Strength testing device for powder metallurgy component

The invention relates to the technical field of strength testing of metallurgical parts, and particularly discloses a strength testing device for a powder metallurgical part, which comprises an experimental machine main body and a part adapting mechanism, and the part adapting mechanism is arranged on a clamping seat I and is used for adapting to a to-be-tested part; and the filling mechanism is arranged in the clamping piece seat I and is used for protecting the tubular piece to be tested. According to the invention, the to-be-detected powder metallurgy pipe is clamped between the first clamping seat and the second clamping seat, the powder metallurgy pipe is clamped under the control of the fitting mechanism, the powder metallurgy pipes in different shapes are clamped and fixed through the fitting mechanism, and the powder metallurgy pipes are automatically inserted into the cylindrical powder metallurgy pipe through the filling mechanism. On one hand, positioning of the powder metallurgy pipe is facilitate
