Description

Technical Field

[0001] The utility model belongs to the technical field of aviation accessories, and particularly relates to a dust removal device for producing aviation and aerospace vehicle accessories. Background Art

[0002] The existing production of aerospace accessories generally requires drilling, grinding and other processing operations on the accessories. Since burrs will be generated on the surface of aerospace accessories during the processing, the aerospace accessories need to be ground and polished. However, a large amount of dust will be generated during the grinding process, which will cause the dust to adhere to the surface of the aerospace accessories and affect the surface finish. Therefore, a dust removal device is needed to clean the dust on the surface of the aerospace accessories.

[0003] At present, a Chinese utility model with publication number: CN213645081U discloses a dust removal device for the production of aerospace vehicle accessories, including a main body component, a driving component and a cleaning component, the main body component including a shell, a support rod, a brush, a spring and a box body, the outer wall of the box body is arranged on the inner wall of the shell body, the support rod is arranged on the top of the shell body, and two first grooves are symmetrically provided inside the support rod; by starting the motor, the motor drives the first rod body to rotate, so that the first rod body rotates through the first bevel gear transmission connecting rod and the second bevel gear and other structures, so that the support rod drives the brush to rotate, thereby achieving the effect of removing dust from the accessories; starting the water pump, the water pump draws water from the water tank through the water inlet pipe, and through the mutual use of the water outlet pipe, the first water pipe and the spray head, the water is used to rinse the accessories, and at the same time, the accessories are cleaned with the brush, so as to further improve the dust removal effect of the accessories and avoid the health threat of dust to the staff.

[0004] When the existing dust collector is working, it is necessary to clamp and fix the aerospace accessories to prevent them from moving during the cleaning. However, when the aerospace accessories are clamped, there is a contact point between their surface and the clamping assembly, so this part will be blocked, so that the dust on the surface of the accessories cannot be fully blown away, affecting the dust removal effect of the aerospace accessories. At the same time, when dusting the aerospace accessories, the wind can only blow from one side to the other side, which also leads to poor dust removal effect on the other side of the aerospace accessories. It is necessary to manually remove the aerospace accessories from the clamping assembly and turn the other side towards the fan, which makes it impossible to complete the dust removal and cleaning of the workpiece in one go, thereby reducing the dust removal efficiency of the aerospace accessories.
