A double-station robot automatic welding production line for milling drum tool holders

Abstract

The invention relates to the technical field of pavement maintenance equipment, in particular to a double-station automatic welding production line of a milling drum knife holder robot; and the double-station automatic welding production line of the milling drum knife holder robot comprises a spot welding station, an all-welding station and a material transfer device. The spot welding station and the all-welding station are respectively arranged at the two ends of the material transfer device; and the material transfer device moves between the spot welding station and the all-welding station. The double-station automatic welding production line of the milling drum knife holder robot adopts a double-procedure welding process of spot welding and all welding to integrate a multi-robot collaborative manufacturing technology, so that the welding automation degree is largely increased, the welding quality and stability of a milling drum knife holder are effectively improved, the number of operators is reduced, and the adverse impact on environments and human bodies is eliminated.

Description

technical field [0001] The invention relates to the technical field of road surface maintenance equipment, in particular to a double-station milling drum tool holder robot automatic welding production line. Background technique [0002] Road surface milling machine is one of the main equipment for asphalt concrete pavement maintenance and construction. It is mainly used for the excavation and renovation of asphalt concrete surface layers such as highways, urban roads, airports, freight yards, etc. Defect removal. The milling drum is one of the important parts of the milling machine, which consists of a drum, a cutter seat and a cutter head. During the working process, the transmission device of the milling machine drives the milling drum to rotate at a high speed, and the cutter head of the milling drum is in direct contact with the ground to complete road milling. [0003] The cutter seat of the milling drum is connected to the drum by welding process. At present, there ...

AI Technical Summary

Problems solved by technology

At present, there are still the following shortcomings in the welding process of domestic milling drum tool holders: 1) Low degree of automation

Most domestic enterprises use manual welding to complete the welding of the tool holder, and some enterprises use simple tooling to assist the welding of the tool holder, and the welding processing method has a low degree of automation

2) The product quality is unstable, and the welding process of large-scale equipment has extremely high technical requirements for workers

The welding quality of the tool seat cannot meet the technical requirements of the main parameters such as the helical arrangement of the milling drum, the length of the knife output, and the rotation angle. The welding quality is poor in consistency, which is likely to cause rapid tool wear, high power consumption, and increased vibration of the whole machine when the milling machine is working. , poor road surface flatness and poor trimming performance, etc., seriously affect the working efficiency of the iron planer and the technical performance of the whole machine

3) The labor intensity of workers is high and the production environment is harsh

The labor intensity of large-scale equipment welding is high, and the welding environment is harsh. Welding fume and radiation seriously affect the physical and mental health of workers
