Problems solved by technology

[0006] (1) The traditional micro-damage sampling equipment cannot satisfy the detection of thicker sampling thickness, different positions, crack properties, etc.
[0007] (2) The sampling size of the commonly used core drills in the industry is too large, and the heat is severe, which destroys the performance of the material to be inspected. It cannot be applied to the sampling performance of thin-walled or cracked equipment in steel, shipbuilding, metallurgy, nuclear power and petrochemical industry. detection
[0008] (3) The cylindrical cutter of the punching and grinding type sampling machine puts forward extremely high requirements on the material and manufacturing process, and the existing materials and processing technology are difficult to process the cutting tool that meets the requirements

Embodiment 1

[0041] A punching, sampling and grinding tool with a structure such as figure 1 As shown, the cutting tool includes a blade 1 and a shank 4 integrally arranged at the bottom end of the blade body 3. The bottom end of the cylindrical blade 1 is fixedly connected with the shank 4 through the blade body 3, and the top end of the blade 1 is opened with a cylinder inward. The inner and outer walls of the cylindrical tool are cylindrical.

[0042] In the actual sampling operation (such as when sampling the outer surface of the pressure vessel), screw the tool holder 4 into the motor spindle of the fixed sampling machine, and the motor spindle provides the cutting power while the servo motor provides a continuous The downward low-speed micro-feed motion makes the cutting tool have both autorotation motion and downward feed motion, which can gradually cut a complete cylindrical material from the sampling object.

Embodiment 2

[0044] Using a cutting tool similar to that of Example 1, the difference is that the outer wall of the straight cylindrical tool of this embodiment is cylindrical, and the bottom end surface of the cutting edge part 1 of the straight cylindrical tool is inlaid with synthetic diamond 7, and the key cutting part is covered Emery coating 2. The diameter of the diamond particles is 0.2mm to 2mm, and the bottom end is inlaid with a synthetic diamond 7 every 5mm to 25mm. The area covered by emery is extending from the cutting edge to the bottom of the tool, and the extension length covered by emery is 10 to 80 mm. The particle size of the covered emery is any value between 30 mesh and 250 mesh.

[0045] A preferred embodiment is that during the sampling process, cooling liquid is added to make grinding smooth and protect the tool. A cooling fluid channel is arranged in the center of the knife handle, and a shielding baffle is connected to the end of the channel, and the shielding baf...

Abstract

The invention belongs to the technical field of testing and sampling equipment, and discloses a grinding, punching and sampling tool for obtaining a cylindrical specimen and a using method of the grinding, punching and sampling tool. The bottom end of a cylindrical tool is fixedly connected with a tool handle through a tool body; a spiral groove is formed in the inner wall of the cylindrical tool,a tool edge at the top end of the cylindrical tool is hardened, wear-resistant coatings are prepared on the inner and outer surfaces of the tool, a cooling liquid channel is formed in the center of the tool handle, and a shielding plate is fixed inside the cylindrical tool outside the cooling liquid channel by screws. The tool has a unique cylindrical structure, and the top of the cutting edge and the inner and outer surfaces are covered with the wear-resistant coatings. The structure is first applied to drilling and sampling, adopts grinding mechanism, and is initiative. The cutting tool hasthe advantages of being small in size, easy to carry and install and the like, and can cut off the complete cylindrical sample which is not affected by heat/machinery and has diameter of 10-100 mm and height of 10-80 mm.

Description

Technical field [0001] The invention belongs to the technical field of detection and sampling equipment, and in particular relates to a grinding and perforating sampling tool for obtaining cylindrical test blocks and a use method thereof. Background technique [0002] At present, the closest existing technology: At present, many industries in my country are in mechanical performance testing, organization analysis, defect qualitative and other aspects, especially steel plates, special equipment, pressure pipelines. In order to ensure product quality, service safety, and confirmation of the nature of defects, large-scale destructive sampling was used for routine performance analysis in the past. Destructive sampling and routine performance testing are not only time-consuming and labor-intensive, but also very costly, which greatly wastes resources. How to quickly take out a small sample for various performance testing and analysis is an urgent need of many industries. [0003] A se...
