Abstract

The invention provides portable numerical control hole boring equipment for processing a sealing surface of a valve seat of a gas turbine and an application of the portable numerical control hole boring equipment, and belongs to the field of hole boring equipment. The hole boring equipment comprises a radial control rod, a main shaft boring rod, a radial control rod driving assembly, a main shaftboring rod driving assembly and a differential assembly, wherein the main shaft boring rod is coaxially arranged on the outer side of the radial control rod in a sleeving manner; the radial control rod is driven by the radial control rod driving assembly to rotate; the main shaft boring rod is driven by the main shaft boring rod driving assembly to rotate; the differential assembly comprises a first differential bevel gear, a second differential bevel gear and a radial sliding component; and through the driving differential of the radial control rod driving assembly and the main shaft boring rod driving assembly, the second differential gear of the differential assembly rotates, and then the radial admission of a cutter is driven. According to the portable numerical control hole boring equipment disclosed by the invention, the radial control rod and the main shaft boring rod are coaxially arranged in a separating manner, so that the interference of the rotation of the main shaft boringrod and the feeding motion of the radial cutter is solved, combination and separation of the two motions are realized.

Description

technical field [0001] The invention relates to the field of boring equipment, in particular to a portable numerically controlled boring equipment for processing the sealing surface of a valve seat of a gas turbine and its application. Background technique [0002] The large-scale gas turbine control valve is responsible for the power regulation and speed regulation of the gas turbine. Its sealing surface is often corroded and eroded by high temperature and high pressure media, and the sealing surface of the valve core is worn, and its Stellite alloy sealing surface is easily damaged. [0003] At this stage, the valve seats of gas turbine control valves of D100, D145, D150, D260, D310 and other models in my country's domestic market all adopt the imported structure of Mitsubishi gas turbine, and they are all integral forging structures. The connection structure with the gas turbine body is very compact. According to the current operating conditions of the power plant, The sea...
