Abstract
The utility model relates to a fastening device, and particularly relates to a fastening device which is used for a punching riveting mechanism and is simple and portable in structure. The fastening device comprises a pressure head and a base, a rivet sleeve is arranged between the pressure head and the base, a rivet sleeve hole is arranged on the rivet sleeve, the diameter of the rivet sleeve hole is larger than that of a rivet to be used, the rivet sleeve is provided with a locating head, the base is provided with three locating pins, and the three locating pins which are in an obtuse triangle shape are distributed on the upper surface of the base. The fastening device utilizes a design that a general floating platen is replaced by the rivet sleeve, so that the usage of the fastening device is portable and flexible, the application range is wide, the cost is low, the structure is simple, and the design is reasonable.
Description
Technical field
The utility model relates to a kind of clamping device, especially relates to a kind of simple and light clamping device of using towards the riveter structure.
Background technology
As everyone knows, the connection of many plate parts need be through accomplishing towards the riveter structure, the general bulky heaviness of riveter structure of dashing, and the pressed sheet of bulk uses very inconvenient, and cost is also higher.Like Chinese patent: the riveting mechanism of cylindrical pins (CN 201988670 U), this device uses upper punch and low punch to cooperate clamp jig, uses hydraulic press riveted joint part, and structure is complicated, and its pressing plate volume is big, heavy inconvenience, cost height.
Summary of the invention
The utility model mainly is to the above-mentioned technical problem of existing in prior technology, provides a kind of simple and light, rivets the firm riveter structure clamping device that dashes.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of towards riveter structure clamping device; Comprise pressure head and base; It is characterized in that being provided with between described pressure head and the base rivet cover; Described rivet puts and has the rivet trepanning, and described base is provided with some alignment pins.The part that to rivet during use is fixed near alignment pin; Rivet is put into the riveted holes of part; The rivet cover is enclosed within on the rivet, and starting can be with the part riveted joint firmly towards the riveter structure, and the use that the design that substitutes general floating platen with the rivet cover can make this clamping device is light and flexible more; The scope of application is wider, and is simple in structure, reasonable in design.
As preferably, described rivet cover is provided with positioning head, and described rivet cover bore dia is greater than rivet diameter.The easy design of positioning head is sleeved on the rivet cover on the rivet, and rivet cover bore dia is easy to form fastening ailhead greater than rivet diameter.
As preferably, described alignment pin is three, and described three alignment pins triangle in obtuse angle are distributed in the upper surface of base.Three alignment pins distributing of triangle can satisfy the fixedly securing of part of more shape in obtuse angle, and are simple and reasonable.
Therefore, the utlity model has characteristics such as simple and light, that riveted joint is firm.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Accompanying drawing 2 is another kind of structural representations of the utility model.
Among the figure: pressure head 1; Rivet cover 2; Alignment pin 3; Base 4; Part riveted joint mouth 5; Part 6; Rivet trepanning 7; Positioning head 8.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment 1:
Like Figure of description 1, shown in 2, a kind of towards riveter structure clamping device, comprise pressure head 1 and base 4; It is characterized in that being provided with between described pressure head 1 and the base 4 rivet cover 2; Have rivet trepanning 7 on the described rivet cover 2, the rivet diameter that the diameter of this rivet trepanning 7 uses greater than need also is provided with positioning head 8 on the described rivet cover 2; Described base 4 is provided with three alignment pins 3, and described three alignment pins 3 triangle in obtuse angle are distributed in the upper surface of base 4.The part that to rivet during use fixes near three alignment pins 3, and rivet is put into the riveted holes 5 of part 6, and rivet cover 2 is enclosed within on the rivet, starts towards the riveter structure, and pressure head 1 is exerted pressure downwards and can rivet be squeezed into part 6 and with each part riveted joint firmly.The use that the design that substitutes general floating platen with rivet cover can make this clamping device is light and flexible more, and the scope of application is wider, and is with low cost, simple in structure, reasonable in design.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
