[0002] Pressure gauges are instruments that use elastic elements as sensitive elements to measure and indicate pressures higher than the ambient pressure. They are widely used in almost all industrial processes and scientific research fields. They can be found everywhere in the fields of thermal pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of their elastic sensitive elements with high mechanical strength and easy production.

[0003] With the iteration of technology, the calibration operation of pressure gauges has developed from manual calibration to automatic calibration. Currently, there are many types of automatic calibration equipment, which integrate pressure controllers, gas generators, intelligent recognition systems, etc., and can achieve good automated calibration operations.

[0004] However, since pressure gauges have two types, axial and radial, the current automatic calibration platform equipment cannot automatically install axial pressure gauges and radial pressure gauges at the same time, and can only perform calibration inspection on one type of pressure gauge, which greatly affects the efficiency of batch calibration of the automatic calibration platform.

[0027] Please refer to Figure 3 , Figure 4 , Fig.10 and Fig.11, and also includes multiple first limit members 18 and multiple second limit members 20.

At this time, the entire sleeve joint 22 and the hard conduit 24 move downward, so that the sleeve joint 22 can be separated from the docking joint 27.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4 , also includes a first motor 31, a support shaft 32, a sliding box 33, a second motor 34 and a third motor 35.

[0033] Please refer to Figure 1 and Figure 2 , and also includes multiple groups of conveyor belts 37, which are connected to the frame 1 and are used to respectively export the pressure gauges to be tested.

[0034] In the above embodiment, multiple groups of conveyor belts 37 export the calibrated pressure gauges.

[0035] It should be noted that: this platform also has the necessary power system and control processing terminal, the camera recognition terminal 10 is electrically connected to the control processing terminal, the control processing terminal receives and analyzes the information of the camera recognition terminal 10, and controls the device to perform pressurization calibration operations, which are clear existing technologies and will not be elaborated on.

[0036] Working principle: The external conveyor belt 37 cooperates with the guide rail 5 and the guide groove 7 to convey the parts. The radial pressure gauges 2 in batches are conveyed to the guide rail 5 by the external conveyor belt 37 and arranged in sequence. The first limiter 18 cooperates with the first torsion spring 19 to prevent the radial pressure gauges 2 from falling from the end of the guide rail 5. The axial pressure gauges 3 in batches are conveyed to the guide groove 7 and arranged in sequence. The second limiter 20 cooperates with the second torsion spring 21 to prevent the axial pressure gauges 3 from falling from the end of the guide groove 7. The pressure gauges to be tested in batches can also be placed on the guide rail 5 and the guide groove 7 manually. When the axial pressure gauge 3 or the radial pressure gauge 2 is selected for calibration, the third motor 35 drives the gear rack assembly 36 to move, thereby driving the sliding box 33, the support shaft 32, the second motor 34, the rotating frame 4, the guide rail 5 and the guide groove 7 away from the clamping mechanism 8. After the retreat movement is completed, the rotation of the guide rail 5 and the guide groove 7 is not interfered with. The second motor 34 drives the support shaft 32 to rotate 180 degrees, and the support shaft 32 drives the rotating frame 4, the guide rail 5 and the guide groove 7 to rotate, so as to select the axial type or radial type pressure gauge. After that, the third motor 35 operates to make the rotating frame 4, the guide rail 5 and the guide groove 7 move forward and wait for the clamping operation. The first motor 31 is operated to drive the rotating shaft 81 to rotate, and the rotating arm 83 moves in the stepped slide 14. The rotating arm 83 pushes the inclined guide slide 17 on the second spring rod 16 to compress the second spring rod 16. At this time, the rotating arm 83 is subjected to an upward force. When the rotating arm 83 rotates to one side of the adjustment frame 4 and each clamping fixture 84 is aligned with the docking joints 27 on the first row of pressure gauges to be tested, the first motor 31 stops running. Due to the force of the second spring rod 16, the rotating arm 83 can cross the step of the slide 14 and move to the upper side of the slide 14. The spline sleeve 82 moves upward along the axial direction of the rotating shaft 81. At this time, the docking joint 27 enters the inner side of the clamping fixture 84, operates the first electric push rod 86, and the pull rod 85 drives the clamping fixture 84, so that the clamping fixture 84 stably clamps the first row of pressure gauges to be tested, and then the third motor 35 operates to repeat the retreat operation. After the first limiter 18 or the second limiter 20 rotates and abuts against the pressure gauge to be tested, the first torsion spring 19 or the second torsion spring 21 is compressed until the first pressure gauge to be tested is transferred to the clamping fixture 84, and the subsequent pressure gauges to be tested fill the vacant position. The first limiter 18 and the second limiter 20 are reset to limit due to the elastic force of the first torsion spring 19 or the second torsion spring 21; Then, the second electric push rod 29 is operated to drive the lower pressure piece 30 and the lower pressure plate 28, so that the sliding sleeve on the sleeve joint 22 moves to the lower end, and the sleeve joint 22 is in an engageable state. The first motor 31 continues to operate, driving the rotating shaft 81, the spline sleeve 82 and the rotating arm 83 to rotate. The rotating arm 83 moves on the upper side of the slide groove 14, and then the rotating arm 83 abuts against the inclined guide slide bar 17 on the first spring rod 15, pushing the guide slide bar 17 at this position to compress the first spring rod 15. At this time, the rotating arm 83 is subjected to a downward force. When the rotating arm 83 moves to one side of the sleeve joint 22, each docking joint 27 is aligned with the sleeve joint 22. Due to the force of the first spring rod 15, the rotating arm 83 moves to the lower side of the slide groove 14. The downward movement of the rotating arm 83 During the process, the clamping tool 84 and the pressure gauge to be tested are driven to move downward, so that the docking joint 27 on the pressure gauge to be tested is inserted into the sleeve joint 22 to achieve engagement, and the second electric push rod 29 moves, so that the lower pressure plate 28 and the sliding sleeve move up and return to their original positions, so as to achieve stable engagement between the sleeve joint 22 and the docking joint 27. Then, the existing pressurization calibration technology is used to inflate and pressurize the hose 25 and the hard conduit 24 for calibration. After the calibration is completed, the second electric push rod 29 is operated to move the sleeve joint 22 and the hard conduit 24 downward, and the reset spring 26 is compressed, so that the sleeve joint 22 and the docking joint 27 can be separated. The first motor 31 is driven to drive the calibrated pressure gauge to the position of the conveyor belt 37, and the clamping tool 84 is released for collection. The above operation is repeated to perform the automated calibration inspection operation.
