Description
Technical field
The utility model relates to a kind of measurer, is specifically related to a kind of major diameter measuring apparatus.
Background technology
In the production run of large-scale part, when part external diameter is less than Ф 600, adopt outside micrometer to detect its external diameter, detect simple and convenient precision high.When part external diameter is greater than Ф 600 when above, because outside micrometer size is large and heavy, operation inconvenience, measures brachium and is easily out of shape, and the data error of measurement is large, poor repeatability; Adopt special measuring tool and the pairing of his-and-hers watches part to measure, can meet the requirements of precision, but this metering system, the part of each size needs to make his-and-hers watches part and special measuring tool, and the manufacturing cost of his-and-hers watches part and measurer is high; With three seat seats, detect, need structure to buy three-dimensional lathe, detect and also need the constant temperature stand-by period simultaneously, detection time is long, the detection efficiency of wasting time and energy is low.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provide a kind of simple in structure, make easily the major diameter measuring apparatus easy to operate, precision is high, reproducible.
Major diameter measuring apparatus of the present utility model, comprises machine tool chief axis, lever indicator and magnet base, it is characterized in that: described magnet base is provided with calibration ring, and magnet base and calibration ring are by seccotine bonding connection; Described calibration ring is provided with standard annular cavity, by non-magnet_conductible material, is made as Lu's rod; Measuring staff one end of described lever indicator is provided with gauge head, and the other end is connected with machine tool chief axis; The inside surface of the standard annular cavity of described gauge head and calibration ring touches.
The utility model is simple in structure, making is easy, easy to use, do not need to unload part, only magnet base need be placed on the part of processing, the measuring staff of lever indicator is connected with machine tool chief axis, and the gauge head of lever indicator is placed in the standard annular cavity of calibration ring, rotating machine tool chief axis touches the standard annular cavity surface of gauge head and calibration ring, complete calibration location, by mobile machine tool main shaft, can complete the side amount of part external diameter, measure time saving and energy saving precision high duplication good.
