Abstract

The invention provides a special measuring gage and a measuring method for inner ring groove diameter of a part. The special measuring gage includes an annular measuring ring; an inner diameter dial gauge and an exchangeable probe are respectively arranged on the corresponding symmetrical positions of the outer ring of the measuring ring; the mounting hole of the dial gauge and the M5 screw to mount the exchangeable probe are on the same line and pass through the center of the measuring ring to form two symmetrical probes. The measuring method is performed as follows: a) before measuring the part, adjusting the size of the outer diameter micrometer according to the size of the inner ring groove diameter of the part; calibrating the distance between the two probes on the measuring ring with the outer diameter micrometer and pointing to 0 position; b) after adjusting the size of the two probes on the measuring ring, sleeving the measuring ring gently into the ring groove of the part by hand and turning the measuring ring from left to the right so as to read the values at the maximum point and the minimum point, which indicate the actual size of the inner ring groove. The measuring gage of the invention is cost-effective to manufacture, can achieve high precision, is easy to use and can be widely applied.

Description

The special measurement cubing of a kind of inner ring groove of part diameter and measuring method
Technical field
The present invention relates to special measurement cubing and the measuring method of a kind of inner ring groove of part diameter, belong to mechanical metal in-process measurement technical field.
Background technology
In metal parts cutting process, it is frequently encountered by the problems such as some size of part is difficult to measure, and the dimensional accuracy of part cannot ensure.
Fig. 1 show a certain part, the a diameter of B of inner groove of this part, dimensional accuracy grade is 6 grades, in part manufacture process, when measuring inner groove diameter B, owing to Central of the parts has an inner circle, during measurement, center inner circle interferes with the measurement bar of dial bore gage, dial bore gage cannot be placed, and therefore cannot measure the diameter B of inner groove with conventional dial bore gage.Operator measured this type of part in the past is to measure with clamp, because of on clamp without scale numerical value, accuracy of measurement relies primarily on the feel of people and the experience of operator, the biggest with anthropic factor relation, the most veteran operator just has the ability to measure, and the dimensional values meeting error that general operator measures by the method is the biggest.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and provide a kind of low cost of manufacture, accuracy of detection high, easy to use, easy to spread, can guarantee that special measurement cubing and the measuring method of the inner ring groove of part diameter of part workmanship.
It is an object of the invention to complete by following technical solution, a kind of special measurement cubing of inner ring groove of part diameter, it includes a circular measurement ring, it is separately installed with dial bore gage and test probe replaceable on the symmetrical position of cylindrical of described measurement ring, the hole installing dial gauge and the M5 screw installing test probe replaceable are on same straight line and by the center of measurement ring, and form the both sides head of symmetry.
As preferably: the circle diameter size of described measurement ring is that the size according to inner ring groove of part diameter to be measured determines, and the center inner circle of part is passed through to make the interior hole size of annulus must be such that;The hole installing dial gauge on the cylindrical of described measurement ring and the M5 screw Boring machine processing installing test probe replaceable form.
A kind of measuring method utilizing described special measurement cubing to carry out inner ring groove of part diameter, described measuring method is:
a )Before measuring part, according to the size of inner ring groove of part diameter, first adjust the size of outside micrometer, by the spacing of two gauge heads on outside micrometer calibration measurement ring, to table to " 0 " position;
B) after the size adjusting of measurement ring two gauge head is good, with hands, measurement ring being inserted in the annular groove of part lightly, left-right rotation measurement ring, the value reading maximum point and smallest point is exactly the actual size of this inner groove.
The present invention measures by this cubing, can guarantee that the certainty of measurement of part reaches 0.01mm;If replacing test probe replaceable, just more size can be measured;It has the features such as low cost of manufacture, accuracy of detection are high, easy to use, easy to spread, is especially suitable for general mechanical processing industry and uses.
Accompanying drawing explanation
Fig. 1 is existing a kind of design of part schematic diagram with inner groove diameter.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is the top view of Fig. 2.
Fig. 4 is the left view of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 2-4, the special measurement cubing of a kind of inner ring groove of part diameter of the present invention, it includes a circular measurement ring 2, it is separately installed with dial bore gage 1 and test probe replaceable 3 on the symmetrical position of cylindrical of described measurement ring 2, the hole installing dial gauge 1 and the M5 screw installing test probe replaceable 3 are on same straight line and by the center of measurement ring 2, and form the both sides head of symmetry.
Shown in figure, the circle diameter size of described measurement ring 2 is that the size according to inner ring groove of part diameter to be measured determines, and the center inner circle of part is passed through to make the interior hole size of annulus must be such that;The hole installing dial gauge 1 on the cylindrical of described measurement ring 2 and the M5 screw Boring machine processing installing test probe replaceable 3 form.
A kind of measuring method utilizing described special measurement cubing to carry out inner ring groove of part diameter, described measuring method is:
a )Before measuring part, according to the size of inner ring groove of part diameter, first adjust the size of outside micrometer, by the spacing of two gauge heads on outside micrometer calibration measurement ring, to table to " 0 " position;
B) after the size adjusting of measurement ring two gauge head is good, with hands, measurement ring being inserted in the annular groove of part lightly, left-right rotation measurement ring, the value 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 determines according to the size of inner ring groove of part diameter to be measured, and the interior hole size of annulus must be such that the center inner circle of part is passed through;The cylindrical of measurement ring is respectively mounted dial bore gage and test probe replaceable, the M5 screw requirement Boring machine processing at the hole of dial gauge and gauge head is installed, it is ensured that holes is point-blank and by the center of measurement ring, the most as in Figure 2-4.
Before measuring part, according to accessory size B, first adjust the size of outside micrometer, by the spacing of two gauge heads on outside micrometer calibration measurement ring, to table to " 0 " position;After the size adjusting of measurement ring two gauge head is good, with hands, cubing being inserted in annular groove lightly, left-right rotation cubing, the value reading maximum point and smallest point is exactly the actual size of this inner groove.
