TECHNICAL FIELD

[0001] The utility model relates to casting production technical field, concretely is a kind of casting sandblasting mechanism for reduction gearbox body casting. BACKGROUND

[0002] With the rapid development of manufacturing industry, the production of reduction gearbox body casting is increasing. In the casting production line, the surface of the reduction gearbox body casting will inevitably adhere to impurities such as sand and oxide skin during the casting process. If these impurities are not removed, they will affect the appearance quality of the casting. In some application scenarios of reduction gearbox body with high requirements for surface finish, such as the transmission part of precision machinery, the rough impurities on the surface may cause the wear between parts to increase. Therefore, it is necessary to remove the sand and stones on the surface.

[0003] Chinese utility model patent publication No. CN 220329920 U discloses an automatic sandblasting equipment for precision casting production. The air blower blows air below the air distribution disc. The gas passes through the gap between the vertical cylinder and the cap and is discharged upward. This can blow up the sand in the sandblasting cylinder, making the sand particles boil in the sandblasting cylinder, and facilitating the sanding of the casting wax mold. However, this automatic sandblasting equipment for precision casting production is not convenient for rotating the hanging assembly, making it difficult to clean the casting at multiple angles, resulting in low cleaning efficiency. Moreover, it is not convenient for cleaning multiple castings, further reducing the cleaning efficiency. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a casting sandblasting mechanism for reduction gearbox body casting, which can effectively solve the problem of low cleaning efficiency caused by the difficulty in rotating the hanging assembly and the difficulty in cleaning multiple castings.

[0005] The technical solution adopted by the utility model is a casting sandblasting mechanism for reduction gearbox body casting, which includes a support frame, a reinforcing rod fixedly installed on the outer surface of the support frame, a bottom box fixedly installed on the support frame, a storage box slidingly connected to the inner surface of the bottom box, a limiting groove opened on the inner surface of the storage box, a cleaning box fixedly installed on the other end of the bottom box away from the support frame, a connecting plate fixedly installed on the outer surface of the cleaning box, a rotating column fixedly installed on the inner surface of the connecting plate, a connecting block rotatably installed on the outer surface of the rotating column, a shutter fixedly installed on the other end of the connecting block away from the rotating column, a mounting lock and a control switch arranged on the other side of the shutter away from the cleaning box, a lifting assembly arranged on the inner surface of the cleaning box, and a blowing assembly fixedly installed on the other end of the cleaning box away from the shutter.

[0007] Through the above technical solutions, the positioning column effectively improves the stability of casting placement, the groove facilitates the extraction of the storage box, the combination of the mounting plate and the positioning bolt ensures the accuracy of the working position of the storage box, and the filter plate can initially filter impurities such as sand particles during the cleaning process to prevent them from entering the bottom of the storage box, thus facilitating subsequent cleaning and maintenance.

[0008] Preferably, an inclined plate is fixedly installed on the inner surface of the cleaning box, and the inclined plate is located directly above the center line of the filter plate.

[0009] With the above technical solution, during sand blowing operations, the sand particles and other impurities blown off will slide down the inclined plate onto the filter plate.

[0032] Specifically, an inclined plate 10 is fixedly installed on the inner surface of the cleaning box 11. The inclined plate 10 is located directly above the center line of the filter plate 20. The advantage is that during sand blowing operations, the sand particles and other impurities blown off will slide down the inclined plate 10 onto the filter plate 20.

The hanger 1806 can share the weight of the casting, making the hoisting more stable, while the limiting hook 1808 can prevent the casting from shaking or shifting during hoisting and cleaning, ensuring the safety of the operation. At the same time, it is also conducive to the all-round sandblasting cleaning of the casting, improving the cleaning quality, and increasing the storage capacity of the overall mechanism.

[0036] Specifically, the air blowing assembly 19 includes an air pump 1901. One end of the air pump 1901 is provided with an air inlet pipe 1902, and the other end of the air pump 1901 away from the air inlet pipe 1902 is provided with an air delivery pipe 1903. The outer surface of the air delivery pipe 1903 is provided with a limiting ring 1906 adapted to the cleaning box 11. The advantage is that when the air pump 1901 is started, air enters the air pump 1901 through the air inlet pipe 1902, and is then delivered to the cleaning box 11 through the air delivery pipe 1903. When installing the air supply pipe 1903, the air supply pipe 1903 is fixed in a suitable position on the cleaning box 11 by the limiting ring 1906. The air pump 1901 can provide a stable airflow for sand blowing operations, the air inlet pipe 1902 ensures the supply of air source, and the limiting ring 1906 fixes the position of the air supply pipe 1903 in the cleaning box 11 to prevent it from shaking or shifting under the impact of airflow, thus ensuring the stability and reliability of the air blowing operation and making the sand blowing effect more uniform.

[0037] Specifically, the outer surface of the air supply pipe 1903 is provided with multiple air outlet pipes 1904 and nozzles 1905. The air outlet pipes 1904 and nozzles 1905 are a group and are located inside the cleaning box 11.

[0038] Working principle: During use, the casting is placed in the storage box 4 and stabilized by the positioning pin 6 to prevent shaking. When cleaning is required, the storage box 4 is pulled out through the pull groove 7. The mounting plate 8 and positioning bolt 9 ensure the accuracy of the position when pulling out and putting back. Then, the motor 1801 in the hoisting assembly 18 is started. The motor 1801 drives the connecting rod 1802 to rotate, so that the hook 1803 rotates to the appropriate position. The lifting ring 1804 on the casting is connected to the hook 1803. The hanger 1806 on the fixing rod 1805 supports the weight of the casting. The limiting hook 1808 of the mounting ring 1807 limits and fixes the casting. Then, the casting is hoisted into the cleaning box 11. After that, the air pump 1901 of the air blowing assembly 19 is started. Air enters the air pump 1901 through the air inlet pipe 1902 and is then delivered to the cleaning box 11 through the air delivery pipe 1903. The air delivery pipe 1903 is fixed in position by the limiting ring 1906 to prevent shaking. Airflow is ejected from multiple outlet pipes 1904 and nozzles 1905 on the air supply pipe 1903, acting on the casting surface at multiple angles to perform sandblasting cleaning. During the sandblasting process, the blown-off sand particles and other impurities slide down the inclined plate 10 inside the cleaning box 11 onto the filter plate 20 in the limiting groove 5 of the storage box 4. The filter plate 20 performs preliminary filtration of impurities, preventing them from entering the bottom of the storage box 4, facilitating subsequent cleaning and maintenance. The inclined plate 10 also improves the cleaning efficiency inside the cleaning box 11, reduces impurity residue, ensures a clean internal environment, and minimizes the impact on subsequent operations.
