Description

Technical Field

[0001] This utility model relates to the field of automotive control arm welding technology, specifically an automotive control arm welding support frame. Background Technology

[0002] During the welding process of the car control arm, a support frame is needed to support and fix it.

[0003] Chinese patent CN219254597U discloses a welding fixture for manufacturing automotive control arms. The fixture includes a base with two support frames on its top. Each support frame houses a clamping assembly. The opposing surfaces of the two clamping assemblies are connected to a first clamping seat and a sliding rod, respectively. A second clamping seat is connected to the side of the sliding rod closest to the first clamping seat via a snap-fit ​​shaft. A positioning sleeve is slidably fitted onto the outside of the sliding rod. This patent utilizes the snap-fit ​​shaft to facilitate the rotation of the first and second clamping seats, thereby facilitating the rotation of the control arm after clamping. The engagement of the positioning sleeve and the first connecting sleeve provides a locking effect. Furthermore, the positioning assembly locks the second clamping seat to prevent rotation and ensure stable welding. Simultaneously, releasing the locking of the positioning sleeve and rotating it allows for easy rotation of the control arm to adjust the welding angle.

[0004] In the above technical solution, the first connecting rod moves by injecting air into the air inlet pipe, thereby clamping the control arm. However, external tools are required when injecting air, and the air inlet pipe needs to be blocked after the air is injected to prevent the gas in the fixed sleeve from flowing out. The operation process is quite cumbersome.

[0005] Based on this, the present invention proposes a welding support frame for automotive control arms. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a welding support frame for an automobile control arm. It can drive the connecting rod to move upward through the threaded rod, so that the piston plate moves upward and pushes the two clamping plates to move inward, clamping the control arm. At the same time, it uses the adsorption holes to adsorb the control arm, which achieves a reinforcement effect and improves the practicality of the device.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a welding support frame for an automobile control arm, including a base, two support plates on the base, two fixed sleeves fixedly connected to the two support plates respectively, two piston plates slidably connected to the two fixed sleeves respectively, two connecting columns fixedly connected to the two piston plates respectively, and two clamping plates rotatably connected to the two connecting columns respectively, and further including;

[0009] Preferably, each of the two clamps has two adsorption holes, and each of the two connecting posts has two connecting grooves, which are connected to the two adsorption holes respectively.

[0010] Preferably, two fixed tubes are fixedly connected to each of the two connecting columns, the two fixed tubes are respectively connected to two communicating grooves, and two sliding tubes are slidably connected inside each of the two fixed tubes, and the two sliding tubes are respectively fixedly connected to two fixed cylinders.

[0011] Preferably, each of the two clamping plates has multiple slots, and each of the two connecting columns has two fixed shells fixedly connected to it, with two sliding rods slidably connected inside each of the two fixed shells.

[0012] Preferably, two springs are fixedly connected to each of the two sliding rods, and the two springs are fixedly connected to two fixed housings. Two locking blocks are fixedly connected to each of the two sliding rods, and the locking blocks are adapted to the locking slots.

[0013] Preferably, four limiting rods are fixedly connected to the base, and two support plates are slidably connected to the four limiting rods respectively.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved welding support frame for an automotive control arm. The technical solution of this utility model is as follows:

[0025] like Figures 1-3 As shown, a welding support frame for an automotive control arm includes a base 1, on which two support plates 2 are provided, and two fixing sleeves 3 are fixedly connected to the two support plates 2 respectively. The fixing sleeves 3 have a "U" shaped cross section, and two piston plates 4 are slidably connected inside the two fixing sleeves 3 respectively. Two connecting posts 5 are fixedly connected to the two piston plates 4 respectively. The diameter of the connecting posts 5 is smaller than the diameter of the piston plates 4. Two clamping plates 6 are rotatably connected to the two connecting posts 5 respectively. The frame also includes...

[0026] Two fixed cylinders 11 are fixedly connected to two fixed sleeves 3 respectively. Two transmission pipes 12 are fixedly connected to the two fixed cylinders 11 respectively. The cross-section of the transmission pipes 12 is "L" shaped. The two transmission pipes 12 are fixedly connected to the fixed sleeves 3. Two piston plates 13 are slidably connected to the two fixed cylinders 11 respectively. Two connecting rods 14 are fixedly connected to the two piston plates 13 respectively. Two connecting rings 15 are fixedly connected to the two connecting rods 14 respectively. Two threaded rods 16 are rotatably connected to the two fixed cylinders 11 respectively. The two threaded rods 16 are threadedly connected to the two connecting rings 15 respectively. The threaded rods 16 drive the connecting rings 15 to move upward, so that the connecting rods 14 move upward, which drives the piston plates 13 to move upward, squeezing the air above the fixed cylinders 11 into the fixed sleeves 3. The squeezed air pushes the connecting column 5 to move inward, so that the distance between the two clamping plates 6 becomes smaller, and the two clamping plates 6 clamp the control arm.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, two adsorption holes 7 are respectively opened on the two clamping plates 6, and two connecting grooves 8 are respectively opened on the two connecting columns 5. The cross-section of the connecting groove 8 is "L" shaped, and the two connecting grooves are connected to the two adsorption holes 7 respectively.

[0028] Furthermore, such as Figures 1-3 As shown, two fixed tubes 9 are fixedly connected to the two connecting columns 5 respectively. The two fixed tubes 9 are connected to the two connecting grooves 8 respectively. Two sliding tubes 10 are slidably connected inside the two fixed tubes 9 respectively. The two sliding tubes 10 are fixedly connected to the two fixed cylinders 11 respectively. When the piston plate 13 moves upward, it will draw air into the bottom of the fixed cylinder 11, so that the air enters from the adsorption hole 7 and adsorbs the control arm, which has a reinforcing effect.

[0029] Furthermore, such as Figures 1-3 As shown, multiple slots 17 are provided on the two clamping plates 6 respectively. The slots 17 are arranged in a circular array with the center of the clamping plate 6 as the center. Two fixed shells 18 are fixedly connected to the two connecting columns 5 respectively. The cross-section of the fixed shell 18 is inverted "U" shape. Two sliding rods 19 are slidably connected inside the two fixed shells 18 respectively.

[0030] Furthermore, such as Figure 2 and Figure 3 As shown, two springs 20 are fixedly connected to the two sliding rods 19 respectively. The cross-section of the sliding rod 19 is "L" shaped. The two springs 20 are fixedly connected to the two fixed shells 18 respectively. Two locking blocks 21 are fixedly connected to the two sliding rods 19 respectively. The locking blocks 21 are adapted to the locking slots 17. When the locking blocks 21 are separated from the locking slots 17, the clamping plate 6 can be rotated to drive the control arm to rotate and adjust the angle of the control arm.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, four limiting rods 22 are fixedly connected to the base 1, and two support plates 2 are slidably connected to the four limiting rods 22 respectively. Two adjusting bolts 23 are threaded into the two support plates 2 respectively, and two bevel gears 24 are fixedly connected to the two adjusting bolts 23 respectively. A rotating column 25 is rotatably connected into the base 1, and two bevel gears 26 are fixedly connected to the rotating column 25. The bevel gears 24 and 26 mesh with each other. The height of the support plates 2 is adjusted by adjusting the bolts 23.

[0032] The specific working method is as follows: Place the control arm between the two clamping plates 6, and then rotate the threaded rod 16. Since the connecting ring 15 is threaded onto the threaded rod 16, the connecting ring 15 moves upward with the rotation of the threaded rod 16, causing the connecting rod 14 to move upward. The piston plate 13 moves upward accordingly, squeezing the air above the fixed cylinder 11 into the fixed sleeve 3 through the transmission pipe 12. The squeezed air pushes the connecting column 5 to move inward, making the distance between the two clamping plates 6 smaller. The two clamping plates 6 clamp the control arm. As the piston plate 13 moves upward, it draws air into the bottom of the fixed cylinder 11, allowing the air to enter through the adsorption hole 7 and adsorb the control arm, thus achieving a reinforcement effect and improving the practicality of the device. When it is necessary to adjust the angle of the control arm, push the sliding rod 19 downward, causing the locking block 21 to move downward and move the locking block 21 away from the locking slot 17, releasing the restriction on the clamping plate 6. Then, the clamping plate 6 can be pushed to rotate, causing the control arm to rotate, thereby completing the adjustment of the control arm angle.
