Abstract

The utility model provides an utensil is examined to special measurement of annular diameter in part, it includes one yuan of annular measuring ring, install bore dial indicator and interchangeable gauge head on measuring ring's the symmetrical position of excircle respectively, the hole of installation percentage table and the M5 screw of installation interchangeable gauge head are in on same the straight line and center through measuring ring to form the both sides head of symmetry, measuring ring's ring diameter size decides according to the size of wanting the interior annular diameter of part of measurement to the interior hole size that makes the ring must enable part intracardiac flexible mistake in, on measuring ring's the excircle M5 of hole and the installation interchangeable gauge head of installation percentage table for the screw boring machine processing form, it has characteristics such as low in manufacturing cost, detection precision height, convenience simple to use, easy popularization.

Description

A kind of special measurement cubing of inner ring groove of part diameter
Technical field
The utility model relates to a kind of special measurement cubing of inner ring groove of part diameter, belong to mechanical metal processing and survey Amount technical field.
Background technology
In metal parts cutting process, some sizes being frequently encountered by part are difficult to measure, the size essence of part The problems such as degree cannot ensure.
Fig. 1 show a certain part, a diameter of B of inner groove of this part, and dimensional accuracy grade is 6 grades, in part manufacture During, when measuring inner groove diameter B, because Central of the parts has an inner circle, center inner circle and dial bore gage during measurement Measurement bar interferes, and dial bore gage cannot be placed, and therefore cannot measure the diameter B of inner groove with conventional dial bore gage. In the past operator measured such part is to be measured with clamp, and because of no scale numerical value on clamp, accuracy of measurement relies primarily on The feel of people and the experience of operator, very big with anthropic factor relation, only veteran operator just has the ability to measure, and one As the dimensional values measured with the method for operator can error very big.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art exists, and provides a kind of low cost of manufacture, detection High precision, easy to use, easy to spread, can guarantee that the special measurement inspection of the inner ring groove of part diameter of part workmanship Tool.
The purpose of this utility model to complete by following technical solution, a kind of special survey of inner ring groove of part diameter Amount cubing, it includes a circular measurement ring, the cylindrical symmetrical position of described measurement ring is separately installed with internal diameter percentage Table and test probe replaceable, the hole installing dial gauge and the M5 screw installing test probe replaceable are on the same line and pass through measurement The center of ring, and form symmetrical both sides head.
As preferred:The circle diameter size of described measurement ring is to be determined according to the size that will measure inner ring groove of part diameter Fixed, and make the endoporus size of annulus must be such that the center inner circle of part is passed through;The cylindrical upper installation dial gauge of described measurement ring Hole and install test probe replaceable M5 screw Boring machine processing form.
This utility model is measured with this cubing, can guarantee that the certainty of measurement of part reaches 0.01mm;Can if changed Change gauge head, just can measure more sizes;It is high, easy to use, easy to spread etc. that it has low cost of manufacture, accuracy of detection Feature, is especially suitable for general mechanical processing industry and uses.
Brief description
Fig. 1 is a kind of existing design of part schematic diagram with inner groove diameter.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the top view of Fig. 2.
Fig. 4 is the left view of Fig. 2.
Specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in detail:Shown in Fig. 2-4, one kind described in the utility model The special measurement cubing of inner ring groove of part diameter, it includes a circular measurement ring 2, described measurement ring 2 cylindrical symmetrical Dial bore gage 1 and test probe replaceable 3 are separately installed with position, the hole of dial gauge 1 and the M5 screw installing test probe replaceable 3 are installed Center that is on the same line and passing through measurement ring 2, and form symmetrical both sides head.
Shown in figure, the circle diameter size of described measurement ring 2 be according to measure the size of inner ring groove of part diameter Lai Determine, and make the endoporus size of annulus must be such that the center inner circle of part is passed through;The cylindrical upper installation percentage of described measurement ring 2 The M5 screw Boring machine processing of the hole of table 1 and installation test probe replaceable 3 forms.
Measuring method of the present utility model is:
a)Before measurement part, according to the size of inner ring groove of part diameter, first adjust the size of outside micrometer, with external diameter thousand Divide distance between two gauge heads on chi calibration measurement ring, to table to " 0 " position;
b)After the size adjusting of measurement ring two gauge head is good, lightly it is inserted in the annular groove of part with handling measurement ring, left and right Rotation measuring ring, the value of reading maximum point and smallest point is exactly the actual size of this inner groove.
Embodiment:Design specialized cubing, cubing is made circular, and the diameter of annulus is according to inner ring groove of part to be measured Determining, the endoporus size of annulus must be such that the center inner circle of part is passed through to the size of diameter;Measurement ring cylindrical on point Not An Zhuan dial bore gage and test probe replaceable, M5 screw requirement Boring machine processing at the hole of dial gauge and gauge head is installed it is ensured that Holes point-blank and by the center of measurement ring, specifically as in Figure 2-4.
Before measurement part, according to accessory size B, first adjust the size of outside micrometer, use outside micrometer calibration measurement Distance between two gauge heads on ring, to table to " 0 " position;After the size adjusting of measurement ring two gauge head is good, with handling cubing lightly It is inserted in annular groove, left-right rotation cubing, the value of reading maximum point and smallest point is exactly the actual size of this inner groove.
