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 machine. The sampling machine includes a sampling head; the sampling head includes a threaded seat, a rotating seat and a milling cutter; the milling cutter is arranged in the guiding groove of the rotating seat and located on one side of a rotating shaft; the end head of the milling cutter faces toward to the rotating shaft, and the tail end of the milling cutter is deviated from the rotating shaft; the rotating seat controls the milling cutter to rotate around the rotating shaft, and the threaded seat is provided with a conical surface matching the rotating surface of the milling cutter; the conical surface is provided with a thread, and the side, facing toward the conical surface, of the milling cutter is provided with a tooth pattern section; and the milling cutter rotates along the conical surface, and the thread meshes with the tooth pattern section to form a screw-pair structure of a leading screw. Improvement can be performed on the clamping jaw mechanisms of existing electric drills; the milling cutter can be driven to perform forward or reverse rotation around the rotating shaft through the rotation of the rotating seat, and the milling cutter can also perform telescoping movement during rotation, so that micro-damage sampling work can be accomplished; and the sampling machine has the 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 machine. 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 with the increase in se...
