[0029] Please see Figure 1-7 This utility model provides a technical solution:

[0030] A riveting device for automotive parts includes a housing 1, a riveting head 2, and a second hydraulic rod 8. A position adjustment component 5 is fixedly connected to the right side of the housing 1, and a movable outer shell component 6 is fixedly connected to the left side of the position adjustment component 5. A support component 7 is installed inside the movable outer shell component 6. The movable outer shell component 6 includes a movable shell 61, a caster wheel 62 is fixedly connected to the bottom of the movable shell 61, a first spring 63 is fixedly connected to the inside of the movable shell 61, a rack 64 is fixedly connected to the inside of the movable shell 61, and a guide rail groove 65 is opened inside the movable shell 61.

An electromagnet plate 3 is fixedly connected to the bottom end of the second hydraulic rod 8. A rivet joint 2 is fixedly connected to the bottom end of the electromagnet plate 3. A car door panel accessory 4 is fixed inside the housing 1. Through the above settings, the planar motion structure can accurately control the position of the rivet joint 2, ensuring that the rivet joint 2 can be accurately aligned with the rivet point on the car door, thereby improving the riveting accuracy. At the same time, this structural design allows the riveting device to adapt to car doors of different sizes and shapes, enhancing the versatility and flexibility of the device.

[0032] As a further implementation of this solution, the position adjustment component 5 includes a base 51, a servo motor 52 fixedly connected to the inner side of the base 51, a top block 53 fixedly connected to the end of the main shaft of the servo motor 52, an electric telescopic rod 54 fixedly connected to the left side of the top block 53, the left side of the base 51 fixedly connected to the right side of the housing 1, the piston rod of the electric telescopic rod 54 fixedly connected to the right side of the movable housing 61, and a notch is opened on the inner side of the housing 1 near the electric telescopic rod 54. The electric telescopic rod 54 is located inside the notch of the housing 1. Through the above settings, the support component 7 can be quickly rotated and its position adjusted. This design not only improves the riveting efficiency, but also allows for flexible adjustment of the position of the support component 7 according to the shape of the car door and the riveting requirements, ensuring the stability and reliability of the riveting process.

[0033] As a further implementation of this solution, an extension rod is fixedly connected to the top of the movable rod 71, and a ball seat 76 is fixedly connected to the top of the extension rod of the movable rod 71. The ball seat 76 is spherical. With the above settings, the rivet joint 2 can automatically adjust the contact angle according to the curved shape of the car door when it contacts the car door, so as to better fit the car door surface, reduce deformation caused by excessive local pressure, and improve the riveting quality and stability.

[0034] As a further implementation of this solution, two-thirds of the ball seat 76 is embedded in the inner side of the through ball groove 79, which is opened inside the pressure seat 77. The bottom end of the pressure seat 77 is fixedly connected to the top end of the second spring 78, and the bottom end of the second spring 78 is fixedly connected to the top end of the movable rod 71. With the above arrangement, this embedded structure allows the ball seat 76 to rotate flexibly inside the through ball groove 79, while preventing the pressure seat 77 from detaching from the outside of the ball seat 76.

[0035] As a further implementation of this solution, the inner side of the movable shell 61 is hollow, the movable rod 71 slides on the upper end of the movable shell 61, the upper end of the first spring 63 is fixedly connected to the bottom end of the limiting slide plate 72, the left side of the toothed plate 74 is fixedly connected to a guide rod, the inner side of the limiting slide plate 72 is provided with a guide hole, and the guide rod of the toothed plate 74 slides inside the guide hole of the limiting slide plate 72. Through the above settings, the support component 7 moves upward under the magnetic attraction of the electromagnet plate 3. Through the cooperation of the first hydraulic rod 73, the toothed plate 74 and the rack 64, the support component 7 is fixed inside the movable shell component 6, thereby realizing the function of providing partial support for the car door panel accessory 4.

[0036] Workflow: When riveting the car door, i.e., the car door panel component 4, the housing 1 is equipped with an integrated control system. The position adjustment component 5 is electrically connected to the integrated controller of the housing 1. The car door panel component 4 is fixed to the inside of the housing 1 using existing clamps and bolts. The position of the riveting head 2 is controlled by the planar motion structure at the upper end of the housing 1. When the servo motor 52 is started, it drives the top block 53, the electric telescopic rod 54, the moving housing component 6, and the support component 7 to rotate as a whole. The extension of the electric telescopic rod 54 aligns the support component 7 vertically with the riveting head 2. The second hydraulic rod 8 is then activated. The moving electromagnet plate 3 and the rivet joint 2 move downwards. When the bottom end of the rivet joint 2 is in contact with the top end of the car door panel component 4, the electromagnet plate 3 is activated. The magnetic attraction force of the electromagnet plate 3 gradually increases, which controls the moving speed of the support component 7. The electromagnet plate 3 attracts the permanent magnet plate 75. Under the action of the magnetic attraction force, the support component 7 moves upward as a whole. When the pressure seat 77 is in contact with the bottom end of the car door panel component 4, the pressure seat 77 will rotate. The pressure seat 77 rotates outside the ball seat 76 through the through ball groove 79. The pressure seat 77 drives the multiple second springs 78 to move accordingly. The deformation of the bearing seat 77 is controlled by multiple second springs 78, which reset the bearing seat 77. The bearing seat 77 rotates outside the ball seat 76 through the ball groove 79. The rotation of the bearing seat 77 increases the contact area between the bearing seat 77 and the bottom of the car door panel component 4, preventing excessive local pressure on the car door panel component 4 from causing deformation. The limiting slide plate 72 slides inside the guide rail groove 65 to prevent the support component 7 from twisting, improving the stability of the riveting of the car door panel component 4. The limiting slide plate 72 drives the first spring 63 to extend, and the first spring 63 acts as a spring. The support component 7 serves to reset the entire assembly. After the support component 7 is attached to the car door panel accessory 4, the first hydraulic rod 73 is activated by the existing integrated controller. The first hydraulic rod 73 drives the toothed plate 74 to move towards the rack 64. When the toothed plate 74 meshes with the rack 64, it fixes the support component 7 inside the movable housing assembly 6. At this time, when the car door panel accessory 4 is riveted by the riveting joint 2, the support component 7 can prevent the car door panel accessory 4 from deforming locally due to the riveting pressure, ensuring that the quality and performance of the car door in the later assembly and use are not affected.
