For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0020] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] In the description of this technology, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0022] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0023] See also Figure 1-4The utility model discloses an automatic alignment device for a pump coupling, comprising a base 1 and a laser centering instrument, the laser centering instrument comprising a pump end measuring device 5 and a motor end measuring device 8, a mounting seat 2 is arranged on one side of the top of the base 1, a water pump 3 is fixedly connected to the left side of the top of the mounting seat 2, a driving motor 6 is movably connected to the right side of the top of the mounting seat 2, a pump end half coupling 4 and a motor end half coupling 7 are respectively installed on the shaft ends of the water pump 3 and the driving motor 6, the pump end measuring device 5 and the motor end measuring device 8 are respectively installed and fixed on the surfaces of the pump end half coupling 4 and the motor end half coupling 7, an adjustment mechanism is arranged on the top of the base 1 for adjusting the position of the driving motor 6, a clamping mechanism is rotatably connected to the driving motor 6 for fixing the position of the driving motor 6, a support frame 18 is arranged on the other side of the top of the base 1, and a controller 19 is installed on the top of the support frame 18.

[0024] In this embodiment, the adjustment mechanism includes four mounting plates 10 and four first hydraulic rods 9. The four mounting plates 10 are respectively fixedly connected to the top of the base 1 and close to the positions around the driving motor 6. The first hydraulic rod 9 is fixedly connected to the surface of the mounting plate 10. The output ends of the four first hydraulic rods 9 are all facing the center of the driving motor 6. The output end of the first hydraulic rod 9 passes through the mounting plate 10 and is fixedly connected to the first pressure plate 11.

[0025] When the device is used to align the motor-end half coupling 7 and the pump-end half coupling 4, the output ends of the four first hydraulic rods 9 are first controlled by the controller 19, and the position of the motor-end half coupling 7 is adjusted by the extension and contraction of the first hydraulic rods 9. At this time, the pump-end measuring device 5 and the motor-end measuring device 8 in the laser alignment instrument are used to determine whether the position of the drive motor 6 is aligned. When the position of the drive motor 6 is aligned, the action of the first hydraulic rod 9 is stopped.

[0026] It should be noted that the laser alignment instrument is a high-precision tool used for the installation and inspection of power rotating equipment. The working principle of the laser alignment instrument is to install measuring devices that can simultaneously send and receive laser beams on the A-axis and B-axis respectively. The light beams are emitted from the lasers on the A-axis and B-axis and received by the other party. When the light beam falls on the photoelectric dot matrix CCD acquisition surface of the receiver, a very small irradiation area is formed. The instrument host determines the energy center point of the irradiation area through calculation. As the axis rotates, the energy center point of the light beam also moves on the CCD acquisition surface of the other receiver. The instrument calculates the axial deviation and angular deviation of the equipment under test based on these displacements, and thus performs alignment adjustments.

[0027] In this embodiment, in order to lock the drive motor 6 after adjusting the position, the clamping mechanism includes four rotating plates 13 and four second hydraulic rods 14. The drive motor 6 is fixedly connected with a connecting shaft 12 near the four corners. One end of the rotating plate 13 is rotatably connected to the connecting shaft 12. The second hydraulic rod 14 is fixedly connected to the other end of the rotating plate 13. The bottom of the output end of the second hydraulic rod 14 passes through the bottom of the rotating plate 13 and is installed with a second pressing plate 17. The top of the second pressing plate 17 is fixedly connected with a connecting rod 15. The top of the connecting rod 15 is fixedly connected with a connecting sleeve 16. The connecting sleeve 16 is fixedly connected to the output end of the second hydraulic rod 14 by bolts.

[0028] When the position of the driving motor 6 is adjusted, the center of the pump-end half coupling 4 and the center of the motor-end half coupling 7 are on the same horizontal plane. Then the second hydraulic rod 14 is started by the controller 19 to move the output end of the second hydraulic rod 14 downward until the second pressure plate 17 is pressed against the surface of the base 1, thereby fixing the driving motor 6 and ensuring that the subsequent bolt tightening steps will not affect the alignment and centering. Using this device, the pump-end half coupling 4 can be quickly aligned and centered with a high level of accuracy, and the operation is simple and does not require high operator skills.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
