Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, specifically an adjustable turbine shaft assembly tool. Background Technology

[0002] During the assembly of a water turbine, the traditional method of installing and disassembling bushings usually involves using an adjustable screw to support the inner wall of the bushing at two points. This method has poor stability, and the rotation of the screw during lifting can easily cause scratches on the inner surface of the bushing. Since the inner surface of the bushing is a precision-machined surface, repairing scratches requires multiple welding and grinding operations. Furthermore, it is difficult to guarantee the inner diameter and accuracy, resulting in a significant waste of manpower, resources, and production time, and affecting the appearance and assembly quality.

[0003] Therefore, it is necessary to design an adjustable turbine shaft assembly tool to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model provides an adjustable turbine shaft assembly tool, which is convenient to use, low in cost, safe and stable, and highly versatile. It can improve assembly efficiency and ensure the dimensional accuracy and appearance quality of the shaft sleeve.

[0005] To achieve the above objectives, this utility model employs the following technical solution: An adjustable turbine shaft sleeve assembly tool includes a center plate. The center plate has a plurality of pin holes spaced circumferentially on its sidewalls. The top of the center plate has a plurality of adjustment holes corresponding to the pin holes. The adjustment holes communicate with the pin holes. A slider is slidably connected to each pin hole. The outer end of the slider can engage with a groove on the inner wall of the shaft sleeve. A threaded rod is connected to the slider, passing through the adjustment holes and movable within them. A locking nut is threadedly connected to the threaded rod, and the locking nut abuts against the top of the center plate.

[0006] Preferably, the pin holes are three that are equally spaced along the circumference of the center plate.

[0007] Preferably, the threaded rod is threadedly connected to the slider.

[0008] Preferably, the adjustment hole is a U-shaped hole.

[0009] Preferably, a central lifting ring is provided at the top of the central plate.

[0010] Preferably, the central lifting ring is threadedly connected to the central plate.

[0011] Preferably, the top and bottom surfaces of the outer end of the slider are both planes, and the end face is an arc-shaped surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses an adjustable turbine shaft sleeve assembly tool. Several sliders are arranged circumferentially on a central plate. By moving a threaded rod, the position of the sliders is adjusted, allowing them to enter grooves on the inner wall of the shaft sleeve. All sliders are in contact with the inner wall of the grooves, forming multi-point support. A locking nut then locks the slider position, restricting axial movement of the central plate and circumferential rotation of the sliders. This ensures high stability and prevents damage to the inner wall of the shaft sleeve during lifting, guaranteeing the dimensional accuracy and appearance quality of the shaft sleeve. Furthermore, because the sliders are adjustable, it is suitable for shaft sleeves with different inner diameters. Attached Figure Description

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0017] Please see Figure 1 and Figure 2 An adjustable turbine shaft sleeve assembly tool includes a center plate 1. The center plate 1 has several pin holes 6 spaced circumferentially on its sidewalls. The center plate 1 has several adjusting holes 7 corresponding to the pin holes 6 on its top. The adjusting holes 7 communicate with the pin holes 6. A slider 2 is slidably connected to each pin hole 6. The outer end of the slider 2 can engage with a groove 8 on the inner wall of the shaft sleeve 5 (grooves on the inner wall of the shaft sleeve are existing technology). The slider 2 is connected to a threaded rod 3, which passes through the adjusting holes 7 and can move within them. A locking nut 4 is threadedly connected to the threaded rod 3, and the locking nut 4 abuts against the top of the center plate 1.

[0018] The adjustable turbine shaft sleeve assembly tool of this embodiment uses several sliders 2 arranged circumferentially on the center plate 1. By moving the threaded rod 3, the position of the sliders 2 is adjusted so that they enter the grooves 8 on the inner wall of the shaft sleeve. All the sliders 2 are in contact with the inner wall of the grooves 8, forming multi-point support. Then, the position of the sliders 2 is locked by tightening the locking nut 4, which restricts the axial movement of the center plate 1 and the circumferential rotation of the sliders 2. This ensures high stability and prevents damage to the inner wall of the shaft sleeve during lifting, thus guaranteeing the dimensional accuracy and appearance quality of the shaft sleeve. Furthermore, since the sliders 2 are adjustable, it can be used for shaft sleeves with different inner diameters.

[0019] In some optional embodiments, the pin holes 6 are three that are equally spaced along the circumference of the center plate 1. This facilitates operation and provides better stability.

[0020] In some optional embodiments, the threaded rod 3 is threadedly connected to the slider 2, and the slider 2 is provided with a threaded hole for connection with the threaded rod 3, which facilitates installation and disassembly.

[0021] In some alternative embodiments, the adjustment hole 7 is a U-shaped hole and is located at the edge of the center plate 1.

[0022] In some optional embodiments, a central lifting ring 9 is provided at the top of the central plate 1, through which the bushing is lifted. Specifically, the central lifting ring 9 is threadedly connected to the central plate 1. A lifting ring screw can be used to screw onto the center of the top of the central plate 1.

[0023] In some optional embodiments, the top and bottom surfaces of the outer end of the slider 2 are both flat, which cooperate with the bushing groove 8. The end face of the outer end of the slider 2 is an arc-shaped surface, and the radius of the arc is equal to the radius of the bushing inner wall groove 8, so as to increase the contact area with the inner wall of the groove 8, form surface contact, and avoid scratches.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this utility model is defined by the claims and their equivalents.
