[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] See Figures 2 - 6, An embodiment of an automatic machine energy adjustment test tool for firearm research and development, comprising a regulator body 1, an air vent adjusting rod 2 (including an air vent adjusting screw rod), a volume adjusting rod 3 (including a volume adjusting screw rod), an air vent adjusting rod locking nut 4, and a volume adjusting rod locking nut 5. The air vent adjusting rod 2 is installed in the threaded hole of the regulator body 1. By rotating the air vent adjusting rod, it moves along the axis under the action of thread fitting; the volume adjusting rod 3 is installed in the threaded hole of the air vent adjusting rod 2. By rotating the volume adjusting rod, it moves along the axis under the action of thread fitting; the air vent adjusting locking nut 4 is installed on the air vent adjusting rod 2 for locking the air vent adjusting rod 2 and the regulator body 1; the volume adjusting locking nut 5 is installed on the volume adjusting rod 3 for locking the volume adjusting rod 3 and the air vent adjusting rod 2.

[0034] Working process:

[0035] According to the size of the air vent area and the initial gas volume given by theoretical calculation, query the corresponding numerical values on the scale of the automatic machine energy adjustment test tool in the parameter query table, and adjust the automatic machine energy adjustment test tool to the corresponding numerical values; install the adjusted automatic machine energy adjustment test tool on the firearm for corresponding tests and experiments. During the experiment, when it is necessary to adjust the size of the air vent area and the initial gas volume, the following steps can be taken: loosen the air vent adjusting rod nut, rotate the air vent adjusting rod, lock the air vent adjusting rod nut, and check the scale of the air vent adjusting rod; loosen the volume adjusting rod nut, rotate the volume adjusting rod, lock the volume adjusting rod nut, and check the scale of the volume adjusting rod; according to the numerical values of each scale, look up the table to determine the corresponding size of the air vent cross-section and the initial gas volume. Since the scale is in the form of engraved lines, it cannot achieve stepless adjustment in the strict sense. When more accurate sizes of the air vent cross-section and the initial gas volume are required, they can be accurately obtained on the digital model of the adjustment tool by measuring relevant dimensions. If re-adjustment is needed, it can be repeated according to the above method.

[0036] The format of the parameter query table is:
