Abstract
The utility model discloses a kind of curved riveting cards of tack, it includes path section, transition region, major diameter section and oblique curved segment, and one end of path section and the one side of transition region connect, and the another side of transition region is connect with one end of major diameter section, and the other end of major diameter section transits to oblique curved segment.The problem of riveting access hardly possible can be efficiently solved using the curved riveting card in the bad region of narrow space or riveting access.The problem of avoiding because without suitable tack riveting impact card riveting quality, or even being riveted after workpiece need to being removed.Using assembly efficiency is improved after the curved riveting card of tack, reduce dismounting work.
Description
Technical field
The utility model relates to a kind of riveting card more particularly to a kind of curved riveting cards of tack.Suitable for Automatic manual transmission limited space,
Operating position is narrow, the assembly area that can not be riveted with conventional tack riveting card.
Background technique
Riveting is that two or more workpiece are deformed the assembly method that workpiece links together by rivet, existing
In aircraft, steamer and automobile and other industries are with extensive.Conventional tack riveting card is adapted to that wide open space is good, and operator and tool are not
The case where being limited by working region space.Before the curved riveting card of no tack, many flat head rivets can not use conventional tack riveting
Card riveting, and the curved riveting card of tack has filled up this vacancy.
Utility model content
To solve the problems, such as that flat head rivet riveting is limited by working region space, the utility model provides a kind of curved riveting of tack
Card.Convenience is provided to flat head rivet riveting work, improves assembly efficiency, reduces assembly parts dismounting.
The technical solution adopted in the utility model:
A kind of curved riveting card of tack, it includes path section, transition region, major diameter section and oblique curved segment, one end of the path section with
The one side of transition region connects, and the another side of the transition region is connect with one end of major diameter section, the other end transition of the major diameter section
To oblique curved segment.
Further, the oblique curved segment has an oblique bending angle, 0 ° of oblique bending angle≤30 ° <.
In the above-mentioned technical solutions, the diameter of the path section is less than the diameter of major diameter section.
Further, the path section is formed with flat conehead far from one end of transition region.The cone angle of the flat conehead=
45°。
Compared with prior art, the utility model has the beneficial effects that being adopted in the bad region of narrow space or riveting access
The problem of riveting access hardly possible can be efficiently solved with the curved riveting card.It avoids because riveting matter without suitable tack riveting impact card
The problem of measuring, or even being riveted after workpiece need to being removed.Using assembly efficiency is improved after the curved riveting card of tack, reduce dismounting work.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the partial schematic diagram at the utility model A.
1, path section, 2, transition region, 3, major diameter section, 4, oblique curved segment, 5, flat conehead.
Specific embodiment
In order to deepen the understanding to the utility model, with reference to the accompanying drawing and specific embodiment is described in detail, this
Embodiment described in specification is only used for explaining the utility model, is not used to limit the utility model.
The curved riveting card tool of tack and application method are illustrated below by Fig. 1, Fig. 2.One kind of the utility model is flat
Curved riveting card is improved for the rivet that pin head configuration is plane, is different from conventional tack riveting card, it include path section 1,
Transition region 2, major diameter section 3 and oblique curved segment 4, one end of path section 1 connect with the one side of transition region 2, the another side of transition region 2 with greatly
One end of diameter section 3 connects, and the other end of major diameter section 3 transits to oblique curved segment 3.
Oblique curved segment 3 has an oblique bending angle, 0 ° of oblique bending angle≤30 ° <.
The diameter of path section 1 is less than the diameter of major diameter section 3.
Path section 1 is formed with flat conehead 5 far from one end of transition region 2.Cone angle=45 ° of flat conehead 5.
Application method:
(1) path section of the curved riveting card of tack is packed into riveting gun head；
(2) other end (oblique curved segment) of the curved riveting card of tack is placed on flat head rivet, makes the curved riveting clamping of tack is close to resist
Rivet head；
(3) check whether the curved riveting card of tack and riveting gun gun body interfere with assembly parts；If interference, by rotating curved riveting card
Adjust the spatial position of curved riveting card and riveting gun gun body and assembly parts；
(4) another people resists rivet nail rod position with top iron, pulls riveting gun.
When the utility model rivets, due to " R " value on 360 ° of directions of plane only to curving, therefore can be in assembly
To adjust riveting gun, riveting card and the spatial position between riveting workpiece is needed by rotating the curved riveting card of tack according to the actual situation, is avoided
Interfere or easily cause the region collided with, to reach best riveting status, is convenient for worker operation.
Claims (5)
