placing the drift diameter gauge in the inner cavity of the workpiece 1, wherein the measuring blade 5 is in contact with the spherical-table-shaped inner cavity 2, and if gaps exist between the abutting blades 6 on the two sides of the drift diameter gauge and the surface of the workpiece 1, the longitudinal section of the inner cavity of the workpiece 1 is over-small; if the abutting edges 6 on the two sides of the go gauge are in contact with the surface of the workpiece 1, rotating the go gauge in the inner cavity of the workpiece 1, and measuring other longitudinal section sizes of the inner cavity of the workpiece 1;
the go gauge and the no-go gauge are rotated for many times, if the two side abutting edges 6 of the go gauge are always in surface contact with the workpiece 1, and the two side abutting edges 6 of the no-go gauge are always in clearance with the surface of the workpiece 1, the workpiece 1 meets the requirement, otherwise, the workpiece 1 does not meet the requirement.
In the process of rotating the go gauge or the no-go gauge, the longitudinal section position of the inner cavity of the workpiece 1, which is not in line with the size requirement, can be marked and counted on the surface of the workpiece 1, and the longitudinal section position is fed back to a production line, so that the production quality is improved.
It should be noted that, the position of the go gauge or the no-go gauge in the inner cavity of the workpiece 1 may be adjusted, the go gauge or the no-go gauge may be rotated in the inner cavity, or the go gauge or the no-go gauge may be taken out from the inner cavity and then the position of the go gauge or the no-go gauge may be adjusted to be placed in the inner cavity again.
The problem of easy tipping of a single test device body is solved, and the invention also provides a method for measuring by using a double test device, which comprises the following steps:
combining a no-go gauge with a first clamping groove 7 and a no-go gauge with a second clamping groove 8 to form a cross-shaped testing tool 9;
placing the cross-shaped inspection tool 9 in the inner cavity of the workpiece 1, and when the four abutting edges 6 of the cross-shaped inspection tool 9 are always in contact with the surface of the workpiece 1, indicating that the inner cavity of the workpiece 1 is overlarge in size;
when the measuring blade 5 of one of the stop gauges of the cross-shaped testing tool 9 abuts against the table-type inner cavity 2, the abutting blades 6 on two sides of the cross-shaped testing tool have gaps with the surface of the workpiece 1, and the measuring blade 5 of the other stop gauge has a gap with the spherical-type inner cavity, the longitudinal section of the inner cavity of the workpiece 1 corresponding to the other stop gauge is too large, specifically, when the situation occurs, the other stop gauge can be seen to shake by taking the former stop gauge as an axis, the stop gauge can pass at the position, namely the size of the longitudinal section does not meet the requirement;
when the measuring edges 5 of the two no-go gauges of the cross-shaped testing tool 9 are abutted against the spherical-table-shaped inner cavity 2 and gaps exist between the abutting edges 6 and the surface of the workpiece 1, the clearance sizes between the four abutting edges 6 and the surface of the workpiece 1 are measured by using the feeler gauge piece, when the four clearance sizes are in the required range, the two longitudinal sections of the inner cavity of the workpiece 1 meet the requirements, otherwise, the inner cavity of the workpiece 1 does not meet the requirements;
before the feeler gauge is used, the cross-shaped check tool 9 is adjusted so that the distances from the four contact blades 6 of the cross-shaped check tool 9 to the surface of the workpiece 1 are close.
The principle that whether the inner cavity meets the size requirement or not is judged by measuring the gap sizes of the four abutting edges 6 and the surface of the workpiece 1 through the feeler gauge piece, when the inner cavity is too small, namely a single gauge cannot pass through, the distance between the abutting edges 6 and the surface of the workpiece 1 is farther, the range value of the distance between the abutting edges 6 and the surface of the workpiece 1 is determined, and when the distance between the abutting edges 6 and the surface of the workpiece 1 exceeds the range value, the size of the inner cavity of the workpiece 1 is too small.
The maximum value exceeding the range value represents that a single gauge cannot pass through the longitudinal section of the interior of the workpiece 1. The range value is determined by the following method: and manufacturing a standard workpiece 1 with the same size as the go gauge, placing the no-go gauge in the inner cavity of the workpiece 1, and accurately measuring the distance between the abutting edges 6 at the two ends of the no-go gauge and the surface of the workpiece 1, wherein the distance is the maximum value of the range value.
The feeler gauge piece which is the same as the maximum value of the range value is selected, if the feeler gauge piece can not be plugged into the gaps between the four abutting edges 6 and the surface of the workpiece 1, the size of the inner cavity of the workpiece 1 meets the requirement, and if the feeler gauge piece can be plugged into the gaps between the four abutting edges 6 and the surface of the workpiece 1, the size of the inner cavity of the workpiece 1 is too small and does not meet the requirement.
When the feeler gauge blade can be inserted into the gap between the four abutting edges 6 and the surface of the workpiece 1, if the measuring edge 5 of one of the compasses is not tightly attached to the inner cavity, the longitudinal section corresponding to the other compasses is too small.
And rotating the cross-shaped inspection tool 9 for multiple times to measure other longitudinal section sizes of the inner cavity of the workpiece 1.
In the invention, the cross-shaped inspection tool 9 is not manufactured by the inspection tool body of two go gauges to measure the size of the inner cavity of the workpiece 1 independently, but the cross-shaped inspection tool 9 manufactured by the two go gauges and the cross-shaped inspection tool 9 manufactured by the two no-go gauges can be matched for use, and at the moment, a feeler gauge piece is not needed. Obviously, the operation method using only one cross-shaped test tool 9 is simpler than the operation method using two cross-shaped test tools 9, and can be selected according to actual conditions.
It should be noted that the single testing tool mentioned in the present invention means that only one testing tool body is used in one measurement, such as a go gauge or a no-go gauge, and the double testing tool mentioned in the present invention means that two testing tool bodies are used in one measurement, and the two testing tool bodies form a cross-shaped testing tool 9.
