Axial polishing device for grinding head

Abstract

The invention relates to the technical field of sample reprocessing, in particular to an axial polishing device for a grinding head. The axial polishing device for the grinding head comprises a supporting frame as well as a grinding head control assembly and a sample clamping assembly which are arranged on the supporting frame, the grinding head control assembly controls movement of a grinding head part, the two ends of a to-be-ground sample are both arranged on the sample clamping assembly, the grinding head part is arranged on one side of the to-be-ground sample, and a grinding pressure adjusting part enables a sample clamping part supporting plate to move close to or away from the grinding head control assembly by adjusting the position of the sample clamping part supporting plate so as to adjust the pressure between the to-be-ground sample and the grinding head. The axial polishing device for the grinding head is compact in overall structure, convenient to operate, safe and reliable, can meet the requirement for machining high-standard material samples for aero-engines, and is of great significance in improving the competitive capacity of the aviation industry in China and ensuring the quality of the aero-engines.

Description

technical field [0001] The invention relates to the technical field of sample reprocessing, in particular to an axial polishing device for a grinding head. Background technique [0002] The fatigue performance of materials is a very important index for the entire industrial field including aviation industry, nuclear power, high-speed railway and shipbuilding, especially for the engine manufacturing industry; the fatigue performance of materials is tested in the fatigue testing machine through samples Therefore, the processing of the sample is the key to whether the data of the material fatigue performance test is true; the sample used in the material fatigue performance test is generally rod-shaped, and the surface after processing is radially processed. The Nadcap material laboratory certification system, which represents the highest quality requirements of the aviation industry, takes material sample processing as a certification item. Now there are about 15 independent la...

[0003] The existing axial polishing machines all use abrasive belts as polishing materials, but according to the requirements of axial polishing, the polishing surface of the abrasive belt can only be used once, that is, the abrasive belt is required to keep moving at a constant speed along the length direction, and at the same time move along the axial direction of the sample Complete the axial polishing of the sample, but the abrasive belt cannot be fast during the axial polishing movement, otherwise the abrasive belt will fall off, resulting in the suspension of the polishing work and low work efficiency; on the other hand, the abrasive belt is pressed on the sample by the rubber roller , the pressure is adjusted by the spring, manual adjustment, low precision
