Further setting the following steps: each heat dissipation groove extends from the connecting part to the outer ring of the polishing part and is gradually bent towards the same side to form an arc.
Through adopting above-mentioned technical scheme, set the radiating groove to crooked rectangular shape and cooperate the vortex air current that the emery wheel produced at high-speed rotatory in-process, make the vortex air current can enter into the radiating groove with the efficient to heat on the emery wheel is taken away to more the efficient, plays better cooling effect.
Further setting the following steps: a steel ring is arranged on one side surface of the connecting part, which faces away from the protruding direction of the connecting part, an extending part extending into the mounting through hole is arranged on the steel ring, and a plurality of positioning columns embedded into the connecting part are fixedly distributed on the steel ring.
Through adopting above-mentioned technical scheme, the setting of steel ring strengthens clamping strength, makes the emery wheel be difficult to appear bursting apart, further promotes the area of contact of steel ring and abrasive material through the reference column to promote the fixed connection intensity between steel ring and the abrasive material. The extension portion is arranged to protect the abrasive formed in the mounting through hole.
Further setting the following steps: one side of the connecting part back to the polishing arc-shaped surface is provided with a heat insulation pad.
Through adopting above-mentioned technical scheme, the existence separation emery wheel body of heat insulating mattress and grinding tool's direct contact reduces heat conduction on the emery wheel body to grinding tool, avoids grinding tool to appear high overheated phenomenon, plays the guard action to grinding tool, prolongs its life.
Further setting the following steps: the heat insulation pad is provided with a plurality of heat dissipation holes, the heat dissipation holes radially penetrate through the heat insulation pad along the installation through holes, and the heat dissipation holes are distributed around the circle center of the installation through holes.
Through adopting above-mentioned technical scheme, the setting up of louvre plays the cooling action to the heat insulating mattress, further reduces the heat transfer.
In conclusion, the utility model has the following beneficial effects: the utility model has better polishing quality, wider universality, stronger practicability and stronger heavy load.
