The posture position of the curved panel body 5 can be obtained through a common posture sensor on the market. The rotation of the motor 24 drives the support frame 3 to rotate, which can drive the curved panel body 5 to rotate along the axis of the connecting shaft 19, thereby adjusting the riveting range. In order to meet the riveting assembly requirements of the multi-conical curved panel body 5, an adjustment drive structure for adjusting the pitch angle of the connecting shaft 19 is provided between the upper wall of the rotating sleeve 18 and the upper wall of the slide 12. The adjustment drive structure includes a first rotating seat 20, a second rotating seat 21 and a third cylinder 22. The upper wall of the slide 12 and close to the left wall is fixedly connected with a mounting seat 16.

After the curved surface of the curved panel body 5 is riveted, when the conical surface needs to be riveted, the shaft is extended or retracted by the third cylinder 22, and the rotating sleeve 18 is pulled to rotate along the axis of the rotating shaft 17, thereby adjusting the pitch angle of the support frame 3, and adjusting the conical surface of the curved panel body 5 to be parallel to the horizontal plane, which facilitates the riveting operation of the multi-conical curved panel body 5. The third cylinder 22 drives the rotating sleeve 18 to rotate in a very large range, and the pitch angle adjustment degree is large; The support frame 3 is fixedly connected to one end of the support plate 2 away from the connecting shaft 19. The support frame 3 is U-shaped when viewed from above, and the bottom of the U is connected to the connecting shaft 19.

The curved panel body 5 is supported from the inside by multiple groups of inner support frames 4. The upper wall of the support frame 3 is provided with multiple groups of clamping components for clamping the curved panel body 5. The upper wall of the support frame 3 is also provided with a positioning structure for positioning the curved panel body 5. The positioning structure is a common positioning pin and positioning block on the market, which can position the curved panel body 5 in the left and right directions. Since it is a common technology, it is not drawn in the schematic diagram of this embodiment. The clamping component includes a stopper 11, a fixing seat 6, and a pressing plate 8. The stopper 11 is fixedly connected to the upper wall of the support frame 3, the fixed seat 6 is fixedly connected to the upper wall of the support frame 3 and is located on the side of the stopper 11 away from the center of the front-rear direction of the support frame 3, the pressing plate 8 is slidably connected to the side of the fixed seat 6 facing the stopper 11 through two sets of guide rods 7, and the fixed seat 6 is away from the side of the stopper 11 and is fixedly connected with a first cylinder 10 between the two sets of guide rods 7. The pressing plate 8 is driven to approach and move away from the stopper 11 by the extension and retraction action of the shaft of the first cylinder 10. After the curved panel body 5 is placed on the upper wall of the support frame 3, the shaft of the first cylinder 10 is extended to drive the pressing plate 8 to approach the outer wall of the curved panel body 5 until the pressing plate 8 presses the curved panel body 5 against the side wall of the stopper 11; In order to avoid crushing the outer wall of the curved panel body 5, a buffer pad 9 is fixedly connected to the side of the pressure plate 8 facing the stopper 11. The buffer pad 9 is a rubber pad, which can play a protective role and prevent the outer wall of the curved panel body 5 from being crushed; In order to accurately control the clamping force, a rectangular hole is provided on the inner wall of the buffer pad 9, and a pressure sensor 26 for detecting the clamping pressure is fixedly connected to the side of the pressure plate 8 facing the stopper 11 and located inside the rectangular hole. The clamping force of the curved plate body 5 can be more accurately controlled by the pressure sensor 26 to ensure that the clamping can be achieved without causing any damage. According to the above assembly method of the riveting assembly equipment for the curved plate, the assembly method includes the following steps: S1, clamping the curved panel body 5, placing multiple curved panel bodies 5 that need to be riveted and assembled on the upper wall of the support frame 3, supporting them through the inner support frame 4, and positioning them through the positioning structure. After being placed in place, the first cylinder 10 drives the pressing plate 8 to move toward the stopper 11, and the edge of the curved panel body 5 is clamped and fixed by the pressing plate 8 and the stopper 11, and the clamping force is detected by the pressure sensor 26; S2, driving the support frame 3 to move between the lower riveting gun moving platform and the upper drilling riveting frame through the translation driving device, and drilling and riveting the curved panel body 5 by the cooperation of the lower riveting gun and the upper drilling riveting gun; S3, when the curved panel body 5 is adjusted to the riveted position along its curved surface, the motor 24 is rotated to drive the support frame 3 to rotate at a preset angle, thereby adjusting the riveted position of the curved panel body 5. The angle at which the support frame 3 rotates along the axis of the motor 24 is the unfolding angle of the curved surface of the curved panel body 5; S4. When the curved panel body 5 is riveted at the conical surface, the shaft is extended and retracted by the third cylinder 22, and the rotating sleeve 18 is pulled to rotate along the axis of the rotating shaft 17 at a preset angle to adjust the pitch angle of the connecting shaft 19 and the support frame 3. At the same time, the slide 12 is driven to rise or fall by the second cylinder 15, so that the position to be riveted is at a suitable height after the pitch angle of the curved panel body 5 is adjusted. The pitch angle adjustment value of the support frame 3 is the taper of the conical surface of the curved panel body 5.

[0022] Working principle: The four sets of slide rails 14 and the four sets of sliding seats 13 can ensure the stability of the rise and fall of the slide 12. At the same time, after the curved panel body 5 is placed on the support frame 3, the connection between the slide 12 and the drive seat 1 is guaranteed to be stable. The slide 12 is driven to rise and fall by the second cylinder 15 extending the shaft and retracting it. After the third cylinder 22 adjusts the pitch angle of the support frame 3, the slide 12 is driven to rise or fall by the second cylinder 15 to keep the height of the part to be riveted after the support frame 3 adjusts the pitch angle within a suitable range. The axis center of the curved surface of the curved panel body 5 is colinear with the axis center of the connecting shaft 19. The attitude position of the curved panel body 5 can be obtained through the common attitude sensor on the market. The rotation of the motor 24 drives the support frame 3 to rotate, which can drive the curved panel body 5 to rotate along the axis center of the connecting shaft 19, thereby adjusting the riveting range. The connecting shaft 19 is extended by the third cylinder 22 to extend and retract the shaft to adjust the pitch angle. After the curved surface of the curved panel body 5 is riveted When riveting is required at the conical surface, the shaft is extended or retracted by the third cylinder 22, and the rotating sleeve 18 is pulled to rotate along the axis of the rotating shaft 17, thereby adjusting the pitch angle of the support frame 3, and adjusting the conical surface of the curved panel body 5 to be parallel to the horizontal plane, which is convenient for the riveting operation of the multi-conical curved panel body 5. The third cylinder 22 drives the rotating sleeve 18 to rotate with a very large range of motion, and the pitch angle adjustment freedom is large. After the curved panel body 5 is placed on the upper wall of the support frame 3, the shaft is extended by the first cylinder 10 to drive the pressing plate 8 to approach the outer wall of the curved panel body 5 until the pressing plate 8 presses the curved panel body 5 against the side wall of the block 11. A buffer pad 9 is fixedly connected to the side of the pressing plate 8 facing the block 11. The buffer pad 9 is a rubber pad. The rubber pad can play a protective role to prevent the outer wall of the curved panel body 5 from being crushed. The clamping force of the clamping curved panel body 5 can be more accurately controlled by the pressure sensor 26 to ensure that it is clamped without being crushed.
