Automatic surfacing tool for guide vane shaft heads and use method

Abstract

The invention relates to an automatic surfacing tool for guide vane shaft heads and a use method. The automatic surfacing tool for the guide vane shaft heads is characterized by comprising a front bracket, a rear bracket, a rotating device, a front heating gun, a rear heating gun and a submerged arc welding machine, wherein the rotating device comprises a driving rotating mechanism and a driven rotating mechanism which are used for connecting the shaft heads at the front and rear ends of a guide vane; the front heating gun and the rear heating gun are installed on the front bracket and the rear bracket respectively, and correspond to the shaft heads at the front and rear ends of the guide vane in position; the submerged arc welding machine is installed above the front bracket, and is matched with the front heating gun. The use method comprises the following steps of calculating the rotating speed of the driving rotating mechanism, adjusting the front heating gun and the rear heating gun, uniformly heating the shaft heads, and surfacing the shaft heads. Preheating and surfacing uniformity of the shaft heads is improved, the guide vane is simple to turn over, subsequent surfaced positions are easy to polish, and dust pollution is low.

Description

technical field [0001] The invention belongs to the technical field of guide vane shaft head processing equipment, and in particular relates to a guide vane shaft head surfacing automatic tooling and a use method, which are suitable for large guide vanes, such as straight guide vanes or other blade shaft head surfacing welding with shaft heads. Background technique [0002] The guide vane is one of the most important parts in the water guide mechanism of the hydroelectric generator set. It is usually distributed in the water guide mechanism in a ring shape. The water flow entering the generator set is controlled by the opening and closing of the guide vane to meet the power generation capacity. Modern hydropower stations can communicate with the power grid to know the power demand in real time, so as to control the closing of the guide vanes to control the power generation, and efficiently and rationally use water energy. Therefore, when the guide vane is in the process of c...
