Online frame combination arrangement manner of large engineering machinery and online frame combination method

Abstract

The invention discloses an online frame combination arrangement manner of large engineering machinery, which comprises the following steps of: parallelly arranging a front vehicle frame assembling line and a back vehicle frame assembling line in the same direction; horizontally arranging a mechanical final assembly bus respectively at the front of one end of the front vehicle frame assembling line and one end of the back vehicle frame assembling line, wherein the mechanical final assembly bus is vertical to the front vehicle frame assembling line and the back vehicle frame assembling line; and arranging an underground conveyor line of which the length and extension direction are same as those of the mechanical final assembly bus in a space under the mechanical final assembly bus, and respectively arranging a vertical lifter at each of two ends of the mechanical final assembly bus. By applying the arrangement manner, the invention further discloses an online frame combination method ofthe large engineering machinery, thereby solving the disorder problem of logistics caused by the branch line frame combination of final assembly lines, reducing secondary lifting, preventing potential safety hazard probably caused by lifting rotation, reducing the labor strength of workers, improving the quality of a combined frame of the front vehicle frame and the back vehicle frame, effectively improving the final assembly efficiency of a loader, enabling the ground of a whole workshop to be clean and comfortable and the logistics to be smooth, and also reducing the cost.

Description

technical field [0001] The present invention relates to the field of assembling technology, in particular to an online frame assembly method for large-scale construction machinery, and also relates to an online frame assembly method for large-scale construction machinery. illustrate. Background technique [0002] Such as figure 1 As shown, in the field of construction machinery, the current assembly process in terms of general assembly is divided into two lines, one is the front and rear frame assembly line, and the other is the complete machine assembly line. The two lines are placed vertically, and the front frame The frame and the rear frame are first assembled on the assembly line, and then the completed workpiece is hoisted to the final assembly line by driving. Then enter the final assembly process. After the frame is assembled, the frame assembly goes online → hoisting the transmission assembly → hoisting the working oil tank, water tank... about 12 processes to co...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of the construction machinery industry in recent years, higher requirements have been put forward for the production efficiency of construction machinery loaders. The existing assembly process technical solutions need to be innovated and improved. At present, the following problems exist: ① Split-line production requires multiple lifting, production Low efficiency; ② Due to the horizontal rotation of the large frame workpiece by 90° during the lifting process; be careful when lifting

There are certain safety hazards; ②The logistics supply of the two lines is often interspersed, and the logistics is relatively chaotic; ③Due to recycling, the number of tooling fixtures on the entire line is relatively large, and the tooling equipment is relatively single, which cannot adapt to various types of loaders

④ The overall workshop looks messy and untidy. There are two large raised protective devices at both ends of the conveyor line, which affects the appearance and smooth logistics
