Description

Technical Field

[0001] This utility model relates to the field of nucleotide ammonolysis, specifically to a structure for welding electrodes with screws. Background Technology

[0002] Screw welding is a welding technique used to fix screws to metal workpieces, typically used when nuts are not required. This method not only improves assembly efficiency but can also provide better mechanical properties in some cases.

[0003] The existing upper shell cover screw welding upper electrode uses a polyurethane insert embedded in the upper electrode and an interference fit between the screw thread to hold the screw in place for welding. During the production process, it is prone to wear and produces white powder. When used for the first time, welding can easily cause the entire workpiece to get stuck, affecting efficiency. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a structure for welding an upper electrode with a screw. The screw is positioned by using a strong magnet to attract it, which facilitates operation and maintenance during the production process. It can also effectively avoid the frequent replacement of the inner polyurethane insert and the generation of impurities and foreign objects.

[0005] This utility model provides a structure for screw welding an upper electrode, including an upper electrode housing, a polyurethane insert embedded at one end of the upper electrode housing, a spring located below the polyurethane insert inside the upper electrode housing, a strong magnet located below the spring inside the upper electrode housing, and a screw extending into the upper electrode housing and attracted by the strong magnet at the other end of the upper electrode housing.

[0006] An insulating rubber ring, a strong magnet, and a spring are placed sequentially inside the upper electrode housing. Then, a polyurethane insert is embedded into the upper surface of the upper electrode housing. The polyurethane insert compresses the spring, which in turn pushes the strong magnet against the inner wall of the upper electrode housing. The shank of the screw is then inserted through the lower surface of the upper electrode housing. The strong magnet generates an upward attraction on the screw until the head of the screw abuts against the end face of the upper electrode housing. The two work together to form a clamping force, thus fixing the screw inside the upper electrode housing. This facilitates operation and maintenance during production and effectively avoids frequent replacement of the inner polyurethane insert and the generation of impurities and foreign objects.

[0007] As a further technical solution, the upper electrode housing is arranged in a stepped manner, and through holes one, two, and three are sequentially connected from top to bottom within the upper electrode housing. These sequentially connected through holes one, two, and three within the upper electrode housing provide installation space for polyurethane inserts, springs, strong magnets, and screws.

[0008] As a further technical solution, the polyurethane insert is interference-fitted into the through hole one of the upper electrode housing, and its end face is flush with the end face of the upper electrode housing. During installation, the polyurethane insert is embedded into the through hole one until its top surface is flush with the end face of the upper electrode housing, thus realizing the installation of the polyurethane insert.

[0009] As a further technical solution, the shank of the screw extends into the third through hole of the upper electrode housing, and its head abuts against the end face of the upper electrode housing. In use, by inserting the shank of the screw into the third through hole of the upper electrode, the strong magnet can generate an upward attraction force on the screw until the head of the screw abuts against the upper electrode, and the two form a clamping force, so that the screw is fixed in the upper electrode.

[0010] As a further technical solution, the size of the third through hole is adapted to the size of the shank of the screw. Furthermore, the third through hole can restrict the movement trajectory of the screw, preventing it from shifting laterally during installation and affecting subsequent use.

[0011] As a further technical solution, an insulating rubber ring is also provided inside the upper electrode housing, located below the strong magnet. The spring pushes the strong magnet against the insulating rubber ring, and the insulating rubber ring abuts against the inner wall plane of the second through hole. The insulating rubber ring can prevent the strong magnet from directly contacting the inner wall of the upper electrode housing, thus avoiding wear and affecting the service life of the strong magnet.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This electrode has a simple and reasonable structure, which is easy to manufacture and use. When in use, this structure is combined with a strong magnet to attract the screw for positioning, which facilitates operation and maintenance during the production process. It can also effectively avoid frequent replacement of the inner polyurethane insert and the generation of impurities and foreign objects.

[0014] 2. By setting a spring, the tension of the spring can prevent the magnet from easily shifting within the upper electrode, thus affecting the positioning effect of the screw.

[0015] 3. The polyurethane insert embedded in the upper electrode contact surface is used to protect the weldment and improve the electrode life. It can also absorb some vibration and noise, making the welding process more stable and reducing the impact on equipment and operating environment.

[0016] 4. An insulating rubber ring is installed between the strong magnet and the inner wall of the upper electrode to prevent the strong magnet from directly contacting the inner wall of the upper electrode, which would cause wear and affect the service life of the strong magnet.

[0021] The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and accompanying drawings of this utility model are intended to cover a non-exclusive inclusion, such as a process, method, system, product, or device that includes a series of steps or units, not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In addition, the technical features of the various embodiments or individual embodiments provided by this utility model can be arbitrarily combined to form new technical solutions. Such combinations are not bound by the order of steps and / or structural composition patterns, but must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] Please see Figure 1-2This utility model provides a structure for screw welding an upper electrode, including an upper electrode housing 1, a polyurethane insert 2 embedded at one end of the upper electrode housing 1, a spring 3 located below the polyurethane insert 2 inside the upper electrode housing 1, a strong magnet 4 located below the spring 3 inside the upper electrode housing 1, and a screw 5 extending into the upper electrode housing 1 and attracted by the strong magnet 4 at the other end of the upper electrode housing 1.

[0024] After the polyurethane insert 2 is embedded into one end of the upper electrode housing 1, the spring 3 is in a compressed state. The tension of the spring 3 allows the strong magnet 4 to adhere tightly to the inner wall plane of the upper electrode housing 1. One end of the screw 5 is inserted into the upper electrode housing 1 from the other end. The strong magnet 4 generates a magnetic attraction force to hold the screw, which can realize the rapid positioning of the screw 5, which is convenient for operation and maintenance in the production process. It can also effectively avoid frequent replacement of the inner polyurethane insert 2 and the generation of impurities and foreign objects.

[0025] The tension of spring 3 prevents the magnet from easily shifting within the upper electrode, thus affecting the positioning effect of screw 5.

[0026] In this embodiment, the upper electrode housing 1 is arranged in a stepped manner, and the upper electrode housing 1 has through holes 11, 12 and 13 connected sequentially from top to bottom.

[0027] The upper electrode housing 1 is typically made of a material with good electrical conductivity, such as copper alloy, to ensure effective current conduction. The through holes 11, 12, and 13 connected in sequence within the upper electrode housing 1 provide installation space for the polyurethane insert 2, spring 3, strong magnet 4, and screw.

[0028] In this embodiment, the polyurethane insert 2 is interference-fitted into the through hole 11 of the upper electrode housing 1, and its end face is flush with the end face of the upper electrode housing 1.

[0029] During installation, the polyurethane insert 2 is inserted into the through hole 11 until its top surface is flush with the end face of the upper electrode housing 1, thus achieving the installation of the polyurethane insert 2.

[0030] The polyurethane insert 2 embedded in the upper electrode contact surface is used to protect the weldment and improve the electrode life. It can also absorb some vibration and noise, making the welding process more stable and reducing the impact on equipment and operating environment.

[0031] In this embodiment, the shank of the screw 5 extends into the through hole 13 of the upper electrode housing 1, and its head abuts against the end face of the upper electrode housing 1. The size of the through hole 13 is adapted to the size of the shank of the screw 5.

[0032] In use, by inserting the shank of the screw 5 into the third through hole of the upper electrode, the strong magnet 4 can generate an upward attraction on the screw 5 until the head of the screw 5 abuts against the upper electrode, and the two form a clamping force, which fixes the screw 5 in the upper electrode. The third through hole 13 can restrict the movement trajectory of the screw 5, so that the screw 5 will not shift left or right during installation, thus affecting subsequent use.

[0033] In this embodiment, the upper electrode housing 1 is also provided with an insulating rubber ring 6 located below the strong magnet 4. The spring 3 pushes the strong magnet 4 to abut against the insulating rubber ring 6, and the insulating rubber ring 6 abuts against the inner wall plane of the through hole 12.

[0034] The insulating rubber ring 6 can prevent the strong magnet 4 from directly contacting the inner wall of the upper electrode housing 1, thus avoiding wear and affecting the service life of the strong magnet 4.

[0035] In summary, during use, the insulating rubber ring 6, the strong magnet 4, and the spring 3 are placed sequentially inside the upper electrode housing 1. Then, the polyurethane insert 2 is embedded into the upper surface of the upper electrode housing 1. The polyurethane insert 2 compresses the spring 3, and the spring 3 pushes the strong magnet 4 to abut against the insulating rubber ring 6. The insulating rubber ring 6 abuts against the inner wall plane of the through hole 12. Then, the shank of the screw 5 is inserted from the lower surface of the upper electrode housing 1. The strong magnet 4 can generate an upward attraction force on the screw 5 until the head of the screw 5 abuts against the end face of the upper electrode housing 1. The two form a clamping force, which can fix the screw 5 inside the upper electrode housing 1.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
