Abstract

The utility model relates to a staggered tooth universal type indexable milling cutter. The utility model is applied to the high-efficiency milling and processing with large allowance for the common milling machine. The utility model is characterized in that cutter blades are arranged in a staggered tooth structure; the cutter blades and a cutter blade seat are respectively and directly positioned with the bottom surface of a cutter groove of a cutter body and the top surface of a circular groove of the cutter body. The cutting depth can achieve from 15 millimeters to 26 millimeters. Simultaneously, the cutter blade seat can be changed, and thus the utility model becomes a common indexable face milling cutter. The utility model has the advantages of novel structure, reasonable and compact design, good manufacturability, strong universality, high cutting efficiency, and formation of serial products. The diameter of the milling cutter is from phi 80 to phi 800 millimeters, which conforms to the standard of a GB5342-85 indexable face milling cutter product.

Description

Side set general-purpose type indexable face milling cutter

The utility model is applied to the high-efficient milling processing of the big surplus of plain-milling machine.

At present domestic and international tool production producer, modular blade bearing and the cutter hub annular groove end face axial positioning structure indexable face milling cutter produced as Sweden SANDVIK and German WALTER company, for homemade common X53K.X52K milling machine, its poor rigidity, power are little, run into allowance big (15-26 millimeter), blade cutting edge short (16 * 16 millimeters square blades) can only adopt repeatedly feed to finish usually, therefore stock-removing efficiency is low, and non-cutting time is long.

The purpose of this utility model is that a kind of side set general-purpose type indexable face milling cutter new construction will be provided, it can effectively carry out the processing of big cutting-in (15-26 millimeter) high-efficient milling on plain-milling machine, working angles is brisk steadily, chip removal is smooth, shorten the non-cutting time of repeatedly feed, simultaneously can easier change blade bearing again, make blade change common arrangement mode into, become general allowance (3-8 millimeter) milling indexable face milling cutter, thereby make milling cutter reach highly versatile, use widely, reduce the effect of the cost of charp tool.

The technical solution of the utility model is to realize like this; On the basis of modular blade bearing and cutter hub annular groove end face axial positioning structure indexable face milling cutter, be improved to side set general-purpose type new construction, it is characterized in that: cutter hub each etc. in the dark cutter groove, be equipped with staggered successively before blade bearing and back blade bearing.Cutter hub cutter groove is 90 ° of square grooves, and front and back blade bearing and briquetting be 11 ° of inclined-planes each other, blade and location, cutter hub square groove bottom surface, front and back blade bearing and cutter hub annular groove end face location.Blade bearing before back blade bearing is all changed becomes common indexable face milling cutter.

The beneficial effect that the utility model is compared with prior art had; The indexable face milling cutter that adopts side set to arrange during big cutting-in; Use the X53K milling machine, 10 kilowatts of power are processed No. 45 steel, 0.1 millimeter of feed engagement, and cutting depth can reach 26 millimeters, stable cutting, chip removal is smooth.As all being replaced with preceding blade bearing, when blade was the indexable face milling cutter of common arrangement, above-mentioned condition was constant, and feed engagement is 0.2 millimeter, and cutting depth can reach 8 millimeters, reaches the effect of common indexable face milling cutter, accomplished that a cutter is dual-purpose.

Concrete structure of the present utility model is provided by following examples and accompanying drawing; Fig. 1 is a front view of the present utility model, and Fig. 2 is a blade clamping and positioning section of structure.The utility model is by cutter hub (1), briquetting (2), double end (about revolve) screw (3), and blade (4), preceding blade bearing (5), back blade bearing (6), totally 6 bare bones are formed.Shown in Figure 1: cutter hub (1) each etc. in the dark cutter groove, be equipped with to hand over successively and borrow the preceding blade bearing (5) arranged and back blade bearing (6), promptly adorn an identical blade bearing every a cutter groove.Respectively front and back blade bearing (5), (6), the square groove bottom surface that is adjacent to cutter hub (1) and annular groove end face are directly located, then by briquetting (2) by double end (about revolve) screw (3), front and back blade bearing (5), (6) are clamped.Shown in Figure 2, cutter hub (1) cutter groove is 90 ° of square grooves, and front and back blade bearing (5), (6) and briquetting (2) be 11 ° of inclined-planes each other.Before and after blade (4) is contained in respectively in the insert groove of blade bearing (5), (6), blade (4) back knife face and location, cutter hub (1) square groove bottom surface, by briquetting (2) by double end (about revolve) screw (3) clamping.

Realize best way of the present utility model; Shown in Figure 1: when blade (4) side set was arranged, its position of staggering was by front and back blade bearing (5), (6) insert groove location, and 2 millimeters of blade cutting edge overlaids make cutting image become straight line, so make cutting depth can reach the 15-26 millimeter.Reduce cutting force in order to eliminate the vibration of working angles this moment, adopt known chip dividing groove formula indexable insert tip, throw away tip, the use that will be staggered of odd bin on the blade cutting edge and even bin.When the utility model was preceding blade bearing (5) at replacing whole back blade bearings (6), then blade (4) became common (non-side set) arrangement mode, is the common indexable face milling cutter that is used for general allowance (3-8 millimeter).The utility model has formed series of products, and 800 millimeters of milling cutter diameter φ 80-φ meet GB5342-85 " indexable face milling cutter " product standard.

Claims

1, a kind of side set general-purpose type indexable face milling cutter, it comprises: briquetting (2), double end (about revolve) screw (3), blade (4), it is held to levy and is:

A, cutter hub (1) each etc. in the dark cutter groove, be equipped with staggered successively before blade bearing (5), and back blade bearing (6);

B, cutter hub (1) cutter groove are 90 ° of square grooves, front and back blade bearing (5), (6), and with briquetting (2) 11 ° of inclined-planes each other, blade (4) and location, cutter hub (1) square groove bottom surface, front and back blade bearing (5) (6) and cutter hub (1) annular groove end face location;
