A grinding device for machining mechanical parts

Technical Field

The utility model relates to the technical field of mechanical parts grinding, in particular to a grinding device for machining mechanical parts.

Background Art

Mechanical parts, also known as mechanical elements, are the basic components of machinery and are inseparable individual parts that make up machinery and machines. When processing mechanical parts, it is necessary to use a grinding device to increase the smoothness of the surface of the mechanical parts. Only when the surface of the mechanical parts is smooth can it be ensured that there will be no jerky conditions when the device is running.

Announcement No. "CN217344927U" provides a grinding device for mechanical parts processing. It is equipped with a collection port. When the device is in use, the servo motor on the right side drives the grinding wheel at the output end to rotate and grind. The dust generated by grinding will be directly collected through the collection port at the bottom. The rotating motor on the right side of the bottom will drive the output exhaust fan to exhaust air, thereby absorbing the metal chips floating near the collection port, greatly reducing the problem of floating dust affecting the health of workers.

However, the above technical solutions and the prior art have the following defects:

Although the grinding equipment used for machining mechanical parts can absorb the metal chips floating near the collection port by exhausting the exhaust fan driven by the rotating motor, the dust suction structure needs to power the rotating motor separately when in use, thereby increasing the power consumption of the grinding equipment. In addition, the grinding equipment is not provided with a corresponding filtering structure to filter the absorbed metal chips and dust, resulting in some metal chips and dust being mixed in the air discharged by the exhaust fan, thereby failing to effectively reduce the problem of dust floating affecting the health of workers, and having poor practicality.
