Abstract

The invention relates to the field of excavators, and discloses a method for assembling a bucket of an excavator. The excavator includes an arm (2), a connecting rod (3), and a bucket (1), and the bucket (1) is provided with a first hinge The hole (7) and the second hinge hole (8), the arm (2) and the connecting rod (3) are respectively provided with the third hinge hole and the fourth hinge hole, the method includes: S1, using the transition hinge pin (4) Insert the first hinged hole (7) and the third hinged hole; S2, use the second hinged pin (6) to insert the second hinged hole (8) and the fourth hinged hole; S3, insert the first hinged pin (5) into the second hinged hole One hinge hole (7) and the third hinge hole. Through the above technical solution, the preliminary relative positioning of the bucket and the arm or the connecting rod can be realized through the transitional hinge pin, which solves the problem that the initial relative positioning is very difficult, and can more easily realize the relative positioning of the subsequent hinged holes and the hinged operation. The installation difficulty is reduced and the assembly efficiency is improved.

Description

technical field [0001] The invention relates to the field of excavators, in particular to an assembly method of a bucket of an excavator. Background technique [0002] The excavator includes a boom, which is connected with a stick, a connecting rod and a bucket. The bucket is hinged with the stick and the connecting rod through hinge pins, and can rotate relative to the stick and the connecting rod respectively, and the connecting rod is driven by an oil cylinder. Moving, the bucket can be rotated for digging operations. [0003] Although the hinge pins connecting the bucket of the excavator to the arm and the connecting rod are clearance fits, the fit tolerance range is small, and the hinge holes on the bucket are aligned with the hinge holes of the arm and the hinge holes of the connecting rod during assembly. Difficult, the assembly process of the hinge pin is time-consuming and laborious. Contents of the invention [0004] The object of the present invention is to pr...
