The inventor cooperated with Weifang University of Science and Technology on 2011.11.12 to apply for "a kind of inner diameter detection micrometer" with the application number 2011103228533. There are limitations limited by the shape and size of the workpiece, the structural coordination of the transmission parts is not precise enough, the resulting transmission error and the range of measurement functions are not ideal, especially the detection of the outer diameter cannot be carried out; at present Other special measuring tools for unidirectional measurement on the market are also too monotonous in the detection range, not comprehensive enough, and not economical in practicality, especially not convenient, fast and accurate when detecting the limit size tolerance of the workpiece, and there are certain limitations in the use function , did not apply the transmission principle, structure, material and detection function of the micrometer to the best effect

The invention relates to a bidirectional detection micrometer. The bidirectional detection micrometer is characterized in that three measuring rods and three measuring heads are arranged on a micrometer body and can be combined to measure the inner diameter and the outer diameter of a workpiece, bidirectional scale values capable of displaying the inner diameter size and the outer diameter size are arranged on the left moving measuring rod and the right moving measuring rod, and the functions of detecting inner diameters, outer diameters, square grooves, arc grooves, pipe walls, limit tolerance and other sizes are achieved while the inner diameter and the outer diameter of the workpiece are measured to the maximum. A brand-new multifunctional detection gauge is provided for the field of mechanical manufacturing and machining.
Description
technical field [0001] The invention relates to a micrometer in the field of mechanical manufacturing measurement, in particular to a bidirectional detection micrometer capable of detecting dimensions in both directions of inner diameter and outer diameter. Background technique [0002] In mechanical manufacturing and processing, due to the diversity and particularity of various types of workpieces, the measurement tools and measurement methods used for different types of workpieces are also different. Micrometer, inner diameter dial indicator, etc. It is really troublesome to check the outer diameter micrometer after measuring the inner hole with the inner diameter dial indicator, and there are also errors in multiple transfer calibrations. At present, groove vernier calipers, thread micrometers, gear normal line micrometers, wall thickness micrometers and various digital display micrometers have appeared according to the shape of the workpiece. The detection function of o...
