Abstract
The utility model discloses an internal diameter comparator. The internal diameter comparator comprises a left clamping rod, a right clamping rod, a measuring rod and a dial indicator, wherein the measuring rod is clamped at the tops of the left clamping rod and the right clamping rod by a fixing piece; upper parts of the left clamping rod and the right clamping rod are fixed together by a tightening piece; a spring is arranged between the lower parts of the left clamping rod and the right clamping rod; the side surface of the left clamping rod below the spring is connected with the right clamping rod by a fixing piece; and the dial indicator is mounted at the bottom ends of the left clamping rod and the right clamping rod. The internal diameter comparator disclosed by the utility model has the following advantages that: during using, the measurement can be made by adjusting the measuring rod to set the clock, holding the upper parts of the left and right clamping rods by hand so that the distance between the measuring rods is reduced, loosening the left and right clamping rods after entering the workpiece and recovering the original shape under the effect of the spring; and the deviation value is read by the dial indicator so as to judge whether the workpiece is qualified or not; and the small internal diameter is measured in a targeted way so that high accuracy is obtained.
Description
Technical field
The utility model relates to surveying instrument, relates in particular to inside comparator.
Background technology
Measure internal diameter and generally use the internal diameter bore gauge, but when interior electrical path length during less than 14mm, the bad use of internal diameter bore gauge can not guarantee degree of accuracy and accuracy.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of the utility model provides a kind of little internal diameter, inside comparator that degree of accuracy is high measured.
The technical scheme that the utility model adopts:
Inside comparator; It comprises left side folder rod, right folder rod, length bar and dial gauge; Said left side folder rod all has length bar through the fixture clamping with the excellent top of right folder, and top is fixed through securing member between said left side folder rod and the right folder rod, is provided with spring between the bottom between said left side folder rod and the right folder rod; The left side of said spring below presss from both sides excellent side and is connected with right folder rod through fixture, and said dial gauge is installed on the bottom of left side folder rod and right folder rod.
Said fixture is the annular knurl FLT.HD..
Said securing member is a pin.
Said right folder rod bottom is equipped with the annular knurl FLT.HD..
The beneficial effect of the utility model: during use, regulate length bar and carry out his-and-hers watches, with holding on the excellent top of left and right folder; Make the length bar distance shrinkage, unclamp behind the entering workpiece, spring action restores to the original state down; Be energy measurement, read deviate, judge that whether qualified workpiece is through dial gauge; To measuring little internal diameter, degree of accuracy is high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.Fig. 1 is the structural representation of the utility model.
Wherein, 1, left side folder rod, 2, right folder rod, 3, length bar, 4, dial gauge, 5, the annular knurl FLT.HD., 6, pin, 7, spring.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As shown in Figure 1; The inside comparator of the utility model; It comprises left side folder rod 1, right folder rod 2, length bar 3 and dial gauge 4, and left side folder rod 1 all has length bar 3 through 5 clampings of annular knurl FLT.HD. with excellent 2 tops of right folder, and top is fixing through pin 6 between left side folder rod 1 and the right folder rod 2; Be provided with spring 7 between the bottom between left side folder rod 1 and the right folder rod 2; The left side of spring 7 belows presss from both sides excellent 1 side and is connected with right folder rod 2 through annular knurl FLT.HD. 5, and dial gauge 4 is installed on the bottom of left side folder rod 1 and right folder rod 2, and excellent 2 bottoms of right folder are equipped with annular knurl FLT.HD. 5.
During use, regulate length bar 3 and carry out his-and-hers watches,, make length bar 3 distance shrinkage with holding on left and right folder rod 1,2 tops; Unclamp after getting into workpiece, spring 7 effects restore to the original state down, and promptly energy measurement is read deviate through dial gauge 4; Judge that whether qualified workpiece is, to measuring little internal diameter, degree of accuracy is high.
Claims (4)
