AI Technical Summary
Technical Problem
Existing fatigue test fixtures are prone to deviating the sample when dealing with rectangular cross-sectional samples, and assembly and disassembly are cumbersome, making operation difficult.
Method used
A fatigue test fixture including a connecting column, a casing component and a symmetrical clamp is designed. A threaded casing and an inner conical hole are arranged in the casing component, and the clamping blocks are assembled to form a clamping sleeve, and the positioning and clamping of the sample is achieved by positioning the bumps and the clamping slot.
Benefits of technology
It effectively prevents the sample from being offset during the fatigue test, simplifies the operation process, reduces the operation difficulty, and improves the test accuracy.

Abstract
The invention discloses a fatigue test fixture and a fatigue test device, and relates to the technical field of fatigue tests.The fatigue test fixture comprises a connecting column, a sleeve part and two symmetrical clamping blocks, and a threaded hole is formed in the connecting column; the sleeve part comprises a threaded sleeve, and the threaded sleeve is mounted in the threaded hole; the two clamping blocks are spliced to form a clamping sleeve, the clamping sleeve comprises a cylindrical section and a conical head which are connected with each other, a positioning boss is formed on the outer side of the cylindrical section, a cylindrical hole and an inner conical hole which are communicated with each other are formed in the threaded sleeve, the cylindrical section is installed in the cylindrical hole, a positioning clamping groove is formed in the hole wall of the cylindrical hole, and the positioning protruding block is installed in the positioning clamping groove. The conical head is installed in the inner conical hole, and a through groove is formed in the clamping sleeve and used for installing a sample. According to the fatigue test clamp, the sample can be positioned and clamped, the sample cannot deviate in the fatigue test process, the whole fatigue test process is simple to operate, the position of the sample does not need to be manually adjusted, and the operation difficulty is greatly reduced.
