Abstract
The invention relates to a self-adaptation type connection rod, wherein internals of two pressing sleeves are manufactured into concave spherical surface structures, a diameter of the concave spherical surface inside the pressing sleeve is equal to a diameter of the outer spherical surface of a spherical pin shaft base, the two pressing sleeves are symmetrically arranged on both sides inside end portion connection rod holes of the connection rod body, the spherical pin shaft base is arranged inside the concave spherical surface in the middle of the two pressing sleeves, and the left pressing sleeve, the right pressing sleeve and the connection rod body are integratedly fixed through fastening bolts. According to the present invention, when the self-adaptation type connection rod works, one end rod portion of the connection rod body is connected with other movement parts, the movement parts form hinge connections inside the middle hole of the spherical pin shaft base through pin shafts, and the outer circle of the spherical pin shaft base and the concave spherical surfaces inside the two pressing sleeves can provide a certain position adjustment effect, such that the spherical pin shaft base is automatically adjusted to a corresponding position when a non-perpendicular state between the movement direction and the pin shaft exists so as to avoid serious defects of abnormal wear and easy damage on mechanical parts of mechanical parts due to the occasional non-perpendicular state between the connection rod movement direction and the pin shaft arranged on the connection rod body.
Description
Technical field
The present invention relates to a kind of connecting rod, particularly connecting rod during a kind of self adaption merit belongs to the component of machine technical field.
Background technique
In machinery; connecting rod generally is used for connecting two mutual moving elements; in the work of reality; because the moving direction of connecting rod can not be in vertical state sometimes with the bearing pin on being installed in connecting rod shank; usually the heel and toe wear of component of machine can occur, even the appearance of the serious problems of the component of machine that is damaged.
Summary of the invention
The object of the invention is to: a kind of self-adapting type connecting rod is provided, it is existing to overcome existing connecting rod: because the moving direction of connecting rod can not be in vertical state sometimes with bearing pin on being installed in connecting rod shank, the heel and toe wear of the component of machine that brings, damage the serious problems defective of component of machine easily.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of self-adapting type connecting rod, it is comprised of connecting rod shank, gland, ball pin axle bed, fixing bolt, it is characterized in that: gland forms by symmetrical two, two gland inside are made concave spherical surface and are got structure, the equal diameters of the outer spherical surface of the inner concave spherical surface of gland and ball pin axle bed, two glands are installed in the interior both sides of end tie rod holes of connecting rod shank symmetrically, the ball pin axle bed is installed in the concave spherical surface in the middle of two glands, clamping bolt with about two glands and connecting rod shank be fixed into one.
Beneficial effect: the present invention is when work, one end bar section of connecting rod shank is connected with other moving element, other moving element is hinged in the intermediate hole of ball pin axle bed by bearing pin, because the cylindrical of ball pin axle bed and two inner concave spherical surfaces of gland can have certain position regulation effect, so, when the direction of motion and bearing pin when having the out of plumb state, the ball pin axle bed is adjusted to corresponding position automatically, thereby avoid because because the moving direction of connecting rod can not be in vertical state, the heel and toe wear of the component of machine that brings sometimes with bearing pin on being installed in connecting rod shank, damage easily the serious problems defective of component of machine.
