Abstract
A measurer for the circumferential scratch depth of a hole inside surface and shaft outside surface is provided, which relates to a measurer used for measuring the circumferential scratch depth of hole inside surface shaft outside surface. The utility model solves the problem of having no effective measurer for measuring the circumferential scratch depth of hole inside surface shaft outside surface .The measurer is composed of a digital-display dial indicator, a handle, a locking screw, a criterion rod, a measuring needle, a connection rod and a lengthened measuring rod, which is characterized in that the utility model has the advantages of that the circumferential scratch depth of hole inside surface shaft outside surface can be effectively measured.
Description
Technical field: the invention is to be used for the measuring instrument that mechanical industry component surface scratches depth survey, circumferentially scratches the measuring instrument of depth survey in particular for internal surface of hole, axle outside surface.
Background technology: at mechanical processing industry; run into internal surface of hole, this specific position scuffing of axle outside surface depth survey problem through regular meeting; these problems mainly appear in the assembling process; can be used in the measuring equipment of measuring the scuffing degree of depth at present roughly is divided three classes: a class is a contourgraph; be characterized in costing an arm and a leg; the scuffing degree of depth on energy measurement plane; but internal surface of hole, the scuffing of axle outside surface especially are subjected to positioning reference and himself structure when erecting yard is measured restriction is difficult to satisfy measurement requirement, and the data of measuring are inaccurate.Second class is mechanical three-jaw measuring instrument, be characterized in low price, easy to carry, rely on 3 contact simulation measured surfaces, and be the scuffing degree of depth on the reference measurement tested surface with the measured surface of simulation, but can only scratch the degree of depth by measurement plane, scratch the degree of depth and can't measure for internal surface of hole, this specific position of axle outside surface; The 3rd class is exactly the hand-held double tube microscope according to the principle of work development of double tube microscope, owing to be to utilize light to cut principle, through light illumination and the conversion of a series of light path, reach the measurement purpose, its structure more complicated, and the side head is two object lens that are mutually 90 degree, can't reach in the hole, can't solve the problems of measurement of the scuffing degree of depth in the hole in.
Summary of the invention: the purpose of the invention provide a kind of effective measured hole inside surface, the axle outside surface circumferentially scratch the degree of depth internal surface of hole, the axle outside surface circumferentially scratch depth calibrator; The purpose of the invention is to realize by following technical scheme:
Internal surface of hole, axle outside surface circumferentially scratch depth calibrator: be made of digital display centimeter, handle, lock-screw, baseline rod, chaining pin, adapting rod, lengthening measuring staff; Hand grip control archwise structure, make internal thread hole at upper end, and make through hole at the inner place of internal thread hole, make endoporus and make two threaded holes in the side, hole at lower end, the external thread axle is made in lengthening measuring staff upper end, internal thread hole is made in the lower end, and adapting rod one end is made through hole, and the other end is made chaining pin hole and internal thread hole; The digital display centimeter bar is inserted in the through hole of handle, fix with lock-screw, the measuring staff spiral shell that will extend is contained on the digital display centimeter bar, adapting rod is fixed on the lengthening measuring staff with lock-screw, chaining pin is installed in the chaining pin hole on the adapting rod and with lock-screw fixes, baseline rod is inserted in the handle, at its lower end endoporus, fixes with lock-screw.
The advantage of the invention: owing to adopt the baseline rod structure, datum line with baseline rod simulation measured hole surface, baseline rod and chaining pin are put into endoporus, do not scratching the position with digital display centimeter zero setting, when chaining pin when the inside surface of measured hole slowly slides, when chaining pin moves internal surface of hole scuffing place, scratching the degree of depth moves up and down chaining pin, the variation that moves up and down of chaining pin is delivered to digital display centimeter through adapting rod and lengthening measuring staff, the numeral that digital display centimeter shows changes along with the variation up and down of chaining pin, maximal value wherein is the measured value that scratches the degree of depth, effectively measure the depth value of circumferential scuffing, when the measurement axis outside surface circumferentially scratches the degree of depth, be transferred to handle lowest surface with reference field this moment is datum line, handle and chaining pin are placed on the measured axis outside surface do not have scuffing place, digital display centimeter is returned to zero, then measuring instrument is moved along the axle outside surface, scratching the degree of depth makes on the chaining pin, move down, through adapting rod, the lengthening measuring staff sends digital display centimeter to, the maximal value that digital display centimeter shows is the scuffing degree of depth, effectively measures an outside surface and circumferentially scratches the degree of depth.Simple in structure, use, easy to maintenance.
Description of drawings:
Fig. 1 is that internal surface of hole, axle outside surface circumferentially scratch the depth calibrator structural representation.
Embodiment: internal surface of hole, axle outside surface circumferentially scratch depth calibrator: be made of digital display centimeter 1, handle 2, lock- screw 3,4,7,11, baseline rod 5, chaining pin 6, adapting rod 8, lengthening measuring staff 10; Hand grip control archwise structure, make internal thread hole at upper end, and make through hole at the inner place of internal thread hole, make endoporus and make two threaded holes in the side, hole at lower end, the external thread axle is made in lengthening measuring staff upper end, internal thread hole is made in the lower end, and adapting rod one end is made through hole, and the other end is made chaining pin hole and internal thread hole; Digital display centimeter is a prior art, commercial acquisition; The digital display centimeter bar is inserted in the through hole of handle, fix with lock-screw, the measuring staff spiral shell that will extend is contained on the digital display centimeter, adapting rod is fixed on the lengthening measuring staff with lock-screw, middle shimming 9, chaining pin is installed in the chaining pin hole on the adapting rod, and fix with lock-screw, stylus tip size and length can be made different size, can and scratch the degree of depth according to endoporus and change, and chaining pin cooperates verticality to want high with adapting rod, should be in 0.005mm, guarantee measuring accuracy, baseline rod is inserted in the handle, at its lower end endoporus, fix with lock-screw.
