Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 to 4, the present invention provides a drilling and milling integrated tool for processing a workpiece with a hole end surface.
The drilling and milling integrated cutter comprises a milling cutter sleeve 1, a drill bit 2 and a fixing piece 3, wherein the fixing piece is used for fixing the relative position between the milling cutter sleeve and the drill bit. The milling cutter sleeve is of a cylindrical structure, the specific milling cutter sleeve is of a cylindrical structure, a milling cutter sleeve hole 11 is formed in the milling cutter sleeve, the central axis of the milling cutter sleeve hole coincides with the central axis of the milling cutter sleeve, an opening is formed in the milling cutter sleeve hole on one end face of the milling cutter sleeve, and a drill bit penetrates into the milling cutter sleeve hole of the milling cutter sleeve through the opening.
The milling cutter trepanning forms an annular opening shape on the milling cutter sleeve end face, a milling block 12 is arranged on the end face of the milling cutter sleeve with the opening, the milling block is arranged on the annular structure of the end face, and the milling block extends from the end face to the direction far away from the milling cutter sleeve. The milling block is of a block structure, the milling cutter sleeve is made of alloy tool steel, high-speed steel, hard alloy or superhard cutter material, the milling block is also made of alloy tool steel, high-speed steel, hard alloy or superhard cutter material, and the milling block and the milling cutter sleeve are made of the same material. In some embodiments, the milling block and the milling cutter sleeve are of an integrally formed structure.
And a threaded hole 13 is formed in the side wall of the milling cutter sleeve, the threaded hole is communicated with the milling cutter sleeve hole, and the central axis of the threaded hole is perpendicular to the central axis of the milling cutter sleeve hole. The fixing piece is provided with external threads, the external threads on the fixing piece are matched with the threaded hole of the milling cutter sleeve, and the fixing piece is arranged in the threaded hole in a rotating mode and used for fixing a drill bit.
The cutting end 21 of drill bit comprises many heliciform main cutting edges, and the diameter of the cutting end maximum diameter of drill bit and stiff end all is less than the aperture in milling cutter trepanning, and in milling cutter trepanning of milling cutter cover was located to the stiff end 22 cover of drill bit, the cutting end protrusion milling cutter trepanning of drill bit, perhaps in milling cutter trepanning of milling cutter cover was located to stiff end and cutting end all cover of drill bit, the cutting end incomplete protrusion milling cutter trepanning of drill bit.
The fixed end of the drill bit is of a cylindrical structure, and a longitudinal cutting plane 23 is arranged on the side face of the fixed end of the drill bit. The longitudinal cutting plane is arranged on the longitudinal cutting plane of the fixed end of the drill bit, so that the fixing piece and the longitudinal cutting plane of the drill bit are not easy to slip.
