Example Embodiment

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown in the figure, the frame tailor-welding device for construction machinery includes a joint assembly line 1 and a welding assembly line 2; the assembly point assembly line 1 and the welding assembly line 2 are equally divided into several stations, which can be set according to actual needs. Generally, the assembly point assembly line 1 It is divided into five stations, the welding line 2 is divided into four stations, and the welding line 2 has two sets, which is a two-line parallel structure, which can realize the balance of splicing points and welding processes; such as figure 2 As shown, the assembly line 1 includes a transfer trolley 11 and a circulating line body 12, and the transfer trolley 11 is connected with the circulating line body 12; such as image 3 As shown, the welding line 2 includes a reciprocating line body 21, a turni...

Abstract

The invention discloses a splice welding device for a vehicle frame used for engineering machinery and a splice welding method for the vehicle frame. The splice welding device comprises a splice point production line and a welding production line which are both divided into a plurality of work positions respectively. The splice point production line comprises a transfer vehicle and a circulating type line body which are connected. The welding production line comprises a reciprocating type line body, an upender, transfer trolleys and a lifting platform. The transfer trolleys are connected with the reciprocating type line body. The welding production line is arranged on the side in the advancing direction of the circulating type line body of the splice point production line. The splice point production line is connoted with the welding production line through a transition device. The transfer trolleys all run on the ground. The whole production line foundation is simple, and not a large amount of rectification needs to be conducted on the foundation, so that investment is less. The work positions are divided for splice welding of the vehicle frame, and a climbing device, a vehicle frame overturn device, a lifting device and other devices which are matched with the work positions are designed, so that linearization production of vehicle frame splice welding is achieved, and the quality problems of missing splice and missing welding in the splice welding process are solved.

Description

technical field [0001] The invention relates to a tailor-welding device and a tailor-welding method thereof, in particular to a tailor-welding device of a frame for construction machinery and a tailor-welding method thereof. Background technique [0002] Linearized production is very common in modern factories. The entire production line is divided into several stations, and each station is assigned a fixed position to standardize the on-site operation order, improve the business proficiency of workers, and eliminate the buffer between production processes by realizing single-piece flow. [0003] At present, the frame welding production in the production workshop adopts the principle of process layout. A single person is responsible for a single process. The process content is complicated, and there are missing stitching and welding. There is no special device for frame flipping. Logistics and efficiency issues. [0004] The production line in the prior art is generally of ...
