Description

Technical Field

[0001] The utility model relates to the technical field of rotary structural component processing, in particular to a rotary structural component welding device. Background Art

[0002] A rotary structure usually refers to a mechanical structure that can perform rotational motion. In mechanical engineering, rotary structures are widely used in mechanical equipment that requires rotational motion, such as construction machinery, ship equipment, light industrial machinery, etc. During use, the rotary structural parts may produce stress concentration due to the action of various forces, which has a great impact on the strength and service life of the material. In order to reduce this stress concentration, the rotary structural parts usually need to be welded, which can not only improve the strength and performance of the overall structure, but also improve work efficiency and ensure product quality.

[0003] According to the search, the Chinese patent document, announcement number: CN203887447U, discloses a rotating structural member welding device, which can effectively control the key dimensions of the rotating structural member in terms of parallelism and verticality during welding by setting a positioning seat with positioning holes symmetrical about the center of the frame tooling on the frame tooling, so that the diagonal dimensions of the rotating structural member and the dimensions of the upper and lower assembly connection holes can be accurately controlled. However, in actual use, since the frame tooling is an integrated connection, continuous welding cannot be performed when it drives the structural member to rotate, thereby reducing the quality of the product; in addition, the device fixes the rotating structural member to the positioning seat by using bolts and other fixings, which is not only inconvenient to disassemble and assemble, but also reduces the overall work efficiency of the device.
