Cutter heads are connected to a cutter body; the outer circumferential surface of the cutter body is provided with a guide bar; the cutter body is provided with an axial through hole; the cutter heads are in a step shape, the large diameter end is a cone, and the small diameter end has a thread structure and is screwed into a screw hole of the cutter body; the number of the cutter heads is two or more; the end face of the cutter body is provided with a groove; the inside of the groove and the sides of the cutter heads are provided with locking stop taper pins; the guide bar is connected to the cutter body through a fastening screw; and the outer diameter size of the guide bar is greater than the maximum outer diameter of the cutter heads. The cutter has simple structure, good machining manufacturability, and convenient replacement and restoration, and is suitable for machining various stepped holes. The cutter is strong in generality, is protected by the locking stop taper pins and has good straightness. The cutter body is provided with the guide bar with the functions of guiding and antivibration, so that the cutter can effectively ensure that the cutter heads do not damage the surface of an inner hole preliminarily machined, makes workpieces meet the high technical requirements of dimension precision, verticality, coaxiality and the like, and improves product percent of pass.
Description
Affiliated technical field
The present invention relates to the multi-cutter boring and processing cutter of the deep hole step end face in a kind of field of machining.
Background technology
In machine industry, the step end face difficulty of processing of deep hole is bigger, particularly numerical control boring and milling axle class; It structurally has the characteristics of a plurality of stepped holes, and in specification requirement, its dimensional accuracy, form and position tolerance and surface roughness have very high requirement; The aperture forms the deep hole bottom conical surface after drawing hinge processing, this will directly have influence on part assembling and equipment performance; Therefore; Must eliminate the bottom conical surface through special process tool, and improve its machining accuracy, reach the specification requirement of dimensional accuracy, axiality and the perpendicularity of the step end face of deep hole; Simultaneously, because the shaped hole dimensional accuracy of preceding working procedure, form and position tolerance than higher, have increased difficulty for follow-up bore hole end face; Use universal cutter; Cause very easily that bore area scratches, the size boring is big, bottom end face perpendicularity and roughness do not reach and require and cause and scrap, so follow-up bore hole difficulty of processing is quite big; Can not reach the specification requirement of end face processing, have a strong impact on product quality.
Summary of the invention
For overcoming the deficiency of prior art, goal of the invention of the present invention is to provide a kind of deep hole step end face multi-cutter boring and processing cutter, makes the processing of deep hole step end face reach standard-required with realization, and does not influence the purpose of non-machined surface.
Technical solution of the present invention is: cutter head is connected on the cutter hub, it is characterized in that: on the periphery of cutter hub gib block is housed, cutter hub axially is a through hole.
Characteristic of the present invention is that also described cutter head is a stairstepping, and bigger diameter end is taper, and miner diameter end is a helicitic texture; Be combined in the screw of cutter hub; Cutter head is two or more, and cutter hub is fluted at its end face, in groove, the side of cutter head is equipped with and only locks taper pin.
Gib block of the present invention is connected on the cutter hub with trip bolt, and the outside dimension of gib block is greater than the maximum outside diameter of cutter head.
One end of cutter hub of the present invention is a helicitic texture.
During bore hole, earlier with the cutter linear advancement, when treating that cutter walks to degree of depth requirement, workpiece rotates, the cutter rectilinear motion, and cutting endoporus and end face are to standard-required.
The present invention compared with prior art has the following advantages:
1, because cutter head and cutter hub are thread connection, easy accessibility has and only locks taper pin and protect and lead, and linearity is good, and external screw thread is convenient to process;
2, on the cutter hub gib block is housed, has guiding and antihunt action, can guarantee effectively that cutter head does not injure the bore area that has passed through preliminary working, make workpiece reach high-tech requirements such as dimensional accuracy, perpendicularity, axiality, improve product percent of pass;
3, cutter structure is simple, and processing technology is good, is convenient to change, repair, and is fit to all kinds of shoulder hole processing, highly versatile.
Description of drawings
Below in conjunction with accompanying drawing the present invention is made further detailed description.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is user mode figure of the present invention.
The specific embodiment
Like Fig. 1, shown in Figure 2, cutter head 1 of the present invention is a double-pole, ladder-type structure; Adopt the W18Cr4V material to process, have characteristics such as excellent cutting performance, durability are strong, its bigger diameter end is taper; Miner diameter end is a helicitic texture, links with cutter hub 2 internal thread holes, and dismounting is quick; Cutter hub 2 is fluted at its end face, and in groove, the side of cutter head 1 is equipped with and only locks taper pin 5, adopts the taper pin mode to connect, bottom outlet is 3 degree taperings, realizes self-locking, convenient disassembly; During use, according to the need bore size, cutter head 1 peripheral milling is extremely less than endoporus 0.05-0.1mm, to reach the specification requirement that needs bore hole; Cutter hub 2 adopts the 40Cr material to process, and through modifier treatment, has stronger mechanical performance, along its axial direction; There is through hole at the center, can play the effect of flushing, chip removal and cooling cutter, on cutter hub 2; With the axis normal direction screw is arranged, match, be used for gib block 3 usefulness trip bolts 4 are connected in cutter hub 2 with the hole of gib block 3; Be convenient to regulate and replacing, an end of cutter hub 2 is a helicitic texture, is convenient to connect with knife bar; 4 gib blocks 3 are housed on the periphery on the cutter hub 2, are symmetrical distribution, steering capability is stable; Effectively guarantee Tool in Cutting size and form and position tolerance; Gib block 3 appearance and sizes are less than endoporus 0.02-0.05mm, greater than cutter 0.03-0.05mm, make when cutter advances, not scratch inner surface.
As shown in Figure 3, during bore hole, drawing the hole after the hinge with workpiece is bullport, earlier with cutter 6 of the present invention (cutter 6 comprises cutter head, cutter hub, gib block, trip bolt, only locks taper pin) linear advancement; Workpiece 7 does not rotate, and when treating that cutter 6 walks to degree of depth requirement, workpiece 7 begins to rotate, simultaneously; Cutter 6 linear uniform motion, cutting endoporus and end face are to standard-required, and at this moment, knife bar 8 endoporus feed emulsion; Get into cutter 6, the effect of play cooling, lubricating, cutter 6 endoporus can play the effect of chip removal.
