Detailed Description
The first embodiment is as follows:
the utility model provides a cone periphery sealing surface detection tool, as shown in figures 1 to 5, comprising a go gauge 1 and a no-go gauge 2, wherein the height from a sealing line of a periphery sealing surface of a cone 3 to be detected to the bottom surface of the cone 3 to be detected is H, the go gauge 1 comprises a first detection ring 10 and first supporting feet 11, the inner ring of the first detection ring 10 is provided with a first datum line 12 matched with the shape of the sealing line of the periphery sealing surface of the cone 3 to be detected, the first supporting feet 11 are four distributed on the first detection ring 10, the distance from the bottom end of all the first supporting feet 11 to the first datum line 12 is H, the no-go gauge 2 comprises a second detection ring 20 and second supporting feet 21, the inner ring of the second detection ring 20 is provided with a second datum line 22 matched with the shape of the periphery sealing surface of the cone 3 to be detected, the second supporting feet 21 are four distributed on the second detection ring 20, the distances from the bottom ends of all the second supporting feet 21 to the second datum line 22 are H, the profile of the first reference line 12 is larger than the design profile of the sealing line of the peripheral sealing surface of the cone 3 to be measured and has a first tolerance therebetween, and the profile of the second reference line 22 is smaller than the design profile of the sealing line of the peripheral sealing surface of the cone 3 to be measured and has a second tolerance therebetween.
In the detection process, the go gauge 1 can be used for measuring the sealing line of the peripheral sealing surface of the cone 3 to be detected, the cone 3 to be detected is placed on the measuring platform 4, the go gauge 1 is sleeved on the cone to be detected, and in view of the fact that the height from the sealing line of the peripheral sealing surface of the cone 3 to be detected to the bottom surface of the cone 3 to be detected is H, the distance from the bottom end of each first supporting leg 11 to the first reference line 12 is H, and therefore the first reference line 12 can be matched with the sealing line of the peripheral sealing surface of the cone 3 to be detected. Because the contour of the first reference line 12 is greater than the design contour of the sealing line of the peripheral sealing surface of the cone 3 to be measured and a first tolerance exists between the first reference line 12 and the sealing line of the peripheral sealing surface of the cone 3 to be measured, which is equivalent to that a clearance fit is formed between the first reference line 12 and the sealing line of the peripheral sealing surface of the cone 3 to be measured, as shown in fig. 4, the bottom ends of all the first supporting feet 11 fall on the measuring platform 4 to be contacted with the measuring platform 4, which indicates that the machining precision of the sealing line of the peripheral sealing surface of the cone 3 to be measured meets the requirement of the general rule 1, and if at least one bottom end of the first supporting foot 11 does not fall on the measuring platform 4, i.e., a clearance exists between the bottom end of the first supporting foot 11 and the measuring platform 4, which indicates that the machining precision of the sealing line of the peripheral sealing surface of the cone 3 to be measured does not meet the requirement of the general rule 1, and the detection of the general rule 1 is ended. Then the no-go gauge 2 is used for measuring the sealing line, the no-go gauge 2 is sleeved on the cone 3 to be measured, because the distances from the bottom ends of all the second supporting legs 21 to the second reference line 22 are all H, meanwhile, the profile of the second reference line 22 is smaller than the design profile of the sealing line of the peripheral sealing surface of the cone 3 to be measured, and a second tolerance exists between the two, which is equivalent to that the interference fit is formed between the second reference line 22 and the sealing line of the peripheral sealing surface of the cone 3 to be measured, the second reference line 22 is supported by the sealing line, as shown in FIG. 5, if the bottom end of one second supporting leg 21 does not fall on the measuring platform 4, namely a gap is formed between the bottom end of the second supporting leg 21 and the measuring platform 4, the processing precision of the sealing line of the peripheral sealing surface of the cone 3 to be measured meets the requirement of the no-go gauge 2, if the bottom ends of all the second supporting legs 21 fall on the measuring platform 4 to be contacted with the measuring platform 4, and indicating that the machining precision of the sealing line of the peripheral sealing surface of the cone 3 to be detected does not meet the requirement of the no-go gauge 2, and ending the detection of the no-go gauge 2. It can be seen that the whole detection process is convenient and fast, whether the machining precision of the sealing line of the peripheral sealing surface of the cone 3 to be detected meets the requirement or not can be directly judged in the detection process, and the detection efficiency is greatly improved, for example, the detection device is particularly suitable for window glass on a machine door of a drum washing machine. The design outline of the sealing line of the peripheral sealing surface of the cone to be detected is determined by a design drawing of the sealing line of the peripheral sealing surface of the cone to be detected, and the actual outline is opposite to the actual outline, and the actual outline is required to be detected.
The first tolerance is the size difference range from the first reference line 12 of the first detection ring 10 to the sealing line of the outer peripheral sealing surface of the cone 3 to be detected, and the second tolerance is the size difference range from the second reference line 22 of the second detection ring 20 to the sealing line of the outer peripheral sealing surface of the cone 3 to be detected.

For another example, the cone 3 to be measured is a pyramid, and the sealing line of the outer peripheral sealing surface of the cone 3 to be measured, the first reference line 12, and the second reference line 22 are all polygons. The pyramid may be a regular pyramid, such as a square pyramid, or may be another pyramid with a non-equilateral base.

Alternatively, as shown in fig. 7, the first supporting leg 11 may be designed to have a telescopic structure such that the bottom end of the first supporting leg 11 can be adjusted in height with respect to the first reference line 12.
For the same reason, the second supporting leg 21 can be fixed on the second detecting ring 20 to ensure the accuracy of long-term use, and in order to make the no-go gauge 2 suitable for cone parts with different sizes, the second supporting leg 21 can also be movably connected to the second detecting ring 20 to make the bottom end of the second supporting leg 21 adjust the height relative to the second datum line 22, for example, the first supporting leg 11 is connected with the first detecting ring 10 through a thread, and the height from the bottom end of the first supporting leg 11 to the first datum line 12 can be adjusted by rotating the first supporting leg 11
Still alternatively, the second supporting foot 21 may be designed to be a telescopic structure, so that the bottom end of the second supporting foot 21 can be adjusted in height relative to the second reference line 22.
