[0034] Embodiment 1: A kind of arc extinguishing cover riveting device, including device support frame 1, device support frame 1 bottom four legs are welded with device fixed bottom frame 2 between four legs, and bottom bracket cushion 3 is respectively installed below four legs, device support frame 1 top is bolted with riveting workbench 4, riveting workbench 4 is welded with riveting protective cover 5, riveting protective cover 5 is transversely installed with reinforcing plate 6, riveting cylinder 7 is connected on the outer surface of reinforcing plate 6. Riveting cylinder 7 is slidably connected with riveting piston rod 8 in the inside, and riveting punch 9 is arranged at the bottom rod of riveting piston rod 8. Riveting punch 9 is provided with riveting die 10 at punch head, and riveting die 10 is in horizontal state, and riveting limiting block 11 is connected below riveting die 10.

[0035] Riveting pressure sensor 12 is installed on one side of riveting limiting block 11, and riveting buffer pad 13 is arranged at the left upper side of riveting pressure sensor 12. Riveting feeding cylinder 14 is installed above riveting workbench 4, feeding telescopic rod 15 is embedded in the inside of riveting feeding cylinder 14, and riveting feeding push block 16 is connected at the top end of feeding telescopic rod 15. Feeding table 17 is slidably connected above riveting pressure sensor 12, and riveting feeding push block 16 is connected at the tail of feeding table 17. Position sensor 18 is connected on one side of reinforcing plate 6, and arc extinguishing cover discharging cylinder 19 is installed above riveting feeding cylinder 14. Telescopic piston rod cylinder 20 is slidably connected in the inside of arc extinguishing cover discharging cylinder 19, arc top head 21 is arranged at the front end of telescopic piston rod cylinder 20, and arc extinguishing cover discharging storage tank 22 is installed below arc top head 21. Protective cover opening and closing door 23 is hingedly installed on the door frame of riveting protective cover 5.

[0036] Specific working principle: the operator opens the protective cover opening and closing door 23, and places the to-be-riveted arc-extinguishing cover on the feeding table 17, and then closes the protective cover opening and closing door 23, and prepares for riveting work. The riveting feeding cylinder 14 is started, the feeding telescopic rod 15 in the interior thereof is extended forward, and pushes the riveting feeding push block 16 connected therewith. Since the tail part of the feeding table 17 is connected with the riveting feeding push block 16, the feeding table 17 is pushed by the riveting feeding push block 16 and slides forward along the predetermined track, accurately delivering the arc-extinguishing cover to the riveting position. The position sensor 18 monitors the position of the feeding table 17 in real time, and sends a signal when the feeding table 17 reaches the specified riveting position, so that the riveting feeding cylinder 14 stops working, and the feeding process is completed.

[0037] When the feeding table 17 reaches the riveting position, the riveting cylinder 7 starts to work. The riveting piston rod 8 in the interior of the riveting cylinder 7 slides downward under the action of the gas pressure, and drives the riveting punch 9 installed at the bottom rod thereof to move downward. When the riveting punch 9 moves downward, the riveting die 10 at the punch part thereof acts on the riveting part of the arc-extinguishing cover. Since the riveting die 10 is in a transverse state, the arc-extinguishing cover can be riveted in a specific direction. In the riveting process, the riveting limiting block 11 plays a role in limiting the riveting depth, preventing excessive riveting. At the same time, the riveting buffer pad 13 can buffer the impact force generated in the riveting process, reducing the damage to the equipment and the arc-extinguishing cover.

[0038] The riveting pressure sensor 12 monitors the pressure change in the riveting process in real time.

[0041] The riveting protective cover 5 can prevent the operator from being accidentally injured during the riveting process, and also avoid the debris generated during the riveting process from splashing out, ensuring the safety of the working environment. The arc extinguishing cover riveting device realizes the automation of arc extinguishing cover riveting through the cooperation of various components, and has multiple protection and monitoring functions, which can efficiently and stably complete the riveting work of the arc extinguishing cover.

[0042] In embodiment 2, the device support frame 1 is placed stably at a designated position in the workshop, and the welding structure of the device fixed bottom frame 2 ensures the stability of the whole device. The structure of the device fixed bottom frame 2 enables the whole device to withstand a large impact force and vibration, providing a solid foundation for subsequent riveting work. The bottom bracket cushion 3 is installed under the four legs of the device support frame 1, further enhancing the stability and shock absorption effect of the device. The bottom bracket cushion 3 can effectively reduce the vibration generated during equipment operation, which affects the ground and the surrounding environment, and also reduces the wear and tear of the device components.

[0043] The riveting workbench 4 is fixed to the top of the device support frame 1 by bolts, ensuring the tightness and reliability of the connection. The bolt connection method is convenient for later maintenance and disassembly, facilitating the cleaning and maintenance of the workbench. The riveting protective cover 5 is welded to the riveting workbench 4 to ensure the effectiveness of its protective function. The riveting protective cover 5 can prevent the operator from being injured by flying debris and sparks during the riveting process, ensuring the safety of the workers.

[0044] The reinforcing plate 6, riveting cylinder 7, riveting feeding cylinder 14, arc extinguishing cover discharge cylinder 19 and other components are installed in sequence, and the electrical and pneumatic systems are connected according to the structural requirements. Turn on the power and gas source, and conduct a comprehensive inspection and debugging of the device. First, test the sensitivity and accuracy of the position sensor 18 and the riveting pressure sensor 12. Through the simulation of the feeding and riveting process, ensure that the position sensor 18 can accurately detect the position of the feeding table 17, and the riveting pressure sensor 12 can real-time feedback the change of the riveting pressure.

[0045] Adjust the stroke and speed of the riveting cylinder 7, riveting feeding cylinder 14 and arc extinguishing cover discharge cylinder 19. According to the riveting requirements of different specifications of arc extinguishing cover, adjust the motion parameters of the cylinder to ensure the smoothness and efficiency of the feeding, riveting and discharging process.

[0046] Fine-tune the riveting die 10 to ensure its accurate matching with the riveting position of the arc extinguishing cover. Through multiple trial riveting, check the riveting quality such as riveting depth, riveting strength, etc., and make further adjustment and optimization according to the actual situation.

[0047] The operator opens the protective cover opening and closing door 23, and places the to-be-riveted arc-extinguishing cover on the feeding table 17. The structure of the feeding table 17 enables the arc-extinguishing cover to be stably placed, facilitating subsequent feeding and riveting operations.

[0048] Close the protective cover opening and closing door 23, start the control system of the device, and make the device enter the standby state.

[0049] The control system issues a feeding instruction, and the riveting feeding cylinder 14 starts to work. The feeding telescopic rod 15 extends forward, pushing the riveting feeding push block 16 to move, thereby driving the feeding table 17 to slide to the riveting station.

[0050] The position sensor 18 monitors the position of the feeding table 17 in real time. When the feeding table 17 reaches the specified riveting position, the position sensor 18 sends a signal to the control system, and the riveting feeding cylinder 14 stops working, and the feeding is completed.

[0051] After receiving the feeding completion signal, the control system starts the riveting cylinder 7. The riveting piston rod 8 slides downward under the action of gas pressure, driving the riveting punch 9 and the riveting die 10 to perform transverse riveting on the arc-extinguishing cover.

[0052] The riveting limiting block 11 limits the riveting depth, ensuring consistent riveting depth each time and stability of riveting quality. The riveting buffer pad 13 buffers the impact force generated during riveting, reducing damage to the equipment and the arc-extinguishing cover.

[0053] The riveting pressure sensor 12 monitors the riveting pressure in real time and feeds back the data to the control system. If the riveting pressure exceeds or is lower than the preset range, the control system will automatically adjust the gas pressure of the riveting cylinder 7 or stop the riveting operation to ensure the riveting quality.

[0054] After riveting is completed, the control system starts the arc-extinguishing cover ejection cylinder 19. The telescopic piston rod cylinder 20 extends forward, driving the circular arc top head 21 to push the riveted arc-extinguishing cover out of the feeding table 17, and the arc-extinguishing cover falls into the arc-extinguishing cover ejection storage box 22 below.

[0055] After ejection is completed, the piston rods of the riveting feeding cylinder 14 and the arc-extinguishing cover ejection cylinder 19 are retracted, respectively, the feeding table 17 returns to the initial position, and is ready for the next feeding,

[0056] The working process of the arc-extinguishing cover riveting device is as follows: checking whether the welding between the device fixed bottom frame 2 and the device support frame 1 is firm, whether the bottom frame buffer pad 3 is installed perfectly and is not damaged, and ensuring the overall stability of the device. Checking whether the bolt connection between the riveting workbench 4 and the device support frame 1 is tightened. Checking whether the riveting protective cover 5 and the protective cover opening and closing door 23 can be normally used without damage and jamming.

[0057] Turn on the power supply, start the control system, and make the riveting cylinder 7, riveting feeding cylinder 14, arc extinguishing cover discharging cylinder 19 and other pneumatic components in standby state. Check whether the position sensor 18 and riveting pressure sensor 12 are working normally and can accurately feedback data. Open the protective cover opening and closing door 23, and place the arc extinguishing cover to be riveted on the feeding table 17 at a suitable position. Close the protective cover opening and closing door 23 to ensure safety.

[0058] The control system sends a command, and the riveting feeding cylinder 14 starts working. The feeding telescopic rod 15 extends forward. The feeding telescopic rod 15 pushes the riveting feeding push block 16 connected thereto to move forward. Since the tail of the feeding table 17 is connected with the riveting feeding push block 16, the feeding table 17 is pushed by the riveting feeding push block 16 to slide along the preset track to the riveting position. The position sensor 18 monitors the position of the feeding table 17 in real time during the movement of the feeding table 17.

[0059] When the feeding table 17 reaches the specified riveting position, the position sensor 18 sends a signal to the control system, and the control system stops the work of the riveting feeding cylinder 14, and the feeding is completed.

[0060] After receiving the feeding completion signal, the control system starts the riveting cylinder 7. The riveting piston rod 8 in the riveting cylinder 7 slides downward under the action of gas pressure. The riveting piston rod 8 drives the riveting punch 9 to move downward. The riveting die 10 at the punch head of the riveting punch 9 acts on the riveting position of the arc extinguishing cover to perform horizontal riveting operation.

[0061] The riveting limiting block 11 limits the riveting depth to prevent over-riveting. The riveting buffer pad 13 buffers the impact force generated during riveting to protect the equipment and workpiece. The riveting pressure sensor 12 monitors the pressure change in the riveting process in real time and feeds back the data to the control system.

[0062] If the riveting pressure exceeds or is lower than the preset range, the control system adjusts the gas pressure of the riveting cylinder 7 or stops the riveting operation to ensure the riveting quality. After riveting is completed, the control system starts the arc extinguishing cover discharging cylinder 19. The telescopic piston rod cylinder 20 in the arc extinguishing cover discharging cylinder 19 extends forward.

[0063] The arc top head 21 at the front end of the telescopic piston rod cylinder 20 moves forward to push the riveted arc extinguishing cover out of the feeding table 17. The arc extinguishing cover falls into the arc extinguishing cover discharging storage box 22 below. After discharging is completed, the piston rods of the riveting feeding cylinder 14 and the arc extinguishing cover discharging cylinder 19 are retracted, respectively.
