Technical Field
[0001] This application relates to the field of riveting technology, specifically to a pin riveting device for an automotive sunroof guide rail. Background Technology
[0002] Car sunroof guide rails are devices installed on the roof of a car to guide the sunroof glass to slide smoothly along a fixed track, ensuring smooth and precise opening and closing. They are mostly made of metal. After the metal car sunroof guide rails are cut to a fixed length, they also need to undergo processes such as grooving, drilling, pin riveting, and grinding.
[0003] The grooving and pin riveting processes for existing automotive sunroof guide rails are carried out separately and require the use of specialized equipment. This necessitates two loading and unloading processes, making the processing steps cumbersome and impacting efficiency. Furthermore, each process requires repositioning before starting, which is time-consuming, labor-intensive, and increases dimensional deviations, thus affecting processing accuracy. In addition, the equipment responsible for grooving and pin riveting occupies a significant amount of space and increases purchase costs, necessitating a solution. Summary of the Invention

[0019] The transmission unit 65 includes a bottom plate 6514 horizontally fixed to the upper end of the riveting column 4, a transition plate 6513 vertically fixed to the top of the bottom plate 6514, a transmission plate 6512 vertically fixed to the left side of the transition plate 6513, two guide rods 658 rotatably connected to the transmission plate 6512 and arranged vertically and parallel to each other, a first suspension rod 6510 rotatably connected to the end of the upper guide rod 658, a diagonal brace 6511 rotatably connected to the transmission plate 6512 and arranged concentrically with the root of the lower guide rod 658, and a second suspension rod 656 rotatably connected to the end of the diagonal brace 6511. The ends of the first suspension rod 6510 and the second suspension rod 656 are rotatably connected to the left inner wall of the frame 2 and are distributed vertically and vertically respectively.
[0020] The transmission unit 65 also includes a synchronizing rod 659, a third suspension rod 655, and a first force transmission rod 654, which are rotatably connected to the end of a lower guide rod 658. The end of the synchronizing rod 659 is rotatably connected to the end of an upper guide rod 658 and is concentrically arranged with the root of the first suspension rod 6510. The end of the third suspension rod 655 is rotatably connected to the left inner wall of the frame 2 and is concentrically arranged with the end of the second suspension rod 656. The end of the synchronizing rod 659 is rotatably connected to the end of an upper guide rod 658.
[0021] The transmission unit 65 also includes a second force transmission rod 657 rotatably connected to the end of the diagonal brace 6511 and concentrically arranged with the root of the second suspension rod 656, a traction shaft 651 laterally and concentrically fixed to the left side of the driven pulley 63, an input rod 652 rotatably connected to the end of the traction shaft 651, and an amplifying rod 653 rotatably connected to the end of the input rod 652. The ends of the second force transmission rod 657 and the first force transmission rod 654 are rotatably connected to the end of the amplifying rod 653 and concentrically arranged.
[0022] The end of the second force transmission rod 657 or the first force transmission rod 654 is also fixed with a counterweight arm 66, the end of the counterweight arm 66 is set to the rear, and the end of the counterweight arm 66 is also fixed with a first counterweight block 67.
[0023] The end of the first suspension rod 6510 is further extended to the rear, and the end of the extension 65101 is fixed with a second counterweight 68 located inside the frame 2.
[0024] Working principle: The traction motor 61 in the drive traction assembly 6 rotates its rotating shaft, which in turn drives the traction shaft 651 in the transmission unit 65 to rotate clockwise via the drive pulley 62, the driven pulley 63 and several belts 64. This causes the end of the amplifying rod 653 to swing clockwise via the input rod 652. This, in turn, causes the end of a guide rod 658, the end of the diagonal brace 6511 and the end of the synchronizing rod 659 to swing clockwise via the first force transmission rod 654 and the second force transmission rod 657. This causes the roots of the two guide rods 658 to swing vertically upward via the first suspension rod 6510 and the second suspension rod 656. This, in turn, causes the riveting column 4 to move vertically upward via the transmission plate 6512, the transition plate 6513 and the bottom plate 6514.
[0025] It is worth mentioning that: during the rotation of the driven pulley 63, the end of the rocker arm 75 in the punching assembly 7 will also rotate eccentrically, thereby driving the half-shaft gear 74 to rotate clockwise, thereby driving the rack 73 to move vertically upward, and thus driving the lifting block 71 and the pressure block 72 to move upward. When the lifting block 71 and the pressure block 72 rise to the highest point, the traction motor 61 is turned off.
[0026] Next, the sunroof guide rail is placed horizontally into the positioning groove 51 on the positioning block 5, with one end of the sunroof guide rail abutting against the inner wall of the closed end of the positioning groove 51. At this time, the pin pre-installed on the sunroof guide rail is located directly below the rivet column 4. Then, the rotating shaft of the traction motor 61 is driven to rotate. At this time, the end of the rocker arm 75 begins to swing in the opposite direction. Similarly, the rocker arm 75 drives the half-shaft gear 74 to rotate counterclockwise, thereby driving the lifting block 71 and the pressure block 72 to move downwards. This causes the end of the limiting block 77 to press against the sunroof guide rail. At the same time, the end of the punching strip 76 extends into the positioning groove 51 and punches the inner wall of the bottom surface of the sunroof guide rail to complete the grooving. Meanwhile, the end of the input rod 652 begins to swing in the opposite direction, thereby driving the rivet column 4 to move vertically downwards, thereby riveting the pin to the bottom to fix it on the sunroof guide rail.
[0027] Next, the rotating shaft of the traction motor 61 continues to rotate, and the end of the rocker arm 75 and the end of the input rod 652 begin to swing forward again. In turn, the riveting column 4, the lifting block 71 and the pressure block 72 move upward in the same way until all three are at their highest point. Then, the riveted and punched car sunroof guide rail is removed and placed into the next car sunroof, thus forming a cycle. The purpose of setting the first counterweight 67 and the second counterweight 68 is to speed up the upward movement and reset of the riveting column 4, the lifting block 71 and the pressure block 72.
[0028] In addition to the pin riveting function, this invention also integrates a punching component 7 for slotting the car sunroof guide rail. Thus, only one machine is needed to complete the slotting and pin riveting processes of the car sunroof guide rail in sequence. Therefore, only one loading, unloading and positioning process is required, which simplifies the processing steps and ensures processing efficiency and accuracy. In addition, it saves space and reduces purchase costs.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
