[0002] The rack support, also known as the automotive steering rack support, is a key automotive component. In the manufacturing process of the rack support, the support and the shim need to be riveted together, and the riveting process is also a key step to ensure its structural strength and assembly accuracy. However, in the traditional rack support riveting process, the loading and unloading operations need to be carried out separately. The loading can only be carried out after the unloading is completed. This method greatly reduces the working speed of rack support riveting. Therefore, this utility model provides a riveting device for rack support processing. Utility Model Content

[0003] The purpose of this invention is to provide a riveting device for processing rack support seats, so as to solve the problems mentioned in the background art.

[0005] In a preferred embodiment, the loading and unloading assembly includes a sliding frame, a guide post on the side of the sliding frame facing the loading frame, one end of the loading frame being slidably connected to the outside of the guide post, a hydraulic inclined rod being rotatably connected to one side of the sliding frame, and the other end of the hydraulic inclined rod being rotatably connected to the top of the loading frame.

[0006] In a preferred embodiment, the other end of the sliding frame is fixedly connected to a feeding frame, and both the feeding frame and the feeding frame are provided with clamping components at their ends. The feeding frame is a "Z"-shaped structure with two right angles.

[0007] In a preferred embodiment, the clamping member includes an electric push rod fixedly connected to each material rack. Connecting plates are rotatably connected to both sides of the telescopic end of the electric push rod. Clamping plates are rotatably connected to the opposite surfaces of the two connecting plates. A rotating shaft is fixedly connected to the bottom of each clamping plate. The other ends of the two clamping plates are rotatably connected to the outside of the rotating shaft.

[0008] In a preferred embodiment, a pre-pressing part is provided above the clamping member of the feeding rack, and the bottom shape of the pre-pressing part is the same as the top shape of the rack support.

[0009] In a preferred embodiment, a feeding ramp is fixedly connected to one side of the riveting table, and the feeding rack is located above the feeding ramp.

[0017] Please see Figures 1-4This utility model provides a riveting device for processing rack support seats, including an equipment box 1. A riveting table 2 is fixedly connected to the top of the equipment box 1. A hydraulic cylinder 6 is fixedly connected to the top of the riveting table 2. A riveting column 202 is fixedly connected to the top of the inner cavity of the riveting table 2, located on the telescopic end of the hydraulic cylinder 6. A riveting groove is provided at the bottom of the inner cavity of the riveting table 2, directly below the riveting column 202. A translation component 5 is fixedly connected to one side of the equipment box 1. A loading and unloading component 4 is slidably connected to the top of the translation component 5. The loading and unloading component 4 includes a loading rack 403 near one end of the material preparation rack 3. The loading and unloading component 4 includes a sliding frame. A guide column 401 is provided on the side of the sliding frame facing the loading rack 403. One end of the loading rack 403 is slidably connected to the outside of the guide column 401. A hydraulic inclined rod 402 is rotatably connected to one side of the sliding frame. The other end of the hydraulic inclined rod 402 is connected to the top of the loading rack 403. The sliding frame is rotatably connected to the other end of the sliding frame, and the unloading frame 404 is fixedly connected to the other end of the unloading frame 404 and the loading frame 403 are both equipped with clamping parts. The loading frame 403 is a "Z" shaped structure with two right angles. The clamping parts include electric push rods 405 fixedly connected to each frame. Connecting plates 406 are rotatably connected to both sides of the telescopic end of the electric push rod 405. Clamping plates 407 are rotatably connected to the opposite surfaces of the two connecting plates 406. A rotating shaft 408 is fixedly connected to the bottom of each clamping plate 407. The other ends of the two clamping plates 407 are rotatably connected to the outside of the rotating shaft 408. A pre-pressing part 409 is provided above the clamping parts of the loading frame 403. The bottom shape of the pre-pressing part 409 is the same as the top shape of the rack support. An unloading inclined plate 201 is fixedly connected to one side of the riveting table 2. The unloading frame 404 is located above the unloading inclined plate 201. It should be noted that: the translation component 5 includes a fixed frame, and the inside of the fixed frame is rotatably connected to a transmission screw. One end of the fixed frame is fixedly connected to a drive motor (an existing forward and reverse motor) connected to the transmission screw. The bottom end of the sliding frame is threadedly connected to the outside of the transmission screw inside the translation component 5. When the translation component 5 is activated, the internal drive motor drives the transmission screw to rotate, causing the sliding frame outside the transmission screw to perform horizontal transmission, which in turn drives the loading and unloading component 4 at its top to move horizontally, bringing the loading rack 403 closer to the preparation rack 3. At this time, the clamping parts at the end of the loading rack 403 start to work, the electric push rod 405 retracts, and the connecting plates 406 rotatably connected to both sides of its telescopic end move accordingly. Since clamping plates 407 are rotatably connected to the opposite surfaces of the two connecting plates 406, and the bottom of each clamping plate 407 is fixedly connected to a rotating shaft 408, and the other ends of the two clamping plates 407 are rotatably connected to the outside of the rotating shaft 408, the movement of the connecting plates 406 will cause the clamping plates 407 to rotate around the rotating shaft 408, causing the two clamping plates 407 to open. When the loading rack 403 moves to a suitable position above the placement table of the preparation rack 3, the electric push rod 405 extends and pushes the connecting plate 406 to move in the opposite direction, thereby closing the two clamping plates 407 and clamping the rack support seat to be processed. Subsequently, the translation component 5 drives the loading and unloading component 4 to continue moving, causing the loading rack 403 to move above the riveting table 2. At the same time, one end of the loading rack 403 is slidably connected to the outside of the guide column 401 of the sliding frame, and the hydraulic inclined rod 402 rotatably connected to one side of the sliding frame starts to work. The hydraulic inclined rod 402 extends and pushes the loading rack 403 downward along the guide column 401, placing the rack support seat in the riveting groove at the bottom of the inner cavity of the riveting table 2, directly below the riveting column 202. During the downward movement of the feeding rack 403, the pre-pressing part 409 above its clamping part will first contact the rack support seat. Since the bottom shape of the pre-pressing part 409 is the same as the top shape of the rack support seat, the pre-pressing part 409 can pre-press the rack support seat so that it reaches a certain pre-tight state before entering the riveting process. After the rack support seat is accurately placed in the riveting groove, the telescopic end of the hydraulic cylinder 6 moves down, which in turn drives the top plate of the riveting table 2 to move down, so that the riveting column 202 at the top of the inner cavity of the riveting table 2 moves down to perform riveting operation on the rack support seat, so that it achieves the required structural strength and assembly accuracy. After riveting is completed, the clamping part at the end of the unloading rack 404 starts to work. Its working principle is the same as that of the clamping part of the loading rack 403. The electric push rod 405 retracts to open the clamping plate 407. Then the translation component 5 drives the loading and unloading component 4 to move, so that the unloading rack 404 moves above the riveting table 2. Then the electric push rod 405 extends to close the clamping plate 407 and clamp the rack support seat that has been riveted. Afterwards, the translation component 5 drives the loading and unloading component 4 to continue moving, so that the unloading rack 404 is located above the unloading inclined plate 201 fixedly connected to one side of the riveting table 2. The hydraulic inclined rod 402 retracts, pulling the loading rack 403 to move upward along the guide column 401 (at this time, the loading rack 403 does not perform clamping operation). At the same time, under the action of gravity, the unloading rack 404 places the riveted rack support on the unloading inclined plate 201. The rack support slides down the unloading inclined plate 201 to the designated collection position, completing the unloading process.

[0018] Through the design of the loading and unloading assembly 4, while the unloading rack 404 is performing the unloading operation, the loading rack 403 can simultaneously perform the loading preparation work, realizing the synchronous operation of loading and unloading. This breaks the limitation that loading and unloading must be carried out separately in the traditional riveting operation, and loading can only be carried out after unloading is completed. This greatly shortens the processing cycle of each rack support seat and improves the overall production efficiency. The pre-pressing part 409 above the clamping part of the feeding rack 403 can pre-press the rack support seat during the feeding process. The bottom shape of the pre-pressing part 409 is the same as the top shape of the rack support seat, which can make the rack support seat reach a certain pre-tight state before entering the riveting process. This helps to reduce deformation and displacement during the riveting process, ensure that the structural strength and assembly accuracy after riveting meet the design requirements, and improve the overall quality of the product.

[0019] In this embodiment, a material preparation rack 3 is provided on one side of the equipment box 1. A rotary motor 301 is fixedly connected to the bottom of the material preparation rack 3. A rotating plate 302 is fixedly connected to the output shaft of the rotary motor 301. Placement platforms are provided on the top of both ends of the rotating plate 302. When the rotary motor 301 at the bottom of the material preparation rack 3 starts to work, its output shaft drives the rotating plate 302 to rotate. Placement platforms are provided on the top of both ends of the rotating plate 302. The operator places the rack support seat to be processed on the two placement platforms respectively. When the rack support seat on one placement platform is taken out, the rotary motor 301 drives the rotating plate 302 to rotate 180 degrees, so that the workpiece to be processed on the other placement platform is rotated to a suitable position so that the loading rack 403 can pick up the material, realizing the rapid switching of material preparation.

[0020] The working principle and usage process of this utility model are as follows: First, the rotary motor 301 at the bottom of the material preparation rack 3 drives the rotary plate 302 to rotate. The operator places the rack support seat to be processed on the placement platform at both ends of the rotary plate 302. After the rack support seat on one placement platform is taken out, the rotary motor 301 drives the rotary plate 302 to rotate 180 degrees, so as to realize the rapid switching of material preparation. The translation component 5 drives the loading and unloading component 4 to move horizontally, so that the loading rack 403 is close to the material preparation rack 3. The electric push rod 405 of the end clamping part retracts, driving the connecting plate 406 to move, so that the two clamping plates 407 open. After the loading rack 403 moves to a suitable position above the placement table, the electric push rod 405 extends, pushing the connecting plate 406 to move in the opposite direction, and the two clamping plates 407 close to clamp the rack support seat. The translation component 5 continues to drive the loading and unloading component 4 to move, so that the loading rack 403 moves above the riveting table 2. The hydraulic diagonal rod 402 extends and pushes the loading rack 403 to move downward along the guide column 401, placing the rack support seat into the riveting groove. During this process, the pre-pressing part 409 pre-presses it. The riveting column 202 moves downward under the action of the hydraulic cylinder 6 to rivet the rack support seat. After the riveting is completed, the end clamping part of the unloading frame 404 works, the electric push rod 405 retracts to open the clamping plate 407, the translation component 5 drives the unloading component 4 to move, so that the unloading frame 404 moves above the riveting table 2, and the electric push rod 405 extends to close the clamping plate 407 to clamp the rack support seat. The translation component 5 continues to drive the loading and unloading component 4 to move, so that the unloading rack 404 is located above the unloading ramp 201. The hydraulic ramp 402 retracts and pulls the loading rack 403 upward. Under the action of gravity, the unloading rack 404 places the rack support on the unloading ramp 201 and slides down to the designated position to complete the unloading.

[0021] In the above scheme, it should be noted that: the translation component 5 is an existing screw drive structure, and its specific structure is a publicly disclosed technology. The translation component 5 can perform forward or reverse transmission. The rotary motor 301, hydraulic diagonal rod 402, electric push rod 405 and hydraulic cylinder 6 are also existing products. The specific structure and working principle of the rotary motor 301, hydraulic diagonal rod 402, electric push rod 405 and hydraulic cylinder 6 are also publicly disclosed technologies, and will not be described in detail here. It should also be noted that the riveting device of this application is equipped with a mature control system that is already in use in the field. The circuit connection method and control principle between the control system and the translation component 5, the rotary motor 301, the hydraulic diagonal rod 402, the electric push rod 405 and the hydraulic cylinder 6 are common existing technical means. At the same time, the technical solution of this application does not involve the improvement of the control program, and adopts the existing control technology of electrical components for riveting of rack and pinion support seats, which will not be described in detail here.
