Description
Technical field
The utility model relates to a kind of rocker arm as driving component application, refers in particular to the simple and rocker arm that intensity is high of a kind of structure.
Background technique
Connecting rod be two ends respectively with initiatively and driven member be connected and move and the rod member of power to transmit, wherein rocker arm is a kind of steering link.Along with expanding economy, in agricultural production, various agricultural machinery is more and more general, and rocker arm is the major part of sawing structure on agricultural machinery, and its claimed structure is simple, turn to and want flexibly, and have higher intensity.
Model utility content
The utility model object provides a kind of structure simple and the rocker arm that intensity is high to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rocker arm, mainly comprises the body of rod, main connected unit and secondary connected unit; Described main connected unit is provided with an oval connecting through hole; Described secondary connected unit is provided with small one and large one two attachment holes; Described main connected unit, the body of rod are identical with secondary connected unit thickness; The described plane of secondary connected unit and the plane orthogonal of the body of rod; Described main connected unit, the body of rod and secondary connected unit are structure as a whole; Angle between described secondary connected unit and the body of rod is shaped by twist and warping.
Preferably, the material of described rocker arm is 40CrMnMo.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The rocker arm of the utility model scheme, main application and agricultural machinery controls turning to of loading rocking arm, has structure simple, be easy to processing, turns to flexibly, intensity advantages of higher.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of rocker arm of the present utility model;
Accompanying drawing 2 is the structural representation at another visual angle of rocker arm of the present utility model;
Wherein: 1, the body of rod; 2, main connected unit; 3, secondary connected unit; 4, connecting through hole; 5, attachment hole.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Rocker arm of the present utility model, comprises the body of rod 1, main connected unit 2 and secondary connected unit 3; Described main connected unit 2 is provided with an oval connecting through hole 4; Described secondary connected unit 3 is provided with small one and large one two attachment holes 5; Described main connected unit 2, the body of rod 1 are identical with secondary connected unit 3 thickness; The plane of described secondary connected unit 3 and the plane orthogonal of the body of rod 1; Described main connected unit 2, the body of rod 1 and secondary connected unit 3 are structure as a whole; Angle between described secondary connected unit 3 and the body of rod 1 is shaped by twist and warping; Due to main connected unit 2, the body of rod 1 is identical with secondary connected unit 3 thickness and be structure as a whole, therefore feeding is simple, also processing is easy to, as long as select thickness just now suitable, by secondary connected unit 3 being twisted into plumbness, to realize the turning function of rocker arm with the body of rod 1 by twist and warping forming technique again after Blanking Shaping.
Further instruction, the material of described rocker arm is 40CrMnMo, and part needs modulation treatment and surfaces nitrided process, to ensure higher intensity and wear resistance.
The rocker arm of the utility model scheme, main application and agricultural machinery controls turning to of loading rocking arm, has structure simple, be easy to processing, turns to flexibly, the advantages such as intensity is high, long service life.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
