Description
Technical field
The utility model relates to a kind of metal cutting tool adjusting device, and specifically, the utility model relates to radially micromatic setting of a kind of boring cutter.
Background technology
The normal endoporus that adopts boring technology fine finishining case, shell class part in the machinery manufacturing industry, boring cutter radially installation site determines by the diameter of bore hole.The boring cutter of prior art radially is equipped with the location and can regulates two kinds of versions.The boring cutter of described two kinds of installation forms can both be realized accurate boring processing, but all comes with some shortcomings.Particularly the boring cutter radiai adjustment difficulty of location and installation is big, and the operator is required height, and its position must and be adjusted and could finally determine through the measurer repeated measurement.Although but the adjustable structure radiai adjustment, because of having only single threaded adjusting in the structure, boring cutter radial displacement value is bigger than normal, is difficult for realizing radially accurately fine setting of boring cutter.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of simple in structurely, easy to operate, can realize the radially differential micromatic setting of accurately regulating of boring cutter.
The utility model is achieved through the following technical solutions technical goal.
The radially differential micromatic setting of boring cutter, it is made of boring cutter, screw, differential lever, positioning sleeve and boring cutter bar.Described boring cutter bar end is provided with radial direction through hole boring cutter and positioning sleeve is installed, with the boring cutter of radial direction through hole matched in clearance by the screw latched position, the positioning sleeve that matches with radial direction through hole is by another screw fixed position.Described boring cutter tail end middle part and positioning sleeve end face middle part are provided with the axial screw of different-diameter.Its improvements are: described differential lever two thread segments cooperate with the positioning sleeve of boring cutter and fixed-site movably respectively and constitute difference structure.
In the said structure, reserve displacement interval between boring cutter of installing in the boring cutter bar radial direction through hole and the positioning sleeve, its spacing is greater than bore hole surplus 1～2mm.The boring cutter of removable position and the positioning sleeve of fixed-site by two ends have coaxial, be connected respectively with the differential lever of rotation direction screw thread, utilize the pitch difference of its different nominal dimension screw threads, realize that the rotation of differential lever directly changes into the straight-line displacement of boring cutter relative positioning cover.Differential lever revolves and turns around, and boring cutter relative positioning cover straight-line displacement distance equals the pitch difference of differential lever two ends screw thread.Positioning sleeve is provided with the five equilibrium groove towards the screw periphery of outer face, as differential lever fine setting coordinate.
The utility model compared with prior art has following good effect:
1, differential differential tuning is simple in structure, making is easy;
2, the actual straight-line displacement amount of differential generation is little, easily realizes accurately fine setting;
3, differential differential tuning is convenient, and the location, position is reliable.
Description of drawings
Fig. 1 is the utility model structural profile schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is Fig. 2 side view.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, utility model is described further.
The radially differential micromatic setting of boring cutter shown in Figure 1, it is made of boring cutter 1, screw 2, differential lever 3, positioning sleeve 4 and boring cutter 5 bars.Described boring cutter bar 5 ends are provided with radial direction through hole boring cutter 1 and positioning sleeve 4 are installed, the boring cutter 1 that cooperates with via clearance and and the positioning sleeve 4 of fixed-site between reserve displacement interval, its spacing is greater than bore hole surplus 2mm.Boring cutter 1 tail end middle part and positioning sleeve 4 end faces middle part are provided with the axial screw of different-diameter, differential lever 3 is with coaxial, the same rotation direction in two ends, but the screw thread of different-diameter cooperates with boring cutter 1, positioning sleeve 4 respectively, the uniform radially groove 4.1 of positioning sleeve 4 outer face screw peripheries, this end face exceeds not protrude boring cutter bar 5, and fixing by screw 2.Straight-line displacement takes place in the positioning sleeve 4 with respect to fixed-site during differential lever 3 rotations, and straight-line displacement also takes place the boring cutter 1 of removable position, and its displacement is relevant with the pitch of the screw thread that matches, and direction of displacement is opposite.In the present embodiment, the screw thread that differential lever 3 matches with positioning sleeve 4 is M8 * 1.25mm, the screw thread that differential lever 3 matches with boring cutter 1 is M6 * 1.0mm, when differential lever 3 dextrorotations are circled, differential lever 3 with respect to positioning sleeve 4 forward straight line move 1.25mm, and another section screw thread of rotation makes the boring cutter 1 that the matches 1.0mm that contracts in the straight line backward simultaneously, and the difference that both straight lines move is 0.25mm.Differential lever 3 is rotated counterclockwise a week, then produces the respective opposed straight-line displacement, and its difference is still 0.25mm.Positioning sleeve 4 outer face screw peripheries are all established radially 20 of graduation marks, and differential 0.25/20=0.0125mm then takes place differential lever 3 every rotation one lattice.So small distance is regulated and is convenient to realize accurate fine setting, and the boring cutter 1 that fine setting puts in place is by 2 lockings of another screw, and its location, boring cutter position is reliable, bore hole precision height.
