Description
Technical field
The utility model relates to machine-building fields of measurement, more particularly to a kind of hole symmetry degree gauge.
Background technique
Existing a kind of automobile fuel pump monoblock pump, as shown in figure 5, the diameter d1 of cylinder inclined hole to be detected is ￠ 5+ on the pump housing
0.05 0mm, the diameter d in relative datum hole are that 20 mm of ￠ has symmetrical requirement, and its symmetry is 0.05 mm, existing inspection
The defects of method of scribing line is usually used in survey method, and it is low that there are detection efficiencies, and error is big.
Summary of the invention
There is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art it is a kind of have it is quick and easy determine to
The symmetry in detection hole relative datum hole whether He Ge hole symmetry degree gauge.
The technical solution of the utility model is: a kind of hole symmetry degree gauge comprising standard column and measurement column, standard column are straight
Diameter matches with bore dia d1 to be detected, is inserted into gaging hole to be checked, and measurement column diameter is that benchmark bore dia d subtracts gaging hole to be checked
The half of diameter d1 difference, the size for the gap that examination criteria column periphery and datum hole inner wall are formed.
The further technical solution of the utility model is: described standard column one end is equipped with handle.
The further technical solution of the utility model is: the standard column is equipped with chamfering far from one end of handle.
The further technical solution of the utility model is: the handle is equipped with anti-skid chequer.
The further technical solution of the utility model is: described measurement column one end is equipped with measurement handle.
The further technical solution of the utility model is: the measurement column is equipped with measurement far from one end of measurement handle and falls
Angle.
The further technical solution of the utility model is: the measurement handle periphery is equipped with skid resistance strip.
There is the utility model the quick and easy symmetry for determining gaging hole relative datum to be checked hole to be compared with prior art
Can no qualification, i.e. measurement column be inserted into datum hole from the two sides of standard column determines, it is just qualified that two sides can be inserted into, remaining is
It is unqualified.
It is further described below in conjunction with detailed construction of the drawings and specific embodiments to the utility model.

Specific embodiment
Embodiment 1
The symmetry for measuring gaging hole relative datum to be checked hole on monoblock pump as shown in Figure 5, can be used the present invention, picture 1-4
It is shown, a kind of hole symmetry degree gauge comprising standard column 1 and measurement column 2,1 diameter of standard column and gaging hole to be checked (can make straight
Hole is also possible to inclined hole, similarly hereinafter) diameter d1 matches, and 1 diameter of the present embodiment Plays column is ￠ 5+0.05 0mm, for convenience
Standard column 1 is inserted into gaging hole to be checked, is equipped with handle 11 in one end of standard column 1, handle 11 is equipped with anti-skid chequer 111, standard column 1
The other end is equipped with chamfering 12.In this way, being equipped with handle 11 convenient for taking standard column 1, have chamfering 12 be easy to allow the insertion of standard column 1 to
In detection hole.
The diameter of measurement column 2 is the half that benchmark bore dia d subtracts bore dia d1 difference to be detected, its diameter in the present embodiment
Are as follows: 2=7.5 mm of (20-5) ÷.For the ease of detection, 2 one end of measurement column is equipped with measurement handle 21, and measurement 21 periphery of handle is equipped with
Skid resistance strip 211,2 other end of measurement column are equipped with measurement chamfering 22.In this way, be equipped with measurement handle 21 convenient for take measurement column 2 into
Row detection has measurement chamfering 12 to be easy to that measurement column 2 is allowed to be inserted into the gap that 1 periphery of standard column is formed with datum hole inner wall.
Application method of the invention is as follows: measuring 20 mm of inclined hole ￠ 5+0.05 0mm relative datum hole ￠ on monoblock pump
It is symmetrical when, by standard column 1 be inserted into monoblock pump on ￠ 5+0.05 0mm inclined hole in, then by measurement column 2 be inserted into 1 periphery of standard column
In the one of gap formed with datum hole inner wall, as shown in Figure 3.If cannot be inserted into gap, the product is just determined
Symmetry it is unqualified；If can be inserted into gap, measurement column 2 is just inserted into 1 periphery of standard column again and is formed with datum hole inner wall
Another gap in, as shown in Figure 4.If cannot be inserted into gap, just determine that the symmetry of the product is unqualified；If energy
It is inserted into gap, just determines that the symmetry of the product is qualified, in this way, the symmetry of detection inclined hole is very convenient and quick.
Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can also be with other
Mode realizes that any obvious replacement is in the protection of the utility model under the premise of not departing from the technical program design
Within the scope of.
