Problems solved by technology

[0006] Existing micro-damage sampling devices mainly use pneumatic cutting, electric spark cutting, and spherical or semi-spherical milling cutter cutting; however, these sampling devices generally have complex structures, poor stability, and insufficient strength of arc-shaped cutters. The operation is inconvenient, the surface of the sampled part is uneven, and it needs to be polished again, and the workload is large; especially for some high-hardness alloy materials, it is difficult to adapt

Abstract

The invention relates to a sampling device and a sampling method. The sampling device includes a sampling machine and a fixing rack; the sampling machine includes a sampling head and a rotary driving mechanism; the rotary driving mechanism is arranged on the fixing rack; and the fixing rack is arranged on a connecting mechanism used for fixedly connecting with a to-be-sampled component; the sampling head includes a threaded seat, a rotating seat and a milling cutter; the rotating seat is in transmission connection with the rotary driving mechanism; the milling cutter is arranged in the guiding groove of the rotating seat; the threaded seat is provided with a conical surface; the milling cutter surface is provided with a tooth pattern section; and the tooth pattern section meshes with the thread of the conical surface to form a screw-pair structure of a leading screw. The fixing rack can stably fix the sampling machine on the component; a cutting edge can perform telescoping and moving when rotating around a rotating shaft; and thus, micro-damage sampling can be realized, and the device and method have advantages of being simple in structure, convenient in operation, good in stability, flat in sampled part and easy in welding and repairing after taking.

Description

technical field [0001] The invention belongs to the technical field of component surface sampling, and in particular relates to a sampling device and a sampling method. Background technique [0002] At present, with the development of the modern energy industry, especially the development of large-scale coal-fired power generation units towards more efficient supercritical units, new materials are continuously applied to large-scale boiler equipment; due to these new heat-resistant steel materials (such as P92, P122 etc.) have not yet fully grasped the service characteristics, so it is necessary to conduct a full-life performance evaluation of the components. At the same time, with the country’s requirements for clean energy development, it is necessary to carry out feasibility studies and technical transformation of some in-service units to improve operating parameters, and these in-service units urgently need to carry out safety performance evaluation and life extension wi...
