Box assembling production line, box assembling method, production system and production method for arm joint

Abstract

The invention discloses a box assembling production line for an arm joint. The arm joint comprises an upper cover plate, a lower cover plate, a web and a partition plate. The box assembling production line comprises an annular track and an automatic guiding trolley arranged on the annular track movably. A web locating station, an inner welding station and an upper cover plate locating station are arranged on the annular track sequentially. The web locating station is used for locating the lower cover plate to be assembled and the web to be assembled, the inner welding station is used for welding the located lower cover plate and web together from the inside and welding the partition plate and the web from the inside, the upper cover plate locating station is used for assembling the upper cover plate to be assembled above the welded web and the partition plate and locating the upper cover plate to form a box structure. The invention further discloses a box assembling method, a production system and a production method for the arm joint. The box assembling production line enables box assembling operation of the arm joint to be automatic assembling line operation, is high in working efficiency and reduces labor.

Description

technical field [0001] The invention relates to the production of boom sections in engineering machinery, in particular to a box assembly production line, box assembly method, production system and production method for the boom section. Background technique [0002] In the prior art, the welding process of the boom section of the foldable box-type boom frame adopts the station method to carry out the processing operation, that is, the processing system of the boom section welding has a plurality of processing stations for different processing techniques, and each processing station is located at The layout of each position in the processing site is very chaotic. The assembling and welding operations of the boom section are mixed together. In addition, since the boom section needs to be processed in one of the processing stations, it is hoisted to the next processing station in sequence for processing, and the processing is performed in sequence, and the entire processing pr...

Problems solved by technology

[0002] In the prior art, the welding process of the boom section of the foldable box-type boom frame adopts the station method for processing operations, that is, the processing system for boom section welding has multiple processing stations for different processing techniques, and each processing station is located at The layout of each location in the processing site is very chaotic. The assembling and welding operations of the boom sections are mixed together. The staff all work together at a certain station.

In addition, since the boom section needs to be processed in one of the processing stations, it is hoisted to the next processing station in sequence for processing, and the processing is performed sequentially, and the entire processing process is manually welded, resulting in low operating efficiency. The output of the section is limited, and the lifting of the jib section is a waste of time and manpower

At the same time, such a processing method leads to unsmooth operation, inconvenience to the operation, low efficiency, and inconvenient management by managers
