[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 As shown: a pressure instrument calibration machine, including a machine body 1, a placing table 111 is fixedly installed on one side of the machine body 1, and is used to place the pressure gauge to be tested. A first test table 2 and a second test table 3 are respectively arranged on the workbench of the machine body 1, and a plurality of quick-connect bases 6 are fixedly installed on both test tables. The quick-connect base 6 includes a quick-connect base shell 68, and electric telescopic rods 1 61 are fixedly installed on both sides of the quick-connect base shell 68. A connecting plate 65 is fixedly installed on the top of each electric telescopic rod 1 61, and a connecting block 66 is fixedly installed on one side of the connecting plate 65. An electric telescopic rod 2 62 is fixedly installed on the top of the connecting block 66, and a spring 64 is sleeved inside the output rod of the electric telescopic rod 2 62. A T-shaped block 63 is fixed on one end of the output rod of the electric telescopic rod 2 62, and the bottom of the T-shaped block 63 is slidably connected to the other side of the connecting plate 65. The specific connection method is that a track 67 is fixed on one side of the connecting plate 65, and a sliding groove corresponding to the track 67 is opened at the bottom of the T-shaped block 63.

[0023] When installing the pressure gauge 7 to be tested, the interface end of the pressure gauge 7 to be tested is directly pressed into the quick-connect base 6. When the bolt of the pressure gauge 7 to be tested squeezes the T-block 63, the T-block 63 contracts outwardly under the action of the spring 64. When the bolt of the pressure gauge 7 to be tested is completely pressed to the bottom of the T-block 63, the T-block 63 rebounds a part and firmly clamps the bolt. Then the electric telescopic rod 1 61 contracts downward, so that the interface end of the pressure gauge 7 to be tested can be firmly engaged with the interface end of the branch pipe 9 in the quick-connect base 6. When the pressure gauge 7 to be tested needs to be removed, the electric telescopic rod 2 62 is controlled to drive the T-block 63 to contract outward, so that the pressure gauge 7 to be tested can be easily removed.

[0024] A pressure gauge 7 to be tested can be installed on each quick-connect base 6, so that the entire device can complete the testing of multiple pressure gauges at the same time. A camera 5 is fixedly installed on the side plate of one side of the quick-connect base 6 at the position corresponding to the quick-connect base 6. The camera 5 is used to record the changes in the pressure value on the pressure gauge 7 to be tested in front, and output the recorded value to the PLC controller. A display 4 is installed on the top of the body 1 through a bracket. The display can convert the signal to be displayed on the PLC controller into a graphic form for the operator to observe.

[0025] In order to facilitate the operator to find the problematic pressure gauge 7 to be tested, a plurality of warning lights 8 are installed on the first test platform 2 and the second test platform 3. Each warning light 8 corresponds to a quick-connect base 6. When the PLC controller detects a problematic pressure gauge 7 to be tested, the corresponding warning light 8 will flash to give a warning.

[0026] The bottoms of the multiple quick-connect bases 6 on the first inspection table 2 and the second inspection table 3 are all connected to branch pipes 9, the tops of the multiple branch pipes 9 are connected to the quick-connect bases 6, and the other ends of the multiple branch pipes 9 are respectively connected to pipe one 100 and pipe two 101, and pipe one 100 and pipe two 101 are connected to each other through pipes, and pipe one 100 and pipe two 101 are also connected to main pipe three 102 through pipes, and the two ends of the main pipe three 102 are respectively connected to an electric booster pump 13 and a pressure regulator 14, and a stop valve two 12 is installed on the main pipe three 102 near one end of the electric booster pump 13. 4. Multiple stop valves one 11 are installed between pipe one 100 and pipe two 101, and the multiple stop valves one 11 cooperate with each other to control the air pressure flowing in each branch pipe 9.

[0027] The electric booster pump 13, the pressure regulator 14, the stop valve 11 and the stop valve 2 12 are all connected to the PLC controller and are regulated by the PLC controller without manual intervention.

[0028] Before calibrating the pressure gauge 7 to be tested and recording the value on the pressure gauge 7 to be tested, it is necessary to gently move the pressure gauge 7 to be tested to stabilize the pointer thereon, and then record it. Therefore, a plurality of electric telescopic rods 3 81 are fixedly installed on the side panels on one side of the first testing platform 2 and the second testing platform 3, and each electric telescopic rod 3 81 corresponds to a quick-connect base 6 respectively. When the electric telescopic rod 3 81 is extended, it lightly taps the pressure gauge 7 to be tested installed on the quick-connect base 6.

[0029] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
