Description

A kind of turning tool of slender axles
Technical field
This utility model relates to Technology for Turning Machining field, the turning tool of a kind of slender axles.
Background technology
Carry out slender axles (length diameter ratio is more than 25) on lathe adds man-hour, due to slender axles poor rigidity, easily occurs deformation, bending etc. during turning.In prior art, generally use the mode on folder one top or use follow-rest to do the mode of auxiliary support to complete the processing of slender axles.But, for the slender axles that draw ratio is bigger, the mode effect on folder one top is the most bad, and if slender axles periphery is not the face of cylinder, also cannot use follow-rest, these methods have limitation.
Summary of the invention
Technical purpose of the present utility model is to provide the turning tool of a kind of slender axles, solves the problem that traditional elongate axle turning mode has limitation, processing effect difference.
Concrete technical scheme of the present utility model is as follows: the turning tool of a kind of slender axles, including lathe chuck, also include mandrel clamping device, described mandrel clamping device includes the first core sleeve and the second core sleeve being connected with described first core sleeve, described first core sleeve is provided with first core sleeve's leading portion and second core sleeve's back segment, described second core sleeve is provided with second core sleeve's leading portion and second core sleeve's back segment, being connected by bearing holder (housing, cover) between described first core sleeve's back segment with described second core sleeve's leading portion, described first core sleeve's leading portion is provided with mandrel clamping sleeve.
As preferably, described first core sleeve's leading portion is provided with external thread section, and described mandrel clamping sleeve is placed in described first core sleeve's leading portion, and described external thread section is bolted with the thread bush for fixing described mandrel clamping sleeve.
As preferably, described mandrel clamping sleeve is provided with annular slot, and described thread bush is provided with the snap ring for matching with described annular slot;The part being positioned at described annular slot side of described mandrel clamping sleeve is placed on outside described external thread section, and the part being positioned at described annular slot opposite side is built in described external thread section.
As preferably, in described bearing holder (housing, cover), it is provided with deep groove ball bearing and thrust ball bearing.
As preferably, described deep groove ball bearing is provided with 2 groups, and described thrust ball bearing is provided with 1 group.
Described second core sleeve's back segment is for external fixing conical section.
Technological merit of the present utility model is the turning tool simple in construction of described slender axles, easy to use, and the suitability is strong, and turnery processing is effective, improves work efficiency and quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the partial structurtes schematic diagram of this utility model embodiment;
The each toponym numbering correspondence in figure is respectively as follows: 1-lathe chuck, 2-the first core sleeve, 21-the first core sleeve leading portion, 211-external thread section, 22-the second core sleeve back segment, 3-the second core sleeve, 31-the second core sleeve leading portion, 32-the second core sleeve back segment, 4-bearing holder (housing, cover), 41-deep groove ball bearing, 42-thrust ball bearing, 5-mandrel clamping sleeve, 51-annular slot, 6-thread bush, 61-snap ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail:
See Fig. 1, Fig. 2, a kind of turning tool of slender axles, including lathe chuck 1, also include mandrel clamping device, mandrel clamping device includes the first core sleeve 2 and the second core sleeve 3 being connected with the first core sleeve 2, first core sleeve 2 is provided with the first core sleeve's leading portion 21 and second core sleeve's back segment 22, second core sleeve 3 is provided with the second core sleeve's leading portion 31 and second core sleeve's back segment 32, being connected by bearing holder (housing, cover) 4 between first core sleeve's back segment 22 with second core sleeve's leading portion 31, first core sleeve's leading portion 21 is provided with mandrel clamping sleeve 5.Second core sleeve's back segment 22 is for external fixing conical section.Deep groove ball bearing 41 and thrust ball bearing 42 it is provided with in bearing holder (housing, cover) 4.Deep groove ball bearing 41 is provided with 2 groups, and thrust ball bearing 42 is provided with 1 group.
First core sleeve's leading portion 21 is provided with external thread section 211, and mandrel clamping sleeve 5 is placed in first core sleeve's leading portion 21, and external thread section 211 is bolted with the thread bush 6 for fixed central spindle's clamping sleeve 5.Mandrel clamping sleeve 5 is provided with annular slot 51, and thread bush 6 is provided with the snap ring 61 for matching with annular slot 51;The part being positioned at annular slot 51 side of mandrel clamping sleeve 5 is placed on outside external thread section 211, and the part being positioned at annular slot 51 opposite side is built in external thread section 211.
As a example by the core print of cold-rolling mill, specific process is: clamping adjusts, ensure that mandrel clamping device and lathe chuck 1 spacing are 150-200mm, putting in lathe chuck by one end of core print, the other end is put in mandrel clamping device, clamps lathe chuck 1 and mandrel clamping device after centering periphery, thread bush 6 is relied on to be fixed by mandrel clamping sleeve 5, core print adds and the first core sleeve 2 and the second core sleeve 3 is rotated against by bearing holder (housing, cover) 4 man-hour, then starts turning, stays polished amount.After complete one section of car, unclamping the thread bush 6 of lathe chuck 1 and mandrel clamping device, reach core print continues turning, until whole core print turning completes, then polishes away and connect tool marks.
