Description
Technical field
The utility model relates to loader and extends the structural member of type, especially relates to a kind of loader box type rocking arm.
Background technology
At present, loader with and the rocking arm side plate of spin-off between generally only have three horizontal stiffeners, the commissure stress of stiffener is concentrated, and easily forms fatigue fracture, and whole torsional deformation easily occurs overload.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, and a kind of loader box type rocking arm is provided, and with four blocks of boxboards, forms box reinforcement structure, can meet the demand of Strength and stability.
The technical solution adopted in the utility model is: a kind of loader box type rocking arm, comprises rocking arm right plate, rocking arm left plate, packing ring, lower boxboard, front boxboard, sleeve pipe, upper boxboard and rearing-box plate;
Described rocking arm right plate, rocking arm left plate, upper boxboard, lower boxboard, front boxboard and rearing-box plate soldering group are synthesized a case structure;
The top of described rocking arm right plate and rocking arm left plate is provided with upper shaft hole, upper shaft hole is positioned at the top of boxboard; the bottom of rocking arm right plate and rocking arm left plate is provided with lower shaft hole; lower shaft hole is positioned at the below of lower boxboard, and the middle part of rocking arm right plate and rocking arm left plate is provided with intermediate shaft hole;
The upper inner of described rocking arm right plate and rocking arm left plate is all welded and is provided with packing ring, the axis hole of packing ring and upper shaft hole centering laminating; The lower inside of rocking arm right plate and rocking arm left plate is all welded and is provided with packing ring, the axis hole of packing ring and lower shaft hole centering laminating; Described sleeve pipe passes described intermediate shaft hole, and welds with rocking arm right plate, rocking arm left plate.
As preferably, the upper shaft hole of described rocking arm right plate and lower shaft hole side are provided with the screwed hole of available corresponding bolt fixed pin shaft fixed head.
As preferably, the interior boring ratio upper shaft hole of described sleeve pipe, the internal diameter of lower shaft hole be large 5mm all.
Beneficial effect: the utility model is rational in infrastructure, stress distribution is even, and Strength and stability is high, can effectively prevent the side plate torsional deformation because of overload generation, reliability and the application life of greatly having improved rocking arm.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of loader box type rocking arm of the utility model;
Fig. 2 is the sectional view of A-A face in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, 2: a kind of loader box type rocking arm, mainly comprises rocking arm right plate 1, rocking arm left plate 2, packing ring 3, lower boxboard 4, front boxboard 5, sleeve pipe 6, upper boxboard 7, rearing-box plate 9.The axis hole of two packing rings 3 respectively with two axis hole centerings up and down the laminating of rocking arm right plate 1, with around fillet weld seam be rocking arm right plate 1 soldering member; The axis hole of two other packing ring 3 respectively with two axis hole centerings up and down the laminating of rocking arm left plate 2, with around fillet weld seam be rocking arm left plate 2 soldering members; Sleeve pipe 6 packs rocking arm right plate 1 soldering member and rocking arm left plate 2 soldering members intermediate shaft hole separately into, and symmetrical rocking arm right plate 1 soldering member and rocking arm left plate 2 soldering members adjusted are to given size, then use fillet weld seam around; Lower boxboard 4, front boxboard 5, upper boxboard 7, rearing-box plate 9 in accordance with regulations position and size carry out spot welding connection, then by fillet weld around, entirely weld, and form box reinforcement structure.
Near two axis holes up and down of the utility model rocking arm right plate 1, there are screwed hole 8 and screwed hole 10, available corresponding bolt fixed pin shaft fixed head; The large 5mm of internal diameter of the interior boring ratio rocking arm right plate 1 of sleeve pipe 6, two axis holes up and down of rocking arm left plate 2.
It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each ingredient all available prior art realized.
