Abstract

The invention relates to the technical field of enameled aluminum wire testing, and discloses an enameled aluminum wire after-aging film elongation testing device which comprises a machine base and a machine frame fixedly installed on the top face of the machine base, a testing plate is installed on the inner wall of the machine frame in a sliding mode, and tool clamps are arranged on the inner top face of the machine frame and the top face of the testing plate. The rack is provided with a driving structure used for driving the test board to test, and two mounting seats are symmetrically and fixedly mounted on the inner top surface of the rack. Through a threaded transmission structure of the threaded sleeve and the adjusting screw rod, precise adjustment of the height of the mounting plate is achieved, through cooperation with clamping groove limiting in the moving process of the rotating sleeve, it is ensured that the mounting plate always corresponds to the center position of the tool clamp during feeding, and meanwhile the mounting plate is fixed through gravity traction of the balancing weight and magnetic attraction driving of the centering assembly. The enameled aluminum wire sample is automatically centered and straightened, so that the problem of premature fracture of a core wire caused by clamping deflection and clamping distance deviation is avoided, the error of test data is reduced, and the actual elongation of an aged skin film is accurately reflected.
