Sand making machine rotor tailor-welded double-layer positioning template tool and tailor-welded process of sand making machine rotor

Abstract

The invention relates to the technical field of welding tools, in particular to a sand making machine rotor tailor-welded double-layer positioning template tool and a tailor-welded process of a sand making machine rotor. The sand making machine rotor tailor-welded double-layer positioning template tool is characterized in that the sand making machine rotor tailor-welded double-layer positioning template tool comprises a bottom plate, a main shaft is arranged on the bottom plate, a positioning disc, a positioning gland and an end cover sleeve the main shaft, a plurality of cushion blocks for supporting an upper end plate are detachably arranged on a lower end plate of the rotor, a first wedge block mechanism for clamping the positioning gland and a second wedge block mechanism for clampingthe end cover are further arranged on the main shaft, a first positioning template and a second positioning template sleeve the main shaft, the first positioning template and the second positioning template are each of a double-layer structure, the second wedge block mechanism can further be used for clamping the first positioning template and the second positioning template, and the sand making machine rotor tailor-welded double-layer positioning template tool further comprises a single-layer positioning template assembly. According to the and making machine rotor tailor-welded double-layer positioning template tool and the tailor-welded process of the sand making machine rotor, simple and practical overall structure, fast and accurate positioning and high precision are achieved, splicingefficiency is effectively improved, meanwhile, the overall verticality requirement can be ensured, and the overall welding quality can be ensured.

Description

technical field [0001] The invention relates to the technical field of welding tooling, in particular to a sand making machine rotor tailor welding double-layer positioning model tooling and a sand making machine rotor tailor welding process. Background technique [0002] The rotor is an important part of the sand making machine. The material is usually fed into the middle of the high-speed rotating rotor, and then after being accelerated, it is thrown out from the outer extension of the rotor due to centrifugal force. The accelerated material is crushed when it hits the outer wall of the crushing chamber. . [0003] The rotor usually includes an upper end plate, a lower end plate, and a plurality of fixed plates and fixed blocks between the upper end plate and the lower end plate, and these parts are tailor-welded. During the tailor-welding process of the parts, positioning is required. Considering that drawing a line for positioning, the positioning accuracy cannot be gua...

Problems solved by technology

[0003] The rotor usually includes an upper end plate, a lower end plate, and a plurality of fixed plates and fixed blocks between the upper end plate and the lower end plate, and these parts are tailor-welded. During the tailor-welding process of the parts, positioning is required. Considering that drawing a line for positioning, the positioning accuracy cannot be guaranteed if the line is drawn for positioning. There are also positioning templates for positioning, but they are all single-layer. The disadvantage of single-layer is that for some strip-shaped parts In other words, the bottom of the welded part is positioned, but the positioning of the upper part will be affected, and the verticality requirements of the welded part cannot be well guaranteed. If it is necessary to better ensure the verticality, the thickness of the single-layer positioning template is It has to be thicker, impractical, costly, and inconvenient to use. The rotor produced by the original positioning method has low positioning accuracy in the splicing process, which reduces the quality of the finished rotor. In addition, the positioning speed is slow. Seriously affects the tailor welding speed, resulting in low efficiency of rotor tailor welding
