Automatic production line for diesel fork lift truck frames

Abstract

The invention discloses an automatic production line for diesel fork lift truck frames. The automatic production line comprises two sets of first hydraulic lifting roller way machines, two sets of first double-layer roller way machines, a first assembly device, a second assembly device, two sets of first fixing devices, two third welding robots, a rotating device, a first total splicing device anda second total splicing device, wherein the two sets of first hydraulic lifting roller way machines are used for conveying a left oil tank and a right oil tank correspondingly, the first assembly device is used for assembling first workpieces, second workpieces, third workpieces and the left oil tank, the second assembly device is used for assembling the first workpieces, the second workpieces, the third workpieces and the right oil tank, the two sets of first fixing devices are used for clamping the left oil tank and the right oil tank correspondingly, the two third welding robots are used for welding the left oil tank and the right oil tank correspondingly, and the rotating device is used for overturning the welded left oil tank and the welded right oil tank. According to the automaticproduction line, automatic assembling and welding of all the welding workpieces are achieved, the size precision after assembling is high, the assembling efficiency is improved, the takt time of all procedures in the frame welding process is consistent, rapid circulation is achieved, and the labor intensity of operators is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of forklift processing, in particular to an automatic production line for an internal combustion forklift frame. Background technique [0002] At present, the internal combustion forklift frame is composed of multiple welding workpieces, which are assembled and welded by multi-stations. During the welding period, the frame needs to be transported, loaded and unloaded, positioned, and welded for each welding workpiece. Multiple transports increase the burden on the operator. The labor intensity is high, the welding process takes a long time, and the work efficiency is low. At the same time, the assembly is carried out manually, which again increases the labor intensity of the operators, and the positioning deviation is large, and the dimensional accuracy after welding is low. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an automati...
