According to the further technical scheme, a fixing screw perpendicular to the mounting hole is arranged on the fixing block, and the fixing screw is screwed on the fixing block and can extend into the mounting hole.
An aperture measuring height gauge adopts an aperture detection jig.
An aperture measuring method comprises the following steps of using a height gauge, wherein a probe of a vertical method is arranged on the height gauge, and the probe of the height gauge moves up and down to measure the aperture:
s1, placing the probe into the mounting hole, and fixing the fixing block and the probe by using a fixing screw;
s2, placing the workpiece to be measured on the measuring table, enabling the measuring hole in the workpiece to be vertically arranged, enabling the lowest zero point of the measuring block to be in contact with the upper end face of the workpiece, and setting the reading of the height gauge to be 0 at the moment.
And S3, taking the center of the measuring hole of the workpiece and the measuring block as the same axis, moving the measuring block downwards to form a contact point when the cone is contacted with the measuring hole, stopping moving, and reading the distance b of the downward movement.
And S4, calculating the actual result data of the diameter a of the measuring hole according to the distance b, and judging whether the diameter a is qualified or not.
In a further technical scheme, in the step S1, the probe, the fixed block and the measuring block are arranged on the same axis.
In a further technical solution, in the step S3, the data b of the measurement block moving downward from 0 is less than or equal to the depth of the measurement hole.
In a further aspect, the steps S1 and S2 are limited to use in measuring the first workpiece.

Drawings
FIG. 1 is a block diagram of the present invention;
fig. 2 is a schematic view of the measurement principle of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1 ~ 2, a novel aperture detection jig, includes measuring block 1 and fixed block 2 of integrative structure, measuring block 1 is the same axle center with fixed block 2, measuring block 1 is cone 11, and its below is zero point 12, be equipped with on fixed block 2 with the mounting hole 21 of measuring block 1 same axle center.
According to a further technical scheme, a fixing screw 22 perpendicular to the mounting hole 21 is arranged on the fixing block 2, and the fixing screw 22 is screwed on the fixing block 2 and can extend into the mounting hole 21.
An aperture measuring height gauge adopts an aperture detection jig.
An aperture measuring method comprises the following steps of using a height gauge, wherein a probe of a vertical method is arranged on the height gauge, and the probe of the height gauge moves up and down to measure the aperture:
s1, placing the probe into the mounting hole 21, and fixing the fixed block 2 and the probe by using the fixing screw 22;
and S2, placing the workpiece 3 to be measured on the measuring table, vertically arranging the measuring hole 31 on the workpiece 3, and contacting the lowest zero point 12 of the measuring block 1 with the upper end face of the workpiece 3, wherein the reading of the height gauge is set to be 0.
S3, the center of the measuring hole 31 of the workpiece 3 is made to be coaxial with the measuring block 1, the measuring block 1 is moved downward so that the cone 11 contacts the measuring hole 31 to form a contact point 13, and the movement is stopped to read the distance b of the downward movement.
And S4, calculating the actual data of the diameter a of the measuring hole 31 according to the distance b, and judging whether the diameter a is qualified or not. When the data of b is read, the axis of the measuring block 1 and the contact point 13 form a first right-angle side a1, b forms a second right-angle side, the edge of the cone 11 forms a hypotenuse 14, so that a right-angle triangle is formed, the data of a1 can be calculated according to a trigonometric function, the diameter of the measuring hole 31 is a =2a1, so that the data of the diameter a of the measuring hole 31 can be calculated, when the measuring hole 31 is actually measured, the measuring hole is qualified within a certain range, such as a +/-0.1 mm, and the data range on the height gauge can be obtained through calculation, so that the range of a +/-0.1 mm is reached.
