Description
Technical field
The utility model relates to survey instrument field, specifically a kind of huge revolving class alley diameter measurement instrument.
Background technology
Survey instrument is divided into the type such as machinery, optics, pneumatic, electronic and photoelectricity by principle of work.This sorting technique is formed by the developing history of survey instrument.But some modern surveying instruments have developed into and have adopted precision optical machinery, the principle such as optical, electrical the survey instrument combined with electronic computer technology simultaneously, therefore, this sorting technique is only applicable to the single survey instrument of principle of work, therefore current huge revolving class alley diameter measurement instrument on the market with general large-scale kind of calliper, cannot bring a lot of inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of huge revolving class alley diameter measurement instrument, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of huge revolving class alley diameter measurement instrument, comprise stationary balls connecting link fixed head, stationary balls connecting link, stationary balls, straight-bar, workpiece convolution alley, mobile steel ball, mobile steel ball connecting link fixed head, back-moving spring, mobile steel ball connecting link, dial gauge fixed head, dial gauge and dial gauge pressure head, described stationary balls connecting link fixed head, mobile steel ball connecting link fixed head and dial gauge fixed head are all located on straight-bar, mobile steel ball link bar fixed head and dial gauge fixed head are flexibly connected with straight-bar, mobile steel ball connecting link is provided with back-moving spring, mobile steel ball connecting link one end is fixed wtih mobile steel ball, the other end contacts with dial gauge pressure head, described stationary balls connecting link is fixed on stationary balls connecting link fixed head, stationary balls is fixed on stationary balls connecting link.
As further program of the utility model: described stationary balls, mobile steel ball and dial gauge pressure head are on the same line.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, easy to use, and solve current survey instrument cannot by the problem of general large-scale kind of calliper, side is measured more convenient, save measuring process, also saved the time, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of huge revolving class of the utility model alley diameter measurement instrument.
Fig. 2 is the sectional view of a kind of huge revolving class of the utility model alley diameter measurement instrument.
In figure: 1-stationary balls connecting link fixed head, 2-stationary balls connecting link, 3-stationary balls, 4-straight-bar, 5-workpiece convolution alley, 6-moves steel ball, 7-moves steel ball connecting link fixed head, 8-back-moving spring, 9-move steel ball connecting link, 10-dial gauge fixed head, 11-dial gauge, 12-dial gauge pressure head.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of huge revolving class alley diameter measurement instrument, comprises stationary balls connecting link fixed head 1, stationary balls connecting link 2, stationary balls 3, straight-bar 4, workpiece convolution alley 5, mobile steel ball 6, mobile steel ball connecting link fixed head 7, back-moving spring 8, mobile steel ball connecting link 9, dial gauge fixed head 10, dial gauge 11 and dial gauge pressure head 12, described stationary balls connecting link fixed head 1, mobile steel ball connecting link fixed head 7 and dial gauge fixed head 10 are all located on straight-bar 4, mobile steel ball link bar fixed head 7 and dial gauge fixed head 10 are flexibly connected with straight-bar 4, described mobile steel ball connecting link 9 can slide in the hole of mobile steel ball connecting link fixed head 7, mobile steel ball connecting link 9 is provided with back-moving spring 8, mobile steel ball connecting link 9 one end is fixed wtih mobile steel ball 6, the other end contacts with dial gauge pressure head 12, described stationary balls connecting link 2 is fixed on stationary balls connecting link fixed head 1, stationary balls 3 is fixed on stationary balls connecting link 2, described stationary balls 3, mobile steel ball 6 and dial gauge pressure head 12 are on the same line.
Principle of work of the present utility model is: must first by corresponding large-scale general slide calliper rule determination reference dimension before measuring workpieces, be placed in the middle of two steel balls by slide calliper rule foot-measuring, mobile steel ball 6 is pushed to mobile steel ball link bar 7, mobile steel ball connecting link 7 promotes dial gauge pressure head 12, dial gauge 11 pointer movement shows a numerical value, this numerical value is reference dimension value, first stationary balls 3 is put into workpiece revolution alley 5 during measuring workpieces, dynamic steel ball 6 is passed with have gentle hands, put it into workpiece revolution alley 5, after unclamping hand, mobile steel ball connecting link 7 promotes mobile steel ball 6 until mobile steel ball 6 and workpiece turn round alley 5 fits under the pulling force effect of back-moving spring 8, then with stationary balls 3 for the center of circle, promote straight-bar 4 with have gentle hands and do oscillating motion, mobile steel ball 6 can move along with the difference of measurement point, thus drive mobile steel ball connecting link 7, mobile steel ball connecting link 7 drives dial gauge pressure head 12 again, dial gauge 11 numerical value is changed, when mobile steel ball 6 moves to peak, the numerical value that dial gauge 11 shows is measured value, this workpiece can be obtained turn round alley diameter and survey number compared with reference dimension value.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
