[0002] In the automotive manufacturing industry, the tailgate is a key component of the vehicle body. Its surface pretreatment process directly affects the subsequent coating quality and the corrosion resistance of the entire vehicle. To ensure that the tailgate maintains a stable posture during the pretreatment process, avoids collisions with the treatment tank or other components, and ensures that the treatment liquid can evenly cover the surface of the workpiece, it is necessary to use special tooling to position and support the tailgate.

[0003] A search revealed that Chinese announcement number CN210194019U discloses a flexible tooling for the front treatment of a rear tailgate, belonging to the technical field of automotive design and manufacturing. This utility model's flexible tooling for the front treatment of a rear tailgate includes a rear support frame, a support rod, a positioning block, a rotating connecting rod, and a tooling base. The rear support frame includes a U-shaped support body, with a bottom rod at its bottom end. The upper end of the bottom rod is connected to the upper end of the support rod via a pivot, and the lower end of the bottom rod is connected to one end of the rotating connecting rod via a pivot. The support rod has positioning grooves distributed along its length. The positioning block is installed on the positioning grooves and is fastened to the other end of the rotating connecting rod via a positioning bolt. The lower end of the support rod is fixed to the tooling base. This utility model's flexible tooling for the front treatment of a rear tailgate can adapt to different vehicle structures by adjusting the tooling angle, achieving the purpose of flexible production.

[0004] The aforementioned patent specification mentions that "a receiving space is provided between the first clamping plate and the second clamping plate, and a clamping bolt communicating with the receiving space is provided outside the first clamping plate." In industries such as automobiles, there are various models of tailgates, with differences in size, hole positions, and structure. If the position of the main frame is fixed, flexible tooling cannot accommodate these differences, which may lead to deviations in the positioning and clamping of the tooling and the tailgate, failing to meet the pre-processing requirements of various products. To address the above-mentioned problems, a flexible tooling for tailgate pre-processing is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible tooling for front-end processing of back doors, which solves the problem that some flexible tooling for front-end processing of back doors in the prior art cannot adjust the position of the main frame.

[0007] In this invention, pressing and rotating the card plate separates the sliding card rod and the card slot, allowing the top and bottom sliders to slide; after pulling the pull plate to adjust the position, releasing it causes the installation spring and the return spring to spring back, and the card rod to clamp the card slot for fixation. The operation is simple, the position of the back door can be flexibly adjusted, the spring helps to fix it firmly, adapts to different usage needs, and improves the convenience of adjustment and structural stability.

[0008] In this invention, the back door is placed outside the clamping plate.

[0012] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0013] Reference Figures 1 to 3 This utility model provides an embodiment of a flexible fixture for pre-processing back doors, including a bottom horizontal plate 1, which serves as the basic load-bearing component of the entire fixture, providing a stable sliding track for the bottom sliding blocks 2, and connecting all the upper structures of the fixture into a whole. Bottom sliding blocks 2 are slidably connected to the left and right sides of the bottom horizontal plate 1, driving the mounting vertical plate 3 to adjust its lateral position, thereby changing the lateral span of the fixture to match the dimensions of back doors of different specifications, and providing stable support for the mounting vertical plate 3. The top of the bottom sliding blocks 2 is fixedly connected to the mounting vertical plate 3, connecting the bottom sliding blocks 2 and the top sliding blocks 4, forming a vertical support structure for the fixture, transferring the support force from the bottom to the top, and providing an installation base for the top sliding blocks 4, ensuring that the top sliding blocks 4 can move laterally synchronously with the bottom sliding blocks 2. The top of the mounting vertical plate 3... A top sliding block 4 is fixedly connected. The top sliding block 4 can slide along the length of the top horizontal plate 5 and works in conjunction with the bottom sliding block 2 to adjust the lateral span of the tooling. The top horizontal plate 5 is slidably connected inside the top sliding block 4. The main function of the top horizontal plate 5 is to cooperate with the bottom horizontal plate 1 to form the lateral frame structure of the tooling and provide an installation and support platform for the adaptive installation mechanism 9. An adjustment mechanism 6 is fixedly connected to the top of the top sliding block 4. The adaptive installation mechanism 9 is fixedly connected to the bottom of the top horizontal plate 5. The adaptive installation mechanism 9 includes a connecting frame 91. The main function of the connecting frame 91 is to provide an installation base for other components of the adaptive installation mechanism 9, to firmly connect the entire adaptive installation mechanism 9 to the top horizontal plate 5, and to transmit the supporting force of the top horizontal plate 5. The connecting frame 91 is fixedly connected to the outside of the top horizontal plate 5. A fixed shaft 92 is internally connected to the connecting frame 91. The main function of the fixed shaft 92 is to provide a rotation fulcrum for the rotating plate 93, allowing the rotating plate 93 to rotate around the fixed shaft 92 at a certain angle. This enables the self-adaptive installation mechanism 9 to adjust its angle to accommodate the tilt angle of the back door surface. Multiple rotating plates 93 are externally connected to the fixed shaft 92. The main function of each rotating plate 93 is to drive the connecting shaft 94 and the connecting frame 95 to adjust their position and angle through their own rotation. This allows the damping slider 96 and the clamping plate 97 to adapt to different angles and curvatures of the back door surface, achieving flexible clamping of the back door. A connecting shaft 94 is fixedly connected to the other end of the rotating plate 93. The main function of the connecting shaft 94 is to connect the rotating plate 93 and the connecting frame 95, providing a rotation fulcrum for the connecting frame 95. The connecting frame 95 is rotatably connected to the external of the connecting shaft 94. The main function of the connecting frame 95 is to transmit the motion of the rotating plate 93 and the connecting shaft 94 to the damping slider 96. At the same time, it adjusts the angle of the damping slider 96 by its own rotation, so that the damping slider 96 can maintain good contact with the back door surface. The bottom of the connecting frame 95 is fixedly connected to the damping slider 96. The damping layer buffers the impact force generated during the installation and processing of the back door through elastic deformation, so as to avoid damage to the back door surface. At the same time, through the sliding connection with the clamping plate 97, the bottom of the damping slider 96 is slidably connected to the clamping plate 97. The main function of the clamping plate 97 is to directly contact the back door and achieve clamping and positioning of the back door through cooperation with the damping slider 96. The adjustment mechanism 6 includes a mounting bracket 61. The main function of the mounting bracket 61 is to provide stable mounting support for components such as the connecting shaft 62 and the rotating clamping plate 63, integrating the various components of the adjustment mechanism 6 into a whole, and ensuring that these components can operate stably around a preset trajectory during operation. The mounting bracket 61 is externally fixedly connected to the top of the top sliding block 4, and the connecting shaft 62 is internally fixedly connected to the mounting bracket 61. The main function of the connecting shaft 62 is to serve as the rotation fulcrum of the rotating clamping plate 63, allowing the rotating clamping plate 63 to rotate flexibly around it, thereby realizing the angle adjustment of the adjustment mechanism 6. The rotating clamping plate 63 is rotatably connected to the outside of the connecting shaft 62. The main function of the rotating clamping plate 63 is to drive the telescopic rod 64 and the clamping assembly 66 to move through its own rotation. When the rotating clamping plate 63 rotates... When rotated to the appropriate position, the top sliding block 4 can be fixed by the cooperation of the clamping component 66 and the top horizontal plate 5. At the same time, the telescopic rod 64 and the mounting spring 65 will provide the elastic force for reset or locking. Multiple telescopic rods 64 are fixedly connected to the outside of the rotating plate 63. The main function of the telescopic rods 64 is to limit the rotation range of the rotating plate 63 and prevent its rotation angle from being too large and exceeding the adjustment requirements. The mounting spring 65 is sleeved on the outside of the telescopic rods 64. The main function of the mounting spring 65 is to provide elastic restoring force for the rotating plate 63. When the external force pushes the rotating plate 63 to rotate, the mounting spring 65 stores elastic potential energy. When the external force is removed, the elastic potential energy is released, which drives the rotating plate 63 to automatically reset to the initial position, ensuring that the adjustment mechanism 6 remains stable in the non-working state. The rotating plate 63 has a locking assembly 66 inside, which includes a cavity 661. The main function of the cavity 661 is to provide installation space for the sliding lever 662, the limiting plate 664, and the return spring 665, allowing these components to move smoothly within the cavity 661. At the same time, the size of the cavity 661 limits the range of motion of each component. The cavity 661 is located outside the rotating plate 63. The sliding lever 662 is slidably connected inside the cavity 661. The main function of the sliding lever 662 is to extend downward from the cavity 661 under the elastic force of the return spring 665 and insert into the slot 7 of the top horizontal plate 5, thereby fixing the rotating plate 63 to the top horizontal plate 5 through mechanical locking, thus locking the position of the top sliding block 4. A pull plate 663 is fixedly connected to the top of the sliding lever 662. The main function of the pull plate 663 is to provide convenient operation for the operator. When it is necessary to release the clamping state, the operator can pull the pull plate 663 upwards to drive the sliding rod 662 out of the slot 7 of the top horizontal plate 5. The operation is simple and labor-saving, and it is convenient to quickly adjust the position of the top sliding block 4. The cavity 661 is internally connected to the limit plate 664. The main function of the limit plate 664 is to limit the maximum extension of the sliding rod 662 and prevent it from completely coming out of the cavity 661. At the same time, it provides a force carrier for the return spring 665, so that the elastic force of the return spring 665 can be evenly transmitted to the sliding rod 662 through the limit plate 664. The return spring 665 is sleeved on the outside of the sliding rod 662. When the pull plate 663 is pulled, the return spring 665 is compressed and stores elastic potential energy. After the pull plate 663 is released, the elastic potential energy is released and pushes the sliding rod 662 to clamp again, thereby realizing the automatic reset and continuous clamping function of the clamping component 66. Reference Figures 2 to 4The clamping plate 97 has sliding grooves 98 on both its left and right sides. These grooves provide sliding support for the damping slider 96 and the connecting frame 95, ensuring that they do not shift or wobble when sliding within the grooves 98. They also provide a mounting carrier for the tension spring 910, allowing it to function stably. A fixing rod 99 is fixedly connected inside the grooves 98, and the tension spring 910 is sleeved on the outside of the fixing rod 99. The main function of the tension spring 910 is to provide elastic tension to the damping slider 96. When the damping slider 96 slides along the fixing rod 99 under the pressure of the back door, the tension spring 910 is stretched and stores elastic potential energy. This elastic force keeps the damping slider 96 in close contact with the back door surface. A mounting plate 8 is fixedly connected to the outside of the top sliding block 4, enhancing the overall stability of the fixture and distributing the weight of the bottom horizontal plate 1 and the upper... The load transmitted by the structure is evenly distributed to the ground, avoiding direct contact between the bottom horizontal plate 1 and the ground, which would cause wear or cause the tooling to tilt due to uneven ground. Support seats 10 are fixedly connected to the bottom left and right sides of the bottom of the bottom horizontal plate 1. Multiple slots 7 are opened on the outside of the top horizontal plate 5, which cooperate with the sliding rod 662 to lock the position of the top sliding block 4. When the sliding rod 662 is engaged in different slots 7, the top sliding block 4 can be fixed in the corresponding position, thereby realizing the graded adjustment of the horizontal span of the tooling. The outer bottom end of the sliding rod 662 is locked with the outside of the slot 7. The inside of the damping slider 96 is slidably connected to the outside of the fixed rod 99. The outside of the connecting frame 95 is slidably connected to the outside of the fixed rod 99. One end of the tension spring 910 is fixedly connected to the outside of the damping slider 96, and the other end of the tension spring 910 is fixedly connected to the outside of the slide groove 98.

[0014] Working principle: By pressing and rotating the locking plate 63, the locking plate 63 compresses the telescopic rod 64, which in turn compresses the mounting spring 65 on the outside of the telescopic rod 64. This causes the mounting spring 65 to deform, separating the sliding locking rod 662 from the locking groove 7 on the outside of the top horizontal plate 5. This allows the top sliding block 4 to slide on the outside of the top horizontal plate 5, and the bottom sliding block 2 to slide on the outside of the bottom horizontal plate 1. By pulling the pulling plate 663, the telescopic rod 64 can be further deflected. Pull plate 663 drives limit plate 664 through cavity 661 to press return spring 665, thereby adjusting top sliding block 4 to a suitable position. When the rotating plate 63 is released, the mounting spring 65 rebounds, allowing the rotating plate 63 to rotate. At this moment, the clamping assembly 66 is released, allowing return spring 665 to rebound, thereby locking sliding rod 662 with the slot 7 outside top horizontal plate 5, thus enabling adjustment of the back door position. When fixing the back door, the back door is placed outside the clamping plate 97, which allows the back door to press against the clamping plate 97. This causes the damping slider 96 to deform the tension spring 910 outside the fixing rod 99, which in turn causes the rotating plate 93 outside the connecting shaft 94 to rotate. The back door can then be installed through the clamping plate 97, thus achieving self-adaptive installation of the back door.
