Torque loading test fixture for curved surface

Abstract

The invention discloses a torque loading test fixture for a curved surface. The torque loading test fixture comprises chucks (1), a cavity (2) and a fixture seat (3), and is characterized in that thechucks (1) are respectively arranged at two ends of the fixture seat (3). The torque loading test fixture is low in cost, convenient to use and simple in structure.

Description

technical field [0001] The invention belongs to the technical field of torsion tooling, in particular to a curved surface loading torsion test tooling applied to a part with a curved loading end surface. Background technique [0002] Torsion tooling is an auxiliary tooling widely used in torsion tests. Usually, the cavity of the torsion tooling will restrict two or more degrees of freedom of the test part, so that the part can rotate. If it needs to be loaded, it can be loaded with a loading washer. However, this fit mode is usually applied in the torsion test where the loading end surface of the part is a plane. Its disadvantage is that when the loading surface of the part is a curved surface, the contact area between the plane loading gasket and the part is very small, which will affect the test during the loading process. Accuracy, damage to the contact surface of the parts will cause the test to fail, resulting in untrue data and inconvenient loading and unloading. Con...
