Grading tool for measuring rocker arm and rocker arm grading system

The utility model relates to a grading tool for measuring a rocker arm and a rocker arm grading system. The rocker arm grading system may include a grading tool. The grading tool may be used with a rocker arm to measure the profile of the rocker arm and determine the resulting valve lift. The grading tool can include: a rocker arm clamp including a pivot pin and a valve pin; a cam clamp that may include a cam arm; a cam pin, which may be mounted on the cam arm. And the rocker arm is detachably mounted on the rocker arm clamp. The rocker arm may comprise a radius on the bearing surface. The cam edge of the cam-pin may be pressed against the bearing surface. At least one measuring device may be configured that includes a wavelength emitting device paired with the wavelength detecting device and is configured to measure a radius of the bearing surface relative to the pivot pin. 本实用新型涉及用于测量摇臂的分级工具和摇臂分级系统。摇臂分级系统可包括分级工具。该分级工具可与摇臂一起使用，以测量摇臂的轮廓，并确定由此产生的气门升程。该分级工具可以包括：摇臂夹具，它包括枢轴销钉和气门销钉；凸轮夹具，它可以包括凸轮臂；凸轮销，它可以安装在凸轮臂上。摇臂可
