Abstract
The invention relates to a cutting tool with a replaceable tool body. The cutting tool comprises a shank, a tool bit and a tool body, wherein the shank is divided into a square segment with a square section and a circular segment with a circular section; a cylindrical bump coaxial with the circular segment is arranged at the end part of the circular segment; an external thread is formed on the sidewall of the cylindrical bump; the tool bit is shaped like a circular ring, and is locked on the cylindrical bump through a nut; a plurality of radial mounting holes and bolt holes perpendicularly communicated with the mounting holes are formed in the outer sidewall of the tool bit; the tool body is arranged in the corresponding mounting hole; threaded blind holes coaxial with the bolt holes are formed in the sidewall of the tool body; the tool body is fixedly arranged in the corresponding mounting hole through a bolt. According to the scheme, the tool bit is arranged, the tool body can be arranged on the tool bit, corresponding tool bodies can be arranged for cutting according to different cutting requirements, and when the tool body is replaced, the tool body can be directly replaced without disassembling the shank; the machining coaxiality of a workpiece is effectively ensured, time and labor are saved, and working efficiency is greatly improved.
Description
Technical field
The present invention relates to machine tool technical field, be specifically related to a kind of cutter of replaceable cutter hub.
Background technology
The processing of complex part usually needs to change different cutters, and cutter changing process comparatively bothers, and is difficult to after cutter changing ensure axiality, wastes time and energy, increases labour intensity, inefficiency.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of cutter of replaceable cutter hub.
Realize technical scheme of the present invention as follows:
A kind of cutter of replaceable cutter hub, comprise handle of a knife, cutter head, cutter hub, it is circular circle segments that described handle of a knife is divided into cross section to be square square section and cross section, the end of circle segments is provided with the cylindrical protrusions with circle segments coaxial line, the sidewall of cylindrical protrusions is provided with external screw thread, described cutter head is annular, cutter head by nut locking in cylindrical protrusions, the lateral wall of cutter head is provided with some installing holes of radial direction setting and the bolt hole 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 with bolt hole coaxial line, cutter hub is mounted by means of bolts in installing hole.
Further, the sidewall of described cylindrical protrusions is provided with axial limiting groove, and the madial wall of described cutter head is provided with the spacing preiection that axial limiting groove matches.
Further, the madial wall of described cutter head is provided with the internal thread matched with the external screw thread of cylindrical protrusions.
Further, the pore size of described installing hole is not etc.
Have employed above-mentioned scheme, by arranging cutter head, cutter head can install cutter hub, according to different cutting requirements, corresponding cutter hub can be installed and carry out machining, during tool changing, also without the need to dismantling handle of a knife, but directly change cutter hub, the present invention effectively ensure that the axiality of work pieces process, saves time and laborsaving, substantially increases operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 exploded view;
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 invention will be further described.
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 the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention 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 invention.
