Description
Technical field
This utility model relates to a kind of fixing device, is specifically related to the end fixing device of a kind of bearing pin.
Background technology
In mechanical assembly, bearing pin right and wrong parts usually, especially use more frequent in the engineering mechanical devices such as high-altitude operation vehicle.In engineer applied, conventional is anti-rotation and axial positioning structure, in actual applications, the method preventing bearing pin from rotationally and axially moving is the most, as used interference to connect, adding back-up ring in one end of bearing pin and use anti-rotation crank throw etc., these methods to the making of bearing pin and have higher requirement to installing joint face, and interchangeability is undesirable, which adds production cost.
Utility model content
The technical problems to be solved in the utility model is: overcome technical problem of the prior art, it is provided that a kind of.
This utility model solves its technical problem and be the technical scheme is that
The end fixing device of a kind of bearing pin, including connection member, bearing pin；Being provided with pin shaft hole in described connection member, one end of described bearing pin is provided with pin-and-hole；Described bearing pin one end is installed in connection member by pin shaft hole, the pin-and-hole of the other end extend out to the outside of connection member, being provided with an anti-bull stick in the pin-and-hole of described bearing pin, described anti-bull stick one end is positioned at pin-and-hole, and the other end is fixed on the outer wall of connection member by a briquetting.
As further innovation of the present utility model, described briquetting includes a strip groove, the bottom opening of strip groove, and described anti-bull stick is fixed in briquetting by aforesaid strip groove.
As further innovation of the present utility model, described briquetting is fixed in connection member by screw.
As further innovation of the present utility model, the cross section of described strip groove is gradually-reducing shape, and the width of described strip groove opening part is more than the width bottom strip groove.
As further innovation of the present utility model, the afterbody at described anti-bull stick is provided with an annular relief, is provided with an annular groove corresponding with aforementioned lobe in one end of described pin-and-hole, and annular groove is coaxial with pin-and-hole and connects.
The beneficial effects of the utility model are:
By technique scheme, major advantage of the present utility model is, is preventing bearing pin from rotationally and axially moving, and while not affecting bearing pin bonding strength, anti-bull stick can use the work tender such as screw, pin, reduces production cost；Briquetting processing is simple, and the requirement to connection member installed surface reduces, and does not affect the requirement of strength of bearing pin simultaneously, and tapered strip groove can effectively clamp anti-bull stick, it is ensured that intensity.
