Description

Hard alloy grinding rod for grinding inner hole of belt wheel

Technical Field

The utility model belongs to the technical field of car CVT makes, especially, relate to a carbide grinding pin for band pulley hole abrasive machining.

Background

At present, in traditional CVT band pulley hole grinding, the grinding pin is mostly ordinary high-speed steel material, and the rigidity is relatively poor, and when the emery wheel of high-speed rotation was maintained, the emery wheel kick-backed easily, leads to often can appear unevenness, tapering behind the emery wheel maintained to lead to the hole white trace and 10 μm's tapering to appear.

Therefore, the prior art is to be improved.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a carbide grinding pin for band pulley hole abrasive machining to solve the technical problem who mentions in the background art, make the hole tapering stable within 3 mu m, eliminated the white trace of hole simultaneously.

The utility model discloses a carbide grinding pin for band pulley hole abrasive machining, including high-speed steel thread head, carbide cutter arbor and be used for the HSK40 handle of a knife be connected with the lathe main shaft, carbide cutter arbor one end is connected with high-speed steel thread head, and the other end is connected with HSK40 handle of a knife.

Preferably, the HSK40 knife handle comprises an HSK-C40 knife handle.

Preferably, the grinding wheel further comprises a locking nut and a workpiece to be machined, wherein the workpiece to be machined is provided with an inner hole, the high-speed steel threaded head is connected with the workpiece to be machined through the locking nut, and a first grinding wheel is arranged between the inner hole and the hard alloy cutter bar.

The utility model discloses a carbide grinding pin for band pulley hole abrasive machining adopts the high rigidity of carbide cutter arbor, solves the not enough problem of current grinding pin rigidity for the hole tapering is stable within 3 mu m (requires 4 mu m), has eliminated the white trace of hole simultaneously.
