Abstract
The utility model discloses a measuring instrument and especially provides an inter-hole center distance measuring instrument. The utility model provides an inter-hole center distance measuring instrument capable of measuring the center distance between holes once. The measuring instrument comprises a main ruler rod and a vernier. The vernier is arranged on the main ruler rod in a sliding way. The end part of the main ruler rod is provided with a fixing card. A screwing nut is arranged on the vernier. The vernier and the fixing card are respectively provided with a measuring claw with a tapered contour. By arranging the measuring claws with tapered contours, the measuring instrument is enabled to measure the center distance between two holes by directly making the measuring claws placed inside the two holes to be measured and then displaying the readings of the vernier on the main ruler rod. In this way, multiple measuring operations are no longer necessary. Meanwhile, the measuring instrument reduces the measuring errors and further increases the efficiency.
Description
Technical field
The utility model relates to a kind of survey instrument, especially a kind of pitch of holes measuring instrument.
Background technology
In machinery production processing, sometimes need precisely to draw the centre distance of different pore size, but vernier caliper often is being easier to for lienar for size ratio, and is needing the multiple conversions size to draw final size for the position that does not detect, very easily produce error.Need to survey with vernier caliper the distance in two holes when the measured hole spacing, survey the diameter in two holes again, then calculate the centre distance in two holes, so repeatedly measurement must cause the increase of error.
The utility model content
Technical problem to be solved in the utility model provides a kind of pitch of holes measuring instrument of once measuring pitch of holes.
The pitch of holes measuring instrument that its technical matters that solves the utility model adopts, comprise primary division rod and vernier, described vernier is slidingly arranged on the primary division rod, the end of described primary division rod is provided with fixed card, be provided with on the described vernier and screw nut, be provided with the tapered measuring jaw of profile on described vernier and the fixed card.
Further be, described measuring jaw comprises at least two claws and spring, and mounting groove all is set on described vernier and the fixed card, and described measuring jaw is installed on the mounting groove, and described claw and mounting groove are slidingly matched, and described spring fitting is between the claw of measuring jaw.
Further be that described measuring jaw comprises two claws.
The beneficial effects of the utility model are: owing to be provided with the tapered measuring jaw of profile, therefore when measuring two hole centre distance, directly measuring jaw is placed in two holes to be measured, and then read vernier and get final product at the reading of primary division rod, so just needn't repeatedly measure again, reduce measuring error, also improved efficient simultaneously.Measuring jaw comprises at least two claws and spring.At this moment, measuring jaw is being placed to when treating in the gaging hole, and claw can adaptive motion, thereby so that the integral diameter of measuring jaw and the diameter coupling for the treatment of gaging hole, even two bore dias surveying are inconsistent, measuring jaw also can be by the adaptive motion of claw and separately the diameter coupling for the treatment of gaging hole.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model;
Parts, position and numbering among the figure: primary division rod 1, vernier 2, measuring jaw 3, mounting groove 4, fixed card 11, screw nut 21, claw 31, spring 32.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises primary division rod 1 and vernier 2, described vernier 2 is slidingly arranged on the primary division rod 1, the end of described primary division rod 1 is provided with fixed card 11, be provided with on the described vernier 2 and screw nut 21, be provided with the tapered measuring jaw of profile 3 on described vernier 2 and the fixed card 11.The tapered measuring jaw 3 of profile mainly be for guarantee measuring jaw 3 be placed to behind gaging hole can with the central lines for the treatment of gaging hole, the measuring jaw 3 on the fixed card 11 and the centre distance between the measuring jaw 3 on the vernier 2 are two centre distance for the treatment of gaging hole like this.In use, selected two holes that need to measure centre distance, measuring jaw 3 on the fixed card 11 is placed in one in the hole, then the measuring jaw 3 on the vernier 2 is placed another hole, press down fixed card 11 and vernier 2, so that measuring jaw 3 separately overlaps with each self-corresponding centerline hole, namely measuring jaw 3 applying hole inwalls get final product.Owing to set in advance measuring jaw 3 on the fixed card 11 and the range reading between the measuring jaw 3 on the vernier 2 on the primary division rod 1, therefore, can read measuring jaw 3 on the fixed card 11 and the centre distance between the measuring jaw 3 on the vernier 2 this moment, namely the centre distance between two holes.Said method need not to take multiple measurements, and has avoided repeatedly measuring the error that causes, and needn't calculate again, has made things convenient for operation.
Hole for the self-adaptation sizes, as shown in Figure 2, described measuring jaw 3 comprises at least two claws 31 and spring 32, on described vernier 2 and the fixed card 11 mounting groove 4 is set all, described measuring jaw 3 is installed on the mounting groove 4, described claw 31 is slidingly matched with mounting groove 4, and described spring 32 is installed between the claw 31 of measuring jaw 3.Claw 31 mutual combinations can form conical measuring jaw 3, when not using, claw 31 separates under the effect of spring 32, claw 31 itself has the inclined-plane, measuring jaw 3 is being placed to when treating in the gaging hole, so that claw 31 is to measuring jaw 3 the center displacements, until each claw 31 is bonded to each other, two of claw 31 operated by rotary motion get final product.Adopt can adaptive measuring jaw 3 after, measuring jaw 3 can be according to the big or small auto scaling in hole, even two holes not of uniform size also can once record its centre distance.
