided with a rubber cushion 19034. In order to disperse stress, the bottle body clamp 1903 may include multiple swing motors 19033 and clamp bodies 19032.

[0049] In this embodiment, the indexing table bottle clamp driving mechanism may include an indexing table bidirectional lead screw 1904 and an indexing table auxiliary motor 1905. The indexing table bidirectional lead screw 1904 is arranged at the indexing track 1902 along the second direction and the indexing table bidirectional lead screw 1904 can rotate around its own axis. The center position of the indexing table bidirectional lead screw 1904, i.e., the position where the rotation direction changes, is arranged at the center of the indexing track 1902. The two clamp seats 19031 are respectively threadedly connected with two opposite thread segments of the indexing table bidirectional lead screw 1904. The indexing table auxiliary motor 1905 is drivingly connected with the indexing table bidirectional lead screw 1904 to drive the indexing table bidirectional lead screw 1904 to rotate around its own axis. There may be multiple indexing table bidirectional lead screws 1904, and the number of the indexing table auxiliary motors 1905 is the same as the number of the indexing table bidirectional lead screws 1904.

[0050] 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 base 1901, and is drivingly connected to the indexing track 1902. The body of the indexing motor 1906 is fixedly connected to the indexing base 1901, and the output end of the indexing motor 1906 extends into the indexing base 1901 and is drivingly connected to the indexing worm 1908. The indexing worm 1908 cooperates with the indexing turbine 1907.

[0051] The combination of the indexing platform 1901 and the indexing track 1902 enables the bottle body clamp 1903 to slide on the indexing track 1902, thereby adapting to different sizes of type IV bottles. The indexing platform bottle clamp driving mechanism can drive the two bottle body clamps 1903 to move closer or farther from each other at the same time, ensuring that the clamping force is evenly distributed and preventing the bottle body from being offset or deformed during the processing process.

[0052] 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 arranged on one side of the spindle system, the tool disc 21 is connected to the frame 20 so as to be rotatable around its own axis, the tool change arm 22 is connected to the frame 20 so as to be reciprocating along a first direction, the axis of the tool change arm 22 is arranged along the first direction, and the tool change arm 22 is rotatable around 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 around its own axis, a tool change motor 23 for driving the tool change arm 22 to rotate around its own axis, and a tool change push rod (not shown in the figure) for driving the tool change arm 22 to reciprocate along the first direction.

[0053] By equipping the processing tool magazine, processing tools suitable for different materials of type III and type IV bottles can be stored, which is convenient for replacing 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 locate the required tool, thereby reducing the 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, the tool is kept out of the movement space of the spindle. The tool change push rod drives the tool change arm 22 to reciprocate along 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 the tool according to the preset process parameters.

[0054] The bottle mouth processing machine for both type III and type IV bottles can also include a cooling system, which includes a water chiller 24 and an alcohol atomizer 25. The spindle box 1 is connected to the water chiller 24 and the alcohol atomizer 25 through a cooling water pipe 26 and an atomizing air pipe 27 respectively.

[0055] The cooling system achieves precise temperature control for 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 by cutting, thereby preventing the deformation of the bottle body 28 caused by high temperature or adverse effects during the heat treatment process, while ensuring the accuracy and quality of processing under the premise of cost savings. For the plastic processing of type IV bottles, alcohol atomization refrigeration technology is used to achieve precise temperature control, avoid deformation or damage of the plastic bottle mouth due to overheating during the processing, and ensure the quality and stability of the plastic bottle mouth processing.

[0056] In order to realize automatic control, the bottle mouth processing machine for both type III and type IV bottles can also include a control system, which is connected to the spindle system, type III bottle clamp system, type IV bottle clamp system, mobile table drive mechanism and indexing table drive mechanism by signal.

[0057] By adopting the above technical solution and introducing the control system, the special machine can realize precise control of the spindle box 1, the spindle system, the type III bottle fixture system, the type IV bottle fixture system, the mobile table drive mechanism and the indexing table drive mechanism, thereby improving the automation level of the equipment. 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 the precise positioning and processing accuracy of type III and type IV bottles during the processing. At the same time, through the linkage with the mobile table drive mechanism and the indexing table drive mechanism, rapid adaptation and optimized processing of bottles 28 of different materials are achieved.

[0058] In addition, it can also prevent potential safety hazards caused by misoperation, such as reducing damage to the bottle or operator caused by improper operation through special machine action interlock. The special machine action interlock includes the following conditions: Condition 1 The movable clamp 17 is loosened (the distance between the two movable clamps 1703 is the maximum distance) The indexing platform 1901 is in the front (the indexing platform 1901 is located closest to the fixed platform 1601 under the action of the second driving cylinder 15) The first driving cylinder 14 can drive the movable platform 1701 to move along the first direction; Condition 2 The fixed clamp 16 is loosened (the distance between the two fixed bottle clamps 1603 is the maximum distance) The movable clamp 17 is loosened (the distance between the two movable clamps 1703 is the maximum distance) 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) The second driving cylinder 15 can drive the indexing platform 1901 to move along the first direction; Condition 3 The indexing platform 1901 is at the rear (the indexing platform 1901 is located at the position farthest from the fixed platform 1601 under the action of the second driving cylinder 15) The indexing mechanism can drive the indexing track 1902 to rotate in the vertical direction.

[0059] The implementation principle of a special machine for processing the bottle mouths of type III and type IV bottles in the embodiment of the present application is as follows: clamping and positioning of type III and type IV bottles, fixture drive movement, indexing positioning, automatic tool change and processing cooling. Type III bottles are positioned by clamping the bottle mouth, 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 clamp 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 the hydrogen storage bottle. 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 to rotate, realizing the synchronous rotation of the bottle clamp 1903, thereby realizing the steering of the bottle body 28. The processing tool magazine is equipped with processing tools suitable for different materials to achieve rapid tool change. The cooling system controls the temperature of the processing process through the chiller 24 and the alcohol atomizer 25. The control system realizes automatic and precise control of the equipment and prevents misoperation through action interlocking.

[0060] 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.
