Technical field
The present invention relates to a kind of main axis of dilatation take-up, refer to especially a kind of main axis of dilatation take-up of wire drawing machine.
Background technology
Main axis of dilatation take-up in the high-quality sound wire wire drawing machine of current tradition, mechanism as shown in Figure 1, main axis of dilatation fixedly drum is by tighting a bolt 4 turnover, control the turnover of expansion key 2 on rotating shaft 3, expansion key 2 coordinates with rotating shaft 3 underrun inclined-planes, when the 43 expansion keys while being screwed into that tight a bolt make progress along hypotenuse simultaneously, the key distending that now expands, i.e. fixing drum; This mechanism drum is fixing to be fixed by the swelling of expansion key, little with drum endoporus contact area, be not easy fixedly drum, and contact area little easy wearing and tearing key, the service life that makes it key is not long, a period of time just needs to change, and this key processing and how cumbersomely change, and this wire-rewinding structure has just restricted the production efficiency of wire drawing machine.
Summary of the invention
Technical problem to be solved by this invention is: a kind of main axis of dilatation take-up of wire drawing machine is provided, and this main axis of dilatation take-up can strengthen the contact area with take-up reel, makes take-up reel fixing more firm, and the amount of reducing wear, increase the service life.
For solving the problems of the technologies described above, technical scheme of the present invention is: the main axis of dilatation take-up of wire drawing machine, comprise rotating shaft and take-up reel, also comprise expansion sleeve, hold out against tapered sleeve and hold out against nut, described rotating shaft comprises frustum section and the cylindrical section be connected with the miner diameter end of this frustum of a cone, described expansion sleeve is set on rotating shaft, take-up reel is installed on expansion sleeve, and the two ends of this expansion sleeve are provided with inner conical surface, wherein the inner conical surface of an end coordinates with the frustum section, describedly hold out against on the cylindrical section that tapered sleeve is set in rotating shaft and be positioned at expansion sleeve, the described periphery that holds out against tapered sleeve is provided with the male cone (strobilus masculinus) coordinated with the inner conical surface of the expansion sleeve other end, described holding out against between tapered sleeve and rotating shaft is pressed with axial back-moving spring in advance, describedly hold out against the end locking that nut is installed on cylindrical section and hold out against tapered sleeve.
As a kind of preferred scheme, described expansion sleeve comprises cylindrical tube, the two ends of this cylindrical tube are provided with inner conical surface, described cylindrical tube arranges some first kind grooves and Second Type groove, the degree of depth of this first kind groove and Second Type groove all is through to the inner core face of cylindrical drum from cylindrical tube urceolus face, the length of described first kind groove is extended to the second end and is not connected the second end by the first end of cylindrical tube, the length of described Second Type groove is extended to first end and is not connected first end by the second end of cylindrical tube, mutually stagger circle spacing of first kind groove and Second Type groove arranges.
As a kind of preferred scheme, the cylindrical tube of described expansion sleeve is provided with at least one ring shape mounting groove, and in this annular mounting groove, banding tightens up back-moving spring.
As a kind of preferred scheme, the number of described annular mounting groove is 3 and disposed at equal distance.
After having adopted technique scheme, effect of the present invention is: expansion sleeve one end of the present invention coordinates with the frustum face of rotating shaft, the other end coordinates with the male cone (strobilus masculinus) that holds out against tapered sleeve, thereby make the expansion sleeve tensioning, and the outer peripheral face of expansion sleeve and take-up reel contact-making surface are large, expansion sleeve is not easy to wear, and fixed effect, and then increases the service life.
Again because described expansion sleeve comprises cylindrical tube, the two ends of this cylindrical tube are provided with inner conical surface, described cylindrical tube arranges some first kind grooves and Second Type groove, the degree of depth of this first kind groove and Second Type groove all is through to the inner core face of cylindrical drum from cylindrical tube urceolus face, the length of described first kind groove is extended to the second end and is not connected the second end by the first end of cylindrical tube, the length of described Second Type groove is extended to first end and is not connected first end by the second end of cylindrical tube, mutually stagger circle spacing of first kind groove and Second Type groove arranges, therefore, this expansion sleeve rational in infrastructure, easily realize spreading and tighten up.
Cylindrical tube due to described expansion sleeve is provided with at least one ring shape mounting groove again, and in this annular mounting groove, banding tightens up back-moving spring, therefore, the spreading of this expansion sleeve is realized by holding out against tapered sleeve, shrink and driven by the retracted for clearance spring force, like this, the action of expansion sleeve is more reliable.
