Description
Technical field
The utility model relates to the measurer technical field, more particularly, relates to a kind of survey instrument.
Background technology
Past is at metal or nonmetal during with technological formings such as cast, extruding, calendering, forging, if aperture appears in the surface, just with in the little cushion hand-hole, then with pointing the planimetric position of blocking measured workpiece, after taking out in the hole, measure the length of little pin again with Steel Ruler or vernier caliper, just the degree of depth of aperture.If surface curvature just comes the flexibility (as depicted in figs. 1 and 2) of measuring workpieces (103,203) with the chi face (102,202) of vernier caliper and Steel Ruler (101) or vernier depth gauge (201).
Above method is measured the degree of depth of aperture and the flexibility of workpiece, measuring accuracy is poor, and particularly processing capacity is little, demanding workpiece, owing to can accurately not measure the degree of depth of aperture or the flexibility on surface, so can't learn accurately whether this workpiece satisfies accuracy requirement.In addition, need behind the Workpiece shaping that has machining is carried out on the surface, at this moment just need to measure the degree of depth of aperture, see whether less than processing capacity.Greater than processing capacity, then need not to carry out the machining operation of back as if the degree of depth of learning aperture by measurement.Yet present measuring method or survey instrument can accurately not measured the degree of depth of aperture, foundation accurately are provided can't for the machining that whether can carry out the back.Discovery can not machine away defect (being aperture) fully after the processing of being everlasting, and so not only waste processing charges, but also caused the waste of freight charges and production time, thus also have to be by scrapping processing, this has just caused very big economic loss to factory.
Need a kind of survey instrument that can accurately measure defect at present badly.
