The content of the invention
In view of this, it is an object of the invention to provide a kind of larger diameter internal bore measuring instrument, the measurement of diameter of bore can not only be met, and with simple structure, certainty of measurement advantage high.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of larger diameter internal bore measuring instrument, including measurement crossbeam, the measurement crossbeam are respectively arranged at two ends with governor motion；The governor motion includes being fixedly installed on the mounting seat of the measurement beam-end, the mounting seat is provided with the slide opening with the measurement beam vertical, traveller is provided with the slide opening, one end of the traveller is provided with postive stop baffle that is perpendicular and coordinating with interior hole end surface, and the mounting seat is provided with the position locking mechanism for locking the traveller position；In two mounting seats, one of them described mounting seat is provided with the positioning mandril parallel with the measurement crossbeam, and another described mounting seat is provided with the measurement head amesdial parallel with the measurement crossbeam.
Further, the mounting seat is provided with the axis installation through-hole parallel with the measurement crossbeam.
Further, the positioning mandril is provided with external screw thread, and the positioning mandril extends through the corresponding installation through-hole and using the spacing fixation of nut coordinated with its screw thread.
Further, the measurement head of the amesdial extends through the corresponding installation through-hole.
Further, each described mounting seat is provided with two slide openings, and traveller is equipped with each described slide opening.
Further, the installation through-hole is arranged between two slide openings.
The beneficial effects of the present invention are：
Larger diameter internal bore measuring instrument of the invention, governor motion is respectively provided with by the two ends of measurement crossbeam, in this way, can be conveniently adjusted the height of postive stop baffle using slide opening and traveller, and then the horizontal depth of beam of measurement is adjusted, to improve certainty of measurement；By installing positioning mandril and amesdial in two mounting seats at measurement crossbeam two ends, when using, positioning mandril is withstood on endoporus inwall, and the measurement head of amesdial is engaged with the inwall of endoporus, rotation measuring crossbeam, reads the full-scale reading of amesdial, you can the diameter of measurement endoporus, with simple structure, certainty of measurement advantage high.
