In figure, 1 is cutter head, and 2 is cutter hub, and 3 is square section, and 4 is circle segments, and 5 is cylindrical protrusions, and 6 is nut, and 7 is installing hole, and 8 is bolt hole, and 9 is tapped blind hole, and 10 is bolt, and 11 is stopper slot, 12 is spacing preiection, and 13 is packing ring.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1, 2, a kind of cutter of replaceable cutter hub, comprise handle of a knife, cutter head 1, cutter hub 2, it is circular circle segments 4 that described handle of a knife is divided into cross section to be square square section 3 and cross section, the end of circle segments is provided with the cylindrical protrusions 5 with circle segments coaxial line, the sidewall of cylindrical protrusions is provided with external screw thread, described cutter head is annular, cutter head is locked in cylindrical protrusions by nut 6, the lateral wall of cutter head is provided with some installing holes 7 of radial direction setting and the bolt hole 8 with installing hole vertical connection, described cutter hub is arranged in installing hole, the sidewall of cutter hub is provided with the tapped blind hole 9 with bolt hole coaxial line, cutter hub is fixedly mounted in installing hole by bolt 10.
Select corresponding cutter hub according to processing request, cutter hub is placed in installing hole, is tightly locked in installing hole by cutter hub by the bolt in bolt hole.The replacing of cutter hub without the need to handle of a knife is also disassembled, the axiality of the processing both ensured, time saving and energy saving again, increase work efficiency.
Cutter hub can be lathe tool etc.The tail end of cutter hub is provided with the construction section adapted with installing hole, and above-mentioned tapped blind hole is just arranged on construction section.
Handle of a knife is divided into direction section and circle segments, and the setting of direction section is convenient to cutter and is clamped, and after cutter is clamped, cutter can be limited by firmly radial.
The sidewall of described cylindrical protrusions is provided with axial limiting groove 11, and the madial wall of described cutter head is provided with the spacing preiection 12 that axial limiting groove matches.Spacing preiection is placed in stopper slot, realizes spacing to the radial direction of cutter head by stopper slot and spacing preiection.Cutter head in cylindrical protrusions, realizes axial limiting to cutter head by circle segments and nut by nut locking.Cutter head is firmly fixed thus on handle of a knife.
Also or, the internal thread that the external screw thread that the madial wall of described cutter head is provided with cylindrical protrusions matches.Cutter head is threaded with cylindrical protrusions, strengthens the connection between cutter head and cylindrical protrusions.Cutter head in cylindrical protrusions, realizes axial limiting to cutter head by circle segments and nut by nut locking.Cutter head is firmly fixed thus on handle of a knife.
The pore size of described installing hole is not etc.Installing hole pore size etc. can not be convenient to the installation of the cutter hub of different-diameter.
Be provided with packing ring 13 between described nut and cutter head, arranging of packing ring can improve the coupling mechanism force of nut to cutter head.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
