This invention belongs to the field of bipolar plate testing technology, specifically an automatic perforation testing device for hydrogen production bipolar plates. It includes a support base with an adjustable height frame on top; a load-bearing device on top of the adjustable height frame for holding the bipolar plate; and a rotating component located at the axis on the upper surface of the load-bearing device for twisting the bipolar plate. The load-bearing device includes a metal frame with fixing rods evenly inserted into its inner wall. This device can replace manual testing. Through a scanning component at fixed points, it twists the clamped and rotating bipolar plate, thereby detecting the flatness of the perforations on the outer surface of the bipolar plate. To ensure accuracy, the rotation speed and number of rotations of the bipolar plate can be controlled, ensuring the scanning component can perform a comprehensive inspection of the bipolar plate and avoiding missed or incorrect measurements.

The utility model relates to a special tool for measuring the abrasion loss of a thermocouple of an internal mixer, and belongs to the field of testing tools for mixing tire rubber. The measuring scale is of a cylindrical structure, data scales are machined on the outer cylinder wall of the measuring scale, a screw hole is machined in the cylinder wall of the measuring scale, a locking bolt is screwed in the screw hole in a threaded fit mode, a compression spring is installed in an inner cavity of the measuring scale in the axial direction, and the outer end of the compression spring is connected with a cone. The device has the beneficial effects that data deviation caused by incorrect measurement in the measurement process is avoided, and the data for measuring the abrasion loss of the wear-resistant head of the thermocouple is accurate.
