[0018] The present invention will be further described below with reference to the accompanying drawings:
[0019] A fixing device for processing automobile tailgates, such as Figure 1 As shown, the system includes a mounting chassis 1, on which two mounting plates 6 are fixed. A side clamp assembly and a support assembly are mounted above the mounting chassis 1. The side clamp assembly includes a transversely arranged bidirectional threaded rod A21, which has two sections of external threads with opposite directions. Both threaded sections of the bidirectional threaded rod A21 are threadedly connected to side clamping plates 22, which are positioned between the two mounting plates 6. A stepper motor A23, connected to the bidirectional threaded rod A21, is mounted on the top of the mounting chassis 1. The support assembly includes a bidirectional threaded rod B31 arranged in the front-rear direction, on which... The rod has two external threads with opposite directions. Both threaded sections of the bidirectional threaded rod B31 are threadedly connected to the support base plate 32. The support base plate 32 is slidably connected to the top of the mounting platform 6. The top of the mounting chassis 1 is equipped with a stepper motor B33 connected to the bidirectional threaded rod B31. Side upright plates 7 are fixed to the mounting chassis 1 on both sides of the support base plate 32. The support base plate 32 and the side upright plates 7 are slidably connected. The bidirectional threaded rod B31 is rotatably connected to the side upright plates 7. Front and rear upright plates 8 are fixed to the mounting chassis 1 on both sides of the side upright plates 7. The bidirectional threaded rod A21 is rotatably connected to the front and rear upright plates 8.
[0020] The combination of the bidirectional threaded rod A and the side clamping plate 22, driven by the stepper motor A, enables the side clamping plate 22 to move towards or away from each other, thereby laterally clamping the tailgate of the vehicle and accommodating tailgates of different widths. The design of the bidirectional threaded rod B and the support base plate 32, driven by the stepper motor B, allows the position of the support base plate 32 to be adjusted according to the length of the tailgate, ensuring stable support for tailgates of different sizes. The side upright plate 7 and the front and rear upright plates 8 not only provide support for the bidirectional threaded rod but also restrict the movement direction of the side clamping plate 22 and the support base plate 32, improving the accuracy and stability of the device.
[0021] like Figure 1 and Figure 3 As shown, in this embodiment, a top-pressing assembly is also installed on the mounting chassis 1. The top-pressing assembly includes a top-pressing mounting bracket 41 fixed to the top of the mounting chassis 1. The top-pressing mounting bracket 41 is inverted U-shaped. An electric push rod 42 is installed at the bottom of the upper end of the top-pressing mounting bracket 41. A top-pressing block 43 for pressing the tailgate of the car is fixed at the telescopic end of the electric push rod 42. Rubber pads are fixed to the top of the supporting base plate 32, the side walls of the two side clamps 22 that are close to each other, and the bottom of the top-pressing block 43.
[0022] The electric push rod 42 can push the top pressure block 43 to move up and down, pressing down on the tailgate placed on the support base plate 32. Working together with the side clamp assembly and support assembly, it achieves all-around fixation of the tailgate. The rubber pads provide cushioning, preventing damage to the tailgate during fixation, while also increasing friction and improving the stability of the fixation.
[0023] like Figure 1 and Figure 2 As shown, in this embodiment, an adjustment assembly for driving the installation chassis 1 to rotate is also provided below the installation chassis 1. The adjustment assembly includes a rotating rod 51 fixed to the bottom of the installation chassis 1. The bottom of the rotating rod 51 is rotatably connected to a main base 52. A reduction motor 53 is installed on the top of the main base 52. The output end of the reduction motor 53 is connected to an output rod 54. Spur gears 55 are fixed on the outer sides of both the output rod 54 and the rotating rod 51. The two spur gears 55 mesh with each other.
[0024] The geared motor 53 drives the rotating rod 51 to rotate through the meshing transmission of the output rod 54 and the spur gear 55, thereby enabling the mounting chassis 1 to adjust its angle according to processing needs. This function facilitates the processing of different angles of the automobile tailgate, improves the flexibility and practicality of the device, and can meet the needs of various complex processing operations.
[0025] The working principle of this utility model is as follows:
[0026] The car tailgate is prepared for processing. Stepper motor B33 starts, driving the bidirectional threaded rod B31 to rotate. Because the bidirectional threaded rod B31 has two sections of external threads with opposite directions, the two support base plates 32 begin to move under the drive of the threads. The support base plates 32 are slidably connected to the top of the mounting platform 6 and to the side uprights 7. This connection method ensures the stability of the support base plates 32 during movement. As the bidirectional threaded rod B31 rotates, the two support base plates 32 move simultaneously towards the center or to the sides, adjusting according to the size of the car tailgate. Once adjusted to the appropriate position, the car tailgate is placed on the support base plates 32. The support base plates 32 provide the main support, and their adjustable design can accommodate tailgates of different sizes, ensuring stable support for tailgates of various dimensions.
[0027] Stepper motor A23 starts, driving bidirectional threaded rod A21 to rotate. The two external threads with opposite directions on bidirectional threaded rod A21 cause the two side clamps 22 to move towards the center simultaneously. The side clamps 22 are positioned between the two mounting plates 6, which are close to each other, clamping the two sides of the car tailgate to achieve lateral clamping of the tailgate.
[0028] The electric push rod 42 at the bottom of the upper end of the top-pressing mounting bracket 41 is activated, pushing the top-pressing block 43 fixed at the telescopic end downward. The rubber pad at the bottom of the top-pressing block 43 contacts the top of the car tailgate, pressing and limiting the tailgate. The rubber pad increases friction, making the pressing more stable, and also prevents damage to the tailgate during the fixing process.
[0029] The adjustment assembly can adjust the angle of the car tailgate as needed. The geared motor 53 on top of the main base 52 starts, driving the output rod 54 to rotate. The spur gear 55 on the outer side of the output rod 54 meshes with the spur gear 55 on the outer side of the rotating rod 51, thereby driving the rotating rod 51 to rotate. The rotating rod 51 is fixed to the bottom of the mounting chassis 1, so the mounting chassis 1 rotates accordingly. The rotation of the mounting chassis 1 drives the entire fixing device and the car tailgate placed on the support base plate 32 to rotate, thereby adjusting the angle of the car tailgate to facilitate processing operations at different angles. For example, when performing welding, drilling, or other processing on certain special parts, adjusting the angle can provide a better processing view and operating space.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
