Description

TECHNICAL FIELD

[0001] The utility model relates to fastener technical field, concretely relates to a nut plate. BACKGROUND

[0002] In the field of modern mechanical manufacturing and assembly, efficient and precise connection methods are crucial to ensure the quality and performance of mechanical equipment. Nut plate, as a commonly used connecting part, plays an important role in the assembly of mechanical structure.

[0003] Traditional nut plate usually has one or more nuts fixed on the plate-shaped part. This design meets the basic needs of mechanical assembly to some extent, providing convenience for bolt installation and improving assembly efficiency. For example, in automobile manufacturing, nut plate is widely used in the connection of vehicle body parts, enabling different metal plates to be quickly and firmly combined together. In the assembly process of industrial equipment, nut plate is also commonly used to fix various brackets and structural parts, ensuring the stability and reliability of the equipment.

[0004] However, with the continuous development of mechanical manufacturing technology and the increasing demand for assembly precision, the existing nut plate gradually exposes some shortcomings. The most prominent problem is that the nut position on the plate body of the existing nut plate is fixed. In the actual assembly process, due to manufacturing errors, installation deviations or design changes, the position of the bolt may deviate from the nut position on the nut plate. In this case, the traditional nut plate cannot be adjusted, causing great trouble to the assembly work.

[0005] On the one hand, when the bolt position deviates from the nut position, it may be necessary to rework the mechanical parts or adjust the installation position, which not only increases the production cost, but also consumes a lot of time and manpower. For example, in the assembly of some precision mechanical equipment, the assembly precision is very high in order to ensure the precise fit of each part. If the nut position on the nut plate cannot be adjusted, once the deviation occurs, the entire mechanical structure may need to be redesigned and manufactured, which undoubtedly brings huge economic losses to the enterprise.

[0006] On the other hand, in some large-scale mechanical equipment installation sites, due to space limitations and the complexity of the equipment, it is often very difficult to adjust the bolt position. And the existing nut plate cannot meet the demand of adjusting the nut position, which makes the assembly work more complex and difficult. For example, in the installation process of large-scale cranes, the size and weight of each part are very large. Once the nut position on the nut plate does not match the bolt position, it will be very troublesome to adjust, and even large-scale lifting equipment may be needed to assist in installation, which not only increases the installation cost, but also affects the progress of the project.

[0007] In summary, the existing nut plate cannot adapt to the deviation of bolt position because the nut position is fixed, and cannot meet the demand of high-precision and high-efficiency connection mode in modern mechanical manufacturing and assembly field. Therefore, it is of important practical significance to develop a new type of nut plate capable of adjusting the nut position. SUMMARY

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without the creative labor belong to the protection scope of the utility model.

[0027] The following references Figures 1-4 The utility model is described as follows:

[0028] Embodiment: a nut plate comprises a plate body and a nut 1.

[0029] The nut 1 is a cylindrical structure, and the center of the nut 1 is provided with a threaded hole. The nut plate is mainly composed of the plate body and the nut 1. The plate body serves as a basic support component and provides a platform for the nut 1 to install and connect. The nut 1 is a cylindrical structure, and this shape design makes it have good stability and reliability during installation and use. The center of the nut 1 is provided with a threaded hole for cooperation with the bolt to realize the connection and fixation of mechanical components.

[0030] The outer side of the nut 1 is provided with an annular connecting groove 2. This connecting groove 2 cooperates with the mounting groove 3 on the plate body, so that the nut 1 can be stably connected to the plate body while being able to adjust the position. The annular design of the connecting groove 2 ensures that the nut 1 can be well connected with the plate body in all directions, and will not loosen or fall off due to uneven stress.

[0031] The plate body is provided with a mounting groove 3 penetrating through both sides, which is long strip-shaped, and the length of the mounting groove 3 is greater than the outer diameter of the nut 1. The nut 1 is connected in the mounting groove 3, which allows the nut 1 to move freely in the mounting groove 3, thereby realizing the adjustment of the position. The long strip-shaped mounting groove 3 provides sufficient space for the movement of the nut 1, while ensuring the stability of the nut 1 during movement.

[0032] The side of the mounting groove 3 is connected in the connecting groove 2. This connection mode not only ensures the firm connection of the nut 1 with the plate body, but also allows the nut 1 to move smoothly in the mounting groove 3.

[0033] The nut 1 can move along the mounting groove 3 to adjust the position, which is an important innovation of the nut plate. In the actual mechanical manufacturing and assembly process, due to various reasons, the position of the bolt may deviate from the position of the nut. The position-adjustable nut plate can well solve this problem. When the bolt position does not match the nut position, only need to move the nut 1 to align with the bolt position, so that the assembly work can be easily completed. This position adjustment function greatly improves the assembly efficiency, reduces the reprocessing and adjustment work caused by position deviation, and reduces the production cost.

[0034] The nut 1 can move along the mounting groove 3 to adjust the position, and the nut 1 is provided with at least one. According to different mechanical part connection requirements, multiple nuts 1 can be provided on the plate body. The setting of multiple nuts 1 can improve the connection strength and stability of the nut plate, and also can meet the connection requirements of mechanical parts of different sizes and shapes.

[0035] This nut plate realizes the adjustable function of the nut position through unique structural design, and provides a high-efficiency and convenient connection solution for the field of mechanical manufacturing and assembly. It has the advantages of simple structure, convenient use, flexible adjustment, etc., and has broad application prospects in the field of mechanical manufacturing and assembly in the future.

[0036] The plate body includes a first plate body 4 and a second plate body 5; the first plate body 4 is composed of two left and right plate pieces 41, which increases the flexibility and assembly of the plate body structure. The opposite faces of the two plate pieces 41 are respectively provided with grooves 42, and the two grooves 42 are combined into an installation slot 3; this design makes it easier to form the installation slot 3, and also facilitates accurate control of the size and shape of the installation slot 3. The second plate body 5 is fixedly connected with the first plate body 4 by welding, which strengthens the stability of the plate body structure. The second plate body 5 is provided with a through slot 6 corresponding to the installation slot 3, and the width of the through slot 6 is equal to or greater than the outer diameter of the nut 1. Such a design allows the nut 1 to move freely in the installation slot 3 and the through slot 6, while ensuring the stability of the nut 1 during movement. The second plate body 5 is flush with one end of the nut 1, making the overall structure of the nut plate more compact and the appearance more beautiful.

[0037] In the manufacture of the nut plate of the present application, the process of first completing the assembly of the plate piece 41 and the nut 1, and then welding the plate body, is adopted. This process has the following advantages:

[0038] Improve assembly accuracy: connecting the two plate pieces 41 with the connecting slot 2 on the nut 1 first can more accurately control the position of the nut 1 in the installation slot 3, ensuring smooth movement of the nut 1. Then welding can avoid affecting the position of the nut 1 during welding, thereby improving the assembly accuracy of the nut plate.

[0039] Convenient production operation: separating the assembly and welding processes makes production operation more convenient. In the assembly process, more attention can be paid to the connection of the nut 1 and the plate piece 41 to ensure the firmness and stability of the connection. In the welding process, more attention can be paid to the welding quality of the plate body to ensure that the welded plate body structure is firm and reliable.

[0040] Improve production efficiency: this process can realize assembly line operation and improve production efficiency. In the assembly process, multiple nuts 1 and plate pieces 41 can be assembled at the same time, and then the assembled components can be welded and fixed. This can greatly shorten the production cycle and improve the production efficiency.

[0041] The width of the installation slot 3 is equal to the inner diameter of the connecting slot 2. This setting allows the nut 1 to adjust its position along the length of the installation slot 3. First, from the perspective of structural cooperation, when the width of the installation slot 3 is equal to the inner diameter of the connecting slot 2, the nut 1 can be tightly and stably connected with the plate body. The annular connecting slot 2 on the outer side of the nut 1 can perfectly fit the side of the installation slot 3, which ensures that the nut 1 does not shake or loosen in the installation slot 3, ensuring the stability and reliability of the nut plate during use.

[0042] Secondly, this setting is crucial for the position adjustment function. Since the installation groove 3 is long and its width is equal to the inner diameter of the connecting groove 2, the nut 1 can be smoothly adjusted in the length direction of the installation groove 3. In the actual mechanical manufacturing and assembly process, when the position of the bolt does not match the initial position of the nut 1, the operator can easily push the nut 1 along the installation groove 3 to align it with the bolt position. This adjustability greatly improves the flexibility and efficiency of assembly, reduces rework and adjustment due to position deviation, and reduces production costs.

[0043] In addition, from the perspective of design rationality, the size matching of the installation groove 3 and the connecting groove 2 makes the structure of the entire nut plate more compact. There is no problem of excessive or insufficient gap due to size mismatch, which not only ensures the movement space of the nut 1, but also does not make the overall size of the nut plate too large, facilitating installation and use in various mechanical structures.

[0044] The width of the installation groove 3 is greater than the inner diameter of the connecting groove 2, and the width of the installation groove 3 is less than the outer diameter of the connecting groove 2. This setting allows the nut 1 to be adjusted in both the length direction and the width direction of the installation groove 3. Similar to the case where the width of the installation groove 3 is equal to the inner diameter of the connecting groove 2, this size relationship also ensures that the nut 1 can be adjusted in the length direction of the installation groove 3. Since the installation groove 3 is long, the nut 1 can move freely in the length direction to adapt to the position requirements of the bolt in different situations. In the mechanical manufacturing and assembly process, when the bolt position deviates in the length direction, the operator can easily push the nut 1 along the length direction of the installation groove 3 to align it with the bolt position, thereby improving the efficiency and accuracy of assembly.

[0045] More importantly, this size relationship allows the nut 1 to be adjusted in the width direction of the installation groove 3. When the width of the installation groove 3 is greater than the inner diameter of the connecting groove 2 and less than the outer diameter of the connecting groove 2, the nut 1 has a certain space for movement in the installation groove 3. In practical applications, if the position of the bolt also deviates in the width direction, the nut 1 can be fine-tuned in the width direction of the installation groove 3, further increasing the adaptability and flexibility of the nut plate.

[0046] The first plate body 4 is provided with a plurality of first welding holes 7, and the second plate body 5 is provided with second welding holes 8 corresponding to the first welding holes 7, and the diameter of the second welding holes 8 is smaller than that of the first welding holes 7. When the first plate body 4 and the second plate body 5 are welded, welding is performed at the first welding holes 7, and solder enters the first welding holes 7 and the second welding holes 8, forming a firm connection and performing deburring.

[0047] First, the first plate body 4 is provided with a plurality of first welding holes 7. The setting of these welding holes provides specific welding positions for the welding of the first plate body 4 and the second plate body 5. By welding at these pre-set positions, the accuracy and stability of the welding can be ensured. At the same time, the setting of multiple welding holes can increase the contact area of the welding, improve the strength and firmness of the welding.

[0048] The second plate body 5 is provided with second welding holes 8 corresponding to the first welding holes 7, and the diameter of the second welding holes 8 is smaller than that of the first welding holes 7. This design has many advantages. On the one hand, the smaller diameter of the second welding hole 8 can guide the solder during the welding process. When welding, the solder will first flow into the larger diameter first welding hole 7, and then due to capillary action and other factors, the solder will further flow into the smaller diameter second welding hole 8. This can ensure that the solder fills the space between the two welding holes and forms a firm connection. On the other hand, this design of different size welding holes can prevent excessive solder overflow to some extent, keeping the welding area clean and beautiful.

[0049] During the welding process, solder enters the first welding hole 7 and the second welding hole 8, forming a firm connection. This welding method can effectively combine the first plate body 4 and the second plate body 5, ensuring that the nut plate will not separate during use. At the same time, the connection after welding has high strength and stability, and can withstand large mechanical stress.

[0050] In addition, deburring treatment is also carried out after welding. Deburring is an important process that can remove burrs and excess solder produced during welding. The presence of burrs can affect the appearance quality of the nut plate and may interfere with the installation and operation of mechanical parts in some cases. Through deburring, the surface of the nut plate can be smoother and more uniform, improving the quality and reliability of the product.

[0051] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
