Problems solved by technology

[0002] During the welding process of the large frame, even if the operator welds the large frame according to the prepared process card, there will still be welding misoperations, or some instructions are not clear or specific, resulting in operational errors
In addition, large-scale racks undergo other heat treatment, surface treatment, or painting treatment directly after welding, which will cause large deformations, which will cause large errors in the installation of large racks, making it difficult to locate and cause installation problems. Various accessories on the rack need to be readjusted or scrapped, wasting costs and lengthening the manufacturing process of large equipment

Embodiment Construction

[0027] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0028] The high-precision large-scale welding process method includes the following steps:

[0029] In the first step, when designing the welding process, provide a schematic diagram of technical explanation for each welding or assembly step of the welding part of the whole machine. Work with tooling to ensure that welding operations are carried out in an orderly manner, and at the same time unify industrial operation methods;

[0030] The second step is to place the large rack on a support frame placed on a horizontal plane, and use several C-shaped clamps to clamp the large rack;

[0031] The third step is to adjust the positioning, first use the caliper to make preliminary...

Abstract

The invention discloses a high-precision welding process method of a large machine frame. The high-precision welding process method comprises the following steps: 1, a technical explanation schematic diagram is created for each welding or splicing step of a welding part of a whole machine, each welding point and requirements on the welding seam size and the wielding size of each welding point are marked in the schematic diagram, and with the cooperation of a welding tool, welding operation is conducted in order, and moreover, industrial operation methods can be unified; 2, the large machine frame is clamped by a plurality of C-shaped clamps; 3, the large machine frame is adjusted and positioned; 4, the large machine frame is positioned by a laser detector; and 5, vibration aging treatment is performed. The high-precision welding process method has the advantages that the welding process level of the large machine frame is improved, the internal stress generated after welding is eliminated, welding deformation is reduced, the production cycle of the product is shortened, deformation is guaranteed to be within a range after processing, the quality of the product is ensured, and moreover, the welding efficiency is improved, and the cycle is not influenced when the large machine frame is assembled and used.

Description

technical field [0001] The invention relates to the technical field of a large-scale frame welding process, in particular to a high-precision large-scale frame welding process. Background technique [0002] During the welding process of the large frame, even if the operator welds the large frame according to the prepared process card, there will still be welding misoperations, or some instructions are not clear or specific, resulting in operational errors. In addition, large-scale racks undergo other heat treatment, surface treatment, or painting treatment directly after welding, which will cause large deformations, which will cause large errors in the installation of large racks, making it difficult to locate and cause installation problems. Various accessories on the rack need to be readjusted or scrapped, which wastes cost and lengthens the manufacturing process of large equipment. Contents of the invention [0003] In order to overcome the deficiencies of the above-me...
