Description

Vehicle rotary unequal-side rivet with guide function

Technical Field

The utility model relates to a rivet technical field, concretely relates to automobile-used area direction gyration inequilateral rivet.

Background

The rivet is widely used in various industries as a component connecting device, generally, people have the connecting function of the heavy rivet, the development and utilization of the firm function of the rivet are insufficient, the riveting direction of the component is insufficient, and particularly in the field of small cars, people need the vehicle rivet with the guide rotary unequal sides to increase the riveting firmness of the rivet and the bearing. The rivet can rivet a plurality of parts and the middle part contains the solid of revolution part, and both ends part is irregular and have the relative position requirement, and this application has adopted a neotype one end can weld, and the other end can rivet the special rivet of mode.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an automobile-used not equilateral rivet of area direction gyration to the aforesaid of prior art is not enough and the defect, in order to solve above-mentioned problem.

The utility model provides a technical problem can adopt following technical scheme to realize:

the utility model provides an automobile-used area direction gyration inequilateral rivet, includes the rivet, its characterized in that, the rivet has set gradually head end, flange, first bearing fender, second bearing fender and inequilateral polygon by the front end to the tail end, flange, first bearing fender, second bearing fender and inequilateral polygon's external diameter decrease progressively in proper order, still be provided with the transition bearing who is the conical surface structure between first bearing fender, the second bearing fender and keep off, the terminal surface that adversary's piece was kept away from to the flange sets up to subtract heavy inclined plane structure, the head end middle part is provided with the lightening hole, be provided with the identification point that corresponds with a certain identification limit of inequilateral polygon on the head end.

In a preferred embodiment of the present invention, the non-equilateral polygon has a hexagonal structure, and one side of the polygon is an arc side.

Since the technical scheme as above has been adopted, the utility model discloses a rivet structure is ingenious, keeps off the technical scheme through the transition bearing that adopts to be conical surface structure, gets into the dead bearing hole more smoothly when can making rivet and bearing assembly, and this transition bearing keeps off and has the direction function, and prevents that the rivet from blocking dead phenomenon when the bearing assembly, can also do benefit to the zonulae occludens between the adversary piece, reduces its clearance in the function, avoids the too big noise and the too pine phenomenon that produce in clearance. Moreover, the utility model discloses an inequilateral location design of rivet has the mistake proofing effect.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.

Referring to fig. 1 to 5, the tape guide turning inequilateral rivet for vehicle includes a rivet 100, and is characterized in that the rivet 100 is provided with a head end 110, a flange 120, a first bearing stop 130, a second bearing stop 140 and an inequilateral polygon 150 in sequence from a front end to a rear end, the inequilateral polygon 150 in this embodiment is a hexagonal structure 151, and one side is an arc-shaped side 152. The outer diameters of the flange 120, the first bearing retainer 130, the second bearing retainer 140 and the inequilateral polygon 150 are gradually decreased, a transition bearing retainer 160 with a conical surface structure is further arranged between the first bearing retainer 130 and the second bearing retainer 140, the end face, far away from the opponent, of the flange 120 is provided with a weight-reducing inclined plane structure 121, the middle of the head end 110 is provided with a weight-reducing hole 111, and the head end 110 is provided with an identification point 112 corresponding to an arc-shaped side 152 of the inequilateral polygon 150.

The working principle of the utility model is as follows:

place stamping workpiece skeleton 1 on the production line earlier, then the utility model discloses a frock location is put into to inequilateral polygon 150, stamping workpiece skeleton 1 embolias on first bearing keeps off 130, interior terminal surface 122 with flange 120 welds with stamping workpiece skeleton 1, then embolia second bearing fender 140 to rotating member 2 on, transition bearing keeps off 160 and has the guide function, and prevent the dead phenomenon of rivet card when the bearing assembly, can also do benefit to the zonulae occludens between the adversary spare, reduce its clearance in the function, avoid the too big noise and the too loose phenomenon of production in clearance. Finally, the shifting fork 3 is sleeved on the unequal polygon 150, riveting is carried out on the tool according to the unequal polygon 150, the relative position of the shifting fork 3 and the stamping part framework 1 is guaranteed to be fixed through the assembling technological process, the length sizes of the first bearing block 130 and the second bearing block 140 are larger than the thicknesses of the stamping part framework 1 and the rotary part 2, and the stamping part framework 1 and the rotary part 2 cannot be riveted and fixed after riveting.

The utility model has the advantages as follows:

1. the rivet has the function of an inequilateral polygon, namely, fixing the positioning of the stamping part framework 1, fixing the positioning of the shifting fork 3, and finally achieving the relative position requirement of the stamping part framework 1 and the shifting fork 3.

2. The corresponding inequilateral polygon 150 on the shifting fork 3 is consistent with the shape of the rivet 100, so that the position of the rivet 100 is not changed, the error-proofing function is realized, and the direction judgment of the inequilateral polygon 150 can be well confirmed on the identification point 112.

3. The transition bearing retainer 160 is convenient to install, facilitates the tight connection between the stamping part framework 1 and the rotating part 2, reduces the gap between the stamping part framework and the rotating part in operation, and avoids the noise and the over-loosening phenomenon caused by the overlarge gap.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
