Abstract

The invention provides a tensile test device. The tensile test device comprises a base. An upper clamp, a lower clamp and a linear driving device are arranged on the base in the up-and-down direction at intervals, wherein the upper clamp and the lower clamp are used for clamping the upper end and the lower end of a test piece respectively, and the linear driving device is used for driving the upper clamp and the lower clamp to move in the directions of getting away from each other. The tensile test device further comprises a rotation driving device used for driving the upper clamp and the lower clamp to synchronously rotate in the same direction. The tensile test device comprises the rotation driving device used for driving the upper clamp and the lower clamp to synchronously rotate in the same direction, when clamped on the upper clamp and the lower clamp, the test piece can be driven by the rotation driving device to rotate around the axis of the test piece, test-piece 360-degree all-circumference scanning of the test device can be achieved, the test piece can be conveniently tested through the test device, and accurate test data can be conveniently obtained.

Description

technical field [0001] The invention relates to a testing and measuring device, in particular to a tensile testing device capable of realizing 360° rotation. Background technique [0002] The uniaxial static tensile test is one of the most widely used metal mechanical performance test methods in the industry. The tensile test can explain the common mechanical behavior of metal materials under static load and tension. [0003] The Chinese utility model patent with the authorized announcement number CN203216806U and the authorized announcement date of 2013.09.25 discloses a tensile testing machine for polymer materials. The lower end of the screw is connected to the driving device, the ball screw is equipped with a threaded flange, the threaded flange is provided with a fixture, and the base is equipped with a fixture cover corresponding to the top and bottom of the fixture, and the clamping test is carried out through the fixture and the fixture cover. The rotation of the ba...
