More general small-sized with holes with being connected of axle part because physical dimension is less, by the mounting type that be connected employing key connection of with holes of routine property with the axle part; Structures such as processing key and keyway on corresponding workpiece; Very inconvenience, and use bond structure, wherein the quality of processing of key and keyway and assembly quality are all had relatively high expectations; Key and keyway are to the degree of symmetry and the parallelism in axle center after accomplishing like the straightness accuracy of key and keyway, assembling, and required processing cost is higher; This procedure also can select to adopt welding that with holes is fixed on the part, but with holes accomplish with an axle part separate machined after, be assembled together then; Like this, consider that with holes is structure easy to wear, after using a period of time; Can according to circumstances give to change, this Placement be during with holes in the back wearing and tearing; Original only the needs changed with holes, and guarantees axle part well-formed, but pulls down relatively difficulty with holes from axle spare like this; Even pull down, also can to the outward appearance of axle spare with and mechanism cause wound.
The model utility content
The technical problem that the present invention will solve provides a kind of with holes linkage structure with the axle part, can effectively accomplish with holes when being connected on the part, and it is simple and be easy to the effect of with holes the replacing in later stage to reach processing and operating process.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is a kind of with holes linkage structure with the axle part, comprises a part that is provided with holes of center hole and cooperates with center hole, and said part outer peripheral surface is provided with at least one groove I; The hole wall of said center hole is provided with at least one and groove I corresponding groove II; With holes with axle after a part installs, and groove I and groove II are combined to form combined hole, are provided with the locking member with the combined hole interference fit in the combined hole.Linkage structure in the utility model has promptly been accomplished with holes through simple groove and locking member and has been connected with axle the effective of part, and easy to operate succinct, processing cost is lower, and has reached good connection effect; Can establish a plurality of combined hole, to reach more firm connection effect; For guaranteeing that with holes is limited with an axle part axial stroke, locking member is not moved in combined hole in addition, can adopt that punching press causes the locking member distortion to locking member, reaches the effect of locking member and combined hole interference fit.
As a kind of improvement, the axial length of said groove II is less than the height of center hole.Like this, the combined hole of groove I and groove II is a blind hole, can be to the locking member folk prescription to punching press or other working procedure processing, can accomplish cause the locking member distortion and with the effect of combined hole interference fit.
As a kind of improvement, the axial length of said groove II equals the height of center hole, and the axial length of said groove I is not less than the height of center hole.The axial length of groove II equals the height of center hole like this, and the axial length of groove I is not less than the height of center hole, and groove I and groove II combined hole are through hole, helps when needs are changed with holes, taking out easily locking member.
As a kind of improvement, said combined hole is a polygonal hole.Said locking member is that the combined hole of said groove I of cylinder and groove II is a polygonal hole, and groove I and groove II are the polygonal groove, is easy to processing.
As a kind of improvement, said combined hole is a circular hole.Said combined hole is a circular hole, and like this, locking member just can adopt multiple in processing structure, can reach equally with holes fixing with the axle part.
As a kind of improvement, said locking member is a cylinder.Locking member adopts column structure, is easy to process and take.
As a kind of improvement, said locking member is a cylinder.Cylinder is easier to adapt to multiple hole structure when cooperating.
As a kind of improvement, said locking member is prismatic.Prismatic quality of processing requires low, can save processing cost.
As a kind of improvement, said locking member is a spheroid.Spheroid adapts to the cooperation of multiple hole structure more easily, also is easy to processing.
As a kind of improvement, said locking member is that the combined hole of said groove I of ball and groove II is a circular hole, and said locking member is a ball, and ball is than other spheroids, and regular shape more can be easier to cooperate with the hole structure completion.
The utility model comes to be fixed on locking member through punching press locking member or other modes and can accomplish in the combined hole part and effective connection of with holes through establishing simple groove and a locking member simple in structure; Unit architecture is simple; Easy to process and can guarantee to connect respond well; In the time of need changeing with holes, strike down with holes and get final product, effectively realized the raising of working efficiency and the reduction of processing cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is with holes a kind of embodiment's a structural representation among Fig. 1;
Fig. 3 is with holes another kind of embodiment's a structural representation among Fig. 1;
Fig. 4 is a kind of embodiment's of Fig. 1 axis spare a structural representation.
Embodiment
Like Fig. 1, Fig. 2 and first kind of example structure shown in Figure 4, comprise with holes 1 and axle part 4, said with holes 1 middle part is provided with center hole 2; Said axle part 4 cooperates with said center hole 2, and a part outer peripheral surface is provided with at least one groove I 5, and center hole 2 hole walls are provided with at least one and groove I corresponding groove II3; When with holes correspondence is installed on the part; Groove I 5 and groove II3 are combined as a combined hole 6, are provided with a locking member 7 in the combined hole, and said locking member can limit a with holes edge axle part and circumferentially rotate; And with the mode that said locking member added exquisite distortion to be fixed on locking member in the combined hole; Limit endwisely slipping between with holes and the part simultaneously, the axial length of said groove II is less than the height of center hole, and groove I and groove II combined hole are blind hole; Can be to the locking member folk prescription to punching press or other working procedure processing, can accomplish cause the locking member distortion and with the effect of combined hole interference fit.
