Valve element grinding moving trolley

The invention provides a valve element grinding moving trolley, and belongs to the technical field of nuclear island maintenance. The valve element grinding moving trolley comprises a moving table, a clamping device, a machining device and a mechanical arm; the clamping device is used for clamping and fixing the valve element and driving the valve element to rotate in the vertical face, so that the valve element rotates relative to the machining device, and then the valve element is machined through a machining tool installed on the machining device. The visual recognition device is arranged on the mechanical arm, the state of the clamping device is recognized at different positions, automatic clamping and loosening of the valve element are achieved, and the clamping device is prevented from hurting people; the measuring device is arranged on the mechanical arm to measure whether the surface roughness of the machined valve element can meet the requirement or not, so that the valve element is machined in a tar
