Model utility content
The purpose of this utility model is defect for prior art and deficiency, provide a kind of simple and reasonable, take up room less, the good axial positioning mechanism of locating effect.
For achieving the above object, the utility model is by the following technical solutions:
A kind of axial positioning mechanism described in the utility model, comprise suitable axle, axle sleeve and back-up ring, described axle is circumferentially provided with first circular groove suitable with described back-up ring, the bottom land of described first circular groove is provided with inclined hole, the inwall of described axle sleeve is provided with second circular groove corresponding with described first circular groove, the bottom land of described second circular groove is provided with the through hole matched with described inclined hole, described through hole runs through the outer wall of described axle sleeve, described back-up ring is surrounded between described first circular groove and described second circular groove, and one end of described back-up ring is arranged in described inclined hole, the other end of described back-up ring is arranged in described through hole.
Further, the cross section of described first circular groove, described second circular groove is semicircle.
Further, the joint of described through hole and described second circular groove is provided with crescent.
Further, described through hole is set to tapped hole, is provided with screw plug in described tapped hole.
The beneficial effects of the utility model are: the utility model preferably adopts copper wire back-up ring, during assembling, first axle is inserted in axle sleeve, until the first circular groove and the second circular groove position align, and make through hole aim at inclined hole position, then the front end of copper wire is inserted in inclined hole through through hole, inserting after inclined hole until copper wire makes axle rotate, make copper wire at the aperture place of inclined hole by stretch bending, the front end of copper wire is arranged in inclined hole, continue axle is rotated, axle drives copper wire to be looped around between the first circular groove and the second circular groove in rotation process, copper wire is cut off when copper wire is about to around full first circular groove and the second circular groove, the rear end of copper wire is made to be arranged in through hole, thus realize axially locating effect.
In sum, the utility model by arranging the first circular groove and inclined hole respectively on axle, at the inwall of axle sleeve, the second circular groove and through hole are set respectively, back-up ring is arranged between the first circular groove and the second circular groove, adopt compared with end face installs with prior art Elastic back-up ring, the utility model has saved required installing space greatly, and can play the effect of bi-directional axial location, and locating effect is better; When disassembly is desired, only need rotate backward axle, copper wire can be extracted out from inclined hole, dismantle comparatively convenient and swift.The utility model vibrational power flow advantages of simple.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of axial positioning mechanism as shown in Figures 1 to 4, comprise suitable axle 1, axle sleeve 2 and back-up ring 3, specifically, back-up ring 3 can be copper wire, steel wire or other materials with deformability are made, axle 1 is circumferentially provided with first circular groove 11 suitable with back-up ring 3, the bottom land of the first circular groove 11 is provided with inclined hole 12, the inwall of axle sleeve 2 is provided with second circular groove 21 corresponding with the first circular groove 11, as a kind of preferred implementation, first circular groove 11, the cross section of the second circular groove 21 is semicircle, furthermore, first circular groove 11, the diameter of the second circular groove 21 and back-up ring 3 is all equal, the bottom land of the second circular groove 21 is provided with the through hole 22 matched with inclined hole 12, through hole 22 runs through the outer wall of axle sleeve 2, back-up ring 3 is surrounded between the first circular groove 11 and the second circular groove 21, and one end of back-up ring 3 is arranged in inclined hole 12, the other end of back-up ring 3 is arranged in through hole 22, by copper wire back-up ring 3 being set around between the first circular groove 11 and the second circular groove 21, thus realize axially locating.
The utility model preferably adopts copper wire back-up ring 3, during assembling, first axle 1 is inserted in axle sleeve 2, until the first circular groove 11 and the second circular groove 21 position align, and make through hole 22 aim at inclined hole 12 position, then the front end of copper wire is inserted in inclined hole 12 by through hole 22, see Fig. 3, inserting after inclined hole 12 until copper wire makes axle 1 rotate, make copper wire at the aperture place of inclined hole 12 by stretch bending, the front end of copper wire is arranged in inclined hole 12, continue axle 1 is rotated, axle 1 drives copper wire to be looped around between the first circular groove 11 and the second circular groove 21 in rotation process, copper wire is cut off when copper wire is about to around full first circular groove 11 and the second circular groove 21, the rear end of copper wire is made to be arranged in through hole 22, thus realize axially locating effect.
