Problems solved by technology

[0008] One type of tool set can only meet the calibration requirements of a single aspect. However, for the outer ring of the gas turbine vane ring, the outer ring groove size is large, the wall thickness is thin, and it is easily deformed during processing, and the product requirements are high. , the shape line size changes greatly, the processing is difficult, and the size control is also very difficult
[0009] The diameter of the inner and outer circles of the outer ring of the vane ring is large, so the wall thickness is relatively thin, and the shape of the inner circle is conical, so if the conventional tool setting method is used, it is difficult to meet the processing needs of new products

Abstract

The invention discloses a processing feeler block for an outer ring race of a fixed blade ring of a combustion engine, which is used for processing the outer ring race of the fixed blade ring of the combustion engine and comprises a reference block and a plate vertically fixed on the reference block through bolts, wherein the orthographic projection of the reference block is a pentagon, one surface of the pentagon is a circular conical surface, while the other surfaces are plane surfaces; and the reference block consists of a part provided with the circular conical surface and rectangular orthographic projection, and the other part which is integrated with the part and is provided with the same circular conical surface and right trapezoid shaped orthographic projection. The processing feeler block for the outer ring race of the fixed blade ring of the combustion engine provides an accurate and reliable feeler block for processing a fixed blade ring race of the combustion engine, ensures the process precision, simplifies numerical control programs, can satisfy the corrections of cutting feed inclination angle, cutting feed length, cutting feed depth and cutting feed position simultaneously to better ensure the processing precision and quality, and saves the processing time.

Description

technical field [0001] The invention relates to the field of gas turbines in power stations, in particular to a tool setting block for processing the wheel grooves of the outer ring of the stationary vane ring of the gas turbine. technical background [0002] Usually, the gas turbine vane ring is one of the difficulties in the manufacture of the entire gas turbine due to its high processing requirements and new and complex product structure. Reasonable and correct processing and production, accurate and qualified product quality are the key to ensure the safety and high efficiency of gas turbine operation. [0003] Usually, the tool setting device is mainly composed of a tool setting block and a feeler gauge to determine the relative position of the fixture and the tool. Commonly used tool setting blocks are: [0004] Height tool setting block: tool setting when machining plane; [0005] Right angle tool setting block: tool setting when machining keyway or step surface; ...
