A kind of auxiliary device for pressing wheel axle of planet carrier
Technical field
The present invention relates to small-sized planet carrier and make frock, particularly a kind of auxiliary device for pressing wheel axle of planet carrier.
Background technology
In some small mechanical products, need to use small-sized planet carrier, multistage planet frame particularly, because part is too small, wheel axle of planet carrier is processed very inconvenient with planet carrier, and be difficult to reach technological requirement, therefore mostly planet carrier is separated processing with wheel shaft, and then wheel shaft is fixed on the planet carrier.When fixing wheel shaft, wheel shaft and planet carrier end face are required certain perpendicularity, therefore will avoid in the wheel shaft fixation procedure, may occurring the factor that makes wheel shaft crooked, make the planet carrier finished product of producing at last satisfy technological requirement.
Summary of the invention
Problem to be solved by this invention just provides a kind of level auxiliary device for pressing wheel axle of planet carrier simple in structure, easy to use, guarantee the perpendicularity of the relative planet carrier end face of wheel shaft, process at one time, reduce workman's operation easier, enhance productivity, improve the quality of products.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of auxiliary device for pressing wheel axle of planet carrier, it is characterized in that: comprise holder, be provided with the unthreaded hole that installs the planet carrier rotating shaft in the described holder, above unthreaded hole, be provided with the mounting groove of laying the wheel axle of planet carrier fixed disk, on the bottom face of mounting groove, be provided with the location structure of location planet carrier upper whorl axial fixing hole, in mounting groove, also be provided with and cooperate the positioning disk of locating wheel shaft with location structure.
Further, the bottom face of described mounting groove is horizontally disposed with, described location structure comprises the locating hole at least one bottom face that vertically is located at mounting groove and is located at the locating shaft that moves up and down in the locating hole, described locating shaft is corresponding with planet carrier upper whorl axial fixing hole, also is provided with the elastic component that locating shaft is upwards pushed away be positioned at locating shaft in locating hole below.
Further, described locating shaft and planet carrier upper whorl axial fixing hole matched in clearance.
Further, described locating shaft exposes the thickness of the height of mounting groove bottom face above the wheel axle of planet carrier fixed disk under the elastic component nature.
Further, the lower end of described locating hole is provided with screw thread, and described elastic component is positioned in the locating hole and with the bottom of locating shaft by screw and threaded engagement and is connected, and described elastic component is spring or elastic sheet metal.
Further, described positioning disk cooperates with mounting groove, the bottom face of described positioning disk is horizontally disposed with, described positioning disk is provided with the try to get to the heart of a matter through hole of end face of perpendicular positioning, and described through hole is corresponding with planet carrier upper whorl axial fixing hole and diameter through hole is bigger 0.2~0.3 millimeter than the diameter of planet carrier upper whorl axial fixing hole.
Further, described locating shaft cooperates with via clearance on the positioning disk.
After adopting technique scheme, the present invention has following advantage: by mounting groove and locating shaft location planet carrier, guarantee accurately location, assist the perpendicularity that guarantees wheel shaft by positioning disk again, simple to operation, not only reduce workman's operation easier, more improved production efficiency and product quality.

The specific embodiment
The structural representation of an embodiment of the present invention shown in Fig. 1 to 5, a kind of auxiliary device for pressing wheel axle of planet carrier, comprise a holder 1, be provided with the unthreaded hole 11 that installs planet carrier rotating shaft 81 in the holder 1, above unthreaded hole 11, be provided with the mounting groove 12 of laying wheel axle of planet carrier fixed disk 82, the bottom face of mounting groove 12 is horizontally disposed with, on the bottom face of mounting groove 12, vertically be provided with locating hole 13, in locating hole 13, be provided with the locating shaft 3 that moves up and down, locating shaft 3 is corresponding with planet carrier upper whorl axial fixing hole 83, also be provided with the elastic component 4 that locating shaft 3 is upwards pushed away be positioned at locating shaft 3 in locating hole 13 below, locating shaft 3 and planet carrier upper whorl axial fixing hole 83 matched in clearance and the height that locating shaft 3 exposes mounting groove 12 bottom faces under elastic component 4 natures surpass the thickness of wheel axle of planet carrier fixed disk 82; In mounting groove 12, also be provided with in addition and cooperate the positioning disk 2 of locating wheel shaft 84 with locating shaft 3, positioning disk 2 cooperates with mounting groove 12, the bottom face of positioning disk 2 is horizontally disposed with, positioning disk 2 is provided with the try to get to the heart of a matter through hole 21 of end face of perpendicular positioning, the wheel shaft fixing hole 83 of through hole 21 and planet carrier is corresponding and diameter through hole 21 is bigger 0.2~0.3 millimeter than the diameter of planet carrier upper whorl axial fixing hole 83, through hole 21 matched in clearance on locating shaft 3 and the positioning disk 2.
In the foregoing description, locating shaft 3 lower ends are provided with step I31, be provided with in the locating hole 13 to cooperate and be provided with step II132 with step I31, locating shaft 3 is against step II132 by step I31 and goes up spacing, the lower end of locating hole 13 is provided with screw thread 131, elastic component 4 cooperates to be positioned in the locating hole 13 and with the bottom of locating shaft 3 with screw thread 131 by screw 5 and is connected, and elastic component 4 is spring or elastic sheet metal; The planet carrier of wheel shaft to be pressed is put into holder, locating shaft is installed in the wheel shaft fixing hole on the planet carrier, the location is convenient, again positioning disk is put on the planet carrier, the locating shaft that exposes the wheel axle of planet carrier fixed disk is installed in one of them through hole of positioning disk, positioning disk is fixed by mounting groove and locating shaft like this, and the through hole that again wheel shaft is passed positioning disk is pressed in the wheel shaft fixing hole of planet carrier.By mounting groove and locating shaft location planet carrier, guarantee accurately location like this, assist the perpendicularity that guarantees wheel shaft by positioning disk again, simple to operation, not only reduce workman's operation easier, more improved production efficiency and product quality; After the wheel shaft compacting was finished, because locating shaft is moved up by the thrust of elastic component, and planet carrier upper whorl axial fixing hole had been pressed into wheel shaft, so locating shaft can be with wheel axle of planet carrier fixed disk release mounting groove, and therefore the planet carrier that machines is easy to take out.
Figure of description of the present invention is depicted as III level auxiliary device for pressing wheel axle of planet carrier, at the above wheel axle of planet carrier compacting of II level or III level can be according to the present invention to the number of openings on the positioning disk and the position is set improves and get final product.Planet carrier upper whorl axial fixing hole carries out secondary process for circular or the non-circular apparatus of the present invention of all can using.
Except that above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
