Description

Technical Field

[0001] The utility model relates to the technical field of quick fixture replacement, in particular to a quick replacement structure for a bending fixture of an automobile component. Background Art

[0002] Automotive component bending fixtures are tools specifically designed to bend metal or other material components during the automotive manufacturing process. They are designed to improve production efficiency, ensure bending accuracy, and ensure product quality. These fixtures are widely used in automotive manufacturing, machining, sheet metal processing, and other fields, playing a particularly critical role in the manufacture of automotive bodies, chassis, engines, and other components.

[0003] In the automotive component manufacturing process, a quick-change bending fixture is crucial for improving production efficiency and flexibility. Currently, the process of tightening and removing multiple bolts is tedious and time-consuming, increasing operational complexity and significantly extending fixture change times. In a fast-paced production environment, this time loss can lead to reduced production efficiency.

[0004] Furthermore, the use of multiple bolts also increases maintenance costs. The large number of bolts, susceptible to vibration and impact, leads to frequent loosening and damage. This requires companies to invest more resources in regular inspection, replacement, and maintenance of bolts, driving up production costs.

[0005] Furthermore, the tightening method of multiple bolts can also have a negative impact on the positioning accuracy of the fixture. During the bolt tightening process, inconsistent tightening torque or slight deformation of the bolts can lead to a decrease in the positioning accuracy of the fixture, thereby affecting the processing quality of the product.

[0027] The following is a clear and complete description of the technical solution of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. Example

[0028] See also Figure 1 - Figure 5 As shown, this quick-change structure for automotive bending fixtures cleverly integrates the linkage design of a telescopic device 8 and a fixed fixture 10, enabling rapid adjustment and replacement of the fixture position. Its core lies in a series of precisely constructed components, which, through ingenious mechanical principles, achieve an efficient and stable operating experience.

[0029] The telescopic device 8, which serves as a bridge connecting the fixture 10 to the underlying structure, is designed with flexibility and durability in mind. Through a sophisticated transmission mechanism, it easily and precisely moves the fixture 10 along a pre-set track to accommodate bending requirements for components of varying sizes and shapes. The fixture 10, with its sturdy structure and precise gripping capabilities, ensures the stability and safety of the component during the bending process.

[0030] To ensure a secure connection between the connecting block 7 and the fixed block 6, the designers cleverly incorporated a guide rod mechanism. The first guide hole 12 on the upper end of the connecting block 7 precisely aligns with the second guide hole 13 on the fixed block 6. The guide rod inserted into these holes not only serves as a stop but also ensures a smooth and precise connection. Furthermore, the smooth end of the guide rod effectively reduces friction and improves the overall efficiency of the structure.

[0031] To further enhance the convenience of fixture replacement, this structure utilizes an innovative quick-disassembly system. The semi-circular rod design, consisting of the first and second screws 14, 15, achieves a tight connection between the fixed block 6 and the connecting block 7 through threaded adaptation. The circular tube and hexagonal nut design of the fastening nut 16 further simplify and expedite assembly and disassembly. As the fastening nut 16 rotates, the anti-slip gasket on its end prevents slipping, enabling quick and secure assembly and disassembly of the connecting block 7 and the fixed block 6.

[0032] To meet the needs of various production scenarios, the fixture structure is equipped with a combination of a lifting rod 11 and a rotary slide 3. Driven by a rotary drive 4, the lifting rod 11 can move the fixed fixture 10 and telescopic device 8 up and down to accommodate bending operations at different heights. The rotary slide 3 moves freely along the slide rail 1, further expanding the fixture's operating range. The screw holes on the mounting base 2 ensure the stability and reliability of the entire structure during operation.

[0033] The fixture structure also demonstrates exceptional design in its attention to detail. The anti-slip pad between the fixing block 6 and the connecting block 7 effectively prevents loosening due to vibration or external forces. The threaded connection between the connecting block 7 and the guide rod ensures a secure and precise connection. The smooth end of the guide rod reduces friction and improves the overall efficiency of the structure.

[0034] Since its introduction, this rapid-change mechanism for bending fixtures for automotive parts has garnered widespread attention and acclaim within the automotive manufacturing industry. Its efficient and convenient operation significantly improves production efficiency while also reducing labor intensity and production costs. With the continuous development and advancement of automotive manufacturing technology, this mechanism is expected to be more widely adopted and promoted in the future, contributing further to the intelligent and automated advancement of the automotive manufacturing industry.

[0035] The replacement process is as follows: The operator needs to rotate the fastening nut 16, utilizing its circular tube and hexagonal nut design to loosen the connection between the fixed block 6 and the connecting block 7. The anti-slip washer ensures that the nut does not slip during rotation. After the fastening nut 16 is completely loosened, the connecting block 7 can be easily separated from the fixed block 6. At this point, the guide rod has been withdrawn from the first guide hole 12 and the second guide hole 13, completing the initial separation of the connecting block 7 and the fixed block 6.

[0036] Next, the operator can operate the telescopic device 8, using its precise transmission mechanism to move the fixing fixture 10 along the preset track to a position that is convenient for disassembly. Then, disconnect the fixing fixture 10 from the other components and remove it from the telescopic device 8. Place the new fixing fixture 10 in the appropriate position on the telescopic device 8 and re-establish the connections with the other necessary components. Ensure that the new fixture is securely installed and positioned accurately. Align the connecting block 7 with the fixing block 6, ensuring that the first guide hole 12 and the second guide hole 13 precisely align. Then, reinsert the guide rod into the guide hole to achieve initial positioning.

[0037] Tighten the fastening nut 16 again, and the threaded adapter firmly connects the connecting block 7 to the fixed block 6. The anti-slip washer prevents the nut from slipping during the tightening process, thus achieving a secure connection. Finally, adjust the position of the lifting rod 11 and the rotary slide 3 as needed to accommodate the new bending operation. At the same time, perform the necessary tests to ensure that the new fixture is correctly installed and operating stably. This allows for efficient and convenient replacement of automotive part bending fixtures.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
