Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment for automobile assembly lines, and in particular to a protective device for automobile body paint assembly. Background Technology

[0002] In the automotive manufacturing industry, the assembly process for automotive body paint requires high quality and precision. During the paint application process, meticulous protection of the vehicle body surface is necessary to prevent scratches, stains, and other problems. Traditional protection mainly relies on manual masking or fixed protective devices, but these methods are difficult to adapt to the complex curved structure of the automotive body and are inefficient, failing to meet the automation requirements of modern automotive production lines.

[0003] In existing technologies, protective equipment is typically secured using methods such as magnetic adsorption or mechanical clamps. Magnetic adsorption relies on the magnetic connection of the vehicle's metal parts, but it may attract debris, causing scratches to the paint, and it also has poor conformability to the curved surfaces of the vehicle body. Mechanical clamps, on the other hand, often use a fixed-angle design, securing themselves to specific locations on the vehicle body with bolts or clips. While they provide strong fixing force, their angle adjustment flexibility is poor, and they cannot adapt to changes in the curvature of different areas of the vehicle body.

[0004] However, current technologies, whether magnetic adsorption or mechanical clamps, cannot effectively solve the problem of fitting protective equipment to the curved surface of the car body. Especially in complex areas of the car body, such as doors, roofs, or fenders, where the curvature varies greatly, existing fixing methods often result in the protective equipment not fitting tightly to the car body. This leads to the risk of paint contamination or scratches during the painting process, severely restricting the efficiency and quality of automotive painting processes. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a protective device during the final assembly of automotive body paint, aiming to improve the problem of effective fit between the protective device and the curved surface of the vehicle body in complex areas such as doors, roofs, or fenders, where the curvature varies greatly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a protective device for the final assembly of automotive body paint, comprising a protective plate, a tray provided on one side of the outer wall of the protective plate, and an angle adjustment component provided on one side of the outer wall of the tray; The angle adjustment assembly includes a connecting column, the lower end of which is fixedly connected to the upper surface of the outer wall of the tray, and a rotating disk fixedly connected to the upper end of the connecting column. A fixed ball head is slidably connected to the upper surface of the rotating disk, and a fixed disk is fixedly connected to one side of the outer wall of the fixed ball head. A bolt is fixedly connected to the lower surface of the outer wall of the fixed disk, and a fixed frame is fixedly connected to one side of the outer wall of the bolt. A limit frame is fixedly connected to the lower surface of the outer wall of the fixed frame.

[0007] Furthermore, a second fixing frame is fixedly connected to the lower surface of the outer wall of the protective plate, a spring is provided on the inner wall of the second fixing frame, a limit plate is fixedly connected to one side of the outer wall of the spring, and a stop bar is fixedly connected to the inner wall of the limit plate.

[0008] Furthermore, a pull column is slidably connected to the inner wall of the tray, and a suction cup is fixedly connected to the lower end of the pull column.

[0009] Furthermore, a limiting rod is fixedly connected to the inner wall of the fixed disk, and the inner wall of the limiting frame is in contact with the outer wall of the rotating disk.

[0010] Furthermore, the outer wall of the rotating disk is provided with a groove, which fits into the outer wall of the fixed ball head.

[0011] Furthermore, the second fixing frame is provided with a slot, which fits against the outer wall of the limiting rod.

[0012] Furthermore, the inner wall of the second fixed frame is provided with a groove, and the stop rod is slidably connected to the inner wall of the groove.

[0013] Furthermore, a fixed shaft is fixedly connected to the upper end of the pulling column, and the two ends of the fixed shaft are rotatably connected with latches.

[0014] This utility model has the following beneficial effects: In this invention, a suction cup is used to adhere to the car body. Under the restriction of the limiting frame, the rotating disk slides on the fixed ball head, thereby driving the connecting column and allowing the tray to rotate accordingly. This enables flexible adjustment of the suction cup angle to adapt to the curved surface of the car body. By pulling the latch, the pulling column moves upward and pulls the suction cup, creating a negative pressure between the suction cup and the outer wall of the car body, thus firmly adhering it. This allows the protective plate to be fixed to the surface of the car body while adapting to the curved structure of the car body.

[0015] In this invention, by compressing the spring, the limiting plate causes the stop bar to slide within the fixed frame two, thereby allowing the upper limit bar of the fixed plate to slide into the slot. Under the push of the spring, the limiting bar is locked into the slot. Replacement only requires removing the limiting bar from the slot. Under the push of the spring, the angle adjustment component can be released from the limitation of the fixed frame two, realizing the quick installation and replacement of the protective plate and the angle adjustment component, improving assembly efficiency and reducing operation difficulty.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-5 This utility model provides an embodiment of a protective device for the final assembly of automotive body paint, including a protective plate 1. The protective plate 1 can directly cover and protect the automotive body paint area to prevent damage to the paint surface during assembly. A tray 5 is provided on one side of the outer wall of the protective plate 1. A pulling column 4 is slidably connected to the inner wall of the tray 5. A fixed shaft 3 is fixedly connected to the upper end of the pulling column 4. Locks 2 are rotatably connected to both ends of the fixed shaft 3. The locks 2 are rotatably connected to the fixed shaft 3. The fixed shaft 3 can rotate flexibly when the locks 2 are turned, thereby pulling the pulling column 4. A suction cup 14 is fixedly connected to the lower end of the pulling column 4. The suction cup 14 adheres to the surface of the vehicle body by adsorption to ensure that the protective device will not shift during the paint application process. An angle adjustment component is provided on one side of the outer wall of the tray 5. The angle adjustment assembly includes a connecting post 13, the lower end of which is fixedly connected to the upper surface of the tray 5. This fixed connection allows the tray 5 to rotate with the connecting post 13 during angle adjustment. A rotating disk 11 is fixedly connected to the upper end of the connecting post 13. The outer wall of the rotating disk 11 has a groove, allowing a fixed ball head 8 to slide within the groove. The groove fits against the outer wall of the fixed ball head 8. The fixed ball head 8 is slidably connected to the upper surface of the outer wall of the rotating disk 11. A fixed disk 6 is fixedly connected to one side of the outer wall of the fixed ball head 8, allowing the rotating disk 11 to slide... When in motion, the fixed ball head 8 can remain stable. The inner wall of the fixed plate 6 is fixedly connected to the limit rod 7. The lower surface of the outer wall of the fixed plate 6 is fixedly connected to the bolt 10. The fixing of the bolt 10 realizes the connection between the fixed frame 9 and the fixed plate 6. The fixed frame 9 is fixedly connected to one side of the outer wall of the bolt 10. The lower surface of the outer wall of the fixed frame 9 is fixedly connected to the limit frame 12. The limit frame 12 can fit against the outer wall of the rotating plate 11 to form a limit barrier, ensuring that the rotating plate 11 is always within the control range of the fixed ball head 8 during the angle adjustment process. The inner wall of the limit frame 12 fits against the outer wall of the rotating plate 11.

[0020] Specifically, by setting up a protective plate 1 to directly cover and protect the paint area of ​​the car body, the paint surface is effectively prevented from being damaged during assembly. By allowing the rotating disk 11 to slide on the fixed ball head 8, the connecting column 13 can rotate under the restriction of the limit frame 12, so that the tray 5 and the suction cup 14 can rotate with the connecting column 13, and the suction cup 14 can adapt to the curvature of the car body to ensure a tight fit with the car body surface.

[0021] Reference Figures 1-5 A fixing frame 15 is fixedly connected to the lower surface of the outer wall of the protective plate 1. The fixing frame 15 can accommodate the movement of the structure inside. The inner wall of the fixing frame 15 is provided with a groove and a slot is provided on the fixing frame 15. The slot fits against the outer wall of the limiting rod 7. The slot allows the limiting rod 7 to be locked and fixed, ensuring that the protective plate 1 and the angle adjustment component remain connected and preventing loosening. The fixing frame 15 is provided with a spring 16. A limiting plate 17 is fixedly connected to one side of the outer wall of the spring 16. A stop rod 18 is fixedly connected to the inner wall of the limiting plate 17. When the spring 16 generates elastic force on the limiting plate 17, the stop rod 18 prevents the limiting plate 17 from disengaging. The stop rod 18 is slidably connected to the inner wall of the groove.

[0022] Specifically, the second fixing frame 15 is fixedly connected to the lower surface of the outer wall of the protective plate 1. By applying pressure to the inner limiting plate 17, the spring 16 is compressed, thereby achieving the clamping and fixing of the inner wall groove of the second fixing frame 15 with the limiting rod 7. When the limiting rod 7 disengages from the groove, the spring 16 returns to its original state, thereby pushing the limiting plate 17, which in turn generates a thrust on the fixing plate 6, causing the fixing plate 6 to disengage from the second fixing frame 15, thus realizing the connection and disassembly of the protective plate 1 and the angle adjustment assembly.

[0023] Working principle: When the protective plate 1 needs to protect the car body, the suction cup 14 needs to be attached to the car body. Because the car body has a curved surface, the angle of the suction cup 14 needs to be adjusted. At this time, the rotating tray 5 drives the connecting column 13, so that the rotating disk 11 fixedly connected to the other end of the connecting column 13 can slide on the fixed ball head 8. The limiting frame 12 is fixedly connected to the fixed frame 9 and fixed to the lower surface of the outer wall of the fixed disk 6 by bolts 10 to prevent the rotating disk 11 from falling off when sliding. After adjusting to the appropriate position, the locking buckle 2 is pulled to move the pulling column 4 upward under the fixation of the fixed shaft 3, thereby pulling the suction cup 14, so that a negative pressure is formed between the suction cup 14 and the outer wall of the car body, so that it can be attracted.

[0024] Furthermore, when installing or removing the protective plate 1 and the angle adjustment assembly, pressure is applied to the limiting plate 17, which compresses the spring 16, causing the stop rod 18 to slide on the inner wall of the second fixing frame 15. At this time, the limiting rod 7 slides along the groove on the inner wall of the second fixing frame 15 with the fixing plate 6, reaching the bottom of the groove, so that the limiting rod 7 is engaged in the slot. When replacing, the fixing plate 6 applies pressure to the limiting plate 17, which compresses the spring 16, thereby causing the limiting rod 7 to disengage from the slot. At this time, the spring 16 returns to its original position, thereby pushing the stop rod 18, causing the fixing plate 6 to disengage, thus achieving the disassembly of the protective plate 1 and the angle adjustment assembly.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
