Technical Field

[0001] This utility model relates to the technical field of stabilizer bar processing, and in particular to a stabilizer bar hot shot blasting fixture. Background Technology

[0002] Stabilizer bars, through their torsional characteristics, generate an opposing torque to counteract body roll when a vehicle tilts, thereby improving handling stability and ride comfort. As a crucial component of the automotive suspension system, the fatigue life of the stabilizer bar directly impacts vehicle handling stability and safety. While traditional cold shot blasting can improve the surface strength of stabilizer bars, it suffers from issues such as shallow residual compressive stress layers and stress concentration, making it difficult to meet the increasingly demanding performance requirements of automobiles. Hot shot blasting fixtures for stabilizer bars are suspension devices specifically designed for the hot shot blasting reinforcement process of automotive stabilizer bars; therefore, a special type of hot shot blasting fixture for stabilizer bars is needed.

[0003] However, most of the existing stabilizer bar shot blasting fixtures have fixed dimensions. When the stabilizer bar size is different, different fixtures need to be replaced to hang the stabilizer bar, which is cumbersome and increases costs. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 stabilizer bar hot shot blasting fixture, including an upper support frame 1, a lower support frame 2 and an adjustment mechanism 3. The upper support frame 1 is vertically connected to the lower support frame 2 through a slidable connection structure. An adjustment mechanism 3 is provided on one side of the surface of the upper support frame 1. A crossbeam 4 is fixedly connected to the middle of the top of the upper support frame 1. A hook 5 is fixedly connected to the middle of the crossbeam 4. One end of the hook 5 is connected to a hanger 6.

[0021] The adjustment mechanism 3 includes a mounting groove 301, a sliding groove 302 on the top of the lower support frame 2, a limiting hole 303 on one side of the surface of the lower support frame 2, and a return spring 304 inside the mounting groove 301. One end of the return spring 304 is fixedly connected to a limiting block 305. Through the arrangement of the mounting groove 301, sliding groove 302, limiting hole 303, return spring 304, and limiting block 305, during use, when it is necessary to adjust the distance between the upper support frame 1 and the lower support frame 2 according to different sized stabilizer bars, the limiting block 305 can be pressed, causing it to move inwards into the mounting groove 301. Since the return spring 304 is located inside the mounting groove 301 and one end is fixedly connected to the limiting block 305, when the limiting block 305 moves inwards into the mounting groove 301... When the return spring 304 is compressed and deformed, and the limiting block 305 is fully engaged in the mounting groove 301, the limiting block 305 loses its limiting function on the upper support frame 1. Since the upper support frame 1 is slidably connected to the lower support frame 2 through the sliding groove 302, the upper support frame 1 can slide up and down inside the sliding groove 302. The upper support frame 1 can be slid to a suitable position as needed, and the mounting groove 301 is aligned with a set of limiting holes 303. At this time, the return spring 304 rebounds and deforms based on its characteristics. The rebounding return spring 304 drives the limiting block 305 to return to its original relative position. At this time, one end of the limiting block 305 is engaged in the mounting groove 301, and the other end of the limiting block 305 is engaged in the limiting hole 303, thereby limiting and fixing the upper support frame 1.

[0022] Furthermore, the bottom of the upper support frame 1 is fitted inside the slide groove 302. Through the setting of the slide groove 302, the upper support frame 1 can slide up and down above the lower support frame 2 through the slide groove 302 during use. The slide groove 302 and the limiting mechanism form a "dynamic adjustment + static locking" dual-mode system, which not only meets the flexible adjustment requirements, but also ensures the structural rigidity under high load conditions, directly improving the surface strengthening quality of the stabilizer bar.

[0023] Furthermore, eight sets of limiting holes 303 are provided, and the limiting holes 303 are evenly distributed. Through the setting of the limiting holes 303, a mechanical self-locking system is formed between the limiting holes 303 and the limiting blocks 305 during use. The small-diameter end of the stepped limiting block 305 transitions with the hole position to achieve rigid fixation at a preset height. In high-vibration scenarios such as shot blasting and bending, the inner surface of the limiting holes 303 is hardened, and the hardened layer absorbs high-frequency impact energy. Simultaneously, the rebound force of the return spring 304 buffers vibration transmission, preventing the mechanism from failing due to long-term impact. Through the equidistant distribution design, the limiting holes 303 provide standardized adjustment levels. Operators can quickly select the positioning point matching the working conditions, improving adjustment efficiency and reducing human error.

[0024] Furthermore, one end of the return spring 304 is fixedly connected to the upper support frame 1 inside the mounting groove 301. Through the arrangement of the return spring 304, energy is stored through elastic deformation during use, providing a rebound force after the external load disappears, driving the limit block 305 to automatically return to its initial position, ensuring the positioning accuracy of repeated actions. In the stabilizer bar hanger, this spring causes the limit block 305 to engage instantly with the limit hole 303, maintaining the stability of the suspension height.

[0025] Furthermore, one end of the limiting block 305 is fitted inside the mounting groove 301, and the other end of the limiting block 305 is fitted inside the limiting hole 303. The limiting block 305 is a stepped cylinder, with its large-diameter end in clearance fit with the mounting groove 301 and its small-diameter end in transition fit with the limiting hole 303. Through the setting of the limiting block 305, the cooperation between the limiting block 305 and the limiting hole 303 during use can precisely adjust the sliding stroke of the upper support frame 1, ensuring the positioning accuracy of the stabilizer during the hot shot blasting process. The stepped cylindrical design of the limiting block 305 is embedded into the limiting hole 303 by the elastic force of the return spring 304, forming a mechanical self-locking mechanism to prevent the hanger from being accidentally displaced due to vibration or load.

[0026] Furthermore, a detachable counterweight 7 is bolted to the bottom of the hanger 6. The counterweight 7 is made of ZG270-500 cast steel. Through the setting of the counterweight 7, the detachable design of the bolt fixation allows the counterweight 7 to accurately adjust the center of gravity position of the hanger 6 during use, ensuring that the stabilizer maintains dynamic balance during the high-speed rotation of the hot shot blasting, and avoiding vibration or displacement caused by uneven mass distribution. The high density of the ZG270-500 cast steel material can effectively offset the impact force generated during the operation of the shot blasting machine, preventing the hanger from structural deformation or displacement due to instantaneous load.

[0027] Furthermore, both the upper support frame 1 and the lower support frame 2 are made of Q355B low alloy steel and have been hot-dip galvanized. Through the arrangement of the upper support frame 1 and the lower support frame 2, the vertically connected sliding structure ensures that the fixture maintains overall rigidity under the high-speed impact of hot shot blasting. The crossbeam 4 at the top of the upper support frame 1 and the load-bearing hook 5 constitute the main load-bearing system. The lower support frame 2 disperses the dynamic load through the bottom guide rail, avoiding deformation caused by stress concentration. Through the cooperation of the sliding groove 302 and the limiting hole 303, the upper support frame 1 and the lower support frame 2 can be adjusted bidirectionally to adapt to the shot blasting operation requirements of different specifications of stabilizer bars. The adjustment accuracy is ensured by the stepped structure of the limiting block 305. The Q355B low alloy steel material and hot-dip galvanizing treatment enhance impact resistance. The split design of the upper support frame 1 and the lower support frame 2 allows for independent replacement of worn parts, reducing maintenance costs.

[0028] Working principle: First, adjust the upper support frame 1 and lower support frame 2 according to the size of the stabilizer bar. Press the limiting block 305, and the limiting block 305 moves into the mounting groove 301. Since the return spring 304 is located inside the mounting groove 301 and one end is fixedly connected to the limiting block 305, the return spring 304 is compressed and deformed when the limiting block 305 moves into the mounting groove 301. When the limiting block 305 is fully engaged inside the mounting groove 301, the limiting block 305 loses its limiting function on the upper support frame 1. Since the upper support frame 1 is slidably connected to the lower support frame 2 through the sliding groove 302, the upper support frame 1 can move inside the sliding groove 302. Slide the upper support frame 1 up and down as needed to make the mounting groove 301 aligned with a set of limiting holes 303. At this time, the return spring 304 will rebound and deform according to its characteristics. The rebounding return spring 304 will drive the limiting block 305 to return to its original relative position. At this time, one end of the limiting block 305 is fitted into the inside of the mounting groove 301, and the other end of the limiting block 305 is fitted into the inside of the limiting hole 303. Thus, the limiting block 305 limits and fixes the upper support frame 1. Place the stabilizer on the hanger 6, and then place it between the upper support frame 1 and the lower support frame 2 through the hook 5. Finally, fix the counterweight 7 in a suitable position.
