Description

Technical Field

[0001] This utility model relates to the field of applied technology in the machinery industry, specifically to a jig for disassembling aluminum rivets. Background Technology

[0002] If defects occur after riveting electronic products or components, the rivets need to be removed for repair. The traditional method is to use a hammer and screwdriver to pry up the riveted boss and then knock the rivet out. When prying up the riveted boss with a hammer and screwdriver, the screwdriver is prone to slipping, damaging the product surface and rendering it unusable. Furthermore, manually hammering is time-consuming and labor-intensive, requiring 6 minutes to remove each rivet, resulting in high labor intensity. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model solves the problem of screwdriver slippage during rivet removal, which damages the product and renders it unusable. It provides a fast and safe rivet removal clamp. To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a disassembly fixture for aluminum rivets, including an operating platform, a fixing structure for holding and disassembling products on the operating platform, and a rivet disassembly mechanism on the side of the platform. The rivet disassembly mechanism includes three guide columns perpendicular to the operating platform and triangularly positioned, a guide plate parallel to the operating platform, a spring supporting the guide plate, a pressing cam that pushes the guide plate up and down along the guide columns, and a rivet disassembly pin that aligns with the product to disassemble the rivet. The guide plate is movably connected to the guide columns, the spring is sleeved on the guide columns and is set at the lower end of the guide plate, the side of the pressing cam rolls in contact with the upper surface of the guide plate, the pressing cam is provided with a force-applying crossbar, the two ends of the crossbar are fixed on two symmetrical guide columns, and the rivet disassembly pin is set on the lower end surface of the guide plate.

[0004] The guide plate is movably connected to the guide post, and a spring is sleeved on the guide post and located at the lower end of the guide plate. The side of the pressing cam rolls in contact with the upper surface of the guide plate, and the rivet removal pin is located on the lower surface of the guide plate. When the side of the pressing cam rolls, it pushes the guide plate to move downward along the guide post, and the guide plate drives the rivet removal pin to align with the product and perform a rivet removal action.

[0005] Further: In the aforementioned aluminum rivet disassembly fixture, the guide plate is T-shaped, with its two lateral ends fixed to two symmetrical guide posts. The guide plate has a rolling groove on its vertical side to facilitate the downward rolling of the pressing cam. A rivet removal pin base post is located on the lower end face of the guide plate, directly opposite the front end of the rolling groove, and the rivet removal pin is fixedly mounted on the rivet removal pin base post. The pressing cam has a handle for easy operation. The upper end of the spring also has a long cylindrical bearing for fixing the upper end face of the spring; the long cylindrical bearing is located on the lower end face of the guide plate and is sleeved on the guide post.

[0006] Alternatively: The upper end of the spring is also provided with a long cylindrical bearing for fixing the upper end face of the spring, the long cylindrical bearing passing through the guide plate, and the guide plate being fixedly sleeved on the long cylindrical bearing.

[0007] Furthermore, in the aforementioned aluminum rivet disassembly fixture, a triangular fixing plate is provided on the top surface of the guide post. The upper surface of the fixing structure is provided with clips and stops for securing the product.

[0008] Compared with existing technologies, the above-mentioned aluminum rivet disassembly fixture includes an operating platform with a fixing structure for holding and disassembling the product. A rivet disassembly mechanism is located on the side of the platform. This mechanism includes three guide pillars perpendicular to the operating platform and triangularly positioned, a guide plate parallel to the operating platform, a spring supporting the guide plate, a pressing cam that pushes the guide plate up and down along the guide pillars, and a rivet disassembly pin that aligns with the product to disassemble it. The guide plate is movably connected to the guide pillars, the spring is sleeved on the guide pillars and located at the lower end of the guide plate, the pressing cam rolls against the upper surface of the guide plate, and a force-applying crossbar is provided on the pressing cam. The two ends of the crossbar are fixed to two symmetrical guide pillars, and the rivet disassembly pin is located on the lower surface of the guide plate. This invention uses three guide pillars and a cam handle mechanism to replace manual hammering, and develops a suitable rivet disassembly pin to eliminate the action of disassembling the boss. Combined with the product fixing mechanism, it achieves fast, labor-saving, and product-indestructible disassembly. Attached Figure Description

[0010] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0011] Implementation method one: such as Figure 1A fixture for dismantling aluminum rivets includes an operating platform 1, a fixing structure 2 for holding and dismantling products on the operating platform, and a rivet dismantling mechanism on the side of the platform. The rivet dismantling mechanism includes three guide posts 3 perpendicular to the operating platform and triangularly positioned, a guide plate 4 parallel to the operating platform, a spring 5 supporting the guide plate, a pressing cam 6 that pushes the guide plate up and down along the guide posts, and a rivet dismantling pin 7 that aligns with the product to dismantle the rivet. The guide plate 4 is movably connected to the guide posts 3, the spring 5 is sleeved on the guide posts and located at the lower end of the guide plate, the pressing cam 6 rolls against the upper surface of the guide plate, and the pressing cam 6 has a force-applying crossbar 8, the two ends of which are fixed to two symmetrical guide posts 3. The rivet dismantling pin 7 is located on the lower surface of the guide plate. The guide plate 4 is T-shaped, with its horizontal ends fixed to two symmetrical guide posts, and its vertical direction has a rolling groove 9 to facilitate the rolling downward pressure of the pressing cam. The lower end face of the guide plate is positioned opposite the front end of the rolling groove 9 and is provided with a rivet pin base post 10. The rivet pin 8 is fixedly mounted on the rivet pin base post 10. The pressing cam 6 is provided with a handle 11 for easy operation. The upper end of the spring is also provided with a long cylindrical bearing 12 for fixing the upper end face of the spring. The long cylindrical bearing 12 is located on the lower end face of the guide plate and is sleeved on the guide post. A triangular fixing plate 13 is provided on the top surface of the guide post. The upper end face of the fixing structure 2 is provided with a product fixing clip 14 and a stop block 15.

[0012] Implementation Method Two: (e.g.) Figure 2 Unlike the first embodiment, the upper end of the spring is also provided with a long cylindrical bearing 12 for fixing the upper end face of the spring. The long cylindrical bearing 12 passes through the guide plate 4, and the guide plate is fixedly sleeved on the long cylindrical bearing 12.

[0013] When the aluminum rivet disassembly fixtures of the two embodiments described above are in operation, the product with the aluminum rivet to be disassembled is placed on the fixing mechanism 2. By manually pressing down the handle 11, the pressing cam 6 is driven to rotate. The rotating pressing cam 6 presses down the guide plate 4. The guide plate 4 drives the rivet disassembly pin 7 to align with the aluminum rivet and perform the disassembly action. When the rivet disassembly pin 7 acts on the aluminum rivet, under continuous pressure, the rivet pin is pressed out of the product. When the hand is released, the spring 5 is released, and the spring force pushes the guide plate 4 to move upward, and the entire fixture is reset, completing the disassembly action.
