Description

Technical Field

[0001] The utility model relates to the technical field of burr grinding, in particular to a burr grinding device. Background Art

[0002] Grinding is a type of surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper with high hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. It is usually done manually, but can also be done with pneumatic or electric equipment.

[0003] The existing Chinese patent with patent announcement number CN210060712U proposes a handheld electric grinder, including a shell, the shell is fixedly connected to the shell, a motor is fixedly installed inside the shell, the motor is sleeved on a rotating column, the end of the rotating column away from the motor is threadedly connected to a bolt, the rotating column is rotatably connected to the shell, the rotating column is rotatably connected to the connecting column, the top of the connecting column is fixedly connected to the shell, the bottom end of the side wall of the connecting column is fixedly connected to a convex ring, an airbag is fixedly installed on the convex ring, the airbag is connected to one end of an air pipe, and the other end of the air pipe is fixed to the side wall of the protrusion and is in the same plane as the side wall of the protrusion; when the grinding wheel rotates, it squeezes the spring sheet, thereby squeezing the airbag, so that the gas in the airbag is discharged through the air pipe, and the air pipe is oriented outward and downward, so that air is blown along with the debris splashed to the top of the grinding wheel, thereby preventing the debris from entering the gap between the grinding wheel and the convex ring.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: when a handheld grinder is used to grind metal parts, a large amount of high-temperature metal debris will be generated due to the friction between the steel brush and the metal parts, which can easily burn the user's skin and pose a safety hazard. At the same time, it will also cause high-temperature metal debris to splash, affecting the working environment.

[0005] For this reason, a burr grinding device is proposed. Utility Model Content
