The utility model is characterized in that the setting surface formed by the auxiliary setting element is vertical to the movement direction of a movable measure head of the dial indicator. The utility model has the advantage that: a slight change in size of a buried pit and a hole is determined by high precise precision measuring instruments, and high precise detection requirement for the pit and the hole can be met; an operator can use the utility model conveniently and fast, and read data visually and accurately with high efficiency.
Description
Technical field
The utility model relates to the survey instrument class, particularly a kind of accurate measurement to the machining nest.
Background technology
The use of nowadays high-precision modernization, automation equipment is more and more many, and the dimensional accuracy of products that it processed is also more and more high, yet whether the size that it processed is qualified, have more high-precision survey instrument to detect.
Usually, immersing oneself in the size of nest nest, hole dimension measures with nest gauge (also crying cap high gauge).It is to identify to immerse oneself in the axial difference in height that the maximum limit of size and the minimum limit of size were produced in nest nest footpath whether the nest of institute's ream is qualified, and all then is specification product in specialized range.But the high-precision nest dimensional tolerances of immersing oneself in is too little, and the pairing step difference of counter boring diameter is also just little, and the testing staff uses the nest gauge to show because of its nil, judges by rule of thumb that just product is whether qualified and varies with each individual, and its result also is not quite similar certainly.Now, numerical control programming requires some to immerse oneself in nest, the hole dimension of nest and will provide its concrete numerical value.These require common nest rule amount not accomplish.
Detect these precision height in order to make, operating personnel are easy to use accurately, and can read and immerse oneself in the survey instrument of nest nest, the concrete numerical value of hole dimension, are about to the small mobile clear and accurate visual motion that zooms into of measuring head.Once roll in the no gap of steel ball between the inclined-plane of nest that had utilization and measuring head to do synchronous axially-movable, utilize the oblique angle difference on inclined-plane, the small movements of measuring head is zoomed into moving of groove, be able on the scale face, clearly demonstrate and immerse oneself in the groove gauge of variable quantity of the nest degree of depth.Though this groove gauge can satisfy request for utilization fully, its number of spare parts is many, the accuracy requirement height, complex structure, the processing and manufacturing difficulty is because it is very high to manufacturing and matching requirements, any one size manufacturing and rigging error of all can existing not in place influences measuring accuracy.
The utility model survey instrument has promptly solved the crucial knotty problem of immersing oneself in nest nest, the small precision measure of hole dimension.
Summary of the invention
The purpose of this utility model provides a kind of nest survey instrument, realizes immersing oneself in the accurate measurement of nest nest, the small precision of hole dimension.
Nest survey instrument of the present utility model is made up of dial gauge and the auxiliary positioning element that is fixed on the dial gauge, it is characterized in that the locating surface of described auxiliary positioning element formation is vertical with the movable measuring head direction of motion of dial gauge.
Above-mentioned dial gauge is a linear measure longimetry instrument, and the straight-line displacement of its sounding rod changes the angular displacement of pointer on dial plate into by machine driven system, and what the angular displacement on the table reflected promptly is corresponding with it nest footpath size.Above-mentioned auxiliary positioning element forms the stability that locating surface is used for increasing measured part location.
The utility model survey instrument has utilized domestic existing fine measuring instrument, uses fine measuring instrument to substitute the amplification reading principle of work of complexity, and it is simplified design both, is convenient to make processing again;
Below in conjunction with the embodiment accompanying drawing this application is described in further detail.

Specific embodiment
Referring to accompanying drawing, nest survey instrument of the present utility model is made up of dial gauge 1 and auxiliary positioning element 2, and dial gauge comprises dial plate 3, lower sleeve 4, sounding rod 5, measuring head 6 compositions; The effect of auxiliary positioning element 2 is to determine a measuring basis face or locating surface, its structure as shown in Figure 2, form by axle sleeve 8 and positioning seat 9, at the center of axle sleeve 8 and positioning seat 9 axial bore 11 is arranged, the bore of this axial bore 11 matches with the external diameter of the lower sleeve of dial gauge 4, and auxiliary positioning element 2 is fixed on the lower sleeve 4 of dial gauge 1 by securing member 7; Positioning seat 9 contains three locating detents 10, and three locating detent lower ends should guarantee at grade; The sounding rod 5 and the measuring head 6 of dial gauge stretch out locating detent 10, and the vertical range between the locating surface of locating detent 10 and the measuring head 6 is certain value H, and the H value is greater than the degree of depth of tested nest usually.During use, the measuring head 6 of this survey instrument is placed in the tested nest, allow sounding rod 5 retracting motion in lower sleeve 4, locating detent 10 is contacted with the peripheral plane of tested nest, change the degree of depth that can draw tested nest according to the reading on the dial gauge dial plate this moment.
Above-mentioned dial gauge can be mechanical dial gauge or digital dial gauge in the enforcement, adopts mechanical dial gauge, can make things convenient for fast detecting nest hole, and whether qualified determine at a glance.Adopt digital dial gauge, can read the concrete numerical value in nest footpath immediately.The measuring accuracy of dial gauge is 0.01mm.To 0.001mm, can select for use clock gauge to replace dial gauge as the fruit product accuracy requirement.
The utility model has the advantages that: utilize high-precision fine measuring instrument and reference gauge to determine Immerse oneself in nest nest, variable quantity that hole dimension is small, certainty of measurement can require choose required according to Product Precision The instrument of wanting realizes (0.01mm～0.001mm). It is intuitively more accurate than nest gauge, than groove gauge Manufacture and design simple. Its application makes the detection of the high-precision requirement such as nest, hole that concrete numerical value arranged Guarantee; Operating personnel are convenient to use, and reading out data is intuitively accurate, the efficient height.
