Abstract

The invention provides an energy storage spot-welding locating and clamping device of a stationary blade fan-shaped block welding assembly. The device comprises a base, a press block, a stop pin, a locating block and press plates. The base serves as a main component, is an arc locating surface manufactured according to the structure of the air inlet side of the welding assembly and is used for fixing a supporting piece located on the exhaust side of the welding assembly to the base through cylindrical pins. The press block, the stop pin, the locating block or the press plates are adopted on the inner arc face and the outer arc face of the welding assembly for dual inner arc locating. The clamp structure is compact; all compressing components of the clamping device are connected through screws or pin nuts; the press block and pins can be flexibly adjusted; locating is safe and reliable, and precision is high; operation is convenient and quick; repeated precision is high; the service cycle is long; maintenance is easy; the time for energy storage spot-welding clamping, spot welding and correction is greatly saved; and the production period is shortened. Thermal deformation in the assembly welding process is effectively controlled, and by means of a clamp, the assembly welding quality can be improved, and the reject ratio can be lowered.

Description

【Technical Field】 [0001] The invention belongs to the field of aeroengine manufacturing, and relates to a positioning and clamping device for energy storage spot welding of a stator blade fan-shaped block welding assembly. 【Background technique】 [0002] The current process uses metal foils to position the blades, and metal foils are used to tighten the two ends and the middle. It plays a certain role in ensuring the size of the components, but it seriously affects the appearance and increases the weight. After vacuum brazing, the middle of the components Without processing, the solder penetrates between the sheet and the parts and is difficult to remove, affecting the structure and quality of the components. [Content of the invention] [0003] In order to solve the above-mentioned problems, the object of the present invention is to provide a universal positioning and clamping device for energy storage spot welding of the stator blade segment welding assembly, which reduces the wa...
