Detailed Description
The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.
As shown in fig. 1 to 4, a multifunctional composite cutter for drilling, turning and milling comprises a drill body 1 and a transposition blade 2, wherein the radial cross section of the drill body 1 is semicircular, one end of the drill body 1 is obliquely provided with a first blade 3 and a second blade 4, the first blade and the second blade 4 are symmetrically arranged relative to the axis of the drill body 1, one ends of the first blade 3 and the second blade 4 are intersected with the axis of the drill body 1 to form a cutting edge, the cutting edge can be used for turning, drilling and boring of an end face and an outer cylindrical face, the transposition blade 2 is detachably arranged on the plane of the drill body 1 and close to the cutting edge, the transposition blade 2 can be used for hole positioning drilling, hole chamfering and contour chamfering, so that the cutter has multiple processing functions, the cutter changing time and the tool position resource transposition of a tool magazine of a processing center can be effectively saved, the blade 2 is detachably connected to the drill body 1 in a screw pressing mode, the screw can be screwed and loosened, so that the indexable insert 2 can be rotated to replace the machining tool tip 5, and the screw can be screwed down to replace the indexable insert 2.
Further, as shown in fig. 2, the indexing insert 2 has a polygonal structure with a relief angle, and the indexing insert 2 has at least two inner angles equal to the cutting edge angle. The transposition blade 2 is of a polygonal structure, the crossed edges form a cutter point 5 for machining, the transposition blade 2 is provided with a plurality of cutter points 5 for machining, when one cutter point 5 is damaged or worn, the transposition blade 2 can be rotated, and the other cutter point 5 of the transposition blade 2 is in a working state, so that the integral replacement of the blade is avoided, the service life of the blade is prolonged, the cost is reduced, and the utilization rate of the blade is improved. One end of the first cutting edge 3 and one end of the second cutting edge 4 are intersected on the axis of the drill body 1 to form a cutting angle which is 90 degrees, 60 degrees or 120 degrees so as to meet different cutting requirements, the shape of the transposition cutting blade 2 is respectively square, rhombus or regular hexagon with an inner angle of 120 degrees according to the requirement of the cutting angle, two sides of the tool nose 5 are respectively coincided and corresponding to the first cutting edge 3 and the second cutting edge 4, and normal processing of the tool nose is guaranteed.
Furthermore, the edges of the indexing insert 2 are intersected to form a tool nose 5, the arc radius of the tool nose 5 is 1.2 mm-1.6 mm, and the back angle of the indexing insert 2 is 47 degrees. The service strength of the indexing blade 2 is mainly based on the strength of the tool nose 5, and the arc radius of the tool nose 5 is too small and easy to collapse and too large, so that the working range is influenced (an unnecessary chamfer is left at a small hole opening); in order to avoid interference of the edges corresponding to the tool nose 5, the tool nose rotates to form a 90-degree conical recess, if the rear angle of the tool nose 5 is smaller than 45 degrees, the edges corresponding to the tool nose 5 and the conical surface are extruded and scraped, and the strength is the best under the premise of avoiding scraping at 47 degrees.
Further, as shown in fig. 1 and fig. 3, still include handle of a knife 6, the one end that transposition blade 2 was kept away from to body of boring 1 is fixed with erection column 7, erection column 7 is connected with handle of a knife 6 detachable, mounting hole 8 has been seted up to the one end of handle of a knife 6, be provided with location awl 9 in the mounting hole 8, location awl 9 sets up with handle of a knife 6 is concentric, 7 slidable of erection column set up in mounting hole 8, the taper hole has been seted up to the one end that body of boring 1 was kept away from to erection column 7, taper hole and 9 adaptations of location awl, the adaptation of location awl 9 and taper hole is passed through in the installation of body of boring 1 and handle of a knife 6 and is centered, thereby guarantee the installation accuracy of body of boring 1, avoid the cutter during operation to cause the influence to the machining precision.
Further, diamond, cubic boron nitride or cemented carbide is used as the material of the drill body 1 and the indexing insert 2. Present handle of a knife 6 and cutter are integral structure all, because handle of a knife 6 not with work piece direct contact, only be used for installing the cutter on the lathe, consequently, it is lower to the material strength requirement of handle of a knife 6, and bore body 1 and transposition blade 2 and work piece direct contact, required material strength is higher, and adopt integral structure, it is unanimous to lead to the material of handle of a knife 6 and cutter, thereby the waste of handle of a knife material has been caused, material cost has been improved, 2 detachable of this application transposition blade are installed on boring body 1, simultaneously, bore body 1 detachable and install in handle of a knife 6, the cutter wholly adopts split type structure, only need to change the part of damage can, avoid the whole change, the cost is reduced.
Furthermore, a positioning bolt 10 is connected to one side of the tool holder 6 through threads, the positioning bolt 10 is used for limiting the axial movement of the mounting column 7, the mounting column 7 is in a step shape, and when the taper hole is matched with the positioning cone 9, the positioning bolt 10 abuts against the step of the mounting column 7. During the installation, penetrate mounting column 7 in the mounting hole 8 earlier, and make the taper hole on the mounting column 7 and the centering awl 9 adaptation on the handle of a knife 6, then follow one side screw in of handle of a knife 6 with positioning bolt 10, positioning bolt 10 passes mounting hole 8 and 6 threaded connection of handle of a knife, positioning bolt 10's side and mounting column 7's ladder butt simultaneously, thereby restrict the axial displacement of mounting column 7, a be used for fixing body 1, thereby the installation of installation body 1, only need screw down positioning bolt 10 during the dismantlement with the body 1 from mounting hole 8 in pull out can, make the installation of body 1 and dismantlement simple more swift.
The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
