Disclosed are a detection device and a detection method for perpendicularity of an inner step end face to bore axis of a workpiece with a step bore relate to a special detection tool and a special detection method for part machining precision. The detection device and the detection method are applicable to large-bore work pieces, can be used for quickly and conveniently detecting data and have high reference conditions. The detection device comprises a detection gauge, a center rod, a rotary seat, a gauge connecting mechanism, a base, an eccentric wheel and a pressure rod. The detection device and the detection method are used for detecting perpendicularity of the inner step round end face to a bore of the work piece, and the inner step round end face and the bore surface are a detection reference face and a detected face respectively. The bottom surface of a lower bottom plate of the detection device serves as a positioning reference face in contact with the detection reference face. The detection device and the detection method are especially suitable for detection of inner step precision of large-sized and high-precision parts.
Description
technical field [0001] The invention relates to a special detection tool for the accuracy of machined parts and a detection method thereof, in particular to a detection device and a detection method for the perpendicularity between the inner step end face of a workpiece with a step hole and the axis of a large hole. Background technique [0002] CNC turret punch press is favored by users because of its high punching frequency and high degree of automation. With the improvement of the technical level of domestic CNC plate processing equipment manufacturers, the scale of localization has increased unprecedentedly. At present, it not only occupies a dominant position in the domestic market, but also has a substantial increase in the number of holdings in the international market. But at present, some customers report that the domestic CNC turret punch press is not as good as the imported equipment. In this regard, the applicant's research and development team, while recognizin...
