Detailed description of the invention
Fig. 1 is the structural representation of the pin in the present invention in one embodiment of pin component used in vibration environment
Figure；
Fig. 2 is that the structure of the anticreep sleeve in the present invention in one embodiment of pin component used in vibration environment is shown
It is intended to；
Fig. 3 is the usage state diagram of pin component in the present invention.
Specific embodiment
The implementation of pin component used in vibration environment is for example shown in Fig. 1 ~ 3: matching including pin 1 and with pin
Anticreep sleeve 7, pin 1 includes the pin body that extends along the longitudinal direction of axis, and pin body is the multi-diameter shaft of three-stage structure
Structure, three sections of multi-diameter shafts are respectively first segment 2, second segment 4 and third section 5 from back to front, wherein first segment 2, second segment 4 and the
Three section 5 of diameter is sequentially reduced, and second segment 4 is formed for the inserting section with respective pins nail hole interference inserting, first segment and second
It is formed between section for the anticreep step 3 with the cooperation of the rear hole opening's edge block of pin hole.The front end of third section is provided with end face
Rivet hole 6 is turned over, while third section also constitutes the suit section for the guiding suit of anticreep sleeve 7, the platform between second segment and third section
Terrace is used to that anticreep sleeve block location fit, the front end of the inner hole of anticreep sleeve to be provided with that turn over rivet hole with end face corresponding
Turn over riveting speaker hole 8.
Third section 5 and end face turn over rivet hole 6 together form for anticreep sleeve turns over that riveting connect first turns over riveting knot structure.Under
Face is illustrated the use of this pin component by taking the use of this pin component in spring lock 9 as an example, as shown in figure 3,
By in the pin hole 10 for being inserted into spring lock of pin 1 from back to front, 5 diameter of third section of pin is smaller and plays and draws
Lead guiding role so that pin is easier to insert into pin hole, then by anticreep sleeve from front to back be set in third section 5
On, until the step surface block cooperation between the rear end and second segment, third section of third section 5, the outer diameter of anticreep sleeve is greater than the
Two sections of outer diameter turn over riveting and operates using turning over riveting tool and turning over rivet hole to end face, specifically refer to turn over riveting tool with taper or
Spherical turns over riveter, turns over riveter by this and turns over rivet hole 6 to end face and carries out axial pressure, make end face turn over it is swollen outside the hole wall of rivet hole 6 and
It is pressed on the hole wall for turning over riveting speaker hole, the edge that rivet hole is turned in the end face after turning over riveting is flushed with the outer diameter of anticreep sleeve, and end face is turned over
The deformation of rivet hole belongs to expendable plastic deformation, thus guarantee the firm limit to anticreep sleeve, even if in vibration environment,
Will not occur loosening phenomenon, to ensure that this pin component can be to use in vibration environment.
Pin feature form of the invention is simple, and riveting operation is convenient easy, the interference fit of second segment and pin hole, then
In addition the riveted structure of anticreep sleeve greatly improves the fixed reliability of pin using the double-deck fixed form from structure, from
And meet the requirement of complex vibration environment；The diameter that the diameter of third section is less than pin hole can be improved to play guide function
The elastic conjunction efficiency of the installation of pin and second segment and pin hole；Made by the depth that control third section and end face turn over rivet hole
Pin turns over that the edge of materials after riveting is concordant with the outer diameter of anticreep sleeve, and the riveting speaker hole 8 that turns over of anticreep sleeve ends inner hole makes in addition
The diameter that pin turns over riveting position gradually increases, and improves the reliability for turning over riveting.
In other embodiments of the invention, pin body may not be step axle construction, at this time the diameter of third section
Can also be consistent with the diameter of second segment, the diameter of first segment can also be consistent with the diameter of second segment, at this time can be first
End face is set in section and turns over rivet hole, rivets an anticreep sleeve on second segment to prevent the anticreep at this end of pin, first segment and the
End face on one section, which turns over rivet hole and constitutes second, turns over riveting knot structure；Second segment and pin hole can also be with clearance fits；First turns over riveting knot
Riveting between structure and anticreep sleeve is also not limited to turn up the technique of riveting, such as anticreep sleeve has one is deep into
The connection end with bottleneck in rivet hole is turned in end face, at this time end face turn over rivet hole can be at the undergauge with varus and with connection end
Match to realize the limit to anticreep sleeve；The upper of anticreep sleeve is turned over riveting speaker hole and can not also be set, at this point, riveting is turned in end face
Hole can directly be turned in riveting to the end face of anticreep sleeve.
The implementation of pin is for example shown in Fig. 1 ~ 3: described in the specific structure of pin and above-mentioned each pin assembly embodiment
Pin is identical, and this will not be detailed here.
