The invention discloses a spliced welding method for a speed reduction machine seat, and relates to the technical field of welding. By using a spliced welding device for the speed reduction machine seat, the operation method comprises the following steps of: putting a bottom plate of the speed reduction machine seat between a mould core of the spliced welding device of the speed reduction machine seat and a baffle plate; putting a positioning plate on the mould core; allowing two side plates to be close to the two sides of the mould core and press against the bottom plate and a base plate; fixing the two side plates on two sides of the mould core by a compaction device; putting a bent board between the mould core and a pressing block to start a hydraulic cylinder; fixing the bent board at one end of a curved surface of the mould core through a hydraulic cylinder by the pressing block; pushing the mould core by the pressing block to fix the bottom plate on the baffle plate; performing spliced welding on the bent board, the side plates, the bottom plate and the positioning plate; respectively placing the two reinforcing plates on two sides of the positioning plate; and performing spliced welding on the reinforcing plates, the side plates and the bottom plate. Compared with the prior art, the splicing is finished by the spliced welding device for the speed reduction machine seat, so that the spliced device is good in uniformity of the appearance size, can be automatically welded, and improve the production efficiency.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a method for tailor-welding a speed reducer base of an excavator crawler beam frame. Background technique [0002] The reducer base is one of the basic parts of the reducer, which supports and contains the internal parts to maintain the correct mutual positional relationship. There is a speed reducer base of an excavator crawler beam frame, which is a steel structure composed of a base plate, a semicircular bent plate located on the base plate, side plates and positioning plates on both sides of the bent plate and other parts welded. At present, this kind of reducer base is assembled and welded by hand on a platform with various positioning. The method of manual tailor welding is: 1. Put the positioning plate of the reducer base on the positioning platform; 2. Put the bent plate in and assemble it with the positioning plate. After correction, perform tailor welding between the ...
