Fixing tool for steam turbine blade

Abstract

The invention relates to the technical field of steam turbine blade machining, in particular to a fixing tool for a steam turbine blade. The fixing tool comprises a rack erected on a base, a translation adjusting mechanism which is arranged on the rack and used for executing the translation adjusting procedure of the blade to be machined, a lifting mechanism which is arranged at the working end of the translation adjusting mechanism and used for executing the lifting adjusting procedure of the blade to be machined, a horizontal overturning mechanism which is arranged at the working end of the lifting mechanism and used for executing the horizontal overturning procedure of the blade to be machined, and a positioning mechanism which is arranged at the working end of the horizontal turnover mechanism, located below the horizontal turnover mechanism and used for positioning the blade to be machined. And according to the technical scheme disclosed by the invention, the problem that the assembling and welding consistency is poor due to the fact that the tool position of a stator blade is manually adjusted is solved. The fixing tool can automatically adjust the horizontal position, the height and the horizontal inclination of the stator blade so as to automatically adjust the position of a tool, so that assembling and welding are consistent, and the assembling and welding precision is improved.

Description

technical field [0001] The invention relates to the technical field of steam turbine blade processing, in particular to a fixing tool for a steam turbine blade. Background technique [0002] The baffle is an important part of the steam turbine. It divides the interior of the steam turbine into several pressure sections, allowing the steam to pass through the guide vane grid to convert potential energy into kinetic energy, and make the steam flow into the moving blade in a specified direction. The assembly quality of the diaphragm is directly related to the accuracy of the flow area, which is very important to the operating efficiency of the steam turbine. [0003] Most of the middle and low voltage partitions of the impulse unit adopt the direct welding partition structure. The existing welding process of the partition and stationary blades is to manually adjust the installation position of the blade. The installation angle of the first blade can be measured, and the subsequ...
