Coaxial hooking device for testing high-temperature tensile property of high-temperature alloy wire

The utility model belongs to the field of mechanics performance testing of high-temperature alloys and particularly relates to a coaxial hooking device for testing the high-temperature tensile property of a high-temperature alloy wire. The coaxial hooking device comprises a hooking component and a test sample winding component, wherein the hooking component comprises hooking threads and a cylinder; the hooking threads are formed in the head of the hooking component, the cylinder is arranged at the lower part of the hooking component, the hooking threads are in threaded connection with a tensile testing machine, the center of the cylinder at the lower part is hollowed, one side of the cylinder is opened to form an open type hole, and a coaxial positioning hole communicated to the open type hole is formed in the center of the bottom surface of the cylinder; the test sample winding component comprises a test sample winding screw rod and an anti-slide bolt; in the testing process of the tensile property of a high-temperature alloy wire sample, the test sample winding component is arranged in the coaxial positioning hole of the hooking component. According to the coaxial hooking device, the problem that the tensile property of the high-temperature alloy wire cannot be tested by virtue of an existing tensile testing machine is solved, and the reliability of the high-temperature alloy wire for engines is guaranteed; and the coaxial hooking device has continuous economic benefit.
