Abstract
The utility model discloses a directly-modulated fine boring tool, mainly comprising a tool body, a tool bearer, a positioning device and a fine adjustment screw, wherein a groove for installation of tool bearer is opened in the center of the tool body; a transversal positioning hole corresponding to the groove is made on the tool body, and the tool bearer has a corresponding positioning hole; the tool body and the tool bearer are fixed by the positioning device of the positioning holes; crew holes are provided on lower ends of the tool body and the tool bearer, and the fine adjustment screw is inserted in the two screw holes so that the blade is fixed on lower end of the tool bearer; middle part of the fine adjustment screw is conical; the positioning device is a positioning pin or bolt; in practical use, place the tool bear into the groove in the tool body before fixing the tool body and the tool bearer with the positioning device; then insert the fine adjustment screw through the screw holes; when adjusting the tool, turn the fine adjustment screw so that the tool bearer undergoes elastic deformation to take slight size changes diametrically for adjustment of tool. Compared with conventionally tools, the utility model has a simple structure, with better maintainability, high processing efficiency and excellent stability.
Description
Technical field
The utility model relates to used cutter on a kind of industrial lathe, refers to a kind of straight mode fine boring cutter especially.
Background technology
Adjustable boring tool in the past is a roughing tool, it mainly is to be used for the bigger workpiece in heavy boring aperture, its ratio of precision is lower, there was the dealer to invent afterwards again as Chinese patent CN200420054045.9, it has solved the low problem of precision, but its structure is relatively complicated, so its maintenanceability is just poor, and working (machining) efficiency is low, poor stability.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and maintenanceability is good, and the good straight mode fine boring cutter of working (machining) efficiency high stability.
For achieving the above object, solution of the present utility model is: a kind of straight mode fine boring cutter, it is characterized in that: it mainly comprises cutter body, edge bearing, positioner and fine setting screw, be provided with the groove of installing edge bearing in the middle of the cutter body, the cutter body is corresponding with groove laterally is provided with locating hole, on the edge bearing also correspondence be provided with locating hole, cutter body and edge bearing are fixed by the positioner of being located at locating hole; The lower end of cutter body and edge bearing is provided with screw hole, and fine setting screw is arranged in these two screw holes successively, and blade is fixedly arranged on the edge bearing lower end; The fine setting screw stage casing is configured as taper.
Described positioner is an alignment pin.
Described positioner is a screw.
After adopting said structure, in use, earlier edge bearing is positioned in the groove of cutter body, again alignment pin or screw is passed the locating hole of cutter body and the locating hole of edge bearing successively, thereby, again fine setting screw is passed successively the screw hole of cutter body and the screw hole of edge bearing with cutter body and edge bearing location; When needs are adjusted the position of cutter, rotate fine setting screw up and down, utilize the difference of fine setting screw position and the taper setting in stage casing, make edge bearing generation strain, produce diametric microscale dimensions and change, therefore reach the purpose of adjusting cutter, compare with commonly using with novel, it is simple in structure, so its maintenanceability is just relatively good, and process the efficient height, good stability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an outside drawing of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of straight mode fine boring cutter, it mainly comprises cutter body 1, edge bearing 2, positioner 3 and fine setting screw 4, wherein:
Be provided with the groove 11 of installing edge bearing 2 in the middle of the cutter body 1, cutter body 1 and groove 11 are corresponding laterally is provided with locating hole 12, on the edge bearing 2 also correspondence be provided with locating hole 21, cutter body 1 is fixed by the positioner 3 of being located at locating hole 12,21 with edge bearing 2; Cutter body 1 is provided with screw hole 13,22 with the lower end of edge bearing 2, and fine setting screw 4 is arranged in these two screw holes 13,22 successively, and blade 5 is fixedly arranged on edge bearing 2 lower ends; Fine setting screw 4 stage casings are configured as taper.
Described positioner is alignment pin or screw.
In use, earlier edge bearing 2 is positioned in the groove 11 of cutter body 1, again alignment pin or screw 3 are passed the locating hole 12 of cutter body 1 and the locating hole 21 of edge bearing 2 successively, thereby, again fine setting screw 4 is passed successively the screw hole 13 of cutter body 1 and the screw hole 22 of edge bearing 2 with cutter body 1 and edge bearing 2 location; When needs are adjusted the position of cutter, rotate fine setting screw 4 up and down, utilize the difference of fine setting screw position and the taper setting in stage casing, make edge bearing 2 that strain take place, produce diametric microscale dimensions and change, therefore reach the purpose of adjusting cutter, compare with commonly using with novel, it is simple in structure, so its maintenanceability is just relatively good, and process the efficient height, good stability.
Claims (3)
