Description
Technical field
The utility model relates to a kind of link technical field, and more particularly, it relates to a kind of pivot pin.
Background technique
At present, in machine part assembling, the heavy embedding mode such as pivot pin, straight pin, taper pin that has mostly adopted realizes the connection of positioning limit between each parts.When between link because of function need adopt pivot pin position spacing connection time, sometimes need to arrange positioning hole on pivot pin, by squeezing into locating stud in positioning hole, link is fixed, but pivot pin is in the process used, easily there is shearing force, but while there is shearing force, pivot pin can not be one straight cylindric, there will be block and size is uneven and situation, so easily there is monolateral fractureing, and pivot pin is after long-time use, contacting part between itself and the object be connected and fixed is easily stuck because getting rusty, not quick detachable, when not only damaging pivot pin at pivoting friction but also radial shear power can being produced to the locating stud in the positioning hole of pivot pin, easily cause the shear fracture of locating stud, the linkage function of pivot pin can be caused so unreliable, Security is poor.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide one pivot pin not easy to wear, comparatively reliable, easily detachable.
For achieving the above object, the utility model provides following technological scheme: a kind of pivot pin, comprise spindle nose, axle body and baffle plate, described spindle nose and baffle plate split the both sides at axle body, it is characterized in that: described spindle nose is provided with oil outlet, axle body is provided with the oil inlet hole be communicated with oil outlet, described oil inlet hole is vertical with oil outlet to be arranged, the diameter of described oil outlet is less than the diameter of oil inlet hole, the sidewall of the other end of described spindle nose and axle body connecting end is provided with platform, described platform place is provided with positioning hole, connecting rod is provided with between described spindle nose and bearing connecting end, described connecting rod comprises first portion and second portion, described first portion is connected with second portion one, described first portion outer wall becomes arc-shaped, described second portion outer wall becomes arc-shaped, described first portion outer wall circular arc opening direction is contrary with second portion outer wall circular arc opening direction.
By adopting technique scheme, spindle nose and axle body are respectively arranged with the oil inlet hole and oil outlet that are interconnected, this makes pivot pin in the process used, lubricant oil can be injected from oil inlet hole, increase the lubricity of contacting part between itself and institute's fixed object, and then just can easily pivot pin be disassembled from fixed object, the diameter of its oil outlet is less than the diameter of oil inlet hole simultaneously, the lubricant oil injected from oil inlet hole must be able to be flowed out from oil outlet is slow, improve the utilization rate to lubricant oil, by the appropriate location on pivot pin, platform is set, and positioning hole is arranged on platform, namely the cross section of this position is roughly D type, with link with the use of time, link arranges D nibs, like this, pivot pin will be stuck on link, in link high speed rotating or when there is shake, pivot pin would not rotate, pivot pin is not fragile, but also the positioning shaft be inserted in pivot pin positioning hole can be avoided to be subject to excessive radial shear power, and then the reliability of pivot pin can be improved, be connected with second portion one by first portion, described first portion outer wall becomes arc-shaped, described second portion outer wall becomes arc-shaped, undertaken stressed by circular arc, described first portion outer wall circular arc opening direction is contrary with second portion outer wall circular arc opening direction, utilize the two-way diverse location of the opening direction of circular arc stressed, strength is offset, thus pivot pin ability to bear is more strengthened.
