Description
Technical field
The utility model belongs to mechanical part linkage structure field, particularly relates to a kind of interface arrangment for mechanical part docking.
Background technique
At present, cannot be fastenedly connected by threaded connector mode during a lot of mechanical part end face docking, be fastenedly connected also more difficult well.Adopt oblique screw to be connected with bolt at the edge of two mechanical parts and also there is certain narrow limitation, especially to some component of machine, the fore side twisting screw thread is limited especially, and oblique screw processing cost is high, edge strength is low, is easily that mechanical part is scrapped because processing such screw.And run through according to long screw, not only processing cost is large, and high to required precision, is also easy in addition destroy mechanical part bulk strength.
Summary of the invention
Goal of the invention of the present utility model in order to provide a kind of rigidity interface arrangment for mechanical part docking, this rigidity interface arrangment not only novel structure, and can make rapid abutting joint between mechanical part end face, and is formed to closely cooperate and complete and is fixedly connected with.
In order to realize foregoing invention object, the utility model have employed following technological scheme:
A kind of rigidity interface arrangment for mechanical part docking, described mechanical part comprises the first mechanical part for mutually docking and the second mechanical part, described rigidity interface arrangment comprises and is fixed on cylindrical attachment post in the first mechanical part and is located at the second mechanical part relevant position and the blind hole matched with cylindrical attachment post, described cylindrical attachment post outer end is provided with stainless steel dop, what described stainless steel dop top was provided with that multiple axis cuts open splits groove, multiplely split groove regular distribution, and described stainless steel dop top portion is slit into multiple arc card division, arc card division outer side wall is equipped with annular projection, the external diameter that annular projection surrounds equals the internal diameter of described blind hole, arrange multiple steel ball receiving cavity along blind pore wall circumference inside described blind hole, steel ball receiving cavity mates with described ball size, and described steel ball is riveted in steel ball receiving cavity, described steel ball radially the highest outstanding distance be not more than described in split well width, after cylindrical attachment post stretches into blind hole, described steel ball position to be stuck in inside described annular projection and drive fit.
As preferably, the diameter of described cylindrical attachment post inner end is equal with described blind hole internal diameter, and the diameter of the stainless steel collet body of outer end is less than described blind hole internal diameter, and the inner side surface of described annular projection is the arcuately inclined-plane that arranges of card division outer wall circumference.
Have employed the rigidity interface arrangment for mechanical part docking of technique scheme, this rigidity interface arrangment is the cooperation of blind hole and attachment post, is provided with stainless steel dop in cylindrical attachment post outer end, and what stainless steel dop offers multiple axis cuts open splits groove.And be provided with in blind hole can rigidity roll steel ball, when cylindrical attachment post is axially pressed into blind hole cooperation, the deformation elastic force that groove pressing flicks is split by stainless steel part, the mechanical part making two to dock is retainer shaft and radial drive fit simultaneously, fiting effect is good, need not screw thread be twisted, coordinate efficient and convenient, be fastenedly connected rear stability good.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
One is as Figure 1-5 used for mechanical part, and mechanical part wherein comprises the first mechanical part 1 and the second mechanical part 2 for mutually docking.
As shown in Figure 1, Figure 2 and Figure 3, this rigidity interface arrangment comprises and is fixed on cylindrical attachment post 3 in the first mechanical part 1 and is located at the second mechanical part 2 relevant position and the blind hole 20 matched with cylindrical attachment post 3.Cylindrical attachment post 3 outer end is provided with stainless steel dop 4, as shown in Figure 5, what stainless steel dop 4 top was provided with that three axis cut open splits groove 41, three split groove 41 regular distribution, and above-mentioned stainless steel dop 4 top portion is slit on arc card division 40 outer side wall of 40, three, three arc card divisions and is equipped with annular projection 401.The diameter of above-mentioned cylindrical attachment post 3 inner end is equal with blind hole 20 internal diameter, the diameter of stainless steel dop 4 body of outer end is less than blind hole 20 internal diameter, the inner side surface of annular projection 401 is inclined-planes of arcuately card division outer wall circumference setting, and the outer side surface of annular projection 401 is cambered surfaces.
Above-mentioned three annular projections 401 external diameters surrounded equal blind hole 20 internal diameter, and inside blind hole 20, multiple steel ball receiving cavity 200 is set along blind pore wall circumference, steel ball 201 is set in steel ball receiving cavity 200, and steel ball receiving cavity 200 mates with above-mentioned steel ball 201 size, steel ball 201 is riveted in steel ball receiving cavity 200 and can rigidity rolls, can not be pressed into by elasticity, steel ball 201 radially the highest outstanding distance is not more than the width splitting groove 41.After cylindrical attachment post 3 stretches into blind hole 20, steel ball 201 rolls and is pressed in, the outer side surface of annular projection 401, arc card division 40 pressing is impelled to draw close, split groove 41 elastic closure, when steel ball 201 rolls across annular projection 401 the highest protrusion position, the final position of steel ball 201 is stuck in inside annular projection 401, the inner side surface of annular projection 401 is inclined-planes, so, the while of making the first mechanical part 1 and the second mechanical part 2 under the stainless steel deformation elastic force effect of arc card division 40, retainer shaft coordinates to drive fit and radial compaction.
