Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen energy vehicle fuel cell stack accessories manufacturing, and in particular to a hydrogen energy fuel cell air and fuel manifold machining device. Background Art

[0002] A hydrogen-powered car is a car that uses hydrogen as fuel. This car generates electricity by reacting hydrogen with oxygen in a fuel cell, which drives an electric motor to drive the vehicle. Compared with traditional fuel vehicles, hydrogen-powered cars have the advantages of zero emissions, high energy density, fast refueling and long driving range.

[0003] In hydrogen energy vehicles, the fuel cell stack group is generally composed of multiple fuel cell stacks with lower power, and a hydrogen energy fuel cell air and fuel manifold is required for gas distribution. The hydrogen energy fuel cell air and fuel manifold includes an air intake pipe, a fuel hydrogen intake pipe, and a distribution manifold corresponding to the number of fuel cell stacks. The distribution manifold is connected to the air intake pipe and the fuel hydrogen intake pipe, and the fuel hydrogen and air are mixed and distributed to the fuel cell stack. To adapt to different types of vehicles, technicians in this field have developed a variety of fuel cell stacks, and correspondingly developed a variety of hydrogen energy fuel cell air and fuel manifolds. During the manufacturing process of the hydrogen energy fuel cell air and fuel manifold, the blank is formed by casting, welding or 3D printing, and then the burrs are removed by sanding, and then the flange openings (air intake pipe flange, fuel hydrogen intake pipe flange, distribution manifold flange) are milled by a machining device.

[0004] Existing machining equipment mainly includes machine tools, which are equipped with tool heads for machining hydrogen energy fuel cell air and fuel manifolds, and tooling for fixing hydrogen energy fuel cell air and fuel manifolds. Since hydrogen energy fuel cell air and fuel manifolds are thin-walled, irregular and complex pipe structures, clamping is difficult, and the selection of clamping points and clamping forces is crucial. Different clamping mechanisms need to be selected according to the structure, size, shape, and processing method of hydrogen energy fuel cell air and fuel manifolds. To avoid the flatness and roughness of the processed products failing to meet the requirements of the drawings due to design errors in the clamping mechanism, the following requirements should be followed when selecting the clamping method, clamping structure, and clamping point position.

[0005] (1) The clamping mechanism should be selected according to the structural shape, relevant technical requirements and clamping form of the product, and can be spiral, hydraulic, pneumatic or other clamping forms.

[0006] (2) The clamping structure should be a linkage structure as much as possible to ensure that the clamping force obtained at each clamping point is balanced to avoid deformation of the workpiece due to excessive local clamping force.

[0007] (3) The clamping point should be selected at or close to the support point as much as possible to effectively reduce clamping deformation.

[0008] (4) When milling a plane, try not to choose a vertical clamping method, but a horizontal clamping method. When horizontal clamping is used, the front clamping point should be 2-5 mm lower than the rear support point to prevent the workpiece from lifting and leaving the horizontal positioning point during the clamping process, thereby affecting the processing quality. If vertical clamping is necessary, auxiliary supports should be set at the corresponding position of the clamping point to prevent the workpiece from being deformed due to excessive clamping force, which ultimately affects the processing quality.

[0009] (5) Positioning must be set in the X-axis of the fixture to prevent excessive cutting force due to local protrusions on the workpiece, causing the workpiece to move relative to the fixture in the X-axis, thereby avoiding poor processing quality, instability, tool hitting or workpiece flying out and injuring people.

[0010] (6) The clamping force should be 1.2-1.5 times the cutting force, and the stability of the clamping force should be controlled. The clamping force generated by hydraulic or pneumatic means is controllable, stable and reliable, which can avoid clamping deformation caused by improper clamping force or workpiece displacement caused by insufficient clamping force.

[0011] The structure and shape of the clamp body are determined according to the structure, size, shape, and precision requirements of the air and fuel manifolds of the hydrogen energy fuel cell, as well as the structure, size, and shape of each component of the fixture. Generally, the clamp body adopts a cast structure or structural steel, which has high compressive strength, good vibration resistance, easy processing, and low cost. The wall thickness of the clamp body is reasonably selected based on the cutting force, clamping force, processing machine tools, and tool materials. Arc angles are set at the corners, and annealing or stress relief treatment is used to ensure the rigidity and stability of the clamp body, as well as minimize the material cost. For hydraulic clamps, a split structure is used as much as possible to facilitate the standardization and modularization of the clamp parts, which can effectively reduce the manufacturing cost and manufacturing cycle of the clamp.

[0012] Based on the above-mentioned design requirements and concepts, technicians in this field have designed a variety of hydrogen energy fuel cell air and fuel manifold machining devices to meet processing needs and ensure product quality.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0027] Example 1 like Figure 1-4 As shown, a hydrogen energy fuel cell air and fuel manifold 3 machining device is used to process the air intake pipe flange 301, the fuel hydrogen intake pipe flange 302, and the distribution manifold flange 303 of the hydrogen energy fuel cell air and fuel manifold 3 with different directions, and to perform milling on the end faces of the air intake pipe flange 301, the fuel hydrogen intake pipe flange 302, and the distribution manifold flange 303, including a machine tool. In this embodiment, the machine tool is a CNC milling machine 1, and a tool head for machining the hydrogen energy fuel cell air and fuel manifold 3 is installed on the machine tool, and the tool head is a milling cutter head.

[0028] The machine tool is also equipped with a tool for fixing the hydrogen energy fuel cell air and fuel manifold 3, the tool includes a pre-positioning device, the pre-positioning device includes a support frame, the support frame is formed with a profiling portion 1 that matches the middle position of the hydrogen energy fuel cell air and fuel manifold 3, the hydrogen energy fuel cell air and fuel manifold 3 is fixed on the support frame, and the part to be processed is exposed. Specifically, the support frame includes a plurality of support blocks 5, the support blocks 5 are made of steel plates, and process holes are processed on the support blocks 5 to reduce weight. Two adjacent support blocks 5 are connected by a connecting frame. In this embodiment, the support blocks 5 are installed on the base plate 2, and the base plate 2 also forms a connecting frame, which is convenient for prefabrication and is fixed to the workbench of the machine tool through the base plate 2. A profiling groove 8 is cut or punched on the support block 5, and a plurality of profiling grooves 8 form a profiling portion 1, which adapts to the shape of the hydrogen energy fuel cell air and fuel manifold 3, supports the hydrogen energy fuel cell air and fuel manifold 3, increases the support area, and forms a flow gap between the adjacent two support blocks 5 to pass the processing coolant. During the machining process, coolant is used to cool the machining part and the cutter head. A positioning plate matched with the profiling part 1 is installed on the support frame. The positioning plate supports the hydrogen energy fuel cell air and fuel manifold 3 from the side. For the convenience of machining, there are two profiling parts 1 on the support frame of this embodiment. The two profiling parts 1 correspond to the two states to be machined of the hydrogen energy fuel cell air and fuel manifold 3, so that two hydrogen energy fuel cell air and fuel manifolds 3 can be placed. Correspondingly, there are two positioning plates, namely positioning plate 1 4 and positioning plate 2 9. Positioning plate 1 4 corresponds to the gas distribution manifold flange 303, and positioning plate 2 9 corresponds to the air intake pipe flange 301. After the hydrogen energy fuel cell air and fuel manifold 3 is placed on the support frame, the gas distribution manifold flange 303 and the air intake pipe flange 301 are fitted with the corresponding positioning plates. For faster positioning, hemispherical bosses 401 are fixed on the working surfaces of the positioning plates 1 4 and the positioning plates 2 9, which correspond to the corresponding pipe openings, and the position and angle of the hydrogen energy fuel cell air and fuel manifold 3 are adjusted to complete pre-positioning.

[0029] The tooling also includes a clamping device, which includes a mobile clamping head 6 installed on the machine tool. The mobile clamping head 6 is connected to a mobile driving device, and the mobile driving device is connected to a driving force control device. In this embodiment, the mobile driving device uses a hydraulic cylinder 7, and the hydraulic station that drives the hydraulic cylinder 7 to move forms a driving force control device, thereby controlling the stroke and clamping force of the hydraulic cylinder 7. The mobile clamping head 6 is processed with a second profiling portion that matches the hydrogen energy fuel cell air and fuel manifold 3. In this embodiment, the second profiling portion is a second profiling groove 23 processed on the mobile clamping head, which corresponds to the end shape of the hydrogen energy fuel cell air and fuel manifold 3. Since the hydrogen energy fuel cell air and fuel manifold 3 is placed on a support frame and is not fixed after pre-positioning, there are two mobile clamping heads 6, which move from both ends to fix the hydrogen energy fuel cell air and fuel manifold 3. During the action, the two hydraulic cylinders 7 are controlled by the hydraulic station to move synchronously, and then simultaneously press the hydrogen energy fuel cell air and fuel manifold 3 to fix it. After the fixation is completed, the machine tool controls the movement of the cutter head to perform milling processing.

[0030] Example 2 like Figure 5-7As shown, a hydrogen energy fuel cell air and fuel manifold 3 machining device is different from Example 1 in that a clamping frame 12 matched with a contoured portion 1 is installed on the support frame, and the connecting frame is composed of a connecting rod 13 group connected between two adjacent support blocks 5. The clamping frame 12 and the support frame are positioned by positioning pins and connected by bolts. A bracket matched with the support frame is installed on the machine tool, and the bracket includes two transverse support rods 11, and the support rods 11 are made of round steel. The ends of the support rods 11 are fixed to the workbench of the machine tool through a vertical frame 14. At least two sides of the support frame are processed with positioning grooves 10 matched with the bracket. The hydrogen energy fuel cell air and fuel manifold 3 is placed on the support frame, and after adjusting the position, it is clamped by the clamping frame 12, pre-installed outside the machine tool, and placed on the bracket after pre-installation. It is pre-positioned by the cooperation of the positioning grooves 10 and the support rods 11, and then clamped by the moving clamping head 6. In this embodiment, the moving clamping head 6 can clamp the support frame or the hydrogen energy fuel cell air and fuel. Material manifold 3, in order to facilitate the adjustment of hydrogen energy fuel cell air and fuel manifold 3, elastic pad 15 is attached to the inner surface of profiling groove 8, elastic pad 15 is selected from rubber pad, thickness 1-2mm, provides friction force in the initial stage, provides positioning in the process of adjusting the position and angle of hydrogen energy fuel cell air and fuel manifold 3, when the support frame and the pressing frame 12 are pressed, the rubber pad is completely squeezed and deformed to within 1mm, ensuring the rigid support of the support frame and the pressing frame 12 to the hydrogen energy fuel cell air and fuel manifold 3, the profiling part is connected with an anti-sequential movement structure matched with the hydrogen energy fuel cell air and fuel manifold 3, the anti-sequential movement structure includes a transverse threaded push rod 16 installed on the support frame, and the end of the threaded push rod 16 is provided with a head 17 matched with the hydrogen energy fuel cell air and fuel manifold 3, and the bending part of the hydrogen energy fuel cell air and fuel manifold 3 is tightly supported by the head 17 to prevent the hydrogen energy fuel cell air and fuel manifold 3 from moving along the profiling part, thereby ensuring the processing quality.

[0031] The hydrogen energy fuel cell air and fuel manifold 3 machining device provided in this embodiment first places the hydrogen energy fuel cell air and fuel manifold 3 on a support frame, adjusts the position and then presses it through a clamping frame 12, and then places the whole on the bracket, and presses it through a moving clamping head 6 to perform milling processing. When one surface to be processed is completed, the support frame is flipped over as a whole, and another set of positioning grooves 10 cooperates with the support rod 11, and then presses it through a moving clamping head 6 to process the second surface to be processed. There is no need for repeated positioning, and the positioning accuracy is higher than that of Example 1. By designing the shape of the support frame and the clamping frame 12, the position to be processed can be avoided, thereby ensuring the normal processing of the cutter head. The disadvantage is that the overall weight of the support frame, the clamping frame 12 and the hydrogen energy fuel cell air and fuel manifold 3 is heavy after being assembled together. Safety needs to be paid attention to during transportation and flipping. In order to reduce weight, process holes are processed on the support frame and the clamping frame 12 to reduce weight.

[0032] Example 3 like Figure 8-10 As shown, a hydrogen energy fuel cell air and fuel manifold 3 machining device, which is different from embodiment 1-2 in that the support frame is connected to a flip driving device, and a pressure block 29 matching the hydrogen energy fuel cell air and fuel manifold 3 is formed on the support frame at the side of the profiling groove 8, and a placement groove is formed between the pressure block 29 and the profiling groove 8. A prestressed device matching the placement groove is also installed on the support frame, and the prestressed device includes a swing arm 25 installed on the lower side of the profiling portion, and the free end of the swing arm 25 is processed with a bracket 26 matching the hydrogen energy fuel cell air and fuel manifold 3. The swing arm 25 is connected to a reset spring 28. When the hydrogen energy fuel cell air and fuel manifold 3 is placed in the placement groove, the swing arm 25 is pushed to deform the reset spring 28, thereby providing upward prestress. The prestress cooperates with the pressure block 29 to provide positioning in the process of adjusting the position and angle of the hydrogen energy fuel cell air and fuel manifold 3, and the moving pressure The clamping head 6 cooperates with the support frame through the movable pressure plate 22, and a return spring 24 is installed between the movable pressure plate 22 and the support frame. Under normal conditions, the return spring 24 drives the movable pressure plate 22 away from the profiling part 1, thereby ensuring that the hydrogen energy fuel cell air and fuel manifold 3 can be placed in the placement groove. The movable pressure plate 22 is fixed with a movable wedge 30 that cooperates with the swing arm 25 through the driving rod 27, and a guide hole that cooperates with the driving rod 27 is processed on the support block 5. When the movable pressure plate 22 is driven by the movable clamping head 6 to clamp the hydrogen energy fuel cell air and fuel manifold 3, the movable wedge 30 supports the swing arm 25, thereby converting the elastic support of the swing arm 25 to the hydrogen energy fuel cell air and fuel manifold 3 into a rigid support, and then cooperates with the movable pressure plate 22 to clamp the end of the hydrogen energy fuel cell air and fuel manifold 3 to ensure the clamping stability, thereby ensuring the stability of the milling process, and the profiling groove 23 is processed on the movable pressure plate 22.

[0033] The flipping drive device includes a vertical frame 20 fixed on the workbench of the machine tool, and a flipping drive motor 21 is installed on the vertical frame 20. The output shaft of the flipping drive motor 21 is connected to two connecting shafts 19 through a short shaft 18. The connecting shafts 19 are made of round steel. The two connecting shafts 19 form a connecting frame. The flipping drive motor 21 uses a servo motor, which can control the turning angle and then control the flipping angle of the support frame. To ensure stability, vertical frames 20 are installed at both ends of the support frame.

[0034] When in use, the flip drive device drives the support frame to flip to position one. In the position one state, the placement slot opens upward, and the hydrogen energy fuel cell air and fuel manifold 3 is placed in the placement slot. The prestressed device cooperates with the placement slot to perform preliminary clamping and positioning of the hydrogen energy fuel cell air and fuel manifold 3, and the hydrogen energy fuel cell air and fuel manifold 3 is adjusted to a predetermined position. The flip drive device drives the support frame to flip to position two, and the mobile pressing head 6 moves to press the hydrogen energy fuel cell air and fuel manifold 3 through the mobile pressing plate 22. In the position two state, at least one of the hydrogen energy fuel cell air and fuel manifold 3 is on standby. The processing part is directly opposite to the cutter head, and then the part to be processed is milled. After the processing is completed, the mobile clamping head 6 is reset, and the flipping drive device drives the support frame to flip to position three. The mobile clamping head 6 moves through the mobile pressure plate 22 to press the hydrogen energy fuel cell air and fuel manifold 3. In the position three state, the other waiting processing part of the hydrogen energy fuel cell air and fuel manifold 3 is directly opposite to the cutter head, and then the part to be processed is milled. After the processing is completed, the mobile clamping head 6 is reset, the flipping drive device is reset, and the hydrogen energy fuel cell air and fuel manifold 3 processed by the machine is taken out to complete the entire processing process.

[0035] Compared with Examples 1-2, the hydrogen energy fuel cell air and fuel manifold 3 machining device provided in this embodiment places the hydrogen energy fuel cell air and fuel manifold 3 to be machined, adjusts it, and then drives the support frame to flip through the flipping drive device. It has a high degree of automation, but the disadvantage is that the structure is relatively complex and requires regular debugging and maintenance.

[0036] The machining device for the hydrogen energy fuel cell air and fuel manifold 3 provided in the present application can be used to pre-position the hydrogen energy fuel cell air and fuel manifold 3 with complex structure, large size, thin wall thickness, irregular processing parts and heavy weight after it is placed on the tooling. Then, the position and angle are adjusted. After the adjustment is completed, it is clamped by the clamping device and then milling is performed to ensure product quality.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
