[0026] Such as Figure 1 、 2As shown in the figure, the utility model discloses an auxiliary device for installing an inner ring of a valve, which comprises an operation table 1, two valve holders 2, two first clamping mechanisms, a second clamping mechanism, and a position control mechanism. Among them, an arc-shaped groove 21 is provided on the valve holder 2, and the axes of the arc-shaped grooves 21 on the two valve holders 2 are placed on the same straight line to achieve rough positioning of the valve. The flanges at both ends of the valve are generally circular rings, and the arc-shaped groove 21 is provided on the valve holder 2 to fit with the edge of the valve flange, improving stability. The two first clamping mechanisms are respectively arranged on both sides of the two valve holders 2 to clamp and fix both ends of the valve. The first clamping mechanism includes a first pressing plate 31 perpendicular to the axis of the arc-shaped groove 21, a first electric cylinder 32 for driving the first pressing plate 31 to move along the axis of the arc-shaped groove 21, and a fixing bracket 33 arranged on the operation table 1 and used for fixing the first electric cylinder 32. The second clamping mechanism includes a second pressing plate 41 and a second electric cylinder 42 for driving the second pressing plate to move in a direction perpendicular to the axis of the arc-shaped groove 21. The position control mechanism is arranged on the operation table 1 and used for controlling the second clamping mechanism to move on a plane parallel to the operation table 1.

[0027] The valve holder 2 can be fixed on the operation table 1. At this time, the arc-shaped groove 21 only needs to be larger than the thickness of the valve flange of the corresponding model. In order to facilitate the replacement of the valve holder 2 directly corresponding to the valve flange and facilitate the adjustment of the position of the valve holder 2, a groove 11 is provided on the operation table 1, and the valve holder 2 is movably arranged in the groove 11.

[0028] To improve safety, a protective cover 51 is provided on the operation table 1, and an operation port is provided on the protective cover 51. The protective cover 51 protects the equipment from external environmental pollution, thus ensuring the stable operation of the equipment and extending its service life, and can also improve the safety of use.

[0029] To facilitate operation and realize the installation of the valve under conditions with limited light, a light strip 52 is provided on the operation port. Preferably, as Figure 1 shown, the light strips 52 are arranged on both sides of the operation port at the same time. The light strip 52 can also be used as a status prompt component. For example, when the pressure is too high, the temperature is too high, or there is an operation error, etc., the light strip 52 is used for prompting to prompt the operator to take corresponding emergency measures, thereby effectively avoiding the occurrence of accidents and ensuring the safety and controllability of the operation process.

[0030] To improve the stability and control accuracy of the control of the second clamping mechanism, the position control mechanism includes a lead screw 61, a drive motor for driving the rotation of the lead screw 61, a coupling 62 for connecting the drive motor and the lead screw 61, a connecting block 63 sleeved on the lead screw 61, a guide rail 64 fixed on the operating table 1 and arranged parallel to the lead screw 61, a slider 65 placed on the guide rail 64 and moving along the guide rail 64, and a fixing bracket connected to both the connecting block and the slider 65.

[0031] The position control mechanism is driven by a lead screw. The rotation of the lead screw drives the connecting block 63 to move along the lead screw. High-precision control can be achieved by adjusting the pitch and diameter of the lead screw. The fixing bracket is simultaneously arranged on the connecting block and the slider 65, improving the stability of the fixing bracket and thus the installation quality of the inner ring of the valve.

[0032] To further improve the stability, there are two guide rails 64, which are respectively arranged on both sides of the lead screw 61.

[0033] During installation, to improve the machining accuracy, the midpoint of the straight line passing through the centers of the two first pressing plates 31 is placed on the vertical plane passing through the center of the second pressing plate 41. The first electric cylinders 32 of the two first clamping mechanisms are connected to the same control mechanism to achieve synchronous driving, ensuring the synchronous movement of the two first clamping mechanisms, and achieving synchronous and symmetric clamping of the valve to ensure centering.

[0034] The two first electric cylinders 32 are symmetrically installed on both sides of the valve, providing a stable and balanced clamping force through precise control, effectively preventing the valve from shifting or tilting during operation, and thus ensuring the centering of the valve.

[0035] With the above structure, the operation process is as follows:

[0036] First, place the valve on the valve holder. As Figure 3 shown, control the synchronous movement of the two first clamping mechanisms, smoothly push the valve body to the exact middle position of the tooling and then clamp it, ensuring that the valve is at the accurate installation starting point. Place the inner ring of the valve smoothly on the valve port.

[0037] Next, the position control mechanism controls the second clamping mechanism to move towards one side of the valve until the center of the second pressing plate 41 is aligned with the center of the valve port. Start the second electric cylinder 42 to control the second pressing plate to press down, so that the inner ring of the valve is accurately installed on the valve seat. During the pressing process, if the center of the second pressing plate 41 is not aligned with the center of the valve port, fine adjustment is performed to ensure the installation quality.

[0038] After the installation is completed, lift the second pressing plate to check the installation position of the inner ring of the valve and confirm that it has been firmly and accurately installed on the valve seat.

[0039] After completing the installation of the inner ring of the valve, control the two first clamping mechanisms to loosen the valve, and then remove the valve.

[0040] Through the above steps, it can be ensured that the inner ring of the valve is accurately and firmly pressed into the predetermined position, providing a stable guarantee for the subsequent normal operation of the valve.

[0041] With the above structure, its components are reasonably designed and compactly arranged, effectively reducing the overall size and mass, facilitating installation, and improving the installation accuracy and efficiency of the inner ring of the valve.

[0042] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
