[0028] Figure 1 The present invention is a structural schematic diagram of the push-pull tool measuring tool for air-conditioning compressors, which shows a base plate 1, a tool block 2, a micrometer 3, and a push-pull tool 4 for chamfering an air-conditioning compressor cylinder.

The measuring rod of the micrometer 3 is perpendicular to the bottom plate 1, and the measuring head of the micrometer 3 contacts the chamfered upper surface of the chamfering push-pull tool 4 for the air conditioner compressor cylinder.

[0030] Specifically, in this embodiment, the chamfer angle γ of the chamfering push-broach 4 for the air-conditioning compressor cylinder is 26°, and a tooling block 2 with an inclination angle of 26° for the measuring groove is selected. The chamfering push-broach 4 for the air-conditioning compressor cylinder is placed in the measuring groove, and the teeth of the chamfering push-broach 4 for the air-conditioning compressor cylinder are in a horizontal state. The diagonal length of the chamfering push-broach 4 for the air-conditioning compressor cylinder is S, the vertex height of the chamfering push-broach 4 for the air-conditioning compressor cylinder is h1, the vertex height of the other side of the chamfering push-broach 4 for the air-conditioning compressor cylinder is h2, the angle from the diagonal of the chamfering push-broach 4 for the air-conditioning compressor cylinder to the surface of the measuring groove is α, the angle between the surface of the measuring groove and the vertical direction is β, and the height difference between the two vertices of the chamfering push-broach 4 for the air-conditioning compressor cylinder is h0, and the relevant relationship is as follows:

The range of the error value can be set in advance. If the value measured by the micrometer 3 falls within the range, the chamfering push-pull tool 4 for the air-conditioning compressor cylinder is qualified; otherwise, it is unqualified.

[0034] Further, the micrometer 3 is mounted on the base plate 1 through a bracket. The bracket includes a column 5, a fixing block 6 and a cross bar 7.

[0040] Specifically, for the same model of air-conditioning compressor cylinder chamfering push-pull tool 4, a height gauge 8 of the same height can be configured to facilitate zeroing of the micrometer 3.

[0041] Step S102 : placing the air-conditioning compressor cylinder under test in the measuring groove of the tooling block 2 using the chamfering push-pull tool 4 .
