[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] like Figures 1-4 As shown, the present invention discloses an adaptive pneumatic rolling gun for installing sealing strips on the tailgate of a car. The pneumatic rolling gun includes a mounting part 1, a drive mechanism 2, an adjustment mechanism 12, a limiting mechanism 16, and a first rotating shaft 9 and a second rotating shaft 10 driven by the drive mechanism 2. The first rotating shaft 9 and the second rotating shaft 10 are arranged vertically, and the distance between the first rotating shaft 9 and the second rotating shaft 10 is adjusted by the adjustment mechanism 12. Rollers 20 are also provided on both sides of the first rotating shaft 9 and the second rotating shaft 10. The rollers 20 are rotatably connected to the mounting base 21, and the mounting base 21 is fixed on the mounting part 1.

[0020] The drive mechanism 2 drives the first rotating shaft 9 and the second rotating shaft 10 to rotate. The adjustment mechanism 12 adjusts the distance between the first rotating shaft 9 and the second rotating shaft 10. The limiting mechanism 16 limits the first rotating shaft 9 and the second rotating shaft 10 after the distance is adjusted, keeping them at a constant distance. The roller 20 performs the rolling installation of the sealing strip. When using this pneumatic rolling gun, firstly, the sealing strip is placed on the tailgate part of the car. Then, the first rotating shaft 9 and the second rotating shaft 10 are secured on both sides of the part, and the distance between the first rotating shaft 9 and the second rotating shaft 10 is adjusted by the adjustment mechanism 12 to adapt to the width of the part. At this time, the roller 20 contacts the upper surface of the sealing strip. After starting the drive mechanism 2, the first rotating shaft 9 and the second rotating shaft 10 rotate forward, and the roller 20 rolls over the upper surface of the sealing strip, thus pressing the sealing strip tightly against the sealing area, ensuring the firmness of the sealing strip and the accuracy of its fixed position.

[0021] The drive mechanism 2 includes a pneumatic torque wrench 3, a steering drive assembly connected to the output shaft of the pneumatic torque wrench 3, an intermediate gear 6 meshing with the steering drive assembly, and a first drive gear 7 and a second drive gear 8 meshing with the intermediate gear 6. A first rotating shaft 9 is fixedly connected to the first drive gear 7, and a second rotating shaft 10 is fixedly connected to the second drive gear 8. The steering drive assembly includes a first bevel gear 4 and a second bevel gear 5. The first bevel gear 4 is fixedly connected to the output shaft of the pneumatic torque wrench 3, and the second bevel gear 5 is coaxially arranged with the intermediate gear 6.

[0022] In the above scheme, after the pneumatic torque wrench 3 is activated, the pneumatic torque wrench 3 drives the first bevel gear 4 to rotate, the first bevel gear 4 drives the second bevel gear 5 to rotate, the second bevel gear 5 drives the intermediate gear 6 to rotate, and the intermediate gear 6 then drives the first drive gear 7 and the second drive gear 8 to rotate, thereby realizing the second rotation and the rotation of the second rotating shaft 10.

[0023] Both the first drive gear 7 and the intermediate gear 6 are provided with connecting shafts 11. The adjusting mechanism 12 includes a rotating block 13 and a lifting cylinder 14 that presses against the rotating block 13. The rotating block 13 is provided with two mounting holes, and the rotating block 13 is sleeved on the connecting shaft 11 of the first drive gear 7 and the intermediate gear 6 through the two mounting holes. The bottom of the rotating block 13 is provided with a limiting groove 15, and the lifting cylinder 14 is located in the limiting groove 15. By lifting or lowering the lifting cylinder 14, the rotating block 13 is raised or lowered, thereby realizing the distance adjustment between the first rotating shaft 9 and the second rotating shaft 10. During the adjustment process, the limiting mechanism 16 limits the movement to prevent the adjusted distance from shifting.

[0024] The limiting mechanism 16 includes a limiting block 17 and a limiting spring 18, one end of which is in pressure contact with the limiting block 17 and the other end of which is in pressure contact with the rotating block 13. The limiting spring 18 is disposed on the same side as the lifting cylinder 14, and the limiting block 17 is provided with a slot 19 for the limiting spring 18 to extend into.
