Description

Technical Field

[0001] This invention relates to the field of power machinery engineering technology, and more specifically, to a dynamic balancing and positioning device. Background Technology

[0002] Existing dynamic balancing devices typically rotatably mount a plumb bob pointer, protractor, angle pointer, and base on the same axis. The protractor has concentric outer and inner angle scales on its surface, with opposite angular directions. The angle pointer crosses both the inner and outer angle scales. The protractor and angle pointer rotate independently or synchronously relative to the base to accurately determine the angle.

[0003] However, existing dynamic balancing indicators generally have the following drawbacks:

[0004] 1. The dynamic balancing indicator can only be fitted onto the shaft from the end, which is inconvenient to install;

[0005] 2. Once the position indicated by the plumb bob is determined, the operator can only manually draw lines on the rotor, which is not only prone to errors but also inconvenient to operate. Summary of the Invention

[0006] The present invention aims to provide a dynamic balancing positioning device that is easy to install on a shaft and does not require manual marking, and allows for more accurate and convenient finding of adjustment points.

[0007] The embodiments of the present invention can be implemented as follows:

[0008] This invention provides a dynamic balancing positioning device, which includes:

[0009] The first angle plate has an arc-shaped hole, which is concentrically set with the first angle plate;

[0010] The second angle disk is connected to the arc-shaped hole by a fixing component. The second angle disk can rotate along the arc-shaped hole and is concentric with the first angle disk. The first angle disk has a first semi-circular hole on its edge, and the second angle disk has a second semi-circular hole on its edge. The first semi-circular hole and the second semi-circular hole can form a through hole for the rotor shaft to pass through.

[0011] The base is magnetically connected to the first or second angle disk, and a pointer is provided on the base to indicate the scale on the first or second angle disk.

[0012] A beam generator, mounted on the base, is used to emit a beam of light along the rotor's axial direction to position the rotor.

[0013] The beneficial effects of the dynamic balancing positioning device provided in this embodiment include:

[0014] 1. The second angle disk can rotate along the arc-shaped hole and is concentrically set with the first angle disk. During the process of installing the dynamic balancing positioning device onto the rotor shaft, the second angle disk can be rotated to a state where it at least partially overlaps with the first angle disk, so that the first and second angle disks can be directly installed from the side of the shaft. Then, the second angle disk can be rotated to form a complete disk with the first angle disk, so that the dynamic balancing positioning device can be sleeved onto the shaft, making installation convenient.

[0015] 2. In the process of finding the adjustment point using the dynamic balancing positioning device, the rotor is positioned by emitting a beam along the rotor axis through the beam generator, avoiding manual marking and making the adjustment point search more accurate and convenient.

[0016] In an optional embodiment, the arc of the arc hole is greater than or equal to 180°, the second angle disk can be rotated to completely coincide with the first angle disk, and the second angle disk can be rotated to form a complete disk with the first angle disk.

[0017] In an optional embodiment, the second angle plate has two spaced-apart connection holes, which are respectively connected to the arc-shaped hole by a fixing component.

[0018] In this way, the second angle plate is connected to the first angle plate through two fixing components, which can ensure that the installation position of the second angle plate is stable and will not rotate around the fixing component because only one fixing component is used.

[0019] In an optional embodiment, the fixing component includes a screw and a nut, the screw passing through a connecting hole and an arc-shaped hole, and the nut being screwed onto the screw.

[0020] In this way, the use of nuts allows operators to easily loosen or tighten them manually, making it convenient for operators to adjust the position of the second angle plate on the first angle plate.

[0021] In an optional embodiment, the base includes a base and a bracket, with a magnet embedded in the base for magnetic connection to a first angle disk or a second angle disk, and the bracket connected to the base by bolts.

[0022] In this way, the base is magnetically connected to the first or second angle disk, which not only makes assembly and disassembly convenient, but also makes it easy to adjust the angle of the base relative to the first or second angle disk, thus making it easy to adjust the angle of the pointer on the first or second angle disk.

[0023] In an optional embodiment, the base has a U-shaped structure and is used to hold the shaft. After the base is connected to the first angle plate or the second angle plate, the base and the first angle plate are concentrically arranged.

[0024] In this way, the base can be easily held on the shaft and is concentrically set with the first angle plate. Rotating the base around the shaft can adjust the angle of the pointer on the first or second angle plate. It is not only simple in structure but also easy to operate.

[0025] In an optional embodiment, the beam generator is rotatably connected to the bracket, and the plane of rotation of the beam generator is perpendicular to the first angle disk.

[0026] In this way, the first and second angle disks are perpendicular to the center line of the shaft, and the rotation plane of the beam generator is set coplanar with the center line of the shaft. After the dynamic balancing positioning device is fitted onto the shaft, the testing work can begin, reducing the work of device debugging.

[0027] In an optional embodiment, the support includes a first support, a second support, and a rotating shaft. The first support is connected to the base, and the second support is rotatably connected to the first support via the rotating shaft. The beam generator is connected to the second support, and the center line of the rotating shaft is parallel to the first angle disk.

[0028] By directly setting the center line of the rotating shaft parallel to the first angle disk, it can be ensured that the rotation plane of the beam generator is perpendicular to the first angle disk, which not only simplifies the structural design but also meets the operational requirements.

[0029] In an optional embodiment, two slots are provided at intervals on the base, and magnets are provided in both slots.

[0030] In this way, the base is magnetically attached to the first or second angle plate by two magnets, and will not rotate around the magnet if only one magnet is used.

[0031] In an alternative implementation, the pointer and the beam generator are located on the same radial direction as the first or second angle disk.

[0032] In this way, the direction indicated by the pointer is in the same plane as the beam emitted by the beam generator, that is, the beam emitted by the beam generator rotates synchronously with the pointer, making it easy to find the correct angle. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0046] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0047] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0048] Please refer to Figures 1 to 5 This embodiment provides a dynamic balancing positioning device 100, which includes a first angle disk 1, a second angle disk 2, a base 3, and a beam generator 4.

[0049] Neither the first angle disk 1 nor the second angle disk 2 is a complete circular disk. The arc of the first angle disk 1 can be greater than or equal to 180°, and the arc of the second angle disk 2 can be less than 180°.

[0050] The first angle disk 1 has an arc-shaped hole 11, which is concentrically arranged with the first angle disk 1. The second angle disk 2 is connected to the arc-shaped hole 11 by a fixing component 5. The second angle disk 2 can rotate along the arc-shaped hole 11 and is concentrically arranged with the first angle disk 1. The first angle disk 1 has a first semi-circular hole 12 on its edge, and the second angle disk 2 has a second semi-circular hole 22 on its edge. When the second angle disk 2 rotates to form a complete disk with the first angle disk 1, the first semi-circular hole 12 and the second semi-circular hole 22 can form a through hole for the rotor shaft to pass through.

[0051] Preferably, the arc of the arc hole 11 is greater than or equal to 180°. The second angle disk 2 can be rotated to completely overlap with the first angle disk 1. At this time, the first semicircular hole 12 and the second semicircular hole 22 overlap and can be locked onto the shaft together. The second angle disk 2 can be rotated to form a complete disk with the first angle disk 1. At this time, the first semicircular hole 12 and the second semicircular hole 22 form a circular through hole.

[0052] In this way, during the process of installing the dynamic balancing positioning device 100 onto the rotor shaft, the second angle disk 2 can be rotated to a state where it completely overlaps with the first angle disk 1, so that the first angle disk 1 and the second angle disk 2 can be directly installed from the side of the shaft. Then, the second angle disk 2 can be rotated to form a complete disk with the first angle disk 1, thereby allowing the dynamic balancing positioning device 100 to be fitted onto the shaft, which is convenient for installation.

[0053] The base 3 is magnetically connected to either the first angle disk 1 or the second angle disk 2. A pointer is provided on the base 3 to indicate the scale on the first angle disk 1 or the second angle disk 2. A beam generator 4 is mounted on the base 3 and is used to emit a beam 41 along the rotor axis to position the rotor.

[0054] In this way, during the process of finding the adjustment point using the dynamic balancing positioning device 100, the beam generator 4 emits a beam 41 along the rotor axis to position the rotor, avoiding manual marking and making the search for the adjustment point more accurate and convenient.

[0055] Please see Figure 2 and Figure 4 The second angle disk 2 has two spaced-apart connecting holes 21, which are connected to the arc-shaped hole 11 via fixing components 5. In this way, the second angle disk 2 is connected to the first angle disk 1 via two fixing components 5, which ensures that the installation position of the second angle disk 2 is stable and will not rotate around the fixing component 5 if only one fixing component 5 is used.

[0056] The fixing component 5 includes a screw 51 and a nut 52, preferably a wing nut. The screw 51 passes through the connecting hole 21 and the arc-shaped hole 11, and the nut 52 is screwed onto the screw 51. In this way, the use of the nut 52 allows the operator to easily loosen or tighten the nut 52 manually, which facilitates the operator to adjust the position of the second angle plate 2 on the first angle plate 1.

[0057] Please see Figures 3 to 5 The base 3 includes a base 31 and a bracket 32. A magnet 312 is embedded in the base 31, which is used to magnetically connect to the first angle disk 1 or the second angle disk 2. The bracket 32 ​​is connected to the base 31 by bolts. In this way, the base 3 is magnetically connected to the first angle disk 1 or the second angle disk 2, which not only facilitates assembly and disassembly, but also makes it easy to adjust the angle of the base 3 relative to the first angle disk 1 or the second angle disk 2, that is, to adjust the angle of the pointer on the first angle disk 1 or the second angle disk 2.

[0058] The beam generator 4 is rotatably connected to the bracket 32, and the rotation plane of the beam generator 4 is perpendicular to the first angle disk 1. In this way, the first angle disk 1 and the second angle disk 2 are perpendicular to the center line of the shaft, and the rotation plane of the beam generator 4 is set in the same plane as the center line of the shaft. After the dynamic balancing positioning device 100 is fitted onto the shaft, the testing work can begin, reducing the work of device debugging.

[0059] The support 32 includes a first support 321, a second support 322, and a rotating shaft 323. The first support 321 is connected to the base 31, and the second support 322 is rotatably connected to the first support 321 via the rotating shaft 323. The beam generator 4 is connected to the second support 322, and the center line of the rotating shaft 323 is parallel to the first angle disk 1. By directly setting the center line of the rotating shaft 323 parallel to the first angle disk 1, it is ensured that the rotation plane of the beam generator 4 is perpendicular to the first angle disk 1, which not only simplifies the structural design but also meets the operational requirements.

[0060] Please see Figure 5 The base 31 has two slots 311 spaced apart, located on the surface of the base 31 near the first angle disk 1 or the second angle disk 2. A magnet 312 is installed in each slot 311. Thus, the base 31 is magnetically attracted to the first angle disk 1 or the second angle disk 2 by the two magnets 312, and will not rotate around the magnet 312 if only one magnet 312 is used.

[0061] Please see Figure 6 The two slots 311 can also be formed on the inner surface of the base 31 near the shaft. The slots 311 can be through holes or grooves, and magnets 312 are provided in both slots 311. In this way, the base 31 is magnetically attracted to the shaft by the two magnets 312.

[0062] Please see Figure 7 Alternatively, slots 311 can be formed on the surface of the base 31 near the shaft. The slots 311 can extend along the surface of the base 31, and magnets 312 are provided in each slot. In this way, the base 31 is magnetically attracted to both the shaft and the angle plate by the magnets 312.

[0063] Please see Figure 2 The base 31 has a U-shaped structure and is used to hold the shaft. After the base 31 is connected to the first angle disk 1 or the second angle disk 2, the base 31 is concentrically set with the first angle disk 1. In this way, the base 31 can be easily held on the shaft, and since it is concentrically set with the first angle disk 1, rotating the base 31 around the shaft can adjust the angle of the pointer on the first angle disk 1 or the second angle disk 2. It is not only simple in structure, but also easy to operate.

[0064] The pointer and the beam generator 4 are located on the same radial direction as the first angle disk 1 or the second angle disk 2. In this way, the direction indicated by the pointer and the beam 41 emitted by the beam generator 4 are in the same plane, that is, the beam 41 emitted by the beam generator 4 rotates synchronously with the pointer, which makes it easy to find the correct angle.

[0065] The working process of the dynamic balancing positioning device 100 provided in this embodiment:

[0066] First, the second angle disk 2 is rotated to a state where it completely overlaps with the first angle disk 1, so that the first angle disk 1 and the second angle disk 2 can be directly installed from the side of the shaft. Then, the second angle disk 2 is rotated to form a complete disk with the first angle disk 1, so that the dynamic balancing positioning device 100 is fitted onto the shaft.

[0067] Then, the base 3 and the beam generator 4 are clamped onto the shaft and magnetically attached to the first angle disk 1 or the second angle disk 2;

[0068] Finally, rotate the base 3 around the shaft to adjust the angle of the beam generator 4 and the pointer on the first angle disk 1 or the second angle disk 2, and rotate the beam generator 4 around the rotating shaft 323 so that the beam 41 of the beam generator 4 is emitted along the axial direction of the rotor to find the adjustment point.

[0069] The beneficial effects of the dynamic balancing positioning device 100 provided in this embodiment include:

[0070] 1. The second angle disk 2 can rotate along the arc-shaped hole 11 and is concentrically set with the first angle disk 1. During the process of installing the dynamic balancing positioning device 100 onto the rotor shaft, the second angle disk 2 can be rotated to a state where it completely overlaps with the first angle disk 1, so that the first angle disk 1 and the second angle disk 2 can be directly installed from the side of the shaft. Then, the second angle disk 2 can be rotated to form a complete disk with the first angle disk 1, so that the dynamic balancing positioning device 100 can be sleeved onto the shaft, which is convenient for installation.

[0071] 2. During the process of finding the adjustment point using the dynamic balancing positioning device 100, the beam generator 4 emits a beam 41 along the rotor axis to position the rotor, avoiding manual marking and making the adjustment point search more accurate and convenient.

[0072] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
