However, the center of the weights with different specifications is provided with holes with different diameters, and the center of the weights with different specifications is provided with small holes, so that the weights with different specifications cannot be fixed through the rod because the holes with different diameters are large and cannot be unified. When examining, piston pressure vacuum gauge can rotate, and the weight that does not have the fixed is because of unable assurance absolute concentricity, can take place the slip skew, leads to the system unstable. Unless the tray is provided with a clamping groove with proper size to clamp the periphery of the weight, otherwise, the weight can slide and deviate to the side when rotating a little non-concentric, but the clamping groove is arranged on the tray, so that the weight with fixed specification can be placed, and the weight can not adapt to various detected conditions.

Examples
In the embodiment, a piston type pressure vacuum gauge is used as an application carrier of the concentric state monitoring and adjusting device for the rotation test. The device of the utility model can be used for detecting and adjusting the eccentric position of the hollow piece for rotation test, but is not limited to being applied to the detection of the piston type pressure vacuum gauge.
As shown in fig. 1, the concentric state monitoring and adjusting device for the rotation test comprises a base 1, wherein the base 1 is placed on a tray used for verification of a piston type pressure vacuum gauge, a central hole 2 is formed in the central position of the base 1 and used for fixing the base 1 on a vertical rod of the piston type pressure vacuum gauge, and the center of the base 1 is consistent with the center of the tray. The outer rotating member (weight) is hollow and the interior thereof may be of any shape.
The base 1 is provided with 4 groups of concentric monitoring and adjusting components for fixing an external rotating member (such as weights at the shadow in fig. 2), and the 4 groups of concentric monitoring and adjusting components can be independently adjusted to support the hollow inner wall of the external rotating member so as to fix the external rotating member. A pressure sensor 7 is arranged between the connecting rod 3 and the supporting rod 4, and the pressure sensor 7 is connected with the display component. In the rotation verification, a rotation eccentric value is obtained according to the data of the pressure sensor 7, the concentric monitoring and adjusting assembly is adjusted according to feedback information, so that the outer rotating member is in a concentric state when rotating in a regression mode, and if the inner part of the outer rotating member is in an irregular shape, the center of gravity of the outer rotating member is overlapped with the center of gravity of the piston type pressure vacuum gauge, the tray and the base through adjusting the concentric monitoring and adjusting assembly.
Specifically, the concentric monitoring and adjusting assembly comprises a movable connecting rod 3, and the connecting rod 3 is of a hexagonal structure so as to be convenient to fix and prevent rotation. One end of the connecting rod 3 faces the center hole 2, one end of the supporting rod 4 is connected to the other end of the connecting rod 3, and the other end of the supporting rod 4 is in contact with the hollow inner wall of the external rotating member. The base 1 is provided with a gear 5, and one side of the connecting rod 3 is provided with a gear groove 6 matched with the gear 5. The connecting rod 3 can be driven to move by rotating the gear 5. The eccentric state of the external rotating member can be monitored through the pressure sensor 7, and the pressure value is sent to the external display assembly for display in real time, so that the device can be cleared in real time.
For external rotating parts (with different sizes of central holes) with different specifications, the position of the supporting rod 4 can be adjusted through the rotating gear 5, so that the supporting rod 4 supports the hollow inner wall of the external rotating part, the rotating external rotating part can not slide and deviate in the verification process of the piston type pressure vacuum gauge, meanwhile, unbalanced opposite indication values are balanced through proper adjustment of the gear 5 according to the data of the pressure sensor 7, and the external rotating part is adjusted to a concentric rotating state.
