Abstract
The invention relates to a 35-degrees inverted-chamfering milling cutter which comprises a cutter body and a cutter bit fixed at one end of the cutter body, wherein the cutter bit comprises a main cylindrical cutter bit and an auxiliary conical cutter bit, center axial lines of the main cutter bit and the auxiliary cutter bit are in the same straight line, the diameter of a joint of the auxiliary cutter bit and the main cutter bit is greater than that of a joint of the auxiliary cutter bit and the cutter body, the main cutter bit is fixedly connected with the cutter body by virtue of the auxiliary cutter bit; main blades are uniformly embedded in the circumferential direction of the main cutter bit, auxiliary blades are uniformly embedded in the circumferential direction of the auxiliary cutter bit, an included angle between the center axial lines of the auxiliary blades and the cutter body is 35 degrees, all the main blades and the auxiliary blades are symmetric about the center axial line of the main cutter bit, and the taper angle of the auxiliary cutter bit is 70 degrees. The 35-degrees inverted-chamfering milling cutter is ingenious in structural design; by adopting the inclined 35-degrees blades and matching the inclined 35-degrees blades with a straight cutter, synchronous milling of 35-degrees inverted chamfering and circular holes with diameters of 88cm is realized, thus processing steps are reduced, the working efficiency is improved, and the processing cost is reduced.
Description
Technical field
The present invention relates to cutter field, particularly a kind of 35 ° of angular cutters instead.
Background technology
Milling cutter for Milling Process, there is the rotary cutter of one or more cutters tooth.During work, each cutter tooth cuts the surplus of workpiece successively off and on.Milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece etc. on milling machine.
According to purposes, milling cutter is divided into substantially: flat-end cutter, tack band angle cutting tool, profile milling cutter, rose reamer, T-shaped cutter, flute profile cutter and tertia cutter etc., and the milling cutter of prior art is all to manufacture according to standard, be mainly used in the processing of standard component, but for some nonstandard workpiece, but cannot be suitable for.
For part as shown in Figure 3, need to carry out circular hole processing, and 35 ° of instead processing at angle 7 are carried out in circular hole 6 one end, existing milling cutter need to just can complete by twice milling processing, and not only labor intensive, also increases production cost.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the deficiencies in the prior art, provide a kind of special coupling 35 ° of chamfer machining, and can synchronous processing diameter be 35 ° of 88mm circular hole instead angular cutters.
The technical solution adopted for the present invention to solve the technical problems is: a kind of 35 ° of angular cutters instead, comprise cutter hub and the cutter head that is fixed on cutter hub one end, described cutter head comprises cylindrical operator head and conical secondary cutter head, the central axis of described operator head and secondary cutter head is on same straight line, and the diameter of described secondary cutter head and an operator junction is greater than the diameter of secondary cutter head and cutter hub junction, and described operator head is fixedly connected with cutter hub by secondary cutter head;
Described operator head is circumferentially evenly inlaid with main blade, described secondary cutter head is circumferentially evenly inlaid with auxiliary-blade, angle between described auxiliary-blade and cutter hub central axis is 35 °, and each main blade and auxiliary-blade are all symmetrical about the central axis of operator head, and the cone angle of described secondary cutter head is 70 °.
For convenient casting processing, described cutter hub and cutter head are formed in one.
For can match machined diameter 80mm circular hole, described two be 60mm about the distance between the main blade of the central axis symmetry of operator head, and the diameter of described operator head is less than 60mm.
Described main blade and auxiliary-blade all have 6, and main blade and auxiliary-blade homogeneous one correspondence, and main blade afterbody joins with corresponding auxiliary-blade head.
The invention has the beneficial effects as follows, 35 ° of angular cutters instead of the present invention, structural design is ingenious, by adopting 35 ° of blades of tilting to match with straight knife, realized the instead circular hole of angle and diameter 88mm of 35 ° of synchronously millings, reduce procedure of processing, improved operating efficiency, reduced processing cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the instead structural representation of angular cutter of 35 ° of the present invention.
Fig. 2 is the instead right view of angular cutter of 35 ° of the present invention.
Fig. 3 is the part that milling cutter of the present invention processes.
In figure: 1. cutter hub, 2. operator head, 3. secondary cutter head, 4. main blade, 5. auxiliary-blade, 6. circular hole, 7. angle instead.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As depicted in figs. 1 and 2, a kind of 35 ° of angular cutters instead, comprise cutter hub 1 and with the cutter hub 1 integrated cutter head in one end, cutter head comprises cylindrical operator 2 and conical secondary cutter head 3, the central axis of operator 2 and secondary cutter head 3 is on same straight line, and the diameter of secondary cutter head 3 and operator 2 junction is greater than the diameter of secondary cutter head 3 and cutter hub 1 junction, operator 2 is fixedly connected with cutter hub 1 by secondary cutter head 3;
Operator 2 is circumferentially evenly inlaid with main blade 4, secondary cutter head 3 is circumferentially evenly inlaid with auxiliary-blade 5, angle between auxiliary-blade 5 and cutter hub 1 central axis is 35 °, and each main blade 4 and auxiliary-blade 5 are all symmetrical about the central axis of operator 2, and the cone angle of secondary cutter head 3 is 70 °.
Two is 60mm about the distance between the main blade 4 of the central axis symmetry of operator 2, and the diameter of operator 2 is less than 60mm.
Main blade 4 and auxiliary-blade 5 all have 6, and main blade 4 and auxiliary-blade 5 homogeneous one correspondences, and main blade 4 afterbodys join with corresponding auxiliary-blade 5 heads.In fact, main blade 4 auxiliary-blade 5 corresponding thereto interconnects, and on same straight line.
By the distance between symmetrical main blade 4 is arranged to 60mm, then mate 35 ° of inclination auxiliary-blades 5, can be 35 ° of millings instead in angle 7, just can be to the circular hole 6 of synchronous processing 88mm diameter correspondingly.
Blade is embedded in cutter head, utilizes bolt to be fixed, and facilitates later stage dismounting to whet a knife and safeguards.
The cone angle design of secondary cutter head 3 becomes 70 °, and the angle being between monolateral and middle bobbin thread is 35 °, just in time matches with the angle of inclination of secondary cutter 5.
Compared with prior art, these 35 ° instead angular cutter structural design is ingenious, by adopting 35 ° of blades of tilting to match with straight knife, 35 ° of synchronously millings instead angle 7 and diameter 88mm circular hole 6 have been realized, reduce procedure of processing, improved operating efficiency, reduced processing cost.
