Description

Technical Field

[0001] This utility model belongs to the field of riveting technology, specifically relating to a contour template for riveting positioning. Background Technology

[0002] In industrial fields such as aerospace, automobile manufacturing, and rail transportation, the riveting and assembly of thin-walled components such as sheet metal parts and skins is a key process. The quality of riveting largely depends on the accuracy of the rivet hole positions, and the accuracy of marking or drilling positioning is a prerequisite for ensuring the accuracy of the hole positions.

[0003] In riveting processes, especially for riveting tasks involving complex curved surfaces or diverse workpiece structures, accurate positioning is a crucial step in ensuring riveting quality. Traditional riveting positioning often employs dedicated fixed contour templates, which are custom-made positioning molds based on the specific contour shape of the workpiece. While such fixed templates can guarantee positioning accuracy in certain batch production, their applicability is extremely limited. Specifically, every time a different workpiece shape or even a workpiece of the same series with different curvature dimensions is used, a corresponding template must be redesigned and manufactured. This results in high production costs, long production preparation cycles, and template storage and management occupying a significant amount of space, making it difficult to meet the demands of modern flexible manufacturing with diverse product types and small batches.

[0004] To address this, we propose a contour template for riveting positioning. This device can adapt to workpieces of different shapes and curvatures within the same series using a single template, offering strong versatility. Furthermore, the contouring process is rapid, significantly improving production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a contour template for riveting positioning. This device can adapt to workpieces of different shapes and curvatures in the same series with a single template, making it highly versatile. At the same time, the contouring process is fast, which greatly improves production efficiency.

[0006] The specific technical solution adopted by this utility model is as follows: A contour template for riveting positioning includes a hollow substrate with multiple through holes. A movable component is movably disposed inside each through hole. A locking hole is provided on the movable component, and a metal block is hinged to the movable component. A positioning hole is provided on each metal block. Multiple metal blocks form a contour piece. A rotating component is provided on the hollow substrate, and a locking rod matching the locking hole is provided on the rotating component.

[0007] Furthermore, the movable component includes a movable rod disposed inside the through hole, a limiting plate being provided at one end of the movable rod, the metal block being hinged to the other end of the movable rod, a spring being provided on the movable rod, the spring being located between the metal block and the hollow substrate, and a plurality of locking holes being provided on the movable rod.

[0008] Furthermore, the locking lever is L-shaped.

[0009] Furthermore, the rotating assembly includes a threaded rod disposed on the hollow substrate, a threaded sleeve fitted on the threaded rod, and a locking rod disposed on the top of the threaded sleeve.

[0010] Furthermore, a sliding groove is formed on the inner wall of the hollow cavity of the hollow substrate, and a sliding rod connected to the threaded sleeve is provided inside the sliding groove, and the sliding groove and the sliding rod are matched.

[0011] Furthermore, the length of the groove is the same as the moving distance of the locking rod.

[0012] The technical effects achieved by this utility model are as follows: With all moving components unlocked, each component can move freely up and down and oscillate slightly within its through-hole because the locking rod is not inserted into the locking hole. Each metal block can flexibly adjust its angle via hinge points. The workpiece to be shaped is placed on the worktable, and then the hollow substrate is pushed. The metal blocks contact and press against the workpiece, ensuring each block adheres to the workpiece's surface. All metal blocks together form a shape perfectly matching the workpiece's outline. Then, the rotating component is activated, driving the locking rod into the locking hole to lock the moving components. Multiple metal blocks form a stable, rigid, and precisely replicated workpiece shape—the shaped surface. This surface is then placed on the workpiece to be riveted, positioned by marking lines through the positioning holes, and then riveted at the designated locations. This device can adapt to different shapes and curvatures of the same series of workpieces using a single template, offering strong versatility. The rapid shaped-drawing process significantly improves production efficiency. Attached Figure Description

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-4 As shown, a contour template for riveting positioning includes a hollow base plate 1. The hollow base plate 1 has multiple through holes, and a movable component is movably disposed inside each through hole. The movable component has a locking hole 2, and a metal block 3 is hinged to the movable component. The metal block 3 is made of stainless steel or quenched steel. Each metal block 3 has a positioning hole 4. Multiple metal blocks 3 form a contour piece that adapts to different shapes. A rotating component is provided on the hollow base plate 1, and a locking rod 5 that matches the locking hole 2 is provided on the rotating component.

[0017] The movable component includes a movable rod 6 disposed inside the through hole. One end of the movable rod 6 is provided with a limiting plate 7, and the other end of the movable rod 6 is hinged to a metal block 3. A spring 8 is provided on the movable rod 6. The spring 8 is located between the metal block 3 and the hollow substrate 1, and multiple locking holes 2 are provided on the movable rod 6. The spring 8 is a compression spring, and its elastic coefficient is selected according to the weight and contact force of the workpiece to be shaped. Its elastic coefficient can be selected according to the weight of common workpieces to ensure sufficient contact force without making it difficult to press down.

[0018] When the metal block 3 comes into contact with and is pressed against the workpiece, the movable rod 6 moves inside the through hole and compresses the spring 8 to make displacement, forming a stable, rigid, and precisely replicated contour surface that replicates the shape of the workpiece.

[0019] The locking hole 2 is matched with the locking rod 5. This arrangement allows the locking rod 5 to enter the locking hole 2 without jamming or interference.

[0020] The rotating assembly includes a threaded rod 9 disposed on the hollow substrate 1, a threaded sleeve 10 sleeved on the threaded rod 9, and a locking rod 5 disposed on the top of the threaded sleeve 10. By rotating the threaded rod 9, the threaded rod 9 drives the threaded sleeve 10 to move, thereby causing the locking rod 5 to enter the locking hole 2 or the locking rod 5 to be pulled out of the locking hole 2.

[0021] The hollow substrate 1 has a groove 11 on the inner wall of the hollow cavity, and a slide rod 12 connected to the threaded sleeve 10 is provided inside the groove 11. This arrangement allows the threaded sleeve 10 to move horizontally.

[0022] The slide groove 11 is matched with the slide rod 12. This arrangement allows the slide rod 12 to move inside the slide groove 11 without getting stuck.

[0023] The length of the slide 11 is the same as the moving distance of the locking rod 5. This setting can not only limit the sliding rod 12, but also prevent the locking rod 5 from moving too much and causing movement interference.

[0024] The working principle of this invention is as follows: All moving components are in an unlocked state. At this time, since the locking rod 5 is not inserted into the locking hole 2, each moving component can move freely up and down and swing slightly within its through hole. Each metal block 3 can flexibly adjust its angle through the hinge point. The workpiece to be shaped is placed on the worktable, and then the hollow substrate 1 is pushed. The metal blocks 3 contact and press with the workpiece, and each metal block 3 adheres to the surface of the workpiece. All the metal blocks 3 together form a shape that perfectly matches the workpiece's shape. Then, the rotating component is activated, driving the locking rod 5 into the locking hole 2 to lock the moving components. Multiple metal blocks 3 form a stable, rigid, and precisely replicated workpiece shape onto a contoured surface. This contoured surface is then placed on the workpiece to be riveted, and positioning is achieved by drawing lines through the positioning holes 4. Riveting is then performed at the positioned locations. This device can adapt to workpieces of different shapes and curvatures within the same series using a single template, offering strong versatility. Simultaneously, the contouring process is fast, greatly improving production efficiency.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
