[0002] The pressure gauge generates elastic deformation under the action of pressure through the sensitive elements in the gauge (such as Bourdon tube, diaphragm box, bellows), and this deformation is transmitted to the pointer through the conversion mechanism of the movement in the gauge, causing the pointer to rotate, thereby indicating the measured pressure value on the dial. The pressure gauge calibration platform cooperates with the pressure standard to complete the inspection and calibration of various pressure instruments. It is widely used in measurement, petroleum, chemical, electric power, national defense and instrument manufacturing industries to ensure that the measurement accuracy of instruments meets national or international standards.

However, the calibrated pressure gauge may be newly produced and needs to be calibrated after being used for a period of time, and there will be some quality problems. The problematic pressure gauge will not be able to withstand the pressure during calibration and will explode, so the fragments produced by the explosion will fly around and cause injuries to personnel, and the scattered fragments are difficult to collect and process.

[0015] A pressure gauge calibration method comprises the following steps:

[0016] S1. First, fix the pressure gauge body by clamping the clamp seat, then start the motor to drive the shaft to rotate, the shaft drives the first wheel to rotate, the first wheel drives the belt to rotate, the belt drives the second wheel to rotate, the second wheel drives the rod to rotate, the rod drives the movable cover to rotate, the movable cover gradually deflects to the fixed cover to close, at this time the movable cover and the fixed cover fully protect the pressure gauge body;

The moving plate drives the camera to adjust the height so that the camera is aligned with the pressure gauge body. Then the first cylinder is activated. The first cylinder pushes the moving block to move so that the camera gradually approaches the pressure gauge body so that the pressure gauge body is completely presented in the camera.

[0018] S3. Use an air pump to pressurize the pressure gauge body for calibration. When a certain value is reached, start the third air cylinder, which drives the push plate to move, and the push plate drives the knocking rod to move. The knocking rod knocks the pressure gauge body through the gasket, and then recognizes it again through the camera. The final recognition result is compared and calculated with the standard pressure value of the high-precision pressure sensor to obtain the indication errors of the pressure instrument;

[0019] S4. If the pressure gauge body has mass and causes explosion during calibration, the movable cover and the fixed cover will shield the exploded fragments, and the second cylinder will be started to drive the connecting plate to move downward, and the connecting plate will drive the supporting plate to move downward, and the supporting plate will drive the clamping seat and the pressure gauge body to move. When the supporting plate and the connecting plate move downward, they will drive the limit rod to slide inside the guide groove, so the clamping seat and the pressure gauge body will move downward stably. When they move to the corner of the guide groove, the limit rod at the bottom will continue to move along the guide groove.

At this time, the support plate is in the maximum tilt state, and the pressure gauge body slides out of the clamping seat by inertia, and finally falls onto the guide plate for collection, and the exploded fragments fall onto the guide plate, and finally slide into the guide plate along the guide plate for collection;

[0020] S5. If the size of the pressure gauge body is slightly larger and it is difficult for the pressure gauge body to fall off when it is tilted, the support plate drives the clamp seat and the pressure gauge body to move downward and eventually it is in a tilted state. When the pressure gauge body is tilted, it gradually contacts the friction pad. The support plate continues to drive the pressure gauge body to move. The pressure gauge body and the friction pad rub against each other, and the force generated by the friction causes the spring to gradually compress. Finally, the pressure gauge body is gradually pulled out of the clamp seat and falls onto the guide plate for collection.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. In the present invention, after the pressure gauge body is clamped and fixed by the clamp seat, the motor is started to drive the rotating shaft to rotate, the rotating shaft drives the first rotating wheel to rotate, the first rotating wheel drives the belt to rotate, the belt drives the second rotating wheel to rotate, the second rotating wheel drives the rotating rod to rotate, the rotating rod drives the movable cover to rotate, and the movable cover gradually deflects until the fixed cover is closed. At this time, the movable cover and the fixed cover fully protect the pressure gauge body to avoid the pressure gauge body from bursting due to its own quality problems under strong pressure, causing fragments to fly and cause injuries to personnel.

[0023] 2. In the present invention, the second cylinder is started to drive the connecting plate to move downward, the connecting plate drives the supporting plate to move downward, the supporting plate drives the clamping seat and the pressure gauge body to move, and when the support plate and the connecting plate move downward, they drive the limit rod to slide inside the guide groove, so that the clamping seat and the pressure gauge body move downward stably. When moving to the corner of the guide groove, the limit rod at the bottom continues to move along the guide groove. At this time, the support plate drives the clamping seat and the pressure gauge body to gradually tilt, and then the top limit rod reaches the corner of the guide groove. At this time, the support plate is in the maximum tilt state, and the pressure gauge body slides out of the clamping seat by inertia, and finally falls onto the guide plate for collection, and the exploded fragments fall on the guide plate, and finally slide into the guide plate along the guide plate for collection.

[0024] 3. In the present invention, if the size of the pressure gauge body is slightly larger and it is difficult for the pressure gauge body to fall off when it is tilted, the support plate drives the clamp seat and the pressure gauge body to move downward, and finally it is in a tilted state. When the pressure gauge body is tilted, it gradually contacts the friction pad, and the support plate continues to drive the pressure gauge body to move. The pressure gauge body and the friction pad rub against each other, and the force generated by the friction causes the spring to be gradually compressed. Finally, the pressure gauge body is gradually pulled out of the clamp seat and falls onto the guide plate for collection, thereby facilitating the rapid unloading of the pressure gauge body.

[0046] In this embodiment, during the calibration, the first gas rod 23 is started according to the height of the pressure gauge body 46. The first gas rod 23 is extended and retracted to drive the movable plate 21 to move. The movable plate 21 drives the camera 22 to adjust the height so that the camera 22 is aligned with the pressure gauge body 46. Then the first cylinder 25 is started. The first cylinder 25 pushes the movable block 24 to move, so that the camera 22 gradually approaches the pressure gauge body 46, so that the pressure gauge body 46 is completely presented in the camera 22.

[0047] Working principle:

[0048] Step 1, first, clamp and fix the pressure gauge body 46 through the clamping seat 45, then start the motor 31 to drive the rotating shaft 32 to rotate, the rotating shaft 32 drives the first rotating wheel 33 to rotate, the first rotating wheel 33 drives the belt 34 to rotate, the belt 34 drives the second rotating wheel 35 to rotate, the second rotating wheel 35 drives the rotating rod 36 to rotate, the rotating rod 36 drives the movable cover 38 to rotate, the movable cover 38 gradually deflects to the fixed cover 39 to close, at this time the movable cover 38 and the fixed cover 39 fully protect the pressure gauge body 46;

[0049] Step 2: During the verification, the first gas rod 23 is activated according to the height of the pressure gauge body 46. The first gas rod 23 is extended and retracted to drive the movable plate 21 to move. The movable plate 21 drives the camera 22 to adjust the height so that the camera 22 is aligned with the pressure gauge body 46. Then, the first cylinder 25 is activated. The first cylinder 25 pushes the movable block 24 to move so that the camera 22 gradually approaches the pressure gauge body 46, so that the pressure gauge body 46 is completely presented in the camera 22.

[0050] Step 3, pressurize the pressure gauge body 46 through the air pump for calibration. When a certain value is reached, start the third air cylinder 51, the third air cylinder 51 drives the push plate 52 to move, the push plate 52 drives the knocking rod 53 to move, the knocking rod 53 knocks the pressure gauge body 46 through the gasket 54, and then recognizes it again through the camera 22. The final recognition result is compared and calculated with the standard pressure value of the high-precision pressure sensor to obtain various indication errors of the pressure instrument;

[0051] Step 4: If the pressure gauge body 46 has quality problems that cause it to explode during calibration, the movable cover 38 and the fixed cover 39 shield the exploded fragments, and start the second cylinder 48 to drive the connecting plate 44 to move downward, the connecting plate 44 drives the supporting plate 41 to move downward, the supporting plate 41 drives the clamping seat 45 and the pressure gauge body 46 to move, and when the supporting plate 41 and the connecting plate 44 move downward, they drive the limit rod 42 to slide inside the guide groove 18, so that the clamping seat 45 and the pressure gauge body 46 move downward stably. When the pressure gauge body 46 is at the corner of the guide groove 18, the limiting rod 42 at the bottom continues to move along the guide groove 18. At this time, the support plate 41 drives the clamping seat 45 and the pressure gauge body 46 to gradually tilt. Then the limiting rod 42 at the top reaches the corner of the guide groove 18. At this time, the support plate 41 is in the maximum tilt state, and the pressure gauge body 46 slides out of the clamping seat 45 by inertia, and finally falls on the guide plate 19 for collection, and the exploded fragments fall on the guide plate 310, and finally slide along the guide plate 310 into the guide plate 19 for collection;

[0052] Step 5. If the size of the pressure gauge body 46 is slightly larger and it is difficult for the pressure gauge body 46 to fall off when it is tilted, the support plate 41 drives the clamp seat 45 and the pressure gauge body 46 to move downward, and finally it is in a tilted state. When the pressure gauge body 46 is tilted, it gradually contacts the friction pad 64, and the support plate 41 continues to drive the pressure gauge body 46 to move. The pressure gauge body 46 and the friction pad 64 rub against each other, and the force generated by the friction causes the spring 62 to be gradually compressed. Finally, the pressure gauge body 46 is gradually pulled out of the clamp seat 45 and falls onto the guide plate 19 for collection.
