Background
In the field of vehicle manufacturing, a tensile test is often required to be performed on a wire harness terminal. In the prior art, a tensile test of a wire harness terminal is completed by adopting special tensile test equipment. The pull wire clamping head used by the existing tensile test equipment adopts a wedge-shaped clamping head, a clamping block clamps and locks a test piece firmly through inward pressure generated by an inclined plane mechanism during clamping, and the pull wire clamping head is convenient and labor-saving to disassemble a residual body of the test piece. However, in a tensile test, the wedge-shaped chuck often has the phenomena of 'locking' of a test piece, or 'slipping' and 'tooth breakage' of the test piece, and the like, so that a lot of inconvenience is brought to the test work.
The included angle between the outer side inclined plane of the clamping block and the vertical plane is a wedge-shaped included angle, when the wedge-shaped included angle is smaller, although the self-locking performance of the chuck is good, the test piece is easy to clamp and lock firmly, the tighter the clamping and the firmer the locking are, the more difficult the disassembly of the test piece residue is, and the phenomenon of 'locking' is caused. However, if the included angle of the wedge is large, the expansion amount of the clamping stroke of the bayonet is large, the test piece is easy to clamp and disassemble, but the self-locking performance is poor, and the test piece is easy to slip in the bayonet. The clamp heads corresponding to wedge-shaped included angles are often used for wire harnesses of different thicknesses and different materials, so that balance can be achieved between locking and slipping, and the tensile test equipment is high in cost due to the fact that the plurality of clamp heads need to be replaced correspondingly when the tensile test equipment is applied to different wire harnesses.
