Abstract
The invention discloses a milling cutter, comprising a cutter body and a blade, wherein the cutter body comprises a cutter bar and a cutter head arranged at one end of the cutter bar, at least two fixed parts are arranged on the cutter head at intervals in peripheral directions of the cutter head, each fixed part is concavely provided with a mounting groove for installing the blade, the blade is detachably arranged in the corresponding mounting groove on the cutter body. The distance from each mounting groove central position to the center of the cutter head is at least partially different, so that the blade is selectively arranged in the corresponding mounting groove according to different degreed of wear in the using process. The milling cutter can repeatedly use the blade, thus the using cost of the cutter can be greatly saved.
Description
Technical field
The present invention relates to a kind of cutter structure, relate in particular to a kind of milling cutter.
Background technology
Milling cutter is used extremely wide in Milling Process, can process especially big section difference, groove, inclined-plane, plane etc.Existing milling cutter is made up of cutter hub and the blade that is fixed on the fixed part of cutter hub usually, and blade can can't continue to use after using a period of time because of wearing and tearing shorten.Therefore, in Milling Process, need often to change the blade that shortens because of wearing and tearing, so, make the cutter use cost sharply increase.
Summary of the invention
In view of foregoing, be necessary the milling cutter that provides a kind of use cost lower.
A kind of milling cutter; It comprises cutter hub and blade; This cutter hub comprises knife bar and is arranged at the cutterhead of knife bar one end; Its periphery direction of this cutterhead upper edge convexes with at least two fixed parts at interval, is concaved with one on each fixed part in order to install the mounting groove of this blade, and this blade removably is installed in the mounting groove corresponding on this cutter hub; The distance at each mounting groove center position cutterhead center part at least is different, so that blade in use is installed in the mounting groove of correspondence along with degree of wear different choice ground.
Another kind of milling cutter; It comprises cutter hub and blade, and this cutter hub comprises knife bar and be installed in the cutterhead of knife bar one end that its periphery direction of this cutterhead upper edge convexes with at least two fixed parts at interval; Be concaved with a mounting groove on each fixed part; This blade removably is installed in the mounting groove of fixed part, and when this blade was contained in different mounting grooves, the length that its blade exposes mounting groove was different.
Groove in order to fixed blade at least two fixed parts of said milling cutter has different positions; Therefore; Can select different recesses that new blade or degree of wear different blades are installed as required; Repeat repeatedly to utilize blade like this, can prolong cutter life to greatest extent, thereby reduce use cost.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment milling cutter of the present invention is done further to specify.
See also Fig. 1 and Fig. 2, milling cutter 100 of the present invention comprises cutter hub 12, blade 14 and tightening member 16, and blade 14 removably is installed on the cutter hub 12 through tightening member 16.
Being appreciated that cutterhead 124 can adopt with knife bar 122 one-body molded modes processes or removably is installed on this knife bar 122.
Its periphery direction of cutterhead 124 upper edges convexes with plurality of fixed portion 126 at interval, forms a chip area 128 between per two adjacent fixed portions 126.On the radial side of chip area 128, be concaved with a mounting groove 129 on each fixed part 126 with installing blade 14.The position of contiguous mounting groove 129 connects and offers a fixing hole 120 on each fixed part 126.The distance at center position cutterhead 124 centers of each mounting groove 129 part at least is different, so that can blade 14 be installed in the corresponding mounting groove 129 different the selection according to the degree of wear of blade 14.That is when same blade 14 was contained in the different mounting groove 129 of the distance at center position cutterhead 124 centers, the length that blade 14 exposes mounting groove 129 was different, and accordingly, the processing dimension of milling cutter 100 is different.
In this embodiment, the quantity of fixed part 126 is three, and it evenly is laid in the periphery of cutterhead 124.Blade 14 is an Atria angle of throat sheet, and accordingly, each mounting groove 129 that is arranged with on fixed part 126 is the general triangular groove-like, center position cutterhead 124 centers of one of them mounting groove 129 nearest so that install a new blade 14; The distance at center position cutterhead 124 centers of all the other mounting grooves 129 becomes big gradually so that degree of wear different blades 14 is installed.Can being provided with according to tool wear degree in the use and acceptable tool abrasion of center position cutterhead 124 centers of mounting groove 129 apart from gap size; Continue to use in the corresponding mounting groove 129 so that the blade 14 after the wearing and tearing can be packed into, prolong 14 service lifes of blade to greatest extent.
Be appreciated that cutterhead 124 also can be arranged to any a plurality of fixed parts 126 such as two, four, five or six, the position of the mounting groove of offering in the different fixing portion 126 129 can be inequality fully, and is also can part inequality.During use, can select once only to install a blade 14, also can select a plurality of blades 14 of once mounting.
Shown in Figure 3 for to utilize 100 pairs of workpiece of milling cutter 200 to carry out the view that facing cut adds man-hour.When utilizing 100 pairs of workpiece of milling cutter 200 of the embodiment of the invention to carry out Milling Process, milling cutter 100 rotations are also carried out Milling Process along preset machining path to workpiece 200.The cutterhead 124 of milling cutter 100 is rotated counterclockwise and along being parallel to the direction of the side of workpiece 200, promptly direction shown in the horizontal arrow is done straight-line feed among Fig. 3 around its cutter hub 12, handles workpiece 200 is carried out milling.
When in use being worn, blade 14 shortens the back in former mounting groove 129, can't continue to use the time; Can get off polishing back and being installed in the mounting groove 129 far away of the center of another center position cutterhead 124 of this blade removal be handled to continue that workpiece 200 is carried out milling.Under the situation that does not change cutter hub 12, a new blade 14 can use repeatedly like this; Simultaneously; Because new blade 14, degree of wear different blades 14 is of different sizes and edge strength; Can select only mounting groove 129 and blade 14 according to working (finishing) area, the material hardness of workpiece to be processed 200; Thereby prolong the service life of cutter to greatest extent, practiced thrift the use cost of cutter greatly.
In addition, those skilled in the art also can do other variation in spirit of the present invention.Certainly, these all should be included in the present invention's scope required for protection according to the variation that the present invention's spirit is done.
