[0017] like Figure 1-2 As shown, the car roof assembly pressing fixture includes a support platform 1 and a pressing frame 2. A car roof positioning frame 3 is mounted on the support platform 1. A top plate 4 is located above the support platform 1, and the support platform 1 is fixedly connected to both sides of the top plate 4 via vertical plates 5. The pressing frame 2 is located between the top plate 4 and the support platform 1. The pressing frame 2 is driven to move up and down by a hydraulic mechanism 6 fixed to the top plate 4. Mounting plates 7 are provided around the pressing frame 2, and several upper mold frames 8 are detachably mounted on the mounting plates 7. Upper mold cylinders 9 are connected to the upper mold frames 8, and a clamping cylinder 10 is connected to one side of each upper mold cylinder 9. The working shaft of the clamping cylinder 10 extends into the upper mold cylinder 9 and is fixedly connected to a clamping plate 11. The car roof is snapped onto the car roof positioning frame 3 for positioning. The plastic brackets to be pressed are placed into the upper mold cylinders 9 and clamped and fixed using the clamping cylinder 10. Both sides of the support platform 1 allow operators to place the plastic bracket into the upper mold cylinder 9, improving the feeding efficiency of the plastic bracket. The hydraulic mechanism 6 is a hydraulic cylinder that drives the pressing frame 2 to descend, causing the plastic bracket to align with a specific position on the car roof and press against it. After pressing, the clamping cylinder 10 releases the plastic bracket, the pressing frame 2 rises, and the car roof is removed from the support platform 1.

[0018] Furthermore, one end of the upper mold frame 8 is detachably connected to a connecting plate 12 via several bolts, and the other end is detachably connected to an upper mold cylinder 9 via several bolts. The mounting plate 7 is provided with sliding grooves 13, and sliders 14 are fixedly connected to the connecting plate 12. The sliders 14 are confined within their respective sliding grooves 13 and can move within them. The connecting plate 12 is provided with several threaded holes 15, and tightening bolts 16 are threaded into these holes 15, respectively pressing against the mounting plate 7. The position and number of upper mold frames 8 can be adjusted as needed, and upper mold frames 8 with different angles and heights can also be replaced. The specifications of the upper mold cylinder 9 can also be adjusted as needed.

[0019] Furthermore, several upper guide rods 17 are fixedly connected around the perimeter of the pressing frame 2, and several upper guide sleeves 18 are provided on the top plate 4. The upper guide rods 17 and upper guide sleeves 18 correspond one-to-one, and the upper guide rods 17 are inserted into the corresponding upper guide sleeves 18. The upper guide rods 17 improve the stability of the pressing frame 2 during movement.

[0020] Furthermore, the car roof positioning frame 3 has several lower guide rods 19 on both sides, and the pressing frame 2 has several lower guide sleeves 20 on both sides. The lower guide rods 19 and lower guide sleeves 20 correspond one-to-one and are inserted into the corresponding lower guide sleeves 20. The lower guide rods 19 further improve the stability of the pressing frame 2 during its up-and-down movement, enabling the plastic bracket to be accurately pressed onto the car roof.

[0021] Furthermore, the car roof positioning frame 3 is composed of several contoured blocks 21, which are fixed to the support platform 1 by several positioning bolts. The car roof positioning frame 3 is customized according to the specifications and model of the car roof. When changing models, the original car roof positioning frame 3 is removed and the new car roof positioning frame 3 is installed.

[0022] Furthermore, the car roof positioning bracket 3 is provided with a buffer pad 22. The buffer pad 22 provides a cushioning effect during the process of the plastic bracket being pressed onto the car roof, and at the same time can protect the car roof from being damaged and scratched.

[0023] Furthermore, the support platform 1 is provided with several limiting posts 23, which are located below the pressing frame 2. The limiting posts 23 prevent the pressing frame 2 from excessively descending and damaging the car roof.

[0024] Furthermore, several fixed threaded tubes 24 are fixed on the support platform 1, and limiting posts 23 correspond to the fixed threaded tubes 24. The lower end of the limiting post 23 is inserted into the corresponding fixed threaded tube 24 and threadedly connected to the corresponding fixed threaded tube 24. The height of the limiting post 23 is adjustable to accommodate different models and specifications of car roofs.
