Description

Technical Field

[0001] This utility model relates to the field of coaxiality adjustment technology, and more specifically to a coupling coaxiality adjustment device. Background Technology

[0002] In existing large-scale electromechanical equipment, electric motors are often used to power other devices. Multiple transmission components between the motor and the working device are typically connected by couplings for power transmission. Due to factors such as transmission eccentricity, couplings require relatively frequent and complex replacement. Therefore, it is essential to ensure good coaxiality between all couplings. However, because different components have different dimensions, if the coaxiality accuracy does not meet the installation requirements, it can cause parts to run around, increase rotational inertia, and shorten the service life of the couplings. This can also affect the overall equipment, causing noise and even safety accidents. Therefore, coaxiality testing and adjustment during coupling installation is both necessary and essential.

[0003] For example, the prior art disclosure number CN222596285U discloses a coaxiality adjustment device for a hydraulic oil pump coupling. This utility model uses hydraulic jacking to adjust the motor base longitudinally and laterally, ensuring stable adjustment and easy adjustment even when dealing with large and heavy motors. Using a hand-cranked hydraulic pump in conjunction with a hydraulic jack, the motor base can be adjusted smoothly and effortlessly, without the need for multiple people to cooperate, greatly saving manpower. This utility model can be adapted to different types of hydraulic oil pumps, and each component can be adjusted according to the size of the pump. The entire device has a simple structure and high integration.

[0004] However, the existing technology described above still has the following problems in use: when adjusting the coaxiality of the coupling, the operator needs to hold a measuring ruler on the coupling to check, and then adjust the motor height according to the measurement results. This process requires the operator to frequently adjust the measuring ruler, which is time-consuming and labor-intensive. Based on this, the present invention provides a coupling coaxiality adjustment device with a measuring function. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a coupling coaxiality adjustment device. The device is fixed to a motor connected to the coupling via an arc-shaped connecting plate. This eliminates the need for operators to constantly hold the first telescopic plate, allowing the coaxiality of the coupling to be tested using a coaxiality measuring plate. This makes operation more time- and labor-saving. Furthermore, the lengths of the first and second telescopic plates are adjustable, facilitating the adjustment of the height of the arc-shaped connecting plate and the coaxiality measuring plate, thus improving practicality and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coupling coaxiality adjustment device, comprising a first telescopic plate, with a second telescopic plate fixedly mounted at both the front and rear ends of the first telescopic plate, and an arc-shaped connecting plate and a coaxiality measuring plate respectively mounted at the bottom of the two second telescopic plates for measuring the coaxiality of the coupling, wherein a connecting groove is provided at the top of the arc-shaped connecting plate and the top of the coaxiality measuring plate, the second telescopic plate is disposed inside the connecting groove and fixed by a first fastening bolt, and multiple equally spaced connecting holes are provided on both sides of the top of the arc-shaped connecting plate, thereby improving the connection strength between the arc-shaped connecting plate and the motor.

[0007] In a preferred embodiment, the first telescopic plate includes a first support plate, the front end of the first support plate is provided with a first adjustment groove, and the first adjustment groove is provided with a first extension plate. The distance between the two second telescopic plates is adjusted by adjusting the length of the first extension plate and the first support plate.

[0008] In a preferred embodiment, both second telescopic plates include a second support plate, which is fixed to the rear end of the first support plate and the front end of the first extension plate, respectively. A second adjustment groove is provided at the bottom of each of the two second support plates, and a second extension plate is provided inside the second adjustment groove. The two second extension plates are respectively located in the two connecting grooves. By adjusting the length of the second extension plate extending out of the second adjustment groove, the position of the arc-shaped connecting plate and the coaxiality measuring plate can be quickly adjusted.

[0009] In a preferred embodiment, the first support plate and the two second support plates are each threaded with a second fastening bolt on one side, and the first extension plate and the two second extension plates are each provided with a plurality of equally spaced threaded holes on one side. The second fastening bolts are threadedly connected to the threaded holes. By using the second fastening bolts to cooperate with the plurality of threaded holes, it is convenient for the staff to quickly adjust the total length of the first support plate and the first extension plate, and the second support plate and the second extension plate.

[0010] In a preferred embodiment, handles are fixedly provided on both sides of the first support plate and the second support plate. Each handle has anti-slip textures processed on its outer wall. The anti-slip textures increase the friction of the handle surface, thereby improving the anti-slip properties of the handle and making it more stable for the operator to hold the device.

[0011] In a preferred embodiment, the arc-shaped connecting plate is made of an elastic metal material, which gives the arc-shaped connecting plate a certain degree of flexibility, thereby better fixing it to the motor surface and improving the connection firmness.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a first telescopic plate and a second telescopic plate to support the arc-shaped connecting plate and the coaxiality measuring plate. The arc-shaped connecting plate is fixed to the motor connected to the coupling. The coaxiality of the coupling can be tested by the coaxiality measuring plate without the operator having to hold the first telescopic plate all the time. This makes the operation more time-saving and labor-saving. In addition, the lengths of the first telescopic plate and the second telescopic plate are adjustable, which makes it easy to adjust the height of the arc-shaped connecting plate and the coaxiality measuring plate, thus improving practicality.

[0014] 2. By designing the arc-shaped connecting plate and the coaxiality measuring plate to be detachable from the two second extension plates, it is easy for staff to quickly disassemble the arc-shaped connecting plate and the coaxiality measuring plate for cleaning and replacement. The structure is simple and very quick to use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a coupling coaxiality adjustment device, including a first telescopic plate 1, with a second telescopic plate 2 fixedly provided at both the front and rear ends of the first telescopic plate 1. The bottom of the two second telescopic plates 2 is respectively provided with an arc-shaped connecting plate 3 and a coaxiality measuring plate 4 for measuring the coaxiality of the coupling. In actual use, a wrench for loosening the first fastening bolt of the motor can also be placed on the coaxiality measuring plate 4. The operator can remove the wrench to loosen or tighten the first fastening bolt of the motor, thereby adjusting the height of the motor.

[0025] like Figure 3 As shown, the top of the arc-shaped connecting plate 3 and the top of the coaxiality measuring plate 4 are both provided with connecting grooves 5. The second telescopic plate 2 is located inside the connecting groove 5 and is fixed by the first fastening bolt 6. Multiple equally spaced connecting holes 7 are provided on both sides of the top of the arc-shaped connecting plate 3.

[0026] like Figure 2 As shown, the first telescopic plate 1 includes a first support plate 101, a first adjustment groove 102 is provided at the front end of the first support plate 101, and a first extension plate 103 is provided inside the first adjustment groove 102.

[0027] like Figure 3 As shown, both second telescopic plates 2 include a second support plate 201. The two second support plates 201 are respectively fixed to the rear end of the first support plate 101 and the front end of the first extension plate 103. The bottom of both second support plates 201 is provided with a second adjustment groove 202. The second adjustment groove 202 is provided with a second extension plate 203. The two second extension plates 203 are respectively provided in the two connecting grooves 5.

[0028] The first support plate 101 and the two second support plates 201 are threaded with second fastening bolts 8 on one side. The first extension plate 103 and the two second extension plates 203 are provided with multiple equally spaced threaded holes 9 on one side. The second fastening bolts 8 are threadedly connected to the threaded holes 9.

[0029] In actual use, the operator holds the first telescopic plate 1 and, as needed, pulls the first extension plate 103 out of the first adjustment slot 102. Then, the second fastening bolt 8 is used to fix it to the threaded hole 9 on the first extension plate 103, thereby adjusting the distance between the two second telescopic plates 2. Subsequently, the arc-shaped connecting plate 3 is fixed to the motor by bolts passing through multiple connecting holes 7. Then, the second extension plate 203 is pulled to adjust the total length of the second extension plate 203 and the second support plate 201, so that the coaxiality measuring plate 4 slowly descends and contacts the top of the coupling. The operator can quickly judge the coaxiality of the coupling by using the coaxiality measuring plate 4. If there is a gap between the bottom of the coaxiality measuring plate 4 and the top of one side of the coupling, it indicates that the coaxiality of the coupling is deviated. After adjusting the coupling, the operator uses the coaxiality measuring plate 4 to measure again. When the coaxiality measuring plate 4 is in close contact with the top of the coupling, it indicates that the adjustment is in place.

[0030] Furthermore, the staff can loosen the first fastening bolt 6, separate the arc-shaped connecting plate 3 and the coaxiality measuring plate 4 from the second extension plate 203, and then clean and replace them. When reinstalling, the second extension plate 203 is aligned with the connecting groove 5 and inserted, and the first fastening bolt 6 is tightened again.

[0031] Refer to the instruction manual appendix Figure 1 , Figure 4 and Figure 5 Both sides of the first support plate 101 and the second support plate 201 are fixedly provided with handles 10, and the outer wall of each handle 10 is processed with anti-slip texture.

[0032] The arc-shaped connecting plate 3 is made of elastic metal material, which gives the arc-shaped connecting plate 3 a certain degree of flexibility, thereby better fixing it to the surface of the motor and improving the connection firmness.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
