The three-axle linkage boring bar for taper holes has the advantages that the three-axle linkage boring bar is clever in design and reasonable in structure, can be used for machining taper holes with different specifications and special tapers.
Description
Technical field
The utility model relates to a kind of machining apparatus, the especially a kind of three-shaft linkage taper hole boring bar that can realize the special tapering taper hole processing of multiple different size.
Background technology
In field of machining; Sometimes need carry out the taper hole processing of special tapering; The taper hole that requires like taperings such as 1:12,1:15 and 1:20 adds man-hour, need on boring bar, according to certain angle the cutter head jockey be installed, and these devices only can be processed the taper hole that a certain specific taper requires; Therefore each tapering requires just corresponding cutter head jockey; Complex manufacturing technology, with high costs, therefore need a kind of boring bar of can be fast, between the taper hole that various taperings require, changing neatly now.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, and it is ingenious, rational in infrastructure to propose a kind of design, can realize the three-shaft linkage taper hole boring bar of the special tapering taper hole processing of multiple different size.
The technical solution of the utility model is: a kind of three-shaft linkage taper hole boring bar; Comprise boring bar body 1; It is characterized in that: in boring bar body 1, axially be provided with slide block and drive leading screw 2 and axial bit feed shaft 3; Slide block drives leading screw 2 and is threaded with slide block 4 on being slidingly connected at boring bar body 1; Axial bit feed shaft 3 is provided with first bevel gear 5 that can endwisely slip and rotate thereupon with respect to axial bit feed shaft 3, and the bottom of the radially leading screw 6 of bearings in slide block 4 is provided with second bevel gear 7 that is meshed with first bevel gear 5, and screw 8 has been threaded on leading screw 6 radially; Screw 8 is connected with radially tool feeding axles 9 in being actively socketed on slide block 4, drives at slide block and also is provided with main transmission reduction box 10 and differential reducing mechanism 11 between leading screw 2 and axial bit feed shaft 3 and the drive unit.
The utility model is compared with prior art, has following advantage
The taper hole boring bar of this kind of version; Its compact conformation, rationally distributed, design ingenious; It utilizes differential reducing mechanism; Two different motions are resolved in main motion, utilize the mode of three-shaft linkage to realize axially-movable and the radial feed of cutter head on boring bar, can be through the axially-movable of restriction cutter head and the tapering that radial motion speed realizes required processing taper hole.Utilize it can realize the processing of multiple different tapering taper holes, flexible, with low cost, therefore we can say that this boring bar has possessed multiple advantage, very help in field of machining, applying, its market prospects are comparatively wide.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
The specific embodiment
Below with the specific embodiment of accompanying drawings the utility model.Like Fig. 1, shown in Figure 2: a kind of three-shaft linkage taper hole boring bar; Comprise boring bar body 1; Boring bar body 1 links to each other with drive unit with differential reducing mechanism 11 through main transmission reduction box 10, and differential reducing mechanism 11 is decomposed into the moment of torsion output of two different rotating speeds with the input of the moment of torsion of drive unit, and these two moments of torsion outputs are separately positioned on boring bar body 1 inner driving sliding block and drive leading screw 2 and axial bit feed shaft 3; Wherein slide block driving leading screw 2 is threaded with slide block 4; And slide block 4 is slidingly connected in the boring bar body 1, and axial bit feed shaft 3 is provided with its first bevel gear 5 that endwisely slips and rotate thereupon relatively, and the bottom of the radially leading screw 6 of bearings in slide block 4 is provided with second bevel gear 7; And first bevel gear 5 and second bevel gear 7 are meshing with each other; The screw 8 that on leading screw 6 radially, has been threaded, screw 8 links to each other with tool feeding axle 9 radially, and radially tool feeding axle 9 can stretch in slide block 4;
The course of work of the three-shaft linkage taper hole boring bar of the utility model embodiment is following: at first cutter head is connected the radially end of tool feeding axle 9; Start drive unit then; Drive unit with moment of torsion through among the main transmission reduction box 10 input differential reducing mechanisms 11; Differential reducing mechanism 11 is decomposed into this moment of torsion input the moment of torsion output of two different rotating speeds; And be sent to slide block respectively and drive leading screw 2 and axial bit feed shaft 3, the rotating speed of these two moments of torsion outputs and the ratio of the rotating speed of total input can be according to actual needs, utilize main transmission reduction box 10 and differential reducing mechanism 11 among pitch wheel obtain; In said process, the rotation section branch of differential reducing mechanism 11 rotates with boring bar body 1, is arranged on the rotation that boring bar body 1 inner slide block drives leading screw 2 and the relative boring bar of axial bit feed shaft 3 generations simultaneously;
Slide block drives in leading screw 2 rotating process, and the slide block 4 that is threaded with it can drive the axially-movable of leading screw 2 along slide block; In axial bit feed shaft 3 rotating process; First bevel gear 5 on it can drive second bevel gear 7 and rotate; The radially leading screw 6 that links to each other with second bevel gear 7 also rotates thereupon; At this moment, being threaded in screw on the leading screw 6 radially just can drive the radially tool feeding axle 9 that is attached thereto and do radial motion; The rotation (rotation of cutter head) of boring bar body 1 itself is added in the combination of above-mentioned two motions (axially-movable of slide block 4 and the radially radial motion of tool feeding axle 9), just can realize the processing of some special tapering taper hole.
