Description
Technical field
The utility model relates to a kind of double-blade boring cutter groove syndeton, is especially applied to the double-blade boring cutter groove syndeton in machine tool field.
Background technology
The double-blade boring cutter that groove traditional at present connects is the groove of boring cutter body upper surface and the groove engagement of cutter head lower surface, is realized the contact completely of the flank of tooth by trip bolt.In working angles two cutter heads end face on there is certain interval, the cutting force moment of torsion of Tool in Cutting can only rely on groove transmitting torque, although the torque carrying capability of insection structure is comparatively strong, when cutting force change greatly, operating mode poor when, the integral rigidity of cutter can decline.Therefore also do not have a kind of connection firm in prior art, bearing capacity is strong, strengthens in load, and cutting force change greatly, can make the double-blade boring cutter groove syndeton of cutter entirety maintenance better rigidity when operating mode is poor.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of connection firm, bearing capacity is strong, strengthens in load, and cutting force change greatly, can make the double-blade boring cutter groove syndeton of cutter entirety maintenance better rigidity when operating mode is poor.
For the double-blade boring cutter groove syndeton adopted that solves the problem, comprise boring cutter body, upper cutter head and lower cutter head, described upper cutter head comprises radial end face and axial end, described lower cutter head comprises radial end face and axial end, the radial end face of described upper cutter head is connected by groove with the end face of boring cutter body, the radial end face of described lower cutter head is connected by groove with the end face of boring cutter body, and the axial end of described upper cutter head and the axial end of lower cutter head are fitted.
Further, the interstice coverage between the axial end of described upper cutter head and the axial end of lower cutter head is 0mm to 0.005mm.
Further, be also provided with securing member, upper cutter head and lower cutter head are fixedly connected on boring cutter body along the axial direction of boring cutter body by described securing member.
Further, described securing member is trip bolt.
Further, the groove that described boring cutter body is connected with upper cutter head and lower cutter head is equidistant groove.
The beneficial effects of the utility model are: the groove field of conjugate action is fitted completely, the end face of two cutter heads is also fitted completely to adopt securing member to realize, the cutter head crossing location and installation have more in working angles stable, support reliably, improve integral rigidity and the stability in use of cutter, larger cutting force and the processing of worse operating mode can be adapted to, more can meet the demand of client.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is right view of the present utility model;
Be labeled as in figure: boring cutter body 1, upper cutter head 2, lower cutter head 3, radial end face 4, axial end 5, trip bolt 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figures 1 and 2, double-blade boring cutter groove syndeton, comprise boring cutter body 1, upper cutter head 2 and lower cutter head 3, described upper cutter head 2 comprises radial end face 4 and axial end 5, described lower cutter head 3 comprises radial end face 4 and axial end 5, the radial end face 4 of described upper cutter head 2 is connected by groove with the end face of boring cutter body 1, the radial end face 4 of described lower cutter head 3 is connected by groove with the end face of boring cutter body 1, and the axial end 5 of described upper cutter head 2 is fitted with the axial end 5 of lower cutter head 3.Realize the engagement of groove and the mutual support of two cutter head end faces, effectively improve integral rigidity and the stability in use of cutter.
Gap between the axial end 5 of described upper cutter head 2 and the axial end 5 of lower cutter head 3 is scope 0mm to 0.005mm.The effect that axial end 5 is fitted when the clearance control of two axial ends 5 is in aforementioned range is better.
Also be provided with securing member, upper cutter head 2 and lower cutter head 3 are fixedly connected on boring cutter body 1 along the axial direction of boring cutter body 1 by described securing member.Upper cutter head 2 is connected with boring cutter body 1 under the securing member effect of exerting pressure with lower cutter head 3, make it groove and cutter head end face is jointly stressed, there is micro-elastic deformation in material, realize the engaging completely of the flank of tooth, the end face of upper cutter head 2 and lower cutter head 3 supports mutually, effectively improve stability and the rigidity of groove double-blade boring cutter.Securing member can adopt the securing member that trip bolt 6, bolt, stud etc. are mechanically conventional.
Described securing member is trip bolt 6.Adopt trip bolt 6 to connect, structure is simple, connects reliable, easy to assembly.Tapped through hole can be set on upper cutter head 2 and lower cutter head 3, boring cutter body 1 arranges tapped blind hole.
The groove that described boring cutter body 1 is connected with upper cutter head 2 and lower cutter head 3 is equidistant groove.Adopt equidistant groove that end face is more easily fitted.
