Abstract
The invention discloses a section bar surface coating abrasion resistance detection mechanism which comprises a supporting frame and a sand containing funnel arranged at the upper portion of the supporting frame. A discharging port of the sand containing funnel is connected with the upper end of a guide tube, and a workpiece is arranged under the lower end of the guide tube. By the adoption of the structure, the section bar surface coating abrasion resistance detection mechanism has the advantages that the abrasion resistance of a section bar surface coating is accurately measured by abrading through the section bar surface coating, and sand material concentricity is high; inclination angle adjustment of a section bar plate is facilitated through a rotary shaft structure, and installation of the section bar plate is also facilitated; a positioning needle is used for ensuring that the contact heights from freely dropping sand materials to the section bar plate are equal during each-time sample testing, and errors caused by height difference are decreased; the guide pipe prevents wind power from influencing the freely dropping sand materials. A lifting mechanism enables a sand material weighing mechanism to rise to the position of the sand containing funnel, and the sand materials in the sand material weighing mechanism flow into the sand material weighing mechanism to achieve circular usage.
