Description

Technical Field

[0001] This invention relates to the technical field of riveting equipment, and in particular to a core-pulling riveting device. Background Technology

[0002] In an era where transportation is increasingly moving towards three-dimensional and intelligent systems, flying cars have become a crucial carrier in future integrated transportation systems. Due to the need to navigate complex switching between aerial and ground scenarios, the structural materials of flying cars face extremely stringent requirements, simultaneously achieving multiple goals such as lightweight design, high strength, and adaptability to complex environments. Lightweight design reduces energy consumption during flight and improves range; high strength ensures the safety of flying cars during high-speed flight and on complex road conditions; and adaptability to complex environments means that materials must maintain stable performance under varying temperatures, humidity levels, air pressures, and potential corrosion. Among numerous materials, aluminum alloy forgings, with their outstanding comprehensive performance, have become the top choice for key components of flying cars.

[0003] The ability of aluminum alloy forgings to undertake this crucial task is due to the unique advantages of precision forging technology. During precision forging, the aluminum alloy matrix gradually forms a dense fibrous structure. This special microstructure, while retaining the high specific strength and high fatigue resistance inherent in aerospace-grade aluminum alloys (such as 7075-T6 and 2A14-T6), also significantly improves the overall structural integrity. High specific strength allows for weight reduction while maintaining strength, while high fatigue resistance ensures that the flying car is less prone to fatigue damage during long-term, frequent use. The improved overall integrity further enhances the structural stability and reliability, providing a solid guarantee for the safe operation of the flying car.

[0004] Taking the door sill beam of a flying car as a key component as an example, its structural design is quite complex. The sill beam cavity not only contains reinforcing components to enhance the overall structural strength and rigidity to withstand various external impacts that may be encountered during flight and driving, but also includes various other component mounting parts. These mounting parts are crucial hubs for connecting and securing other related components. However, in the actual production assembly process, the assembly of these mounting parts faces numerous challenges. Due to the long length and large quantity of materials, assembly currently relies mainly on manual labor. Manual assembly is not only time-consuming but also extremely difficult. Accurately installing long and numerous materials into designated positions within a confined space is a significant test of the worker's skills and patience. Furthermore, to improve assembly efficiency and accuracy, close cooperation among multiple people is often required to complete this task, which undoubtedly further increases labor costs and the complexity of production management. Summary of the Invention

[0005] This invention proposes a core-pulling riveting device that combines automatic assembly and positioning with manual riveting, thereby solving the problem mentioned in the background art where the narrow internal space of aluminum alloy forgings makes it difficult to install and position reinforcing parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a core-pulling riveting device, comprising: a frame, with a tooling fixture for positioning and fastening the main beam of the forging fixedly installed in the middle, and a left core rod feeding assembly and a right core rod feeding assembly, a left position detection assembly and a right position detection assembly correspondingly arranged at both ends; the left core rod feeding assembly is provided with a trolley and a base, the trolley can move left and right along the frame, and a left core rod body is installed on the base, the left core rod body is used to limit the installation of the left accessory; a riveting hole is opened on the side of the main beam of the forging, and a round hole is opened on the side of the left accessory, when the left core rod body feeds the left accessory into the interior of the main beam of the forging, the riveting hole and the round hole correspond.

[0007] Furthermore, the left-side positioning detection component is equipped with multiple detection gratings to detect whether the left accessory has been placed in the correct position.

[0008] Furthermore, a safety light curtain and a reservation button are installed on the side of the rack.

[0009] Furthermore, a magnet is installed on the side of the left core rod for magnetically securing the accessory.

[0010] Furthermore, a push plate is movably mounted on the side of the left mandrel body, and a synchronous bracket is movably mounted on the side of the left mandrel body via a round rod. The top of the synchronous bracket is fixedly connected to the push plate. A reset push spring located on the outer side of the round rod is installed between the synchronous bracket and the left mandrel body. A positioning pin is movably fitted at the end of the push plate, and a nut is threaded to the end of the positioning pin. A positioning push spring is provided between the positioning pin and the push plate. A magnet fixed to the end of the round rod can attract and tighten the left accessory side. The attraction of the magnet to the left accessory achieves fixation. The positioning pin passes through the round hole and then positions the left accessory with a pin shaft.

[0011] Furthermore, the central cross-section of the push plate is T-shaped.

[0012] Furthermore, there is a connecting rod inside the left core rod that moves up and down via a guide rod, and a limit spring is provided between the connecting rod and the nut at the top of the guide rod. A limit seat is fixedly installed at the end of the connecting rod, and a reset wedge block is fixedly installed at the top of the synchronous coupling rod. A limit wedge block is fastened to the bottom of the connecting rod by bolts. When the reset wedge block is pushed towards the limit wedge block, it can drive the limit wedge block to move upward.

[0013] Furthermore, the side shape of the limiting seat is a right-angled triangle.

[0014] Furthermore, a positioning groove is provided on the top of the forged main beam.

[0015] The present invention has the following beneficial effects:

[0016] In the field of flying car manufacturing, aluminum alloy forgings, with their superior performance, have become the core material for constructing key structural components of flying cars. Flying cars have extremely stringent requirements for structural strength, weight, and adaptability to complex environments. Aluminum alloy forgings, especially those processed by precision forging, not only possess high specific strength and high fatigue resistance but also maintain stable performance in complex and variable flight environments, providing a solid guarantee for the safe and reliable operation of flying cars. Among them, the forged main beam, as an important load-bearing component of flying cars, directly affects the structural strength and service life of the entire flying car through the assembly and fixing quality of its internal reinforcements.

[0017] To efficiently and accurately assemble and fix the internal reinforcing components of the forged main beam, this application proposes a core-pulling riveting device. In actual production, workers first place the aluminum alloy forged main beam for flying cars onto a tooling fixture. This tooling fixture has been calibrated to accurately fix the position of the forged main beam, providing a stable foundation for subsequent assembly work. Next, the feeding components on the left and right sides of the device begin to function. These feeding components can transport the attachments to designated positions inside the forged main beam according to a preset program.

[0018] After all attachments are accurately positioned, the manual core-pulling and riveting process begins. Workers use specialized tools to perform the core-pulling and riveting operation. This process ensures that the reinforcing components inside the forged main beam are securely assembled. After riveting, to ensure worker safety, the worker must manually exit the grating area. The grating area is a safety protection device that can promptly issue an alarm and stop equipment operation if a worker enters the danger zone, effectively preventing accidents. Subsequently, the worker presses the reservation button to start the robot material handling program. Following a preset path and program, the robot quickly and accurately removes the riveted forged main beam and places it in the designated storage area.

[0019] After material is picked up, the worker immediately places down a piece of aluminum alloy forging for a flying car to be assembled, and the equipment then enters the next cycle of material picking and assembly. Through this cyclical operation, the core-pulling riveting equipment achieves efficient and continuous production, greatly improving the assembly and fixing efficiency of internal reinforcements in the forged main beam, and providing strong support for the large-scale production of flying cars.

[0030] The technical solutions of the embodiments 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, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, please refer to Figure 1 , Figure 2 and Figure 7As can be seen, the frame 1 is fixedly installed in the required position. A safety light curtain 3 is installed on the side of the frame 1. The safety light curtain 3 can detect the working area of ​​the frame 1. When someone enters the area, the entire machine will stop working, greatly ensuring the safety of the workers. Furthermore, to further enhance safety, when the worker moves away from the monitored area, pressing the reservation button 19 fixed to the side of the safety light curtain 3 will cause the machine to resume operation. This manual operation ensures stable equipment movement while preventing accidental injury to workers who approach the frame 1.

[0032] In the cutting-edge field of flying car manufacturing, aluminum alloy forgings, with their outstanding performance, firmly occupy a core position in constructing key structural components for flying cars, becoming an undisputed key material. As a new type of transportation integrating aviation and automotive technologies, flying cars place almost stringent requirements on structural strength, weight, and adaptability to complex environments. They need to withstand enormous aerodynamic loads during high-speed flight while maintaining stable operation in complex weather conditions and geographical environments. This requires their structural components to be both sufficiently robust and as lightweight as possible to reduce energy consumption and improve flight efficiency. In this application, to ensure that the aluminum alloy forgings for flying cars can withstand higher loads, internal reinforcement components are riveted into them. However, in practical applications, workers found that the forged main beam 7 is long overall but has relatively small internal space, which is not conducive to positioning the reinforcing parts (i.e., the left attachment 8 mentioned in this application). Therefore, to facilitate riveting and assembly, a tooling fixture 2 is fixedly installed in the middle of the frame 1. The tooling fixture 2 includes positioning components such as positioning pins, positioning cylinders, pressure plates, and positioning baffles, ensuring that the position and angle of the forged main beam 7 can be precisely limited after placement. The specific positions of the components on the tooling fixture 2 can be adjusted according to the actual structural characteristics of the forged main beam 7. Therefore, this application does not impose excessive restrictions on the structure of the tooling fixture 2.

[0033] Based on this, in order to ensure that the left attachment 8 can be accurately and stably fed into the forged main beam 7 for riveting, combined with Figure 1 , Figure 2 and Figure 7It can be seen that the left mandrel feeding assembly 5 and the right mandrel feeding assembly 500 are symmetrically arranged on the left and right sides of the frame 1, located near both ends of the forging main beam 7. A left-side positioning detection assembly 6 and a right-side positioning detection assembly 600 are mounted on the surface of the frame 1 on one side of the left and right mandrel feeding assemblies 5 and 500, respectively. The left mandrel feeding assembly 5 and the left-side positioning detection assembly 6 are located at the left end of the forging main beam 7, while the right mandrel feeding assembly 500 and the right-side positioning detection assembly 600 are located near the right end of the forging main beam 7. The left mandrel feeding assembly 5 and the right mandrel feeding assembly 500 have identical structures, as do the left-side positioning detection assembly 6 and the right-side positioning detection assembly 600. Therefore, this application focuses on describing the left mandrel feeding assembly 5 and the left-side positioning detection assembly 6, while the right mandrel feeding assembly 500 and the right-side positioning detection assembly 600 are identical and will not be described repeatedly.

[0034] Regarding the arrangement of the left mandrel feeding assembly 5, from Figure 1 and Figure 2 As can be seen, the left mandrel feeding assembly 5 includes a trolley 501 and a base 502, which are detachably fixedly connected. The trolley 501 can move left and right via a slide rail on the frame 1, restricting the left mandrel feeding assembly 5 to horizontal movement only. For the drive mechanism, a servo motor with a lead screw can be used, including but not limited to pneumatic / hydraulic cylinder transmission, as long as the trolley 501 can move left and right in a directional and fixed-distance manner. The left mandrel body 9 is mounted on the base 502. For assemblies of different workpiece types, the base 502 and the left mandrel body 9 can be directly detached from the trolley 501 and installed onto the corresponding base 502 and left mandrel body 9. The left core rod 9 provides a space for limiting the installation of the left accessory 8. In this embodiment, when fixing the left accessory 8, multiple magnets 15 can be installed on the side of the left core rod 9. The magnets 15 attract the left accessory 8, so that the left accessory 8 is always in close contact with the side of the left core rod 9, ensuring that the left accessory 8 can remain relatively stable after placement.

[0035] Regarding the arrangement of the left-side positioning detection component 6, multiple detection gratings 601 are set on the left-side positioning detection component 6. The detection gratings 601 can detect the corresponding parts on the left accessory 8. When the left accessory 8 is placed on the left mandrel body 9, the multiple detection gratings 601 detect each component on the left accessory 8. If a signal is detected, the signal will be transmitted to the touch screen and control unit 4 fixed on the frame 1 in the form of an electrical signal. According to the control of the touch screen and control unit 4, the accurately positioned left accessory 8 can be driven into the interior of the forging main beam 7.

[0036] like Figure 2 and Figure 7As shown, the forged main beam 7 has a riveting hole 701 on its side, and correspondingly, the left accessory 8 has a round hole on its side. When the left mandrel 9 inserts the left accessory 8 into the forged main beam 7, the riveting hole 701 and the round hole align, and the left accessory 8 also adheres to the inner side of the forged main beam 7. Then, the riveting assembly is manually positioned between the riveting hole 701 and the round hole, ultimately achieving the riveting fixation between the forged main beam 7 and the left accessory 8.

[0037] In practical application of this embodiment: The worker places the forged main beam 7 on the tooling fixture 2 and clamps it in place. Then, the worker places the left accessory 8 on the left mandrel body 9 and uses the left mandrel feeding assembly 5 to feed the left accessory 8 into the detection area of ​​the left positioning detection assembly 6. The position of the left accessory 8 is detected according to the detection grating 601. When the positioning is accurate, the left mandrel feeding assembly 5 can feed the left accessory 8 into the forged main beam 7 and achieve alignment between the riveting hole 701 and the circular hole on the left accessory 8; similarly, if the positioning is inaccurate, the left accessory 8 will not be pushed into the forged main beam 7. The right mandrel feeding assembly 500 on the right side operates in the same manner.

[0038] Once the riveting hole 701 aligns with the circular hole on the left accessory 8, the worker performs core-pulling riveting using the riveting equipment. After completion, the worker pushes out the detection area of ​​the safety light curtain 3 and presses the reservation button 19. Finally, the left mandrel feeding assembly 5 and the right mandrel feeding assembly 500 on both sides are pulled out, and the forged main beam 7 is removed and transported to the next process by a robot. By repeating the above steps, continuous riveting and fixing of the workpiece can be achieved.

[0039] Example 2 is a further improvement on Example 1. Please refer to Example 1. Figures 3-6 It can be seen that multiple sets of limiting and detection components are installed on the side of the left mandrel body 9. Specifically, the limiting and detection components include: a push plate 16 movably installed on the side of the left mandrel body 9, the central cross-section of the push plate 16 being "T"-shaped. There are two synchronous couplings 18 movably installed on the side of the left mandrel body 9 via round rods, both of which are movably installed on the left mandrel body 9. The top of the synchronous coupling 18 is fixedly connected to the push plate 16. When the synchronous coupling 18 moves left and right along the side of the left mandrel body 9 using the round rods, it can drive the push plate 16 to reciprocate left and right along the side of the left mandrel body 9. Figure 6As can be seen, a reset spring 180 located on the outer side of the round rod is installed between the synchronous coupling 18 and the left core rod 9. The spring force of the reset spring 180 causes the synchronous coupling 18 to always tend to move away from the left core rod 9. Furthermore, a positioning pin 17 is movably fitted at the end of the push plate 16, and a nut is threaded onto the end of the positioning pin 17. The nut restricts the position of the positioning pin 17, preventing it from disengaging from the push plate 16. A positioning spring 170 is provided between the positioning pin 17 and the push plate 16. The spring force of the positioning spring 170 causes the positioning pin 17 to always tend to move away from the left core rod 9. During this process, when the left accessory 8 is placed on the side of the left core rod 9, the magnet 15 fixed to the end of the round rod can attract and secure the side of the left accessory 8. During this process, magnet 15 attracts and pulls synchronous coupling 18 towards left accessory 8. When synchronous coupling 18 drives push plate 16 towards left accessory 8, positioning pin 17 can be pushed out from the round hole of left accessory 8. Then, the attraction of magnet 15 to left accessory 8 is used to fix it. Positioning pin 17 passes through the round hole and then pin-positions left accessory 8, further ensuring the positioning accuracy of left accessory 8.

[0040] Furthermore, each set of limiting and detection components corresponds to the detection grating 601 on the left-side positioning detection assembly 6. Therefore, when the positioning pin 17 extends from the round hole, the detection grating 601 can detect the positioning pin 17. If each positioning pin 17 extends from the round hole, the detection grating 601 can detect all the positioning pins 17. Conversely, if the left accessory 8 is not installed correctly, the positioning pin 17 will not push out of the round hole. In this case, the positioning pin 17 abuts against the side of the left accessory 8 and compresses the positioning spring 170, preventing all the positioning pins 17 from extending from the round hole. Finally, if the detection grating 601 cannot detect the position of all the positioning pins 17, it indicates that the left accessory 8 is not accurately positioned, and the left accessory 8 will not be pushed into the forging main beam 7 for subsequent riveting work.

[0041] Based on this, combined Figures 3-6It can be seen that there is a connecting rod 11 on the inner side of the left mandrel 9, which is limited in its vertical movement by a guide rod. A limit spring 13 is provided between the connecting rod 11 and the nut at the top of the guide rod. The spring force of the limit spring 13 pushes the connecting rod 11 so that it always tends to move downward. Moreover, a limit seat 10 is fixedly installed at the end of the connecting rod 11. When the connecting rod 11 moves upward by the guide rod and drives the limit seat 10 upward, the limit seat 10 can be pushed upward from the top of the left mandrel 9; conversely, when the connecting rod 11 moves downward, the limit seat 10 moves downward and its top is lower than the side of the left mandrel 9. The side shape of the limit seat 10 is a right-angled triangle. When the left mandrel 9 pushes the limit seat 10 forward, the inclined surface of the limit seat 10 is blocked and tends to move downward. Based on this, a reset wedge block 14 is fixedly installed at the top of the round rod of the synchronous connecting frame 18. Correspondingly, a limit wedge block 12 is installed at the bottom of the connecting rod 11 by bolts. The limit wedge block 12 and the reset wedge block 14 are wedge blocks that cooperate with each other. When the reset wedge block 14 pushes towards the limit wedge block 12, it can drive the limit wedge block 12 to move upward.

[0042] In practical application, after the worker places the left accessory 8 on the left core rod 9, the magnet 15 uses magnetic force to attract the left accessory 8 and drives the synchronous frame 18 to move closer to the left accessory 8. The synchronous frame 18 pushes the push plate 16 to move towards the left accessory 8. If the positioning is accurate, the positioning pin 17 can be pushed out from the round hole of the left accessory 8.

[0043] The left mandrel feeding assembly 5 moves the left mandrel body 9 to below the left-side positioning detection assembly 6. The detection grating 601 performs positioning detection on the protruding positioning pins 17. When all positioning pins 17 are detected, it indicates that the left accessory 8 is accurately positioned. Then, the left mandrel feeding assembly 5 feeds the left mandrel body 9 into the forging main beam 7. When the synchronous connecting frame 18 pushes towards the left accessory 8, the cooperation between the reset wedge block 14 and the limiting wedge block 12 causes the connecting rod 11 to drive the limiting seat 10 to move upward, and the limiting seat 10 extends out from the left mandrel body 9. Before the left mandrel body 9 is inserted into the forging main beam 7, the end of the forging main beam 7 abuts against the side of the left mandrel body 9, forcing it to press outward, thereby facilitating the insertion of the left mandrel body 9 into the forging main beam 7. Subsequently, as the left mandrel 9 is further inserted into the forged main beam 7, upon reaching the assembly position, the limiting seat 10 extends from the positioning groove 700 opened at the top of the forged main beam 7, and the positioning pin 17 extends from the round hole and riveting hole 701 on the left accessory 8. At this point, the left mandrel 9 delivers the left accessory 8 to the designated position inside the forged main beam 7.

[0044] Workers then use a core-pulling riveting device to connect the left accessory 8 and the forged main beam 7. Specifically, the rivet abuts against the top of the positioning pin 17, causing the positioning pin 17 to further compress the positioning push spring 170. After the positioning push spring 170 reaches its compression limit, it pushes the push plate 16 away from the left accessory 8 until the reset wedge block 14 at that location disengages from the limiting wedge block 12. After the rivet is riveted, the magnetic force of the left accessory 8 attracted by the magnet 15 causes the synchronous coupling 18 to push the positioning pin 17 further towards the rivet. If the rivet is not properly tightened at this time, it will be pushed out of the riveting hole 701 by the positioning pin 17, thus using the positioning pin 17 to check whether the rivet is properly tightened.

[0045] After all rivets are properly installed, the locating pin 17 pushes the synchronous coupling 18 and moves the reset wedge block 14 away from the limiting wedge block 12. At this time, all reset wedge blocks 14 are separated from the limiting wedge block 12. The connecting rod 11 moves downward under the force of the limiting spring 13, and the limiting seat 10 moves down along the locating groove 700, ensuring that the left mandrel body 9 is not obstructed when it is pulled out. Similarly, if there is a missing rivet hole 701 or the rivet is not tightened properly, at least one set of reset wedge blocks 14 will abut against the limiting wedge block 12, forcing the connecting rod 11 to always keep the limiting seat 10 pushing upward. At this time, when the left accessory 8 is retracted from the forging main beam 7 again, the limiting seat 10 will abut against the locating groove 700, thereby restricting the recovery of the left mandrel feeding assembly 5. When the recovery resistance of the left mandrel feeding assembly 5 reaches the set threshold, the touch screen and control unit 4 will stop the movement of the left mandrel feeding assembly 5 and issue an alarm to prevent the left mandrel feeding assembly 5 from damaging the forging main beam 7, and to warn the operator that there is an assembly defect in the rivet hole 701, which needs to be inspected.
