Description
Technical field
The utility model relates to port mechanical equipments to install parts technical field, especially belong to a kind of suitable for loading
The oilhole anti-clogging pivot pin of mechanical shovel bucket rocker arm.
Background technique
VOLVO loading machine is mainly responsible for stacks of cargo high, train loading and automotive and the operations such as clears out a harbour, and utilization rate is high, workload
Greatly, the daily load activity duration on 16 hours, prolonged high load capacity operation make the technology status of loading machine by
To great challenge, great difficulty is brought to the guarantee of equipment, is found in practical maintenance, the pivot pin Oil Guide on loading shovel rocker arm
The design in hole bears the maximum middle position of strength in pivot pin, and pivot pin service life is lower than 2 months, and frequent rocker arm pivot pin is disconnected
The bus dispatching rate that failure seriously affects equipment is split, brings certain influence to harbour production.
Summary of the invention
The purpose of this utility model is to provide a kind of loading shovel rocker arm oilhole anti-clogging pivot pin, be mentioned with reaching
High pivot pin service life and the purpose for guaranteeing production efficiency.
Loading shovel rocker arm provided by the utility model oilhole anti-clogging pivot pin, including pivot pin ontology, pivot pin sheet
The both ends of body are respectively equipped with fixation hole, and pivot pin ontology one end has oil guiding hole, which is characterized in that the oil guiding hole is along axis
Heart line is extended inwardly to outward at pivot pin 1/3, and extends upwardly to pivot pin body outer surface perpendicular to shaft centre line, wherein
Oil guide groove is offered on pivot pin body outer surface, the oil guide groove includes the oil guiding hole on pivot pin body outer surface, and Oil Guide
Slot is at the midline position that one end extends to pivot pin ontology.
Further, the shape of above-mentioned oil guide groove is ellipse or circle or strip.
Further, oil guide groove one end is tangential on the oil guiding hole on pivot pin body outer surface.
Loading shovel rocker arm provided by the utility model oilhole anti-clogging pivot pin, by by loading shovel rocker arm
The oil guiding hole of pivot pin designs at pivot pin 1/3, to further improve the intensity and hardness of pivot pin；It is provided on pivot pin ontology
Oil guide groove, to increase lubricant effect and Oil Guide hole plug can be effectively prevent, in conclusion the utility model is with practical
Property good effect strong and that guarantee production operation efficiency.
Detailed description of the invention
Attached drawing part discloses the utility model specific embodiment, wherein
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is the right side view of the utility model；
Fig. 3 is 1 top view of the utility model embodiment；
Fig. 4 is 2 top view of the utility model embodiment.
Specific embodiment
As shown in Figs 1-4, loading shovel rocker arm provided by the utility model oilhole anti-clogging pivot pin, including pivot pin
Ontology 1, the both ends of pivot pin ontology are respectively equipped with fixation hole 2, and pivot pin ontology is put into swing arm sleeve, and two with pivot pin ontology
End, by fixation hole fitted bolt, is coupled fixation with the mounting flange of loading shovel.In addition, the pivot pin ontology
One end has an oil guiding hole 3, oil guiding hole by pivot pin outer end along shaft centre line extend inwardly to inside pivot pin 1/3, and it is vertical
Pivot pin body outer surface is extended upwardly in shaft centre line, wherein oil guide groove 4 is offered on pivot pin body outer surface, it is described
Oil guide groove include oil guiding hole on pivot pin body outer surface, and oil guide groove extends to the midline position of pivot pin ontology in one end
Place.Above-mentioned oil guide groove can be ellipse, circle, strip or other shapes.
In embodiment 1 as shown in Figure 3, the oval oil guide groove of width 12mm long 70mm and depth 2-3mm, Oil Guide are selected
It include the oil guiding hole that pivot pin body outer surface is extended upwardly to by pivot pin body interior inside slot.Certainly, can also be as shown in Figure 4
In embodiment 2, oil guide groove is tangential on the oil guiding hole in this dignity of pivot pin in one end.In this way, in the intensity, the hardness that improve pivot pin
While, moreover it is possible to play the technical effect for preventing Oil Guide hole plug.
