The invention relates to an axial grinding machine for a cylindrical rotary bending fatigue test sample. The axial grinding machine comprises a mounting frame, a fixed grinding block is arranged on the mounting frame, a first groove is formed in the fixed grinding block, and a threaded hole is formed in the fixed grinding block; and the threaded hole is in threaded connection with a connecting bolt. The grinding machine further comprises a movable grinding block matched with the fixed grinding block, the connecting bolt slidably penetrates through the movable grinding block, and a second groove matched with the first groove is formed in the movable grinding block; the first groove and the second groove form a through hole for a to-be-ground section of the test sample to pass through, and astrip-shaped abrasive paper mounting groove is formed between the fixed grinding block and the movable grinding block; and a driving mechanism used for driving the to-be-ground test sample to move back and forth in the axial direction of the through hole is arranged on the mounting frame. The test sample obtained after friction is high in precision and free of defects such as burrs, has the texture in the axial direction and accords with national standards of metal fatigue testing, grinding automation is achieved, manpower and machining time are saved, and the machine is very convenient to use.
Description
technical field [0001] The invention relates to the field of sample grinding equipment, in particular to an axial grinding machine for cylindrical rotating bending fatigue samples. Background technique [0002] At present, most metal fatigue specimens are machined by turning, which has low machining accuracy and cannot meet the national standard requirements for fatigue specimens. The more advanced processing method is grinding. This processing method can meet the high-precision requirements of fatigue samples, but the processing process is cumbersome, and it is not easy to process fatigue samples with complex structures. However, both of the above two processing methods produce circumferential textures on fatigue samples, which do not meet the requirements of the national standard for metal fatigue tests that fatigue samples have axial texture directions. Contents of the invention [0003] The purpose of the present invention is to provide an axial grinding machine for c...
