Abstract

The invention relates to an installation equipment for assembling an excavator big arm center box group. The installation equipment comprises a workbench, a movable positioning mechanism, a center positioning mechanism and a fixed positioning mechanism. The movable positioning mechanism is installed on the left side of the upper surface of the workbench. The center positioning mechanism is installed in the middle of the upper surface of the workbench. The fixed positioning mechanism is installed on the right side of the upper surface of the workbench. The installation equipment for assemblingthe excavator big arm center box group is reasonable in designing, scientific in structure, high in practicability, highly matched with workpieces in shape and good in fastening effect; and by using the installation equipment, a workpiece can be quickly and accurately clamped to be positioned, then the processing accuracy and the processing quality are improved, and the percent of pass of productsis increased finally.

Description

technical field [0001] The invention relates to the technical field of production and processing of excavators, in particular to an installation device used for group pairing of the central box body of the boom arm of the excavator. Background technique [0002] Excavator boom central box team group refers to the assembly and welding of the front and rear partitions, left and right side panels, and upper and lower cover plates of the excavator boom central box as required. Since the inner sides of multiple joints need to be welded, therefore Welding is difficult, and precise positioning of the workpiece is required to ensure the quality of the welding process. Such as image 3 As shown, the shape of the central box group of the boom arm of the excavator is relatively special. It has more curved surfaces and has mounting holes. The deflection phenomenon is prone to occur in the process, which makes it difficult to guarantee the processing quality. Contents of the invention...
