Description

A kind of replaceable rack type cutter of cutter head
Technical field
The utility model is related to cutting tool field, more particularly to a kind of replaceable rack type cutter of cutter head.
Background technology
Cutter is to be used for the instrument of machining, also known as cutting element in machine-building.Most of cutter is that machine is used , but also have hand.Because the cutter used in machine-building is substantially all for cutting metal material, so " cutter " one Word is typically just interpreted as metal cutting tool.
Rack type cutter is the cutter that straight-tooth, helical teeth and herringbone bear are processed by generating principle.The profile of rack type cutter much like rack, So also referred to as rack cutter.Rack type cutter has two kinds of straight-tooth and helical teeth.Straight-tooth rack type cutter is mainly used in processing straight-tooth gear and oblique Gear;Skewed tooth combing tool is mainly used in processing herringbone bear, undercut very narrow duplicate gear and shouldered helical gear.
Rack type cutter is the important component of cutting processing system, is to influence the key factor of product quality.Batch production During, rack type cutter performance can increase with use time and gradually degenerate, and then influence crudy, it is therefore necessary to which cutter is entered Row is changed to avoid the occurrence of major quality loss.However, in cutter changing, it is necessary to which whole cutter is changed.Entirety is more Tool changing has, and program is complicated, and frequently cutter changing can cause a large amount of production disruptions, reduces useful efficiency, increases the cost of charp tool. By cutter integral replacing, waste serious, production cost can be increased.Also, the replacement cycle is long and can increase the general of cutter failure Rate, and then increase extra maintenance cost.
Utility model content
The utility model overcome the deficiencies in the prior art can be individually replaced there is provided a kind of cutter head, it is cost-effective and change The rack type cutter of time.
To solve above-mentioned technical problem, the utility model uses following technical scheme:
Mounting seat, the cutter head are provided with a kind of replaceable rack type cutter of cutter head, including cutter hub and cutter head, the cutter hub On be provided with some blades, the tool cutting edge angle of the blade is 60 °~70 °, and the auxiliary angle of the blade is -13 °~-5 °, described Mounting hole and arch posting are provided with mounting seat.
As preferred scheme of the present utility model, cutter hub connecting portion is provided with the cutter hub, the cutter head is away from blade One end be provided with cutter head connecting portion, the cutter hub connecting portion and cutter head connecting portion pass through some bolt connections.
As preferred scheme of the present utility model, pad is provided between the cutter hub connecting portion and cutter head connecting portion.
As preferred scheme of the present utility model, two groups of the installation seat, two groups of mounting seats are respectively arranged at cutter hub Two ends.
As preferred scheme of the present utility model, the tool cutting edge angle of the blade is 65 °.
As preferred scheme of the present utility model, the auxiliary angle of the blade is -9 °.
Compared with prior art, the beneficial effects of the utility model are:
1st, mounting hole and arch posting are provided with mounting seat of the present utility model, it is firm to install, and is avoided that rack type cutter Loosened in the course of work, cause cutter easily damaged.Cutter is impaired and frequently changes cutter, causes less efficient, cost to improve.This The cutter hub connecting portion and cutter head connecting portion of utility model are by some bolt connections, when needing to change cutter head, it is only necessary to turn on Bolt, changes cutter head.The utility model need not change whole cutter, it is to avoid cumbersome step during integral replacing cutter, and Replacing construction can be saved, efficiency is improved.Only change cutter head, it is to avoid the waste of cutter hub, can be cost-effective.
