Abstract

The utility model provides a cutter with a malposed cutter head, comprising a main axle; a clamp nut respectively arranged on the two ends of the main axle; a cutter body mounted between the clamp nuts; a groove on the cutter body; a cutter head fixed in the groove; a cutter blade on the cutter head, wherein the length L1 of the cutter head is larger than the width L2 of the groove; a key groove on the cutter body and a malposition key in the key groove; wherein one end of the cutter head and one side of the cutter body are on the same plane; the cutter blade is parallel to the center line of the main axle; the included angle between the cutter blade and the center line of the main axle is 1-45 degree. The cutter head is mounted by the malposition way to prevent shaving trace on the adjacent blades during shaving process, the shaved material surface is smooth and flat, the structure is simple and the cost is relative low.

Description

A kind of planing tool of misplaced cutter head

Technical field

The utility model belongs to mechanical field, relates in particular to a kind of planing tool of misplaced cutter head.

Background technology

Fritter shape planing tool now commonly used, the planing tool of this structure exist the local shortcoming of digging trace that easily produces of having a common boundary between two planing tools, though and the planing tool that has has solved the place that planing tool has a common boundary and has produced the problem of digging trace, complex structure, cost is higher.

Summary of the invention

The utility model provides a kind of planing tool of misplaced cutter head, has solved the planing tool in the background technology and has produced plane trace and the high shortcoming of complex structure cost.

The technical solution of the utility model is achieved in that a kind of planing tool of misplaced cutter head, comprise main shaft, clamp nut is established at the main shaft two ends respectively, be equipped with cutter hub between two clamp nuts, establish groove on the cutter hub, fixedly be equipped with cutter head in the groove, establish blade on the cutter head, the length L 1 of cutter head is established keyway greater than the width L2 of groove on the cutter hub, be equipped with the dislocation key in the keyway;

Cutter head one end and cutter hub one side are in same plane;

Blade and alignment of shafts line parallel;

Blade is with respect to being 1 °～45 ° angles between the spindle centerline.

The beneficial effects of the utility model are: the utility model adopts the installation method that misplaces with cutter head, has avoided adjacent knife blades to produce the problem of digging trace in the slicing process, and the material smooth surface of slicing is smooth, simple in structure, and cost is lower.
