Description

Technical Field

[0001] This utility model relates to the field of welding technology and is a grounding clamp for anti-sparking of electric welding machines. Background Technology

[0002] As a crucial accessory for welding machines, the performance of the grounding clamp directly impacts welding quality and operational safety. During welding, the grounding clamp must withstand prolonged, high-power, and high-current operation, placing high demands on its materials, structure, and design. Prolonged, high-power, and high-current welding operations can easily lead to overheating of the grounding clamp, causing problems such as softening of the springs and reduced clamping force. Under high temperatures, the springs of the grounding clamp can easily lose elasticity, resulting in insufficient clamping force and inability to effectively secure the weldment, leading to arcing. This not only affects welding quality but may also cause fires or electric shocks.

[0003] Furthermore, existing grounding clamps are mostly thin-plate structures, resulting in poor durability and short service life. Thin-plate grounding clamps are prone to deformation and damage, requiring frequent replacement and increasing operating costs. Simultaneously, many grounding clamps lack versatility, making them difficult to adapt to weldments of different thicknesses, shapes, and materials, thus limiting their application range. For example, some grounding clamps are only suitable for plates of specific thicknesses, failing to meet the welding requirements of different specifications of weldments. The conductivity of some grounding clamps is also unsatisfactory, affecting welding efficiency and quality. Grounding clamps with poor conductivity increase resistance, leading to energy loss, reduced welding efficiency, and potential welding defects. Moreover, some grounding clamps are not convenient to operate, with cumbersome installation and disassembly processes, reducing work efficiency. For example, some grounding clamps require tools for installation and disassembly, increasing operational difficulty and time. Therefore, developing a multifunctional grounding clamp device with a reasonable structural design, excellent performance, safety and reliability, convenient operation, and adaptability to various welding needs is of significant practical importance. Summary of the Invention

[0004] This utility model provides a grounding clamp for anti-sparking welding machines, which overcomes the shortcomings of the prior art. It can effectively solve the problem that existing grounding clamps cannot adapt to welding parts of different thicknesses, shapes and materials, and can further solve the problem of cumbersome installation and disassembly process of existing grounding clamps.

[0005] The technical solution of this utility model is achieved through the following measures: A welding machine anti-sparking grounding clamp includes an upper clamping plate, a lower clamping plate, an adjusting bolt, a fixing rod, a rotating handle, and a clamping assembly. The upper clamping plate has an adjusting screw hole that runs vertically through the middle. A fixing rod is fixedly installed on the lower right side of the upper clamping plate. A lower clamping plate is provided below the upper clamping plate. An adjusting hole and an installation hole are respectively provided on the lower clamping plate corresponding to the positions of the adjusting screw hole and the fixing rod. An adjusting bolt is fixedly installed in the adjusting screw hole by a threaded connection at the upper part of the adjusting hole. A rotating handle is fixedly installed at the upper end of the adjusting bolt. The lower part of the fixing rod is located in the installation hole. A clamping area that can clamp the workpiece to be welded is formed between the lower left side of the upper clamping plate and the upper left side of the lower clamping plate.

[0009] Anti-slip teeth can be provided on the lower left side of the upper clamping plate and the upper left side of the lower clamping plate.

[0010] The above may also include insulating protective sleeves, with insulating protective sleeves provided on the outer sides of both the left and right ends of the rotating handle.

[0011] The above may also include storage hooks, which include a connecting plate, a left hook and a right hook. The left hook and the right hook are symmetrically provided on the outside of the rotating handle.

Detailed Implementation

[0016] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0017] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a central A-axis method, and the positional relationships such as front, back, top, bottom, left, and right are determined based on the layout direction of the attached diagram in the instruction manual.

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0019] Example 1: As shown in the attached document Figure 1 As shown, the anti-sparking grounding clamp for the welding machine includes an upper clamping plate 1, a lower clamping plate 2, an adjusting bolt 3, a fixing rod 4, a rotating handle 5, and a clamping assembly. The upper clamping plate 1 has an adjusting screw hole that runs vertically through the middle. A fixing rod 4 is fixedly installed on the lower right side of the upper clamping plate 1. The lower clamping plate 2 is located below the upper clamping plate 1. The lower clamping plate 2 has an adjusting hole and an installation hole respectively, corresponding to the positions of the adjusting screw hole and the fixing rod 4. An adjusting bolt 3 is fixedly installed in the adjusting screw hole by a threaded connection at the top of the adjusting hole. A rotating handle 5 is fixedly installed at the upper end of the adjusting bolt 3. The lower part of the fixing rod 4 is located in the installation hole. A clamping area that can clamp the workpiece to be welded is formed between the lower left side of the upper clamping plate 1 and the upper left side of the lower clamping plate 2. A clamping assembly that can be connected to the grounding wire 15 is provided at the right end of the upper clamping plate 1. During use, by rotating the handle 5, the distance between the upper clamp 1 and the lower clamp 2 is adjusted by adjusting the bolt 3, thereby clamping the upper clamp 1 and the lower clamp 2 onto the workpiece to be welded; by setting the clamping assembly, the lug of the grounding wire 15 is fixed to it, thus this embodiment can effectively solve the problem that the existing grounding clamp cannot adapt to workpieces of different thicknesses, shapes and materials, and can further solve the problem of the cumbersome installation and disassembly process of the existing grounding clamp.

[0020] The above-mentioned anti-sparking grounding clamp for welding machines can be further optimized and / or improved according to actual needs:

[0021] Example 2: As shown in the attached document Figure 1As shown, the wire clamping assembly includes an extension part 6, a fixing bolt 7, a fixing nut 8, and a washer 9. The extension part 6 is fixedly installed on the upper right end of the upper clamping plate 1. The extension part 6 has a through-hole for clamping wires, and the fixing bolt 7 is installed inside the clamping hole. The washer 9 is installed on the outer side of the lower part of the fixing bolt 7. The fixing nut 8 is fixedly installed on the outer side of the lower end of the fixing bolt 7 through a threaded connection. During use, the grounding wire lug is fixed by the fixing bolt 7, the fixing nut 8, and the washer 9. Its function is to provide a reliable, convenient, and reusable connection method. The tightening force of the fixing bolt 7 can ensure that a good electrical contact is formed between the lug and the grounding wire 15 clamp, effectively reducing the contact resistance, thereby ensuring the unobstructed flow of the grounding wire 15 and ensuring that the current generated during the welding process can be safely and quickly conducted to the ground, avoiding electrical safety hazards caused by poor grounding. In addition, the bolt fixing method makes the installation and replacement of the grounding wire 15 simple and quick, without the need for special tools or complicated operations, greatly improving work efficiency. In addition, this connection method is highly adaptable and can be compatible with grounding wires of different specifications 15, meeting the needs of various welding application scenarios.

[0022] Example 3: As shown in the attached document Figure 1 As shown, the upper clamping plate 1 and the extension 6 are integrally formed. A fixing rod 4 is fixedly installed on the lower right side of the upper clamping plate 1 by welding, and a rotating handle 5 is fixedly installed on the upper end of the adjusting bolt 3 by welding. During use, the overall structural strength and durability are enhanced by welding or integral fixing, ensuring stable performance during long-term use, reducing maintenance frequency, and improving work efficiency.

[0023] Example 4: As shown in the appendix Figure 1 As shown, anti-slip teeth 10 are provided on the lower left side of the upper clamping plate 1 and the upper left side of the lower clamping plate 2. During use, the anti-slip teeth 10 primarily enhance the overall clamping force of the tool, ensuring a firm grip on the workpiece during welding and preventing sparking or loosening. Additionally, the anti-slip teeth 10 increase friction with the workpiece, maintaining a stable clamping effect even in high-temperature or oily environments. Furthermore, the anti-slip teeth 10 prevent the grounding clamp from sliding or damaging the surface of the workpiece during clamping, thereby improving welding quality and efficiency.

[0024] Example 5: As shown in the attached document Figure 1As shown, it also includes an insulating protective sleeve 11, which is provided on the outer left and outer right ends of the rotating handle 5. During use, the insulating protective sleeve 11 on the operating handle of the grounding wire 15 clamp is primarily for improving safety and preventing operators from accidentally touching live parts and getting electric shocks during welding. The insulating protective sleeve 11 can isolate the current, providing an extra layer of safety for the operator and reducing the risk of electric shock. Furthermore, the insulating protective sleeve 11 also serves to prevent slipping and absorb shock, improving operating comfort and safety.

[0025] Example 6: As attached Figure 1 As shown, it also includes storage hooks, which include a connecting plate 12, a left hook 13, and a right hook 14. The left hook 13 and right hook 14 are symmetrically arranged on the outer side of the rotating handle 5. A connecting plate 12, which can be fixed to the wall, is fixed between the upper ends of the left hook 13 and the right hook 14. During use, by setting the storage hooks and fixing the connecting plate 12 to the wall, the grounding wire 15 clip can be safely suspended, avoiding damage or safety hazards caused by random placement, and separating it from other tools. Hanging storage helps maintain a clean and orderly workplace, facilitates worker access and identification, and avoids misuse of other tools. At the same time, hanging storage also prevents the grounding wire 15 clip from contacting the ground or other objects, reducing wear and contamination and extending its service life.

[0026] Example 7: As attached Figure 1 As shown, the upper clamping plate 1, lower clamping plate 2, adjusting bolt 3, fixing rod 4, rotating handle 5, and the outer side of the wire clamping assembly are all coated with a bright paint layer. During use, spraying conspicuous paint, such as yellow, orange, or red, primarily aims to improve safety, prevent misuse, extend service life, and facilitate management and use. The bright colors clearly identify the grounding clamp, making it easily identifiable on the construction site and alerting people to its presence, thus preventing accidental contact and improving safety, and preventing electric shock accidents. Simultaneously, color differentiation distinguishes the grounding clamp from other tools or equipment, preventing workers from misusing it and causing accidents or equipment damage. Furthermore, the paint can isolate the grounding clamp material from direct contact with the external environment, providing some corrosion protection and extending its service life, especially in highly corrosive environments. In low-light conditions, the bright colors also increase the visibility of the grounding clamp, making it easier for workers to quickly locate and use it correctly. Finally, uniform, conspicuous color spraying also aids in tool management and proper storage, allowing workers to return the clamp to its designated storage area after use.

[0027] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and the best implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
