Abstract
Anti -drop output shaft, including output shaft body and connecting axle, the one end of output shaft body is equipped with the external screw thread, and the both ends of connecting axle be hollow sleeve, are equipped with the internal thread in the one end of connecting axle, and external screw thread and interior screw -thread fit, connecting axle are equipped with the inside plug that is equipped with the cone type of internal screw thread one end, and the jack is seted up to the one end that is equipped with the external screw thread of output shaft body, and the plug is pegged graft with the jack and is cooperated. The utility model discloses in adopting, adopting screw -thread fit between output shaft body and the connecting axle, also cooperating through the frictional force between plug and the jack simultaneously, dual mode guarantee complex stability effectively avoids the output shaft body to drop. Output shaft body easy dismounting is convenient for change as required.
Description
Technical field
This utility model belongs to field of machine tool equipment, specifically a kind of slip-off preventing output shaft.
Background technology
Working shaft does not has nut to pass through pressure and frictional force coordinates with output shaft, and loosening easily occurs in this fit system, and of long duration will result in comes off, and there is potential safety hazard.
Utility model content
This utility model provides a kind of slip-off preventing output shaft, in order to solve defect of the prior art.
This utility model is achieved by the following technical programs:
Slip-off preventing output shaft, including output shaft body and connecting shaft, one end of output shaft body is provided with external screw thread, the two ends of connecting shaft are the sleeve of hollow, being provided with female thread, external screw thread and screw-internal thread fit in one end of connecting shaft, connecting shaft sets and is provided with cone-shaped plug inside female one end, jack is offered in the externally threaded one end that is provided with of output shaft body, and plug coordinates with jack grafting.
Slip-off preventing output shaft as above, described connecting shaft sets female end and is provided with coordinating block, and the outside of output shaft body is provided with mating groove, coordinating block coordinates with mating groove, and coordinating block is offered through hole, is provided with screw in through hole, being provided with screw in mating groove, screw coordinates with screw.
Slip-off preventing output shaft as above, the periphery of described plug is provided with one layer of skid resistant course.
The utility model has the advantages that: during this utility model is adopted, using threaded engagement between output shaft body and connecting shaft, simultaneously also by the friction fit between plug and jack, dual mode ensures the stability coordinated, is prevented effectively from output shaft body and comes off.Output shaft body easy accessibility, it is simple to change as required.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；Fig. 2 is the sectional view of the line A-A along Fig. 1.
Figure number marks: 1 output shaft body, 2 mating grooves, 3 connecting shafts, 4 coordinating blocks, 5 screws, 6 screws, 7 through holes, 8 set letters, 9 external screw threads, 10 female threads, 11 plugs, 12 skid resistant courses, 13 jacks.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Slip-off preventing output shaft, as shown in the figure, including output shaft body 1 and connecting shaft 3, one end of output shaft body 1 is provided with external screw thread 9, and the two ends of connecting shaft 3 are the sleeve 8 of hollow, are provided with female thread 10 in one end of connecting shaft 3, external screw thread 9 coordinates with female thread 10, connecting shaft 3 is provided with inside one end of female thread 10 and is provided with cone-shaped plug 11, and jack 13 is offered in one end being provided with external screw thread 9 of output shaft body 1, and plug 11 coordinates with jack 13 grafting.During this utility model is adopted, using threaded engagement between output shaft body 1 and connecting shaft 3, simultaneously also by the friction fit between plug 11 and jack 13, dual mode ensures the stability coordinated, is prevented effectively from output shaft body 1 and comes off.Output shaft body 1 easy accessibility, it is simple to change as required.
Specifically, in order to improve the tightness coordinated of output shaft body 1 and connecting shaft 3, connecting shaft 3 described in the present embodiment is provided with the end of female thread 10 and is provided with coordinating block 4, the outside of output shaft body 1 is provided with mating groove 2, coordinating block 4 coordinates with mating groove 2, coordinating block 4 is offered through hole 7, is provided with screw 5 in through hole 7, being provided with screw 6 in mating groove 2, screw 5 coordinates with screw 6.Output shaft body 1 and connecting shaft 3, on the basis of threaded engagement, are laterally being fixed further through screw 5, such that it is able to avoid the generation of dropping situations further, are effectively improved and connect the steadiness coordinated.
Concrete, in order to improve the stability that plug 11 coordinates with jack 13 further, the periphery of the plug 11 described in the present embodiment is provided with one layer of skid resistant course 12.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
