Description

Technical Field

[0001] This utility model belongs to the technical field of mold riveting, specifically relating to a self-riveting tool. Background Technology

[0002] In the sheet metal fabrication field, self-riveting structures have become a widely used connection structure due to their advantages such as requiring no additional connectors, high assembly efficiency, and stable connection strength. Among them, the flanging self-riveting process, as an important implementation method of self-riveting structures, involves first drilling holes in the sheet metal, then flanging the edges of the holes, and finally riveting the processed sheet metal to another sheet metal to be connected. This plays a crucial role in the assembly of various sheet metal components. Currently, the conventional application of self-riveting structures in the industry mainly relies on two methods: pneumatic riveting or die-press riveting. These two methods can well meet production needs in standardized, high-volume sheet metal fabrication scenarios where component positions are conventional. However, when processing self-riveting structures in specific locations on large sheet metal products such as large chassis, the limitations of existing conventional riveting methods become increasingly apparent. Because large chassis products require multi-directional adjustments during processing according to different procedures and structural requirements, stable fixing is difficult to achieve, and wobbling is highly likely. This necessitates the use of specific tooling to clamp and fix the product when using die-press riveting to achieve the desired result. Therefore, die riveting has inherent limitations.

[0003] In summary, in order to overcome the shortcomings of existing technologies in specific scenarios and improve the efficiency and flexibility of self-riveting in special locations of large products in the sheet metal industry, it is of great significance to provide a new self-riveting rod structure. Summary of the Invention

[0004] To address the shortcomings of the prior art, this utility model provides a self-riveting tool. This self-riveting tool is flexible, can be operated by hand, and is suitable for a wider range of products to be processed, thanks to its bent transition handle and the rivet head provided in the working part. It is versatile.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a self-riveting tool, which is provided with a main handle, a transition handle and a working part in sequence; The main grip section has a linear structure; The transition handle connects the main handle and the working part. The transition handle includes at least two connected curved arm sections. The main handle and the adjacent curved arm sections, as well as the adjacent curved arm sections, are all bent relative to each other. Along the direction from the main handle to the working part, the bending directions of each bend are staggered in opposite directions. The working part has a protruding rivet joint at its end.

[0006] In some implementations, the rivet joint is a spherical structure.

[0007] In some implementations, the working part includes a riveting body connecting the transition shank and the riveting head, the riveting body being a tapered structure with a diameter that gradually decreases along the extension direction of the self-riveting tool.

[0008] In some implementations, the diameter of the rivet joint is larger than the diameter of the end of the rivet body.

[0009] In some implementations, the bending angle α formed between the main grip portion and the adjacent curved arm segment is 90°-120°.

[0010] In some implementations, the end of the main grip portion away from the transition grip portion is provided with a clamping portion for connecting to equipment such as an electric drill.

[0011] In some implementations, the outer surface of the clamping part is provided with a threaded structure for locking, or the clamping part is a hexagonal chuck structure.

[0012] In some implementations, the clamping part is further provided with a magnetic element to attract the [the object]. In some implementations, the main grip portion includes a main grip outer tube and a main grip inner tube, the main grip inner tube being connected to the transition handle portion, and the main grip inner tube being telescopically connected inside the main grip outer tube.

[0013] In some implementations, the main grip portion is provided with at least one through hole, and a locking member is connected in the through hole. One end of the locking member abuts against the inner tube of the main grip to fix the inner tube of the main grip relative to the outer tube of the main grip.

[0014] In summary, this utility model has at least the following advantages: 1. This utility model provides a self-riveting tool. This tool, through its bent transition shank and a rivet head on the working part, offers flexibility, is suitable for handheld operation, and is applicable to a wider range of product types, thus possessing versatility. Specifically, the transition shank connects the main handle and the working part. The transition shank includes at least two connected bent arm segments. The main handle and adjacent bent arm segments, as well as the adjacent bent arm segments themselves, are all bent relative to each other. Furthermore, along the extension from the main handle to the working part, the bending directions at each bend are sequentially reversed and staggered. Compared to traditional linear self-riveting tools, this utility model allows for a wider rotation angle range of the working part during rotation, enabling better contact with the countersunk hole flange of the product being processed, thus offering greater flexibility. Simultaneously, a rivet head for pressing the flange is provided at the end of the working part away from the transition shank. The design of the riveting joint allows the self-riveting tool to be adapted to the countersunk hole of the processed product, ensuring a stable connection between the tool and the product and preventing the tool from easily detaching. Furthermore, the countersunk hole in the product guides the riveting joint, facilitating the successful flanging and riveting process. Therefore, this self-riveting tool supports manual riveting operations. When handling special structural riveting needs that traditional equipment struggles to cover, such as riveting blind spots and complex workstations, it overcomes the limitations of traditional riveting structures that rely on pneumatic equipment, presses, and specialized molds. This self-riveting tool requires no auxiliary equipment or molds, demonstrating significant advantages in versatility, ease of use, and simple operation. Attached Figure Description

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] For ease of understanding, it should be noted that the X-axis in the graph represents the horizontal direction, the Y-axis represents the vertical direction, and the Z-axis represents the vertical direction.

[0021] Example 1: This embodiment provides a self-riveting tool that can complete riveting manually without the need for equipment or molds. It is also not limited by the structure of the product being processed and can be used to process in special locations. It is versatile, easy to use, and simple to operate.

[0022] For details, please refer to the reference. Figures 1 to 4The self-riveting tool extends linearly and is provided with a main handle 100, a transition handle 200, and a working part 300 in sequence. The main handle 100 has a linear structure and serves as the handhold for manual use or as a part for connecting to power-driven devices such as electric drills, pneumatic screwdrivers, and electric screwdrivers.

[0023] The transition handle portion 200 connects the main handle portion 100 and the working portion 300. Specifically, the transition handle portion 200 includes at least two connected curved arm segments 210. The main handle portion 100 is bent relative to adjacent curved arm segments 210, and adjacent curved arm segments 210 are also bent relative to each other. Along the extension from the main handle portion 100 to the working portion 300, the bending directions of each segment are sequentially reversed and staggered. In this embodiment, the transition handle portion 200 includes two curved arm segments 210, namely a first curved arm segment 211 and a second curved arm segment 212. Figure 1 As shown, the first curved arm section 211 bends in a first direction relative to the transition handle 200, and the second curved arm section 212 bends in a second direction relative to the first curved arm section 211, with the positions of the first and second directions being opposite, so that the self-riveting tool forms an integral "Z"-shaped corner.

[0024] In addition, the working part 300 is used to press the flange 440, and the end of the working part 300 is provided with a protruding riveting head 310. The products to be processed include a first part 410 and a second part 420. Both the first part 410 and the second part 420 are provided with corresponding countersunk holes 430, wherein the countersunk hole 430 of the first part 410 is also surrounded by a flange 440. In use, the countersunk holes 430 of the first part 410 and the second part 420 are aligned, and the riveting head 310 of the self-riveting tool is passed through the countersunk holes 430 of the first part 410 and the second part 420. Then, the self-riveting tool is rotated and tilted, and the working part 300 rotates one revolution along the angle of the countersunk hole 430 of the second part 420 and acts on the flange 440, so that the flange 440 on the first part 410 and the countersunk hole 430 of the second part 420 are engaged to open the flange 440, thereby completing the riveting.

[0025] During this process, as the self-riveting tool tilts and rotates, the rivet head 310 rotates under the guidance of the countersunk hole 430, fully realizing the riveting. Simultaneously, because the rivet head 310 extends into the countersunk hole 430, its rotation is restricted by the structure surrounding the countersunk hole 430, preventing it from easily detaching. Furthermore, because the transition shank 200 is corner-shaped, its structure expands the rotation range and depth of the rivet head 310 when the self-riveting tool rotates, achieving the riveting effect of the flange 440, thus making it suitable for riveting in some special locations.

[0026] Example 2: This embodiment further optimizes the structure of the self-riveting tool based on Embodiment 1. The following references further illustrate this optimization. Figure 5 To provide further explanation.

[0027] The self-riveting tool is provided with a main handle 100, a transition handle 200, and a working part 300. The main handle 100 has a straight structure, and the transition handle 200 connects the main handle 100 and the working part 300. Specifically, the transition handle 200 includes at least two connected curved arm sections 210. The main handle 100 is bent relative to adjacent curved arm sections 210, and there are also relative bends between adjacent curved arm sections 210. Along the extension from the main handle 100 to the working part 300, the bending directions at each bend are sequentially opposite and staggered. The working part 300 includes a riveting head 310 located at its end.

[0028] In this embodiment, the rivet joint 310 is preferably a spherical structure. In use, the spherical structure of the rivet joint 310 makes it easier to pass through the countersunk hole 430 and rotate, and the rotation is smooth, allowing for full riveting along the annular pressing edge and increasing the stability of the riveting.

[0029] Furthermore, the working part 300 of the self-riveting tool also includes a riveting body 320 connecting the transition shank 200 and the rivet head 310. The riveting body 320 is a tapered structure with a diameter that gradually decreases along the extension direction of the self-riveting tool, and the rivet head 310 is connected to the end of the riveting body 320. In use, the rivet head 310 passes through the countersunk hole 430, which abuts against the annular side of the riveting body 320. The riveting body 320 with a variable diameter can accommodate countersunk holes 430 or flanges 440 of different sizes, and can also adjust the distance of the self-riveting tool after passing through the countersunk hole 430. It also facilitates full rotation of the rivet head 310 and excellent riveting effect, thereby increasing the versatility of the self-riveting tool.

[0030] It should be noted that in this embodiment, the diameter of the rivet joint 310 is larger than the diameter of the end of the rivet body 320, and the whole is a spherical structure that protrudes relative to the end of the rivet body 320 to achieve excellent self-riveting effect.

[0031] Furthermore, to balance the self-rivet effect and user comfort, this embodiment further optimizes the structure of the transition handle 200 and the main grip 100. Specifically, the bending angle α formed between the main grip 100 and the adjacent first curved arm segment 211 is 90°-120°. Similarly, the angle θ formed between the first curved arm segment 211 and the second curved arm segment 212 is 90°-120°.

[0032] For example, in one example, the included angle α is 100° and the included angle θ is 100°.

[0033] In some embodiments, the main handle 100 can be connected to power equipment such as electric drills, pneumatic screwdrivers, and electric screwdrivers, in addition to being used for hand-held rotation, so that the self-riveting tool can be rotated by the power equipment. Therefore, the end of the main handle 100 away from the transition handle 200 is provided with a clamping part 110 for connecting to these power equipment.

[0034] The clamping part 110 may have a threaded structure on its outer surface for locking, used to securely connect with the power equipment. In some embodiments, the clamping part 110 is a hexagonal chuck structure for connecting with the power equipment. It is understood that this is not a limitation on the structure.

[0035] Furthermore, in order to facilitate the replacement of the self-riveting tool connected to the power equipment, the clamping part 110 of the self-riveting tool is also provided with a magnetic suction component, which is used to achieve quick positioning and adsorption between the self-riveting tool and the power equipment, saving the alignment steps and speeding up the replacement of the self-riveting tool.

[0036] Example 3: This embodiment further optimizes the structure of the self-riveting tool based on Embodiment 2. The following references further illustrate this optimization. Figure 6 To provide further explanation.

[0037] In this embodiment, the self-riveting tool has a telescopic structure, which further enhances the versatility of the self-riveting tool, enabling it to adapt to complex riveting scenarios, including narrow areas and deep cavities. At the same time, it can also improve the flexibility of operation, reduce the difficulty of operation, and has the effect of convenient storage.

[0038] Specifically, the main grip portion 100 includes a main grip outer tube 120 and a main grip inner tube 130. The main grip inner tube 130 is integrally connected to the transition handle portion 200, and the main grip inner tube 130 is telescopically connected inside the main grip outer tube 120. The extension direction of the main grip inner tube 130 is parallel to that of the main grip outer tube 120, and the transition handle portion 200 is bent and connected to the main grip inner tube 130.

[0039] Two through holes 121 are provided on the main grip portion 100. A locking member 122 is connected to the through holes 121. One end of the locking member 122 abuts against the inner tube 130 of the main grip. As the locking member 122 extends into the inner side of the outer tube 120 of the main grip, it applies force to the inner tube 130, confining the inner tube 130 between the locking member 122 and the inner wall of the outer tube 120. The locking member 122 can be a screw or set screw, etc. In use, first loosen the locking member 122, adjust the extension position of the inner tube 130 relative to the outer tube 120, and when the target position is reached, tighten the locking member 122 to fix the inner tube 130 relatively inside the outer tube 120.

[0040] Specifically, to ensure the stability of the main grip inner tube 130 during the use of the self-riveting tool, a stabilizing structure 140 is provided on the inner side of the main grip outer tube 120. In this embodiment, the stabilizing structure 140 is a protruding boss on the inner side of the main grip outer tube 120. The boss surrounds and abuts against the main grip inner tube 130, thereby positioning the circumferential position of the main grip inner tube 130 and preventing shaking.

[0041] In some other embodiments, the stabilizing structure 140 is a silicone pad or rubber pad located between the main grip inner tube 130 and the main grip outer tube 120. The silicone pad or rubber pad tightly wraps around the periphery of the main grip inner tube 130 to prevent the main grip inner tube 130 from easily loosening.

[0042] In some embodiments, the main grip inner tube 130 is generally cylindrical. However, to ensure a tight connection between the main grip inner tube 130 and the locking member 122 and to prevent loosening, the surface of the main grip inner tube 130 is provided with a contact surface for contacting the locking member 122. This contact surface is planar. Compared to a curved contact surface, the structural strength between the planar contact surface and the locking member 122 is enhanced.

[0043] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
