[0036] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0037] A car tailgate alignment device includes a main frame 1; the main frame 1 is provided with a tailgate fixing structure for mounting tailgate 1-2 on the main frame 1 and a tailgate positioning mechanism 9 for connecting the main frame 1 to the car body frame; the present invention mainly uses the combination of the tailgate fixing structure and the tailgate positioning mechanism 9 to realize the automatic alignment operation during the assembly of tailgate 1-2.

[0038] In this utility model, the tailgate fixing structure is used for the assembly of the tailgate 1-2 to be installed on the centering device 1-1. Subsequently, it is combined with the tailgate positioning mechanism 9. Through the interaction between the tailgate positioning mechanism 9 and the vehicle frame 1-3, the centering device 1-1 drives the tailgate 1-2 to be installed to achieve centering operation at the rear of the vehicle.

[0039] Specifically, the car tailgate centering device disclosed in this utility model mainly includes a main frame 1. The main frame 1 serves as a basic support, facilitating the installation and placement of subsequent components. Simultaneously, the main frame 1 is provided with a tailgate fixing structure for mounting the tailgate 1-2 on the main frame 1, and a tailgate positioning mechanism 9 for connecting the main frame 1 to the vehicle frame. The tailgate fixing structure is mainly used for the stable connection of the tailgate 1-2 to the centering device 1-1, facilitating the movement of the centering device 1-1 and thus enabling the tailgate 1-2 to move, thereby achieving subsequent centering adjustment. Meanwhile, the tailgate positioning mechanism 9 is mainly used for mutual positioning between the centering device 1-1 and the vehicle frame 1-3, facilitating the centering operation by moving the tailgate 1-2 on the centering device 1-1 during subsequent use.

[0040] Furthermore, the tailgate fixing structure described in this utility model includes a tailgate clamping mechanism disposed on the main body frame 1; the tailgate clamping mechanism is mainly used for the stable placement of the tailgate 1-2 to be installed on the main body frame 1. The tailgate clamping mechanism described in this utility model includes a tailgate upper frame clamp 2 and / or a pneumatic suction cup 3 disposed on the main body frame 1; in this utility model, the tailgate upper frame clamp 2 and the pneumatic suction cup 3 can be used individually or in combination, the main purpose of which is to fix the tailgate 1-2 to be installed by adsorption or clamping, so as to ensure the stable placement of the tailgate 1-2 on the main body frame 1.

[0041] Meanwhile, the number and placement of the rear door upper frame clamp 2 and the pneumatic suction cup 3 in this utility model can be determined as needed; generally, two pneumatic suction cups 3 can be set on both sides of the main body frame 1; and one rear door upper frame clamp 2 can be set on the left and right sides above the main body frame 1; in subsequent use, the pneumatic suction cup 3 can adsorb the rear end face of the rear door 1-2 to be installed, and the rear door upper frame clamp 2 is clamped above the rear door 1-2 to be installed. Based on this cooperation, the rear door 1-2 to be installed can be adsorbed and clamped at multiple positions, ensuring the stability of the rear door 1-2 to be installed on the centering device 1-1.

[0042] In addition, the tailgate fixing structure described in this utility model also includes a guide limiting mechanism set on the main body frame 1; the guide limiting mechanism mainly limits the lateral position of the tailgate 1-2 to prevent the tailgate 1-2 to be installed from swaying laterally on the main body frame 1. The guide limiting mechanism in this utility model includes a limiting plate 5 set on the main body frame 1; one end of the limiting plate 5 is connected to the main body frame 1, and the other end extends freely; generally, the limiting plates 5 are arranged on both sides of the main body frame 1.

[0044] The Z-direction support mechanism 6 described in this utility model includes Z-direction support blocks 61 disposed on the main body frame 1. The Z-direction support blocks 61 are arranged at the lower edge of the main body frame 1. In subsequent use, the lower end of the rear door 1-2 to be installed is arranged on the corresponding Z-direction support block 61, thereby realizing the support of the Z-direction support block 61 for the lower end of the rear door 1-2 to be installed. At the same time, in this utility model, two Z-direction support blocks 61 are generally disposed on the main body frame 1. The two Z-direction support blocks 61 are distributed below the main body frame 1 and are spaced apart. This arrangement can ensure the stable support of the Z-direction support mechanism 6 for the rear door 1-2 to be installed.

[0045] Furthermore, in this utility model, the Z-direction support block 61 is connected to the main body frame 1 via the Z-direction adjustment cylinder 62; by setting the Z-direction adjustment cylinder 62, the longitudinal position of the Z-direction support block 61 can be adjusted as needed, and the longitudinal position of the rear door 1-2 to be installed on the Z-direction support block 61 can be easily realized, thereby realizing the adjustment of the longitudinal position of the rear door 1-2 as needed.

[0046] Furthermore, the tailgate fixing structure described in this utility model also includes an X-direction limiting mechanism disposed on the main body frame 1. The X-direction limiting mechanism mainly controls the gap between the main body frame 1 and the tailgate 1-2 to be installed, that is, to prevent the main body frame 1 from fitting together with the tailgate 1-2 to be installed. This arrangement not only facilitates the connection between the gas components and the tailgate 1-2 to be installed, but also facilitates the subsequent installation operation of the tailgate 1-2. Specifically, the X-direction limiting mechanism described in this utility model includes an X-direction reference block 7. One end of the X-direction reference block 7 is connected to the main body frame 1, and the other end extends away from the main body frame 1. The X-direction reference block 7 acts as a support block or a shim block, and is arranged on the side of the main body frame 1 close to the tailgate 1-2 to be installed, thereby realizing the supporting function of the tailgate 1-2 to be installed.

[0047] Furthermore, the tailgate positioning mechanism 9 described in this utility model includes a positioning hook pin 91 mechanism disposed on the main body frame 1; the positioning hook pin 91 mechanism plays a preliminary positioning role, facilitating the initial connection between the vehicle frame and the centering device 1-1, and achieving a coarse positioning function. Simultaneously, the positioning hook pin 91 mechanism in this utility model includes a positioning hook pin 91; the positioning hook pin 91 is connected to a hook pin drive cylinder 92; the hook pin drive cylinder 92 can drive the positioning hook pin 91 to move, facilitating the change of the positioning hook position during subsequent use; also, in this utility model, two positioning hook pin 91 mechanisms can generally be disposed on the main body frame 1, so that during subsequent use, the two positioning hook pin 91 mechanisms can be respectively inserted into the corresponding holes in the vehicle frame 1-3 to achieve coarse positioning operation of the centering device 1-1 and the tailgate 1-2 to be installed.

[0048] Furthermore, the rear door positioning mechanism 9 in this utility model includes a rotating linkage mechanism 10 disposed on the main body frame 1; the rotating linkage mechanism 10 includes a central connecting plate 104 disposed on the main body frame 1; the central connecting plate 104 is connected to a frame positioning mechanism, the frame positioning mechanism includes a body positioning pin 101, the body positioning pin 101 is connected to the main body frame 1 through a sliding mechanism; the sliding mechanism is connected to the central connecting plate 104 through a connecting rod 103, and the central connecting plate 104 is connected to a drive unit 105 for controlling the rotation of the central connecting plate 104; here the drive unit can be a motor or a rotary cylinder; this utility model, through the setting of the rotating linkage mechanism 10, and through the cooperative use of the two frame positioning mechanisms, allows the two body positioning pins 101 to be inserted into the tooling positioning holes on the vehicle body, thereby determining the YZ position of the centering device 1-1 on the vehicle body.

[0049] Furthermore, the rear door positioning mechanism 9 described in this utility model includes a body frame 1-3 clamping mechanism set on the main body frame 1; the setting of the body frame 1-3 clamping mechanism facilitates the clamping and fixing of the centering device 1-1 on the body frame 1-3.

[0050] Specifically, the clamping mechanism of the vehicle frame 1-3 in this utility model includes a fixed block and a movable block disposed on the main body frame 1. The movable block is connected to the fixed block through a vehicle clamping cylinder. In use, the fixed block is fixed on the main body frame 1. Subsequently, the movable block is moved to the side of the fixed block by the drive of the vehicle clamping cylinder, so as to facilitate the cooperation between the movable block and the fixed block, thereby realizing a stable connection between the vehicle frame 1-3 and the centering device 1-1.

[0051] Meanwhile, in this utility model, a corresponding number of body frame 1-3 clamping mechanisms can be set on the main body frame 1 as needed; this facilitates the installation and fixing of the centering device 1-1 on the body frame 1-3.

[0052] In this utility model, the centering device 1-1 also includes a tailgate positioning mechanism 4, which includes a tailgate positioning pin 41. The tailgate positioning pin 41 is connected to the main body frame 1 through a tailgate drive cylinder 42. At the same time, in this utility model, two tailgate positioning mechanisms 4 are provided on the main body frame 1. The tailgate positioning pins 41 in the two tailgate positioning mechanisms 4 are called the main tailgate positioning pin and the secondary tailgate positioning pin, respectively, due to their different positions.

[0053] Meanwhile, in this utility model, the first pneumatic switch 11 and the second pneumatic switch 12 are an assembly, each with multiple control buttons for controlling the opening and closing of multiple cylinders.

[0054] Meanwhile, in this utility model, the first pneumatic switch 11 and the second pneumatic switch 12 are connected to the main body frame 1 through the connecting bracket 2-1.

[0055] specific:

[0056] This utility model discloses a car tailgate alignment device; it mainly includes a main frame 1; the main frame 1 is provided with a tailgate fixing structure for mounting the tailgate 1-2 on the main frame 1 and a tailgate positioning mechanism 9 for connecting the main frame 1 to the car body frame; this utility model mainly uses the combined use of the tailgate fixing structure and the tailgate positioning mechanism 9 to realize the automatic alignment operation during the assembly of the tailgate 1-2.

[0057] As shown in the figure, the present invention discloses a car tailgate centering device; applicable to car bodies without fixed welded side panels, the tailgate 1-2 can be centered and installed using this device even without reference objects on both sides.

[0058] Specifically: the main frame 1 can provide corresponding support for the mechanism, and other corresponding components are installed on the frame as the main structure.

[0059] When using this mechanism, first slide the guide limit mechanism close to the theoretical position; then press the first pneumatic switch 11 to insert the main positioning pin and the secondary positioning pin of the rear door into the main and secondary positioning holes of the glass of the rear door 1-2 respectively, so as to determine the YZ position of the rear door 1-2. At the same time, the left Z-direction support block 61 and the right Z-direction support block 61 ensure that the rear door 1-2 has a certain lifting force to prevent it from sliding down.

[0060] The three X-axis reference blocks 7 are closely attached to ensure the theoretical X-axis position of the rear door 1-2.

[0061] This controls the pneumatic suction cups 3 to adsorb and install the tailgate 1-2, and the upper frame clamps 2 of each tailgate are used to clamp the tailgate 1-2 to be installed. At this point, the tailgate 1-2 to be installed is fixed on the centering device 1-1.

[0062] In this invention, the clamping and releasing of the rear door 1-2 can be operated by inserting, clamping and releasing buttons on the first pneumatic switch 11.

[0063] Then, after the centering device 1-1 is installed on the corresponding rear door 1-2 to be installed, it can be transported by a lifting device.

[0064] After the rear tailgate 1-2 is installed, the centering process begins on the vehicle body.

[0065] In use, by setting the positioning hook pin 91 mechanism, the left positioning hook pin 91 and the right positioning hook pin 91 are first inserted into the process hole of the water channel 1-3 of the body frame to determine the rough positioning.

[0066] Then control the rotating linkage mechanism 10 so that the drive unit 105 can be adjusted left and right on the left and right sliding mechanism through the left and right linkages 103, so that the left and right body positioning pins 101 are inserted when they meet the position of the tooling positioning hole on the body, and the tooling is determined to be in the YZ position on the body.

[0067] Finally, the second pneumatic switch 12 is operated to control the clamping mechanism of the body frame 1-3, and then the pin drive cylinder is controlled; causing the positioning hook pin 91 to flip out and clamp in the X direction; thus, the centering device 1-1, along with the rear door 1-2, is fixed on the body frame 1-3, and the whole set of actions is completed.

[0068] In this utility model, the clamping and releasing buttons on the second pneumatic switch 12 can operate the clamping and releasing operations of the corresponding components.

[0069] The core advantage of this utility model is that it can quickly place the rear door 1-2 in the center position of the rear cabin using a sliding mechanism with a connecting rod 103 without relying on reference objects for simplified adjustments.

[0070] The directional terms used in the above content, such as front end, rear end, X direction, Y direction, and Z direction, refer to the length, width, and height directions of a car in the O-XYZ coordinate system, respectively. The front end of each component refers to the end closest to the front of the car, and the rear end refers to the end closest to the rear of the car.

[0071] It should be understood that the use of the directional terms should not limit the scope of protection claimed in this application.

[0072] Obviously, the specific implementation of this utility model is not limited to the above-mentioned methods. Any non-substantial improvements made using the inventive concept and technical solution of this utility model are within the protection scope of this utility model.
