Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a support fixture for automotive tailgates used in vehicle painting. Background Technology

[0002] In vehicle painting processes, the support fixture for the tailgate is crucial for ensuring the painting effect. However, existing support fixtures are insufficient in adapting to tailgate sizes. Traditional support fixtures are usually designed in a fixed manner, and the clamping distance is difficult to adjust flexibly. Faced with different tailgate widths for different car models and styles, the fixed-distance fixtures cannot meet the requirements. In actual painting operations, frequent fixture changes not only consume a lot of time but also lead to low production efficiency. Moreover, tailgate instability due to incompatible fixtures often occurs, which can cause the tailgate to shake during the painting process, thus affecting the painting quality, causing uneven coating and other problems, and increasing rework costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a support fixture for automobile tailgates used in vehicle painting. After the servo motor of the adjustment device is started, it drives the worm gear and worm wheel to rotate, causing the bidirectional screw to rotate and drive the internal thread plate to slide, easily realizing the flexible change of the clamping distance. This allows it to adapt to automobile tailgates of different widths, improving the versatility of the fixture, effectively reducing the frequency of fixture replacement, and meeting diverse production needs.

The servo motor of the adjusting device drives the worm gear and worm wheel to rotate the bidirectional screw, which drives the internal thread plate to slide, thus flexibly changing the clamping distance. This can drive the clamping device to move, adapt to different widths of car tailgates, improve the versatility of tooling, and reduce the frequency of tooling changes.

[0019] 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.

[0020] Please see Figure 1-4This utility model provides a technical solution: a support fixture for a car tailgate used in vehicle painting, including a fixed base 1, and further including: an adjusting device 2, the outer wall of which is fixedly connected to the inner wall of the fixed base 1; a clamping device 3, the outer wall of which is slidably connected to the inner wall of the fixed base 1; the adjusting device 2 includes a servo motor 21, the output end of which is fixedly connected to a worm gear 22, a positioning frame 23 symmetrically arranged on the outside of the worm gear 22, a worm wheel 24 rotatably connected to the outer wall of the positioning frame 23, a bidirectional screw 25 fixedly connected to the inner wall of the worm wheel 24, and an internal thread plate 26 symmetrically threaded to the outer wall of the bidirectional screw 25; the servo motor 21 is fixed inside the fixed base 1. After the wall is started, its output end drives the worm 22 to rotate. The worm 22 meshes with the worm wheel 24. Due to the rotation of the worm 22, the worm wheels 24 on the two side positioning frames 23 rotate synchronously. The rotation of the worm wheels 24 causes the bidirectional screw 25, which is fixedly connected to its inner wall, to rotate as well. The bidirectional screw 25 can rotate stably under the support of the positioning frame 23. The internal thread plates 26 with symmetrical threaded connections on their outer walls will slide in opposite directions along the inner wall of the fixed seat 1 under the action of the threads, depending on the rotation direction of the bidirectional screw 25. In this way, the distance between the two internal thread plates 26 can be adjusted, thereby driving the clamping device 3 to move and changing the interval between the clamping devices 3.

[0021] The outer wall of the servo motor 21 is fixedly connected to the inner wall of the fixed base 1, the outer wall of the positioning frame 23 is fixedly connected to the inner wall of the fixed base 1, the outer wall of the bottom of the internal thread plate 26 is slidably connected to the inner wall of the fixed base 1, the outer wall of the worm 22 meshes with the outer wall of the worm wheel 24, and the outer wall of the bidirectional screw 25 is rotatably connected to the inner wall of the positioning frame 23.

[0022] The clamping device 3 includes a movable block 31. A damping rod 32 is fixedly connected to the outer wall of the movable block 31. A compression spring 33 is sleeved on the outside of the damping rod 32. A blocking frame 34 is fixedly connected to the end of the damping rod 32 away from the movable block 31. A connecting rod 35 is symmetrically rotatably connected to the outer wall of the blocking frame 34. A pressure plate 36 is rotatably connected to the end of the connecting rod 35 away from the blocking frame 34. A telescopic rod 37 is fixedly connected to the outer wall of the bottom of the pressure plate 36. A compression spring 38 is sleeved on the outside of the telescopic rod 37. A sliding plate 39 is fixedly connected to the outer wall of the bottom of the telescopic rod 37. The outer wall of the movable block 31 is connected to the damping rod 32, and the compression spring 33 is sleeved on the damping rod 32. The end is connected to the blocking frame 34. When the movable block 31 moves, it will drive the blocking frame 34 to move synchronously, which can be adjusted according to the width of the tailgate. The blocking frame 34 is rotatably connected to the pressure plate 36 through the connecting rod 35. The bottom of the pressure plate 36 is connected to the sliding plate 39 through the telescopic rod 37 and the compression spring 38. The sliding plate 39 slides on the outer wall of the fixed seat 1. Before the tailgate is placed in the support position of the tooling, the movement of the movable block 31 is roughly adjusted according to the width of the tailgate so that the blocking frame 34 is as close to the tailgate as possible. At this time, the tailgate is placed on the pressure plate 36. Due to gravity, the pressure plate 36 moves downward. The connecting rod 35 rotates due to the movement of the pressure plate 36.

[0023] The outer wall of the movable block 31 is slidably connected to the inner wall of the fixed seat 1, the outer wall of the movable block 31 is fixedly connected to the outer wall of the internal thread plate 26, the inner wall of the movable block 31 is slidably connected to the outer wall of the bidirectional screw 25, the outer wall of the bottom of the sliding plate 39 is slidably connected to the outer wall of the fixed seat 1, the outer wall of the movable block 31 is slidably connected to the inner wall of the blocking frame 34, one end of the compression spring 33 is fixedly connected to the outer wall of the movable block 31, the other end of the compression spring 33 is fixedly connected to the outer wall of the blocking frame 34, the top end of the compression spring 38 is fixedly connected to the outer wall of the bottom of the pressure plate 36, the outer wall of the bottom of the compression spring 38 is fixedly connected to the outer wall of the top of the sliding plate 39. At this time, the blocking frame 34 will move closer to the movable block 31 under the rotation of the connecting rod 35. The damping rod 32 and the compression spring 33 are both compressed at this time. The blocking frames 34 on both sides clamp the tailgate and complete the initial clamping. At this time, the final fixation is completed again by the adjustment device 2.

[0024] When in use, the support fixture for the tailgate of the vehicle painting consists of a fixed base 1, an adjusting device 2, and a clamping device 3 working together to provide stable and reliable support for the tailgate during the painting process. The fixed base 1 serves as the basic support structure of the entire fixture and provides an installation platform for the adjusting device 2 and the clamping device 3, ensuring the stability of the fixture during use.

[0025] The adjustment device 2 is mainly used to adjust the support position of the tooling to adapt to different sizes and shapes of car tailgates. The servo motor 21 is fixed on the inner wall of the fixed base 1. After starting, its output end drives the worm 22 to rotate. The worm 22 meshes with the worm wheel 24. Due to the rotation of the worm 22, the worm wheels 24 on the two side positioning frames 23 rotate synchronously. The rotation of the worm wheel 24 causes the bidirectional screw 25, which is fixedly connected to its inner wall, to rotate as well. The bidirectional screw 25 can rotate stably under the support of the positioning frame 23. The internal thread plate 26 with symmetrical threaded connection on its outer wall will slide in opposite directions or in opposite directions along the inner wall of the fixed base 1 under the action of the thread, according to the rotation direction of the bidirectional screw 25. In this way, the distance between the two internal thread plates 26 can be adjusted, thereby driving the clamping device 3 to move, so that the interval between the clamping devices 3 changes, thereby meeting the support requirements of different car tailgate widths and improving the versatility and adaptability of the tooling.

[0026] The clamping device 3 is used to clamp both ends of the car tailgate, initially clamping it to prevent it from shaking when the tailgate is placed, and ensuring that it is difficult to move during the painting process. The movable block 31 is fixedly connected to the internal thread plate 26, and also slidably connected to the bidirectional screw 25, so that the movable block 31 can move with the movement of the internal thread plate 26. The outer wall of the movable block 31 is connected to the damping rod 32, and the damping rod 32 is fitted with a compression spring 33. The other end is connected to the blocking frame 34. When the movable block 31 moves, it will drive the blocking frame 34 to move synchronously, which can be adjusted according to the width of the tailgate. The blocking frame 34 is rotatably connected to the pressure plate 36 through the connecting rod 35. The bottom of the pressure plate 36 is connected to the sliding plate 39 through the telescopic rod 37 and the compression spring 38. The sliding plate 39 slides on the outer wall of the fixed seat 1. Before the tailgate is placed in the support position of the tooling, the movement of the movable block 31 is roughly adjusted according to the width of the tailgate so that the blocking frame 34 can move as far as possible. The tailgate is positioned close to the pressure plate 36. Due to gravity, the pressure plate 36 moves downward. The connecting rod 35 rotates in response to the movement of the pressure plate 36, and the compression spring 38 and telescopic rod 37 are compressed. After the tailgate is removed, the pressure plate 36 can be lifted again by the compression spring 38 for easy clamping next time. At this time, the blocking frame 34 will move closer to the movable block 31 under the rotation of the connecting rod 35. The damping rod 32 and the compression spring 33 are compressed. The blocking frames 34 on both sides clamp the tailgate, completing the initial clamping. The final fixation is then completed by the adjustment device 2. The compression spring 33 and the damping rod 32 prevent damage to the tailgate due to excessive clamping force during the initial clamping. The entire clamping device 3 can adaptively adjust according to the shape and position of the tailgate and provide a stable and reliable clamping force to ensure the stability of the tailgate during the painting process and improve the painting quality.
