Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting machines for air spring production, specifically an automatic sandblasting machine for air spring production. Background Technology

[0002] Sandblasting machines are surface treatment equipment widely used in industrial production. Their core function is to clean, strengthen, or beautify the surface of workpieces by high-speed jetting of abrasive. In the production of air springs, sandblasting machines can pre-treat the surface of the air springs, ensuring not only the uniformity and consistency of the sandblasting process and improving product quality, but also keeping the surface of the air springs intact and uncontaminated, thus improving the protection of the air springs. After sandblasting the surface of the air springs, residual abrasive will fall to the bottom of the machine frame. If the residual abrasive and the debris that falls off the surface of the air springs cannot be effectively separated, workers will have to spend a lot of time separating the residual abrasive and air spring debris, increasing the downtime of the equipment, reducing the efficiency of the sandblasting equipment, and thus affecting the overall production progress.

[0003] To overcome the above-mentioned defects, the existing technology (Chinese patent application number CN202021358468.5, application date 2021-03-30) sand and gravel screening device includes a support platform, a screening outer cylinder on the support platform, and a screening inner cylinder rotatably connected inside the screening outer cylinder. An annular cavity for accommodating sand and gravel is formed between the screening inner cylinder and the screening outer cylinder. One end of the screening inner cylinder is opened as a feed inlet, and the other end is opened as a first discharge outlet. The end of the screening outer cylinder near the first discharge outlet is opened as a second discharge outlet. The end of the screening inner cylinder near the first discharge outlet extends to the outside of the screening outer cylinder. Screening holes are provided on the side wall of the screening inner cylinder inside the screening outer cylinder. Two collection pools are provided on one side of the support platform, located below the first and second discharge outlets respectively. This device can efficiently screen sand and gravel and has energy-saving and environmentally friendly functions.

[0004] Air springs have complex structures with many irregular curved surfaces, corners, and edges. The oscillating sandblasting components can flexibly change the sandblasting angle and position, allowing the sand to evenly cover all surfaces of the air spring and avoiding sandblasting dead zones. However, the aforementioned device cannot evenly sandblast the air spring during use, resulting in uneven sand coverage on the air spring surface, affecting the overall quality consistency of the air spring, and also causing impurities to remain on the air spring surface, affecting the performance and service life of the air spring. Utility Model Content

It also makes the sandblasting force and abrasive distribution on the air spring surface more uniform.

[0015] Furthermore, this ensures the consistency of the sandblasting effect on the air spring surface, improves the overall quality of the product, and enhances the continuity and efficiency of the sandblasting operation.

Detailed Implementation

[0027] 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.

[0028] Example 1: By using the frame 1, support plate 5, and limiting rod 18, shaking during operation is prevented, thus improving the stability of the device. Figures 1-3 As shown: It includes a frame 1, a sand box 4 is fixedly connected to the upper rear side of the frame 1, a discharge port 2 is fixedly connected to the lower surface of the frame 1, and a separation box 3 is fixedly connected to the bottom of the frame 1. At the same time, a support plate 5 is fixedly connected to the upper left side of the frame 1. A rotating shaft 7 is rotatably installed inside the frame 1, and a drive shaft 9 is rotatably installed inside the frame 1. A sandblasting assembly 13 is fixedly connected to the surface of the drive shaft 9. The sandblasting assembly 13 is rotatably installed inside the frame 1. A baffle 17 is fixedly connected to the upper surface of the separation box 3, and a limit rod 18 is fixedly connected to the lower surface of the baffle 17. The limit rod 18 is symmetrically distributed about the center of the separation box 3. A screen plate 19 is slidably connected through the limit rod 18. A fixing plate 20 is fixedly connected to the inner wall of the separation box 3.

[0029] According to the process requirements of the air spring, the staff selects appropriate sandblasting material and injects it into the sand box 4. At the same time, they ensure that the sand material inside the sand box 4 can support the stable operation of the sandblasting component 13. The staff also places the air spring stably inside the frame 1 and securely clamps it with special fixtures to ensure that the air spring will not shift or shake during the sandblasting process, thus ensuring sandblasting accuracy. Then, the staff starts the device, and the sand material inside the sand box 4 is transported to the sandblasting component 13 through the pipeline, thereby realizing the sandblasting treatment of the air spring. The support plate 5 and the limit rod 18 set up reduce the shaking generated during the operation of the device, ensuring that the device can operate stably. At the same time, the sandblasting component 13 can accurately spray the air spring surface, improving the overall quality of the air spring.

[0030] In Example 2, unlike Example 1, the rack 12, gear 8, and gear 10 are configured to effectively cover the air spring, thus improving the overall sandblasting quality of the device. Figures 4-5 As shown: A motor 6 is fixedly connected to the upper surface of the support plate 5, and a rotating shaft 7 is fixedly connected to the output end of the motor 6. A first gear 8 is fixedly connected to the surface of the rotating shaft 7. A recess 11 is fixedly connected to the upper surface of the support plate 5 near the first gear 8, and a rack 12 is slidably connected to the surface of the recess 11. The rack 12 and the first gear 8 are meshed together. A second gear 10 is fixedly connected to the surface of the transmission shaft 9 near the rack 12. The second gear 10 and the rack 12 are meshed together. The second gear 10 and the first gear 8 are also meshed together. Both the first gear 8 and the second gear 10 are half-gear structures.

[0031] When the motor 6 rotates, it drives the output shaft 7 to rotate inside the frame 1. The first gear 8 on the surface of the shaft 7 meshes with the rack 12, causing the rack 12 to slide on the surface of the concave block 11. This causes the rack 12 to mesh with the second gear 10 on the surface of the transmission shaft 9, thereby causing the transmission shaft 9 to reciprocate inside the frame 1. This drives the sandblasting assembly 13 to swing inside the frame 1, increasing the sandblasting range and ensuring that all surfaces of the air spring receive uniform sandblasting treatment. It also makes the sandblasting force and abrasive distribution on the surface of the air spring more uniform, ensuring the consistency of the sandblasting effect on the surface of the air spring, improving the overall quality of the product, and enhancing the continuity and efficiency of the sandblasting operation.

[0032] In Example 3, unlike Example 2, the sieve plate 19, connecting rod 16, and fixing column 21 enable the device to complete the screening and recycling of a large amount of sand in a shorter time, thereby improving overall production efficiency. Figures 6-7 As shown: A fixed block 14 is fixedly connected to one end of the upper surface of the separation box 3 near the support plate 5, and a movable shaft 15 is rotatably installed inside the fixed block 14. Both the surface of the movable shaft 15 and the surface of the rotating shaft 7 are fitted with belts. A connecting rod 16 is fixedly connected to the surface of the movable shaft 15, and the connecting rods 16 are symmetrically distributed about the center of the movable shaft 15. The ends of the connecting rods 16 are all arc-shaped. A fixed column 21 is fixedly connected to the surface of the sieve plate 19, and one end of a buffer spring 22 is fixedly connected to the lower surface of the fixed column 21. The other end of the buffer spring 22 is fixedly connected to a fixed plate 20. The top of the fixed column 21 is arc-shaped.

[0033] When the motor 6 is working via a belt, it drives the moving shaft 15 to rotate inside the fixed block 14. At the same time, the connecting rod 16 on the surface of the moving shaft 15 rotates on the upper surface of the separation box 3. When the connecting rod 16 contacts the fixed column 21, the connecting rod 16 pushes the fixed column 21, causing the screen plate 19 to slide on the surface of the limit rod 18. At the same time, the buffer spring 22 retracts towards the surface of the fixed plate 20, causing the screen plate 19 to vibrate inside the separation box 3. This not only enables the screening and recycling of sand, but also ensures a sufficient supply of qualified sand during continuous operation of the automatic sandblasting machine, reducing production stoppages caused by untimely sand supply and improving overall production efficiency.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
