Description

Technical Field

[0001] This application belongs to the field of aerospace rivet production technology, and in particular relates to an aerospace-specific rivet assembly device. Background Art

[0002] A rivet is a nail-shaped object used to connect two parts with through holes and a cap at one end. In riveting, the parts are joined by their own deformation or interference fit. There are many types of rivets, and they come in various forms. Commonly used types include R-type rivets, fan rivets, blind rivets, tree rivets, round head rivets, flat head rivets, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, and hollow rivets. These typically join the parts by their own deformation.

[0003] Currently, due to the high precision requirements of aerospace-grade blind rivets, the diameter of the tail end of the blind rivet must differ from the diameter of the rivet gun head's connecting hole by less than 1mm. Existing technology uses bolt tightening for fixing, requiring manual adjustment of the bolt clamping mechanism to fix the rivet component during the processing and assembly of each aerospace rivet. This not only results in low efficiency but also poor fixing effect and easy movement of the rivet during processing, leading to large processing errors. In addition, after each rivet is processed, workers need to unload the finished product, which is quite inconvenient.

[0004] To address this issue, we propose a specialized aerospace rivet assembly device. Utility Model Content

[0005] The purpose of this application is to solve the problems of poor rivet fixing effect and inability to automatically unload in the prior art, and to propose an aerospace-specific rivet assembly device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A space-specific rivet assembly device includes an assembly machine. A controller is located below the assembly machine. A baffle is fixedly connected to the left side of the assembly machine. A connecting pipe is fixedly connected to the back of the baffle. Two hydraulic cylinders are fixedly connected to the bottom of the baffle. The telescopic ends of the two hydraulic cylinders are jointly fixedly connected to a clamping block. Two grooves are formed on the bottom surface of the clamping block. Two first force springs are fixedly connected to the inner top wall of the clamping block. A pressure sensor is fixedly connected to the bottom end of each first force spring. Two sets of second force springs are fixedly connected to the inner top wall of the clamping block. A transmission block is fixedly connected to the bottom end of each set of second force springs. A support plate is fixedly connected to the left side of the assembly machine. A rectangular plate is fixedly connected to the back of the support plate. A telescopic rod is fixedly connected to the front of the rectangular plate. A push plate is fixedly connected to the telescopic end of the telescopic rod. The bottom surface of the push plate is in contact with the upper surface of the support plate. The controller is electrically connected to the pressure sensor, the hydraulic cylinder, and the telescopic rod via wires.

[0008] Preferably, the bottom surface of the support plate is fixedly connected to two support legs, and the bottom surface of each support leg is fixedly connected to two base plates.

[0009] Preferably, a long plate is fixedly connected to one side of the two supporting legs that are close to each other, and the upper surface of the long plate is fixedly connected to the bottom surface of the supporting plate.

[0010] Preferably, a control box is fixedly connected to the left side of the long plate, and the inner wall of the control box is fixedly connected to the right side of the controller.

[0011] Preferably, the control box has a hinged door on its left side, and a pull handle is fixedly connected to the left side of the door.

[0012] Preferably, one of the support legs has a slot on its front side, and a locking block is engaged inside the slot. A collection box is provided below the support plate, and the back of the collection box is fixedly connected to the end of the locking block away from the controller.

[0013] In summary, the technical effects and advantages of this application are as follows:

[0014] By employing a hydraulic cylinder, a clamping block, and a controller, the hydraulic cylinder and clamping block are moved downwards to secure the rivets to be processed. This convenient and quick fixing method ensures efficient rivet processing and effectively avoids the need for manual tightening of bolts when fastening rivets. Furthermore, the system utilizes a pressure sensor, a groove, a first force spring, a second force spring, a transmission block, a support plate, a telescopic rod, and a push plate. The clamping block presses against the rivets, causing the transmission block to be pressurized towards the pressure sensor. This pressure sensor transmits an electrical signal to the controller, which keeps the telescopic rod in a ready state. When the pressure on the sensor dissipates, the telescopic rod pushes the push plate to move the processed rivets into the collection device, achieving automatic unloading. This effectively avoids the inconvenience of manual unloading during operation. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4A special aerospace rivet assembly device includes an assembly machine 1, a controller 9 located below the assembly machine 1, a baffle 2 fixedly connected to the left side of the assembly machine 1, a connecting pipe 14 fixedly connected to the back of the baffle 2, two hydraulic cylinders 13 fixedly connected to the bottom surface of the baffle 2, and a pressing block 15 fixedly connected to the telescopic ends of the two hydraulic cylinders 13. Two grooves 20 are formed on the bottom surface of the pressing block 15, and two first force springs 21 are fixedly connected to the inner top wall of the pressing block 15. A pressure spring is fixedly connected to the bottom end of each first force spring 21. Sensor 22 and pressing block 15 have two sets of second force springs 24 fixedly connected to their inner top walls. The bottom of each set of second force springs 24 is fixedly connected to a transmission block 23. A support plate 7 is fixedly connected to the left side of the assembly machine 1. Two support legs 8 are fixedly connected to the bottom surface of the support plate 7. Two base plates 6 are fixedly connected to the bottom surface of each support leg 8. By setting the support legs 8 and base plates 6, the support legs 8 can provide support for the device, and the base plates 6 can increase the contact area with the ground, thereby making the device stand more stably.

[0022] A rectangular plate 18 is fixedly connected to the back of the support plate 7. A long plate 12 is fixedly connected to one side of the two support legs 8 that are close to each other. The upper surface of the long plate 12 is fixedly connected to the bottom surface of the support plate 7. By setting the long plate 12, the device can be provided with a force-bearing position through the long plate 12, which plays a good auxiliary role.

[0023] A telescopic rod 16 is fixedly connected to the front of the rectangular plate 18, and a push plate 17 is fixedly connected to the telescopic end of the telescopic rod 16. A control box 3 is fixedly connected to the left side of the long plate 12, and the inner wall of the control box 3 is fixedly connected to the right side of the controller 9. By setting up the control box 3, the controller 9 can be protected, ensuring that no dust enters the interior of the controller 9 when it is working.

[0024] The bottom surface of the push plate 17 is in contact with the upper surface of the support plate 7. The left side of the control box 3 is movably hinged with a movable door 4. The left side of the movable door 4 is fixedly connected with a pull handle 5. By setting the pull handle 5 and the movable door 4, the movable door 4 can be opened by pulling the pull handle 5, thereby facilitating the application of pulling force to the movable door 4.

[0025] The controller 9 is electrically connected to the pressure sensor 22, the hydraulic cylinder 13, and the telescopic rod 16 via wires. One of the support legs 8 has a slot 19 on its front side, and a locking block 10 is engaged inside the slot 19. A collection box 11 is provided below the support plate 7. The back of the collection box 11 is fixedly connected to the end of the locking block 10 away from the controller 9. By setting up the slot 19, the locking block 10, and the collection box 11, the collection box 11 can be fixed by the locking block 10 engaging inside the slot 19, thus achieving a good fixing effect.

[0026] The working principle of this utility model is as follows: In use, first connect the controller 9, telescopic rod 16, hydraulic cylinder 13, and pressure sensor 22 to the power supply. Once the power is connected, the device can be used normally. When this device is needed, simply place the rivet to be processed on the surface of the support plate 7, then control the controller 9 to operate the hydraulic cylinder 13. The hydraulic cylinder 13 pushes the two clamping blocks 15 downwards to fix the rivet to be processed. This effectively avoids the inconvenience of repeatedly tightening bolts to achieve the purpose of tightening and loosening the rivet. Furthermore, when the clamping block 15 moves downwards, the transmission block 23 inside the clamping block 15 will first contact the rivet to be processed. When the transmission block 23 contacts the rivet... When the rivet comes into contact, it will be squeezed into the groove 20, thereby the transmission block 23 will come into contact with the pressure sensor 22. Under the action of the first force spring 21, the pressure sensor 22 can always be in contact with the upper surface of the transmission block 23, and ensure that the force on the pressure sensor 22 is not too strong. After the pressure sensor 22 is subjected to pressure, it will transmit a signal to the controller 9. The controller 9 will then control the telescopic rod 16 to be in a standby state. When the rivet is finished, the hydraulic cylinder 13 retracts, the pressure at the sensing end of the pressure sensor 22 disappears, and the controller 9 will control the telescopic rod 16 to push the push plate 17 to move, pushing the finished rivet into the collection box 11. This effectively avoids the problem of manual unloading when the device is in use.
