Abstract
The invention discloses a loading machine rocker arm with a lubrication structure and a loading machine. The loading machine rocker arm comprises two rocker arm plates symmetrically arranged, connection holes are formed in the two ends of each rocker arm plate, pin shaft bases are arranged at the installing positions of pin shafts of the two rocker arm plates, the two rocker arm plates are connected into a whole through the pin shaft bases, and lubrication holes lubricating the pin shafts are formed in the pin shaft bases and communicate with the external through oil circulation pipes. According to the loading machine rocker arm and the loading machine, the box type rocker arm structure mode with low cost is adopted, the problems that the machining technology of pin shaft oil ways is difficult and the pin shafts are low in reliability are solved by changing the design of lubrication points, and the requirements for the low cost, the simple technology and the high reliability can be met simultaneously.
Description
Technical field
The invention discloses a kind of loader rocking arm with lubrication system and loader.
Background technology
Loader rocking arm has one-board and box two kinds of structures at present, and case structure is by from heavy and light and reliability height ratio
Veneer rocking arm has some superiority.But the hinged oil site of box rocking arm is all disposed within hinging pin shaft end face substantially, because of rocker-arm roller pin
Axle is longer, is machined to the oilhole in the middle of bearing pin from end face very deep, and processing technique is extremely difficult, and this point is also box shaking
Arm inferior position is in the place of veneer rocking arm.So, research and develop a kind of box rocking arm and on its hinging pin shaft end face, do not open lubrication
Hole, the problem that solution prior art cost, manufacturability can not get both, there is certain economic benefit.
Existing market loader rocking arm has veneer and box two kinds of versions, and the lubricating system of rocking arm has two kinds of structure shapes
Formula aminoacyl site lubrication and B position lubricate.Wherein one-board rocking arm has aminoacyl site and two kinds of B position lubricating system, and box rocking arm is only
There is B position one lubricating system (shown in accompanying drawing 1,2)；There is following defect in this lubricating system waved:
1) one-board rocking arm: although aminoacyl site lubrication can solve B position and lubricate caused bearing pin oil duct processing technique difficulty
Problem, but its design of one-board rocker structure is bigger than box rocking arm weight, cost is the highest；
2) box rocking arm: although than one-board rocking arm from heavy and light, low cost, but lubrication must be from B position (swivel pin
Axial end), there is oil duct processing technique difficulty and the problem of band oil duct bearing pin reliability reduction.
Summary of the invention
The present invention is primarily directed to the shortcoming of prior art, discloses a kind of loader rocking arm with lubrication system, adopts
By lower-cost box rocker structure form simultaneously, the problem that oil site design solves bearing pin oil duct processing technique difficulty is changed
And bearing pin integrity problem, can meet that low cost, technique is simple and the high three aspect requirements of reliability simultaneously.
The technical solution used in the present invention is as follows:
A kind of loader rocking arm with lubrication system, including two symmetrically arranged rocker plate, the two ends of rocker plate are equal
Being provided with connecting hole, the position installing bearing pin two rocker plate is provided with axis pin base, and two rocker plate are connected by described axis pin base
Being integrated, be provided with the lubrication hole to bearing pin lubrication on described axis pin base, described lubrication hole is connected with extraneous by oil pipe
Logical.
Further, being also equipped with reinforcing plate between two described rocker plate, reinforcing plate is welded on two rocker plate
On.
Further, described reinforcing plate is enclosed around described axis pin base one, forms an enclosed construction.
Further, described reinforcing plate is provided with oil through, and one end that oil pipe is in communication with the outside is arranged on described
In oil through.
Further, described reinforcing plate is additionally provided with the element that the mouth of pipe to oil pipe is protected.
Further, the described spherical plate that protection element is an indent, it is welded in reinforcing plate.
Further, the two ends of described axis pin base are welded in two rocker plate.
A kind of loader, its rocking arm uses foregoing rocking arm, when being lubricated rocking arm bearing pin, passes through oil pipe
Realize.
The beneficial effect that technical solution of the present invention is brought:
The present invention uses lower-cost box rocker structure form simultaneously, by arranging oil site on axis pin base, changes
Having become existing oil site position, this invention solves the difficult problem of bearing pin oil duct processing technique and bearing pin reliability is asked
Topic, can meet that low cost, technique is simple and the high three aspect requirements of reliability simultaneously.Brighter than its beneficial effect with existing structure
Aobvious, as a example by certain the 50 loader rocking arm produced in batches at present:
Accompanying drawing explanation

Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings:
As described by background section, the most all there are some defects in current one-board rocking arm and box rocking arm
(as shown in Figure 1, 2), the invention discloses a kind of loader rocking arm with lubrication system, use lower-cost box rocking arm
Version simultaneously, changes oil site design and solves problem and the bearing pin integrity problem of bearing pin oil duct processing technique difficulty,
Can meet that low cost, technique is simple and the high three aspect requirements of reliability simultaneously；Concrete structure is as follows:
Embodiment 1
As shown in Fig. 3-1,3-2, the rocker structure of the present invention is mainly by two rocker plate being symmetrically installed 1, shake at two
The position installing bearing pin in arm plate 1 is provided with axis pin base 5, and two rocker plate 1 are connected as one by described axis pin base 5, constitutes case
The main body of formula rocking arm；
Being designed with lubrication hole at axis pin base 5, lubrication hole is in communication with the outside by oil pipe 4, lubrication hole and oil pipe 4 interior
Hole communicates, for logical oil, it is achieved the lubrication to bearing pin；
Reinforcing plate 6 is designed with oil through, is exposed to outside rocking arm, as oil site for oil pipe 4 outer face；Logical
Oilhole is arranged on from the nearest position of the lubrication hole of axis pin base 5, so that the length of oil pipe 4 is the shortest, reaches optimal profit
