The application provides a middle shaft bowl set
surface grinding device capable of reducing
noise, relates to the technical field of middle shaft bowl set
grinding, and comprises a fixed base, one side of the fixed base is provided with a fixed support plate, the top of a sealing cover is provided with an
air pump, an output end of the
air pump is provided with a main flow
pipe, the sealing cover is located on the outer side of a positioning cover, the side of the main flow
pipe is connected with a
branch flow
pipe, the
branch flow pipe penetrates through the side of the sealing cover and is provided with a cleaning pipe, the cleaning pipe is installed on the inner side of the sealing cover, a groove is formed in the cleaning pipe, and the cleaning pipe is located at the bottom of a sound-absorbing plate. High-pressure
airflow is guided to the cleaning pipe through the main flow pipe and the
branch flow pipe, the high-pressure
airflow sprayed from the groove of the cleaning pipe is used for cleaning the
metal dust attached to the sound-absorbing plate, the problem that the
metal dust is accumulated on the sound-absorbing plate is effectively avoided, and the problem that the
metal dust generated in the
grinding process is diffused along with
airflow and attached to the surface of the sound-absorbing material, thereby seriously weakening the
noise reduction effect is solved.
