Technical Field
The utility model belongs to the technical field of a size measurement, in particular to carry out simple and easy measuring quick measuring device of excircle surface polishing degree of depth to steel product excircle surface polishing degree of depth.
Background
Because of the large steel solid bar or hollow pipe, after semi-finishing, the surface needs to be subjected to magnetic powder inspection, if the surface is found to have cracks, the cracks need to be eliminated by polishing with a hand grinding wheel, and then the excircle is subjected to finish machining. If the surface is polished deeply and has a large area, the finish machining of the subsequent excircle can be influenced, and even the condition that the subsequent finish machining cannot be carried out is caused.
In general, the polishing depth is measured by directly detecting the polishing position by using a depth gauge or a depth meter, and the measuring method does not consider the influence of the curvature radian of the surface of an excircle and the area of a polishing area, so that the detection result is inaccurate; if accurate measurement needs to be carried out on a three-coordinate measuring machine, the production field does not have the condition. It is very necessary to measure the depth of the cylindrical grinding rapidly and accurately.
