Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a rust removal device for processing automotive parts. Background Technology

[0002] Currently, the most common rust removal methods on the market include polishing and pickling. While polishing can remove surface rust, its effectiveness against deep-seated rust is limited, and the process is complex and costly. Pickling, on the other hand, is widely used due to its efficient and thorough rust removal effect.

[0003] However, traditional pickling for rust removal presents numerous inconveniences in practice. For example, during pickling, workers need to move parts from the processing area to racks for rust removal, and then remove them and place them in drain baskets to dry. This process not only increases the labor intensity of workers but may also cause secondary damage to the parts during handling, affecting their precision and quality. Furthermore, frequent handling reduces the efficiency of rust removal and increases production costs.

[0004] Therefore, it is necessary to propose a rust removal device for automotive parts processing to improve the efficiency and quality of rust removal work and meet the needs of the automotive parts processing industry. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Reference Figure 1 This utility model provides a rust removal device for processing automotive parts, including a frame 1, with a conveying mechanism 2 and a rust removal tank 3 installed inside the frame 1; the rust removal tank 3 is located below the conveying mechanism 2, and a platform 4 is provided at both ends of the frame 1 for placing the parts to be rusted and the parts that have been processed.

[0019] The conveying mechanism 2 is equipped with a hanging frame 5, which automatically clamps the parts placed on the platform 4. The conveying mechanism 2 can automatically transfer the hanging frame 5 from the platform 4 on one side of the frame 1 to the other side, and during the transfer process, the parts are immersed in the rust removal tank 3 for rust removal treatment. This design not only avoids the tediousness of manual handling, but also greatly improves the rust removal efficiency.

[0020] Reference Figure 2 The conveying mechanism 2 includes a lifting frame 202, a translation frame 203, and a lifting mechanism 206. The lifting frame 202 is slidably connected to the guide rod 201 inside the frame 1 and is driven by the lifting mechanism 206 to achieve reciprocating lifting motion. The translation frame 203 is slidably connected to the lifting frame 202. A translation motor 204 is installed on the lifting frame 202, and a rack 205 that cooperates with the output shaft of the translation motor 204 is installed on the translation frame 203 to achieve horizontal movement. Hooks 207 are provided on the translation frame 203, which cooperate with the hanging frame 5. When the translation frame 203 rises after descending to the lowest point with the lifting frame 202, it hooks the hanging frame 5, thereby driving it to move accordingly.

[0021] The rust removal tank 3 consists of two parts: an acid pickling tank 301 and a clean water tank 302. The acid pickling tank 301 is used to perform acid pickling and rust removal treatment on the parts; while the clean water tank 302 is used to clean the residual acid on the surface of the parts. To ensure the stable movement and positioning of the hanger 5 in the rust removal tank, both the acid pickling tank 301 and the clean water tank 302 are provided with slots 301 that cooperate with the hanger 5.

[0022] Reference Figure 3The bracket 5 consists of a horizontal bar 501 and two vertical bars 502. The vertical bars 502 are symmetrically arranged around the center of the horizontal bar 501. A lifting support rod 503 is provided below the vertical bars 502. A slip ring 504 is slidably installed on the vertical bars 502. A side support rod 505 is installed on the slip ring 504 and fixedly connected to both ends of the lifting support rod 503, so that the lifting support rod 503 is kept perpendicular to the vertical bar 502. The lifting support rod 503 is provided with a clamping groove 507 and a clamping rod 508. There are two clamping grooves 507 symmetrically arranged around the center of the lifting support rod 503. The two ends of the clamping rod 508 are slidably installed in the clamping grooves 507 of the two lifting support rods 503 respectively. In addition, a pull rod 512 is provided at the lower end of the vertical bar 502. One end of the pull rod 512 is connected to the vertical bar 502 by a hinge, and the other end is connected to the clamping rod 508.

[0023] During operation, the car parts are placed on the storage platform 4. The operator holds two sliding rings 504. Under the action of gravity, the vertical rod 502 moves downward within the sliding rings 504, while the two clamping rods 508 are separated to the sides. The operator passes the car parts through the two clamping rods 508 and places the hanger 5 on the storage platform 4.

[0024] When the translation frame 203 rises after descending to the lowest point with the lifting frame 202, it hooks the horizontal bar 501; as the vertical bar 502 rises, the two clamping bars 508 move closer to the middle, thereby realizing automatic clamping of the automotive parts, and entering the rust removal tank 3 through the conveying mechanism 2 for rust removal operation.

[0025] To further improve the stability and durability of the hanger 5, the structure of the pull rod 512 has been optimized. The pull rod 512 consists of two hollow tubes, which are respectively connected to the clamping rod 508 and the vertical rod 502. Between the hollow tubes, a connecting rod 512 and a tension spring 513 are provided. The two ends of the tension spring 513 are respectively connected to the two hollow tubes, providing a certain elastic restoring force for the pull rod 512. When the hanger 5 is subjected to impact or vibration during transportation, the buffer tension spring 513 can absorb some energy, reduce the impact on the accessories, and prevent them from falling off the hanger 5.

[0026] To ensure that the two clamping rods 508 remain far apart in their natural state, the lower part of the vertical rod 502 is designed as a hollow structure with a radial through groove 509. A return spring 510 and a limiting rod 511 are installed inside the lower part of the vertical rod 502. One end of the return spring 510 is connected to the vertical rod 502, and the other end is connected to the limiting rod 511. The limiting rod 511 is positioned between the slip ring 504 and the lower end of the vertical rod 502. The return spring 510, through its elastic force, pushes the slip ring 504 upwards along the through groove 509 of the vertical rod 502, thereby causing the clamping rods 508 to open. When the hanger 5 is hung up, the return spring 510 is stretched. When the hanger 5 is returned to the shelf 4, the return spring 510 releases energy, automatically opening the clamping rods 508.

[0027] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
