In addition, during the detection of the titanium alloy bar, the synchronization of the two clamps pulling the two ends of the titanium alloy bar to move can be ensured;

[0033] 4. When testing, the staff can control the hydraulic cylinder to drive the base to descend. The descent of the base can squeeze the lifting plate so that the inclined push rod pushes the linkage straight tooth condition to move, which can provide power for the position adjustment of the clamp. In addition, when testing the yield strength, the two sliders 9 drive the two clamps 16 to move in the opposite direction. Through the reverse movement of the clamps 16, the two ends of the titanium alloy material can be resisted, effectively ensuring that the middle of the titanium alloy is located at the lower end of the test device 31, thereby ensuring the quality of the yield strength test.

[0034] 5. When the linkage spur gear condition moves, the linkage gear member meshing with it can drive the second rocker member to move. The two linkage gear members meshing with each other in the connecting member can make the first rocker member and the second rocker member move to push the horizontal connecting rod member to rise, which can drive the clamp member to rise.

The clamps 16 move in the opposite direction to contact the two ends of the titanium alloy material, effectively ensuring that the middle of the titanium alloy is located at the lower end of the test device 31, and ensuring the quality of the yield strength test. The two motors 17 are controlled by the controller 2 to operate. The two motors 17 drive the two worms 18 to rotate. The two worms 18 drive the two worm wheels 19 to rotate. The two worm wheels 19 drive two of the screws 20 to rotate. The two screws 20 drive two of the sprockets 21 to rotate. The two sprockets 21 drive the other two sprockets 21 synchronously through the two chains 22. The four sprockets 21 drive the four screws 20 to rotate synchronously, the four screws 20 push the four threaded sleeves 23 down, and the four threaded sleeves 23 drive the two pressing pieces 24 to press and fix the two ends of the titanium alloy bar, so that the two ends of the titanium alloy bar can be clamped on the two clamps 16. When in use, the staff can place the titanium alloy bar on the base 5. At the same time, the upper ends of the base 5 and the clamps 16 are arranged flush. Through the coordinated operation of the lifting mechanism and the resistance mechanism, a gap can be generated between the base 5 and the clamps 16, which is convenient for the yield strength test of the titanium alloy bar. The controller 2 controls the second The cylinder assembly 30 drives the test device 31 to descend, and the test device 31 contacts the upper end of the titanium alloy rod for detection. The test device 31 transmits the detection data to the data display 3 for display, and when the middle of the titanium alloy material is pressed, the titanium alloy material will be deflected, and the straight-line distance between the two ends of the titanium alloy will change. This will cause the clamp 16 to drive the sliding shaft part 44 to squeeze the compression spring part 42 to move, which can adapt to the change in the distance between the two ends of the titanium alloy material, avoid the situation where the yield strength detection error is large due to the inability to adjust the distance between the two ends, and improve the accuracy of the detection.
