Abstract
The utility model relates to a vernier caliper which is realized by improving on the basis of the existing common vernier caliper. The utility model is characterized in that two inner measuring jaws are provided with two screw holes, and auxiliary measuring jaws are assembled by screw nails. The utility model has the advantages of reasonable design, simple structure, easy fabrication, low cost, high precision and convenient use and can be used for measuring step holes and holes which are internally provided with solid bodies besides the functions of the common vernier caliper.
Description
The utility model belongs to the survey instrument of component of machine, relates to a kind of vernier caliper.
At present, the hole of interior band solid, for example the dead eye on body or the shell part two survey faces in process, has the floating boring rod solid in it.This endoporus all can't be measured with existing slide calliper rule, micrometer inside caliper.Usually all is by the workman who knows a thing or two, adopts external callipers to measure, this measuring method, poor accuracy, precision are lower, waste product often occurs, cause waste.
The purpose of this utility model provides a kind of novel vernier caliper, and this vernier caliper is manufactured easily, not only can keep the function of common calliper, and the measurement in the hole of band solid in can be used for, and precision is guaranteed, uses easy to operately, is easy to popularize.
The utility model is to improve to realize that it comprises two interior measuring claws on the basis of existing common calliper, and its main points are all to have two screws on two interior measuring claws, and are equiped with the subsidiary pawl by screw.
Below in conjunction with accompanying drawing the utility model is elaborated:
Accompanying drawing is a front view of the present utility model.
With reference to the accompanying drawings, 1 is the interior measuring claw of vernier caliper among the figure, on two interior measuring claws 1 two screws is arranged all, is equiped with subsidiary pawl 3 by screw 2.
During the hole of band solid, at first two interior measuring jaws 1 of vernier caliper are close in being used to measure, this moment, the subsidiary pawl 3 also was close to; Again with the zeroing of the dial gauge on vernier caliper position, utilize afterwards outside micrometer measure two subsidiary pawls apart from size, and write down numeral, at this moment just available this chi is internally measured with the hole of solid, its survey measurements adds above-mentioned outside micrometer reading value, is this hole physical size.
The utility model is reasonable in design, and is simple in structure, manufactures easy.Except that the function that keeps existing common calliper, the measurement of the hole of band solid and stepped hole etc. in also can be used for, precision is guaranteed, and is easy to use, is easy to popularize.
